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.”

“O! I must tell you that I have fallen in love with a gentleman whom I have lately come acquainted with: he is about 60 or 70has the misfortune to be humpbacked, crooked legged, and rather deformed in his face.But, in sober sadness, I am delighted with the Dean of Coleraine, whose picture this is, and which I have very lately read. The piety, the zeal, the humanity, goodness and humility of this charming old man have won my heart. Ah! who will not envy him the invaluable treasure!”
