It makes the result sound much\nmore exotic and science-fictiony than it is. They\'ve found a better\nway to do magnetic levitation -- that is, to use magnetic forces to\nbalance the force of gravity.\n\nIf you call applying another force to balance gravity "controlling the\namount of gravity," then my chair is controlling the amount of gravity\non me right now.\n\n>Read the story here: http://www.physorg.com/news4059.html\n>There are a few pictures available:\n>http://www.nottingham.ac.uk/~ppxatc/levitation/Flotation.html\n\n-Ted\n\n--\n[E-mail me at name@domain.edu, as opposed to name@machine.domain.edu.]\n\n</UL></PRE></font></td></tr></table></BODY><HTML>');"> <IMG SRC=/images/buttons/ip.gif BORDER=0 ALIGN=CENTER ALT="View this Usenet post in original ASCII form"> View this Usenet post in original ASCII form </a></div><P></jabberwocky>In article <1116754742.445381.222450@g43g2000cwa.googlegroups.com>,
