Calculating The Surface Energy of A Deformed Solid
In the deformation of solids, surface energy can be treated as the "energy required to create one unit of surface area", and is a function of the difference between the total energies of the system before and after the deformation: .
Calculation of surface energy from first principles is an alternative approach to measurement. Surface energy is estimated from the following variables: width of the d-band, the number of valence d-electrons, and the coordination number of atoms at the surface and in the bulk of the solid.

“What our children have to fear is not the cars on the highways of tomorrow but our own pleasure in calculating the most elegant parameters of their deaths.”
—J.G. (James Graham)
“I know that the right kind of leader for the Labour Party is a kind of desiccated calculating machine.”
—Aneurin Bevan (1897–1960)
“In the cold of Europe, under prudish northern fogs, except when slaughter is afoot, you only glimpse the crawling cruelty of your fellow men. But their rottenness rises to the surface as soon as they are tickled by the hideous fevers of the tropics.”
—Louis-Ferdinand Céline (1894–1961)
“After the planet becomes theirs, many millions of years will have to pass before a beetle particularly loved by God, at the end of its calculations will find written on a sheet of paper in letters of fire that energy is equal to the mass multiplied by the square of the velocity of light. The new kings of the world will live tranquilly for a long time, confining themselves to devouring each other and being parasites among each other on a cottage industry scale.”
—Primo Levi (1919–1987)
“I should prefer a Woman that is agreeable in my own Eye, and not deformed in that of the World, to a celebrated Beauty. If you marry one remarkably beautiful, you must have a violent Passion for her, or you have not the proper Taste of her Charms; and if you have such a Passion for her, it is odds but it will be imbittered [sic] with Fears and Jealousies.”
—Joseph Addison (1672–1719)
“Rude poets of the tavern hearth,
squandering your unquoted mirth,
which keeps the ground, and never soars,
while jake retorts, and reuben roars;
tough and screaming, as birch-bark,
goes like bullet to its mark;
while the solid curse and jeer
never balk the waiting ear.”
—Ralph Waldo Emerson (1803–1882)
