Praise for The Elements The printing quality of this book is truly extraordinary. The pictures leap out from a deep black background, just as brightly as they do on the computer screen. (And the metalized cover is pretty nifty!) If you don't believe me how packed this book is with elements, take a look at this complete catalog of the pages in the book. The Elements by Theodore Gray

Home Contents Next Among the physical laws it is a general characteristic that there is reversibility in time; that is, should the whole universe trace back the various positions that bodies in it have passed through in a given interval of time, but in the reverse order to that in which these positions actually occurred, then the universe, in this imaginary case, would still obey the same laws. To test reversibility, we may imagine what we may call "the reverse universe," that is to say, another, an imaginary universe, in which the positions of all bodies at various moments of time are the same as in our real universe, in which those positions occur at the same respective intervals of time but in the reverse order.

HOUSTON — A warp drive to achieve faster-than-light travel — a concept popularized in television's Star Trek — may not be as unrealistic as once thought, scientists say. A warp drive would manipulate space-time itself to move a starship, taking advantage of a loophole in the laws of physics that prevent anything from moving faster than light. A concept for a real-life warp drive was suggested in 1994 by Mexican physicist Miguel Alcubierre; however, subsequent calculations found that such a device would require prohibitive amounts of energy. Now physicists say that adjustments can be made to the proposed warp drive that would enable it to run on significantly less energy, potentially bringing the idea back from the realm of science fiction into science.
Egyptian Teenager Creates Next-Generation Quantum Space Propulsion System An Egyptain teenager has patented a next-generation propulsion system that could send spacecraft to other solar systems—without using a single drop of fuel. While it is not quite warp-drive technology, young physicist Aisha Mustafa’s system is based on quantum physics and could see mankind boldly go where no man has gone before. The 19-year-old is further proof that young minds produce fresh new ideas. Her propulsion system gets rid of traditional rocket boosters in favor of a more futuristic concept. For those of you who aren’t up to scratch on quantum physics, Mustafa’s idea works on the principle that space is not a vacuum.
Researchers send instant message with neutrinos A group of scientists led by researchers from the University of Rochester and North Carolina State University have for the first time sent a message using a beam of neutrinos – nearly massless particles that travel at almost the speed of light. The message was sent through 240 meters of stone and said simply, “Neutrino.” “Using neutrinos, it would be possible to communicate between any two points on Earth without using satellites or cables,” said Dan Stancil, professor of electrical and computer engineering at NC State and lead author of a paper describing the research. “Neutrino communication systems would be much more complicated than today’s systems, but may have important strategic uses.” Many have theorized about the possible uses of neutrinos in communication because of one particularly valuable property: they can penetrate almost anything they encounter.
