Along with leptons, quarks are basic building blocks of all matter. According to the standard model of particle physics, fermions (quarks and leptons) are the basic constituents of all matter. In the standard model there are six types of quarks and six...

In 1869, Dmitri Mendeleev proposed the periodic law as a method for organizing the known chemical elements in a systematic way. The periodic law was important to chemists because it brought some order into the study of the 50-odd elements then known....

A quark (IPA: /kwɔrk/) is a generic type of physical particle that forms one of the two basic constituents of matter, the other being the lepton. Various species of quarks combine in specific ways to form protons and neutrons, in each case taking...

Why did the scientists chase the top quark? Because they thought it was there. And they apparently were right. The physicists who devoted their careers to the study of subatomic particles may have crossed the last frontier in identifying the final of 12...
