...One of the earliest uses of nondestructive investigation was a joint US and Egyptian project to uncover chambers in the Second Pyramid at Giza belonging to Khafre. In 1965, a scientific proposal was submitted to a group of Egyptian physicists and archaeologists using cosmic-ray detectors (nuons technology). The American team, led by Dr. Luis Alvarez, suggested that, since there were two chambers in the superstructure of Khufu's Great Pyramid, and also two in the pyramid of his father, Sneferu, there should also be chambers located in the superstructure of Khafre's pyramid, who was Khufu's son...The Joint Pyramid Project was established...

Sailing through the smooth waters of vacuum, a photon of light moves at around 300 thousand kilometers (186 thousand miles) a second. This sets a firm limit on how quickly a whisper of information can travel anywhere in the Universe. While this law isn't likely to ever be broken, there are features of light which don't play by the same rules. Manipulating them won't hasten our ability to travel to the stars, but they could help us clear the way to a whole new class of laser technology. Physicists have been playing hard and fast with the speed limit of...
