Physicists have created atomic clocks so precise that they can measure deformations in spacetime itself, according to new research.

Hi

Certainly a cool clock and yes I’d love to have one in the ….errr … warehouse (as long as somebody else pays
the power bill).

I seem to recall others as actually having measured gravity effects using atomic clocks …. :)

Yes, that’s just the way the article was written and not a knock in any way on the *very* impressive clock.

A little humor:

This situation reminds me of an old saying we had at HP:

How do you insult a clock engineer?

"Hey man, that's a great thermometer you designed!"

The new version of this is now:

"Hey man, that's a great accelerometer you designed". :-)

I wonder if that "insult" was the inspiration for thermometers designed
around quartz resonators.

For more details on the new "accelerometer", one might want to read:

https://www.nature.com/articles/s41586-018-0738-2.epdf?referrer_access_token=xI4XbO8QUPT0oGiggqlnj9RgN0jAjWel9jnR3ZoTv0NOfvtdRGwNwsijc3L-wdrR-gN_XGjZvnhSHG8Z_GRAG2TFlrE0BhLZBwI67_QAp5OjAnEKQ4WJ4wCjk5w4vygIPUQtVEyDSwAATCo0K5MU6LufwkNUiCSha11I0_PKQaLYE9fGZ8PkVdTUdQpyGoiVbb0jP8MraWacVecZgLo2L2CMYUI4WaKOR_F4q5s8PY5IBcxvTydcNh79JRTUvUrd&tracking_referrer=www.theregister.co.uk

This can be read, but apparently not downloaded by just anybody.
