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 Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

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.
