Here are some Selected Papers.

Here is a link to my Atlas of Surfaces of Section for the Restricted Problem of Three Bodies, now available on the web after being out of print for several years.

To learn more about Harlan Smith, click here. To see the brochure that U.T. issued to inaugurate the Smith Professorship, click here. The brochure was put out nearly a decade ago, so it is dated (my beard is grayer, and my kids are grown up...see above). It describes what we planned to do with the Hubble at that time (before the Challenger accident and before major changes in the HST program). It also includes some personal information about Harlan Smith.

I was the Principal Investigator for the Hubble Space Telescope Astrometry Science Team. We were involved with developing the HST Fine Guidance Sensors as astronomical instruments, and we are now using them in scientific investigations.

A number of folks have asked about our farm in Fayston,Vermont, to which Sue and I have retired. I have put up some pictures for your enjoyment. More will go up in due course, showing the result of our remodelling project. (But I have to take them first!)

Here is a link to the 1995 New York Howlerfest Home Page. The Howlerfest took place on July 28, 1995 at the Museum of Natural History in New York. See the professors of the University of Ediacara! See the action at the Panda's Thumb!
