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."
Johann DeisenhoferBorn 30 Sep 1943.German biochemist who received the 1988 Nobel Prize for Chemistry, along with Hartmut Michel and Robert Huber, for the determination of the three-dimensional structure of certain proteins that are essential to photosynthesis. Using X-ray crystallography (1982-85), they unravelled the full details of how a membrane-bound protein is built up, revealing the structure of the molecule atom by atom. The protein was taken from a bacterium which, like green plants and algae, uses light energy from the sun to build organic substances. Photosynthesis in bacteria is simpler than in algae and higher plants, but the work has led to increased understanding of photosynthesis in those organisms as well. |
