The energy stored in chemical bonds pales next to the energy holding atomic nuclei together. Look back to the gradual unlocking of the secrets of the nucleus, the discovery of radiation emanating from elements such as uranium, and the eventual harnessing of this phenomenon for weapons, electrical power, and medical treatments.

Turn from synthetic polymers to biopolymers - those that occur naturally. Focus on polysaccharides, nucleic acids, and proteins (including a special class of proteins, enzymes). Discover that living systems exercise a level of control over the synthesis of these polymers that no chemist could ever hope to achieve in the lab.

Transition to the other side of the visible spectrum and discover how infrared spectroscopy provides chemists with different information about structures. In doing so, you'll come to see molecular structures in a new light: not as rigid constructs but as dynamic, vibrating frameworks with bonds that can stretch and bend.

Revisit the nuclear energy binding curve, noting that most elements lighter than iron can release energy by fusing together. This is an even more energetic reaction than fission, and it is what powers the sun. Follow the development of fusion weapons and the so-far-unrealized dream of fusion reactors.

How do organic chemists actually prove the behavior of molecules and chemical structures you've learned about in the preceding lectures? The answer: spectroscopy, which entails the observation of the interaction between matter and light. In the first of several lectures on the topic, focus specifically on observations made with the UV-visible spectrum.

Chromatography - in which partitioning between stationary and mobile phases leads to predictable rates of movement for compounds - is one of the most powerful separation techniques ever developed. And, when done properly, it allows chemists to isolate almost anything they can imagine. Witness a technique at the core of Professor Davis's laboratory experience.

Make sense of a crucial concept in organic chemistry: the handedness of molecules, or, as chemists call it, "chirality." Topics include the definition of chiral tetrahedral centers; the creation of stereoisomer sets via inversion of handedness; and intriguing examples of stereoisomers (including enantiomers and double-bonded stereoisomers) and their unique chiral centers.
