Why does a snowflake have a 6 sided symmetry, Why is that they all seem to be different. What causes the distinctive geometries and very importantly, how does each of the 6 sides communicate to the other sides what they should look like.
@markakroll Well, as far as I can recall, it has to do with the way water hydrogen bonds with other water molecules in the solid state(usually), they form a hexagon, and this shows up as everything having to do with crystalline water having six sides. It also has to do with the reason water expands on freezing. Water is one of the most interesting molecules yet, in my opinion, so simple, yet such a complicated background. Hope this helps!:)
The new toy shows the cubic crystal structure of halide (sodium chloride) and galena (lead sulfide) or even pyrite - fool's gold (iron sulfide). Any mineral with a cubic or octahedral crystal. Useful when teaching about ionic bonds.
The mark of the genius is in buying the dog toy first and then figuring out how to fit it into his lectures. Simple pleasures seem to amuse great minds, too.

i think i have a toy which makes sounds like wiggly giggly... it's a tube with some kind of little sound producing device in it... it's not electronical though...i don't really know it for sure.. coz it's like when i was 10 or sumtin... n i also like the sound of it..
It's clear that he has demonstrated a need. The molecule model kits that students use to make molecules with need to make silly noises! Seriously, that'd be neat. :)
Lol professor do you even have a dog or do you just walking around in dog shops hoping that you'll find a dog toy that looks like a molecule
