Professor of Geology Walter Alvarez delivers the 2012 R. Lowry Dobson Memorial Lecture at Sibley Auditorium on the UC Berkeley Campus. Professor Alvarez demonstrates ChronoZoom (http://ChronoZoomProject.org), a timeline tool for visualizing all of history and presents a fascinating look at contingencies in Big History. The R. Lowry Dobson Memorial Lecture was created in 1999 to commemorate the life and passions of Dr. Lowry Dobson, a Berkeley alumnus, faculty member and research scientist. Established by friends and family to honor Dr. Dobson's deep belief in the interdisciplinary exploration of concepts and ideas, this lecture series brings together scientists of all disciplines to share new insights, ask new questions, and find new answers to the challenges that face our world. Lectures rotate annually among speakers chosen by the deans of biological, physical, and social sciences.

CS 61A - Spring 08 - The Structure and Interpretation of Computer Programs Instructor Brian Harvey Introduction to programming and computer science. This course exposes students to techniques of abstraction at several levels: (a) within a programming language, using higher-order functions, manifest types, data-directed programming, and message-passing; (b) between programming languages, using functional and rule-based languages as examples. It also relates these techniques to the practical problems of implementation of languages and algorithms on a von Neumann machine. There are several significant programming projects, programmed in a dialect of the LISP language. http://www.cs.berkeley.edu
