Some random observations and some links:
i. I’ve written about diabetic hypoglycemia before – I even blogged a book on the topic just a few weeks ago. So I’ll keep this short. Here’s the key observation from the post to which I link: “Hypoglycemia causes functional brain failure that is corrected in the vast majority of instances after the plasma glucose concentration is raised”.
Functional brain failure is pretty much what it sounds like – the brain stops working. The point I want to make here is that hypoglycemia can strike pretty much at any point in time, including when I’m doing stuff like blogging or commenting. I sometimes develop hypoglycemia while deeply engrossed in some intellectual activity, like reading, writing or chess, in part because in those situations I have a tendency to forget to listen to my body’s signals – perhaps I forget to eat because this stuff is really much more interesting than food, perhaps I don’t really care that I should probably take a blood test now because I’d really much rather just finish this book chapter/chess game/blogpost/whatever. That happens. When it happens while I’m blogging, what comes out the other end may look funny. I occasionally write stuff that’s incoherent and stupid. Sometimes the explanation is simple: I’m an idiot. Sometimes other things play a role as well.
This is a variable you cannot observe, but which I have a lot of information about. It’s a variable I’d like readers of this blog to at least be aware of.
ii. Maxwell wrote this post, which you should consider reading. I won’t pretend to have good reasons/justifications for disliking people I conceive of as arrogant, but I do want to note that I do this and always have. Arrogance is a trait I dislike immensely.
iii. Over the last few days I’ve been reading Okasha’s great book Evolution and the Levels of Selection (I’ve almost finished it and I expect to blog it tomorrow) – so of course when Zach Weiner came up with this joke yesterday, I laughed. Loudly:
(Click to view full size. The comic of course has almost nothing to do with the content of the book, but I’ll take any excuse I can get for blogging that comic…)
iv. The Feynman Lectures on Physics. Available to you, online, free of charge. Stuff like this sometimes makes me think we live in a very nice world at this point.
But then I read posts/watch videos like this one and I’m reminded that things are, complicated.
v. A few Khan Academy lectures:
