Einstein in Tokyo in 1922
When Albert Einstein was on board of a Japanese ship sailing from Marseille, France, to Kobe, Japan, in November 1922, he received a notice that he was awarded a Nobel Prize.
Therefore, Einstein’s first lecture after he became a Nobel Prize winner was significantly conducted in Japan, probably with the deepest emotion in his life, during his 43-day stay.

When people want to show his smartness or point at foolishness of others, they sometimes use the name “Einstein.” It is a common thing in Japan, Europe, and America with all of which Einstein had some relation.
Everybody knows and can calculate one of Einstein’s equations, e = m*c**2, which led to realization of nuclear bombs, for it shows mass is physically equivalent to energy.
But, as for another Einstein’s equation G = (8*pi*g / c**4)*T, it is extremely difficult to calculate unless you master Riemannian geometry.
Also, note that “pi” appears here, and “c” is the speed of light, and “g” is the gravitational constant.
“G” and “T” request some special efforts in understanding a mathematical method called tensor, a rule to change a system of coordinates against a physical entity. They include thousands of combinations of terms if mathematically extended with partial differential equations as its components.
In addition, as Riemannian geometry is too unique, it is almost impossible for ordinary people to solve the equation.
However, put simply, G = T.
G: Distortion of space
T: Concentration of energy and kinetic momentum
Metaphorically speaking, space and time is dominated by a person who has a strong personality, talents, the will, or love, in any circles, communities, or occasions.
Dr. Hawking solved the equation given a special condition of a black hole, which has made him a hero.

Einstein wrote 30,000 letters and correspondences in his life.
One student in Japan sent to Einstein staying in Tokyo a letter with a certain question on physics; he then received a reply from the very person Einstein. In the return mail, with a letter paper of the Imperial Hotel in Tokyo, the student found only one equation: G = (8*pi*g / c**4)*T.
The student later became a very successful physical scientist in Japan and died in 1982. The letter was recently found by his bereaved family, which was reported last year in a nationwide newspaper.
When you use the name of Einstein in your conversation or joke, you had better remember that Einstein presented one of his best equations even to a nameless student in Tokyo in 1922.
(Why did Einstein accept invitation from Japan? It is because he had read a book written by Lafcadio Hearn (1850-1904), a U.S. reporter who had become a naturalized citizen of Japan.
Hearn, with an adopted Japanese name Yakumo Koizumi, especially loved a city famous in the Japanese myth. There was even a French girl who read Hearn’s book in, probably, Paris and took courage to travel to Japan and visit the city all alone in the time not so different from that of Einstein’s visit. )
