This lecture continues the discussion of the HOMO/LUMO view of chemical reactivity by focusing on ways of recognizing whether a particular HOMO should be unusually high in energy (basic), or a particular LUMO should be unusually low (acidic). The approach is illustrated with BH3, which is both acidic and basic and thus dimerizes by forming unusual "Y" bonds. The low LUMOs that make both HF and CH3F acidic are analyzed and compared...more

After mentioning some legal implications of chirality, the discussion of configuration concludes using esomeprazole as an example of three general methods for producing single enantiomers. Conformational isomerism is more subtle because isomers differ only by rotation about single bonds, which requires careful physico-chemical consideration of energies and their relation to equilibrium and rate constants. Conformations have their own...more

Fundraising is simply an energy transfer to further your projects, says entrepreneur and X PRIZE founder Peter Diamandis. It's also the most critical skill an entrepreneur can have. When trying to raise funds, it's critical to remember that you have to ask for what you want, and that you have to give others the opportunity to be involved. And, says Diamandis, never walk away from a potential funder without something; whether it's dollars,...more

This lecture begins a series describing the development of organic chemistry in chronological order, beginning with the father of modern chemistry, Lavoisier. The focus is to understand the logic of the development of modern theory, technique and nomenclature so as to use them more effectively. Chemistry begins before Lavoisier's "Chemical Revolution," with the practice of ancient technology and alchemy, and with discoveries like those of...more

Find what you have a passion for and find a company that represents that, says Raikes. Life is too short to focus on money. Interviewers look for three things: high energy, high horse power, and the ability to get things done. It is nice to have relevant experience, but it is more important to be really passionate and willing to learn quickly, he adds.

Professor Kleiner features the architecture of Augustus' successors, the Julio-Claudian emperors, whose dynasty lasted half a century (A.D. 14-68). She first presents Tiberius' magnificent Villa Jovis on the Island of Capri and an underground basilica in Rome used by members of a secret Neo-Pythagorean cult. She then turns to the eccentric architecture of Claudius, a return to masonry building techniques and a unique combination of...more

March 4, 2009, Richard Morse states that coal is the largest growing source of energy and that regulation and policy are beginning to play a larger role in the economy of coal power. Morse also discusses the heavy reliance on coal by developing countries and the need to understand and evaluate all mitigation options.

Waves are discussed in further detail. Basic properties of the waves such as velocity, energy, intensity, and frequency are discussed through a variety of examples. The second half of the lecture deals specifically with superposition of waves. Constructive and destructive interferences are defined and discussed.

Work by Wöhler and Liebig on benzaldehyde inspired a general theory of organic chemistry focusing on so-called radicals, collections of atoms which appeared to behave as elements and persist unchanged through organic reactions. Liebig's French rival, Dumas, temporarily advocated radicals, but converted to the competing theory of types which could accommodate substitution reactions. These decades teach more about the psychology, sociology,...more
