Josh Hafner USA TODAY Published 12:49 p.m. UTC Sep 6, 2018 Quantum physics has an answer for the age-old conundrum: Which came first, the chicken or the egg? Possibly both. The philosophical dilemma first posed in Ancient Greece has had biologists thinking egg. But physicists from Australia and France are looking at the riddle a different way, using it to explain their findings on how events unfold on the smallest of scales. “The weirdness of quantum mechanics means that events can happen without a set order,” Jacqui Romero, a University of Queensland researcher, said in a statement. Take a daily commute, she said, in which a person hops on a train before riding a bus to the office. The train ride must occur first, then the bus. That's the set order. Not so in quantum physics, Romero said. “In our experiment, both of these events can happen first," she said. "This is called 'indefinite causal order' and it isn’t something that we can … [Read more...] about Which came first, the chicken or the egg? Both, quantum physics says
Behind the Screen, By Kathryn Whitney Boole| “Ant-Man and the Wasp” is more than just a carefree romp with your favorite stars wearing action hero suits. Try not to see this when you’re dead tired or after you’ve been at happy hour with your friends, because there’s a lot going on that you could miss if your senses aren’t sharp. The comedic timing of the actors is brilliant and the narrative is rapid-fire and I don’t want to ruin your experience by describing it in detail. Just be ready for a lot of double takes and hilarious confused identity scenes. It may have you questioning how much you prejudge people and animals by their looks and sounds. The story of Ant-Man is built around the concepts of Quantum Physics, which (in an extremely simplified definition) state that everything in the universe has both particle nature and wave nature at the same time, and that there is possibility of existing in more than one plane at the same time. The … [Read more...] about The Quantum Physics of Laughter

The Unfinished Quest for the Meaning of Quantum Physics Are atoms real? Of course they are. Everybody believes in atoms, even people who don’t believe in evolution or climate change. If we didn’t have atoms, how could we have atomic bombs? But you can’t see an atom directly. And even though atoms were first conceived and named by ancient Greeks, it was not until the last century that they achieved the status of actual physical entities — real as apples, real as the moon. The first proof of atoms came from 26-year-old Albert Einstein in 1905, the same year he proposed his theory of special relativity. Before that, the atom served as an increasingly useful hypothetical construct. At the same time, Einstein defined a new entity: a particle of … [Read more...] about What Does Quantum Physics Actually Tell Us About the World?
Tech & Science Quantum Physics Information Security Our world is all about information, so perhaps it's no surprise that quantum physicists think about how they can manipulate their field to send information faster. And in a pair of recent papers, a team of quantum scientists have outlined a way to do just that—and in a way that no wannabe spy could ever listen in on. The gist of the technique feels a bit like the famous riddle in which two guards—one of whom always tells the truth and one of whom always lies—protect two doors, one of which hides a tiger. The trick is to always ask what the other guard would say: that way, it doesn't matter whether you've asked the truthful guard or the lying one, you have precisely one lie and one truth in the answer, so you can work backwards to avoid the tiger. The physicists' technique could mean information can travel twice as fast—with complete security.

Tech & Science Planets Black Holes galaxies Quantum mechanics is concerned with the behavior of the tiniest of particles, and usually the mathematics behind it is relegated to this tiny realm. Now, a researcher from the California Institute of Technology has used a fundamental quantum physics equation to understand huge self-gravitating space disks. Konstantin Batygin, an assistant professor at Caltech, has discovered that the changing shapes of spinning disks of matter around massive astronomical objects like black holes can be described by the Schrödinger equation. The evolution of these disks has stumped astrophysicists for many years. Swarming matter An artist's impression of the research, published in Monthly Notices of the Royal Astronomical Society.
