Ricky Martin
singerBorn: 12/24/1971Birthplace: San Juan, Puerto Rico
Latin singer who burst onto the U.S. music scene after his hip-shaking performance at the 1999 Grammy Awards. At age 12 Martin joined the Latin boy band Menudo. Five years later, when the band had achieved superstardom, he was kicked out for being too old. Graduating from high school and dabbling in acting occupied Martin for the next few years before he released two solo albums (Ricky Martin and Me Amaras) that became hits on the Latin pop charts. In 1994 he landed a regular role on the soap opera General Hospital, which led to a year-long stint on Broadway in Les Miserables. In 1995, Martin released A Medio Vivir, a rock album with Latin stylings. Vuelve (1998) contained the international hit “La Copa de la Vida/The Cup of Life,” which became an anthem for the 1998 World Cup and won Martin a Grammy for Best Latin Pop Performance. He followed it up in 1999 with Ricky Martin, his English-language debut, which included another smash hit “Livin' La Vida Loca,” and received three Grammy nominations. Sound Loaded was released in November 2000.

Louis Pasteur dec 271822–1895, French Chemist
He taught at Dijon, Strasbourg, and Lille, and in Paris at the École normale supérieure and the Sorbonne (1867–89). His early research consisted of chemical studies of the tartrates, in which he discovered (1848) molecular dissymmetry. He then began work on fermentation, which had important results. His experiments with bacteria conclusively disproved (1862) the theory of spontaneous generation and led to the germ theory of infection. His work on wine, vinegar, and beer resulted in the development of the process of pasteurization. Of great economic value also was his solution for the control of silkworm disease, his study of chicken cholera, and his technique of vaccination against anthrax, which was successfully administered against rabies in 1885. In 1888 the Pasteur Institute was founded in Paris, with Pasteur as its director, to continue work on hydrophobia and to provide a teaching and research center on virulent and contagious diseases.
Kepler, Johannes
Kepler, Johannes (yōhä'nus kep'lur) [key], dec 27 1571–1630, German astronomer. From his student days at the Univ. of Tübingen, he was influenced by the Copernican teachings. From 1593 to 1598 he was professor of mathematics at Graz and while there wrote his Mysterium cosmographicum (1596). This work opened the way to friendly intercourse with Galileo and Tycho Brahe, and in 1600 Kepler became Tycho's assistant in his observatory near Prague. On Tycho's death (1601) Kepler succeeded him as court mathematician to Holy Roman Emperor Rudolf II. In 1609 he published the results of Tycho's calculations of the orbit of Mars. In this celebrated work were stated the first two of what became known as Kepler's laws. In 1612, becoming mathematician to the states of Upper Austria, he moved to Linz. He wrote an epitome of the astronomy of Copernicus in 1618, and in 1619 De cometis and Harmonice mundi (in which was announced the third of Kepler's laws). In 1626, Kepler moved to Ulm. After his death his manuscript writings, bought by Catherine II of Russia, were placed in the observatory of Pulkovo.
