The fermions are a class of elementary particles that are defined by their 1/2 integer spin, and the fact that they make up the matter that we interact with everyday.

Fermions are a fundamental class of particles, and they are subdivided into two categories. Together, they serve as the building blocks of all matter.

The neutron is one of the most common particles of matter, and it is integral to the formation of every element other than hydrogen. Find out why.

Fundamental constituents called fermions bind together and form composite particles. These particles constitute most of the mass of atoms.

Beyond the elementary fermions, leptons, and bosons, are the composite particles which are made up of these elementary particles.

When an object with mass moves at a speed approaching the speed of light, it's inherent properties are changed in surprising ways.
