With a little help from the units program, we can answer this:<BR/><BR/>If the 350MJ figure is right, this is about 2 x 10^15 TeV which suggests something on the order of 10^15 nucleons in the beam, since the energy to be achived is a few TeV per nucleon. This many nucleons has a rest mass of order 10^-12 kg (a few nanograms). <BR/><BR/>On the other hand SLhttps://www.blogger.com/profile/13692296986623431305noreply@blogger.comtag:blogger.com,1999:blog-22973357.post-89250401673218001172008-01-11T23:40:00.000-05:002008-01-11T23:40:00.000-05:00Hi again,do you happen to know when LHC will actua...Hi again,<BR/><BR/>do you happen to know when LHC will actually be operative? the nov.07 deadline did not hold!<BR/><BR/>How much matter (protons) is actually traveling in that beam?<BR/><BR/>I hear, that the energy of the beam could be compared to a train of 400t traveling at 150km/t.<BR/>That would be approximately 350Mj<BR/><BR/>gest<BR/><BR/>KlausAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-22973357.post-23421691709198238162008-01-11T22:29:00.000-05:002008-01-11T22:29:00.000-05:00If only the U.S. high-energy physics community cou...If only the U.S. high-energy physics community could market itself as well as the LHC folks do here, Fermilab might not be in the dire situation in which it's in today.Sebastian Thalerhttps://www.blogger.com/profile/00371442504447981232noreply@blogger.comtag:blogger.com,1999:blog-22973357.post-14887176272991318842008-01-11T20:23:00.000-05:002008-01-11T20:23:00.000-05:00Hi Bee,Good flick.

I must tell you however when I first saw Dr. Brian Cox’s face on the YouTube still shot, he sort of reminded me of Ted Login (Keanu Reeves) from the Bill and Ted movies. I was expecting to hear him start up by saying something like “hey dudes we are about to begin another excellent adventure with this Large Hadron Collider gismo”. Then of course Dr. Cox comes on Phil Warnellhttps://www.blogger.com/profile/15671311338712852659noreply@blogger.comtag:blogger.com,1999:blog-22973357.post-20597356351532968782008-01-11T16:19:00.000-05:002008-01-11T16:19:00.000-05:00Greetings!here another good video on the LHC:http:...Greetings!<BR/><BR/>here another good video on the LHC:<BR/><BR/>http://youtube.com/watch?v=fPxYdObyJ2A&feature=related<BR/><BR/>Best<BR/>KlausAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-22973357.post-15055224567423128222008-01-11T12:45:00.000-05:002008-01-11T12:45:00.000-05:00yeah, the movies make quite a professional impress...yeah, the movies make quite a professional impression. neat little introductions, and in addition easily bloggable ;-)Sabine Hossenfelderhttps://www.blogger.com/profile/06151209308084588985noreply@blogger.comtag:blogger.com,1999:blog-22973357.post-88251453857785515592008-01-11T12:43:00.000-05:002008-01-11T12:43:00.000-05:00Cool movies!
