A Battle to Preserve Wardenclyffe, Tesla’s Bold Failure
It was the inventor’s biggest project, and his most audacious. The first tower rose on rural Long Island and, by 1903, stood more than 18 stories tall. One midsummer night, it emitted a dull rumble and proceeded to hurl bolts of electricity into the sky. The blinding flashes, The New York Sun reported, “seemed to shoot off into the darkness on some mysterious errand.” But the system failed for want of money, and at least partly for scientific viability. Today, a fight is looming over the ghostly remains of that site, called Wardenclyffe — what Tesla authorities call the only surviving workplace of the eccentric genius who dreamed countless big dreams while pioneering wireless communication and alternating current. A science group on Long Island wants to turn the 16-acre site into a Tesla museum and education center, and hopes to get the land donated to that end. “It’s hugely important to protect this site,” said Marc J. Recently, New York State echoed that judgment. Dr.
Physicists Achieve Quantum Teleportation of Photon Over 25 Kilometers
For the first time, a team of physicists have successfully teleported a quantum state of a photon to a crystal over 25 kilometers away through a fiber optic cable. This effectively showed that the photon’s quantum state, not its composition, is important to the teleportation process. The team was led by Nicolas Gisin of the University of Geneva and the results were published in the journal Nature Photonics. The quantum state of the photon is able to preserve information under extreme conditions, including the difference between traveling as light or becoming stored in the crystal like matter. To test this and ensure what they were observing was actually happening, one photon was stored in a crystal while the other was sent along optical fiber, over a distance of 25 kilometers. The photon did not physically “teleport” as we are used to hearing about in science fiction, where someone’s body can moved from place to place in a matter of seconds.

8 Ways Magnetic Levitation Could Shape the Future - How Maglev Technology Works
For years, NASA has been researching the possibility of using the high speeds of maglev transportation to fling spacecraft into low Earth orbit. "It would really open up space to human exploration and commercialization," Powell says. "It's something we can't do now because it's too expensive." Powell and his colleagues have proposed two generations of space launching technology. And that's just the first generation.

Hawking Radiation Recreated In A Laboratory
A researcher claims to have produced a simulation of Hawking radiation, which if true will give physicists the chance to test one of Stephen Hawking's most significant predictions. In 1974, Hawking upended ideas about black holes with his theory that just outside the event horizon, particle-antiparticle pairs should appear as a result of the black hole's gravitational field. One of these would be drawn into the hole, but the other escape. Hawking's equations have won widespread support from physicists, and are a major contributor to his reputation. Now Professor Jeff Steinhauer of the Technion-Israel Institute of Technology claims to be getting close. The fluctuations occur in pairs, modelling the particle-antiparticle pairs appearing around a black hole. In Nature, Steinhauer reported, “the observation of Hawking radiation emitted by this black-hole analogue.” Cowen notes that it is still unclear how well Steinhauer's creation models a real black hole.

Why Pot Makes You Feel Good

Last week, CNN’s Dr. Here’s what he — and those studying the chemistry of marijuana — now understand. Marijuana makes chemical contact with human bodies through cannabinoids, which are chemical compounds in marijuana (cannabis). Just as there was a time when we didn’t know we had immune systems or hormonal systems, until 1988 we didn’t know that we had cannabinoid systems. The human body produces and utilizes its own cannabinoids, but the body can also utilize cannabinoids from external sources. Any woman who has had a hot flash can find an analogy in the hormone estrogen. Other women, during menopause, seek to balance their hormonal systems through the use of a synthetic estrogen (rather than a plant-based one) such as with the pharmaceutical Premarin. So, in this analogy, pot is to a yam what Marinol is to Premarin.

Focus on the Red Dot and give us a like if the blue circle disappeared. This is a practical demonstration of the word 'focus'; when you focus on a thing, the remaining thoughts and objects should disappear.

When Parallel Worlds Collide . . . Quantum Mechanics Is Born
Parallel universes – worlds where the dinosaur-killing asteroid never hit, or where Australia was colonised by the Portuguese – are a staple of science fiction. But are they real? In a radical paper published this week in Physical Review X, we (Dr Michael Hall and I from Griffith University and Dr Dirk-André Deckert from the University of California) propose not only that parallel universes are real, but that they are not quite parallel – they can “collide”. In our theory, the interaction between nearby worlds is the source of all of the bizarre features of quantum mechanics that are revealed by experiment. Many worlds in existing interpretations The existence of parallel worlds in quantum mechanics is not a new idea in itself – they are a feature of one of the leading interpretations of quantum mechanics, the 1957 “many worlds interpretation” (MWI). First, its formalism is extremely remote from everyday experience. Heads or tails? Many interacting worlds Implications and applications
