Why ethane has a rotational barrier is still debatable. Analyzing conformational and configurational stereotopicity relationships among constitutionally equivalent groups reveals a subtle discrimination in enzyme reactions. When Baeyer suggested strain-induced reactivity due to distorting bond angles away from those in an ideal tetrahedron, he assumed that the cyclohexane ring is flat. He was soon corrected by clever Sachse, but Sachse's w...more

Our understanding of the economy will be more tangible and vivid if we can in principle explain all the economic decisions of every agent in the economy. This lecture demonstrates, with two examples, how the theory lets us calculate equilibrium prices and allocations in a simple economy, either by hand or using a computer. In future lectures we shall extend this method so as to compute equilibrium in financial economies with stocks and bon...more

In this lecture on the work of Roman Jakobson, Professor Paul Fry continues his discussion of synchrony and diachrony. The relationships among formalism, semiotics, and linguistics are explored. Claude Levi-Strauss's structural interpretation of the Oedipus myth is discussed in some detail. In order to differentiate Jakobson's poetic functions, Professor Fry analyzes the sentence "It is raining" from six perspectives. Significant attention...more

In this lecture on the postmodern psyche, Professor Paul Fry explores the work of Gilles Deleuze, Felix Guattari and Slavoj Žižek. The notion of the "postmodern" is defined through the use of examples in the visual arts and architecture. Deleuze and Guattari's theory of "rhizomatic" thinking and their intellectual debts are elucidated. Žižek's film criticism, focused on the relation between desire and need, is explored in connection with Lacan.

Kawasaki talks about marketing and product design simplified. Kawasaki explains why this theory is all an entrepreneur will need to know about marketing. A simple chart illustrates his point - how to be the creator of a unique product or service and is valuable to a customer.

The lecture begins with further exploration of the question of whether it is desirable to live forever under the right circumstances, and then turns to consideration of some alternative theories of the nature of well-being. What makes a life worth living? One popular theory is hedonism, but the thought experiment of being on an "experience machine" suggests that this view may be inadequate.

In this lecture, Professor Paul Fry explores the semiotics movement through the work of its founding theorist, Ferdinand de Saussure. The relationship of semiotics to hermeneutics, New Criticism, and Russian formalism is considered. Key semiotic binaries--such as langue and parole, signifier and signified, and synchrony and diachrony--are explored. Considerable time is spent applying semiotics theory to the example of a "red light" in a va...more

Professor Sylvia Ceyer covers crystal field theory in both the tetrahedral case and the square planar case. The discussion then moves to the spectrochemical series and strong/weak field ligands. A conversation on magnetism, both paramagnetic and diamagnetic, in transition metals concludes the lecture.
-
Youthful chemists Couper and Kekulé replaced radical and type theories with a new approach involving atomic valence and molecular structure, and based on the tetravalence and self-linking of carbon. Valence structures offered the first explanation for isomerism, and led to the invention of nomenclature, notation, and molecular models closely related to those in use today.

Psychoanalytic theory illuminates the polarised nature of the asylum debate and the powerful feelings for and against refugees. Historic, literary and clinical examples reveal migration as part of human nature and the unconscious forces revolving around the concept of exile.
-
We discuss evolution and game theory, and introduce the concept of evolutionary stability. We ask what kinds of strategies are evolutionarily stable, and how this idea from biology relates to concepts from economics like domination and Nash equilibrium.

Professor McBride introduces the theory behind light diffraction by charged particles and its application to the study of the electron distribution in molecules by x-ray diffraction. The roles of molecular pattern and crystal lattice repetition are illustrated by shining laser light through diffraction masks to generate patterns reminiscent of those encountered in X-ray studies of ordered solids.
