What is "observational"

Usage examples of "observational".

Through its principle of relativity, the special theory of relativity declares a democracy of observational vantage points: the laws of physics appear identical to all observers undergoing constant-velocity motion.

In this sense, gravity enforces the symmetry: it ensures the equal validity of all possible observational points of view, all possible frames of reference.

Once gravity is included in the framework, all possible observational vantage points are on a completely equal footing.

In fact, as noted in Chapter 8, so long as the circular dimensions are large enough that they curve back on themselves only beyond the range of our current observational capacity, a circular shape is consistent with the universe we observe.

And is it a coincidence that the outstanding achievement of Mayan society was its observational astronomy, upon which, through the medium of advanced mathematical calculations, was based a clever, complex, sophisticated and very accurate calendar?

When the ritual of obstructionism to obtain the spectra of the BSOs ensued, Margaret Burbridge, a Briton with over fifty years of observational experience, bypassed the regular channels to make the measurement herself using the relatively small 3-meter reflector telescope on Mount Hamilton outside San Jose in California, and confirmed them to be quasars.

The whole body of experimental and observational evidence in biology tends to show that the characters which the individual inherits from his ancestors remain remarkably constant in all ordinary conditions to which they may be subjected.

With practice, however, especially as you compare the tastes of two or three wines, they become obvious, and the observational skills become quite easy to pick up.

He was sharply observational but generally nonconfrontational -- his material the sort that would label him a junior curmudgeon but not seriously controversial.

Through its principle of relativity, the special theory of relativity declares a democracy of observational vantage points: the laws of physics appear identical to all observers undergoing constant-velocity motion.

And there'll be new technology for new and better observational instruments, detectors for dark matter concentrations, axions, gravity waves, and neutrinos, for instance, that will need to be built, using the new engineering techniques.

If you wanted a man to quantize a nonlinear field, diagonalize a messy Hamiltonian, or dream up a delicate new observational test for theories of kernel creation, you couldn't possibly do better than McAndrew.

On the observational side, by far the most important development has been the measurement of fluctuations in the cosmic microwave background radiation by COBE (the Cosmic Background Explorer satellite) and other collaborations.

Watching Moneo, Leto felt the flow of an observational awareness, a thought process which occurred so rarely but with such vivid amplication when it did occur, that Leto did not stir lest he cause a ripple in the flow.

Our own Watcher elders had struggled long and hard with the problem of how to instill observational discipline without overloading or even breaking their children's natural spirits, and I could only hope Shepherd Adams and his people were treading as lightly.
