Wei Dai,

Good! I will try to access the paper almost immediately. I have long
been partial to FTL as a conjecture. When Professor Nimtz of U.
Koln/Cologne came up with his results, or shortly thereafter, and
interpreted them favorably toward FTL, I emailed him, and he was kind enough
to send me copies of some of his papers by regular (*snail*) mail/post.

Some of the non-Analysis school have indicated here and on other forums that
the pendulum has swung too far away from algebra/arithmetic/number theory,
but the loop theorists like Smolin and Ashtekar and a number of people in
string/brane/duality theories who follow their leads, not to neglect the
MacLane/Lawvere Category theorists in mathematics and physics, actually
constitute an extremely large Mainstream today rather than a downtrodden
minority (although the Gauge Field Theorists still claim the *largest
Mainstream* title). My tendency is to follow the least popular path in
science and in several other fields. That was the way of life of Socrates,
and also of many of the greatest Creative Geniuses in history - including
Kurt Godel, who is still being berated by conformists shuddering at the
thought that there might be limitations as to what assumptions can lead to.
