Wolfgang Pauli (1900–1958)

Wolfgang Pauli was a brilliant theoretical physicist responsible for positing the Pauli Exclusion Principle and the winner of the 1945 Nobel Prize in Physics. However, at the first printing of this book, Pauli was a young man of 21. I really admire that sort of thing, to be able to publish something like this at that age. The book acknowledges that there are issues with its contents since it was printed in 1921, but this book does a fine job of showing off relativity as it was known at that show more time.

Theory of Relativity is split into five major parts. They are as follows.

In part I, Pauli begins by defining the History of the Special Theory of Relativity. You know, the one that states that the speed of light is constant in all reference frames and that the laws of physics are the same for all inertial systems. This section of the book also discusses the consequences of that idea, the Lorentz Contraction and time dilation. Although this part of the book does have some equations that use curl and div, not many of them are shown.

With part II, we are introduced to some mathematical tools to help us on our journey to understand relativity. This section introduces the idea of "space-time," a four-dimensional manifold that is our reality. So Pauli starts to talk about transformation groups and using tensor calculus for affine transformations. Pauli demonstrates the basic ideas of tensor algebra and how to use them to anticipate the final results we are trying to find and the ideas of Riemannian Geometry to account for space-time curvature.

Part III elaborates on the Special theory a little bit more, taking care to discuss Kinematics, Electrodynamics Mechanics, and Thermodynamics in a relativistic manner.

Part IV discusses the General Theory in all its glory.

Part V is called Theories on the Nature of Charged Elementary Particles.

In total, Theory of Relativity contains 499 equations, some of them with those old-timey German Script letters that I believe to relate to a field. It also contains a ton of notes which are further discussed at the end of the book. show less

Questo libro, curato da Pauli poco prima della morte, raccoglie un insieme di saggi che ben testimoniano la consapevolezza, che egli sempre ebbe vivissima, del significato più generale di ogni ricerca scientifica, valida non solo per il risultato singolo ma per il contributo più ampio al sapere. I saggi, percorsi dal tema comune del valore e dei limiti della conoscenza umana, possono essere distinti in due categorie: la prima puntualizza i personali apporti dell'autore e di altri grandi show more fisici alla scienza contemporanea; la seconda è dedicata a riflessioni sul potere del pensiero e alla validità di alcuni concetti fondamentali della teoria dell'evoluzione biologica e della psicologia dell'inconscio. Lo stile asciutto e rigoroso è animato dal ricordo personale di uomini ed episodi che fanno oggi parte della leggenda della fisica e, più in generale, della conoscenza umana. show less
