The Big Bang created the physical universe. Of course life is part of this physical universe, but the immediate building blocks of life are chemicals. Before the Big Bang, words such as “time” had no meaning, but even in the first few minutes there could be no chemistry since there were no atoms. The nuclei of some of the lighter elements formed within minutes, atoms some time later, and elements heavier than lithium were forged in the sup...more

The movement of matter and energy around the planet is very important, and its study draws on geology, and meterology in addition to chemistry. Energy tends to flow upwards from plantlike producers to herbivores to carnivores before being decomposed by detritovores and cycling back into energy usable by producers, in addition to the photosynthesis or chemosynthesis used by producers to produce energy. Like energy, compounds vital to life s...more

How hormones, phermones and bonding chemicals connect with the experiences of sexual arousal and romantic love. To what extent are we victims of our brain chemistry and neural processes? What are the evolutionary origins and adaptive values of "falling in love"?

Ringold talks about the idea behind and the history of combinatorial chemistry to accelerate the process of drug discovery. He then talks about a technology that was invented for a different purpose but was eventually applied to the specific problem of broadly monitoring the expression of gene sequences giving birth to Affymetrix.

Worthington talks about how Fluidigm relied on two assets to help them recruit top talent: breakthrough technology and chemistry. Obviously, the technology was a big draw for many people to come to Fluidigm, he says. Chemistry was not as obvious an asset. Worthington got along well and developed strong relationships with many individuals that helped Fluidigm to recruit the top talent.
