There were hints that the world may be quantum long before the development of quantum mechanics in 1925 – could we have come up with this revolutionary theory hundreds or even thousands of years ...

Quantum effects like superposition and entanglement have long been seen in single particles, but physicists are on a quest to find out just how big an object can be before it loses its quantumness ...

Particle-accelerator study focuses on the r-process thought to be responsible for forming elements heavier than iron ...

In a nutshell Scientists have developed a powerful new microscope called SMART-EM that can record real-time videos of individual atoms and molecules during chemical reactions, something that was ...

As if atoms weren’t already mind-blowingly small, never mind subatomic particles, CERN researchers in the CMS Collaboration ...

Quarks are the reason protons have a positive charge. Each quark has a fraction of an electric charge. A proton has two up ...

April 14, 1932 was a day that transformed subatomic physics forever as a lithium atom was split using a proton beam.

H2O. An almost negligible proportion of a few per million consists of "heavy water," in which the hydrogen atoms (H) are ...

Each day, a human adult loses on average 50 to 70 billion cells, which die from natural causes alone. New cells replace lost ...

Atomic clocks have long been the gold standard for measuring time and frequency. Among them, optical clocks—using atoms like strontium or aluminum—have reached staggering levels of accuracy, with ...

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 ...
