I am doing a presentation on anything in physics of my choice for my A level physics class. I was wondering if any of you would have any suggestions?Cheers

What is an A level physics class and what is your presentation supposed to be on?

It is year 12 of school, after high school in the american system I think... Literally, it can be anything of my choice within physics.

I did a similar thing for my Year 13 research project, on superfluids. I found quite a lot of interesting stuff on the Internet about superfluids, and its mostly reasonably easy to explain without too much maths. Plus, there a few nice pictures.

When you cool He-3 or 4 down to a couple of K, they turn to fluids, but the fluids have some interesting properties - frictionless flow, very high adhesion to surfaces, quantum vorticing. That's all I can remember off the top of my head, but there's loads more out there.

What is quantum vorticing? Thanks for the idea, I think that I will look into it, it sounds really interesting.

Quantum vorticing is a property of rotating superfluids. Due to a component of the flow of superfluid having to be constant, vortices or whirlpools appear in the superfluid, in a regular array, with the number of vortices dependent upon the speed of rotation.
This is one of the articles I used in my research. I by no means claim to understand most of it, but I think there was some useful stuff in there.
Another site I used as the starting point for my research - it should give you some ideas about what to search on.

Thanks man, it is really useful. :D
