A parasite pioneer

A parasite pioneer

The concept that infectious biological agents were responsible for many diseases was controversial in the midnineteenth century. But key experiments by famed scientists such as Louis Pasteur and Robert Koch eventually won over sceptics. However, some other researchers, equally convinced by this notion, and who also carried our convincing experiments in its support at the same time, have failed ...

Lotfi Zadeh: a Pioneer in AI, a Pioneer in Statistical Analysis, a Pioneer in Foundations of Mathematics, and a True Citizen of the World

Everyone knows Lotfi Zadeh as the Father of Fuzzy Logic. There have been – and will be – many papers on this important topic. What I want to emphasize in this paper is that his ideas go way beyond fuzzy logic: • he was a pioneer in AI; • he was a pioneer in statistical analysis; and • he was a pioneer in foundations of mathematics. My goal is to explain these ideas to non-fuzzy folks. I also wa...

Pioneer effect ” : A cosmological Foucault ’ s experiment

The reported anomalous acceleration acting on the Pioneers space-crafts could be seen as a consequence of the existence of some local curvature in light geodesics when using the coordinate speed of light in an expanding space-time. We will show that, as a matter of fact, what has been detected in the experiments is just the cosmic expansion rate-the Hubble parameter H-, a feature of light signa...
