On Amazon today this image caught my eye:
Pretty interesting organic molecule, I thought. It looks kind of familiar. I resized and sharpened the atomic drawing to make it easier to see:
Some of the N and H characters are hard to distinguish if you don’t know any organic chemistry, but if you do it’s clear which is which.
Anyway here’s a caffeine molecule (unlike the Amazon drawing it doesn’t draw out all the carbons and hydrogens):
The molecule on Amazon isn’t shown complete, so there’s plausible deniability, but it sure looks like Amazon thinks caffeine is a “school essential” for K-12 students. I wonder if it works as well as ritalin.
For the last three months I’ve put a lot of heavy use into the The Joy Factory SmartSuit3 Stand/Case for the iPad. Even though I have the “white/silver” version, it’s showing almost no signs of wear or dirt after being used almost daily around the home and taken on over a dozens of flights. The magnetic wake/sleep feature works great with the latest iPad 3 and all the ports and jacks are easily accessible. Highly recommended.
