The Solar Orbiter spacecraft, a joint Nasa and European Space Agency (ESA) mission, is set to be launched from Cape Canaveral just after 4am UK time on Monday morning, and will reach its vantage point above the planetary plane by the end of 2021.
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.
The picture, named "The Pale Blue Dot" was obtained on 14th February, 1990, moments before the camera and the several other instruments of the Voyager were powered off for conservation of battery, since the probe wouldn't make a close flyby past any other objects during their lifetime.
As we are human beings, we all are curious – an intrinsic behavior that is associated with us. As any curious being would be, we are also very aware of our environment and the changes that happen to it- we are very good at noticing changes that we even have developed many models and theories
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.
First observations from Inouye telescope bring previously hazy star into sharp focus.
The striking images reveal a surprising level of structure hidden within the churning plasma exterior, bringing a previously hazy impression of the sun’s patchwork surface sharply into focus for the first time.
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
