How many times can I half the distance between my hands? Assume perfect coordination and the ability to localize my palms to the quantum level. 15 halvings gets…

Quantum computers aren’t the next generation of supercomputers—they’re something else entirely. Before we can even begin to talk about their potential applications, we need to understand the fundamental physics that drives the theory of quantum computing.…

Microchips are one of the most complicated objects humanity has created, packing billions of transistors into a chip only a few centimeters across. These transistors keep getting smaller and more efficient, and the current process to make chips is already…

Entropy is surely one of the most perplexing concepts in physics. It’s variously described as a measure of a system’s disorder - or as the amount of useful work…

Even in an incomplete state, quantum field theory is the most successful physical theory ever discovered. Nathan Seiberg, one of its leading architects, reveals where math and QFT converge. Read more at Quanta: https://www.quantamagazine.org/nathan-seiberg…

Decades after the landmark proof of Fermat’s Last Theorem, ideas abound for how to make it even more reliable. But such efforts reflect a deep misunderstanding of what makes the proof so important.

Adversarial Examples have long been a fascinating topic for many Machine Learning researchers. How can a tiny perturbation cause the neural network to change its output by so much? While many explanations have…

Physicists at MIT and elsewhere have used gravitational waves to observationally confirm Hawking’s black hole theorem for the first time.

1905年爱因斯坦提出狭义相对论后，受到不少科学家的批评，然而，只有爱因斯坦自己找到了狭义相对论的真正困难：既没有办法定义惯性系，也没有办法把引力纳入到相对论的框架内。在格罗斯曼、希…

Inevitably, life on Earth will come to an end, whether by climate disaster, cataclysmic war, or the death of the sun in a few billion years. What do we do about it?

New work suggests that the radiolytic splitting of water supports giant subsurface ecosystems of life on Earth — and could do it elsewhere, too.

Lucie Green takes us on a journey from the centre of the sun to planet earth in a run-down of the latest solar physics research.
