Information is not destroyed but it is even more scrambled up than anyone thought by black holes. I have used the framework of relativization, to compute the temperature of the proposed firewalls. It would be about 1.410 septillion Kelvin. Relativization which has been developed in open peer reviewed literature and conference presentation in to a comprehensive theory combining General Relativity with Quantum Field Theory. Black holes shred information, then burn it in a furnace hotter than millions of Suns.
Higgs sector is the least advanced one in the Standard Model. There are two ways of developments – theoretical and semi-empirical. The main content of the latter is looking for physically meaningful regularities of the empirical parameter system especially in the ratios and hierarchies of masses and mixing angles in flavor groups.
Keeping the Gate is a "science and society" blog, which is to mean that it explores the relationship between science and society. Journalists and producers play critical roles in regulating that relationship. But the definition of journalism is changing as more and more people with compelling interests gain access to more and more channels through which to spin personal sentiments into the appearance of irrefutable fact.
September 14th 2015, 09:50 GMT. A far spread out distortion of space crossed earth's path. The distortion had traveled at the speed of light for more than a billion years, all along the way spreading out spherically and diluting its energy density inversely proportional to the spherical area covered. Still, when distorting the space occupied by earth, it did so with a peak power equal to the total electrical power consumption of human mankind.
Earth responded by undulating, expanding in one direction, shrinking in a perpendicular direction, and then reversing. And reversing. The frequency of undulation increased like a coin wobbling on a table top. And then suddenly, like a wobbling coin coming to rest, space became quiet again, and earth's shape stabilized.
Comment on the Number of Flavors in Standard Model
A widely used definition (see e.g. Wikipedia for a summery) of the number of particle ‘flavors’ in the SM is 6: 3 particle mass copies (e. g. electron, muon, tau for charged leptons; u, c, t for up-quarks …) doubled by the two up- and down- states.
Flavor is still a mystery in the SM. Historical Rabi’s quip “Who ordered the muon?” is steel urgent now for the three flavor mass copies of elementary particles.
I HAVE A VIRTUAL REALITY machine in my fridge. It’s a
banoffee pie, and when I eat two of them in the dark while listening to the
Beatles’ White Album, I am far, far away on another planet, no hardware
global tech industry doesn’t know about this (shhhh!), so this year, expect to see
virtual reality headsets on the shelf from Oculus Rift (Facebook), Samsung,
Sony, HTC and Google.
LIGO the Laser Interferometer Gravitational-Wave Observatory may announce the detection of gravitational waves tomorrow at 10:30AM Eastern time. I will watch it and live tweet it. The question of the day for most normal people will be... What are gravitational waves? See below for the answer to this question, and below that a live stream of my tweets on the subject as it happens.
UPDATE: The Perimeter Institute a hub of theoretical physics research will have their own livestream following the LIGO press conference.
UPDATE2: Updated to display a collection of my tweets on gravitational waves during and near the time of the press conference.
In an unprecedented decision, the U.S. Supreme Court has sort-of overruled a lower Circuit Court's decision to allow the "Clean Power Plan" to proceed pending final adjudication. The Supreme Court had never before granted a request to halt a regulation before review by a federal appeals court.

for a step-by-step derivation of the "Hamilton-Jacobi Schrödinger" equation) (Let me know about link issues to PDF)
Sir Willian Rowan Hamilton realized the equivalence of the Hamilton-Jacobi equation and the eikonal in 1834. With a little bit of imaginary work theoreticians of his time could have derived a quantum mechanical Hamilton-Jacobi equation equivalent to the Schrödinger equation.
“Beware of false knowledge; it is more dangerous than ignorance.” - George Bernard Shaw, Man and Superman, 1903.
It ain’t what you don’t know that gets you into trouble. It’s what you know for sure that just ain’t so. Mark Twain (1835-1910)
The so-called “Greenhouse effect” is one of the most persistent fallacies in popular science. It is a flawed speculation left over from the late 19th century, when it was first entertained by such scientific luminaries as Joseph Fourier, John Tyndall, and Svante Arrhenius.
In fact, however, the so-called “greenhouse gases” do not “trap” infrared energy radiated from the surface of the Earth, as proposed; they merely slow its inevitable return to outer space.
