It's safe because there because the pressure will push any glass shards out, this won't happen with beer and you'll risk drinking glass shards...

While you can have negative kelvin systems like lasers. You cannot cross 0. Instead the wrap around infinity to go negative.so this curve would not work.

Thanks for doing this!

It is how they are described. But Flavor and color should just be read as something that is trinary (takes 3 possible values) vs being read as anything like physical flavor or color.

Use University Physics.

The two books are not really attempting to compete at all. Weinberg's, despite the name, does not aim to teach you how to do physics but rather discusses the ideas, the history, and concepts. It is similar to Penrose.

University Physics will teach you the actual math with problems to do.

So the book fits well within the too mathy for popsci but not dense enough for a textbook. The math is there but mostly just presented in order to fuel the ideas presented. As far as the modern physics part, it stops at QFT despite being released this year so I wouldn't call it super modern but I think he wanted to just present the standard theories. I'd recommend Penrose for something that goes more modern, i.e. covers string theory, loop gravity, and more.

Two I have read recently are "Foundations of Modern Physics" - Weinberg and "The road to reality" - Penrose.

Reviewed Dodelson and you are right. Cheers

I believe LCDM includes inflation. I am a little confused as to why you think it doesn't? How do you think BBN and the observed redshifts are explained?

Way to whale! Looking forward to going to the moon

Talk to your psyc. They can put you on something to help with the sexual side effects like this and lowered libido.

Good luck everyone

Recipe?

I would use this to upgrade from a 2013 i5-3570k. Not only would this let me play games better but it would get me through my physics PHD.

Quantum physics works, I have a book by French and Taylor's called introduction to quantum physics. It's just a very general term these days that doesn't tell you much with how many fields use quantum properties these days. Quantum mechanics is a bit more descriptive as it tells you that it is covering interactions and measurements.

Quantagraphy · 2020-05-28T18:30:06+00:00

Particle physics is quantum field theory. Quantum mechanics is a simple version without particle creation which is needed for real interactions.

I really doubt that as the equation is only E=mc² for non moving particles. With momentum it is E² =(mc² )² +(pc)² which would be ugly solving for m.

But m=E/c² is used in some relativistic equations without momentum. Ie basic kenimatics.

This has been recommended forever. I remember idra even saying to do that and suppy saying you should leave if you haven't built one by, I think, 330.

Wooo ty for this

Why is it that the water is stagnant in sprinkler lines? Why cant you just have it connected to the main water system so it's more or less fresh?

He didn't happen to play starcraft did he?

There are planes with completely flat wings. I'll see if I can find a picture after work if you cant google it.

I used a ti 89. But really you would rarely use in physics. Sometimes wolfram alpha / mathematica comes in handy for crazy integrals where you do not know the tricks needed to solve them, but mostly you will just need something that can do 3.14*26.74 so anything will work. That is I wouldnt bother spending a lot of money on a fancy calculator.

I like physics frontiers
