High-Speed Photography Turns Water Droplets Into Liquid Sculptures The water droplet is the quintessential cliché of high-speed photography. Any Internet search will produce a dizzying number of bursting and rippling liquid surfaces. Yet in the right hands, even the familiar can be extraordinary. Markus Reugels, a German amateur photographer who has perfected the theme, has produced an exhaustive catalog of his favorite subject captured in every conceivable, fleeting pose. Astrophysicists on the Verge of Spotting Gravitational Waves Gravitational waves are ripples in the fabric of spacetime caused by cataclysmic events such as neutron stars colliding and black holes merging. The biggest of these events, and the easiest to see, are the collisions between supermassive black holes at the centre of galaxies. So an important question is how often these events occur. Today, Sean McWilliams and a couple of pals at Princeton University say that astrophysicists have severely underestimated the frequency of these upheavals. Their calculations suggest that galaxy mergers are an order of magnitude more frequent than had been thought. Consequently, collisions between supermassive black holes must be more common too.
Responsive email design tools comparison Email design has come a long way since the old days of plain-text messages. In this series we’ve looked at the various problems we have to deal with when building emails and a new approach; the responsive email design framework. Now we’ll discuss some of the best methods, the benefits of each one, and which is best for the task you’ve been given. Black hole A black hole is defined as a region of spacetime from which gravity prevents anything, including light, from escaping. The theory of general relativity predicts that a sufficiently compact mass will deform spacetime to form a black hole. Around a black hole, there is a mathematically defined surface called an event horizon that marks the point of no return. The hole is called "black" because it absorbs all the light that hits the horizon, reflecting nothing, just like a perfect black body in thermodynamics. Quantum field theory in curved spacetime predicts that event horizons emit radiation like a black body with a finite temperature. This temperature is inversely proportional to the mass of the black hole, making it difficult to observe this radiation for black holes of stellar mass or greater.
How Bill Nye Became The Science Guy. And A Ballet Shoe Inventor. And a Political Voice When Bill Nye tells a story about getting hit in the head, he stops to remind you about inertia, “a property of matter.” He’ll ask you how many electric switches are in your iPhone and casually chat about SpaceShipOne. It seems as though Nye were born to play the role for which he is best known: “the science guy,” an amusing, bow-tie-wearing teacher with an entertaining experiment to go with every scientific phenomena. But his career trajectory reads much more like a delicate string of happenstance than a born destiny. Looking a bit like Steve Martin started his career as a comic.
Every Black Hole Contains Another Universe? According to a mind-bending new theory, a black hole is actually a tunnel between universes—a type of wormhole. The matter the black hole attracts doesn't collapse into a single point, as has been predicted, but rather gushes out a "white hole" at the other end of the black one, the theory goes. (Related: "New Proof Unknown 'Structures' Tug at Our Universe." ) In a recent paper published in the journal Indiana University physicist Nikodem Poplawski presents new mathematical models of the spiraling motion of matter falling into a black hole. His equations suggest such wormholes are viable alternatives to the "space-time singularities" that Albert Einstein predicted to be at the centers of black holes. According to Einstein's equations for general relativity, singularities are created whenever matter in a given region gets too dense, as would happen at the ultradense heart of a black hole.
Support In a Nutshell – Kurzgesagt creating Science Animation Videos Hi Everybody! Who are we? almost two years ago we started doing videos on youtube. We did not think this would be a permanent thing, it kind of just happened. Apollo 11 Broadcast on live TV to a world-wide audience, Armstrong stepped onto the lunar surface and described the event as "one small step for [a] man, one giant leap for mankind." Apollo 11 effectively ended the Space Race and fulfilled a national goal proposed in 1961 by the late U.S. President John F. Kennedy in a speech before the U.S.
Um, Maybe You Shouldn't Have Hidden From the Zombies in That Church... I keep posting in these but of course you keep deleting my opinions. You can't just change the definition of the phrase "fine art" because you like this art. It's skilled art, it's great art, hell maybe it's even "high art," but fine art is a thing and this is not that thing. That doesn't mean it's less creative or beautiful than other art, but it is not fine art.
Quantum gravity takes singularity out of black holes - space - 29 May 2013 Falling into a black hole may not be as final as it seems. Apply a quantum theory of gravity to these bizarre objects and the all-crushing singularity at their core disappears. In its place is something that looks a lot like an entry point to another universe. Most immediately, that could help resolve the nagging information loss paradox that dogs black holes. Though no human is likely to fall into a black hole anytime soon, imagining what would happen if they did is a great way to probe some of the biggest mysteries in the universe. Most recently this has led to something known as the black hole firewall paradox – but black holes have long been a source of cosmic puzzles.
