Schrödinger’s Cat: Explained. Erwin Schrödinger was born in Vienna on August 12, 1887 and was awarded the Nobel Prize in Physics in 1933.
He is best known for his work regarding quantum theory, particularly about his thought experiment involving a cat in order to explain the flawed interpretation of quantum superposition. The Copenhagen Interpretation of quantum mechanics essentially states that an object in a physical system can simultaneously exist in all possible configurations, but observing the system forces the system to collapse and forces the object into just one of those possible states. Schrödinger disagreed with this interpretation. So what does this have to do with cats? Schrödinger wanted people to imagine that a cat, poison, a geiger counter, radioactive material, and a hammer were inside of a sealed container.
Of course, Schrödinger claimed, that was ridiculous. This video from Sixty Symbols does an excellent job at explaining the Shrödinger’s Cat Paradox: Could cold spot in the sky be a bruise from a collision with a parallel universe? Scientists have long tried to explain the origin of a mysterious, large and anomalously cold region of the sky.
In 2015, they came close to figuring it out as a study showed it to be a “supervoid” in which the density of galaxies is much lower than it is in the rest of the universe. However, other studies haven’t managed to replicate the result. 'We Don't Planet' Episode 3: What's Up with Gravitational Lensing? The fundamental description of gravity under general relativity — that the presence of matter and energy deforms the fabric of space-time, and this deformation influences the motion of other objects — leads to a rather unexpected result: a massive object can act like a lens, magnifying and warping the images of background objects.
This prediction was the first major test of general relativity, with Sir Arthur Eddington leading an expedition to measure the small (but detectable) deflection of starlight around our sun, and today this facet of our universe is used as a powerful cosmological probe.

Answer: Triboluminescence The word might sound rather scientific, and maybe a little alien in nature (“triboluminescence” does sound a whole lot like a problem the crew of the Enterprise might run into, after all), but it’s a down-to-Earth phenomenon you may have even experienced yourself.
Triboluminescence is light created when crushing, tearing, or other mechanical action triggers the breakdown of chemical bonds in a material (or when peeling adhesive tapes). A popular classroom demonstration of this phenomenon, for example, is to give students rolls of Wint-O-Green Mint Lifesaver candies, enter a darkened room, and then have the students—much to their delight—throw tons of the candies into their mouths and chomp on them vigorously with their mouths open.

EINSTEIN AND QUANTUM MECHANICS. No, Scientists Didn't Just Create Negative Mass or Defy the Laws of Physics. Finding faster-than-light particles by weighing them. In a new paper accepted by the journal Astroparticle Physics, Robert Ehrlich, a recently retired physicist from George Mason University, claims that the neutrino is very likely a tachyon or faster-than-light particle.
There have been many such claims, the last being in 2011 when the "OPERA" experiment measured the speed of neutrinos and claimed they travelled a tiny amount faster than light. However, when their speed was measured again the original result was found to be in error – the result of a loose cable no less. Ehrlich's new claim of faster-than-light neutrinos is based on a much more sensitive method than measuring their speed, namely by finding their mass. The result relies on tachyons having an imaginary mass, or a negative mass squared.
Imaginary mass particles have the weird property that they speed up as they lose energy – the value of their imaginary mass being defined by the rate at which this occurs. Skeptics of tachyons often cite conflicts with relativity theory. The LHC Just Discovered A New System of Five Particles. A Unique Find The Large Hadron Collider (LHC), the latest addition to CERN’s accelerator complex, is the most powerful particle accelerator ever built.
It features a 27 kilometer (16 mile) ring made of superconducting magnets and accelerating structures built to boost the energy of particles in the chamber. In the accelerator, two high-energy particle beams are forced to collide from opposite directions at speeds close to the speed of light. The energy densities that are created when these collisions occur cause ordinary matter to melt into its constituent parts—quarks and gluons.

In 1905, a team of construction workers in the small village of Shoreham, New York labored to erect a truly extraordinary structure. Over a period of several years the men had managed to assemble the framework and wiring for the 187-foot-tall Wardenclyffe Tower, in spite of severe budget shortfalls and a few engineering snags. The project was overseen by its designer, the eccentric-yet-ingenious inventor Nikola Tesla (10 July 1856 – 7 January 1943). Atop his tower was perched a fifty-five ton dome of conductive metals, and beneath it stretched an iron root system that penetrated more than 300 feet into the Earth’s crust.

Physicists Have Modeled the Existence of Newly Discovered Tetraneutrons. In Brief A new study has confirmed previous research on the existence of tetraneurons — a particle with more than two neutrons. The research challenges the current model of particle physics and means we may have to reexamine how we look at nuclear forces like neutron stars. Simulating The Impossible Back in February, physicists from Japan presented evidence that they may have generated tetraneutrons, a particle consisting of four neutrons. But we had no model that revealed how they could possibly exist. Until now. Now, an international team of scientists have used sophisticated supercomputer simulations to show how a tetraneutron could be quasi stable, revealing data that matched with the previous Japanese experiment, according to a new study published in Physical Review Letters.
High-intensity fusion. Pablo Rodriguez Fernandez is hunched over a computer in the control room of MIT’s fusion reactor, gathering data that will inform the design of a new one — a device that could solve the world’s energy problems. He is surrounded by other scientists running simulations and analyzing data. Their work is spread across tables and desks covered in computers and a chaos of wires. The objective: to design a machine that will harness the same energy process that powers the sun and deliver it to the world, carbon free. They are here to make fusion energy a reality.
This is the headquarters of a MIT’s Alcator C-Mod. On this day in mid-September, as Fernandez and his fellow graduate students in the Department of Nuclear Science and Engineering type, calculate, and predict, the machine is operating on the other side of a nearby concrete wall. Despite its apparently casual atmosphere, C-Mod has also established stringent safety standards that have been widely exported across the MIT campus. WMAP- Cosmological Constant or Dark Energy.

A Quantum Teleportation Breakthrough: Physicists Just Smashed Previous Records. In Brief Two separate teams of scientists have successfully conducted the world's first quantum teleportation outside of a laboratory. While the setup of both tests have variations, the conclusion is essentially the same: quantum teleportation is possible.

From: firstname.lastname@example.org To: WEINBERG@utaphy.ph.utexas.edu Subject: NYRB Date: Sun, Sep 22 1996, 17:14:44 Dear Professor Weinberg, In your recent response in the NYRB, you ask George Levine, my colleague here at Rutgers, to "suppose that physicists were to announce the discovery that, beneath the apparently quantum mechanical appearance of atoms, there lies a more fundamental substructure of fields and particles that behave according to the rules of plain old classical mechanics.

EUROfusion. ITER - the way to new energy. Fusion: Fusion - a clean future. Little reactors may be best path to nuclear fusion - tech - 05 November 2014. IT ALWAYS seems to be 30 years away. Controlled nuclear fusion seems no closer to being realised now than it was when the idea was put forward in the 1950s. But fusion power stations might be closer than anyone suspected – if we think small. Bigger is better, or so goes the accepted wisdom with nuclear fusion. The massive international experiment ITER takes this to the extreme, employing a doughnut-shaped reaction chamber 20 metres across and up to 1000 staff. The price tag? Now some are advocating that a smaller-scale approach could be swifter and cheaper. Fusion reactors promise cheap, clean energy, leaving behind only small amounts of radioactive waste and with little risk of runaway meltdowns.
