Equinox

An equinox is an astronomical event in which the plane of Earth's equator passes through the center of the Sun, making night and day of approximately equal length all over the planet. An equinox occurs twice each year, around 21 March and 23 September.

The equinoxes are the only times when the solar terminator (the "edge" between night and day) is perpendicular to the equator. As a result, the northern and southern hemispheres are equally illuminated.

In other words, the equinoxes are the only times when the subsolar point is on the equator, meaning that the Sun is exactly overhead at a point on the equatorial line. The subsolar point crosses the equator moving northward at the March equinox and southward at the September equinox.

The equinoxes, along with solstices, are directly related to the seasons of the year. In the northern hemisphere, the vernal equinox (March) conventionally marks the beginning of spring in most cultures and is considered the New Year in the Persian calendar, while the autumnal equinox (September) marks the beginning of autumn. In the southern hemisphere, the vernal equinox occurs in September and the autumnal equinox in March.

Noun

A noun (from Latin nōmen, literally meaning "name") is a word that functions as the name of some specific thing or set of things, such as living creatures, objects, places, actions, qualities, states of existence, or ideas.Linguistically, a noun is a member of a large, open part of speech whose members can occur as the main word in the subject of a clause, the object of a verb, or the object of a preposition.

Lexical categories (parts of speech) are defined in terms of the ways in which their members combine with other kinds of expressions. The syntactic rules for nouns differ from language to language. In English, nouns are those words which can occur with articles and attributive adjectives and can function as the head of a noun phrase.

History

Word classes (parts of speech) were described by Sanskrit grammarians from at least the 5th century BC. In Yāska's Nirukta, the noun (nāma) is one of the four main categories of words defined.

The Ancient Greek equivalent was ónoma (ὄνομα), referred to by Plato in the Cratylus dialog, and later listed as one of the eight parts of speech in The Art of Grammar, attributed to Dionysius Thrax (2nd century BC). The term used in Latin grammar was nōmen. All of these terms for "noun" were also words meaning "name". The English word noun is derived from the Latin term, through the Anglo-Norman noun.

Janet Yellen

Janet Louise Yellen (born August 13, 1946) is an American economist. She is the Chair of the Board of Governors of the Federal Reserve System, previously serving as Vice Chair from 2010 to 2014. Previously, she was President and Chief Executive Officer of the Federal Reserve Bank of San Francisco; Chair of the White House Council of Economic Advisers under President Bill Clinton; and business professor at the University of California, Berkeley, Haas School of Business.

Yellen's ability to connect economic theory to everyday life is considered one of the defining characteristics of her career, and President Obama cited her understanding of the high "human costs" of unemployment when he nominated her to succeed Ben Bernanke as Chair of the United States Federal Reserve. On January 6, 2014, the U.S. Senate confirmed Yellen's nomination. She was sworn in on February 3, 2014, making her the first woman to hold the position.

Early life and education

Yellen was born to a Jewish family in Brooklyn, New York, the daughter of Anna (née Blumenthal) and Julius Yellen, a physician. Her father's family originally came from the Polish town of Suwałki. She graduated from Fort Hamilton High School in the Bay Ridge section of Brooklyn. She graduated summa cum laude from Pembroke College (Brown University) with a degree in economics in 1967. At Brown, Yellen had switched her planned major from philosophy to economics and was particularly influenced by professors George Borts and Herschel Grossman. She received her Ph.D. in economics from Yale University in 1971 for a thesis titled Employment, output and capital accumulation in an open economy: a disequilibrium approach under the supervision of James Tobin and Nobel laureate Joseph Stiglitz, who later called Yellen one of his brightest and most memorable students. Two dozen economists earned their Ph.D from Yale in 1971, but Yellen was the only woman in that doctoral class.

Charlie Munger

Charles Thomas Munger (born January 1, 1924) is an American businessman, lawyer, investor, and philanthropist. He is vice chairman of Berkshire Hathaway, the conglomerate controlled by Warren Buffett; in this capacity, Buffett describes Charlie Munger as "my partner." Munger served as chairman of Wesco Financial Corporation from 1984 through 2011 (Wesco was approximately 80%-owned by Berkshire-Hathaway during that time). He is also the chairman of the Daily Journal Corporation, based in Los Angeles, California, and a director of Costco Wholesale Corporation.

Early life

Like Buffett, Munger is from Omaha, Nebraska. After studies in mathematics at the University of Michigan, and service in the U.S. Army Air Corps as a meteorologist, trained at Caltech, he entered Harvard Law School, where he was a member of the Harvard Legal Aid Bureau, without an undergraduate degree.

Career

Graduating in 1948 with an LL.B. magna cum laude, he moved with his family to California, where he joined the law firm Wright & Garrett (later Musick, Peeler & Garrett). In 1962 he founded and worked as a real estate attorney at Munger, Tolles & Olson LLP. He then gave up the practice of law to concentrate on managing investments and later partnered with Otis Booth in real estate development. He then partnered with Jack Wheeler to form Wheeler, Munger, and Company, an investment firm with a seat on the Pacific Coast Stock Exchange. He wound up Wheeler, Munger, and Co. in 1976, after losses of 31% in 1973 and 1974.
