    There’s one interpretation of the meaning of quantum mechanics that manages to skip a lot of the unphysical weirdness of the mainstream interpretations: it's de Broglie-Bohm pilot wave theory. There are some pretty out-there explanations for the processes at work behind the incredibly successful mathematics of quantum mechanics - things are both waves and particles at the same time, the act of observation defines reality, cats are alive and dead, or even: the universe is constantly splitting into infinite alternate realities. The weird results of quantum experiments seem to demand weird explanations of the nature of reality. In this episode,...

    Bizarre quantum bonds connect distinct moments in time, suggesting that quantum links - not space-time - constitute the fundamental structure of the universe. ... A field is a highly entangled system. Different parts of it are mutually correlated: A random fluctuation of the field in one place will be matched by a random fluctuation in another. ("Parts" here refers both to regions of space and to spans of time.) Even a perfect vacuum, which is defined as the absence of particles, will still have quantum fields. And these fields are always vibrating. Space looks empty because the vibrations cancel each...

    Researchers have written quantum code on a silicon chip for the first time And so it begins... FIONA MACDONALD 17 NOV 2015           For the first time, Australian engineers have demonstrated that they can write and manipulate the quantum version of computer code on a silicon microchip. This was done by entangling two quantum bits with the highest accuracy ever recorded, and it means that we can now start to program for the super-powerful quantum computers of the future.Engineers code regular computers using traditional bits, which can be in one of two states: 1 or 0. Together, two bits...
  • How Richard Feynman went from stirring jelly to a Nobel Prize

    Nobel Prize-winning and eccentric physicist Richard Feynman has been called a buffoon and a magician, but is lauded as a man who could make science accessible and interesting for all. When I was a child I desperately wanted to be a scientist, but then it all went wrong. Unfortunately, during the early years of my secondary school education, science became joyless. It was a subject that seemed disjointed from the world even though it is the method that attempts to explain the world and the universe. If only it were possible to place an automaton Richard Feynman in every school....
  • Media Reports Connect Saddam to 9/11 Plot

    The 9/11 Commission tells us in detail that the terrorist attacks on America on 9/11 were set in motion in December 1998. They report that interrogations of the plot's mastermind, Khalid Sheik Mohammed, demonstrate that the plot was set in motion in "late 98 early 99" at a meeting in Khandahar, Afghanistan. This also happens to be the time period that Iraq came under bombardment by the United States. The timing is no accident. They reported that the only time Osama bin Laden was in Khandahar during the time period of "late 98 early 99" was between December 18 and...
  • Four arrests linked to Chinese spy ring

    Four persons arrested in Los Angeles are part of a Chinese intelligence-gathering ring, federal investigators said, and the suspects caused serious compromises for 15 years to major U.S. weapons systems, including submarines and warships. U.S. intelligence and security officials said the case remains under investigation but that it could prove to be among the most damaging spy cases since the 1985 one of John A. Walker Jr., who passed Navy communication codes to Moscow for 22 years. The Los Angeles spy ring has operated since 1990 and has funneled technology and military secrets to China in the form of documents...
