What list of basic concepts would be complete without a primer on polar and non-polar molecules? You'll recall that chemists live in a world made up of atoms and various assemblies and modifications thereof, which are, in turn, made up of protons, neutrons, and electrons. Protons (which have…
As promised at the end of my post on polar and non-polar molecules, here's a basic concepts post on intermolecular forces. Intermolecular forces are the forces between molecules, whereas intramolecular forces are those within molecules. (The bonds that hold the atoms in a molecule together are…
It may be Thanksgiving weekend here in the States, and fellow ScienceBloggers PZ and Ed may be getting sniping at each other over Larry Moran's rather intemperate comments. (Can't we all just get along, guys, at least for the holidays anyway?). Worse, this kerfluffle is threatening to suck in other…
Yesterday, I showed you a picture of 100,000 nearby galaxies, which made me feel small, even when we just look at our (relatively) local Universe. Today, let's go down to the other end of the spectrum. Electron microscopes have been around for a long time, and they've let us see some very advanced…
