The year 1949 saw the publication of two papers by Peter Bergmann: Non-Linear Field Theories in the Physical Review [1] and, together with Johanna Brunnings, in the Reviews of Modern Physics [2], with the ambitious title Non-Linear Field Theories II: Canonical Equations and Quantization. These papers lay the foundation for the research of the Syracuse group working to quantize Einstein's theory...

wartime employment opportunities for some blind persons or members of their families with marginal employability ended with the war. As a result, many blind persons turned to public assistance for their maintenance. Other factors have undoubtedly contributed to the increase in the number of persons receiving aid to the blind. Among these is the increase in the total population, particularly the...

Chris Marshall Chris Marshall, who died on August 8 at age 66, was a world-renowned cell biologist best known for his pioneering contributions to oncogene research and to cell signaling via GTPases, especially to our understanding of tumor cell signaling through the Ras-Raf-Mek-Erk pathway. He spent the whole of his independent research career at the Chester Beatty Laboratories of the Institute...

In this paper, I want to characterize Wittgenstein’s epistemology, namely his contextualism, presented in his notes published under the title On Certainty. This characterization will be made in terms of a comparison with four control points in order to put into light the peculiarities of Wittgenstein’s epistemological position. The markers I will use for that purpose will give an indication of ...

Susan Lindquist was internationally renowned for her pioneering discoveries that transformed our understanding of protein homeostasis and the wide array of biological processes it governs. She developed cutting-edge genetics and cell biology technologies; applied them on diverse organisms, including yeast, fruit flies, plants, cavefish, and humans; and tackled and solved previously intractable ...
