A little while ago, I wrote about an audiobook called A Short Account of the History of Mathematics. It was recorded to help people sleep and it works.
Lately, my insomnia has been awful. I will sleep for a couple of hours and then I’ll be awake for a couple of hours, wide awake. I have been referring to these nights as history of math nights. After I get fed up with being awake, I’ll turn the audiobook on and I’ll generally be asleep within 15 minutes.
I have to give kudos to whoever thought of recording this. It works wonders when I need it. There’s another one that works for me, too, The Perfect Swing. It just doesn’t have the same ring to it as history of math night.
