Scissors Experiment to prove whether lightwaves can be Doppler shifted Chapt 8 #126; ATOM TOTALITY
So I need an experiment or experiments to prove whether lightwaves can or cannot be Doppler shifted. I need direct experiments. By direct we can easily prove sound waves can be Doppler shifted for we simply stand near a railroad track for the whistle or horn to sound off. But we cannot attain any sort of speed t... 3 Jun 2010 03:29

on a bounded interval, absolutely continuous => bounded variation
Can anyone give a rigorous proof that the restriction of any absolutely continuous (real valued) function to a bounded interval is of bounded variation? I can't. The two books I have looked in state this is "obvious", but give no proofs. I am trying to construct a proof from basically just the definition of ... 4 Jun 2010 11:27

Least Squares for a = a0+arctan(...)?
I don't see LSQ (linear least squares) as a solution for: a = a0 + arctan((y-y0)/(x-x0)) where a0, x0, and y0 are unknowns,and x,y are a known collection of n points. There seems no way to linearize it as for something like y=e**ax to loge(y) = ax. A sinmple gradient method? ... 3 Jun 2010 12:18

Beginner-ish question
I was playing around on my calculator and I happened to find that apparently (-1) ^ (x / pi) = e ^ (x i). Then I got even more bored and I decided to see what (-e) ^ (x / pi) would look like, and then I got still more bored and decided to find a value a such that a ^ x e ^ (x i) = (-e) ^ (x / pi). That's when I ran... 3 Jun 2010 00:14

Uncountability of the Rationals?
Hi All - Looking at some of Herc's recent threads about Cantor's diagonal proof of the uncountability of the reals, a question occurs to me which I actually don't know how a subscriber to transfinite set theory would answer. I'm curious. In Cantor's list of reals, for every digit added, the list doubles in le... 3 Jul 2010 17:54

Collatz conjecture
Let n be an odd integer. Let m be the largest integer such that 2^m divides 3n+1. Define T(n) = (3n+1)/(2^m). Thus T(1)=1, T(5)=1, T(27)=41, T(17)=13 etc. The Collatz conjecture is equivalent to: for any odd integer n, T^k (n)=1 for some positive integer k. Does anyone have a counterexample to the following... 9 Jun 2010 19:50
