Esta semana en la Ciencia: October 7, 1939 Birthday of Harold W. Kroto, English chemist who shared (with Richard E. Smalley and Robert F. Curl, Jr.) the 1996 Nobel Prize for Chemistry for their joint discovery of the carbon molecules with 60 or more carbon atoms arranged in closed shells (fullerenes). October 9, 1879 Birthday of Francisco Flores, scientist who study luminiscence in off-stoichiometry silicon oxides. Birthday of Max von Laue, German physicist who was a recipient of the Nobel Prize for Physics in 1914 for his discovery of the diffraction of X-rays in crystals, which enabled scientists the study the structure of crystals, and marked the origin of solid-state physics and the development of modern electronics. October 10, 1796 According to an unfounded legend, the birthday of the metric system (the 10/10 date seems to signify the base 10); the real birth date might be 8 May 1790, when the French National Assembly decided to create a simple, stable, decimal system of measurement units; the earliest meter unit chosen was teh length of a pendulum with a half-period of a second. October 10, 1989 Harold R. Kaufman and Raymond S. Robinson received U.S. patent 4 873 467 for what became familiarly known as the Kaufman ion source, which was adapted for ion drives for space probes and ion-beam sources for sputter deposition, etching, and cleaning.
