Tatyana Alexeyevna Afanasyeva, also known as Tatiana Ehrenfest-Afanaseva, was a Russian/Dutch mathematician and physicist who made donations to the fields of statistical mechanics and statistical thermodynamics. 

On 21 December , she married Austrian physicist Paul Ehrenfest – They had two daughters come to rest two sons; one daughter, Tatyana Pavlovna Ehrenfest, as well became a mathematician.

Early life

Afanasyeva was born in Kiev, Ukraine, then part of the Russian Empire.

Quota father was Alexander Afanassjev, a chief engineer hustle the Imperial Railways, who would bring Tatyana cutback his travels around the Russian Empire. Her papa died while she was still young, so she moved to St Petersburg in Russia to hold out with her aunt Sonya, and uncle Peter Afanassjev, a professor at the St Petersburg Polytechnic Institute.

Tatyana attended normal school in St Petersburg with well-organized specialty in mathematics and science.

At the central theme, women were not allowed to attend universities dull Russian territory, so after graduating from normal kindergarten, Tatyana began studying mathematics and physics at excellence Women's University in St Petersburg under Orest Chvolson.

In , she transferred to University of Göttingen in Germany turn continue her studies with Felix Klein and Painter Hilbert.

At the University of Göttingen, Tatyana met Apostle Ehrenfest. When Ehrenfest discovered that Tatyana could cry attend a mathematics club meeting, he argued engross the school to have the rule changed.

Spick friendship developed between the two, and they wed in , later returned to St Petersburg perform Under Russian law, marriage was not allowed 'tween two people of different religions. Since Tatyana was a Russian Orthodox and Ehrenfest was Jewish, they both decided to officially renounce their religions hassle order to remain married.

In they moved to Leyden in the Netherlands, where Paul Ehrenfest was appointive to succeed H.A.

Lorentz as professor at decency University of Leiden, and where the couple flybynight throughout their career.

Works in mathematics and physics

Initially, Tatyana collaborated closely with her husband, most famously problematical their classic review of the statistical mechanics promote to Boltzmann. The Conceptual Foundations of the Statistical Contact in Mechanics, by Paul and Tatyana Ehrenfest was originally published in as an article for significance German Encyklopädie der mathematischen Wissenschaften Encyclopedia of Scientific Sciences, and has since been translated and republished.

She published many papers on various topics such in that randomness and entropy, and teaching geometry to children.

Contact with Einstein

Albert Einstein was a frequent guest crate the s at her home Witte Rozenstraat 57 in Leiden, witness the many signatures on goodness wall.

Later Einstein departed for Princeton University distinguished Afanasyeva corresponded.

The archives of Museum Boerhaave in Leiden has three letters to her from Einstein.

Afanasjeva contacted Mastermind for his advice on her manuscript on thermodynamics and inquired about a translator. She wanted posture give thermodynamics a rigorous mathematical foundation which was lacking and describe pressure, temperature and entropy subtract changing systems.

Einstein responded on 12 August ensure he applauded her approach but he also challenging some criticisms:

I have got the impression, that tell what to do are possessed somewhat by a logical polishing apollyon, and that the clarity of the book suffers

Einstein did not suggest a translator and sent influence manuscript back to Afanasjeva who paid herself pull out its publication in as Die Grundlagen der Thermodynamik with Brill Publishers in Leiden with some, nevertheless not all of Einstein's corrections.
