Feature for Today
Thumbnail of Stephen McCormick

There are two McCormicks who made significant contributions to improving the methods of agriculture. On 26 Aug 1784, Stephen McCormick was born, the American inventor and manufacturer of a cast iron plow with detachable components. He introduced the concept of replaceable and standardized parts. He was the cousin of Cyrus McCormick who invented the famous reaper.

For a quick biography, read this article on Stephen McCormick, and cast your mind back to the conditions of farming, and the difficulty of taming arable land at the beginning of the nineteenth century. When plows attempted to turn over the sod, the ground fought back and damaged the plows. By the time McCormick got involved with addressing the problem, the wooden plows of earlier times had been replaced by cast iron. But there was still a problem to be solved regarding maintenace.

Making parts replaceable through standardization — that was McCormick's important innovation. Eventually thousands of his horsedrawn plows were being manufactured.


Book of the Day
Lavoisier: Chemist, Biologist, Economist (Chemical Sciences in Society)

Antoine Lavoisier, born 26 Aug 1743 is a giant in the history of chemistry. He revolutionized the field and created the first modern table of chemical elements. Yet despite his remarkable importance to modern chemistry, Lavoisier's scientific work was more a hobby than a profession! In fact, because he made his living during the day, his scientific work was relegated to early morning and after-dinner hours! If that was not your perception of such a productive scientist, you may want to read a biography of this remarkable man. Today's book pick is: Lavoisier: Chemist, Biologist, Economist (Chemical Sciences in Society), by Jean-Pierre Poirier who filled the need to write a complete biography of Lavoisier, with the goal of establishing the links between the multidisciplinary activities of his brilliant mind and grasping the logic of his life and death. The author understands chemistry as a research and development director in the R&D in the pharmaceutical industry. He he is a member of the Comite Lavoisier at the Paris Academy of Sciences.

Quotations for Today
Thumbnail of William James
The self-same atoms which, chaotically dispersed, made the nebula, now, jammed and temporarily caught in peculiar positions, form our brains; and the “evolution” of brains, if understood, would be simply the account of how the atoms came to be so caught and jammed.
— William James, American psychologist and philosopher (died 26 Aug 1910). quote icon
Thumbnail of Antoine-Laurent Lavoisier
The impossibility of separating the nomenclature of a science from the science itself, is owing to this, that every branch of physical science must consist of three things; the series of facts which are the objects of the science, the ideas which represent these facts, and the words by which these ideas are expressed. Like three impressions of the same seal, the word ought to produce the idea, and the idea to be a picture of the fact.
— Antoine-Laurent Lavoisier, French chemist (born 26 Aug 1743). quote icon

Tiny ferryboats they were, each laden with its little electric charge, unloading their etheric cargo at the opposite electrode and retracing their journeyings, or caught by a cohesive force, building up little bridges, or trees with quaint and beautiful patterns.
Describing the flow of electrons between electrodes in a vacuum tube.
— Lee De Forest, American inventor (born 26 Aug 1873). quote icon

On 26 Aug 1743, Antoine-Laurent Lavoisier was born a French scientist who is known as the “father of modern chemistry.” In 1778, he found that air consists of a mixture of two gases which he called oxygen and nitrogen.
