On a completely different topic: After watching my first marriage degenerate and my wife asked me to move out, I was fairly well mystified about what was going on. We'd read lots of books about marriage and communication, planned for it to be tough, intended to see it through... so what happened? "The Seven Principles for Making Marriage Work" by John Gottman was a book that I read after we'd separated that first sta…

I started to read this book but it seems to be full of political bile. How does it compare to Economics in One Lesson?
Can you give an example of "political bile"? Sowell is an incredibly even-keeled writer, and I'm surprised someone would find the book angry (or political, other than believing in traditional economics).

Perhap similarly, on an arduous journey to better my mental health and character I have found much to learn with paradoxical situations arising in zen koans. A good book with plenty of koans was Mumonkan/Gateless gate, in a compilation like this: https://www.goodreads.com/book/show/593516.Two_Zen_Classics They've been helpful as a reinforcement (and contrast) to more logical things, as well as therapies (DBT, CBT).
Thanks for the recommendation. I really want to get into Zen Buddhism (as a form of spirituality that meshes better with my atheism), but after that first chapter the Alan Watts book becomes pretty dense and I need serious time and dedication to unpack its arguments. I probably need something easier to digest.

#324For the uninitiated, wavlet transform is basically Fourier transform on steroids. Not only does it tell you what frequencies are present in a signal, it also tells you when they are present giving you a time vs. frequency plot (similar to short-time Fourier transform). Of course there is a limit to how well you can know both at the same time (just like the Heisenberg uncertainty principle actually!), but it's a very useful tool for studying signals. In my specific case, I was analyzing signals from a pulse oximeter in order to extract the breathing rate from them (https://dl.acm.org/doi/fullHtml/10.1145/3460238.3460254), but it has applications in many other fields such as image processing and compression.

#325How much of a topic clicking is just reading from several different sources, rather than one source being particularly "good"? I often joke with a coworker that we don't fully understand a topic until we have read several textbooks/papers on it. It doesn't really matter how good any one text is. I've always wondered what the mechanism is for this. Is is just a certain amount of exposure to a topic? Or is there truly…
There is a joke in physics that the best textbook on any topic is the third one you read.

#328It’s as if I had seen the world with only 1 dimension instead of 3 for all that time.

#330I'm a software engineer, but these have been instrumental in my success in a way no coding book can compare to(though John Ousterhout's "A Philosophy of Software Design" would have, if it came out earlier in my life). Personal time/task management- The classic, Getting Things Done( https://www.amazon.com/Getting-Things-Done-Stress-Free-Produ... ). The power this has on people cannot be understated. Turns out that mos…
