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:
“I pray every single second of my life; not on my knees, but with my work. My prayer is to lift woman to equality with man. Work and worship are one with me. I can not imagine a God of the universe made happy by my getting down on my knees and calling him “great.””
—Susan B. Anthony (1820–1906)
“So is the English Parliament provincial. Mere country bumpkins, they betray themselves, when any more important question arises for them to settle, the Irish question, for instance,—the English question why did I not say? Their natures are subdued to what they work in. Their “good breeding” respects only secondary objects.”
—Henry David Thoreau (1817–1862)
“Unless a group of workers know their work is under surveillance, that they are being rated as fairly as human beings, with the fallibility that goes with human judgment, can rate them, and that at least an attempt is made to measure their worth to an organization in relative terms, they are likely to sink back on length of service as the sole reason for retention and promotion.”
—Mary Barnett Gilson (1877–?)
