 Plato - Hutchinson encyclopedia article about Plato
Plato's philosophy rejects scientific rationalism (establishing facts through experiment) in favour of arguments, because mind, not matter, is fundamental, and material objects are merely imperfect copies of abstract and eternal ‘ideas’.
Born of a noble family, Plato entered politics on the aristocratic side, and in philosophy became a follower of Socrates.
Moreover, the Earth, which lay at the exact centre of the cosmos, was a sphere and was surrounded by a band of crystalline spheres which held in place the Sun, the Moon, and the planets.

PLATO ran for many years at the U of I, but William Norris's plans to make it a major force in the computing world and a keystone of corporate social responsibility failed.
PLATO I, II and III had been funded by small grants from a combined Army-Navy-Air Force funding pool, but by the time PLATO III was in operation everyone involved was convinced it was worthwhile to scale up the project.

 computational chemistry - Article and Reference from OnPedia.com
In theoretical chemistry chemists and physicists together develop algorithms and computer programs to allow precise predictions of atomic and molecular properties and/or reaction paths for chemical reactions.
There is some dispute within the field on whether the latter methods are sufficient to accurately describe complex chemical reactions, such as those in biochemistry.
A number of software packages that are self-sufficient and include many quantum-chemical methods are available.

 Science Fair Projects - PLATO (Package for Linear Combination of Atomic Orbitals)
PLATO, which stands for Package for Linear combination of ATomic Orbitals, is a suite of programs designed and written by Andrew Horsfield and Steven Kenny.
The program was specifically developed for application to systems with periodic boundary conditions (crystals), however it is also possible to treat isolated molecules.
PLATO was written with speed of calculation as a priority, and uses numerical basis sets and tables of pre-computed one- and two-centered overlap integrals.

I tried to combine several representations of water: lake, droplets (on the bushs, yet not really visible), clouds, and a wet atmosphere (but no ice, sigh).
By combining water, glucose, methane, salts, heat and electricity, far more complex molecules were created than imaginable from the sole ingredients alone.

 Electrolite: "He was the train we did not catch."
Doesn't matter whether they were engineer's dreams or engineer's nightmares it's a given they inspired a lot of current and future engineers and scientists who have surpassed the Heinleins in that regard.
Given that Heinlein is supposedly one of the better hard-science authors in the realm, and that Heinlein brags about making a several foot long calculation to make sure that an orbital parameter in a story is correct, this is silly.
If everything's left abstract (save for a description of what the device does), the (sane) reader can simply take it for granted that the device does its job and move on from there.
