Chemistry
Chemistry is the scientific discipline involved with compounds composed of atoms, i.e. elements, and molecules, i.e. combinations of atoms: their composition, structure, properties, behavior and the changes they undergo during a reaction with other compounds. Chemistry addresses topics such as how atoms and molecules interact via chemical bonds to form new chemical compounds. There are four types of chemical bonds: covalent bonds, in which compounds share one or more electron(s); ionic bonds, in which a compound donates one or more electrons to another compound to produce ions (cations and anions); hydrogen bonds; and Van der Waals force bonds.

The Joker: You IDIOT! You made me. Remember? You dropped me into that vat of chemicals. That wasn't easy to get over, and don't think that I didn't try.

Chemistry
The alchemical tradition assumes that every physical art or science is a body of knowledge which exists only because it is ensouled by invisible powers and processes. Physical chemistry, as it is practiced in the modern world, is concerned principally with pharmaceutical or industrial research projects. It is confined within the boundaries of an all-pervading materialism, which binds labor to the advancement of physical objectives.

We can no more have exact religious thinking without theology, than exact mensuration and astronomy without mathematics, or exact iron-making without chemistry,

Photovoltaic (PV) systems that harness the Sun's virtually limitless supply of energy are now visible in limited locations across Europe. A new open-source simulation platform will foster lower costs and enhanced performance for mass market uptake.
