This is the conservation of energy, and it stands as a bedrock beneath all of physics. It’s a foundation principle that allows us to explain almost every aspect of material existence.

The quantum physicists Sandu Popescu, Yakir Aharonov and Daniel Rohrlich have been troubled by the same scenario for three decades.. It started when they wrote about a surprising wave phenomenon ...

Finally, in December 2020, the trio published a paper in the Proceedings of the National Academy of Sciences explaining what the problem is: In quantum systems, superoscillation appears to violate ...

The process reduces the light’s energy as time passes. “Before Noether’s theorem, the principle of conservation of energy was shrouded in mystery,” the physicist and mathematician Feza Gürsey wrote in ...

Bernoulli’s Equation is one of the cornerstones of fluid dynamics, helping us understand how fluids behave when they move ...

The symmetries of the universe play a fundamental role in shaping the laws of physics. From conservation of energy and momentum to the behavior of particles in quantum fields, symmetries govern ...

According to quantum physics, energy can be 'borrowed' -- at least for some time. Energies lower than zero are possible, much like a bank account that can be overdrawn. There are, however, certain ...

This principle is known as conservation of energy. We know from experience, however, that a roller coaster doesn't keep going forever. Eventually it slows down because of friction (a combination ...

IN an earlier article entitled “Modern Science and Thomas Hobbes”1, I remarked that it was especially the law of conservation of energy which inclined thinkers of the nineteenth century to a ...
