On the page the random atoms of existence assemble themselves into a Seurat.
In the random atomic order of a glassy solid, the atoms are packed less densely than in a corresponding crystal, leaving larger interstitial spaces, or holes between atoms.
He thought heat was caused by the random motion of atoms, and that all of thermodynamics could be explained in those terms.
These can be anything that destroys the local perfection of the atomic arrangement for example, impurity atoms, grain boundaries, or the random oscillation of atoms induced by thermal energy.
The work starts with two streams of dancers (more ravishingly lighted than ever by James F. Ingalls) hurtling past one another on bisecting diagonals, like random atoms, until at last two collide and pause: a molecule.
Atoms of the same kind can trade places and can wander through the liquid by the random-walk process called diffusion.
The probabilistic element is introduced by a random choice of transverse coordinates and velocities of the projectile at the crystal entrance as well as by accounting for the random positions of the atoms due to thermal vibrations.
Heat is defined, after all, as the random movement of atoms.
Yet clearly there are random events in Nature, and a vast body of science is based on them, from the random collision of atoms to the random mutations that drive Darwinian evolution.
This process involves the random replacement of an atom in a mineral by a foreign atom of similar ionic radius and valence, without changing the atomic packing of the host mineral.
