Physicists long believed time was a basic feature of the universe. But it may just emerge from cosmic information.

A century ago, Erwin Schrödinger came up with an equation that says how the quantum world behaves. Now scientists are asking ...

The way time ticks forward in our universe has long stumped physicists. Now, a new set of tools from entangled atoms to black ...

Abstract: In this paper, a mesh-free method based on physicsinformed neural network (PINN) is presented for time-domain electromagnetic simulations. This PINN method employs the weighted Laguerre ...

Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at ...

As the Dark Energy Survey (DES) releases its final results, we caught up with two physicists who've been involved in the ...

A long-standing law of thermodynamics turns out to have a loophole at the smallest scales. Researchers have shown that quantum engines made of correlated particles can exceed the traditional ...

When quantum spins interact, they can produce collective behaviors that defy long-standing expectations. Researchers have now shown that the Kondo effect behaves very differently depending on spin ...

All celestial bodies—planets, suns, even entire galaxies—produce magnetic fields, affecting such cosmic processes as the ...

The restart of classes at Brown comes a month after a 48-year-old former student opened fire inside a campus engineering building on December 13, killing two people.

Analyze an uphill skier problem using work, energy, and power principles. See how gravitational potential energy, applied force, and friction determine the required work and power, and learn how speed ...

Solve the classic blob jump physics problem using the Work–Energy Theorem. Follow how gravitational potential energy, kinetic energy, and energy transfer explain the launch speed and maximum height, ...
