The atoms that make up matter never touch each other.
This is because they simply do not interact with the particles that make up matter.
In the earliest moments, one perfect ethereal substance shattered into the diverse spray of particles that make up matter.
Each note in this cosmic symphony would represent one of the many different kinds of particles that make up matter and energy.
We now know that sub-atomic particles come in two varieties: fermions that make up matter, and bosons that carry forces.
In "Madonna of Port Lligat" (1950), in which Gala is cast as the Virgin, everything is in suspension, like the floating atoms that make up matter, and both mother and child are rendered transparent by squares cut in their torsos.
There is sub-atomic physics which deals with the tiny particles that make up matter, and then there is classical mechanics, which deals with the effect on bodies of forces like gravity.
But even though quantum theory tries to describe the tiniest particles that make up matter and how they interact with each other and with energy, experimental quantum computers are anything but small.
The motion of electrons and holes in semiconductors is governed by the theory of quantum mechanics, which was developed during the 1920s and '30s as a much more comprehensive theory of the behaviour of all the elementary particles that make up matter.
Such particles come in two classes: bosons, which convey forces, and fermions, which make up matter.
