Atomic Clocks and General Relativity - Daniel Kleppner

Source - serious-science...
Can Einstein’s general relativity be used for practical purposes? How accurate are the time measurements with current technologies? Professor of Physics at MIT Daniel Kleppner explains how to measure height using only a clock.

That talk lives up to the Serious Science label!

Does gravity affect the clock or time? Clocks do not measure time, they simply generate a sequence of events that cannot be directly connected to time. The strength of gravity may only be affecting the vibrational rate of atoms.

good point! I found this deep and profound: kzbin.info/www/bejne/rnfEipx4odN_e80

so this is the guy who wrote my problem set...

Hey explains things a lot like Feynman. Pretty cool in my book.

I got here through Thunderf00t talking about creationists, denying the gravation effect on atomic clocks. Sounded neat, very interesting chat! Never thought about it till then. Now I've gotta look up the history of atomic clocks, sounds super cool!

Absolute mad lad. Great, precise, clear explanation!

anyone here hear the tick tick sound on background don't know why they put on the video

So if our alien pals are constantly zipping around in their ships at those extremely fast speeds (as I have witnessed many times) then is it possible theyve been here all along? Since the very begining ? Since humanity has only been civilized for a few thousand years... ? Seems likely. Puts things into perspective if you ask me.

"Gravity curves spacetime" because the mechanism of gravity is a phase-gradient of relative oscillation. We measure the duration of an event with a clock that rotates in situ, like the atoms used for atomic clocks, so different rates have different "curvature" (or inflation rates), from zero to +/- infinity and the rates are quantized phase-states. It's how temporal superposition is projected to become the inflation-condensation interference pattern of spacetime in terms of " rotational" phases of time duration. Theoretically, or permanently hypothetically, ...because the QM process is an evolving state in the observable dimensions, and a superficially-uncertain "topological" fluid, an observable point of connection / continuity, ..observation is a resonant compound of cycles, now. Ie the "perfect" complexity of omnidirectional omnidimensional state of Eternity-now existence. (If it was definable there would be a possibility of a complete description or explanation of eternity, but "what we get" is the interference pattern / identity, of the Space-Time image now) Sufficient "confirmation" of the temporal superposition eternal-hypothesis is that if eternity now were not definitive of the requirements for acceptance of mathematics in continuity, then, even though the image of spacetime constants evolve, the relative states of numerical proportion are eternal "truths" or phases, on an infinite existence axis. And all rotation (as in gyroscopes) see the axis of eternity the singularity, independently as quantized information at a point.
