Atoms are the building blocks of all matter, from the air we breathe to every cell in our bodies. Yet despite their presence everywhere, no one has truly seen an atom with the naked eye ,until ...

The Geiger-Marsden experiment, also called the gold foil experiment or the α-particle scattering experiments, refers to a series of early-20th-century experiments that gave physicists their first ...

In this diagram of methane (CH₄) the chemical bond between atoms is shown as a stick. One molecule of the compound methane is made from one carbon atom and four hydrogen atoms.

This, however, is probably a secondary effect resulting from the primary expulsion of a β particle from the nucleus. In 1913, only the barest outlines of the structure of the atom had been drawn.

Even the smallest defects can create serious problems. It's a good thing, then, that researchers have found a way to map nanoparticles at an "unprecedented" level of detail -- they've located the ...

Diagrams with no loops have amplitudes of weight 0; the amplitudes of diagrams with one loop are all periods of mixed Tate motives and have, at most, a weight of 4.

Physicists have measured an extremely rare particle decay inside the world's largest atom smasher — a discovery that bolsters the leading model of particle physics and leaves little room for ...
