You may have heard references to Bayes’ Theorem in light of the pandemic and wondered how it is relevant. Well I am here to help. First off, here’s a great guide to Bayes’ Theorem from the website MathIsFun.com. Even if you are math phobic, I think you will be able to read that piece and understand it. Secondly, check out the site Varsity and how it explains how Bayes’ Theorem and COVID-19 testing are related. Both are well worth a read.
Learn Bayes’ Theorem. It’s good to help you understand many things in life, including what is happening during the pandemic.
P.S. This related piece at FT.com explains why you should expect to see vaccinated people in the hospital with covid despite high vaccination rates.
I read many ofpieces on mathematics: here are some pieces I have found worthwhile. Most of them are readable by folks who are not mathematicians.
Here’s a number of good pieces
Finally, This 3 700-Year-Old Tablet is the Oldest Example of Applied Geometry. Cool.

You would think so, if you read this: Sneering at Ontario’s anti-racist math curriculum reveals a straight line to what people value in The Star
What has the columnist angry was the removal of several passages of progressive political text that went with the update to the recent changes of the math curriculum. I can see why that removal would anger some people with progressive political values.
I can also imagine how many conservatives would have been angry if there was text like this removed from a new curriculum: “recognize the ways in which mathematics can be used as a tool to uncover, explore, analyse, and promote actions to address greater productivity and growth within our economy and to lead Canada to a strong future of wealth and opportunity”, or if the government removed anything to do with teachers creating “pro-capitalist and pro-business teaching and learning opportunities.” Any group that tries to explicitly frame a curriculum and then have that framing removed will be upset.
Mathematics itself is not political, but it is always taught within a political and historical context. For example, I have math texts that make it seem that the only worthwhile math came from European men, while I have others that show mathematics has roots all over the world. I have math textbooks that mention 0 women, while other texts show the role women have played in mathematics and delve into why women had a hard time making more of a contribution.
Whatever context you want to frame a curriculum, I think that emphasizing politics and history with regards to teaching mathematics will not achieve some of the goals that progressive thinkers hope it will achieve. I think the new changes in the curriculum with regards to things such as streaming will help achieve those goals, as I wrote here.
Additionally, I think there are other things that can be done outside the curriculum that could help students that are disadvantaged when it comes to education in math. I am thinking of the work done by organizations like BlackGirlsCode. We could use more organizations like that who can provide specialized programs not just to help kids who are struggling with math, but to uplift kids that excel in math. Organizations that can support the next Maryam Mirzakhani, wherever she is. The kids who are struggling with math need more help than what the schools can provide: the same is true for kids that excel in math.

This may be the best book to learn calculus from: Calculus Made Easy.
I like it for two reasons. One, it’s free. Two, it does not take itself seriously nor does it take calculus seriously. To see what I mean, here’s a clip from the beginning of the e-book:
Considering how many fools can calculate, it is surprising that it should be thought either a difficult or a tedious task for any other fool to learn how to master the same tricks. Some calculus-tricks are quite easy. Some are enormously difficult.
The fools who write the textbooks of advanced mathematics—and they are mostly clever fools—seldom take the trouble to show you how easy
the easy calculations are. On the contrary, they seem to desire to impress you with their tremendous cleverness by going about it in the most difficult way.
Being myself a remarkably stupid fellow, I have had to unteach myself the difficulties, and now beg to present to my fellow fools the parts that are not hard. Master these thoroughly, and the rest will follow. What one fool can do, another can.
So if you want to learn calculus but are struggling, give that book a look. Sure it’s an old book, but calculus is an old subject. It may suit you just fine.

I suspect many people will not want to read this article containing great insights on mathematics by Steve Strogatz. That’s a shame, because it is really approachable by anyone of any mathematical ability. It’s especially good for people with limited math skills, because he does a good job of showing the value and benefits to be gained from thinking mathematically. I highly recommend it if you read it.
For example, one thing I found fascinating is his discussion of the Prisoner’s Dilemma by comparing it to religion. You should read it, but in short, it’s been shown that one approach to succeeding in playing several rounds of the Prisoner’s Dilemma is to use a Tit-for-Tat strategy. This is highly effective and is similar to Old Testament Eye-for-an-Eye morality. However that can also go wrong on occasion, leading to long lasting feuds that never get resolved. Then he gets into a discussion of New Testament morality and how that can avoid some of the problems of Old Testament morality. It’s a great discussion, and one of the many great discussions in the article.

Fun! For all you number theory fans out there: 9 Numbers That Are Cooler Than Pi
I still think Pi is pretty cool. But so are these other numbers.
It’s hard to say why this interview with Strogatz is so good, other than to say he covers much ground on a variety of interesting topics and speaks lively on them. (Ok, I find game theory, “elegant” math, math education, etc, interesting, but you likely will too).
If you enjoyed this interview, he has a recent book out, “Joy of X: A Guided Tour of Math, from One to Infinity.” Worth a look.

I knew that Paris had streets named after politicians and historical figures, but I didn’t know how many Paris streets are named after mathmaticians. Apparently quite a few! Amazing. One more reason to love Paris.
Dover publishers have the best books when it comes to math. If you want to see some of their better ones, see this list.

This is a great introduction to the topic of Infinity. I think even people who struggle with math will get this and enjoy it.
Unless you studied mathematics, you likely didn’t know that about infinity. It is fascinating stuff, I find.
