My new book: Einstein’s Pathway to the Special Theory of Relativity (2nd Edition)

cover

My new book Einstein’s Pathway to the Special Theory of Relativity (2nd Edition) is coming out in August 2017.

My new book is a comprehensive monograph on Albert Einstein’s Odyssey to Special and General Relativity.

It is the second edition of my first book, Einstein’s Pathway to the Special Theory of Relativity:

Picture1

The book brings together the most recent studies regarding the discovery of Special Relativity between 1895 and 1905 and pertaining to the genesis of General Relativity between 1905 and 1918.

The book encompasses an in-depth historiographical analysis of Einstein’s theory of relativity and Einstein’s own derivations and philosophical perspectives of Einstein’s work.

The first chapter provides a narrative of Einstein’s early life until 1914 without resorting to hagiography.

The second chapter discusses Fin de siècle physics.

The third chapter deals with Einstein’s path to the Special Theory of Relativity and Henri Poincaré’s Dynamics of the Electron.

The fourth chapter focuses on the genesis of the General Theory of Relativity from 1905 until approximately 1922.

The fifth chapter centralizes on Einstein’s methodology and creativity, and on Poincaré’s philosophy.

The final chapter analyzes the sources.

The book is 660 pages long, a comprehensive study of Einstein’s discovery of special and general relativity and of Einstein’s cosmology.

I drew the cover of the book.

Einstein loved sailing and he owned a sailboat, which he called Tümmler (porpoise).

Some of the topics discussed in my first book, Einstein’s Pathway to the Special Theory of Relativity

People ask questions about Einstein’s special theory of relativity: How did Einstein come up with the theory of special relativity? What did he invent? What is the theory of special relativity? How did Einstein discover special relativity? Was Einstein the first to arrive at special relativity? Was Einstein the first to invent E = mc2?

Did Poincaré publish special relativity before Einstein? Was Einstein’s special theory of relativity revolutionary for scientists of his day? How did the scientific community receive Einstein’s theory of special relativity when he published it? What were the initial reaction in the scientific community after Einstein had published his paper on special relativity?

In my book, Einstein’s Pathway to the Special Theory of Relativity, I try to answer these and many other questions.The topics discussed in my book are the following:

I start with Einstein’s childhood and school days.

I then discuss Einstein’s student days at the Zurich Polytechnic. Einstein the rebellious cannot take authority, the patent office, Annus Mirabilis, University of Bern and University of Zurich, Minkowski’s space-time formalism of special relativity.

Additional topics treeated in my book are the following: Fizeau’s water tube experiment, Fresnel’s formula (Fresnel’s dragging coefficient), stellar aberration, and the Michelson and Michelson-Morley Experiments.

Einstein’s road to the special theory of relativity: Einstein first believes in the ether, he imagines the chasing a light beam thought experiment and the magnet and conductor thought experiment. Did Einstein respond to the Michelson and Morley experiment? Emission theory, Fizeau’s water tube experiment and ether drift experiments and Einstein’s path to special relativity; “The Step”.

June 30. Ether is superfluous: Faraday and Einstein

On this day in 1905 Albert Einstein’s paper, “On the Electrodynamics of Moving Bodies,” arrived at the editorial offices of the journal Annalen der Physik. The paper was published three months later, and the theory later became known as special relativity. Physics Today.

On April 15, 1846 Faraday gave a lecture at the Royal Institution. The talk was delivered under the title “Thoughts of Ray Vibrations”.  

Faraday began saying: “I incline to believe that when there are intervening particles of matter (being themselves only centers of force), they take part in carrying on the force through the line, but when there are none, the line proceeds through space… we can at all events affect these lines of force in a manner which may be conceived as partaking of the nature of a shake or lateral vibration…
It may be asked, what lines of force are there in nature which are fitted to convey such an action and supply for the vibrating theory the place of the aether?” The lines of force could be electrical, magnetic or gravitational. “…all I can say is, that I do not perceive in any part of space, whether (to use the common phrase) vacant of filled with matter, anything but forces and the lines in which they are exerted…
The view which I am so bold to put forth considers, therefore, radiation as a high species of vibration in the lines of force which are known to connect particles and also masses of matter together. It endeavours to dismiss the aether, but not the vibrations”.
In addition, Faraday explains that the vibrations that occur on the surface of disturbed water, or the waves of sound in gases or liquids, are “direct or to and fro from the centre of action”, whereas the (radiant) vibrations are “lateral”.
Faraday then explains the problem that is inherent in an ether model. He writes that it seems to him, “that the resultant of two or more lines of force is an apt condition for that action which may be considered as equivalent to a lateral vibration; whereas a uniform medium, like the ether does not appear apt, or more apt than air or water”.

Faraday’s lines of force inspired Maxwell in developing electric and magnetic field theory, but Maxwell did not follow Faraday in rejecting the ether. Maxwell developed mechanical models for the ether.

Michael Faraday

Einstein, apparently not knowing about Faraday’s 1846 rejection of the ether, started his 1905 relativity paper with the problematic asymmetries that were inherent in the electrodynamical explanation of the phenomenon of induction by Faraday. Hence, Einstein started with Faraday.

According to Faraday, when a magnet and a closed electric circuit are in relative motion, an electric current is induced in the electric circuit. This current is actually a result of the relative motion between the magnet and the conductor.
If the conductor is at rest in the ether and the magnet is moved with a given velocity, a certain electric current is induced in the conductor. If the magnet is at rest, and the conductor moves with the same relative velocity, a current of the same magnitude and direction is in the conductor. The ether theory gives a different explanation for the origin of this current in the two cases. In the first case an electric field is supposed to be created in the ether by the motion of the magnet relative to it (Faraday’s induction law). In the second case, no such electric field is supposed to be present since the magnet is at rest in the ether, but the current results from the motion of the conductor through the static magnetic field.

This asymmetry of the explanation is foreign to the phenomenon, because the observable phenomena (the current in the conductor) depend only on the relative motion of the conductor and the magnet.

Parts of Faraday’s talk are also quoted in “Fields of Force: The Development of a World View from Faraday to Einstein”,  By William Berkson, pp. 97-99.

The Kyoto lecture notes – Einstein could have visited and consulted his close friend Michele Besso, whom he thanked at the end of his relativity paper. The Patent Office brought them together – their conversations on the way home. Besso was always eager to discuss the subjects of which he knew a great deal – sociology, medicine, mathematics, physics and philosophy – Einstein initiated him into his discovery

Joseph Sauter – Before any other theoretical consideration, Einstein pointed out the necessity of a new definition of synchronization of two identical clocks distant from one another; to fix these ideas, he told him, “suppose one of the clocks is on a tower at Bern and the other on a tower at Muri (the ancient aristocratic annex of Bern)” – synchronization of clocks by light signals.
