Continuing the discussion of Lewis structures and chemical forces from the previous lecture, Professor McBride introduces the double-well potential of the ozone molecule and its structural equilibrium. The inability for inverse-square force laws to account for stable arrangements of charged particles is prescribed by Earnshaw's Theorem, which may be visualized by means of lines of force. J.J. Thomson circumvented Earnshaw's prohibition on ...more
Detecting fixed points in von neumann's simple random number generator. data structure revision. using trees. implementing a very simple tree. Talk about the anagram lab exercise. Improving the UNSW 89019 microprocessor. CISC and RISC design. Using memory segments to be able to address more memory. The bicycle wheel puzzle. Simulation - a neat and simple way to solve complicated problems when you can't be bothered to use/can't rely upon...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
This lecture asks whether it is possible to confirm the reality of bonds by seeing or feeling them. It first describes the work of "clairvoyant" charlatans from the beginning of the twentieth century, who claimed to "see" details of atomic and molecular structure, in order to discuss proper bases for scientific belief. It then shows that the molecular scale is not inconceivably small, and that Newton and Franklin performed simple experimen...more
Professor Shapiro explains the format and structure of the class during this opening session. He reviews the syllabus, and asks the central question of the course: What makes a government legitimate? He briefly explains the five ways to answer this question that he will focus on throughout the semester. The first three traditions are those of the Enlightenment: utilitarianism, Marxism, and social contract theory. The fourth and fifth overa...more
Professor Saltzman continues his discussion of biomedical imaging technology. Magnetic resonance imaging (MRI) is introduced as an alternate form of imaging, which does not use ionizing radiation yet can provide detailed structure of the body. Functional MRI (fMRI) has a different application from traditional MRI. It can be used to measure oxygen consumption (tissue metabolic rate), and is an important tool in deciphering brain function. T...more
Professor Marian Diamond. The functional anatomy of the human body as revealed by gross and microscopic examination. The Department of Integrative Biology offers a program of instruction that focuses on the integration of structure and function in the evolution of diverse biological systems. It investigates integration at all levels of organization from molecules to the biosphere, and in all taxa of organisms from viruses to higher plants...more
This lecture examines Book Four's depiction of Adam and Eve and the sexual politics of life in Eden. Seventeenth-century political theory, particularly the work of Thomas Hobbes, is considered with a focus on then-contemporary theories of the structure and government of the first human societies. Critical perspectives on what have variously been proposed as sexist and feminist elements of Milton's Eden are surveyed. Milton's struggle with ...more
Structure of the Atom: A Conundrum. The work of E. Rutherford, 1911, lead to the discovery of the nucleus. In this lecture, Professor Sylvia Ceyer begins by explaining the backscattering experiment that lead to this key discovery in the early 20th century. She then moves on to a classical description of the atom, including coulombic interaction and the classical equation of motion (Newton's Second Law). The lecture ends with discussion ...more
The war saw a transformation of politics at both elite and popular level. This led to the Liberals being replaced by Labour as the main party of the Left. The last purely Liberal government came to an end in 1915. The inter-war leaders, Stanley Baldwin and Ramsay MacDonald, sought to continue the mission of liberalism by civilizing the state. Yet Britain's industrial structure remained geared to the past rather than the future, and ...more
In the undisputed Pauline epistles, marriage is seen as a way to extirpate sexual desire - neither as a means for procreation nor as the preferred social status. The Pastoral Epistles, written to instruct in the pastoring of churches and appointing of church offices, presents quite un-Pauline attitudes. In the Pastoral Epistles, the church, rather than an ecclesia, becomes a household, a specifically patriarchal structure in which men hold...more
