Enlisting the Help of TNL

So I have a final coming up in my physics class, which involves me giving some sort of presentation on a physics related problem.

"The main requirement is that you explore and research ANYTHING in physics that you find interesting. This could be a question you want to answer, to something you want to try and build, to an experiment you want to design for the class, to classic research and presentation, to ?????"

This basically leaves the door wide open, but the problem is that I can't think of a suitable topic. I've been thinking of these 3 ideas, but I don't know how well either of them would fly by....

Quantum Physics
Cold Fusion
Fusion Propulsion

I'm still trying desperately to think of any other topics that would make a good presentation. I need to speak for 20-30 minutes about whatever it is that I choose, so it can't be something too basic. Do any of you have any ideas as to what might be a good choice? Thanks a lot.

Your mom.

A 30 minute non-craptastic speech? Good luck with that

If you like music, or play any musical instruments, sound radiation and acoustics are always fun topics. I heard a nice one on acoustics a long time ago.

That's definately going on my list of potential ideas.

If your Hummer jumped off the edge of a 100 foot cliff at 60 mph what would the force of impact be as it hit the ground? Make it a show and tell project.

You're so fucking creative. Get the fuck out of my thread unless you have something useful to say.

Napalm. I would do quatum physics and compare it too the theory of evolution. Base the presentation on how quantum physics shows that everything dies/decays and how evolution says that everything gets better.

Vf^2 - Vo^2 = 2ad
Vf^2 = 2ad
Vf^2 = 2(9.8 m/s)(30.4 m)
Vf = 24.4 m/s

KE = .5mv^2
KE = .5(3810 kg)(24.4 m/s)^2

KE = 1.13 x 10^3 kJ.

Yes?

Sigh... evolution says genetic traits that improve survivability become more expressed over generations. That is not the same as "better".
