He could multiply two, 20-digit numbers in his head in 6 minutes. He could look at a field of sheep for only a couple seconds, then tell the exact count. His powers were attributed to a true photographic memory. Beginning at 16 years old, he was enlisted by famous mathematician Carl Friedrich Gauss to generate the most precise tables of the day for logarithms, hyperbolic and trigonometric functions. These calculations would otherwise take years to make and require an entire staff of mathematicians. Since Johann was paid for his services, this possibly constituted the world's first instance of rented computer time. |

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 typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived... All trademarks, copyrights, patents, and other rights of ownership to images and text used on the RF Cafe website are hereby acknowledged. My Hobby Website: AirplanesAndRockets.com
Please Support RF Cafe by purchasing my ridiculously low−priced products, all of which I created.
