When asked by one of our students about the significance of Nicolaus Copernicus (1473-1543) and his revolutionary (pun intended) theory of the solar system, most of us would recite the folkloric tale. A brilliant astronomer, dissatisfied with the inaccuracies of Ptolemy, devised a completely new model for the solar system.
There is supposedly a Chinese curse, "May he live in interesting times". While the origin of this phrase is apparently not really in China, it certainly applies to the life of one of the first modern chemists. Antoine-Laurent de Lavoisier was a French nobleman who lived from 1743 until he was beheaded in 1794.
What were personal qualities of the greatest scientist of the twentieth century that differentiated him from his contemporaries? I have read a lot of books about Albert Einstein, who was one of my childhood heroes (along with the Lone Ranger).
One might expect that an especially memorable chess match would have been a world championship game, or at least a tournament competition. However, one of the most famous matches ever played was an exhibition that had no significance for any competition.
A copy of the Periodic Table of the Chemical Elements hangs in virtually every classroom in which chemistry is taught, and it represents one of the great accomplishments of science. I can think of no other such concise and profound consolidation of scientific knowledge.
1.618033989... is a magic number.
I am old enough to remember the 1954 hearings in the matter of J. Robert Oppenheimer, but I was too young to understand that there was more to this story about a supposed Communist in the nuclear weapons program than was being reported in the Los Angeles newspapers of the time.
Haber's name is found in the indices of a large fraction of all books about chemistry. Introductory students learn about the Haber process, by which we (still) synthesize ammonia from nitrogen in the air. Physical chemistry always includes the Haber cycle, a systematic approach to thermochemistry.
Choose ten exemplary chemistry experiments. The synthesis of nylon? Bakelite, the first man-made polymer? The structure of DNA? The fixing of nitrogen? The discovery of buckyballs? Sorry, but none of those made the list of veteran science writer Philip Ball. Mr. Ball was looking for something other than mere importance.
Gurstelle also wrote "Building Bots: Designing and Building Warrior Robots", but I haven't read that one. "Catapult" is definitely in the spirit of "build it yourself", that I like to encourage here and also in "The Cost-Effective Teacher" feature in the print Journal.
