When you were a kid, did anyone ever tell you that your head would explode if you hung upside down for too long? Well... they might have been on to something.

Dihydrogen monoxide (better know as water) is the key to nearly everything. It falls from the sky, makes up 60% of our bodies, and just about every chemical process related to life takes place with it or in it. Without it, none...

Beautiful Bonds: The World of Covalent and Metallic Solids

Covalent solids, also known as network solids, are materials with atoms bonded together in a continuous network by covalent bonds, resulting in large, rigid structures....
