#142Currently working on textbooks in: Topological Manifolds (Lee: Topological Manifolds) Abstract Algebra (Dummit and Foote) Geometric Algebra (Doran: Geometric Algebra for Physicists) Differential Geometry (Fecko: Differential Geometry and Lie Groups for Physicists) Though I'm less invested in these last two currently, as the diff geo's a prep for the masters I'll be doing and the other is something I'd really like to…

#143I've made a deal with my friend: I'll be teaching him basic Analytic Geometry to support his interest in computer graphics, and he'll be teaching me UI design.

#144- Graphics Design because people really listen when stuff is pretty. - French which has to be done but is quite hard. - Some math because the more I work with computers there more I understand how it would be very useful. - Combat sports because it keeps me fit and its good for your posture if you know how to throw a punch. - Traveling. Never learned it, work too much and would like to see the world before being an o…
I have been "learning" French for 5+ years... what resources are you using that you would recommend?

#145Spanish - more relearning at this point and getting practice. Running - also relearning, which happened quickly this time. I'm already back to running 5ks after just a few weeks (though I also spent 6 months building up my cardio with a rowing machine). How to be offline and focused. Computers (and smartphones) are fantastic tools of distraction. I'm trying to regain my focus overall. Reading physical texts is helpin…
I don't know your background, but be careful ramping up long distance running too soon. Especially if you're running on concrete. It feels good till it doesn't lol
Well, I was only out of it for about 2 years at this point (I ran for 2 months last year, but an unrelated injury pulled me out of it), and before that I ran for about 6 years 2-3 times a week, never less than a 5km (once I got up to doing 5km distances) and did a lot more training during that time too (which often incorporated shorter runs or sprints).
I already took care of the weight I'd gained through improved diet and 6 months of rowing five times a week (got up to 30 minutes of moderate to high intensity). So my cardio condition is great, not where I want it, but great overall. It's really my running form I have to improve, and getting my feet and knees used to the impact again. I'm now back under 180 (versus 210 this time last year) which is a much healthier weight to be running at.
I'm being deliberate about adding distance slowly to minimize the risk of injury (from running). Recovering from an injury at 26 wasn't too bad, at 36 it took a lot longer, and now I'm about to hit 40 so I'm being more deliberate than I would've a decade ago. I'm doing 2x3km runs with a 5-8km run once a week. I plan to add 1-2 total extra kilometers a week and only if the runs have gone decently (don't need to be great, but need to be complete). I have no intention of pushing the short runs past 5km or the long run past 10km. Then I hope to find a soccer league and team I like to get my extra running in on weekends.
When I said I'm running 5ks, it's just the one a week. But I can actually finish it, which was a pleasant surprise (I thought it'd take longer to reach that point).

#146Biology on Khan Academy. We're making plant-based cheese and are experimenting with enzymes to make better and new varieties of cheese. We already have one Ricotta-style cheese (fresh cheeses you often make with acids, so that works well with soy protein, too).
Our hypothesis is that there must be enzymes that works similarly with plant proteins as chymosin (part of rennet used in cheese making) works with casein.
So, I need to catch up on my bio basics to be able to better understand what's going on :-)

Yep, I'm actually in the discord server though I've got it muted because I'm not focused enough on it yet. Hoping to get back into it more deeply next month and be more active. Thanks for the invite!

#149To sleep on my back. Being a life-long side sleeper has caused a lot of shoulder and upper back problems that sometimes make it hard for me to reach out and type. I wish I'd done this ages ago. It's one of the hardest things I've had to learn.
My wife and I have tried this, but it causes each of us to snore intermittently. Did you contend with snoring as you learned to sleep on your back?
This is the main reason I don't sleep on my back, too. Not sure what the solution is if I want to sleep on my back - I'd hate to jump straight to a cpap machine if I don't need to. Maybe those nighttime breathing strips would help?
