Kirt's Cogitations™ #160

RF Cafe University "Factoids," "Kirt's Cogitations," and "Tech Topics Smorgasbord" are all manifestations of my ranting on various subjects relevant (usually) to the overall RF Cafe theme. All may be accessed on these pages:

Now That's Cold!

The coldest spot on Earth is at the Vostok Ice Station in Antartica, where in 1989 the temperature was measured to be -128.6 F (-89.2 C). At that temperature, water would freeze before hitting the ground when poured from table height. To the other extreme, a high temperature of +136 F (57.8 C) was recorded in El Azizia, Libya, in 1922. At an altitude of 50 miles above the two equators, temps of -220 F (-140 C) are common. In the Earth's inner core, temps can reach +13,000 F (7,200 C), which is hotter that the surface of the sun.

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 lady's voice announced "You've Got Mail" when a new message arrived...
