Evaluating Extraordinary Claims
To demonstrate the problem, I did a simulation where I generated 480 random numbers per subject, representing the 480 time slices in the experiment. I repeated this generation of random numbers 20 times. I compared the send and no-send intervals of random numbers using a T-test; none of the 20 trials found a…

Project GREAT: General Relativity Einstein/Essen Anniversary Test
In September 2005 the kids and I took several very accurate cesium atomic clocks from home and parked 5400 feet up Mt Rainier (the volcano near Seattle) for a full two days.
