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

Ringold talks about the fundamental differences between sole entrepreneurship in the academic setting versus entrepreneurship in an industry setting: a change in dynamics from a sole activity, to teamwork from different disciplines to solve fundamental problems. Industry has learned this long before the academic environment - that you need to bring people together from various industries and disciplines, with different skill sets to solve ...more

Professor Mazzotta continues his discussion of the Heaven of the Sun (Paradise X-IV), where the earthly disputes between the Franciscan and Dominican orders give way to mutual praise. The tribute St. Thomas pays to the founder of the Franciscan order (Paradise XI) is repaid by St. Bonaventure through his homage to St. Dominic (Paradise XII). The chiasmic structure of these cantos is reinforced by the presence of Nathan and Joachim of Flora...more

In this lecture, Professor Kagan continues to discuss the constitution of Athens. In particular, he explores the judicial workings of Athens. He describes in detail the effort of the Athenians to create a system of justice that would not only minimize tampering, in order to insure justice, but also maximize citizen participation. After this discussion, Professor Kagan comments on the role of women in Athens by looking at two types of sourc...more

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

It is important that chemists agree on notation and nomenclature in order to communicate molecular constitution and configuration. It is best when a diagram is as faithful as possible to the 3-dimensional shape of a molecule, but the conventional Fischer projection, which has been indispensable in understanding sugar configurations for over a century, involves highly distorted bonds. Ambiguity in diagrams or words has led to multibillion-d...more

It is important to use time to get deep expertise, Khosla notes. You need to go much deeper in understanding technology--a bachelor's degree is not enough and will be irrelevant in another 10 years. If you have a goal of entrepreneurship in mind, you must go deep in an expertise in order to advance your career.

Dell describes the PC industry today as a jump ball environment where no company can stay in a strong position for long. The development of wireless networks, miniaturization, and the influence of the internet has changed the competitive landscape of the industry, he says. One of the biggest threats is the changing computing model. To combat this threat, Dell, Inc. is focused on online servers and storage, new online devices, and anticipat...more

Hawkins talks on the importance and inevitability of portablity. With portability comes small size, low cost, simplicity and the need for less power. With wireless networks on their way to becoming very inexpensive, Hawkins envisions a T1 line with high horse power and large memory in the pocket! The need for portability will make the item in your pocket the center of your universe, he says. He notes that there will be obstacles, but belie...more
