Pierre-François Olive Rayer: Biography

Writing in 1932, Dr. Raymond Molinéry described the renowned French physician Pierre-François Olive Rayer (1793–1867) as having had the misfortune to have been born and to have lived through tempestuous times, when intrigue and violent uprisings were happy bed-fellows. It would seem appropriate then, before setting out details of the life and professional achievements of this ‘‘good, gentle, af...

According to biomolecular data, the great apes split into Asian pongids (orang-utan) and African hominids (gorillas, chimpanzees and humans) 18–12 million years ago (Mya) and hominids split into gorillas and humans–chimpanzees 10–6 Mya. Fossils with pongid features appear in Eurasia after c. 15 Mya, and fossils with hominid fossils appear in Africa after c.10 Mya. Instead of the traditional sav...

Assignment 3 François Séguin

Question 1 First, we have that λ − λ − 2 = (λ + 1)(λ − 2). Therefore, it is true that the eigenvalues of the corresponding adjacency matrix come in pairs of additive inverse. However, notice that ± √ −1 are eigenvalues, and therefore the associated matrix cannot be symmetric (there would only be real eigenvalues). We conclude that no undirected graph can have the above characteristic polynomial...

The Planck mission François

These lecture notes discuss some aspects of the Planck1 mission, whose prime objective was a very accurate measurement of the temperature anisotropies of the Cosmic Microwave Background (CMB). We announced our findings a few months ago, on March 21st , 2013. I describe some of the relevant steps we took to obtain these results, sketching the measurement process, how we processed the data to obt...
