Whats that then? Looks like top represent cell division and bottom effect on culture size?
Not sure, I do psychology me (cognitive mostly)

Or something smaller?

but it was contained in a pan that had no nucleation sites, would it bubble?
I read a book about the formation of snowflakes, it were dead interesting and had lots of pretty picture, that's nucleation as well innit?

It's not about boiling water and shit
It's about turning something that has the properties of a bag of flour for example to those of a bag of sugar... size enlargement and shit :D

and boiling and freezing are examples. If you cool pure water below freezing in a very clean container, then there are no sites for crystals to nucleate, so it becomes a supercooled liquid. If you then drop a seed particle in there, it will freeze out from that almost instantly.

but Im investigating it in granulation and the effect it has on the size enlargement process. Basically for pharmaceutical powders in drug making :D

Does that mean superheated water is possible? Or only under pressure?
I like the idea of dropping a grain of sand into superheated water and watching evaporate instantly in a poof of steam :)
I love science me

In fact you have to be careful when heating water in a microwave, if you're very unlucky it can become superheated. Then when you stick a spoon in to stir it, it'll boil explosively.

Nucleation does pop up in all sorts of places, I'm studying Materials Science and it always seems to be the explanation for something. The best demonstration we had involved champagne, and how to pour it without getting too much foam on top. (And then drink it of course!)

Might need a really pure, and free from stray dust, atmosphere though.
Adding pasta to really hot water gets damn close to full evaporation.

saw the example of co2 from soft drinks nucleating when pressure is released from the can.
Also super heated water in low pressure nucleates, but I think I get it, smaller stuff turning into bigger lumps of stuff :-D

making powders tabletable and getting the desired properties like size distribution and dissolution and shit like that....

that, given the right level of viscosity, time travel is possible?

Time to start whoring my just-finished topical swine-flu-related Mort animation, before it stops being topical.
Flash version: www.morttheostrich.com/pig_flu.htm

It's only about a minute long.

I'd like to suggest you increase the volume of the speaky bits :)
