Globe at Night results are in 2008 are in! The international star-hunting activity known as GLOBE at Night inspired 6,838 measurements of night-sky brightness by citizen scientists around the world, including 660 digital measurements using handheld sky-quality meters. The 2008 campaign received measurements from 62 countries, surpassing last year’s total of 60 countries.

It is with some sadness that I just learned that John A. Wheeler died Sunday April 13 at the age of 96. I also just learned about a multi-session interview available online at http://www.aip.org/history/ohilist/5908_1.html. The interview was conducted by Kenneth Ford, one of Wheeler's students, as research for the latter's autobiography, Geons, Black Holes, and Quantum Foam: A Life in Physics (Norton, 1998).

This interview is one of the first 50 of about 500 oral history interviews with physicists, astronomers and geophysicists from the AIP Niels Bohr Library & Archives collection that are online with the support of an NEH grant. For a list of all oral histories in the collection, see http://aip.org/history/ohilist/. In addition, there is a list of those that are currently online at http://aip.org/history/ohilist/transcripts.html.

Thanks, Joe Anderson, Niels Bohr Library & Archives for the heads-up!

A collection of more than 30,000 historical photographs, slides, lithographs, engravings, and other visual materials, the Emilio Segrè Visual Archives focuses on American physicists and astronomers of the twentieth century, but includes many scientists in Europe and elsewhere, in other fields related to physics, and in earlier times.

The collection is named in honor of Emilio Segrè, best known for his Nobel Prize-winning work in nuclear and high-energy physics, but also an avid photographer and author of books on the history of modern physics.

Check the site out for images of scientists at work, family groups and offical portraits. Fascinating!
