Should I take intro to general relativity, or green's functions and calculus of variations during my last semester of university

I'm in mechanical engineering and I need to take one more 3 credit course to meet full time eligibility, but all the engineering courses either don't fit into my schedule or fucking suck

What's the optimal way to increase my productivity while avoiding burnout?

So far I need scientifically proven tricks like.

Do warm ups before working so the brain enters the right side.

Keep the practice session under 1 hour then meditate using binaural waifu asmr for 30 minutes so your brain rest.

Then switch to a diferent activity.

I have been researching prime numbers for over almost 1 year and a half now (well much less since I was slacking off for some moments).
I had gone deep down to the thicket of ergodic theory, topological algebra and profinite groups in order to understand and share new perspective on primes and their distribution in some irreducible small degree polynomials and yet I feel depressed and bored to the point that I can't finish writing the paper.
How do you force yourself to work after you achieve something and think about how much there is still ahead to complete?

>> No.16179015

It's interesting really, feels like a huge achievement for me and I am eager to share my mental looking math scribbles with the mathematical community but I just can't force myself to complete the work exactly at the moments that I need to wrap it up.
The saddest of all is that this is all well known theory and kinda simple for people who studied the material.

If the universe is infinite, does that mean that we never really die?

Universe is NOT infinite.
It is easy to see that if it were infinite, then energy would not be conserved; an infinite unverse contains an infinite amount of energy and therefore the law of the conservation of energy contradicts an infinite universe hypothesis.
It can at most be a totally bounded space which expands faster than the possible rate of travel.

>>16178649
>Whereas in this finite universe that popped into existence from nothingness, the energy popped into existence as well.
Which means it's still not conserved.
So we've agreed that energy is not actually conserved in either case. Do you have a backup line of reasoning for rejecting the infinite universe?

Expanding space does not imply creation of more energy.
Energy stays the same, the space increases. (This implies that energy density goes to zero with time, but this should be expected).

I attribute the 'curing' or rather symptomatic treatment of my decade long downward spiralling depressive episode to riding the bicycle every day to be honest. But having goals, even if they don't resonate and having people put expectations like showing up on you, even if you don't care about those people helps alot. Just get up, go for a walk now. Go to bed at a reasonable time, set alarm, sleep, wake up and get out with the alarm, get bicycle, go places, be outside, get yourself into obligations. Stick with it. Out of the bed every day, same goes for weekend. Be outside every day. Most importantly start your journey now.

Learn how to write basic proofs. Then pick up

>Model Theory (Chang/Keisler)
>Proof Theory (Gaisi)
>Introductory Set Theory (Levy) or Set Theory (Jech).

All cheap dover books and good. Obviously start with learn propositional logic, first order and then maybe second and higher order. Learn some basic proof, model, and set theory. Maybe learn alternative foundations and perspectivevs like typed/untyped lambda calculus, category theory, general type theory and homotopy type theory. Also helps to learn some programming for computational shenanigans, learn Haskell or Scheme and implement stuff. Learn Coq or Agda, or Lean.

Let's pretend all these things since the '47 are ours, by 'ours' I mean the US government. Thoughts on Quantized Inertia ala' Mach's Principle and magnetic vector potential shielding as a real explanation for these craft. I personally don't believe in anti-gravity, but inertial shielding resulting in a reduction in effective mass... probably. Bonus points if anyone can dig up what the paper citation 38 referring to work by Zel'dovich that isn't listed.
