Chemistry — Cooler Than Absolute Zero! Here’s a look at the remarkable properties of ten of the periodic table’s elements. The first on our list was hailed as the philosophers’ stone when it was discovered. 1.

"Exactly what makes a fermion a fermion is a bit complicated, but suffice it to say that fermions are all the particles that deal with matter. So what about the last group of elementary particles, the ones that don't deal with matter? These are the bosons, and they deal with the fundamental forces of the universe."

Chemistry Techniques – Titration Click to enlarge Anyone who’s studied chemistry will be overly familiar with titrations. It’s an analytical technique that can be used to find the concentration of a solution (the amount of a solute dissolved in it). I put this graphic together primarily to remind my A level students of some of the key aspects of titrations, but as well as being a handy guide for them, it’s a useful introduction to the technique for non-chemists too! Students are usually introduced to titrations in the context of reactions between acids and alkalis.
