Let’s welcome David Berenstein, physics Professor at the University of California, Santa Barbara, to the blogosphere. David is a particle physics/stringy sort of theorist, and I encourage you to drop by and check out his new blog, Shores of the Dirac Sea.

Cosmic Variance is a group blog by people who, coincidentally or not, all happen to be physicists and astrophysicists:
Our day (and night) jobs notwithstanding, the blog is about whatever we find interesting — science, to be sure, but also arts, politics, culture, technology, academia, and miscellaneous trivia. We have similar outlooks on many things, widely disparate opinions about others, and will do our best to keep the discourse reasonably elevated.

If the protons in the LHC travel at almost the speed of light why does the LHC Beam take so long to traverse the circumference of the LHC? Please Explain
Thank You

Mark,
Thanks for the shout. Now I’m swamped! How do you handle it all?

Welcome, David! Mostly we ignore it.
Gerald, the only reason it took so long for the beam to go around the LHC is because they kept stopping it to check that all was well. Under ordinary operations, it will take a microblink for a bunch of protons to zip around.
