May 20, 2011 · Einstein’s Blackboard. In the basement gallery of The Museum of the History of Science, there is a relic of the most unlikely kind. It is not a fragment of Saintly bone or a cloth supposedly touched by a religious figure, but rather a humble blackboard, now framed, elevated, and transformed into an artefact for our delectation. Preserved by a savvy Oxonian after Albert …
Jul 23, 2020 · Einstein’s Blackboard was used in a lecture in Oxford on the 16th of May 1931. At that time, his theories of relativity were being combined with astronomical data to explain the shifts towards the red in the spectra of distant galaxies, which indicated that the universe was expanding. In his lecture Einstein outlined a fairly simple model to ...

By keeping Einstein's writings on it for ever, the blackboard became something else and can only regain to its original purpose by being wiped. A second blackboard used by Einstein during the lecture was also donated to the museum, but was accidentally wiped clean by a museum cleaner.
The subject of Professor Einstein's lecture was the theory of "Relativity." It was perhaps as a tribute to the intellectual independence of Manchester that Professor Einstein assumed, to all appearance, that the audience he was facing had its doubts about Relativity.
Abstract. Albert Einstein made three visits to Oxford between 1931 and 1933, staying for a month in the spring of each year. For our understanding of Einstein's work, the Rhodes Memorial Lectures that he delivered during his first visit are of special interest.May 9, 2018
Answer: After six months alone in Munich, Albert concluded that he must get away from there. He thought it absurd to go on like that. He realised that he had been wasting his father's money and everyone's time.Sep 27, 2019

of the law of the photoelectric effectThe Nobel Prize in Physics 1921 was awarded to Albert Einstein "for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect." Albert Einstein received his Nobel Prize one year later, in 1922.

11 July 1923Albert Einstein delivering his Nobel Lecture to the Nordic Assembly of Naturalists in Gothenburg, Sweden, 11 July 1923. Einstein was awarded the 1921 #NobelPrize in Physics for his many contributions to theoretical physics, and especially for his discovery of the law of the photoelectric effect.
Albert Einstein, (born March 14, 1879, Ulm, Württemberg, Germany—died April 18, 1955, Princeton, New Jersey, U.S.), German-born physicist who developed the special and general theories of relativity and won the Nobel Prize for Physics in 1921 for his explanation of the photoelectric effect.
Einstein's Blackboard. Einstein's Blackboard at the Museum of the History of Science in Oxford. Einstein's Blackboard is a blackboard which physicist Albert Einstein (1879–1955) used on 16 May 1931 during his lectures while visiting the University of Oxford in England. The blackboard is in the collection of the Museum of the History ...
The paper, known as the Friedmann–Einstein universe, is of historic significance because it constituted the first scientific publication in which Einstein embraced the possibility of a cosmos of time-varying radius. In the paper, Einstein adopts Alexander Friedman's 1922 analysis of relativistic models of a universe of time-varying radius and positive curvature, but sets the cosmological constant to zero, declaring it redundant, predicting a universe that expands and contracts over time. (The work is sometimes known as the Friedmann–Einstein model of the universe ). With the use of Edwin Hubble's observations of a linear redshift/distance relation for the spiral nebulae, Einstein extracts from his model estimates of ρ ~ 10 −26 g/cm 3, P ~ 10 8 light-years and t ~ 10 10 years for the density of matter, the radius of the cosmos and the timespan of the cosmic expansion respectively. These values are displayed in the last three lines on the Oxford blackboard (although the units of measurement are not specifically stated for the density estimate, cgs units are implied by the other calculations).
Einstein's first lecture was on relativity, the second on cosmology, and the third on unified field theory. All the lectures were delivered in German. A brief report of the second lecture was given in The Times and in Nature.
It has also been noted that the numerical estimates of cosmic parameters in Einstein's 1931 paper – and on the blackboard – contain a systematic error. Analysis of the 1931 paper shows that, given the contemporaneous Hubble constant of 500 km s Mpc , Einstein's estimates of cosmic density, radius and timespan should have been ρ ~ 10 g/cm , P ~ 10 light-years and t ~ 10 years respectively. One line on the blackboard, not included in the published paper, makes the na…
The lecture in which the blackboard was used was the second of three, delivered at Rhodes House in South Parks Road. Einstein's visit to give the Rhodes Lectures, and also to receive an honorary Doctor of Science degree from Oxford University on 23 May 1931, was hosted by the physicist Frederick Lindemann. Einstein's first lecture was on relativity, the second on cosmology, and the third on unified field theory. All the lectures were delivered in German. A brief report of the secon…
In 2013, it was pointed out that the equations on the Oxford blackboard had been taken directly from a key paper on relativistic cosmology written by Einstein in April 1931 and published in the Proceedings of the Royal Prussian Academy of Science on 9 May that year. The paper, known as the Friedmann–Einstein universe, is of historic significance because it constituted the first scientific publication in which Einstein embraced the possibility of a cosmos of time-varying radi…
A blackboard used by Einstein in a public lecture at the University of Nottingham on 6 June 1930 was also preserved after the lecture and is now in the university's archives.
