If homogenous time implies energy, homogenous space inertia, isotropic space angular inertia, then what does isotropic time imply?

The field must've evolved since he wrote the books. What are some areas he doesn't touch upon?

Let's read through Landau!

I don’t know what the format of these threads or the pace of the reading is going to be.
For starters, I will now just try to initiate a conversation by reflecting upon the content I read.

Then I’ll open up the exercises to be done.

>Vol 1: Mechanics
This is the first of 10 volumes on Landaus „theoretical minimum“, an introduction to theoretical physics. The first book is on classical mechanics.

The English translation of the book starts with characterization of the man, they jerk him off a little. Not gonna get into history now, though.

WHAT

THE

FUCK

Can you get a gf while studying math and physics?

People can be very good at anything if they invest the time. I feel that way about myself and project that it can't be so hard for other to excel.
Some people who are good in their speciality don't impress me. I think it's admirable if they have discipline, though. I think it's cool if they found what they like.
I can't know how other brains work. I know I'm smart and I know there are some guys who I can work with well or who I can ask things about certain topics and they know their stuff.
I'm 31 now, studied physics to a PhD. My first response to that question was
>the guys who solved all problems super fast at uni do some stupid consulting shit now - the raw speed/intelligence doesn't mean much. It's often not used for anything outstanding
On a tangent, and maybe along those lines,
Grothendieck wrote about smart people here

Some coding golf for you.

In the language of your choice, write a function mapping a string s to a string r describing it, as in the following example:
s = "aaaaabbbbccccccaaaaaaa"
r = "5a4b6c7a"

Saw this on a Python community corner of the web, where one concise but arguably obscure solution was

import re
s = 'aaaaabbbbccccccaaaaaaa'
print ''.join(str(len(c)) + c[0] for c in [m.group(0) for m in re.finditer(r"(\w)\1*", s)])

Doubt it. The learning curve for this is too steep and it's too far removed from problems people know understand.
Proving stuff like Beaz conjecture and whatnot that only exists because this field (formulation) exists ... nobody cares for that

That's as far as my perspective goes and why I'm interested in "interesting" (for many people) problems. If n-cats help with with approaching stuff like this, that's cool, because algebra is a clean thing.
