アルベルト・アインシュタインさんのインスタグラム写真 - (アルベルト・アインシュタインInstagram)「From the Albert Einstein Archives: 100 years ago today – on May 14, 1919 – Einstein wrote this letter to his sister, brother-in-law and mother who were living together in Switzerland. He was excited about the upcoming solar eclipse – on May 29, 1919 – which would end up proving the theory of relativity. Einstein wrote: ”With this letter I am sending you an article ... as additional nourishment for Mama’s already fitting motherly pride." Within the article, which Einstein enclosed specifically for his mother, it was written that should Einstein's theory be proven correct, it would be accepted as "the true system of the universe."
