You are currently the best thing to ever happen to Youtube.

Hey.. I just wanna ask u a question... How and Why does magnets repel and attract...

cool vids ... wish i had teachers like u at college

Please - cos you have the rare gift of explaining the obtuse/mind bending type stuff, I'd really love to see you explain phase entanglement and the non local universe. I never got the probability thing so well before I saw your video. The closest I (probably) came was the penguin thing in the BBC's Douglas Adams show. You really are a dear and it would mean so much to me. Maybe you could also explain for me the 'sidewalk astronomer's' views on the universe not expanding from a big bang, but being static, and recycling everything from the outer edges, and as he states, that the universe does indeed have edges. Or if that's distasteful to you, maybe a comparison of current belief vs his idea of the static universe recycling? Cheers.

PS: anything on the nature of time would be great too. Love the quote "time is what stops everything happening at once"...Or does it???

jlin91, I do intend to finish the relativity videos. I'm just a little busy right now. I've gotten myself on a few too many committees here at work. ;) I had hoped to do the next installment over New Year's, but alas, a big project came up. Now, I'm hoping April break will give me a chance. Video three already has a script, I just need to animate it.

.. just wondering.. are you ever guna finish the relativity videos? the first few were great!..

cool!

well, it's past new years. where is the video? I need this explained many times, and i think yours will be the icing on the cake that makes it stick.

Question for the republican candidates - in 18 seconds

noonscience, don't worry; the science videos are still coming. Life has just been getting in the way for a while. I'm hoping to turn out the next relativity video over new year's.
