Physics videos!
« on: September 24, 2012, 03:25:52 PM »
So.
it's too bad that i love the podcasting format so much,
because physics is one of those things that is better explained visually.

I'm gonna use this thread to post fun physics videos I find online.


this one's nice. it's a little elementary, and you don't learn much.
but you do get to SEE SOMETHING WONDERFUL.
and that's pretty fantastic in my book.

also i like the french in it.

It's AMAZING! I love the dry ice geyser at the end, it's beautiful!

yeah! so fun.

in the spring, when we did the episode on... superfluids... i think. our guest asked how you go about getting something that cold.

and we had no idea.

as far as my education goes... you follow someone out to the big cylinder of liquid nitrogen with a big dewar... and then they fill it up and you try not to jostle them.

 :(

This is the best thing I've seen in a long time. Those dolphins are AMAAAAAAAAZINGGG!!!!!
And the belugas, and that friking huge ring by the Humpback Whale!!

Oh, my, I love cetaceans. They are my favourite animals. They are beautiful, graceful and uncomfortably intelligent. I sure hope some day we could invent a device to communicate with this guys. They seem so bright, like they have an entirely complicated subjective experience in their brains.


I also enjoyed the toroidal cloud at 2:53. Not much of a fan of nuclear weapons, though.

Niiiiceee.

Have you seen the MIT lectures by Walter Lewin? They're awesome. He does a lot of demonstrations, like shooting cans with rifles to explain pressure, but also has rigour in his maths.
His whole course on Physics I is on youtube:

This is chemistry rather than physics, but it's still cool:

That guy draws the best dotted lines. How does he do it!?

Yeah, I also noticed that and was puzzled. I think he just draws with the chalk pointed in the direction of motion and that makes it do those "jumps". I need to try it sometimes to see how difficult it actually is.

I'm teaching on chalk boards a lot lately,
so i'm going to try tomorrow.

Yep, I was right.

One might need a little practice, though. Tell us how it went, Ben!

I had a teacher in high school who did that, and always wondered how he did it. Now I know!
Did I do, O CROM, did I as I said Id do? Good! I did.
