Fermilab Corrects Speed of LightAnita Schlift, Science Correspondent_____________________________Scientists at Fermilab in Illinois claim they've measured C - thetpeed of light in a vacuum - with unparalleled accuracy using whatthey are calling the "photon-interlace relay technique," or PIRT.Before PIRT, the most accurate method used laters anad cesiumclocks. That method yielded a speed of 299,792,458 meters persecond - a figure considered so accurate that the internationaldefinition of the meter was changed to "the length of the pathtraveled by light in vacuum during a time interval of 1/299 792 458of a second."Now, however, PIRT can time a single photon, not the first photonof a beam. Dr. Anton Chaudhary of Fermilab insists that PIRTproduces a more reliable measure of speed and that C - whichhas not been measured since the 1983 re-definition of the meter -may actually be faster than believed."PIRT indicates that the speed of the light in a vacuum is at least 299,792,665 meters per second," he says," And the math adds up. It's ashame to reprint all those textbooks and encyclopedias, but it alladds up. You can't argue with math. That's what so many peoplehate about it."The PIRT system relies on Fermilab's particle accelerator, which[SEE "LIGHT, PAGE 5D]
We will wait for Leon the Men Of ForMat to approve the format.
What is the roll for spotting a stone?, and the diff too.And what the successes to get (One stone, Two stones, Three stones and so on)?Thanks.
