One concerns the possibility of including in the pseudopotential relativistic effects to order α2, where α≃1/137 is the fine-structure constant. Kleinman showed that the Hamann–Schlüter–Chiang construction can be generalized to the relativistic case, and that the resulting pseudopotential can ...
It has been a mystery ever since it was discovered more than fifty years ago, and all good theoretical physicists put this number up on their wall and worry about it... It's one of the greatest damn mysteries of physics: a magic number that comes to us with no understanding by man. ...

We study the dependence of the primordial nuclear abundances as a function of the electromagnetic fine-structure constant α, keeping all other fundamental constants fixed. We update the leading nuclear reaction rates, in particular the electromagnetic contribution to the neutron-proton mass difference pe...
The possibility of converting the Baker-Johnson-Adler eigenvalue equationF(α)=0 for the fine-structure constant into a simpler condition is discussed in the framework of the self-consistent (bootstrap) formulation of massless quantum electrodynamics. It is shown that the imposition of a strong co...
Amylose and amylopectin fine structure Amylose and amylopectin (Fig. 1) have different structures and properties which have been discussed and reviewed by many authors (French, 1972, Banks and Greenwood, 1975, Lineback, 1984, Lineback, 1986, Swinkels, 1985, Gallant and Bouchet, 1986, Blanshard,...
