| Quotations for Today | |
| "Realizing how often ingenious speculation in the complex biological world has led nowhere and how often the real advances in biology as well as in chemistry, physics and astronomy have kept within mechanistic interpretation, we geneticists should rejoice, even with our noses on the grindstone (which means both eyes on the objectives), that we have at command an additional means of testing whatever original ideas pop into our heads." - Thomas Hunt Morgan (died 4 Dec 1945) "Their business (those who believe in evolution) is not with the possible, but the actual - not with a world which might be, but with a world that is. This they explore with a courage not unmixed with reverance, and according to methods which, like the quality of a tree, are tested by their fruits. They have but one desire - to know the truth. They have but one fear - to believe a lie." (1870) - John Tyndall, British physicist (died 4 Dec 1893) "I allude to Charles Darwin, the Abraham of scientific men - a searcher as obedient to the command of truth as was the patriarch to the command of God." (1877) - John Tyndall, British physicist (died 4 Dec 1893) | |

| Alfred Day Hershey, born 4 Dec 1908, was an American biologist who was a co-recipient of the Nobel Prize for Physiology or Medicine in 1969. The prize was given for research done on bacteriophages (viruses that infect bacteria). Hershey used an isotope- labeled phage to to infect a bacterial colony and begin to inject their genetic material into the host cells. Then he separated the phage particles from the bacterial walls without rupturing the bacteria. What equipment did he use for this separation? | |

| A British physicist (1820-1893) who demonstrated why the sky is blue also studied diamagnetism, glacier motion, and showed that ozone was an oxygen cluster rather than a hydrogen compound. He also invented the fireman's respirator and made other less well-known inventions including better fog-horns. Can you name this physicist who studied the diffusion of light in the atmosphere? | |
| Luigi Galvani (1737-1798) was an Italian physician and physicist studied the structure of organs and the physiology of tissues who is best known for his investigation of the nature and effects of what he conceived to be electricity in animal tissue. What observation made by Galvani led to this discovery? | |
