| Quotations for Today | |
| "It is odd to think that there is a word for something which, strictly speaking, does not exist, namely, 'rest.' We distinguish between living and dead matter; between moving bodies and particles at rest. This is a primitive point of view. What seems dead, a stone or the proverbial 'door-nail', say, is actually forever in motion. We have merely become accustomed to judge by outward appearances; by the deceptive impressions we get through hour senses." - Max Born (born 11 Dec 1882) "If my efforts have led to greater success than usual, this is due, I believe, to the fact that during my wanderings in the field of medicine, I have strayed onto paths where the gold was still lying in the wayside. It takes a little luck to distinguish gold from dross, but that's all." - Robert Koch, German bacteriologist (born 11 Dec 1843) "Prophetic of infidel times, and indicating the unsoundness of our general education, 'The Vestiges of the Natural History of Creation' has started into public favour with a fair chance of poisoning the fountains of science, and sapping the foundations of religion." (Book review 1845) - David Brewster, Scottish physicist (born 11 Dec 1781) | |

| A Canadian-born manufacturer, born 11 Dec 1874, was the inventor of the pasteurizing process for cheese. In 1916, he patented a processed cheese formula, based on milk solids, that would not spoil. He took his formula to the U.S. Army, and sold them 6 million pounds of the processed cheese product. Soldiers developed a taste for the creation. The processed cheese was a popular replacement during the depression for expensive real cheese. Can you name this inventor? | |
| Sir David Brewster, born 11 Dec 1781, was a Scottish physicist noted for his experimental work in optics and polarized light, and especially for Brewster's Law, which relates the refractive index of a material to its polarizing angle. He patented the kaleidoscope in 1817. Later, he used lenses to improve 3D images viewed with a stereoscope. Brewster also recommended a notable use of the lightweight, flat Fresnel lens. What application did he recommend for the Fresnel lens? | |
