Physlets are physics applets that are free for non-commercial use and were created by the same team as the Open Source Physics Project. Since their creation at Davidson College in 1998, over 2,000 individual exercises have been created using Physlets for the teaching and learning of astronomy and physics on a variety of levels and a variety of ...
In particle physics, tracking is the process of reconstructing the trajectory (or track) of electrically charged particles in a particle detector known as a tracker.The particles entering such a tracker leave a precise record of their passage through the device, by interaction with suitably constructed components and materials.
A 60-foot dish mechanical tracking radar built by General Electric. Deployed at Shemya Island, Alaska, as a UHF radar and upgraded to L-Band in 1964. Used as tracker radar for Spacetrack network measurements once target detected. Principally used for intelligence purposes to track Russian missiles.
Opentracker is a free (licensed as beerware) BitTorrent peer tracker software (a special kind of HTTP or UDP server software) that is designed to be fast and to have a low consumption of system resources.
Tauberer started govtrack.us when he was a student at Princeton University.In 2005, GovTrack was the first to make U.S. federal legislative information comprehensively available in an open, structured data format for researchers, journalists, other public interest projects, and anyone to freely reuse for any purpose.
Project Space Track was a research and development project of the US Air Force, to create a tracking system for all artificial satellites of the Earth and space probes, domestic and foreign. Project Space Track was started in 1957 at the Air Force Research Laboratory at Laurence G. Hanscom Field, now Hanscom Air Force Base , in Bedford ...
An avid track fan from a young age, he and Roberto Quercetani compiled from 1948 the renowned annual world rankings in Track and Field News. [16] He was a co-founder of ATFS and of the Federation of American Statisticians of Track (with Scott Davis and Stan Eales). [15] He died November 1, 2001, in Santa Barbara, California. [15]
The Henyey track is a path taken by pre-main-sequence stars with masses greater than 0.5 solar masses in the Hertzsprung–Russell diagram after the end of the Hayashi track. The astronomer Louis G. Henyey and his colleagues in the 1950s showed that the pre-main-sequence star can remain in radiative equilibrium throughout some period of its ...
