Schrödinger equation allows us to write the complete wave equation described by radial an harmonic spherical terms, so, the following work contents are a study of the probability of electron existence in the hydrogen atom, as well the probability of current density resulting as a consequence of these descriptions. Since the wave function can be written in terms of operators the calculation on the relevant operator determined their influence on the particle number which lead to the conclusion that one can write the fields in terms of creation operator and annihilation operator, and this step...

March 1902, William Bateson signed his dissertation "Mendel's Principles of Heredity", Bateson needed to read Mendel's paper during the brief journey in London in 1900 which would change profoundly his world. Bateson had a new mission in life. He understood that the mystery of inheritance had been solved. He soon became a relentless apostle of Mendel's laws of inheritance. A few years later in 1905, Bateson coined the term genetics, and the genetics revolution had begun. Mendel proposed that the factors that control traits act like particles rather than fluids and that these particles do not...

Les travaux présentés dans ce livre concernent l'interaction des champs quantiques avec le fond classique manifesté par un champ externe puissant. En d'autres termes, le champ d'arrière-plan est décrit de manière adéquate par une théorie classique et n'a pas besoin d'être quantifié. Une simplification importante est obtenue en considérant que le champ scalaire quantifié n'interagit qu'avec le champ gravitationnel. La renormalisation à l'aide de la méthode de la fonction zêta est l'exigence essentielle de cette étude pour calculer les valeurs d'espérance du tenseur...
