New Pick-Up Line: What's Your Erdö s Number?

Every man has his price, in this case especially after he has assumed room temperature. Paul Erdö s, a Hungarian mathematician who left this Earth in 1996, was a prodigy in his day. A notable eccentric, he usually had no permanent address and worked with other mathematicians all over the world to author or co-author more than 500 scholarly papers. To have one's name associated with Erdö s on a publication was, and still is, a coveted status symbol in the world of number crunchers. Similar to the six degrees of separation from Kevin Bacon theorem, aspiring mathematicians strive for an "Erdö s Number," which is the separation from actually having co-authored a paper with Erdö s himself: an Erdos Number of 1. Co-authoring a paper with someone who co-authored a paper with Erdö s earns one an Erdö s Number of 2, and so on. So valuable is the ranking that some high-Erdö s-Number authors are auctioning off their co-authorship for a stiff price, just to help raise another mathematician's Erdö s Number. Seems Capitalism has invaded the halls of Academe.

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...
