Chemist
A chemist (from Greek ''chēm(ía)'' alchemy; replacing ''chymist'' from Medieval Latin ''alchemist'') is a scientist trained in the study of chemistry. Chemists study the composition of matter and its properties. Chemists carefully describe the properties they study in terms of quantities, with detail on the level of molecules and their component atoms. Chemists carefully measure substance proportions, chemical reaction rates, and other chemical properties. In Commonwealth English, pharmacists are often called chemists. Chemists use their knowledge to learn the composition and properties of unfamiliar substances, as well as to reproduce and synthesize large quantities of useful naturally occurring substances and create new artificial substances and useful processes. Chemists may specialize in any number of subdisciplines of chemistry. Materials scientists and metallurgists share much of the same education and skills with chemists. The work of chemists is often related to t ...

Composer
A composer is a person who writes music. The term is especially used to indicate composers of Western classical music, or those who are composers by occupation. Many composers are, or were, also skilled performers of music. Etymology and Definition The term is descended from Latin, ''compōnō''; literally "one who puts together". The earliest use of the term in a musical context given by the ''Oxford English Dictionary'' is from Thomas Morley's 1597 ''A Plain and Easy Introduction to Practical Music'', where he says "Some wil be good descanters ..and yet wil be but bad composers". 'Composer' is a loose term that generally refers to any person who writes music. More specifically, it is often used to denote people who are composers by occupation, or those who in the tradition of Western classical music. Writers of exclusively or primarily songs may be called composers, but since the 20th century the terms 'songwriter' or ' singer-songwriter' are more often used, particul ...

ILLIAC I
The ILLIAC I (Illinois Automatic Computer), a pioneering computer in the ILLIAC series of computers built in 1952 by the University of Illinois, was the first computer built and owned entirely by a United States educational institution. Computer The project was the brainchild of Ralph Meagher and Abraham H. Taub, who both were associated with Princeton's Institute for Advanced Study before coming to the University of Illinois. The ILLIAC I became operational on September 1, 1952. It was the second of two identical computers, the first of which was ORDVAC, also built at the University of Illinois. These two machines were the first pair of machines to run the same instruction set. ILLIAC I was based on the IAS machine Von Neumann architecture as described by mathematician John von Neumann in his influential '' First Draft of a Report on the EDVAC''. Unlike most computers of its era, the ILLIAC I and ORDVAC computers were twin copies of the same design, with software compatibili ...
