| Quotations for Today | |
| "When something comes along and is really important to your career and important to science, important enough so that lots of other people are working on it, you have got to do it in a short time. You have got to get in there and run experiments quickly and get published. That is the killer instinct. I do not think women have that part of it. Part of it comes from sports. It's like scoring a goal." - Marian Koshland, American immunologist (born 25 Oct 1921) "It might liven the place up to have a game that people could play, and which would convey the message that our scientific endeavours have relevance for society." - William Higinbotham (born 25 Oct 1910) who designed the first video game, Tennis For Two, as entertainment for visitors to the Brookhaven National Laboratory's annual visitor's day. (source) "Unfortunately what is little recognized is that the most worthwhile scientific books are those in which the author clearly indicates what he does not know; for an author most hurts his readers by concealing difficulties." - Évariste Galois, French mathematician (born 25 Oct 1811) | |

| Samuel Heinrich Schwabe, born 25 Oct 1789, was an amateur German astronomer who discovered the length of a sunspot activity cycle. Schwabe had been looking for possible intramercurial planets. From 11 Oct 1825, for 42 years, he observed the Sun virtually every day that the weather allowed. In doing so he accumulated volumes of sunspot drawings. In years, what was the periodicity in the number of sunspots visible on the solar disk that he discovered? | |

| On 25 Oct of a certain year, the first domestic microwave oven was sold by Tappan. (Some years previously Raytheon demonstrated the "Radarange," the world's first commercial microwave oven, which cost between $2,000 and $3,000. They lacked the distribution and marketing infrastructure to promote and sell a domestic appliance.) In what decade did Tappan introduce the domestic model microwave oven? | |
| On 25 Oct 1671, Giovanni Cassini discovered one of Saturn's moons. Seen now as Saturn's third largest moon, it is one of the stranger of the 18 moons of Saturn. Its leading side is dark with a slight reddish color while its trailing side is bright. This difference is so striking that Cassini noted that he could see Iapetus only on one side of Saturn and not on the other. Can you name this moon? | |
