I've seen the effect you describe explained in an article somewhere, very likely New Scientist or SciAm about five years ago. When you rapidly heat or cool metals, very often changes in crystal lattice structure is involved some of them resulting in quite drastic changes to volume. Heat is essentially atoms wiggling about, and when you change the modes of freedom for the atoms, they may have to wiggle harder. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 p...@freebsd.org | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
