How to Tame the Endless Infinities Hiding in the Heart of Particle Physics
...of particles. And more sophisticated incarnations have allowed some physicists to venture further into the murky waters of quantum field theory, and recently string theory. But that’s just the beginning...
How a Human Smell Receptor Works Is Finally Revealed
...detail how smell sensors detect and respond to odor molecules. Yet human smell receptors have resisted attempts to visualize how they work in detail — until now. In a recent...
Is Perpetual Motion Possible at the Quantum Level?
...in equilibrium settings, you couldn’t get time crystals. (05:46) OK, so the recent kind of angle on this work has come from this very different corner of physics, where we’ve...
Physicists Create Elusive Particles That Remember Their Pasts
...recent years researchers have begun using the devices to bend individual qubits to their will. Some physicists consider these efforts simulations, because the qubits inside the processor are abstractions of...
A Plan to Address the World’s Challenges With Math
...he sounds an awful lot like one. “If we take reality exactly as it is, I don’t think we have any real grounds for pessimism,” he said in a recent...
Chatbots Don’t Know What Stuff Isn’t
...don’t expect it to?” Recent studies have finally started to explain the difficulties, and what programmers can do to get around them. But researchers still don’t understand whether machines will...
Flow Proof Helps Mathematicians Find Stability in Chaos
...still far from achieving the perfect picture Mann spoke of: a classification of all the different kinds of Anosov flows. Now, in a series of recent papers, Barthelmé and Mann,...
How Quantum Physicists Explained Earth’s Oscillating Weather Patterns
...begins for the second time, with the relatively recent discovery of the quantum behavior of electrons in topological insulators. In 1980, a quantum physicist named Klaus von Klitzing wanted to...
Selfish, Virus-Like DNA Can Carry Genes Between Species
...inheritance for more than a century: that genes are passed down from parent to child within species. But in more recent years, they have also become aware of genes that...
