||1676: Leeuwenhoek writes to Oldenburg to describe the "little animals" he sees in his microscope. "The 31th of May, I perceived in the same water more of those Animals, as also some that were somewhat bigger. And I imagine, that [ten hundred thousand] of these little Creatures do not equal an ordinary grain of Sand in bigness: And comparing them with a Cheese-mite (which may be seen to move with the naked eye) I make the proportion of one of these small Water-creatures to a Cheese-mite, to be like that of a Bee to a Horse: For, the circumference of one of these little Animals in water, is not so big as the thickness of a hair in a Cheese-mite."

In this paper, he revisits the idea that has come to be called Euler's Phi function. He first introduced the idea to the Academy on Oct 15,1759 but did not include a symbol or name. Euler defined the function as "the multitude of numbers less than D, and which have no common divisor with it."

||1855: Joshua C. Stoddard of Worcester, Massachusetts, received a patent for his calliope. The first instrument consisted of 15 whistles, of graduated sizes, attached in a row to the top of a small steam boiler. A long cylinder with pins of different shapes driven into it ran the length of the boiler. The pins were so arranged that when the cylinder revolved, they pressed the valves and blew the whistles in proper sequence. The different shapes enabled the operator to play notes of varying length. Later, Stoddard replaced the cylinder with a keyboard. Wires running from the keys to the valves enabled the operator to play the instrument like a piano. He patented a successful hay rake in 1879 and a fire escape in 1884. He died on April 4, 1902. Pic search.

His major research activities include; the intrinsic theory of plates and shells, the analysis of large deflection of thin plates and shells, the analysis of corrugated pipes, mechanics of armour penetration, singular perturbation methods, variational principles and generalized variational principles, finite element methods as well as the measurements of atmospheric electricity, spectral analysis of rare-earth elements, wave guide theory, lubrication theory, the development of high-energy batteries, his macro-coding of Chinese characters, etc. The joint work with J.
