Einstein's Zurich Notebook
The Zurich notebook, held by the Albert Einstein Archives at the Hebrew University of Jerusalem, represents an almost complete testimony of Einstein's thinking in an intermediate phase of the emergence of General Relativity, beginning in mid-1912 and ending in early 1913.
In the center of his thinking as it is documented by the notebook was the problem of combining the available physical knowledge on gravitation with a generalization of the mathematical formalism of Minkowski's four-dimensional spacetime, with the aim to create a relativistic theory of gravitation which makes sense from a physical point of view and which corresponds, at the same time, to a consistent mathematical framework.
The principal challenge which Einstein faced consisted in constructing a field equation which, on the one hand, satisfies the requirements resulting from his ambitious program of formulating a theory of gravitation generalizing the principle of relativity, and which, on the other hand, can be reduced by an appropriate specialization to the familiar Newtonian law of gravitation. The history of Einstein's search for such an equation can, on the background of the Zurich notebook, essentially be written as that of a mutual adaptation between mathematical formalism and physical meaning.
This notebook, handwritten by Einstein and found after his death, has been put online for anyone to read.

So cool looking into the thoughts of a great mind conceiving a groundbreaking new theory.
ReplyDeleteI don't think I have ever desired to hold in my hands the works of another so much as this...
ReplyDeleteWow! Who would have thought that one day, we could personally flip through Einstein's hand written notes?
ReplyDeleteAnother complimentary gem is Feynman's Lectures. Searchable, browsable and packed with Feynman's elegant prose style.

Very cool thanks for sharing Corina Marinescu . Just glanced through it, and P.5 and P.7 strike me as odd because it is clearly a Gaussian or Bell Curve Einstein drew - which seems applicable only to Brownian motion and not at all applicable to relativity ... are we sure of that ?

Thank you for sharing , this is really elegant. I really need to do my homework to catch up here ..
But meanwhile I will thrash about with these questions please
-- Why/is a single particle at a quantifiable quantum state ,
-- while multiple particles interacting are essentially along the spectrum of a Plank/Gaussian/Bell curve distribution for any metric we take, is that due to all the Heisenberg uncertainties accumulating ?
If multiple particles interaction becomes a probabilistic Plank/Gaussian/Bell curve distribution, do you see the same statistical curve for 2 interacting particles as you do for a trillion interacting particles ?
-- Is there a non-zero probability for any group of particle(s) with great enough eV-density to fall within its own Schwarzschild radius ?

And here is an approach to answer the above questions :
Statistical mechanics is a branch of theoretical physics and chemistry (and mathematical physics) that studies, using probability theory, the average behaviour of a mechanical system where the state of the system is uncertain
… In physics there are two types of mechanics usually examined:
Classical mechanics and Quantum mechanics. For both types of mechanics, the standard mathematical approach is to consider two ingredients: ..
