If he did claim that there had been no technological progress, then yes, that is an absurd claim. But as Yvan is an avid reader of physics, I suspect that what he claimed was that there had been no fundamental discovery along the line of Maxwell's equations of electromagnetic radiation and so on for the past 40 years. There has been nothing that gives rise to a new **branch of**engineering. There have, for example, been speculations about tachyons, but there is no engineering discipline called "Tachyonics" whereby people can routinely send messages to the past, as in Gregory Benford's novel "Timescape." Such ideas remain fantasy. Fantasists can write about warp drives or matter transporters, but this remains fantasy not physics. [Transporting one elementary particle is "boldly mentioned" in the press, but I would expect serious physicists to put an infinite distance between that and Star Trek.] There has been enormous technological advance, and with nanotechnology and quantium computing there will be lots more. But this is all based on old physics. I am sure that there will be genuine new physics, but maybe it requires substantial engineering structures such as space probes or adaptive imaging telescopes before such discoveries can be made and which can be verified by independently repeatable experiments. -- Sincerely, John de Rivaz: http://John.deRivaz.com for websites including Cryonics Europe, Longevity Report, The Venturists, Porthtowan, Alec Harley Reeves - inventor, Arthur Bowker - potter, Holistics, de Rivaz genealogy, Nomad .. and more Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=20847
