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.

“[The] elderly and timid single gentleman in Paris ... never drove down the Champs Elysees without expecting an accident, and commonly witnessing one; or found himself in the neighborhood of an official without calculating the chances of a bomb. So long as the rates of progress held good, these bombs would double in force and number every ten years.”
—Henry Brooks Adams (18381918)
“Sin in this country has been always said to be rather calculating than impulsive.”
—Frank Moore Colby (18651925)
“All forms of beauty, like all possible phenomena, contain an element of the eternal and an element of the transitoryof the absolute and of the particular. Absolute and eternal beauty does not exist, or rather it is only an abstraction creamed from the general surface of different beauties. The particular element in each manifestation comes from the emotions: and just as we have our own particular emotions, so we have our own beauty.”
—Charles Baudelaire (18211867)
“I rather think the cinema will die. Look at the energy being exerted to revive ityesterday it was color, today three dimensions. I dont give it forty years more. Witness the decline of conversation. Only the Irish have remained incomparable conversationalists, maybe because technical progress has passed them by.”
—Orson Welles (19151984)
“The sense of an entailed disadvantagethe deformed foot doubtfully hidden by the shoe, makes a restlessly active spiritual yeast, and easily turns a self-centred, unloving nature into an Ishmaelite. But in the rarer sort, who presently see their own frustrated claim as one among a myriad, the inexorable sorrow takes the form of fellowship and makes the imagination tender.”
—George Eliot [Mary Ann (or Marian)
“Manuel showed her his open hand: Look at this finger, how meager it seems, and this one even weaker, and this other one no stronger, and this one all by himself and on his own.
Then he made a fist: But now, is it strong enough, big enough, solid enough? It seems so doesnt it?”
—Jacques Roumain (19071945)
