The reading for our next meeting, Tue. Jan. 31, is available under
SU's blackboard site: blackboard.syr.edu . You will need your NetID
to login and see or print the article. Go to the "Readings" link.
If you have trouble accessing the article, please let me know.

The article "Gravitational Wave Observatories" from Scientific American,
June 1987, is less technical than our previous reading, but still assumes
some scientific background. So look up terms and ask questions.

A number of background sites are available on line; one featuring a video
by Gabriela Gonzalez, a former Syracuse graduate student working with
Peter Saulson, is available at

Here are some questions to think about:

What types of waves are there that can travel across interstellar or
intergalactic space?

What is the status of LIGO now?
Where was LIGO supposed to be built? Where was it built?

[A more quantitative question:
How big is 0.000000000000000000000001 meters compared to a proton?]

I look forward to our discussion on Tuesday,
Alan Middleton
