Those are all names for the art of rock skipping. It is now as much of a science as an art, thanks to physicist Lyderic Bocquet and his young son. Mr. Bocquet formulated equations of motion for stones, modeling them as a thin, flat object bouncing off a uniform surface. He discovered that the stones initial rate of speed and spin rate were the biggest factors in the stone's ability to skip multiple times. A high rate of spin generates a gyroscopic effect that prevents the stone from tumbling and diving into the water. Per his equations, the world record of 38 skips corresponds to a stone flying 12 meters while spinning at a rate of 14 revolutions/second. |

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
