And now it’s all this
I just said what I said and it was wrong. Or was taken wrong.

XKCD and Fourier
If you’ve done Fourier series approximations of functions, you had three reactions to today’s XKCD comic :

Squaring the triangle with help
Yesterday, Numberphile released a delightful video with James Grime (redundant, I know) in which he walks us through a geometry problem first posed by Henry Dudeney in 1902. It’s known as the “ Haberdasher’s Puzzle ” and is reproduced in Dudeney’s 1907 book The Canterbury…

HomeView
Given that I typically take a wait-and-see attitude when Apple introduces a new product, I was surprised to find myself ordering a HomeView within a day of its announcement. I was even more surprised when lots of otherwise pro-Apple people— this guy , for example—were skeptical…

TextEdit vs. Pages
A few days ago, Allison Sheridan wrote a very persuasive article about using TextEdit, the “unsung hero of macOS,” as a simple word processor. I’ve been trying it out and… I’m going to stick with Pages. Let me explain why.

Randomizing array indices
I mentioned in my last post that I’m working my way through Practical Deep Learning by Ronald Kneusel. The math so far has been straightforward, and the code is written in Python, which I find easy to follow.

Mean vs mean
I decided to start learning about machine learning a couple of weeks ago. Partly because it sounds interesting, partly because I think I have enough math to handle it, and partly because I felt it was important to have a deeper knowledge if I want to criticize AI.

I’m pissed at the Library of Congress

Making a tall, skinny plot in Mathematica
Yesterday’s post included this plot:

Distorted plots
Rhett Allain, physics professor and blogger, published a nice article today about the Moon’s orbit. It follows largely the same line of reasoning as my post on the same topic (and the various write-ups I linked to in that post) from a few years ago. I nodded my head as I read…

Too dumb for AI
I’ll admit that the first thing I looked into regarding yesterday’s “Super Intelligence” meeting at the White House was whether Tim Cook was there. He wasn’t, which was probably a relief to Tim, even though it’s also an admission that Apple isn’t considered a player in AI. By…

A small probability correction
This short video appeared in my YouTube feed last week. It’s from Hannah Fry , whom you probably know from her appearances on Numberphile and other STEM-oriented stuff. If you’re in the UK, you’ve may have seen her on the BBC, too.

Equinox
The episode of The West Wing that’s always bothered me is “Evidence of Things Not Seen,” which is Episode 20 of Season 4 . It takes place on the day of the equinox (in March, not September, but I remembered it because today is an equinox), and one of the continuing subplots is…
