What are your favorite physics things?

Mine would be Maxwells Equations or the Theory of Analytical Space-Time in Quantum Mechanics. I'm so excited to be taking Physics next year! High-fives, anyone?

I'm personally fond of Special and General Relativity. It is so difficult to learn and master, and yet they are profoundly elegant in their description of the universe. Much of modern astronomy, astrophysics, and cosmology comes directly from those equations.

They also are why we have satellite communications and GPS systems.

As a Chemical Engineer, I'm required to love the Navier-Stokes equations.

The second law of thermodynamics - especially entropy.

You down with entropy?

Well in concept waves, quantum physics, and cosmology is quite interesting. In practice, when you have to work with the mathematics, it's quite horrible. There's math involved with cosmology that I don't have the slightest idea how to work with.

The Newtonian stuff, on the other hand, is wonderful to work with and I quite happily spent an entire summer working problems for at least 5 hours a day.

Lower division optics and E&M are also quite fun. Thermo, not so much.

Here is a tip. There is a book called "Conceptual Physics" which might be of a lot of help.

The nature of consciousness. 'Cause we know nowt about it.

Thanks!

i'm familiar with inert gas lasers and how they 'work'. i assembled my first he-ne laser that used a 12 volt battery to function. i also have a 10mw he-ne and a 100mw argon/ air cooled.

was murdered and later committed suicide, so being dead a few times and receiving multiple head injuries has limited my continuing work with lasers.

i was aware of low powered laser pointers many years ago, but just saw a listing for a 1 watt hand held 532nm
diode laser. thats serious power, and i am ignorant of just exactly how solid state lasers function.

if one of you brainiacs could clue me in, i would be grateful.

Wholly fascinated by gravitational singularities and redshift.
