Sourdough Starter

And speaking of pandemic baking, I finally did something that I’ve been meaning to do for ages: make a sourdough starter1!

Well, I’m attempting to make a sourdough starter, at least. I won’t know for several days if it worked out or not. I decided to go old school and create it from just flour and water and whatever wild yeast are floating around. It takes a bit longer – and I’m sure has a higher failure rate – than making it from packaged yeast, but I figure I have time to spare, so may as well go for it.

My plan is to make this sourdough starter and maintain it and pass it along to others, so that generations from now people will say “This sourdough starter was created during the great pandemic of 2020!” And maybe people will search on the Wayback Machine and find this blog posting and say “So that’s what my sourdough starter looked like on the day it was born!”


The recipe is literally to just mix together and 4 oz of flour and 4 oz of water and then let it sit on the top of your fridge for a day, and then you feed it over several days and hope the yeast start doing their yeast thing.

Here’s what it looked like when I mixed it together today:

Sourdough Starter - Day 1

The consistency at this stage is thick and sticky:

Sourdough Starter - Day 1

And here it is, sitting on top of my fridge:

Sourdough Starter - Day 1

I’ve set a reminder to feed it after 24 hours have passed. Very excited to see what happens over the next few days!

Also, like a good scientist, I decided to make a lab book to document my process:

Sourdough Starter - Day 1 - Lab Book

My friend Paul informed me that if this batch doesn’t work, I should try using pineapple juice instead of water, as it’s the right pH to favourite the good wild yeast. So I have a plan B if this batch doesn’t work.

I promised my friend Heather that she will be the first recipient of my sourdough starter once it is ready to be shared. Heather is a public health nurse on the front lines of the pandemic – translation: she’s a freaking hero! Thanks for everything you do, Heather! You are a rock star!

  1. Since sourdough starter something I’ve never made before, it counts towards my 2020 goal of making foods that I’ve never made before. And then when I bake my first loaf of sourdough bread, it will be another thing I’ve never made before and will count towards my 2020 goal of baking 20 times. And I also have “bake sourdough bread” on my list of 101 things to do in 1001 days, so really this is like the most efficient goal achieving act I’ve ever done! []

#ExtrovertProblems

Those of you who know me in person are probably painfully aware that I am an extreme extrovert. So self-isolation and social distancing are quite a challenge for a social butterfly such as myself. But since lives are literally on the line, I am taking the advice of experts who say to stay the hell away from everyone.

It’s so weird that the best thing we can do from society is literally nothing. Stay at home. So hard to feel like you are doing something important when you feel like you are doing nothing. And yet here we are!

So many things are weird right now. So many things that would be good to do in normal times are the worst things to do now. Like taking public transit instead of cars. Or helping an elderly person cross a street. Or going to the gym. Or visiting a friend or family member who is in the hospital or a long-term care home. Or giving people hugs! The world is topsy turvy.


I’m extremely fortunate that all of my jobs can be done from home. My entire office was put on work-from-home indefinitely starting last Monday. The one face-to-face course that I am teaching this semester was moved to online this past week as well, and my other course was already an online course. I’m developing two other online courses and all of that work can be done from home, so, like I said, I’m very lucky when it comes to work.

In working from home full time for the last week, I’ve noticed that I really miss the little conversations I got to have with my colleagues. Whether it was coming up with a plan to get our work accomplished, or chatting about how our weekends were, or how our families were doing, or sharing recipes for the baked goods that someone brought in to share1, or talking about upcoming vacation plans2 – I always knew that I loved conversations with my colleagues. But I never realized how much I needed them.


In the interest of socializing, I’m making an effort every day to reach out to one or two people I haven’t talked to in awhile to see how they are doing. While we aren’t able to go out for a coffee or go see a movie or anything like that, phone calls, texts, Twitter conversations, and Google Hangouts/Skype/Zoom/FaceTime video call are my lifeline right now. It’s a silver lining that I’m connecting with people I haven’t connected with in a while3.


I also saw on Twitter that some researchers at UBC are doing research on how people are coping with the COVID-19 outbreak ( https://blogs.ubc.ca/coronavirus/ ). So I took their survey and then I signed up for their other study, in which you fill out a morning and evening survey for a week. I think it will be fascinating to see the results of this study, as this situation really is unprecedented and is putting stress on people in so many different ways: worry for ourselves and our loved ones, worry about jobs and being able to pay bills, worry if our healthcare system will collapse under the avalanche of patients that are coming their way, and just the stress that comes from dealing with so much uncertainty (just to name a few).


As I settle into this new way of life that I suspect will be a few months4, I’m trying to do my best to take care of myself, go one step at a time, and make connections with those I care about.

If anyone is up for a call or video chat, hit me up!

  1. Omg, remember the days when you could share food with each other? []
  2. Omg, remember when you used to be able to travel to places?? []
  3. In addition to being an extrovert, I’m also an optimist! []
  4. Oh please, let it only be a few months! []

Happy 5th Workiversary To Me!

5

There have been a few times in my life when I decided to do something and then, as the thing approached I thought “What have I done? This is too big and too scary and too hard and I’m totally not going to be able to handle this!”. Moving across the country to do a PhD. Play in a hockey game that lasts for 10 days. Do an MBA part-time while still working full-time. Accepting my current job. As it turned out, all of these were things that I could handle and are things of which, as it turns out, I’m extremely proud! It’s almost like being scared that I’ve bitten off more than I can chew is a sign that I’m about to do something awesome.

My job prior to my current job was fun and I learned a lot and I met some great people, some of whom I’m still good friends with (Hi Heather!). But after 5 years in that job, I’d hit a pay ceiling, I’d learned all that I could learn, and so I wasn’t feeling challenged any more. And then a co-worker of mine told me about a job posting she’d seen that she thought I might be interested in. It was a job doing the same type of work (evaluation in healthcare), but taking it to the next level. A leadership position where I’d get to run a team of evaluators to conduct an evaluation of a massive, multi-organization, multi-year project that has the chance to change the face of healthcare in the region. I was excited by the possibilities this job entailed, so I applied and I got the job. And a few days after I handed in my resignation at my old job I thought “Oh my god, what have I done? I know how to do my old job really well. But there’s so much I don’t know about this new job – I have to learn a whole new area of healthcare AND I’ll be the boss of people and that’s a whole new ballgame for me. What if I can’t do it?” What I should have realized then was, just like the PhD, just like the Longest Game, and just like my MBA, that fear was a sign of a great challenge and I’d shown over and over again that I can rise to a challenge.

The last five years have been really interesting. I’ve learned a tonne about health informatics, about applying complexity concepts to the evaluation of an ever changing project, about governance, about managing people, about managing data when you have a large group of people creating and using a huge dataset, and that’s not even getting into what I’ve learned in terms of the findings of the evaluation so far!

I’ve had the opportunity to collect data from 13 healthcare facilities and counting, I’ve built my team up from 2 to 11 evaluators (all of whom are pretty fantastic, I must say), and I’ve presented my work across Canada, as well as in the US and Australia.

And even after five years, I’m not bored. I honestly feel like we are just getting things rolling and we are improving our processes at every step, and I’m learning so much from all the amazing people on my team, and we are producing information that is actually getting used by decision makers. And there’s so much more still to come.

This is not to say that it’s been easy, or that I will be easy going forward. In a recent presentation I gave about the project at the Canadian Evaluation Society conference, I used this image to represent my experience:

I also often reference that MC Escher painting where the stairs are going up but also going down at the same time as representing what it’s like to work on the project I’m working on. (I can’t put the image here on the blog because I don’t have copyright permission, but here’s a link to the Wikipedia page on it where you can see the image)

But honestly, it’s kind of OK with me. The real world is messy and things don’t always work out how you planned them, but you learn a lot by going along for the ride.

This and That

So nearly half the year is gone. WTF? I really feel like it was January about 5 minutes ago and now it’s June! And, as I tend to do when I haven’t blogged in a while, I’m going for a bulleted list!

  • May was cray-cray. In addition to my week in Prince George for work, I was away another week in May – first at the Canadian Evaluation Society conference in Halifax and then I stopped in Ottawa for a few days to visit Sarah and Dave.
  • The highlight of the conference for me was that the team that I coached for the student case competition won! They worked really hard and produced a kick ass evaluation proposal presentation – I was beaming with pride for the whole conference!
  • It’s a funny thing to be a coach of a winning team. They did all the work and I kept getting congratulated! Not only at the conference, but I got congratulated by someone on the plane on my flight from Halifax to Ottawa and again by someone at the baggage carousel in the Ottawa airport.
  • I decided to do a stopover in Ottawa since I was flying all the way across the country, I figured I should make it worth my while. I hadn’t seen Sarah and Dave in eleventy billion years… or possibly two years which is (a) much longer than I usually go without seeing them and (b) far too long. I’m glad I was able to spend a few days just hanging out, catching up, and chilling with them. I may have also gotten them and their kids addicted to Pokemon Go. And they introduced me to Pokemon battles with trading cards (which is so much more challenging than PoGo) and to the TV show, so now I feel much more well versed in Pokemon.
  • Speaking of their kids, omg, their kids are adorable. And sweet. And very funny! Their youngest, Susannah, when asked if she preferred to calling me Aunt Beth or Dr. Snow, said she preferred Aunt Beth because “what is she, a doctor for cold people?” At first we thought she meant a doctor just for people who had a cold… and then we clued in that she was being much more clever!
  • Since I’ve been back, I’ve had a flurry of work to do – it took me a good week to clear through the back log of emails, but I ended Friday by checking off a lot more things from my to do list than I thought I would, so that made me a happy camper.
  • Making me less of a happy camper is that I’m *still* rehabbing my knee. I was expecting it to be a couple of weeks to heal and it’s been nearly two months! I’ve had it worked on by various health care professionals and my trainer at the gym gave me a knee-friendly training program (basically stuff to work on strength and stability in my leg, plus some stuff to make my biceps look awesome. Not that that will help my knee, but it gave me something where I could push myself without risking my knee and who doesn’t want to have awesome biceps, amirite?). The chiro tested my knee out today and I could see that it was actually improved – more stable and also I don’t have discomfort on the part of the MCL below the knee like I used to -only a bit of discomfort on the part of the MCL that is above the knee. So that made me feel better because I was thinking that the healing had plateaued, but now I think it’s just that it’s been getting better so gradually that it’s hard to tell from day-to-day.
  • My knee has been better enough to play hockey, as long as I wear a knee brace. I played two weeks ago (and scored a goal, I might add!), then was away for a week, and then played again this past week. So that makes me happy. And as an added surprise, someone who I played in the Longest Game with just joined my summer team, so that’s fun!

So pretty much catches you up with what’s new with me. And now that I’m back from my various travels, I guess I should figure out what I’m doing with my summer!

A Very Long-Winded Explanation of Why I Haven’t Blogged in Nearly a Month

Hey, remember that time I agreed to teach all of the courses in the universe this semester, in addition to my day job, while saying “this is a terrible idea and I’m going to be so freaking exhausted for the entire four months of this!”? but then also “but they will pay me money and that mortgage doesn’t pay itself!” Well, it turns out that I was right on both of those counts. Since December (when I started working on all of this stuff in earnest), my calendar has been jam packed with course prep, teaching, and marking for three courses:

One course is an online stats course that I’ve been teaching at the Justice Institute since 2011. After having taught it eight times already, I’m pretty happy with the course and only need to make minor tweaks to the course material. The majority of my work for the course is marking assignments – so I put it into my calendar when those are due to make sure that I get through them as quickly as possible.

My second course is also at the Justice Institute – late last year, they asked me if I’d be willing to teach a class on data and research management (using Excel as a tool for managing data and doing some data analysis). This class is on campus – right in my very own town!1 – and it’s a night course – so I actually can teach it despite having a day job. I’m a huge nerd, so this is actually stuff that I really enjoy. Plus, the JI lets sessionals in on the pension plan (which no other school that I teach at does) and I’m down for some extra free money.

And then the opportunity to teach a Program Planning & Evaluation course at UBC over a couple of weekends in March arose. I’ve taught a Program Planning & Evaluation course a few times and while this one I’m teaching in March is shorter (1.5 credits instead of my usual 3 credits) and it’s a different audience (people in leadership roles rather than those earlier in their career), I have all the content I need for the course – I just need to streamline it, create assignments better aligned to the audience and the duration and structure of the course schedule, and devise some learning activities around that content2 – all of which I have underway. The course is at the downtown campus, which is so much more convenient than having to trek out to Point Grey!

Anyhoo, all this to say that this has been me since mid-December and will continue to be me until the about mid-April:

I’m going to also write a quick posting about all the various things that I haven’t posted about in the last month, but I’ll do that as a separate posting because I imagine most people stopped reading this boring posting several paragraphs ago.

  1. So much better than trekking up Burnaby mountain to teach. []
  2. Active learning is always great, but when teaching half and full days as I will be in this course, it’s a necessity – no one wants to hear me lecture for 8 hours! []

Stuff I Learned This Year: Trademark Edition

Another thing I learned this year is how to register a trademark in Canada.

Did you know that for just $2501? All you need to do is to fill in a simple form (with your name and address, what you want to trademark, what goods and/or services will be associated with your trademark and how you intend to use it), send them $250 ,and then wait.

After you file your application, the Canadian Intellectual Property Office (CIPO), will review your application to make sure that what you want to trademark can be registered (e.g., make sure it’s not in conflict with an existing trademark). If your application is approved, it gets published in the “Trade-marks Journal” for two months, during which others can oppose it). If it doesn’t get opposed (or if the opposition isn’t successful), your application will be “allowed”. Then you pay another $200 to register the trademark.

Once registered, you have 3 years to use the trademark – and it’s a case of if you don’t use it, you lose it! After 15 years (and every 15 years thereafter), you have to pay a renewal fee of $3502.

So it’s actually a pretty simple process – assuming that no one opposes your trademark. If they do, you have to provide evidence and written arguments and it could even end up going to court – which I’m sure would end up being pretty costly!)

Anyway, it’s all summarized here on the Government of Canada’s website, if you are interested: http://www.ic.gc.ca/eic/site/cipointernet-internetopic.nsf/eng/wr04355.html?Open&wt_src=cipo-tm-main 

  1. $300 if you want to file on a paper form instead of online – but why would you, really? []
  2. $400 if you file on paper – but again, why would you? []

Stuff I Learned This Year: Mobile Mesh Networks

This is actually something I learned quite some time ago, but never got around to documenting here on ye old blog1

My good friend, and NTBTWK’s Official Statistician & Tattoo Consultant, Dr. Daniel J. Gillis, is doing some really cool work in northern Labrador with Mobile Mesh networks. But what is a Mobile Mesh network, you ask? That’s a good question – and one that I asked the good doctor at some point – I can’t remember exactly when, but I’m pretty sure it was over a pint of beer or a dram of whiskey.

Basically, a mobile mesh network is where you have a bunch of cell phones that are all connected to each other to make up a network and you can use that to send communications throughout the network – even if you don’t have a connection to the Internet (since you are all connected to each other). It’s useful in places that don’t have good Internet connectivity – like the far north for example or other remote communities.

But if you’d like a more sophisticated explanation than my admittedly underwhelming explanation for something that is actually really cool, I know of two places where you can listen to the good doctor talking about this stuff.

  1. Dr. Dan and his friend and colleague, Dr. Jason Ernst, were interviewed about their work on Mobile MeshNetworking.on the BBC World Service!  You can go here to listen to the experts talk.
  2. Dr. Dan was a guest expert on an episode of the podcast “School of Batman”, which you can listen to here (just scroll down to the episode called “The Quakemaster’s Aftermath”)

I’m looking forward to seeing how this technology ends up playing out – and what things emerge from improved connectivity in remote communities!

  1. In fact, WordPress tells me that I started this blog posting on January 23, 2018 and then proceeded to not finish for seven months. Better late than never, I guess? []

Stuff I Learned This Year: Excel Edition

I <3 spreadsheetsI like to think of myself as rather proficient in using Microsoft Excel.1. I use it for everything from keeping simple lists to advanced data analysis. I love pivot tables and conditional formatting and even have a favourite Excel function2 The other day at work I taught a bunch of colleagues, who are all very well versed in the use of Excel3 that you can copy something from one cell down a whole column by double clicking on the bottom right corner of the cell you want to copy. Most of them knew that you can grab that bottom right corner and drag it down as far as you’d like to copy, but they were all suitable stunned with the double clicking trick – which comes in especially handy if you have hundreds or thousands of rows of data – that’s a lot of scrolling if you are using the drag method instead.

Which brings me to the new thing I learned about Excel. It has a limitation that I’ve never run into before, but which is now an issue for me. Specifically, that limit is the number of rows you can have in a single worksheet. That number: 1,048,576 4,5. And I learned this as a particular set of data that I’m working with had more than a million rows of data! Our makeshift solution is to have multiple worksheets in a workbook, though now that we have almost filled our our *second* worksheet, it really slows down the old laptop!

Clearly, the next thing I have on my “things to learn this year” list is database management!

  1. One of the things that I do in the statistics course that I teach over at the Justice League is make sure that everyone who takes my class can use Excel properly – it’s probably one of the most useful thing they use in the course, to be honest []
  2. CONCATENATE. Mostly because the word is awesome. I probably use “Text to columns” more often, but I love to say “concatenate”! []
  3. Including one who I’d say is the best Excel user I know. []

Five More Books Read

I totally thought I posted this several days ago, but when I just logged into my blog to write another blog posting, I first discovered my blog was completely down (thanks, Kalev, for fixing it for me super fast!) and then discovered that I had not, in fact, hit “publish”. So here it is – it’s very, very long and probably no one other than me actually cares about any of this!

And speaking of combining a bunch of stuff that I’d usually write as separate blog postings into one posting, I’ve read a bunch of books for far this year. And by “bunch” I mean seven, two of which I have already blogged about. Here’s my summary of the other five.

Be warned: SPOILERS AHEAD!

Also be warned: this is very long and may be of interest to no one but me (especially my nerdy notes from Brain Rules and my diatribe against The Unincorporated Man).

The Good People by Hannah Kent

I read this book for my book club and I really, really liked it. It’s set in Ireland in the 1820s and is centred on Nora, a woman who is caring for a young grandson (who has severe disabilities) after her daughter died and then right in the start of the book, her husband dies too. She believes that her real grandson has been taking away by fairies (she also believes that fairies were involved in her daughter’s death). So the book follows along as she struggles to deal with all this and I found that I had to get quite far into the book before I could tell if this was meant to be set in the real world (i.e., one in which people had a belief in the existence of fairies) or a world in which fairies actually existed. The characters clearly believed that fairies existed, affecting all sorts of things in their life – like whether the cows gave milk or miscarriages happened or people died or children were afflicted with mental and physical disabilities. It was so believable that I kept thinking – well, this is fiction. Maybe fairies really did steal her grandson! (Spoiler alert: they didn’t). This book was really well written and the story held my attention all the way through. I wasn’t entirely sure how it was going to end up. I’d definitely recommend this book if you are looking for some good fiction.

Brain Rules by John Medina

When I was in Washington last year, one of the keynote speakers at the conference I was at was John Medina. His presentation was captivating and partway through the talk, he explained why. His talk was about how to use what neuroscientists know about the brain to be better teachers – instead of fighting against how the brain works, why not work with it? And he’d been using the techniques that he was talking about to keep our attention and to help us remember the stuff he’d been talking about!

The talk really stuck with me – anyone who had the misfortune of seeing me in the week or so following that event got to hear in great detail all the stuff that I’d learn1. I spoke to the president of the American Evaluation Association (the association whose conference I was at) a bit later in the conference and commented to her on what a fabulous keynote speaker he was and she told me that she’d read John’s book and in addition to getting her to invite him as the keynote, it had made her rewrite all of her lectures for her classes and that I really should read his book. And so I did!

The book is called Brain Rules: 12 Principles for Surviving and Thriving at Work, Home, and School (though I’d say it mostly focuses on the school part of that).2. There were so many fascinating things that I learned from this book – like how memories aren’t really consolidated until about a decade after the event you are remembering, so for 10 years you are just remembering it, and re-remembering it, and remembering the memory of the last time you remembered it – no wonder two people can have different memories of the same event! Another interesting tidbit was that people can pay attention for about 10 minutes at a time before their interest wanes, so as a teacher you need to do something every 10 minutes to catch your students’ attention. Fortunately, he had some tips on ways to catch people’s attention (which I have previously blogged about after I saw his keynote talk in Washington).

I made a bunch of notes about other cool things I learned in this book:

  • Exercise increases blood flow not just to your muscles, but throughout your body – including to your brain. This is one of the reasons that exercise is good for brain function. Another: it also stimulates the production of Brain Derived Neurotrophic Factor 9BDNR), which basically acts like fertilizer for your brain!
  • “Our evolutionary ancestors were used to walking up to 12 miles per day. This means our brains were supported for most of our evolutionary history by Olympic-caliber bodies”. That’s 19 km – or almost a half marathon every day! So sitting for hours on end in a classroom or in a cubicle is definitely not in keeping with what our brains evolved for!
  • Brains of wild animals are 15-30% larger than those of their domestic counterparts (since the wild animals have to constantly be learning, their brains grow and adapt).
  • Brains of violinists are weird – the area of their brains that controls their left hand (which does all the complex movements) are super-sized with lots of complex associations, but the area that controls their right hand (which holds the bow), is tiny and much less complex.
  • Babies are born with about the same number of neuronal connections that adults have, but that number doubles to triples by the time they are 3 years old, and then the brain “prunes” a bunch of those connections so that by the time they are about 8 years old, they are back to the same number of connections as an adult has. And then at puberty the whole thing happens again and then it settles down again as they approach adulthood.
  • “Until five or six years ago3, the prevailing notion was that we were born with all the brain cells we were ever going to get and they steadily eroded in a depressing journey through adulthood to old age. We do lose synaptic connections with age […] but the adult brain also continues creating neurons within the regionally normally involved in learning.”
  • Different regions develop at different rates in different people – so there’s really no point comparing one kid to another to see if they are “ahead” or “behind” – everyone is just different. For example, “about 10 percent of students do not have brains sufficiently wired to read at the age at which we expect them to read.”
  • People perceive meaning before details – so when planning presentations, you have to catch their attention with something meaningful before springing a bunch of facts on them. We just can’t take in the random facts – we need a reason to care about them first.
  • People can’t actually mutlitask: “we are biologically incapable of processing attention-rich inputs simultaneously”. When we think we are multi-tasking, we are really just shifting our attention from one thing to another thing, over and over again.
  • Declarative memory is a memory that you can “declare” like “the sky is blue” and it involves four steps: encoding, storage, retrieval, and forgetting.
  • We forget about 90% of what we learn in a class within 30 days, most of that within the first few HOURS after class.
  • Our ability to recall something is better if we try to recall it under similar conditions to when we learned it (i.e., when we encoded it). For example, deep sea divers who heard 40 random words while floating in the water could remember them better when floating in the water compared to if they tried to remember them on dry land (and vice versa for those who heard the words on dry land). Similarly, if you learn something while high on marijuana or while sad, you’ll remember if better while high or sad, respectively.
  • Memories aren’t stored in a single place in your brain – bits of a given memory are scattered all over the place – and they are “stored in the same places that were initially recruited to perceive the learning event”. And the “more brain structures recruited […] at the moment of learning the easier it is to gain access to the information” later. Having an understanding of “meaning” can help us recruit more regions.
  • “Quality of encoding” = ways that one can later access a memory – and the more you have, the easier it is to access that information later. One of the most important is meaning – if you want to be able to remember something later, you should try to understand what it means (and if you are trying to teach, make sure students understand the meaning of the concept – one great way to do that is to use relevant real-world examples “constantly peppering the main learning points with meaningful experiences”4.)
  • When we remember something, we retrieve it from our long-term memory storage into our working memory and it acts as if it were a new memory and we have to reprocess them – every time we retrieve that memory. This is known as “reconsolidation”. And “present knowledge can bleed into past memories and become intertwined with them as if they were encountered together”. So you can’t really trust your memory to be accurate!
  • One thing that helps improve memory – repetition! In particular, “thinking or talking about an event immediately after it has occurred enhances memory for that event”. And then deliberately re-expose yourself to the information in an elaborate way in fixed, spaced intervals5.
  • There really is a scientific basis to the phenomenon of being an “night owl”:
    • Early chronotypes (or “larks”) are morning people. Most alert around noon, most productive in the few hours before lunch, wake early without an alarm clock, feel ready for bed around 9 pm. About 10% of people.
    • Late chronotypes (or “owls”). Most alert around 6 pm, most productive in the late evening, usually don’t want to go to bed before 3 am. About 20% people. Because of the way society is structured (e.g., 9-5 jobs, schools from 8-3), they accumulate sleep debt throughout their lives
    • Hummingbirds – the other 70% of people. A spectrum, with some being more larkish and others more owlish, and some in between.
    • “Healthy insomnia” = those people who only need 4-5 hours of sleep per day6
  • Our brains naturally want a mid-afternoon nap.
  • Sleep deprivation makes you old, stupid, and fat. More specifically, it:
    • makes you less able to use the food you consume
    • interferes with insulin production and the ability to extract energy from glucose (which the brain needs)

Sex and gender differences in neuroscience and behaviour “has a long and mostly troubled history,” but Medina seems to do a  good job of providing a summary of the area. He talks about how research typically looks at group averages and people often misinterpret the findings to be true of individuals7. And he talks about how seeing differences in group averages often result in people assuming the differences are genetic (nature) as opposed to a result of how society treats people (nurture) – we would actually need to understand the mechanism of something before figuring out nature vs. nurture (or, more likely, to what extend something is nature vs. nurture vs. an interaction of nature & nurture) for a given feature. And since “boys and girls are treated differently socially the moment they are born8, and they are often reared in societies filled with centuries of entrenched prejudice”, it’s very difficult to tease the two apart. Some of the interesting things from this section of the book:

  • Differences in sizes of brain regions and distribution of neurotransmitter distributions have been seen between the sexes, but no one really knows if it means anything substantial functionally.
  • “Mental retardation is more common in males than in females in the general population” – many are caused by mutations in genes on the X chromosome and males only have one copy of the X chromosome, so if they have the mutation, they will express it, whereas females have two X chromosomes, so if a female has the mutation on one X chromosome, but they have the unmutated version on the other X chromosome, they may not see it expressed.
  • Rates of various mental illnesses differ by gender – e.g., males have higher rates of antisocial behaviour and drug and alcohol abuse, whereas females have higher rates of depression, anxiety, and anorexia nervosa.
  • Under acute stress, males tend to fire up the amygdala on the right side of the brain (the one that remembers the gist of things), where females tend to fire up the amygdala on the left side (the one that remembers the details of things)9.
  • Females tend to have better verbal capacity compared to males – with females tending to use both hemispheres of the brain while males tend to use one.

Lecture design:

  • 10 minute segments – each of which covers only one core concept, starting with doing something that catches the audience’s attention, then an explanation of the concept in 1 minute, and then the remainder of the 10 minutes is where you can provide a detailed description.
  • since classes are 50 minutes long, you can cover 5 core concepts
  • start with the lecture plan at the start, and repeat often “where we are” in the lecture plan throughout the lecture (if the audience doesn’t know where a concept fits in with the rest of the presentation, they will have to try to figure it out while trying to listen to you – and we know that people can’t actually multitask!)

5 rules for making a presentation:

  1. use multimedia – people learn better from words + pictures than from words alone
  2. temporal contiguity principle – people learn better when words + pictures are presented simultaneously rather than successively
  3. spatial contiguity principle – people learn better when words + pictures are presented near each other than when they are presented far apart
  4. coherence principle – people learn better when extraneous material is excluded rather than included
  5. modality principle – people learn better from animation + narration than from animation + onscreen text

Astrophysics for People in a Hurry by Neil deGrasse Tyson

I’ve read A Brief History of Time (The Updated & Expanded Tenth Anniversary Edition) by Stephen Hawking several times – I felt like every time I read it, I get a little more out of it10. I felt like Astrophysics for People in A Hurray was a bit of an easier read than a Brief History of Time, and, of course, it is more up-to-date – there’s a lot that’s been learned in astrophysics in the 19 years between the publications of those two books. So I enjoyed Astrophysics and learned some cool things about dark matter and dark energy and the like, though I can’t say I loved it as much as I love A Brief History. I did, however, enjoy this quote, at the start of the book: “The universe is under no obligation to make sense to you” – NDT.

The End of Average: How We Succeed in a World That Values Sameness by Todd Rose

This book was a pretty quick read and I honestly just had to go look at the summary of it to jog my memory on what it was about11! The basic idea of the book is society is built for the “average”, when, in fact, the “average” describes very few (if any) actual people. For example, apparently the US air force measured many aspects of a large number of pilots – arm length, leg length, head size, etc. and built their planes to fit the “average” sized pilot. But then it turned out that there weren’t any pilots who fit that description – a person might have longer legs than average and shorter arms – so then the cockpits they built didn’t’ work for anyone. So then they came up with the idea of making adjustable seats, controls, etc. in cockpits. It’s one of those concepts where you go “yeah, that should be obvious”, but it’s kind of not that obvious, because we do tend to create things for the “average” person, who doesn’t really exist. I remember being at a nutrition conference back in the day where the new “Nutrition Facts” label was being discussed. The Nutrition Facts label tells you how much of various nutrients are in a food and gives you this information as a percentage of the “Daily Value”, where the “Daily Value” is meant to be the amount an “average” person would need of that nutrient (as people of different ages/sizes/sexes need different amounts). It’s meant as a way for the consumer to know if the food contains a little or a lot of a nutrient, but the “Daily Value” ends up being an amount that describes no actual individual. Some other things that I learned in this book:

  • the body mass index (BMI), which is a measure that takes a person’s height & weight and creates a score that is often used to assess if they are overweight, underweight, or the “right” weight (even though it’s not accurate for many people) was originally called the Quetelet Index12.
  • “school bells were introduced into schools to emulate factory bells, in order to mentally prepare children for their future careers”

Anyway, this book had some interesting ideas, but it really should have just been a short essay rather than a full book.

The Unincorporated Man by Dani and Eytan Kollin.

I started this book because I thought the premise sounded interesting. A man who was frozen in our time is woken up 300 years later, where technology has progressed to not only be able to cure him of the cancer that was the reason he had himself frozen, but also so that all diseases can be cured and aging can be reversed and everyone can make themselves to look exactly how they want. The thing with this society though, is that everyone is personally incorporated – when you are born, you are incorporated, with the government getting 5% of your shares, your parents getting 20%, and you get to keep the rest. Until you have to start selling them off to pay for your education or other such stuff. When you lose majority, you lose control of your life – your shareholders get to decide what you do – like they can require you to take a job you don’t want to because you’ll make more money and they want their dividends! Then you spend the rest of your life trying to make majority so you can actually decide what to do with your life. So that was the premise that I thought was kind of interesting and I really only kept reading it because I wanted to see what this world that the authors built was like. But OH MY GOD THE WRITING WAS SO TERRIBLE! For example:

  • there’s an adage in writing referred to as “show, don’t tell” – it means that good writing generally involves revealing the story through action and senses rather than exposition. This book is like 75% exposition – either the narrator goes on for pages telling the reader something, or a character does.
  • the book is written in third person, but the attitude of the narrator seems to shift depending on which of the main characters is featured in a scene. When the protagonist is in the scene, the narrator seems to suggest that personal incorporation is a bad thing (which is, of course, what Justin thinks), but when his nemesis Hektor is being followed, the narrator shifts to suggesting that personal incorporation is what makes society great! For the longest time, I couldn’t tell if the book was meant to be representing this society as a dystopia or a utopia, because the narrator kept changing its views!
  • the authors constantly use obscure words that are really jarring, as they just don’t seem to fit with the flow of the writing. And to make it worse, in several instances they use words incorrectly. I jotted down a few that drove me crazy when I was reading the book:
    • “The justices talked quietly among themselves and seemed to come to a quorum”. What they actually mean is that the justices came to an “agreement” or a “consensus.” “Quorum” means “the number (such as a majority) of officers or members of a body that when duly assembled is legally competent to transact business”13. So if the justices came to a “quorum” if would mean that they had enough justice present to make decisions – not that they’d made a decision (which is what happened in this scene, as they then say “overruled”. If they didn’t already have a quorum, they wouldn’t have even started the trial!).
    • “He turned to see the erstwhile assistant, cup and saucer in hand.” “Erstwhile” means “former, previous”14. This was not a “former” assistant, as he was the same assistant who had just offered him the coffee and had not been fired in the intervening minutes15. – I’m not even sure what the authors were trying to say here, but “erstwhile” is definitely incorrect.
    • The most egregious one, in my opinion, since the whole book is based on this idea of personal incorporation is that they constantly use the phrase “selling short” incorrectly. “Selling short” is when someone essentially thinks that a stock is going to drop in price, so they essentially borrow it from someone who has it today and sell it at today’s (high) price, wait for it to drop, and then buy it back at the new (low) price to give back to the person who they borrowed it from. They pay interest to the person they borrowed it from, but if it works out the way they intended, they make so much money on selling it at the high price so that even after they pay to buy it back at the lower price and pay the interest, there’s enough money left over to make a profit. In this book, however, they constantly say that someone “sold them short” when they mean “you owned stock in me, my stock price dropped, and you sold it!” Which is not only *not* “selling short”, it’s also just a bad idea (buy low, sell high, right?)

And beyond the bad writing, there are so many inconsistencies (big and small), and things that didn’t appear to have any point at all. Some examples:

  • At one point, the narrator says that the Chairman of the big evil corporation became the Chairman at the “tender age of sixty-two”  and that he has been the Chairman for thirty-one years, and then says, “which Justin calculated would make him approximately ninety-three years of age”. So, first of all, 62+31=93 is really not that difficult of a calculation that warrants saying he “calculated” it. Secondly, why “approximately”? If he was 62 years of age 31 years ago, then he is 93 today.
  • In a court scene, Justin’s lawyer says “I think we can all agree that we’re a society that prides itself on the rights of the individual verses the rights of the government or society to force someone into an action contrary to their character or wishes.” But there are many, many instances where people are forced to take jobs that they don’t want to take because they don’t have majority. So how could *anyone*, let alone *everyone* agree to that statement?
  • The “romance” in the book is that Justin falls in love with Neela, his “reanimationist”, which is basically a psychologist who helps people reintegrat into society when they are woken up from being frozen. They make a point early in the book of talking about how this is totally forbidden in this society, explaining that because people are vulnerable when they wake up, it’s viewed as an abuse of power to become involved with them if you are their reamimationist. Society has a such a strong taboo against it, it’s described as being not like just a doctor and patient having a relationship, but like a pedophile molesting a child. And it doesn’t matter how long ago one was their reanimationist, or if they switch to another reanimationist – you can *never* had a relationship with them. So of course they get into a relationship – and for awhile their friends just seem to brush it off (which I can’t imagine someone doing if a pedophile were dating a child!). Then later, out of nowhere, they offhandedly mention that Neela has had her medical license taken away because of their relationship (which seems like it should have been a big deal that it should have been mentioned before!). Then when trying to strike a deal with Justin, Hektor says of the big evil corporation he works for, “we’ll not only put an end to the vicious rumour of your affair, we’ll come right out and support it. Get her reaccredited, even. I already have renowned experts lined up who’d be more than happy to state unequivocally that the client-patient relationship does not count in your circumstance.” First of all, “client-patient relationship” doesn’t make any sense – the “client” and the “patient” are the same person! It’s not like Justin is having a relationship with himself! They actually mean “client-reanimationist” or “patient-reanimationist” relationship (seriously, did this book even *have* an editor?)  Also, how exactly is *supporting* this supposedly verboten relationship going to put an *end* to the rumours – wouldn’t that just be confirming the rumours? And would a company and its experts saying “hey, we support this pedophile-level of perversion and abuse because it doesn’t really count… just ‘cuz we say so” (as she was most definitely the reanimationist who woke  him up) make everyone in society, who supposedly finds it utterly repugnant, just say “OK, it’s fine now. And she can have her medical license back!”

Hektor (the main bad guy), along with many other characters extol the virtues of personal incorporation as making society great, because competition fixes all problems (so things like police and courts and firefighter are all done better now that they are run by corporations) and that people are more free because if they work hard they can get majority. Except that there are many examples of characters who come from rich families who keep majority (presumably because their family just pays for their education) and others who are “penny stocks” that have no hope of ever making enough to buy back their shares. And no one seems to notice this! There’s also a scene where you learn that the digital assistants that everyone has (which are basically like a tablet that everyone carries around and uses to Google things, but has a “personality” that develops the longer you have the device) are actually sentient and then… nothing happens with them. They just have a vote to not interfere with the goings on in the human world because they don’t want humans to find out that they have become sentient. So there was really no point whatsoever of having that in the book16! And then, there was the biggest reveal of all – at the end of the book, we find out the the Chairman of the big evil corporation which has been taking Justin to court to try to force him to incorporate and regularly has people killed to get its way, actually hates incorporation because his mom died while doing a job she didn’t want to do but had to because she didn’t have majority – and he spent his entire life climbing the corporate ladder, getting right to the top, and running the aforementioned evil corporation for ages in the hopes that someday something would happen that would allow him to take down the whole system! Seems pretty far fetched that someone would do all sorts of terrible things, including murder, to support a system that you hate on the off chance that something would happen to allow you to take it all down. I mean, what are the odds that a person who was frozen 300 years ago would not only be discovered, but would also be a super charismatic leader who also refuses to incorporate and would spark a galaxy wide revolution?

Anyway, the TL:DR is terrible writing and lots of stuff that doesn’t make any sense; don’t bother reading.


In conclusion, I’m a bit behind on books for the year – my goal is to read 18 for 2018 and we are already halfway through the year and I’ve only read 44% of my goal. But I’m on holidays right now, so hopefully I can power through a few in the next few weeks.

  1. Including the students in the course that I was teaching at the time, as my very next lecture that I had scheduled for that class was on how to give good presentations! []
  2. He also has a books on Brain Rules for Baby and Brain Rules for Aging Well, though I haven’t read those ones yet. []
  3. This book was published in 2008, so he’s referring to about 2002. I remember learning this in my undergrad in the mid-1990s (though that scientists had discovered that some birds could grow new neurons when they learned new songs, though this was thought of as an anology), so I guess it was well after I finished undergrad that this stuff was discovered. []
  4. I was sooo happy when I read that, as I *love* telling stories to illustrate what I’m teaching. I’ve always felt that it brings the material to life for students – and have be told by several students that they have found this the best part of my classes), so it was super cool to see that this is actually supported by research! []
  5. This is making me think that I should have written up these notes much sooner after I finished reading this book (which was 3 months ago!). I made short annotations in my e-reader as I was reading but had to go back through them all and re-read the sections to make these more coherent notes. Oh well, better late than never! []
  6. I so wish I was one of those people. Think of all the things I could get done! I think I’m a owlish-hummingbird. If I had my druthers, I’d probably get up at 10 am and go to sleep at 1 am. []
  7. Which actually connects with what I was reading about in The End of Average. []
  8. Really, they are treated differently even before they are born – “gender reveal parties” anyone? []
  9. I’m terrible at remembering details of things – and I also think that in many ways I am more male-like than female-like. When I was in my undergraduate, I took first year psychology and we used to be able to get out of doing assignments by participating in psychology studies. One of the studies that I participated in was looking at something to do with males and females (not surprisingly, I can’t remember the details!) but not only testing whatever it was that was usually found to be different between males and females but also whether someone who was male or female identified themselves as behaving male-like or female-like. And if I recall correctly (again, not so good with the details, but remembering the gist of things), I scored more like a male on what they were testing, but I also identified as more male-like in my behaviours. So I guess that fits both with the “group averages aren’t good at describing individuals and that maybe my psychology being more male-like than one would expect of a female (based on said group averages) shows up in this gist-remembering thing… though he did only talk about it being under acute stress and not in general. Anyway, this is getting pretty long for a footnote! []
  10. Come to think of it, I haven’t read it in awhile. I should read it again. []
  11. I also realized that I’d made a few annotations when I read this as an ebook. []
  12. There are a lot of shortcomings of the BMI being used the way it is, which I already knew about. I just didn’t know it was named after this Quetelet guy that is talked about a lot in this book. []
  13. Source: Merriam Webster dictionary []
  14. Source: Merriam Webster dictionary []
  15. In actuality, you find out later in the scene that he is the Chairman in disguise, but that still doesn’t make him a “former” assistant. []
  16. Possibly they are setting up for something in a sequel, but then why not just leave it to the sequel as there is no point whatsoever of having those scenes in this book. As one reviewer on Goodreads wrote,they literally vote to not affect the plot of the book! []

Happy 4th condo-versary to me!

Hey remember that time I bought a condo? Would you believe that was FOUR years ago? Where does the time go?

My mortgage broker sent me an (automated, I’m sure) “happy anniversary of having bought your condo” email, which is what reminded me that tomorrow is 4 years since I took possession of my humble abode. So I looked at my trusty mortgage countdown spreadsheet (because of course I have a spreadsheet) and according to my calculations, I have paid off 53% of my mortgage principal in 4 years. Not too bad, if I do say so myself. Of course, I ridiculously lucked out when I bought this place – the price was very good1, plus I have a few different source of income in addition to my day job, so I have had the luxury of being able to make lump sum payments. Also, I’ve had very little in the way of additional expenses, as my unit has been very well taken care of and the strata does an excellent job of maintaining the building.

Given that the Greater Vancouver real estate market continued to rise at an insane rate since I bought, I’m actually in the position where I own an even bigger proportion of the place than I would otherwise. When I bought the place, I made a 25% downpayment, meaning the bank technically owned 75% of my place. If the price of the place had stayed the same over the past four years, I would now own 65% of my place and the bank would own 35%. But since the value of the place has gone up, I now own 77% of the place if we use the most recent assessed value (which is what the province assessed my place as being worth as of July 1, 2017). If we use the average amount that units in my building that are identical to mine have sold for in the past few months2 (assuming that I could sell my place for that price), I currently own a whopping 82% of my place and the bank owns a mere 18%. It’s a weird situation – I like to remind myself that the “value” of my place is really all just theoretical given that I’m not planning to sell anytime soon. But it does give me the opportunity to do some fun math! #nerdery

Anyway, my next hurdle is that I’ll have to renegotiate my mortgage next year, as my mortgage was a 5 year term. The interest rates are higher now than they were 4 years ago, so I’ll have to pay a higher interest rate. Boo-urns. I guess I have a year to figure out how all that works.

  1. In the context of the time and place in which I bought it. It was an absolutely insane price if you compare it to just about anywhere else in the world. []
  2. Which is almost double what I paid. []
