atomic theory n 1.(Atomic Physics) any theory in which matter is regarded as consisting of atoms, esp that proposed by John Dalton postulating that elements are composed of atoms that can combine in definite proportions to form compounds ...
the particle theory of matter was taught with a constructivist conceptual change inquiry approach to a group of middle years' students. The students' dialogues on the particle theory of matter, which took place on a web discussion board, were analyzed and then classified into types of dialogues....

The discovery of the W and Z particles—also referred to as intermediate vector bosons—confirmed the electroweak theory, the joint framework describing the electromagnetic and weak forces. The existence of intermediate vector bosons and their properties were predicted in the late 1960s by the ...
A theory of the model-space nuclear single-particle potential U is proposed, where the condition for determining U is that the one-body part of the resulting model-space effective interaction vanishes. Preliminary application to nuclear matter calculations has been made. It has led to a continuous...
According to theory, the top quark carries a charge of 2/3e; its partner, the bottom quark, has a charge of −1/3e. In 1995 two independent groups of scientists at the Fermi National Accelerator Laboratory reported that they had found the top quark. Their results give the top quark a...
In 1973 the concept of colour as the source of a “strong field” was developed into the theory of QCD by European physicists Harald Fritzsch and Heinrich Leutwyler, together with American physicist Murray Gell-Mann. In particular, they employed the general field theory developed in the 1950s...
