The teacher of the Earth Science class was lecturing on map reading.
He spent the class explaining about latitude, longitude, degrees, and minutes. Towards the end of class, the teacher asked his students, "Suppose I asked you to meet me for lunch at 23 degrees, 4 minutes north latitude and 45 degrees, 15 minutes east longitude..."
A student's voice broke the confused silence, and volunteered, "I guess you'd be eating alone, sir."
Parkinson's diseaseIn 1952, Parkinson's disease was successfully treated with surgery for the first time. A team led by Irving Cooper in Islip, N.Y. operated on the brain of patient Raymond Walker. Before the general availability of L-dopa in 1968, the treatment of Parkinson's disease stressed surgery. An early procedure of choice was the pedunculotomy, to reduce tremour. While performing this procedure in 1952, he inadvertently interrupted the patient's anterior choroidal artery (AChA) and was forced to ligate the artery and abort the pedunculotomy. When the patient awoke from anesthesia, his tremour and rigidity had disappeared, and his motor and sensory functions were preserved. Cooper then began to ligate the AChA purposely to reduce tremor in patients. |
