Dancing Duck
A circus owner walked into a bar to see everyone crowded about a table watching a little show. On the table was an upside down pot and a duck tap dancing on it. The circus owner was so impressed that he offered to buy the duck from its owner. After some wheeling and dealing, they settled for $10,000 for the duck and the pot.
Three days later the circus owner runs back to the bar in anger, "Your duck is a ripoff! I put him on the pot before a whole audience, and he didn't dance a single step!"
"So?" asked the ducks former owner, "did you remember to light the candle under the pot?"

Georg von HevesyBorn 1 Aug 1885; died 5 Jul 1966 at age 80.Hungarian-Danish-Swedish chemist who was awarded the 1943 Nobel Prize for developing isotopic tracer techniques which enabled understanding of the chemical paths of life processes. For example, a radioactive isotope of phosphorus, prepared in solutions of sodium phosphate can be injected into animals and humans, and blood samples analysed. This show that the radio-phosphorus content in human blood falls after only 2 hours to just 2% of its original amount as it changes places with the phosphorus atoms within the tissues, organs and skeleton. He also discovered, with Dirk Coster, the element hafnium (1923). He published Adventures in Radioisotope Research in two volumes (1962).[EB and a NYT obituary give date of death 5 Jul 1966. DSB gives 6 Jul 1966.] |
