The Static Universe of Walther Nernst
Walther Nernst (1864-1941) was, without a doubt, one of the most remarkable physicists of the early 20th century. His main accomplishments were in the field of physical chemistry, a discipline he founded together with other well-known scientists, including J.H. van’t Hoff, W. Ostwald and S. Arrhenius. His most famous contribution to physics was the so-called third law of thermodynamics, for whi...
متن کاملReciprocal Solubility Influence in Salt Mixtures. the Contributions of Walther Nernst and of Arthur Noyes
In 1887, Walther Hermann Nernst (1864-1941; Nobel Laureate 1920) began his highly successful career as an assistant to Wilhelm Ostwald (1853-1932; Nobel Laureate 1909) at the University of Leipzig. Ostwald strongly supported the ionic theory and had extended it, especially to the dissociation of weak electrolytes. By 1889, Nernst had established the principles of electrode potential, familiariz...
متن کاملWalther Recursion
Primitive recursion is a well known syntactic restriction on recursive deenitions which guarantees termination. Unfortunately many natural deenitions, such as the most common deenition of Euclid's GCD algorithm, are not primitive recursive. Walther has recently given a proof system for verifying termination of a broader class of deenitions. Although Walther's system is highly automatible, the c...
متن کاملDark Matter and Dark Energy
I briefly review our current understanding of dark matter and dark energy. The first part of this paper focusses on issues pertaining to dark matter including observational evidence for its existence, current constraints and the ‘abundance of substructure’ and ‘cuspy core’ issues which arise in CDM. I also briefly describe MOND. The second part of this review focusses on dark energy. In this pa...
متن کاملDark energy with dark spinors
Ever since the first observations that we are living in an accelerating universe, it has been asked what dark energy is. There are various explanations all of which with have various draw backs or inconsistencies. Here we show that using a dark spinor field it is possible to have an equation of state that crosses the phantom divide, becoming a dark phantom spinor which evolves into dark energy....
