Hey.....Im in Physics 1 regular and i was thinking of taking physics 1 honors. Is physics so much harder than chemistry or easier? I got a B in chemistry honors last year and a A in algebra 2 honors last year and i was wondering if it would be a good thing to take physics 1 honors this year? is physics even that hard?

Gell-Mann was looking for a common denomenator to the atomic zoo -- a common denominator of characteristics.
He found some (3) and didn't know what they really
were so he called them Quarks.
Later he found more, so he had 6.
Now each quark can have three varieties of colors:
"red", "blue" and "yellow".
Quark theory is not completed.
So, maybe somebody will find sexual quark in the future?

So what happens to the other photon? Since a black hole is a singularity from which "no information can escape", will we see a change in the state of the photon that is external to the black hole? Will that photon freeze in space? Does changing the state of the entangled external photon change of the state of the photon inside the black hole? How could it? If entangled photons get caught at the event horizon of a black hole, shouldn't there be big clusters of their entangled pairs floating about helplessly some distance from the black hole? Is this the "information" hawking says you can get out of a black hole?

to me , usage is mixing up. People sit on rockets to go to moon. No one sits on a missile. Fighter planes carry both rockets and missiles.

consider linear inelastic collision, we know:
momentum = mass x Velocity
Kinetic energy = 0.5 x mass x Velocity ^2
both directly proportional to velocity...if there is no loss in mass, velocity is the only way to reduce kinetic energy due to the inelastic collision.how can momentum remain the same yet kinetic energy gets reduced ( for the system of two colliding solids).
one case that comes to mind:
we bounce a golf ball between two walls in a room in space (vaccum inside and zero gravity). if Kinetic energy gets lost due to the inelastic collision then the velocity will eventully be 0 and the ball will stop...which means the momentum of the ball will be zero.the room istelf will have to be at rest since the bouncing between the two walls should cancel out given the momentum conservation laws...something is wrong in this picture I am just not sure what it is?
any advice is more than welcome.
thanks

A while ago I was watching TV (I can't for the life of me remember what I was watching, though) and they were talking to scientists.

The scientists explained that they can never know what caused the Big Bang because the farthest back their cameras could record was a billionth of a second after.

But in saying that, doesn't it mean that they found out a way to send video cameras back in time? If not, how is it possible to record the aftermath of the Big Bang?

Please provide website link in your answer. It must be a 100% online course, very basic Physics - like an introductory class. Accreditation not an issue - it is for employee understanding of general concepts for the workplace.

Thank you so much!

My guess is that it is the bonds between atoms in chemical compounds which vibrate and then these vibrating bonds then cause the whole molecule to vibrate, perhaps in complex ways if there are many inter-atomic bonds. Hence Brownian motion. But does this mean that the atoms in an inert noble gas do not vibrate? Does this difference exist and, if so, what consequences are there at the macroscopic level? Or have I got it all wrong? If so, then please give me the full story.
