Profile

Harry Lewis is Gordon McKay Professor of Computer Science in the School of Engineering and Applied Sciences at Harvard University. He is the author of six books and numerous articles on various aspects of computer science. Over his more than thirty years of teaching he has helped launch thousands of Harvard undergraduates into careers in computer science.

His book about higher education, Excellence Without a Soul: Does Liberal Education Have a Future was a Boston Globe best-seller and the subject of favorable reviews in both the Boston Globe and the Wall Street Journal. It has been translated into Chinese (in both Taiwanese and mainland editions) and Korean. He is coauthor with Hal Abelson and Ken Ledeen of Blown to Bits: Your Life, Liberty, and Happiness After the Digital Explosion (2008), which explains for the general reader the origins and public consequences of the explosion of digital information.

From 1995-2003 Lewis served as Dean of Harvard College. In this capacity he oversaw the undergraduate experience, including residential life, career services, public service, academic and personal advising, athletic policy, and intercultural and race relations. He is a long time member of the College’s Admissions Committee.

Lewis has worked extensively on the algorithmic solvability of logical, computational, and combinatorial systems, attempting to clarify the relations between them and to identify their common characteristics. He is also actively involved in the use of computers in education, and his books have had a significant influence on the teaching of the foundations of computer science to undergraduates.
The Hong Kong Lectures were delivered in January, 2011. Here are the ppts:
Civic Edcuation -- Approaches to General Education -- Future of Ignorance --Idea Economy
I blog sporadically about education, the digital explosion, and other topics of interest at my Bits and Pieces blog. This blog expands the subjects I had previously blogged at Blown to Bits, the site associated with the book of that name by Hal Abelson, Ken Ledeen, and myself.

In the fall term 2011, I teach Computer Science 121, Introduction to Formal Systems and Computation. This course was also offered as a distance learning course through the Harvard Extension School as CSCI E-207. I am also teaching a Freshman Seminar on Amateur Athletics.
In the spring term, 2012, I will be teaching a new course on Discrete Mathematics for Computer Science, Computer Science 20. The Extension School will be offering a distance version of this course.

This course focuses on information as quantity, resource, and property. We study the application of quantitative methods to understanding how information technologies inform issues of public policy, regulation, and law. How are music, images, and telephone conversations represented digitally, and how are they moved reliably from place to place through wires, glass fibers, and the air? Who owns information, who owns software, what forms of regulation and law restrict the communication and use of information, and does it matter? How can personal privacy be protected at the same time that society benefits from communicated or shared information?



Free lecture videos

The recorded lectures are from the Harvard Faculty of Arts and Sciences course Quantitative Reasoning 48, which was offered as an online course at the Extension School.
The Quicktime and MP3 formats are available for download, or you can play the Flash version directly. These lectures are organized by 12 themes, which can be viewed in any order. Note that some topics are repeated in different themes, as relevant.

Blog posts

Harry Lewis provides commentary and analysis on his blog, Blown to Bits. Blog posts are linked below with the videos.
