Atoms
Part 1. Professor Al-Khalili takes us from the discovery of the atom to the development of quantum mechanics.
Part 2. This episode tackles world-changing discoveries such as radioactivity, the Atom Bomb and the Big Bang, and tries to answer the biggest questions of all - why are we here and how were we made?
Part 3. Al-Khalili discovers that there might be parallel universes in which different versions of us exist, and finds out that empty space isn’t empty at all, but seething with activity.

Actually i take that back, it's still a google video...seems to work ok for me though.

You can watch a more stable version of this at quicksilverscreen.com but i much prefer this site in general.

That would be like trying to fit a few Boeing 777's on top a mosquito, or something of that order...
reply | permalinkElectrons are extremely*extremely*extremely small... if not smaller.
If the nucleus of an atom would have about a 1cm diameter, the electron would be thinner than a hair, and would "orbit" about two kilometers away from it.
A nanothingie contains quite a large quantity of atoms, depending... even its speedometer would still be far to big.

I'm not sure about gold, but there's a remaining star core that turned out to be a huge diamond.

We could build them out of strings? *Winks*

jenx- Electrons are subatomic (smaller than atoms). Atoms make up all matter - including nanoscale technology. It's like you're saying let's build a car out of lincoln logs and have it drive on a single splinter from one lincoln log. It makes no sense. Nanorobotics is still being researched anyhow. When they make something on this scale it is molecular in size (made up of multiple atoms). There is no such thing as subatomic robotics - the two words don't even make sense together.

If you can't know the position and the speed of an atom at the same time, what if scientists created nano-bots to ride electrons and report the speed and position of the atoms they are riding on?

It took me 3hours in watching this vid but I got a technique. 1st let the vid play while waiting the grey line filled-in the entire bar then that is the time you can watch it in full w/out interuptions
