This frame from "Visualizing the Nucleus" shows animations of four different nuclei, with their protons and neutrons, quarks and gluons visible. NEWPORT NEWS, VA – There has never been a better time ...
Static electricity works because electrons are strongly attracted to protons, right? But, in atoms, electrons are right there, next to the protons in the nucleus. Why don’t the electrons zip directly ...
Big problems sometimes come in small packages. The problem with which physicists must now concern themselves measures a mere 0.0350 millionth of a millionth of a millimetre. This is precisely the ...
The “lead” of a pencil is actually made of a substance called graphite which is made of carbon atoms. The picture shows a close-up of one carbon atom. A hydrogen atom has one proton as the nucleus and ...
When the Nobel Prize-winning US physicist Robert Hofstadter and his team fired highly energetic electrons at a small vial of hydrogen at the Stanford Linear Accelerator Center in 1956, they opened the ...
Using the first new method in half a century for measuring the size of the proton via electron scattering, scientists have produced a new value for the proton's radius in a new experiment. Using the ...

Quantum magnetism: Spin-flip process in atomic nucleus does not account for all magnetic behavior
In the air people breathe, the water on Earth, the stars in the sky and more, atoms are the building blocks that make up the ...
Effective theorists: Sonia Bacca (left), Bijaya Acharya (centre) and Joanna Sobczyk. (Courtesy: Sabrina Hopp/Angelika Stehle) The interaction between an electron and a calcium-40 nucleus has been ...
The atomic nucleus is made up of protons and neutrons, particles that exist through the interaction of quarks bonded by gluons. It would seem, therefore, that it should not be difficult to reproduce ...
