Gaussian (software)

Gaussian is a computer program for computational chemistry initially released in 1970 by John Pople and his research group at Carnegie-Mellon University as Gaussian 70. It has been continuously updated since then. The name originates from Pople's use of Gaussian orbitals to speed up calculations compared to those using Slater-type orbitals, a choice made to improve performance on the limited computing capacities of then-current computer hardware for Hartree–Fock calculations. The current version of the program is Gaussian 09. Originally available through the Quantum Chemistry Program Exchange, it was later licensed out of Carnegie Mellon University, and since 1987 has been developed and licensed by Gaussian, Inc.

Gaussian quickly became a popular and widely used electronic structure program. Prof. Pople and his students and post-docs were among those who pushed the development of the package, including cutting-edge research in quantum chemistry and other fields.

Usage examples of "gaussian".

But if the particle experienced an attractive force analogous to the tug of a spring in classical physics, there was a certain shape--a certain Gaussian, like the bell curve of statistics--which was stable.

The right Gaussian, though, in the right environment, was the perfect compromise between uncertainty in position and momentum, allowing the shape of the wave to remain unchanged as it moved.

Frobisher and Benyon had their doubles in these alternate hells and only a narrow-variance Gaussian distribution of experimental success rates had given us our lead over our neighbors.

It showed a lopsided Gaussian distribution, the smooth mountain of the bell curve rising rapidly and then falling back to zero.

We are plunging nearer the Eater now, and a standard Gaussian distribution for the density of small, meteor-sized debris would predict that we shall receive strikes at an exponentiating rate.

If you look down from your bedroom window you can see the spidery Gaussian architecture of Fantasyland, a hyperevolved Crystal Palace where the latest technological artifacts are made available to an increasingly jaded and unsettled public.

Their service is no more than a Jack-and-the-bean-curve, a wide-load Gaussian with Infancy on one end and Adolescence on the other, with a class of cases fat in the mode-peaked middle for which English has no good word.

The terms were so general, they were collections of so many traits, that they said very little in any useful diagnostic sense, especially since both were Gaussian curves in the actual population.

Drukker uses it in his book for determining the Gaussian curvature of spherical and homaloidal space.

There were paper chains hanging in hyperbolic catenary curves and sinusoids, Gaussian distribution bells, and pendulums wreathed in logarithmic spirals.
