  • The term abelian is an eponymous adjective the mathematicians succeeded in decapitalizing, and did so, I believe, without the help of a dictionary.

  • "Pertaining to Evangelista Torricelli, an Italian physicist and mathematician (1608–47), who, in 1643, discovered the principle on which the barometer is constructed, by means of an experiment called from him the Torricellian experiment. This experiment consisted in filling with mercury a glass tube closed at one end and then inverting it; the open end was then brought under the surface of mercury in a vessel, when the column of mercury in the tube was observed to descend till it stood at a height equal to about 30 inches above the level of the mercury in the vessel, leaving a vacuum at the top, between the upper extremity of the column and that of the tube. This experiment led to the discovery that the column of mercury in the tube is supported by the pressure of the atmosphere acting on the surface of the mercury in the vessel, and that this column is an exact counterbalance to the atmospheric pressure. See barometer." -- from the Cent. Dict. definition for torricellian (with a lower-case T)
