Scientists From San Francisco
A scientist is a person who conducts scientific research to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have advanced degrees in an area of science and pursue careers in various sectors of the economy such as academia, industry, government, and nonprofit environments.''''

University Of California, Berkeley Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks.

Yaltah Menuhin
Yaltah Menuhin (7 October 1921 – 9 June 2001) was an American-born British pianist, artist and poet. Early life Yaltah was born in San Francisco, the youngest of three extraordinarily musically gifted children. Her siblings were Yehudi Menuhin and Hephzibah Menuhin. Through her father Moshe Menuhin, she descended from a distinguished rabbinical dynasty. Yaltah was named after her mother, Marutha's, home town of Yalta in Crimea. At the age of three, she became part of the rigorous regime already imposed on her siblings: the family employed tutors for the children, and Yaltah had her first piano lessons from the wife of the tutor in harmony and counterpoint. In 1960, she married (third marriage) an American pianist Joel Ryce who later retrained as a psychotherapist. Joel died in 1998. She was taken to Paris at the age of four when Yehudi and Hephzibah went to study there. Marcel Ciampi, engaged to teach Hephzibah, initially refused to entertain the notion of teaching Yaltah at s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
