i've had pages of that hanging in my classroom for 4 years.

tnf, have you ever seen the 1971 video "Protein Synthesis: An epic on the cellular level"?
I just saw it a couple weeks ago...absolutely crazy. It blew my mind like only a drug induced orgy of biochemists can.

About the only thing I do remember from my 8th grade science class. :icon14:

haven't seen that one. might have to look it up.werldhed wrote:tnf, have you ever seen the 1971 video "Protein Synthesis: An epic on the cellular level"?

I'm in the process of ordering Richard Dawkin's DVD version of the Ancestor's Tale. Great stuff.

It's great. It's about 15 minutes long and introduced by Paul Berg (iirc). If you can find it you should check it out.

nice video - i'm almost certain i saw it about 15 years ago at some disney land type place or something.
reminds me of the question about folding a thin sheet of paper in half, 100 times.
the resultant thickness will be about the radius of the universe (14 billion lightyears)

...and I was hoping for exponents. :icon8:

lawl. we watched this in my astronomy class. never knew the name of it though

Cool clip. Sucks the quality is so low on google because I hadn't seen it before.

Chuck Norris did that once. He could have folded it again but it would have defied comprehension.[xeno]Julios wrote:nice video - i'm almost certain i saw it about 15 years ago at some disney land type place or something.

I don't get it, how long is the sheet exactly?[xeno]Julios wrote:nice video - i'm almost certain i saw it about 15 years ago at some disney land type place or something.

You know how you can only fold a regular piece of paper several times before it becomes unfoldable? Something a long these lines is what I think xeno is talking about.
Since your doubling the height every fold?

Even if I tripled the height with every fold, if the piece of paper was 0.1mm thick, 0.1*100³=100m. If it was 1mm thick (that is one fucking thick piece of paper), it would be 1km.

isnt it more like 3^100 (or 2^100 in julios's case)? or maybe im mistaken?ToxicBug wrote:Even if I tripled the height with every fold, if the piece of paper was 0.1mm thick, 0.1*100³=100m. If it was 1mm thick (that is one fucking thick piece of paper), it would be 1km.

Sort of, but it doesn't have anything to do with being ubable to fold in half. It's all about doubling the thickness each time.
Pick an arbitrary number for the width of paper... say 0.000001 meters. Multiply that by 2^100 and that's the thickness of your result, in meters.
edit: oops...meant to be directed at Bluegene
edit2: Chupacabra has it right

I remember seeing it at the [Ontario] Science Centre when I was little, so that's probably what you're thinking of.[xeno]Julios wrote:nice video - i'm almost certain i saw it about 15 years ago at some disney land type place or something.
