Anyone taking physics?

I got a hella good formula sheet if anyone wants it. 4A which is the calc version of the basics, like forces, torque, pressure, momentum, density, blah.

It's pretty awesome, are you learning about kinematics right now?

I already learned everything about Physics that's in the SAT II, and much of the Feynman Lectures on Physics.

So far, we haven't learned anything real in class yet, it has only been the third day. I'm ready to get a 100 in this class.

Do you know how anal your professor is? If we forget the "hat" on i-hat or vector signs, or put vector signs on things that don't need them or use the wrong units we get mark offs, decently big ones too.

My last year's cheat sheet was two pages. Stuffed to the max.

Here it is, I didn't include all of Elasticity of a Solid as well as all of waves because it wouldn't fit.

We used all of these many times, at least three each besides terminal speed of a falling object.

I took that AP physics my freshman year. I'm taking it again, but now it's relitavistic physics. We went through a bunch of experiments on the constancy of the speed of light, in many different and wild ways (5 papers, ugh). Then he was like "Measure time in meters and distance in seconds" and I fell over. I appreciate what Einstein did more and more each day.

That sounds fucking awesome.

It is, but it sucks that I have to take it at self study. Quick basics:

interval^2 = (change in time)^2 - (change in distance)^2
c =299792458 m/s
1 m = 1/c s
1 s = c m

Using the speed of light as a conversion factor between distance and time, one can plug them into that form above, which is the basis of Lorentz geometry. This accounts for time dilation and and stretching, and establishes a common thread between all references frames, i.e. points of view.

Cool shit!  hocuspocus;

Yeah I remember doing that with sound, fuck who gives a shit about the small difference (assuming the distance is small.)

The kind of problems are so epic in scope. Like, "How much is a light wave deflected by passing the sun very close to the sun in straight-line travel," and "Two ships are firing bullets at each other using state-of-the-art detection technology using light flashes, they're going at v = .01c calculate this and that" or "Derive all this other cool shit" it comes into play more than you might think. The problems are so contrived, but they're so epic in scope that I feel a bit of thrill doing them.  giggle;

Can you export this sheet to a PDF or something? It doesn't work on the Mac version of Office or Apple Pages.
