An English teacher reminds her...
An English teacher reminds her students of the written test in her class tomorrow:
"Now, I don't want anyone to miss this important finals exam! I will not tolerate any excuse whatsoever for your absence--unless of course you had to go to the hospital because of a serious injury, or someone died in your immediate family."
Just after she spoke, a wise ass in the back of the class exclaims: "Well, what if I were to tell you that I didn't show up for the test because I experienced complete and utter sexual exhaustion?"
The students in the class try to suppress their snickers and muffled laughter.
The teacher looks sympathetically towards the young man, smiles slyly and states: "Well, then...you'll have to write with your other hand".

Paul CrutzenBorn 3 Dec 1933. Paul Josef Crutzen is a Dutch chemist who received the 1995 Nobel Prize for Chemistry for demonstrating, in 1970, that chemical compounds of nitrogen oxide accelerate the destruction of stratospheric ozone, which protects the Earth from the Sun's ultraviolet radiation. His work, published in 1970, that showed that the nitrogen oxides NO and NO2 react catalytically with ozone, thus accelerating the rate of ozone breakdown to O2 in the stratosphere. These nitrogen oxides are formed principally by decay of nitrous oxide (N2O) which originates from microbiological transformations in the soil. He shared the prize with chemists Mario Molina and F. Sherwood Rowland, who discovered in 1974 that manufactured chlorofluorocarbon gases also contribute to ozone depletion. |
