After discussing the classic determination of the heat of atomization of graphite by Chupka and Inghram, the values of bond dissociation energies, and the utility of average bond energies, the lecture focuses on understanding equilibrium and rate processes through statistical mechanics. The Boltzmann factor favors minimal energy in order to provide the largest number of different arrangements of "bits" of energy. The slippery concept of di...more

Professor Diamond's review of the lymphatic system continues with the lymphatic vessels and lymph. Professor Diamond compares lymphatic vessels to the cardiovascular system and notes the differences in structure. Next, Professor Diamond defines lymph (tissue fluid) and its composition and function. The movement of lymph is also discussed, and again, this is compared to the movement of blood through the body. The absorption of fat by the ve...more

In this lecture, Professor Diamond continues her discussion of the liver before moving on to the pancreas and hematology. She first describes how the liver is composed of cells called hepatocytes organized into lobules with triads, which each contain a branch of the hepatic artery, a branch of the hepatic portal vein, and a bile duct. She then reviews the functions of the liver, including supporting digestion through bile production, dev...more

Professor McBride uses this lecture to show that covalent bonding depends primarily on two factors: orbital overlap and energy-match. First he discusses how overlap depends on hybridization; then how bond strength depends on the number of shared electrons. In this way quantum mechanics shows that Coulomb's law answers Newton's query about what "makes the Particles of Bodies stick together by very strong Attractions." Energy mismatch betwee...more

In this lecture, Professor Diamond wraps up her discussion of the nervous system and moves on to the urinary system, beginning with the kidney. She concludes her discussion of the nervous system by describing the cochlea and diagramming its structure, and she indicates how cilia (hair cells) respond to and transmit information about vibrations in the fluid inside the cochlea. Professor Diamond then diagrams the constituents of the urinar...more

Professor Freeman discusses what it meant to be a British colonist in America in the eighteenth century. She explains how American colonists had deep bonds of tradition and culture with Great Britain. She argues that, as British colonists with a strong sense of their British liberties, settlers in America valued their liberties above all else. She also explains that many Americans had a sense of inferiority when they compared their colonia...more

In this lecture, Professor Paul Fry examines acts of reading and interpretation by way of the theory of hermeneutics. The origins of hermeneutic thought are traced through Western literature. The mechanics of hermeneutics, including the idea of a hermeneutic circle, are explored in detail with reference to the works of Hans-George Gadamer, Martin Heidegger, and E. D. Hirsch. Particular attention is paid to the emergence of concepts of "his...more

This lecture is devoted to the electron diffraction experiment of 1927, where the wavelike nature of electron beams was experimentally established, thus supporting an underlying principle of quantum mechanics. Professor Sylvia Ceyer discusses how to calculate λ from θ, de Broglie wavelength, and concludes with Schrodinger's equation of motion for matter waves.

Turner talks about how the James Bond character was done in the third person in the game and his style and control comes from the mechanics of how he moves. He is always the master of his environment, she says.

Professor Barry Sharpless of Scripps describes the Nobel-prizewinning development of titanium-based catalysts for stereoselective oxidation, the mechanism of their reactions, and their use in preparing esomeprazole. Conformational energy of cyclic alkanes illustrates the use of molecular mechanics.

May 19, 2009 - Leonard Susskind lectures on a new class of systems, magnetic systems. He goes on to talk about mean field approximations of molecules in multidimensional lattice systems.
