Scientists worked with electricity long before they understood that current was made of electrons. The cathode tube was a prime example. By switching on some voltage, scientists could make ...
The question of what protons or neutrons are made up of has an apparently simple answer: quarks and gluons. However, when it ...
The High Energy Stereoscopic System is a ground-based gamma-ray telescope in the highlands of Namibia and sensitive in the ...
A team of researchers has revealed the structure of a modified and evolved version of Photosystem I (PS I), a key protein ...
Astrophysicists have detected the most energetic electrons ever recorded raining down on Earth. With trillions of times the ...
"Understanding these cosmic rays allows us to unveil big particle accelerators in the universe that are often associated with ...
Strong interactions between subatomic particles like electrons occur when they are at a specific energy level known as the ...
A research team has clarified the mechanism behind the generation of runaway electrons during the startup phase of a tokamak ...
The discovery was made by astrophysicists from ... Temperatures this extreme results in electrons not being attached to atomic nuclei, but instead floating around in a so-called ionized plasma.
Whatever his thought process, Mendeleev ultimately arranged the elements according to both atomic weight and valence electrons. Not only did he leave space for elements not yet discovered ...
He discovered the atomic nucleus and developed a model of the atom that was similar to the solar system. Like planets, electrons orbited a central, sun-like nucleus. Acceptance of this model grew ...
