Winter 2008 General information
Physics 427A
INSTRUCTOR: Prof. David Thouless. I can usually be reached by e-mail
at thouless@u.washington.edu, but my access to e-mail may be difficult
between December 6, 2007, and January 10, 2008. My office is in the
Physics and Astronomy Building, B423 (fourth floor of the building to the
right of the Physics Tower).
SUBJECT MATTER: My title for the course is Modern Physics and the
Modern World. This course is intended to explore developments in
physics since 1930, after the revolution that began with the discovery of
X-rays and radioactivity, and culminated in quantum mechanics was
completed and widely understood by young scientists. It is intended as a
400 level course with modest prerequisites, such as some familiarity with
modern atomic and quantum physics, electromagnetism, and thermal physics,
at the introductory level. The course should cover topics where new
physics has led to new advances in technology or in other branches of
science or knowledge. It is not intended to include advances that are
primarily applications of earlier physics, such as the development of
X-ray tomography, electron microscopy, or the structure of DNA, even
though they were brought about by those trained as physicists, in many
cases working in physics laboratories; Francis Crick, one of the
discoverers of the double helix, was such a person.
METHODS OF INSTRUCTION: The course will involve a combination of brief
lectures on the basic science underlying technological advances such as
integrated semiconductor circuits, lasers, nuclear resonance,
superconducting magnets, and magnetic memories, together with student led
discussions of how the fundamental physics relates to the actual
applications. I hope also to cover some advances that have led to
important porgress in other areas of knowledge, such as cosmology,
astrophysics, and precision measurement. In honor of the 2007 Nobel Prize
award I think we should start by discussing advances in magnetism fairly
early in the course, so do some reading and web-browsing on this in the
first week of next quarter.
CLASS TIMES: times to be arranged. I will arrange a class meeting on
Friday, January 11 to finalize class arrangements. Please send me a
message with your constraints and preferences if you are taking this
class. I should be available at any time from 9 am onwards on that day.
PREREQUISITES: I expect students to be happy with the basic ideas of
quantum theory, statistical mechanics, at the level of an introductory
college physics course.
METHODS OF INSTRCTION: On average I hope to use about one third of the
class time for lectures on the basic physics, one third for presentations,
by the students, by me, or by an outside expert, on the applications of
the "new" physics, and one third for discussion. I aim to give guidance
on finding the relevant literature, but I hope that the students will
search for relevant and intelligible papers, and will share their
discoveries with the rest of us.
