NASA's Got the Time If the old cesium and rubidium clocks were not accurate enough for you, contact NASA's Jet Propulsion Laboratory. Their newest design is a low-friction model. It seems previous containers of the ionized atoms used to gauge the passage of time would rob energy from the atomic system, thereby introducing errors. The new device uses an ion trapping field, which holds a wad of ionized mercury atoms in a near frictionless volume for a more perfect count. You can set your watch by this one; it is accurate to within one minute every 10 billion years. A huge collection of my 'Factoids' can be accessed from my 'Kirt's Cogitations' table of contents. Tech Topics Smorgasbord, another manifestation of Factoids, are be found on these pages: | 1

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 ... 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
