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...

Like a Hot Knife Through Butter ...with a New Twist

My son-in-law, Matt, showed me this video demonstrating the incredible thermal conduction property of graphene. A miracle material for seemingly every other realm of physics, thermo-conductive pyrolytic graphite (TCPG) conducts heat with twice the efficiency of diamond, and 6x the efficiency of copper and silver. Because of the extreme thermal conductivity, the heat from the guy's fingers is enough to slowly force the graphene sheet through the ice cube. In the future, the colloquial saying for expressing how easily a material is cut might change from "like a hot knife through butter" to "like a body-temperature graphene sheet through an ice cube."
