Di-hydrogen Monoxide

Mathematician: 3 is a prime, 5 is a prime, 7 is a prime, and by induction - every odd integer higher than 2 is a prime.
Physicist: 3 is a prime, 5 is a prime, 7 is a prime, 9 is an experimental error, 11 is a prime. Just to be sure, try several randomly chosen numbers: 17 is a prime, 23 is a prime...
Engineer: 3 is a prime, 5 is a prime, 7 is a prime, 9 is an approximation to a prime, 11 is a prime,...
Programmer (reading the output on the screen): 3 is a prime, 3 is a prime, 3 a is prime, 3 is a prime....
Biologist: 3 is a prime, 5 is a prime, 7 is a prime, 9 -- results have not arrived yet,...
Psychologist: 3 is a prime, 5 is a prime, 7 is a prime, 9 is a prime but tries to suppress it,...
Chemist (or Dan Quayle): What's a prime?


A mathematician belives nothing until it is proven
A physicist believes everything until it is proven wrong
A chemist doesn't care
biologist doesn't understand the question.

Is that the same Randall Munroe that does XKCD?

HA, it's a fraction of a cent.

technicly because the bonds of water are covalent its just hydrogen oxide.

The nature of the bonds (beyond being existant) has no bearing on the naming procedure for a molecule

yes it does you only add prefixes onto ionic bonds. Covalent bonds do not get the prefixes.

I think it's the other way around, isn't it?

oh shit it might be.

I have no idea.
I just save the image because it was amusing.
