Google Tribute to Nicolaus Copernicus

Google Tribute to Nicolaus Copernicus (February 19, 1473) - RF CafeGoogle's homepage today has an animated tribute to Nicolaus Copernicus on this 540th anniversary of his birthday. Only the planets know to exist in Copernicus's day (out to Jupiter) are shown orbiting the sun, plus our moon is orbiting Earth. Galileo had not yet discovered the large large moons of Jupiter nor had Christiaan Huygens found Saturn's largest moon, Titan. Right-click in an empty place on the screen and select View Source to see the immense amount of code used to generate that animation (turn word wrap on).

About RF Cafe

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
