Checking the Positional Invariance of Planck's Consant Using GPS

gzipped_tar writes "Whether the fundamental constants really stay the same is always a question worth asking. In particular, the constancy of Planck's Constant is something that cannot be simply ignored, owing to its universal importance in linking the quantum and classical pictures of our world. Using publicly available GPS data and terrestrial clocks, researchers form the California State University were able to verify that the value of h indeed stays the same across different positions in the vicinity of our Earth. Their result says the local position invariance of h is satisfied within a limit of 0.007. The paper is published in the journal Physical Review Letters (abstract), and a free-to-read preprint is available on arXiv. In short: by the well-known formula E = h * f, a hypothetical variation on h induces changes in f, the transition frequency that keeps the time in atomic clocks, both on earth and aboard the satellites. When taking account of other time variations, such as general relativistic time dilation, and assuming the invariance of E (atomic transition energy) on physical grounds, we can figure out an upper bound on the variation of h reflected in the measured variation in f."

But have you figured out why your not getting laid yet?

His dick is so small Heisenberg's Uncertainty Principle is a factor. If he moves it he can't find it, and if he finds it he can't move it.

It seems pretty clear they meant Planck's Consonant. Some argued it was "P" but they've now verified that it's an "h".

Four time zones

[tepples]

Time Cube starts to make a bit more sense when you realize that "four simultaneous 24-hour days" is just a long way of saying "four time zones". But GameCube [fateback.com] still makes more sense.
