Really? While I'm sure you had fun, so did I. Reagan hired Milton Friedman from retirement. Friedman advised a serious reduction in taxes. This freed up corporate money for R&D and America was able to capitalize on, if not create the Internet boom, which has changed the way businesses do business to more efficient and several steps closer to a Star Trek utopia. This also freed up consumer money, which is the grease along which business skids slide. Smart people saved gobs and retired early.

I "surfed" the waters that were handed to me and retired at age 45. Reagan's management of our country was the best thing that ever happened to me!

Relativistic equations 101:Anyway, on a personal level, I have pretty much gotten to where I wanted to go in figuring out the “time dilation” equation which never made any sense to me in the way it is usually presented (I only had one upper division course where it was mentioned.. and being a radar guy, I simply didn’t believe it. But we only had three classes on it, with nary a mention of Maxwell’s equations…)

Let beta = v/c, where v = velocity of an observer and c = speed of light

Time dilation: deltaT prime / deltaT = sqrt(1-beta^2)

Length contraction: deltaX / deltaX prime = sqrt(1-beta^2)

Mass increase: m prime / m = sqrt(1-beta^2)

Kinetic energy: K = mc^2 ( 1/sqrt(1-beta^2) - 1)

You're welcome!So an ongoing “thank you”...

Above.I'd be interested in other participants' takes and personal experiences on the subject - what do you guys think?
