Nathan Lewis

Nathan S. Lewis is the George L. Argyros Professor of Chemistry at the California Institute of Technology. He specializes in functionalization of silicon and other semiconductor surfaces, as well as chemical sensing using chemiresistive sensor arrays. He obtained his B.S. and M.S. degrees also at Caltech under Harry B. Gray in 1977 studying the redox reactions of inorganic rhodium complexes. After that, he moved to the Massachusetts Institute of Technology for his Ph.D. in 1981 under Mark S. Wrighton studying semiconductor electrochemistry. He then went on to Stanford, first as an assistant professor from 1981 to 1985 and then as a tenured Associate Professor from 1986 to 1988 before relocating to Caltech.

Currently, Lewis is researching solar energy, and in July, 2010 was named as director of a U.S. Department of Energy Energy Innovation Hub, the Joint Center for Artificial Photosynthesis, to develop revolutionary methods to generate fuels directly from sunlight. He has been appointed chair of the Editorial Board for Energy and Environmental Science.

Lewis (Scottish Gaelic: Leòdhas, pronounced [ʎɔː.əs̪], also Isle of Lewis) is the northern part of Lewis and Harris, the largest island of the Western Isles or Outer Hebrides (an archipelago) of Scotland. The total area of Lewis is 683 square miles (1,770 km²).

Lewis is, in general, the lower lying part of the island, with the other part, Harris, being more mountainous. The flatter, more fertile land means Lewis contains the largest settlement, Stornoway, and three-quarters of the population of the Western Isles. Beyond human habitation, the island's diverse habitats are home to an assortment of flora and fauna, such as the golden eagle, red deer and seals and are recognised in a number of conservation areas.

Lewis is of Presbyterian tradition with a rich history, having once been part of the Norse Kingdom of Mann and the Isles. Today, life is very different from elsewhere in Scotland with Sabbath observance, the Gaelic language and peat cutting retaining more importance than elsewhere. Lewis has a rich cultural heritage as can be seen from its myths and legends as well as the local literary and musical traditions.

Lewis (satellite)

Lewis was an American satellite which was to have been operated by NASA as part of the Small Satellite Technology Initiative. It carried two experimental Earth imaging instruments, and an ultraviolet astronomy payload. Due to a design flaw it failed within three days of reaching orbit, before it became operational.

Lewis was a 288 kilograms (635 lb) spacecraft, which was designed to operate for between one and three years. It was built by TRW under a contract which was signed on 11 July 1994. Its primary instruments were the Hyperspectral Imager, the Linear Etalon Imaging Spectral Array and the Ultraviolet Cosmic Background experiment. A number of technology demonstration payloads were also flown.

Launch

Lewis was launched by a LMLV-1 (Athena I) rocket flying from Space Launch Complex 6 at the Vandenberg Air Force Base. The launch was originally scheduled to take place in September 1996, but it was delayed due to technical problems affecting the rocket. Launch finally occurred at 06:51:01 GMT on 23 August 1997, and Lewis was successfully placed into a parking orbit with an apogee of 134 kilometres (83 mi), a perigee of 124 kilometres (77 mi), and 97.5 degrees of inclination. Lewis was to have raised itself into a higher orbit, at an altitude of 523 kilometres (325 mi).

M. Lewis (Surrey cricketer)

M. Lewis (dates unknown) was an English amateur cricketer who made two appearances in first-class cricket matches during the 1773 season.

Career
