Deconstructing Schrödinger's cat
The paradox of Schrödinger’s cat—the feline that is, famously, both alive and dead until its box is opened—is the most widely known example of a recurrent problem in quantum mechanics: its dynamics seem to predict that macroscopic objects (like cats) can, sometimes, exist simultaneously in more than one completely distinct state. Many physicists have tried to solve this paradox over the years, but no approach has been universally accepted. Now, however, theoretical physicist Franck Laloë from Laboratoire Kastler Brossel (ENS-Université PSL) in Paris has proposed a new interpretation that could explain many features of the paradox. He sets out a model of this possible theory in a new paper in EPJ D.
My Friend, Albert Einstein
He was one of the greatest scientists the world has ever known, yet if I had to convey the essence of Albert Einstein in a single word, I would choose simplicity. Perhaps an anecdote will help. Once, caught in a downpour, he took off his hat and held it under his coat. Asked why, he explained, with admirable logic, that the rain would damage the hat, but his hair would be none the worse for its wetting. This knack for going instinctively to the heart of a matter was the secret of his major scientific discoveries- this and his extraordinary feeling for beauty.

Gravity is one of the four fundamental forces of nature. It is an immediate fact of
everyday experience, yet it presents us with some of the deepest theoretical and
experimental challenges in contemporary physics. Gravity is the weakest of the four
fundamental forces, but, because it is a universal attraction between all forms of
energy, it governs the structure of matter on the largest scales of space and time,
including the structure of the universe itself
Objects raise hopes of scientists managing to track ‘blobs’ being swallowed by black hole
A number of bizarre shape-shifting objects have been discovered close to the supermassive black hole at the centre of the Milky Way.
The blobs are thought to be giant stars that spend part of their orbits so close to the black hole that they get stretched out like bubble gum before returning to a compact, roughly spherical form.
From Sagan to Tesla, scientists have long puzzled over how to talk to extraterrestrial intelligence.
For the past 200 years, the problem of interstellar communication with an extraterrestrial intelligence has vexed some of the world’s greatest scientists and mathematicians. Carl Friedrich Gauss, the mathematician and inventor of the heliotrope, suggested using a large array of mirrors; Guglielmo Marconi and Nikola Tesla, pioneers of wireless communication, found a solution in radio waves; and John McCarthy and Marvin Minsky, the progenitors of artificial intelligence, wanted to send computers into space as our extraterrestrial envoys.
