gamma

/ˈɡamə

noun

1The third letter of the Greek alphabet (Γ, γ), transliterated as ‘g’.

The combinations γγ, γκ, and γχ are usually transliterated as ‘ng’, ‘nk’, and ‘nkh’ or ‘nch’.

In the Greek alphabet, each letter has a name that is not directly related to its sound value (alpha, beta, gamma, etc.), but this practice is not common in Roman derived alphabets....

His professional affiliations include Alpha Zeta, Gamma Sigma Delta, Phi Delta Kappa, and Phi Kappa Phi.
She works with the homeless through her participation in Delta Kappa Gamma and is involved with the Make a Wish Foundation.

1.1 [as modifier] Denoting the third in a series of items, categories, etc. the alpha, beta, gamma system of share classification...

Even a seemingly tiny piece of radioisotope like plutonium can be emitting many millions of alpha, beta or gamma particles per week.
All of this suggests that it would be more helpful to redirect theoretical attention to the interplay between alpha (= ‘evenness’), beta, and gamma diversity.
If one demarcates alpha, beta, and gamma world cities as three meaningful tiers, the alpha tier includes the usual urban triumvirate (London, New York, and Tokyo) but also Paris.

1.2British A third-class mark given for an essay or other piece of work.I was very close to a First, but got a gamma double-minus in "Political Institutions".

His first observation was made on 3rd December 1725, and he saw the star - Gamma Draconis - in his telescope as he expected.
In 1725 Bradley systematically observed the star Gamma Draconis and noticed a seasonal shift in the star's position on the sky.
It is also known as the Amazon Star, the warrioress, or Gamma Orionis.

2 [as modifier] Relating to gamma rays: gamma detector...

The nuclear portal monitor and Palm Pilot neutron and gamma detector are designed to detect and identify the illicit movement of nuclear materials.
Three complementary instruments make up GRS: the gamma subsystem, the high-energy neutron detector, and the neutron spectrometer.
By measuring the relative velocity of backscattered gamma particles, they reveal the chemical environment of Fe nuclei in the rock.

3 Physics (plural same) A unit of magnetic field strength equal to 10⁻⁵ oersted.At very small velocities, gamma is approximately equal to one....

Mass m in the equation E = mc is equal to the rest mass times the factor gamma.
It might also find that, within the experiment's limits of precision, gamma is equal to one - just as Einstein predicted.

Origin

Via Latin from Greek.
