Our study suggests that fitness of invasive zebra mussels is not constrained by nutrient stoichiometry which is likely to be important for their proliferation in novel ecosystems.
The following article makes no attempt to be a 20-minute Chem 101 crash course for the perplexed, but, it is hoped, should at least provide you with counter-ammunition the next time someone corners you at a party and starts dropping terms such as stoichiometry as the temperature of your beer rises slowly but inexorably from cellar to attic.
One lecturer admitted to cribbing a definition of stoichiometry from Wikipedia.
Also, much of what we take away from secondary education is not specific facts or processes I don't know about you but I'd have some major difficulty solving a stoichiometry problem now, but ratherÂhowÂto think.

So the thought hit me that it might be interesting to ponder the stoichiometry - the math behind the chemistry - of the TBTF rebalancing issue.
Berkeley used to have an experiment in which Chem 1 students prepared cuprous sulfide and determined its stoichiometry ratio of Cu:S.
Students, expecting stoichiometry, nudged their results toward a stoichiometric result, with most rounding up to 2:1, but some rounding down to 1:1.
This and the stoichiometry of the tetramer implied a unit of structure in chromatin based on two each of the four histones, or an (H2A) 2 (H2B) 2 (H3) 2 (H4) 2 octamer.
From tools like a huge stopwatch applet to online, video-enhanced games about stoichiometry to an interactive model ripple pool, it is awesome.
