- drums - philosophy - higher level math - Nand2Tetris type programming - electrical engineering / robotics - producing/recording music in an ultra cheap home studio type rig (kleinbl00, I seem to remember that you know about how recording music works, or am I wrong about that?) - programming guitar effects (like Pure Data) - practical music theory (for song writing) - physics (particularly quantum physics and string theory) - meditation (hopefully without the bullshit) - cooking - proper exercising (I run and ride my bike occasionally, but that's probably not sufficient to sustainably get in really good shape) Anyone knowing anything about this stuff have some resources they could share?
No Weight Required Full Body Workout, which, apparently, ought to be enought to keep you in shape if done everyday. Haven't tried it yet. There's also 7 Minute Workout, a "scientific" (meaning "scientifically proven") workout designed for the same purpose. Haven't tried that either, probably won't (sounds too good to be true, like that Soilent thing, and too short for any real exercise), but it's worth to share to see if it will work for you.
I've been practicing meditation while doing Taiji Zhan. It's a…different technique. When your legs are on fire, it's easy to think of only one thing. It helps me to think of the willow. The willow does not move on its own. The willow moves only when the wind moves it. I find Taiji in general is good for clearing my mind. No matter how stressful my day, or how anxious I am about things, the forms take all my concentration, and everything else evaporates. Especially in class with others.
If you want to learn and get an intro to quantum physics I would recommend you:How to teach Quantum Physics to your dog by Chad Orzel He even has his blog String theory well there might be better books but I have only read this For higher level math, read this answer on quora: https://www.quora.com/If-you-had-to-teach-yourself-math-from-basic-algebra-to-high-level-mathematics-what-would-be-your-strategy?srid=pbEj&share=1 Learn electric engineering and robotics by doing projects, you can find ALOT of them online. Just start searching and start doing. No better way of learning than doing
Good luck!
