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 ...

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 ...

“At low temperatures, models of reactivity must include the effects of the permanent electric dipoles and quadrupole moments ...

and why the traditional model of the atom is not correct. Electrons are unpredictable - we can't know the path that they travel. Most importantly - they don't orbit the nucleus. For the curious ...

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

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 ...

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 ...

Scientists trying to discover the elusive mass of neutrinos, tiny "ghost particles" that could solve some of the universe's ...

Computers rule the world. We use them in our offices, our factories, and in our smartphones. In research and industry, ...
