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 have always thought that one man of tolerable abilities may work great changes, and accomplish great affairs among mankind, if he first forms a good plan, and, cutting off all amusements or other employments that would divert his attention, make the execution of that same plan his sole study and business.”
—Benjamin Franklin (1706–1790)
“Not rarely, and this is especially true of wives and mothers, the motive behind assuming a disproportionate share of work and responsibility is completely unselfish. We want to protect, to spare those of whom we are fond. We forget that, regardless of the motive, the results of such action are almost always destructive and unproductive.”
—Hortense Odlum (1892–?)
“Auld Nature swears, the lovely Dears
Her noblest work she classes, O:
Her prentice han’ she try’d on man,
An’ then she made the lasses, O.”
—Robert Burns (1759–1796)
