How a "singular hero" helped to open a new field in physics: NPR

Rich Isaacson, seen in his backyard in Pentagon City, Virginia, wrote his thesis on gravitational waves and said he always thought that their existence would be proven sometime during his career. But he did not know that trying to see her would become his career. Ryan Kellman / NPR Hide caption Caption switch Ryan Kellman / NPR Imagine spending 40 …

Tram bowling is an actual sport. Let's take a look at the physics

Last week European tram drivers had their annual championship. They showed their precision when braking. They tried to estimate their speed without the luxury of a speedometer. But by far the most amazing event is tram cones. Yes, tram cones. A tram travels along its route and hits a large stationary ball. This ball then flies away to knock down …

This physics professor explains the "ghostly long-range effect" of the quantum world – Alternet.org

Amar Vutha, University of Toronto Quantum computers, quantum cryptography and Quantum (insert name here) are common in the news these days. Articles about them inevitably refer to the entanglement of a property of quantum physics that enables all these magical devices. Read More: Seven Common Myths on Quantum Physics Einstein called the entanglement "creepy long-range effect", a name that becomes …

Lee Smolin's "Einstein's Unfinished Revolution" examines the problem of quantum physics and reality: NPR

Does reality need realism? If that seems like a strange question to you, keep in mind the fact that this is extremely pressing for physicists and their most successful theory about the physical world. This theory is called quantum mechanics – and every digital electronic device you've ever used owes its existence to the understanding of physics at the atomic …

Discrete-time physics hides in our time-continuous world

Markov processes were used to model the accumulation of piles of sand. Picture credits: Santa Fe Institute Press Scientists believe that time is continuous, not discreet – roughly speaking, they believe that it does not progress into "chunks", but rather runs "smoothly" and smoothly and continuously. Therefore, they often model the dynamics of physical systems as time-continuous "Markov processes," named …

Why twisted graphene is one of the year's most exciting physics stories

A moiré pattern of twisted two-ply graphene. Image: NIST Only a year ago, the scientists presented results that seemed almost too good to be true: carbon plates that were only a single atom thick assumed graphene called a pair of important physical properties, when they are rotated at exactly the right "magic" angle. When the atmosphere at the world's largest …

Epic Games presents an impressive next-generation physics and destruction system in Unreal Engine 4.23 | DSOGaming

At GDC 2019, Epic Games showcased some of the most impressive next-generation physics and destruction systems coming to the latest version of Unreal Engine 4. As Epic Games noted, chaos is the new high-performance physics and destruction of Unreal Engine. The system is made in early access to the Unreal Engine 4.23. The real-time tech demo is embedded in the …

It's Spring Spring Physics explains why time goes by as we age

Credit: CC0 Public Domain A Duke University researcher has a new explanation for why these endless days of childhood seem to last so much longer than they do now – physics. According to Adrian Bejan, J.A. Jones, a professor of mechanical engineering at Duke, believes that this apparent temporal discrepancy can be traced to the slower pace at which images …

New quantum physics experiment suggests that reality is not objective

A new quantum physics experiment provided only one startling idea, which according to the MIT Technology Review was limited to the theory – that under the right conditions two persons could observe the same event, see two different things happen and both are correct. According to research published on Tuesday before the preprint server arXiv, physicists at Heriot Watt University …
