Hard spheres are widely used as model particles in the statistical mechanical theory of fluids and solids. They are defined simply as impenetrable spheres that cannot overlap in space. They mimic the extremely strong repulsion that atoms and spherical molecules experience at very close distances. Hard spheres systems are studied by analytical means, by molecular dynamics simulations, and by the experimental study of certain colloidal model systems.

Famous quotes containing the words hard and/or spheres:
“On a huge hill,
Cragged, and steep, Truth stands, and he that will
Reach her, about must, and about must go;
And what the hill’s suddenness resists, win so;
Yet strive so, that before age, death’s twilight,
Thy Soul rest, for none can work in that night.
To will, implies delay, therefore now do:
Hard deeds, the body’s pains; hard knowledge too
The mind’s endeavours reach, and mysteries
Are like the Sun, dazzling, yet plain to all eyes.”
—John Donne (1572–1631)
“It launch’d forth filament, filament, filament, out of itself,
Ever unreeling them, ever tirelessly speeding them.
And you O my soul where you stand,
Surrounded, detached, in measureless oceans of space,
Ceaselessly musing, venturing, throwing, seeking the spheres to connect them,
Till the bridge you will need be form’d, till the ductile anchor hold,
Till the gossamer thread you fling catch somewhere, O, my soul.”
—Walt Whitman (1819–1892)
