| Quotations for Today | |
| "No despot ever flung forth his legions to die in foreign conquest, no privilege-ruled nation ever erupted across its borders, to lock in death embrace with another, but behind them loomed the driving power of a population too large for its boundaries and its natural resources." - Margaret Sanger, American birth-control champion (born 14 Sep 1879) "One can truly say that the irresistible progress of natural science since the time of Galileo has made its first halt before the study of the higher parts of the brain, the organ of the most complicated relations of the animal to the external world. And it seems, not without reason, that now is the really critical moment for natural sciences; for the brain, in its highest complexity - the human brain - which created and creates natural science, itself becomes the object of this science." - Ivan Pavlov (born 14 Sep 1849) "I shall collect plants and fossils, and with the best of instruments make astronomic observations. Yet this is not the main purpose of my journey. I shall endeavour to find out how nature's forces act upon one another, and in what manner the geographic environment exerts its influence on animals and plants. In short, I must find out about the harmony in nature." - Alexander von Humboldt (born 14 Sep 1769) | |

| Ferid Murat, born 14 Sep 1936, was a co-winner of the 1998 Nobel Prize for Physiology or Medicine for discovering that a gas acts as a signalling molecule in the cardiovascular system. This was an entirely new mechanism for how blood vessels in the body relax and widen. What was this gas? | |
| Robert S. Dietz, born 14 Sep 1914, was an American geophysicist and oceanographer who presented a theory of seafloor spreading in which new crustal material continually upwells from the Earth's depths along the mid-ocean ridges and spreads outward. How much new seafloor is made each year by this spreading? | |
| A Russian physiologist, born 14 Sep 1849 was known chiefly for his development of the concept of the conditioned reflex. In a now-classic experiment, he trained a hungry dog to salivate at the sound of a bell, which was previously associated with the sight of food. He received the 1904 Nobel Prize in Physiology or Medicine. Can you name this man? | |

| A French engineer (1839-1882) invented the precursor of the dry cell now providing electrical power for such uses as portable radios.
