Only started with Perl4 and Perl5 in 1995. I was doing AWK etc for 12 years before that, and resisted switching. I've been doing OO since before C++ hit bigtime, with Objective-C and SmallTalk, so I really like the (no longer new) Perl5 OO style; and the Lispish Map style is also an old friend. What do I hack with Perl? All data that passes my way; systems monitoring scripts at $DayJob, weather data at night, and I cheat on NPR word puzzles. Member: [] [] /. LinkedIn []

N1VUX is my FCC-issued ham radio callsign.

Science News in the New Yorker? Godel's Solution

[ #23527 ]
The current New Yorker has a column exploring the Einstein-Gödel relationship which is both amusing biographica and exposes some little-seen cosmological work by Gödel. Gödel found a third solution to Einstein's equations, one in which the centrifugal virtual force of a rotating universe counteracts gravity. Rereading, it appears Gödel's solution is for a stable universe, not expanding, so I'm not sure if it matches current observations. It might allow for a big-bang and expansion slowing to stability, but I don't see it allowing for *acceleration*, which the string-theory gravitational potential energy leaking into the minute dimensions does. But it may be a component of a fuller explanation w/o epicyclical dark matter or cosmological "constants" (variables).

Most amateur scientists know Gödel and his (in)famous Incompleteness Theorem from Douglas R. Hofstadter's Godel, Escher, Bach: An Eternal Golden Braid, one of the magnum opuses of popular math. A more technical introduction is From Frege to Gödel , which I got as "assigned reading" by a client once. It is a "primary sourcebook" . The editor was perhaps more competent as a mathematical logician than as a bodyguard -- he was Trotsky's amanuensis. Van Heijenoort collected in this sadly O/P edition key seminal papers in mathematical logic, to which he added excellent introductions and segues.
