Available in PDF, EPUB and Kindle. Book excerpt: In 1935 geneticist Nikolai Timoféeff-Ressovsky, radiation physicist Karl G. Zimmer, and quantum physicist Max Delbrück published “On the Nature of Gene Mutation and Gene Structure,” known subsequently as the “Three-Man Paper.” This seminal paper advanced work on the physical exploration of the structure of the gene through radiation physics and suggested ways in which physics could reveal definite information about gene structure, mutation, and action. Representing a new level of collaboration between physics and biology, it played an important role in the birth of the new field of molecular biology. The paper’s results were popularized for a wide audience in the What is Life? lectures of physicist Erwin Schrödinger in 1944. Despite its historical impact on the biological sciences, the paper has remained largely inaccessible because it was only published in a short-lived German periodical. Creating a Physical Biology makes the Three Man Paper available in English for the first time. Brandon Fogel’s translation is accompanied by an introductory essay by Fogel and Phillip Sloan and a set of essays by leading historians and philosophers of biology that explore the context, contents, and subsequent influence of the paper, as well as its importance for the wider philosophical analysis of biological reductionism.

Book excerpt: Durant cette thèse nous avons caractérisé et amélioré une nouvelle source de rayons X avec unplasma ECR (résonance cyclotronique électronique) permettant de générer des électronsénergétiques de 10 à 120 keV, qui vont ensuite produire le rayonnement X par freinage(bremsstrahlung). Les améliorations de l'installation ont permis d'obtenir une source stable, pouvantfonctionner une journée entière de travail (huit heures) sans arrêt. Dans la première partie de l'étudeexpérimentale on a étudié et déterminé les paramètres optimaux de la source : la pression, lapuissance micro-onde et la configuration magnétique sur le rayonnement X du plasma. Nous avonségalement confirmé la localisation des électrons énergétiques sur un anneau due à la configurationmagnétique. L'intensité trop faible et la zone d'émission non ponctuelle du rayonnement plasma, nepermettant pas l'utilisation de la source à plasma, une cible a été insérée sur la trajectoire desélectrons énergétique pour résoudre ces deux problèmes.Le principal avantage de notre source par rapport aux tubes X, est l'absence de haute tension (20 à400 kV). Pour chauffer les électrons, nous utilisons une onde de 2,45 GHz, qui est la fréquenceindustrielle autorisée dans les fours à micro-ondes, délivrée par un magnétron. Les éléments simplesqui composent notre source donne un coût plus faible qu'un système classique de tubes X, dûprincipalement au prix élevé du générateur HT pour les tubes X. De plus, nous n'avons pas besoind'un vide très poussé car, à la différence des tubes X, la source ECRX fonctionne avec une pressionrésiduelle de 0,1mPa. Et enfin notre source est compacte ce qui la rend facilement transportable. Lesapplications de cette source sont nombreuses comme la radiologie, la stérilisation et le contrôle nondestructif industriel.
