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)
“Because relationships are a primary source of self-esteem for girls and women, daughters need to know they will not lose our love if they speak up for what they want to tell us how they feel about things. . . . Teaching girls to make specific requests, rather than being indirect and agreeable, will help them avoid the pitfalls of having to be manipulative and calculating to get what they want.”
—Jeanne Elium (20th century)
“The surface of the earth is soft and impressible by the feet of men; and so with the paths which the mind travels. How worn and dusty, then, must be the highways of the world, how deep the ruts of tradition and conformity!”
—Henry David Thoreau (1817–1862)
“But often the presence of mind and energy of a person remote from the spotlight decide the course of history for centuries to come.”
—Stefan Zweig (18811942)
“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)
“Without [diversion] we would be in a state of weariness, and this weariness would spur us on to seek a more solid means of escaping from it. But diversion amuses us, and leads us unconsciously to death.”
—Blaise Pascal (1623–1662)
