Juan Maldacena, Pondering Quantum Gravity by the Pond
...or out — in clearing a path to inspiration. As a young professor at Harvard University in 1997, Juan Maldacena reshaped fundamental physics with the discovery that, as he put...
A New Twist Reveals Superconductivity’s Secrets
...with simple ratios that seemed impervious to the increasing complexities of the thicker systems. “Especially in condensed matter physics, you think that you’re doing something very close to physical or...
Astronomers Creep Up to the Edge of the Milky Way’s Black Hole
...— is spinning not far from the innermost orbit allowed by the laws of physics. If so, this affords astronomers their closest look yet at the funhouse-mirrored space-time that surrounds...
Inside the Proton, the ‘Most Complicated Thing You Could Possibly Imagine’
...charged particle at the heart of every atom, physicists are still struggling to fully understand the proton. High school physics teachers describe them as featureless balls with one unit each...
Why This Universe? A New Calculation Suggests Our Cosmos Is Typical.
...for Theoretical Physics in Waterloo, Canada, for the same reason that air spreads evenly throughout a room: Weirder options are conceivable, but exceedingly improbable. The universe “may seem extremely fine-tuned,...
Physicists Pin Down Nuclear Reaction From Moments After the Big Bang
...physics, nuclear physics, cosmology and astronomy,” he said. The reaction involves deuterium, a form of hydrogen consisting of one proton and one neutron that fused within the cosmos’s first three...
Computer Scientists Prove That Heat Destroys Quantum Entanglement
...physics compete with the laws of thermodynamics, and things get messy. At very low temperatures, entanglement can spread over long distances, enveloping many atoms and giving rise to strange phenomena...
