Time travel = perpetual motion machine? Time travel = Horn of Plenty?     OR NOT?31 Aug 2008 22:43 GMT15
I was thinking about this. In addition to all the various "obvious"
issues with time travel (namely, causality paradoxes where the trip is
rendered causally impossible) -- there seems to be one other I haven't
heard much discussion of: namely, that it seems that if time travel is
"Spooky" Physicists Up Close!31 Aug 2008 20:21 GMT19
Has anyone noticed that there is not a "belief system" on the planet,
past or present, more bizarre, more slavishly religious in nature than

Backing of a Piezo Transducer31 Aug 2008 13:16 GMT4
Does anybody know why the backing of a piezo-transducer increases its
bandwidth?
I would need the physical principle behind it.

The phase of matter31 Aug 2008 07:25 GMT2
Does matter have phase? If so how does one measure the phase and could
matter have othogonal phase so that more than one type of object
occupies the same space?

"Can the Second Law of Thermodynamics Be Circumvented?"
    The validity of the First and Second Laws of Thermodynamics seems to be
beyond question. Under the first law, the total energy content of a closed
system must remain constant. Under the second law, the availability of ...
