| Quotations for Today | |
| "The Earth is the cradle of humanity, but mankind cannot stay in the cradle forever." - Konstantin Tsiolkovsky, Russian pioneer space theorist (born 17 Sep 1857) "In those days, smoking was a no-no, because if you connected up these big machines in the wrong way, something would smoke, and that spelled bad trouble and lots of money. They always adjured us not to smoke, and very few of us actually did... and that was so you'd have maximum sensitivity to any bad smells!" - Oswald Garrison "Mike" Villard Jr., American electronics engineer (born 17 Sep 1916) "..if we reflect upon the discoveries that have been made in animal oeconomy*, we shall find that the most considerable and rational accounts of it have been chiefly owing to the statical** examination of their fluids, viz., by enquiring what quantity of fluids, and solids dissolved into the fluids, the animal daily takes in... And with what force and different rapidities those fluids are carried about their proper channels." (1727) - Stephen Hales, English botanist, physiologist (born 17 Sep 1677) | |
