links which
give a complete overview of horology, the study of time and
timekeeping.

discussion focuses on restoration and the general business of clocks.
Still, the
list is interactive, as all lists, providing opportunity to express
opinions and
ask questions.
-History of Clocks
A Walk
Through Time:
A brief stroll through the history of timekeeping. This page was
designed by the
National Institute of Standards and Technology (NIST) to trace the
evolution of
timekeeping from ancient devices to their own, contemporary
calibrations.
Greeks: Thales
to Ptolemy: History of timekeeping and its devices in ancient
Greece.
-Evolution of the Scientific Understanding of Time
Stephen Hawking's Universe: A good site for exploring the physical nature of the universe. Hawking says that he will address questions such as: "Where do we come from? How did the universe begin? Why is the universe the way it is? How will it end?" This site was suggested by a classmate, Winter 2000.
Museo
della
Specola: English version of the home page for Museo della Specola.
This page
includes internal links to text on the history of atronomical discover,
with
particular focus on that history in Bologne, Italy. Very useful in
tracing the
intellectual history of scientific discovery relating to time and time
measurement.
Newton Museum: suggested by a student in the class Winter 2000, this is
"the virtual museum of Sir Isaac Newton and the history of science." Of special note is the section on Anecdotes and Essays about Newton.
Time Magazine's "Person of the Century": Albert Einstein.
The December 31, 1999 issue.
Einstein Exhibit:
Maintained
by the American Institute of Physics, this site contains some
interesting material
on Einstein, from original papers to a recording of him explaining his
famous
formula stating the equivalence of mass and energy.

given links
to a more extended, cross-referenced definition. Good for comparison
and
clarification.

dimension, time travel, and the nature of the universe. Like all material you find on the web, you should be sure to check this one for
accuracy.
A Geometry Forum on the Fourth Dimension: This website houses a
Newsgroup's
discussion on the fourth dimension.

Scientists Slow Light To a Crawl By TOM KIRCHOFER
Associated
Press Writer, February 19, 1999: This is the article, for which we do not have a link yet,
that speaks of
the experiments with the speed of light conducted at the Rowland
Institute for
Science in Cambridge and Harvard University. In commenting on this article, Professor Mook has said: "As I understand this, it is just a super, super refractive index. Light is being slowed down by passage through a medium--no big deal. What is big news here is that the speed is incredibly slow. But there is nothing to undo Einstein's second postualte or Maxwell's equations. Actually the second postulate is just a special case of the first postulate: the laws of physics are the same in all inertial reference frames. Since Maxwell's equations predict a speed for light that is independent of the motion of the source or reciever of the light, Einstein's second postulate follows immediately. And there has never, ever been any evidence that Maxwell's equations are in error. They are the only part of "classical" physics that has survived relativity theory unscathed."
