Sir Anthony Leggett obituary: theoretical physicist

Tony Leggett lecturing on Schrödinger's cat at the Loomis Laboratory, University of Illinois Urbana-Champaign, circa 1985.

Anthony Leggett not only made a name for himself as a pioneering academic physicist but in 2003 he shared the Nobel Prize in physics for his research on superfluidity and the theory of superfluidity. However, he had left science at school as something “incomprehensible” – especially physics, which “knows in one ear and out the … Read more

Physicists Discover Something That Can Travel Faster Than Light: The Darkness Inside It

YouTube Thumbnail

For the first time, physicists have discovered that ‘holes’ of light can travel faster than light itself. They are known as phase singularities or optical vortices, and since the 1970s, scientists have predicted that, just as the eddies in the river can move faster than the water flowing around them, so can the waves of … Read more

100 years on, Quantum physics remains the universe's biggest mystery - Iowa Park Leader

A century later, the quantum the land is still incredibly productive and stubborn a miracle. Its equations are parallel laser devices and LEDsguide the MRI scanner, and underwrite the transistors that heat up our phones, yet leave us confused as to what numbers it really tells us about the truth. The theory predicts about amazing … Read more

A New Theory Says We Have Been More Than Others

A picture of Cosmic Inflation

One of the biggest unsolved problems in physics has to do with combining quantum mechanics and general relativity – two theories that are equally successful. And the latest attempt to close the bridge brings into the equation the explosion that started everything: the Big Bang. In a recent paper in Physical Review Letters, physicists at … Read more

Oh No! Evanston Residents Worry About Big Betty, Their Moose Friendly Neighbor

Big Betty, a moose in the Evanston neighborhood, as she appeared on April 1. A large patch of exposed skin on his side may look scary, but Wyoming Game and Fish staff saw no signs that the moose was sick, injured, or dying.

What happened to Big Betty? Evanston residents are concerned that their area’s moose are looking worse for wear this spring. Big Betty is a moose known to many who live in this southwestern Wyoming town. They often find it resting in their yard, sometimes with a calf next to it. When Shasta Sharp saw Big … Read more

A national park ranger photographs rare species for the first time while snorkeling on the job

Community park researcher Michael Reichmuth stands in front of a tree-filled space

Michael Reichmuth, a fisheries biologist for the National Park Service, often dives in the cold waters of San Francisco Bay Area parks and beaches. Most of the time, he is busy at work, monitoring the endangered coho salmon. He’s been here for over 20 years, according to the NPS article, so he’s seen a lot … Read more

"They were inseparable, like a passionate couple, sharing every moment together." 7 romantic, most loved animals in the world | Find Wildlife

Animals are driven by passion – whether it’s the lasting bonds that last a lifetime like swans or the short, intense, fleeting, stormy love of snow leopards, finding a mate is an important part of being alive. We’ve collected some of the best stories of love and attraction from the world of wildlife. The most … Read more

Discovery of Rare Gravitational Wave May Hold Key to First Evidence of Primordial Black Holes

Primordial Black Holes Natu 940x529

researchers may have found the first direct evidence of ancient black holes, which could revolutionize our understanding of dark matter. A gravitational wave, captured by LIGO in November 2025proposed a revolutionary hypothesis: the collision that produced the signal may not have involved ordinary black holes in stars, but rather black holes formed in the early … Read more

Why do Supermassive Black Holes grow so slowly?

This artist's drawing shows a black hole surrounded by a ring of accretion. When the material inside these rings heats up they emit x-rays. Observing these x-rays is an important part of measuring SMBH and AGN. In this simulation, SMBH also launches a jet. Image credit: NASA/JPL-Caltech

When our powerful infrared telescopes allowed astronomers to look further into the future, they made some amazing discoveries. One of them involves supermassive black holes (SMBH), the physics-defying behemoths at the center of massive galaxies such as the Milky Way. In fact, the SMBH grew much faster in the jewelry world than it does in … Read more
