How Long Is A Piece Of String?

Please share your thoughts on the documentary that you've just seen. Love it? Hate it? The best documentaries are the ones that stimulate debate within yourself. Share your thoughts!
Fairly good doc. The best bits were at the end where quantum mechanics in nature was discussed. I definitely want a ruler that measures in ancient units now too. lol
I liked this documentary quite a bit.
Seth Lloyd is now my new favorite scientist.
very good. I kept expecting to here some conjecture on Zeno's Paradox's, and was pleasently surprised when they avoided it.
I like these doc's that explain complex concepts in simple terms. But its a little disheartening when I still can't quite grasp it
great documentary about the basic measurement
giving the idea,
THERE ALWAYS A PLENTY OF SPACE AT THE BOTTOM
Although infinity "both ways" raises some serious issues.
If the space between me and the nearest wall is infinite then how the hell am I able to reach it?
Interesting subject, really makes you think about what everything is made out of…
The guy is not really funny though, at times he comes off as a little dense.
shrodinger was autrian ;)
This is pretty good for a documentary aimed at laypeople, but one thing bothers me no end. Electrons do not ORBIT the nucleus of an atom. That is the bohr model of the atom and was proven wrong in the 1920s, but most people still think it's true because a lot of teachers – like the physics teacher in this doco who agreed that they do orbit the nucleus – think that it's simpler and easier to understand, as if laypeople are too dumb to understand what's actually going on, and other teachers were taught the old model and don't themselves know of the new one. When drawn, btw, the new model looks more like this -> http://web.rollins.edu/~jsiry/atom-quantum.jpg. The electrons zoom around, being both particles and waves, spending most of their time in those dumbbell shaped spaces, which are the orbitals. The highest energy electrons, rather than those on the outermost orbit in the bohr model, are the valence electrons.
i agree with that whole heartedly. and this is a common thing with most docs. they tend to be made by people who mean well, and even have visionary intentions, but sometimes the simple facts fall through, however well informed or researched they are. its probably going to be that way until brad pitt, or megan fox signs on to host one or two (you know…budget). its kind of sad, really. these kinds of educational, and entertaining docs are almost the food for the intellectual masses. its what build, and bolsters the ranks of the scientifically interested.
the guy at the end his laugh is sooo aweful
Video doesn’t work anymore
