In 1960, working with his student Daniel Kleppner, now an emeritus professor of physics at the Massachusetts Institute of Technology, Dr. Ramsey invented a different type of atomic clock, known as the hydrogen maser, whose remarkable stability has since been used to confirm the minute effects of gravity on time as predicted by Einstein's theory of general relativity.
In the 1950s physicists Norman Ramsey and Daniel Kleppner were carrying out research to test Einstein's theory of General Relativity by measuring the effects of gravity on time.
General relativity also predicts novel effects of gravity, such as gravitational waves, gravitational lensing and an effect of gravity on time known as gravitational time dilation.
He has carefully plotted a trajectory to avoid falling into the hole, but has neglected to take into account an important effect of gravity on time: a watch appears to move more slowly inside a strong gravitational field than outside it.
It would have to be relaxed without being totally campy, serious enough to convey the gravity of the time without disguising the fact that for many people it was a good time.
We stare at our screens following the latest from Sevastopol, reaching for a snack that is floating away in the zero gravity of our times.
Albert Einstein's general theory of relativity is our most successful, most sophisticated theory of gravity of all-time.
Wharton dropped its enjoyable role-playing format in order to cram in more serious lectures, reflecting the gravity of the times.
Fascinated by this phenomenon, a San Diego engineer several years ago created a toy that extends the circular rolling to seemingly gravity-defying lengths of time.
All convictions are evaluated on a case-by-case basis, considering the nature and gravity of the conviction, time elapsed since the conviction, and job-relatedness.
