The earliest recorded account of a circadian process dates from the 4th century B.C.E., when Androsthenes, a ship captain serving under Alexander the Great, described diurnal leaf movements of the tamarind tree. The observation of a circadian or diurnal process in humans is mentioned in Chinese medical texts dated to around the 13th century, including the Noon and Midnight Manual and the Mnemonic Rhyme to Aid in the Selection of Acu-points According to the Diurnal Cycle, the Day of the Month and the Season of the Year.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What ship captain described daily leaf movements?
Ah, so.. Androsthenes

PlayStation 3 uses the Cell microprocessor, designed by Sony, Toshiba and IBM, as its CPU, which is made up of one 3.2 GHz PowerPC-based "Power Processing Element" (PPE) and eight Synergistic Processing Elements (SPEs). The eighth SPE is disabled to improve chip yields. Only six of the seven SPEs are accessible to developers as the seventh SPE is reserved by the console's operating system. Graphics processing is handled by the NVIDIA RSX 'Reality Synthesizer', which can produce resolutions from 480i/576i SD up to 1080p HD. PlayStation 3 has 256 MB of XDR DRAM main memory and 256 MB of GDDR3 video memory for the RSX.

Two annual productions are especially notable: the Waa-Mu show, and the Dolphin show. Waa-Mu is an original musical, written and produced almost entirely by students. Children's theater is represented on campus by Griffin's Tale and Purple Crayon Players. Its umbrella organizationthe Student Theatre Coalition, or StuCo, organizes nine student theatre companies, multiple performance groups and more than sixty independent productions each year. Many Northwestern alumni have used these productions as stepping stones to successful television and film careers. Chicago's Lookingglass Theatre Company, for example, which began life in the Great Room in Jones Residential College, was founded in 1988 by several alumni, including David Schwimmer; in 2011, it won the Regional Tony Award.
