David Saltzberg

David Saltzberg, Ph.D. (b. 1967) is an astroparticle physicist and the science consultant for the CBS television situation-comedy, The Big Bang Theory, checking scripts and meeting with the producers, writers, actors, set decorators, prop masters, and other crew to help ensure scientific accuracy of the show. He has been the show's science consultant ever since the unaired pilot. He also writes a blog, The Big Blog Theory, that explains the science behind the episodes.
==Career==
David Saltzberg is a professor of Physics and Astronomy at the University of California, Los Angeles (UCLA). He received a bachelor's degree in physics in 1989 from Princeton University where he worked in the Princeton Cyclotron. He received his Ph.D. in physics from the University of Chicago in 1994, where he measured the mass of the W boson at the Fermilab Tevatron and CDF detector.
In 1995–97, he performed post-graduate work at CERN on the CHORUS experiment looking for oscillations with a 1-ton photographic emulsion target.
Saltzberg returned to the U.S. and CDF as a faculty member at UCLA where he and his group helped build the CDF Run-II detector at the Fermilab Tevatron. His group looks for signs of supersymmetry and measures exotic properties of the top quark.
Saltzberg's current interests are high energy particle physics and high-energy neutrino astronomy, using radio detection techniques. He is currently working on the ANITA project, which recently completed three successful scientific balloon flights in Antarctica, and also collaborating with the CMS experiment at the Large Hadron Collider at CERN.
==Appearances==
===The Big Bang Theory===
David Saltzberg appears in the following specials from The Big Bang Theory:
* Physicist to the Stars (2009)
* Access All Areas (2012)
* He appeared once sitting in the background of a cafeteria scene (TBBT S3E10). 
* He also makes an appearance when Sheldon first arrives at Caltech for graduate studies in 1994 (YS S7E14).
* He posted good comments about Leonard and Sheldon's bubble theory.
* He posted good comments about Sheldon and Amy's Super-Asymmetry paper.
===Young Sheldon===
In the last episode of Young Sheldon, teenager Sheldon goes to the Caltech university, where David portrays a professor, asks if he is lost. Sheldon denies this and says he is exactly where he should be. He walks off as the camera pans to a panorama of the university campus.
