The so called -1st (Minus First) law of thermodynamics, I believe states that information cannot be destroyed, or something along those lines. Does anyone know where I can read more about it? I think I've heard Dr. Leonard Susskind talk about it but it's been hard to find the video or any other...

Of all the stars in our galaxy, how much of them belong to clusters?? Is our sun rare in terms of not belonging to any cluster? I can't find any sources on that

From my understanding v is the velocity of the particles in the field, but doesn't this velocity exist because there is an electric field? how can you have v but no E?

I have some confusion about the Lorentz force. First of all, I found that there are two equations for the Lorentz force: one of them is F = qE + qv × B , and the other one is just F = qv × B . What's the difference between them and how do you know which one to use? My other question is: Is the...

What is the occurrence rate of planets? I'm not talking about earth-like planets, but any planet in general. I can't find a source that examines this number, all I can find is the average number of earth-like planets. Can anyone lead me to a useful paper/source? Thanks in advance

I think quantum computers have the potential to be humanities next biggest revolution

Thanks, that's very useful

I'm looking for journals/publications for last year's discovery of a star devoured by a black hole https://hub.jhu.edu/2015/11/26/black-hole-eats-a-star/ But I don't know where to look, the incident/object is not given a specific name in the article, and I need more detailed information about...

Yes, I understand that in this type of problem the projectile is moving in two dimensions, so we use x for motion in the horizontal and y for the motion in the vertical direction, but not sure why horizontal is always associated with cos and vertical is associated with sin in this problem

When solving a problem about shooting a cannon ball, why is the velocity in the x direction multiplied by cos and velocity in the y (vertical) direction multiplied by sin? like in the last example here...

When electrons produce photons in accelerators what is the mechanism called? and who was the first to do it?

Yes to me personally those are physics related. So is it easy to get a job like that in those departments? I don't care whether my job is researcher or technician or engineer, any of that is ok, and as long as the pay is reasonable (to me reasonable is anything above 55k)

Is it really that hard to find a physics related job with a physics B.S ? In this site...

Is there a short path to becoming a nuclear engineer if you have a B.S in physics? Can you get into grad school and specialize in nuclear engineering?

I have an equation that looks like At, r = Aφ, r If I know that Aφ = r4 , then how do I find At ? I believe that the above equation is equivalent to: ∂/∂r (At) = ∂/∂r (Aφ) , correct? Then substitute the value Aφ and we have ∂/∂r (At) = ∂/∂r (r4) And then to get At I take the integral on...
