Mathematics is the study of quantity, space, structure, and change. Mathematicians seek out patterns and formulate new conjectures. Mathematicians resolve the truth or falsity of conjectures by mathematical proofs, which are arguments sufficient to convince other mathematicians of their validity...

. He later served as director of the UCSB Computer Center and professor in the College of Engineering and extended his revolutionary view of the role of computers to include their use in the classroom. He left UCSB to work in industry and establish his own company, called Culler-Harrison, in 1969. Culler-Harrison became CHI Systems, and later, Culler Scientific.

Work

Culler was the developer of the Culler-Fried Online System, one of the first interactive computer systems in the mid-1960 era. This was the first system to make use of a storage oscilloscope
Oscilloscope
An oscilloscope is a type of electronic test instrument that allows observation of constantly varying signal voltages, usually as a two-dimensional graph of one or more electrical potential differences using the vertical or 'Y' axis, plotted as a function of time,...

 as a means of presenting graphical information, and provided an innovative means of presentation and teaching of mathematical concepts. One of the first object oriented approaches to computing, the system provided a set of operators (e.g., add, subtract, display, multiply, sin, exp) on a predefined set of mathematical objects: scalars, vectors, arrays, and matrices (2-D only, up to about order 30..33).

This interpreted programming language was named MOLSF for Mathematically-Oriented Language, Single-Precision, Floating-point. The MOLSF keyboard consisted of a modified double QWERTY keyboard with the second, upper keyboard, renaming all keys to various functions (special hardware which included APL keyboard capability, two generations existed). The graphical integration was nearly seamless, but memorization of commands was nearly impossible.

The CFS has a second programming language named COL for Card-Oriented Language, somewhat like modern day text-editors. MOLSF and COL didn't communicate very well. They were vastly different languages. The Culler-Fried System only ran at UCSB and TRW
