It’s been 100 years since a young German unlocked the mysteries of quantum mechanics. See how that gave us smartphones, GPS, MRIs. See what’s next.

In the eighty years since of the atomic bombings of Japan dozens of opportunities to halt the macabre march of nuclear ...

The melting of crystals is the process by which an increase in temperature induces the disruption of the ordered crystalline ...

1. Convert kilograms/second to grams per second. 1 kg = 1000 grams. If the mass flowrate is 0.25 kilograms/second, convert this to 250 grams/second. 2. Convert grams to moles, using the molar mass of ...

A high-energy photonic jet (white and blue) blasts through a collapsar with a black hole at its center. The red space around ...

Highly charged heavy ions form a very suitable experimental field for investigating quantum electrodynamics (QED), the ...

New research suggests that the theoretical Hawking radiation generated by black holes may have influenced the early structure ...

However, it is widely believed that in the early universe, much smaller black holes — each with a mass of less than 100 tons — could have formed. These so-called primordial black holes would ...

ABSTRACT: We establish quantum circuit complexity as a fundamental physical observable and prove that it satisfies an uncertainty relation with energy, analogous to Heisenberg’s canonical uncertainty ...

One feature of quantum theory devised in 1955 predicts that empty ... and composed of 5 percent atomic matter, 25 percent dark matter and 70 percent dark energy. But the model fails to say what ...

Dark matter could be an entire dark sector of the universe, with its own particles and forces H ave you ever stood by the sea ...

ENGLISH readers will welcome this authoritative account by Prof. Bohr of the application of his theory to atomic structure. The essay has been translated from the Zeitschrift fur Physik by L.
