On extending this inquiry to other allotropic crystals, he observed a similar variation, and was thus led, in 1825, to the discovery that allotropic crystals, when heated, expand unequally in the direction of dissimilar axes.

The Nevians decide that humans are inferior beings, and carve up both fleets using a ray that extracts every atom of free or combined iron in both sides'ships and personnel into a red, liquid " allotropic iron ".

It was at that time that it was announced Heisenberg had won the Prize for 1932 " for the creation of quantum mechanics, the application of which has, inter alia, led to the discovery of the allotropic forms of hydrogen ".

Despite opposition from some theological fellows, he was elected to the Aldrichan Chair ( later renamed as the Waynflete Professor of Chemistry ) at Oxford University 1865 to 1872, and is chiefly known for his investigations on the allotropic states of carbon and for his discovery of graphitic acid.

Taking into account this theoretical framework, pure parahydrogen was first synthesized by Paul Harteck and Karl Friedrich Bonhoeffer in 1929 . When Heisenberg was awarded the 1932 Nobel prize in physics for the creation of quantum mechanics, this discovery of the " allotropic forms of hydrogen " was singled out as its most noteworthy application.

It was at that time that it was announced Heisenberg had won the Prize for 1932 " for the creation of quantum mechanics, the application of which has, inter alia, led to the discovery of the allotropic forms of hydrogen " and Erwin Schr�dinger and Paul Adrien Maurice Dirac shared the 1933 Prize " for the discovery of new productive forms of atomic theory ".

In 1928, Einstein nominated Heisenberg, Born, and Jordan for the Nobel Prize in Physics, but Heisenberg alone won the 1932 Prize " for the creation of quantum mechanics, the application of which has led to the discovery of the allotropic forms of hydrogen ", while Schr�dinger and Dirac shared the 1933 Prize " for the discovery of new productive forms of atomic theory ".

Among the metallic elements that occur in nature in significant quantities ( 56 up to U, without Tc and Pm ), almost half ( 27 ) are allotropic at ambient pressure : Li, Be, Na, Ca, Ti, Mn, Fe, Co, Sr, Y, Zr, Sn, La, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Yb, Hf, Tl, Th, Pa and U . Some phase transitions between allotropic forms of technologically relevant metals are those of Ti at 882 �C, Fe at 912 �C and 1394 �C, Co at 422 �C, Zr at 863 �C, Sn at 13 �C and U at 668 �C and 776 �C.
