Work
He performed a long series of very sensitive gravity shielding experiments from 1918 to 1922, which have never been reproduced. Majorana's experiments determined that mercury or lead around a suspended lead sphere acted as a screen and slightly decreased the Earth's gravitational pull. No attempts have been made to reproduce his results using the same experimental techniques. Other researchers have concluded from other data that if gravitational absorption does exist it must be at least five orders of magnitude smaller than Majorana's experiments suggest.
Critical of Albert Einstein's relativity theory, he tried to disprove Einstein’s postulate on the constancy of the speed of light, but he failed and therefore his experiments confirmed Einstein's postulate. Majorana also confirmed Isaac Newton’s law of universal gravitation to high precision.
His later work at Bologna was influenced by correspondence with his nephew Ettore Majorana (1906–1938), a great physicist in his own right.

Famous quotes containing the word work:
“When I consider thy heavens, the work of thy fingers, the moon and the stars, which thou hast ordained;
What is man, that thou art mindful of him?”
—Bible: Hebrew Psalm VIII (l. VIII, 3–4)
“The work was like peeling an onion. The outer skin came off with difficulty ... but in no time you’d be down to its innards, tears streaming from your eyes as more and more beautiful reductions became possible.”
—Edward Blishen (b. 1920)
“Women are in bondage; their clothes are a great hindrance to their engaging in any business which will make them pecuniarily independent, and since the soul of womanhood never can be queenly and noble so long as it must beg bread for its body, is it not better, even at the expense of a vast deal of annoyance, that they whose lives deserve respect and are greater than their garments should give an example by which woman may more easily work out her own emancipation?”
—Lucy Stone (1818–1893)
