General relativity predicts that clocks run more slowly near massive objects. The effect is small—a clock at sea level lags behind one 1000 m above sea level by only 9.4 ns/day. Here, we demonstrate that a measurement of this effect can be done by undergraduate students. Our paper describes an experiment conducted by undergraduate researchers at Colorado College and the United States Air Force Academy to measure gravitational time dilation. The measurement was done by comparing the signals…

Bias in confidence: A critical test for discrete-state models of change detection.
2 studies showing that biased confidence judgments can be reliably observed are reported, a behavioral signature that rejects a large number of discrete-state models and complementary modeling analyses support the notion of a mixture account.


Gravitational Red-Shift in Nuclear Resonance
The several theories of relativity predict the frequency of electromagnetic spectral lines to be proportional to the gravitational potential. Experiments are proposed to observe the timekeeping of a
Accuracy evaluation of the primary frequency standard NIST-7
A comprehensive approach to the evaluation of the uncertainty of a primary frequency standard by indirect, model-dependent means that leads to a lower combined standard uncertainty (CSU) and leaves frequency measurements under altered conditions as a powerful search technique for unknown biases.
Relativity and the Global Positioning System
We need general relativity to understand extreme astrophysical realms. But the theory also turns out to be essential for the many mundane activities that nowadays rely on the precision of the GPS.
