When we look out at the universe – even with the most powerful of telescopes – we can only see a fraction of the matter we know must be there. In fact, for every gram's worth of atoms in the universe, there is at least ...

The merging of the electromagnetic and the weak and strong nuclear force into one single force has been a holy grail for physicists for a long time. Mathematical physicist Walter van Suijlekom now shows this so-called 'grand ...

Neutrons are notoriously slippery subatomic particles. On their own, they break down in a matter of minutes, but within the confines of the atom's nucleus, neutrons are a foundational piece of nearly all known types of matter ...

Precise information about the magnetic properties of nuclei is critical for studies of what's known as the 'weak force.' While people do not feel this force in the same way they feel electricity or gravity, its effects are ...

Conduction and thermal radiation are two ways in which heat is transferred from one object to another: Conduction is the process by which heat flows between objects in physical contact, such as a pot of tea on a hot stove, ...
