Since the first award in 1901, conferment of the Nobel Prize has engendered criticism [1] and controversy. [2] After his death in 1896, the will of Swedish industrialist Alfred Nobel established that an annual prize be awarded for service to humanity in the fields of physics, chemistry, physiology or medicine, literature, and peace.
To give provisional names to his predicted elements, Dmitri Mendeleev used the prefixes eka- / ˈ iː k ə-/, [note 1] dvi- or dwi-, and tri-, from the Sanskrit names of digits 1, 2, and 3, [3] depending upon whether the predicted element was one, two, or three places down from the known element of the same group in his table.

The medal has been awarded to multiple individuals in the same year: in 1882, for example, it was awarded to Dmitri Mendeleev and Julius Lothar Meyer "for their discovery of the periodic relations of the atomic weights"; [6] in 1883 to Marcellin Berthelot and Julius Thomsen "for their researches in thermo-chemistry"; [6] in 1893 to Jacobus ...

Mendeleev predicted other elements that were yet discovered. He put the 62 known elements into columns and rows but he was not the only scientist to attempt this. Julius Lothar Meyer also worked on his own periodic table. Mendeleev had left blanks in his table where the lanthanides are because he did not know what elements were to go there.
This series came from a determination to understand why, and to explore how their way back from war can be smoothed. Moral injury is a relatively new concept that seems to describe what many feel: a sense that their fundamental understanding of right and wrong has been violated, and the grief, numbness or guilt that often ensues.
