Atomic Weights

The Separation of Chlorine into Isotopes (Isotopic Elements) and the Whole Number Rule for Atomic Weights.

The purpose of this note is to outline a theory elaborated by the author Which appears to afford satisfactory explanation of much of the published data relating to the degradation of carbohydrates by enzyme systems both "in vivo" and "in vitro." Experimental work to test the theory has been in progress for some time' and on completion may necessitate certain modifications. As this is intended t...

Theodore William Richards: apostle of atomic weights and Nobel Prize winner in 1914.

In recognition of his exact determinations of the atomic weights of a large number of the chemical elements, T. W. Richards received the Nobel Prize in Chemistry in 1914. His meticulous techniques resulted in "a degree of accuracy never before attained". This Essay follows Richards from his precocious youth to becoming a celebrated chemist and emphasizes his dedication to forseeing likely sourc...

Weights in block iterative methods

In this paper we introduce a sequential block iterative method and its simultaneous version with op-timal combination of weights (instead of convex combination) for solving convex feasibility problems.When the intersection of the given family of convex sets is nonempty, it is shown that any sequencegenerated by the given algorithms converges to a feasible point. Additionally for linear feasibil...

Multiplicative Weights

In this lecture, we will study various applications of the theory of Multiplicative Weights (MW). In this section, we briefly review the general version of the MW algorithm that we studied in the previous lecture. The following sections then show how the theory can be applied to approximately solve zero-sum games and linear programs, and how it connects with the theory of boosting and approxima...
