Niccolò Fontana Tartaglia



Niccolò Fontana Tartaglia (1499/1500, Brescia, Italy – December 13, 1557, Venice, Italy) was a mathematician, an engineer (designing fortifications), a surveyor (of topography, seeking the best means of defense or offense) and a bookkeeper from the then-Republic of Venice (now part of Italy). He published many books, including the first Italian translations of Archimedes and Euclid, and an acclaimed compilation of mathematics. Tartaglia was the first to apply mathematics to the investigation of the paths of cannonballs(commonly known as projectile motion); his work was later validated by Galileo's studies on falling bodies.

Niccolò Fontana was the son of Michele Fontana, a rider and deliverer. In 1505, Michele was murdered and Niccolò, his two siblings, and his mother were impoverished. Niccolò experienced further tragedy in 1512 when the French invaded Brescia during the War of the League of Cambrai. The militia of Brescia defended their city for seven days. When the French finally broke through, they took their revenge by massacring the inhabitants of Brescia. By the end of battle, over 45,000 residents were killed. During the massacre, a French soldier sliced Niccolò's jaw and palate. This made it impossible for Niccolò to speak normally, prompting the nickname "Tartaglia" (stammerer).

There is a story that Tartaglia learned only half the alphabet from a private tutor before funds ran out, and he had to learn the rest for himself. Be that as it may, he was essentially self-taught. He and his contemporaries, working outside the academies, were responsible for the spread of classic works in modern languages among the educated middle class.

Tartaglia was self taught in mathematics but, having an extraordinary ability, his mother was able to find him a patron. Ludovico Balbisonio took him to Padua to study there, but when he returned with his patron to Brescia he made himself unpopular by having an inflated opinion of himself. He left Brescia to earn his living teaching mathematics at Verona which he did between 1516 and 1518. Later, still in Verona, he taught at a school in the Palazzo Mizzanti but it is recorded that at that time he was married with a family, yet was very poor. He moved to Venice in 1534. As a lowly mathematics teacher in Venice, Tartaglia gradually acquired a reputation as a promising mathematician by participating successfully in a large number of debates.


His edition of Euclid in 1543, the first translation of the Elements into any modern European language, was especially significant. For two centuries Euclid had been taught from two Latin translations taken from an Arabic source; these contained errors in Book V, the Eudoxian theory of proportion, which rendered it unusable. Tartaglia's edition was based on Zamberti's Latin translation of an uncorrupted Greek text, and rendered Book V correctly. He also wrote the first modern and useful commentary on the theory. Later, the theory was an essential tool for Galileo, just as it had been for Archimedes.

Solution to cubic equations

Tartaglia is perhaps best known today for his conflicts with Gerolamo Cardano. Cardano nagged Tartaglia into revealing his solution to the cubic equations, by promising not to publish them. Several years later, Cardano happened to see unpublished work by Scipione del Ferro who independently came up with the same solution as Tartaglia. As the unpublished work was dated before Tartaglia's, Cardano decided his promise could be broken and included Tartaglia's solution in his next publication. Since Cardano credited his discovery, Tartaglia was extremely upset. He responded by publicly insulting Cardano.

The first person known to have solved cubic equations algebraically was del Ferro but he told nobody of his achievement. On his deathbed, however, del Ferro passed on the secret to his (rather poor) student Fior. For mathematicians of this time there was more than one type of cubic equation and Fior had only been shown by del Ferro how to solve one type, namely 'unknowns and cubes equal to numbers' or (in modern notation) x3 + ax = b. As negative numbers were not used this led to a number of other cases, even for equations without a square term. Fior began to boast that he was able to solve cubics and a challenge between him and Tartaglia was arranged in 1535. In fact Tartaglia had also discovered how to solve one type of cubic equation since his friend Zuanne da Coi had set two problems which had led Tartaglia to a general solution of a different type from that which Fior could solve, namely 'squares and cubes equal to numbers' or (in modern notation) x3 + ax2 = b. For the contest between Tartaglia and Fior, each man was to submit thirty questions for the other to solve. Fior was supremely confident that his ability to solve cubics would be enough to defeat Tartaglia but Tartaglia submitted a variety of different questions, exposing Fior as an, at best, mediocre mathematician. Fior, on the other hand, offered Tartaglia thirty opportunities to solve the 'unknowns and cubes' problem since he believed that he would be unable to solve this type, as in fact had been the case when the contest was set up. However, in the early hours of 13 February 1535, inspiration came to Tartaglia and he discovered the method to solve 'squares and cubes equal to numbers'. Tartaglia was then able to solve all thirty of Fior's problems in less than two hours. As Fior had made little headway with Tartaglia's questions, it was obvious to all who was the winner. Tartaglia did not take his prize for winning from Fior, however, the honour of winning was enough.


Volume of a tetrahedron

Tartaglia is also known for having given an expression (Tartaglia's formula) for the volume of a tetrahedron (incl. any irregular tetrahedra) as the Cayley–Menger determinant of the distance values measured pairwise between its four corners:



where d ij is the distance between vertices i and j. This is a generalization of Heron's formula for the area of a triangle

Triangle
Tartaglia is known for having devised a method to obtain binomial coefficients called Tartaglia's Triangle (also called Pascal's Triangle).

Buffet is often called the "Oracle of Omaha" or the "Sage of Omaha"and is noted for his adherence to the value investing philosophy and for his personal frugality despite his immense wealth. His 2006 annual salary was about $100,000, which is small compared to senior executive remuneration in comparable companies. In 2007, he earned a total compensation of $175,000, which included a base salary of just $100,000. He lives in the same house in the central Dundee neighborhood of Omaha that he bought in 1958 for $31,500, today valued at around $700,000. When Buffett spent $9.7 million of Berkshire's funds on a private jet in 1989, he jokingly named it "The Indefensible" because of his past criticisms of such purchases by other CEOs.

Buffet is also a notable philanthropist, having pledged to give away 85% of his fortune, then roughly $31 billion. He also serves as a member of the board of trustees at Grinnell College.

In 1999, Buffett was named the top money manager of the twentieth century in a survey by the Carson Group, ahead of Peter Lynch and John Templeton, and in 2007, he was listed among Time's 100 Most Influential People in the world.

Biography


Early life


Warren Buffett was born in Omaha, Nebraska on August 30, 1930, the son of Howard Buffett. He worked at his grandfather's grocery store. In 1943, Buffett filed his first income tax return, deducting his bicycle and watch as a work expense for $35 for his work as newspaper delivery boy. After his father was elected to Congress, Buffett was educated at Woodrow Wilson High School, Washington, D.C., where he graduated in 1947. In 1945, in his freshman year of high school, Buffett and a friend spent $25.00 to purchase a used pinball machine, which they placed in a barber shop. Within months, they owned three machines in different locations.

Buffett first enrolled at The Wharton School, University of Pennsylvania, (1947–1949) where he joined the Alpha Sigma Phi Fraternity. His father and uncles were Alpha Sigma Phi brothers from the chapter in Nebraska. In 1950 he transferred to the University of Nebraska where he received a B.S. in Economics.

Buffett then enrolled at Columbia Business School after learning that Benjamin Graham, (the author of The Intelligent Investor), and David Dodd, two well-known securities analysts, taught there. He then received a M.S. in Economics, Columbia University, in 1951.

In Buffett’s own words:

"I’m 15 percent Fisher and 85 percent Benjamin Graham.”

The basic ideas of investing are to look at stocks as business, use the market's fluctuations to your advantage, and seek a margin of safety. That’s what Ben Graham taught us. A hundred years from now they will still be the cornerstones of investing.


Career
Buffett was employed at 1951–1954 Buffett-Falk & Co., Omaha—Investment Salesman, then 1954–1956 Graham-Newman Corp., New York—Securities Analyst, then 1956–1969 Buffett Partnership, Ltd., Omaha—General Partner, then 1970–Present Berkshire Hathaway Inc, Omaha—Chairman, CEO.

In 1951, Buffett discovered Graham was on the board of GEICO insurance at the time. After taking a train to Washington, D.C. on a Saturday, Buffett knocked on the door of GEICO's headquarters until a janitor allowed him in. There, he met Lorimer Davidson, the vice president, who was to become a lasting influence on him and life-long friend. They talked for four hours about the insurance business. Davidson recalled that he found Buffett to be an “extraordinary man” after fifteen minutes. Buffett graduated from Columbia and wanted to work on Wall Street. Both his father and Ben Graham urged him not to. Buffett offered to work for Graham for free, but Graham refused.

Returning to Omaha, he purchased a Sinclair Texaco gas station as a side investment, but that venture did not work out as well as he had hoped. Meanwhile, he worked as a stockbroker. During that time, Buffett also took a Dale Carnegie public speaking course. Using what he learned, he felt confident enough to teach a night class at the University of Nebraska, "Investment Principles." The average age of the students he taught was more than twice his own.

In 1952, Buffett married Susan Thompson. In 1953, Susan and Warren Buffett had their first child, Susan Alice Buffett. In 1954, Benjamin Graham offered Buffett a job at his partnership with a starting salary of $12,000 a year. Here, he worked closely with Walter Schloss. Graham, who was a tough man to work for, was adamant that a stock provide a wide margin of safety after weighting the trade-off between its price and intrinsic value. Graham’s demand that a stock be worth more than its price made sense to Buffett, but it also made him question whether the criteria were too stringent, causing them to miss out on some big winners that had more qualitative values. Susan and Warren Buffett had their second child, Howard Graham Buffett. In 1956, Benjamin Graham retired, and closed his partnership. Buffett's personal savings were now over $140,000. Buffett returned home to Omaha and created Buffett Partnership Ltd., an investment partnership.

In 1957, Buffett had three partnerships operating the entire year. Buffett purchased a five-bedroom stucco house in Omaha, in which he still lives, for $31,500. In 1958, Susan and Warren Buffett had their third child, Peter Andrew Buffett. Buffett had five partnerships operating the entire year. In 1959, Buffett had six partnerships operating the entire year. Buffett was introduced to Charlie Munger. In 1960, Buffett had seven partnerships operating the entire year. The partnerships were: Buffett Associates, Buffett Fund, Dacee, Emdee, Glenoff, Mo-Buff, and Underwood. Buffett asked one of his partners, a doctor, to find ten other doctors who would be willing to invest $10,000 each in his partnership. Eventually, eleven doctors agreed to invest. In 1961, Buffett revealed that Sanborn Map Company accounted for 35% of the partnerships' assets. Buffett explained that in 1958, Sanborn sold at $45 per share when the value of the Sanborn investment portfolio was $65 per share. This meant buyers valued Sanborn at "minus $20" per share, and buyers were unwilling to pay more than 70 cents on the dollar for an investment portfolio with a map business thrown in for nothing. Buffett revealed that he earned a spot on the board of Sanborn.


Becoming a millionaire
In 1962, Buffett became a millionaire, because of Buffett's partnerships, which in January 1962, had in excess of $7,178,500, of which over $1,025,000 belonged to Buffett. Buffett merged all partnerships into one partnership. Buffett discovered a textile manufacturing firm, Berkshire Hathaway. Buffett's partnerships began purchasing shares at $7.60 per share. In 1965, when Buffett's partnerships aggressively began purchasing Berkshire, they paid $14.86 per share while the company had working capital (current assets minus current liabilities) of $19 per share. This did not include the value of fixed assets (factory and equipment). Buffett took control of Berkshire Hathaway at the board meeting and named a new president, Ken Chace, to run the company. In 1966, Buffett closed the partnership to new money. Buffett wrote in his letter:

unless it appears that circumstances have changed (under some conditions added capital would improve results) or unless new partners can bring some asset to the partnership other than simply capital, I intend to admit no additional partners to BPL.

In a second letter, Buffett announced his first investment in a private business — Hochschild, Kohn and Co, a privately owned Baltimore department store. In 1967, Berkshire paid out its first and only dividend of 10 cents. In 1969, following his most successful year, Buffett liquidated the partnership and transferred their assets to his partners. Among the assets paid out were shares of Berkshire Hathaway. In 1970, as chairman of Berkshire Hathaway, Buffett began writing his now-famous annual letters to shareholders.

However, he lived solely on his salary of $50,000 per year, and his outside investment income. In 1979, Berkshire began the year trading at $775 per share, and ended at $1,310. Buffett's net worth reached $620 million, placing him on the Forbes 400 for the first time.

In 2006, Buffett announced in June that he gradually would give away 85% of his Berkshire holdings to five foundations in annual gifts of stock, starting in July 2006. The largest contribution would go to the Bill and Melinda Gates Foundation.

In 2007, in a letter to shareholders, Buffett announced that he was looking for a younger successor, or perhaps successors, to run his investment business. Buffett had previously selected Lou Simpson, who runs investments at Geico, to fill that role. However, Simpson is only six years younger than Buffett.

In 2008, Buffett became the richest man in the world dethroning Bill Gates, worth $62 billion according to Forbes, and $58 billion according to Yahoo. Bill Gates had been number 1 on the Forbes list for 13 consecutive years.


Business

Acquisitions


In 1973, Berkshire began to acquire stock in the Washington Post Company. Buffett became close friends with Katharine Graham, who controlled the company and its flagship newspaper, and became a member of its board of directors.

In 1974, the SEC opened a formal investigation into Warren Buffett and Berkshire's acquisition of WESCO, due to possible conflict of interest. No charges were brought.

In 1977, Berkshire indirectly purchased the Buffalo Evening News for $32.5 million. Antitrust charges started, instigated by its rival, the Buffalo Courier-Express. Both papers lost money, until the Courier-Express folded in 1982.

In 1979, Berkshire began to acquire stock in ABC. With the stock trading at $290 per share, Buffett's net worth neared $140 million. Capital Cities' announced $3.5 billion purchase of ABC on March 18, 1985, surprising the media industry, as ABC was some four times bigger than Capital Cities was at the time. Berkshire Hathaway chairman Warren Buffett helped financed the deal in return for a 25 percent stake in the combined company. The newly merged company, known as Capital Cities/ABC (or CapCities/ABC), was forced to sell off some stations due to FCC ownership rules. Also, the two companies owned several radio stations in the same markets.

In 1987, Berkshire Hathaway purchased 12% stake in Salomon Inc., making it the largest shareholder and Buffett the director. In 1990, a scandal involving John Gutfreund (former CEO of Salomon Brothers) surfaced. A rogue trader, Paul Mozer, was submitting bids in excess of what was allowed by the Treasury rules. When this was discovered and brought to the attention of Gutfreund, he did not immediately suspend the rogue trader. Gutfreund left the company in August 1991. Buffett became CEO of Salomon until the crisis passed; on September 4 1991, he testified before Congress.

In 1988, Buffett began buying stock in Coca-Cola Company, eventually purchasing up to 7 percent of the company for $1.02 billion. It would turn out to be one of Berkshire's most lucrative investments, and one which it still holds. In 2002, Buffett entered in $11 billion worth of forward contracts to deliver U.S. dollars against other currencies. By April 2006, his total gain on these contracts was over $2 billion.

In 1998, he acquired General Re, (in a rare move, for stock). In 2002, Buffett became involved with Maurice R. Greenberg at AIG, with General Re providing reinsurance. On March 15, 2005, AIG's board forced Greenberg to resign from his post as Chairman and CEO under the shadow of criticism from Eliot Spitzer, attorney general of the state of New York. On February 9, 2006, AIG and the New York State Attorney General's office agreed to a settlement in which AIG would pay a fine of $1.6 billion.

In 2009, Warren Buffett invested $2.6 billion as a part of Swiss Re's raising equity captal. Berkshire Hathaway already owns a 3% stake, with rights to own more than 20%.


Late 2000s recession
Buffett ran into criticism, during the subprime crisis of 2007–2008, part of the late 2000s recession, that he has allocated capital too early resulting in suboptimal deals.

Buffett has called the 2007—present downturn in the financial sector "poetic justice".

Buffett's Berkshire Hathaway suffered a 77% drop in earnings during Q3 2008 and several of his recent deals appear to be running into large mark-to-market losses.

Berkshire Hathaway acquired 10% perpetual preferred stock of Goldman Sachs at $123 only for it to fall to below $60. Furthermore some of Buffett's Index put options (European exercise at expiry only) that he wrote (sold) are currently running around $6.73 billion mark-to-market losses.The scale of the potential loss prompted the SEC to demand that Berkshire produce, "a more robust disclosure" of factors used to value the contracts.

Buffett also helped Dow Chemical pay for its $18.8 billion takeover of Rohm & Haas. He thus became the single largest shareholder in the enlarged group with his Berkshire Hathaway, which provided $3 billion, underlining his instrumental role during the current crisis in debt and equity markets.

In October 2008, the media reported that Warren Buffett had agreed to buy General Electric (GE) preferred stock, when it was trading in the mid 20s of dollar. The operation included extra special incentives: he received an option to buy 3 billion GE at $22.25 in the next five years and also received a 10% dividend (callable within three years). However, shortly after, GE gave up tens of billions in market capitalization and just bounced off a low of $8.80 in February 23, 2009, a price that has not been seen in over a decade. GE's stock price continued to fall after that point, and by early March, for example, it had declined to an 18 year low. Events like these have prompted a wave of criticism against Berkshire Hathaway and Warren Buffett. In February 2009, Warren Buffett unloaded part of Procter & Gamble Co and Johnson & Johnson shares from his portfolio..

Some have claimed that there is a financial incentive for Berkshire Hathaway to keep the myth that Buffett is an “oracle” alive and that the company is dependent on the Warren Buffett myth: that exaggerated sense of comfort investors share when it comes to Buffett’s beliefs and recommendations. In addition to suggestions of mistiming, questions have been raised as to the wisdom in keeping some of Berkshire's major holdings including The Coca-Cola Company (NYSE:KO) which in 1998 peaked at $86. Buffett discussed the difficulties of knowing when to sell in the company's 2004 annual report: "That may seem easy to do when one looks through an always-clean, rear-view mirror. Unfortunately, however, it’s the windshield through which investors must peer, and that glass is invariably fogged." In March 2009, Buffett stated in a cable television interview that the economy had "fallen off a cliff... Not only has the economy slowed down a lot, but people have really changed their habits like I haven't seen." Additionally, Buffett fears we may revisit a 1970s level of inflation, which led to a painful stagflation that lasted many years.


Personal life

Buffett married Susan Thompson in 1952. They had three children, Susie, Howard, and Peter. The couple began living separately in 1977, although they remained married until her death in July 2004. Their daughter Susie lives in Omaha and does charitable work through the Susan A. Buffett Foundation and is a national board member of Girls, Inc. In 2006, on his seventy-sixth birthday, he married his never-married longtime-companion, Astrid Menks, who was then sixty years old. She had lived with him since his wife's departure in 1977 to San Francisco. It was Susan Buffett who arranged for the two to meet before she left Omaha to pursue her singing career. All three were close and holiday cards to friends were signed "Warren, Susie and Astrid". Susan Buffett briefly discussed this relationship in an interview on the Charlie Rose Show shortly before her death, in a rare glimpse into Buffett's personal life.

He remains an avid player of the card game bridge, which he learned from Sharon Osberg, and plays with her and Bill Gates. He spends twelve hours a week playing the game. In 2006, he sponsored a bridge match for the Buffett Cup. Modeled on the Ryder Cup in golf, held immediately before it, and in the same city, a team of twelve bridge players from the United States took on twelve Europeans in the event.

Warren Buffett works with Christopher Webber on an animated series with DiC Entertainment chief Andy Heyward. According to information presented by Buffett at the Berkshire Hathaway annual meeting on May 6, 2006, the series will feature Buffett and Munger in roles and the series will teach children healthy financial habits for life. Cartoon drawings of Buffett and Munger were displayed throughout the events during the weekend as well as in a special animated movie from Heyward, displayed before the meeting.

Buffett has described himself as agnostic when it comes to religious beliefs. In December 2006 it was reported that Buffett does not carry a cell phone, does not have a computer at his desk, and drives his own automobile, a Cadillac DTS.

Buffett's DNA report revealed that his paternal ancestors hail from northern Scandinavia, while his maternal ancestors most likely have roots in Iberia or Estonia. Despite widespread suggestions to the contrary, and the casual friendship which has developed between their families, Warren Buffett has no clear relation to the well-known singer Jimmy Buffett.


Politics

In addition to other political contributions over the years, Buffett has formally endorsed and made campaign contributions to Barack Obama's presidential campaign. On July 2, 2008, Buffett attended a $28,500 per plate fundraiser for Mr. Obama's campaign in Chicago hosted by Mr. Obama's National Finance Chair, Penny Pritzker and her husband, as well as Obama advisor Valerie Jarrett.Buffett backed Obama for president, and intimated that John McCain's views on social justice were so far from his own that McCain would need a "lobotomy" for Buffett to change his endorsement. During the second 2008 U.S. presidential debate, candidates John McCain and Barack Obama, after being asked first by presidential debate mediator Tom Brokaw, both mentioned Buffett as a possible future Secretary of the Treasury. Later, in the third and final presidential debate, Obama mentioned Buffett as a potential economic advisor. Buffett was also finance advisor to California Republican Governor Arnold Schwarzenegger during his 2003 election campaign.


Writings
Warren Buffett's writings include his annual reports and various articles.

He warned about the pernicious effects of inflation:

“ The arithmetic makes it plain that inflation is a far more devastating tax than anything that has been enacted by our legislatures. The inflation tax has a fantastic ability to simply consume capital. It makes no difference to a widow with her savings in a 5 percent passbook account whether she pays 100 percent income tax on her interest income during a period of zero inflation, or pays no income taxes during years of 5 percent inflation. ”

In his article The Superinvestors of Graham-and-Doddsville, Buffett refuted the academic Efficient-market hypothesis, that beating the S&P 500 was "pure chance", by highlighting a number of students of the Graham and Dodd value investing school of thought. In addition to himself, Buffett named Walter J. Schloss, Tom Knapp, Ed Anderson (Tweedy, Brown Inc.), Bill Ruane (Sequoia Fund, Inc.), Charles Munger (Buffett's own business partner at Berkshire), Rick Guerin (Pacific Partners, Ltd.), and Stan Perlmeter (Perlmeter Investments)

In his November, 1999 Fortune article, he warned of investors' unrealistic expectations:

“ Let me summarize what I've been saying about the stock market: I think it's very hard to come up with a persuasive case that equities will over the next 17 years perform anything like--anything like--they've performed in the past 17. If I had to pick the most probable return, from appreciation and dividends combined, that investors in aggregate--repeat, aggregate--would earn in a world of constant interest rates, 2% inflation, and those ever hurtful frictional costs, it would be 6%. ”


Philanthropy
The following quotation from 1988, respectively, highlights Warren Buffett's thoughts on his wealth and why he long planned to re-allocate it:

“ I don't have a problem with guilt about money. The way I see it is that my money represents an enormous number of claim checks on society. It's like I have these little pieces of paper that I can turn into consumption. If I wanted to, I could hire 10,000 people to do nothing but paint my picture every day for the rest of my life. And the GNP would go up. But the utility of the product would be zilch, and I would be keeping those 10,000 people from doing AIDS research, or teaching, or nursing. I don't do that though. I don't use very many of those claim checks. There's nothing material I want very much. And I'm going to give virtually all of those claim checks to charity when my wife and I die. (Lowe 1997:165–166) ”

From a NY Times article: "I don't believe in dynastic wealth," Warren Buffett said, calling those who grow up in wealthy circumstances "members of the lucky sperm club." Buffett has written several times of his belief that, in a market economy, the rich earn outsized rewards for their talents:

“ A market economy creates some lopsided payoffs to participants. The right endowment of vocal chords, anatomical structure, physical strength, or mental powers can produce enormous piles of claim checks (stocks, bonds, and other forms of capital) on future national output. Proper selection of ancestors similarly can result in lifetime supplies of such tickets upon birth. If zero real investment returns diverted a bit greater portion of the national output from such stockholders to equally worthy and hardworking citizens lacking jackpot-producing talents, it would seem unlikely to pose such an insult to an equitable world as to risk Divine Intervention. ”

His children will not inherit a significant proportion of his wealth. These actions are consistent with statements he has made in the past indicating his opposition to the transfer of great fortunes from one generation to the next. Buffett once commented, "I want to give my kids just enough so that they would feel that they could do anything, but not so much that they would feel like doing nothing".

In 2006, he auctioned his 2001 Lincoln Town Car on eBay to raise money for Girls, Inc.

In 2007, he auctioned a luncheon with himself that raised a final bid of $650,100 for a charity.

In 2006, he announced a plan to give away his fortune to charity, with 83% of it going to the Bill & Melinda Gates Foundation. In June 2006, Buffett gave approximately 10 million Berkshire Hathaway Class B shares to the Bill & Melinda Gates Foundation (worth approximately USD 30.7 billion as of 23 June 2006)making it the largest charitable donation in history and Buffett one of the leaders in the philanthrocapitalism revolution. The foundation will receive 5% of the total donation on an annualised basis each July, beginning in 2006. Buffett also will join the board of directors of the Gates Foundation, although he does not plan to be actively involved in the foundation's investments.

He also announced plans to contribute additional Berkshire stock valued at approximately $6.7 billion to the Susan Thompson Buffett Foundation and to other foundations headed by his three children. This is a significant shift from previous statements Buffett has made, having stated that most of his fortune would pass to his Buffett Foundation. The bulk of the estate of his wife, valued at $2.6 billion, went to that foundation when she died in 2004.

He also pledged $50-million to the Nuclear Threat Initiative, in Washington, where he has served as an adviser since 2002.

On 27 June 2008, Zhao Danyang, a general manager at Pure Heart China Growth Investment Fund, won the 2008 5-day online "Power Lunch with Warren Buffett" charity auction with a bid of $2,110,100. Auction proceeds benefit the San Francisco Glide Foundation.


Public positions
Buffett's speeches are known for mixing business discussions with humor. Each year, Buffett presides over Berkshire Hathaway's annual shareholder meeting in the Qwest Center in Omaha, Nebraska, an event drawing over 20,000 visitors from both United States and abroad, giving it the nickname "Woodstock of Capitalism". Berkshire's annual reports and letters to shareholders, prepared by Buffett, frequently receive coverage by the financial media. Buffett's writings are known for containing literary quotes ranging from the Bible to Mae West, as well as Midwestern advice, and numerous jokes. Various websites extol Buffett's virtues while others decry Buffett’s business models or dismiss his investment advice and decisions.


Buffett and tobacco
During the RJR Nabisco, Inc. hostile takeover fight in 1987, Buffett was quoted as telling John Gutfreund:

I’ll tell you why I like the cigarette business. It costs a penny to make. Sell it for a dollar. It’s addictive. And there’s fantastic brand loyalty.

However, by 1994, Buffett had changed his stance on tobacco. Speaking at Berkshire Hathaway Inc.'s 1994 annual meeting, Buffett said investments in tobacco are:

fraught with questions that relate to societal attitudes and those of the present administration. I would not like to have a significant percentage of my net worth invested in tobacco businesses. The economy of the business may be fine, but that doesn't mean it has a bright future. ”


Buffett and coal
In 2007, Buffett's PacifiCorp, a subsidiary of his MidAmerican Energy Company, cancelled six proposed coal-fired power plants. These included Utah's Intermountain Power Project Unit 3, Jim Bridger Unit 5, and four proposed plants previously included in PacifiCorp's Integrated Resource Plan. The cancellations came in the wake of pressure from regulators and citizen groups, including a petition drive organized by Salt Lake City commercial real estate broker Alexander Lofft and directed at Buffett personally. The 1,600 petitioners, who described themselves in a letter to Buffett as "a collection of citizens, business owners and managers, service professionals, public servants, and organization representatives ... your friends and new customers here in Utah," explained that, in their view, any further expansion of coal generation in Utah would "compromise our health, obscure our viewsheds, shrink and contaminate our watersheds, and thin out our most beloved snowpack," concluding that "our attractiveness as a place to live and work is also threatened, and so is our economic competitiveness as a major metro area and a state, compromising our recent gains in income and property values."


Klamath river
American Indian tribes, and salmon fisherman sought to win support from Warren Buffett, for a proposal to remove four hydroelectric dams from the Klamath River. He had David Sokol respond that the FERC would decide the question.


Trade deficit
Buffett views the United States' expanding trade deficit as an alarming trend that will devalue the U.S. dollar and U.S. assets. He believes that the U.S. dollar will lose value in the long run, as a result of putting a larger portion of ownership of U.S. assets, in the hands of foreigners.

In his letter to shareholders in March, 2005, Warren Buffett predicted that in another ten years’ time the net ownership of the U.S. by outsiders would amount to $11 trillion. “Americans … would chafe at the idea of perpetually paying tribute to their creditors and owners abroad. A country that is now aspiring to an ‘ownership society’ will not find happiness in—and I’ll use hyperbole here for emphasis—a 'sharecropping society’.” Author Ann Pettifor has adopted the image in her writings and has stated: "He is right. And so the thing we must fear most now, is not just the collapse of banks and investment funds, or of the international financial architecture, but of a 'sharecropper society, angry at its downfall."


Dollar and gold
This induced Buffett to enter the foreign currency market for the first time in 2002. However, he substantially reduced his stake in 2005 as changing interest rates increased the costs of holding currency contracts. Buffett continues to be bearish on the dollar, and says he is looking to make acquisitions of companies which derive a substantial portion of their revenues from outside the United States.

Buffett emphasized the non-productive aspect of gold in 1998 at Harvard:

“ It gets dug out of the ground in Africa, or someplace. Then we melt it down, dig another hole, bury it again and pay people to stand around guarding it. It has no utility. Anyone watching from Mars would be scratching their head. ”

In 1977 Buffett was also quoted as saying about stocks, gold, farmland, and inflation:

“ stocks are probably still the best of all the poor alternatives in an era of inflation—at least they are if you buy in at appropriate prices. ”


Taxes

Buffett stated that he only paid 19% of his income for 2006 ($48.1 million) in total federal taxes, while his employees paid 33% of theirs, despite making much less money. Buffett favors the inheritance tax, saying that repealing it would be like "choosing the 2020 Olympic team by picking the eldest sons of the gold-medal winners in the 2000 Olympics". In 2007, Buffett testified before the Senate and urged them to preserve the estate tax so as to avoid a plutocracy.

Buffett believes government should not be in the business of gambling, or legalize casinos, believing it to be a tax on ignorance.


Expensing of stock options
He has been a strong proponent of stock option expensing, on the Income Statement. At the 2004 annual meeting, he compared the United States Congress, and the Securities and Exchange Commission’s decision to override FASB, who wanted to consider company-issued stock-option compensation as an expense, to a bill proposed in the Indiana House of Representatives to change Pi from 3.14159 to 3.2 .

When a company gives something of value to its employees in return for their services, it is clearly a compensation expense. And if expenses don't belong in the earnings statement, where in the world do they belong?


Investment in China

Buffett invested in PetroChina Company Limited and in a rare move, posted a commentary on Berkshire Hathaway's website stating why he would not divest from the company despite calls from some activists to do so. (He did, however, sell this stake, apparently for purely financial reasons.) Buffett believes that the world is nearing its maximum capacity of oil production and that gradually depleted oil fields could reduce the amount produced.


Books about Warren Buffett

Numerous books have been written about Warren Buffett and his investment strategies. In October 2008, USA Today reported that there were at least 47 books in print with Buffett's name in the title. The article quoted the CEO of Borders Books, George Jones, as saying that the only other living persons named in as many book titles were U.S. presidents, major world political figures, and the Dalai Lama. Buffett said that his own personal favorite is a collection of his essays called The Essays of Warren Buffett, which he described as "a coherent rearrangement of ideas from my annual report letters" as edited by Larry Cunningham.

Best-selling or otherwise notable books about Buffett include the following:

Robert Hagstrom, The Warren Buffett Way. (As of 2008, the bestselling book about Buffett.)
Alice Schroeder, The Snowball: Warren Buffett and the Business of Life. (Written with Buffett's cooperation.)
Mary Buffett and David Clark, Buffettology and four subsequent books. (Combined sales of more than 1.5 million copies.)
Janet Lowe, Warren Buffett Speaks: Wit and Wisdom from the Word's Greatest Investor.

Barack Hussein Obama II (pronounced /bəˈrɑːk hʊˈseɪn oʊˈbɑːmə/; born August 4, 1961) is the forty-fourth and current President of the United States. He is the first African American to hold the office. Obama was the junior United States Senator from Illinois from January 3, 2005 until his resignation on November 16, 2008, following his election to the presidency. He was sworn into office on January 20, 2009 in an inaugural ceremony at the United States Capitol in Washington D.C..

Obama is a graduate of Columbia University and Harvard Law School, where he was the first African-American president of the Harvard Law Review. He worked as a community organizer, and practiced as a civil rights attorney in Chicago before serving three terms in the Illinois Senate from 1997 to 2004. He also taught Constitutional Law at the University of Chicago Law School from 1992 to 2004. Following an unsuccessful bid for a seat in the U.S. House of Representatives in 2000, Obama was elected to the Senate in November 2004. Obama delivered the keynote address at the Democratic National Convention in July 2004.

As a member of the Democratic minority in the 109th Congress, Obama helped create legislation to control conventional weapons and to promote greater public accountability in the use of federal funds. He also made official trips to Eastern Europe, the Middle East, and Africa. During the 110th Congress, he helped create legislation regarding lobbying and electoral fraud, climate change, nuclear terrorism, and care for U.S. military personnel returning from combat assignments in Iraq and Afghanistan.


President Barack Obama's Inaugural Address

My fellow citizens:

I stand here today humbled by the task before us, grateful for the trust you have bestowed, mindful of the sacrifices borne by our ancestors. I thank President Bush for his service to our nation, as well as the generosity and cooperation he has shown throughout this transition.

Forty-four Americans have now taken the presidential oath. The words have been spoken during rising tides of prosperity and the still waters of peace. Yet, every so often the oath is taken amidst gathering clouds and raging storms. At these moments, America has carried on not simply because of the skill or vision of those in high office, but because We the People have remained faithful to the ideals of our forbearers, and true to our founding documents.

So it has been. So it must be with this generation of Americans.

That we are in the midst of crisis is now well understood. Our nation is at war, against a far-reaching network of violence and hatred. Our economy is badly weakened, a consequence of greed and irresponsibility on the part of some, but also our collective failure to make hard choices and prepare the nation for a new age. Homes have been lost; jobs shed; businesses shuttered. Our health care is too costly; our schools fail too many; and each day brings further evidence that the ways we use energy strengthen our adversaries and threaten our planet.

These are the indicators of crisis, subject to data and statistics. Less measurable but no less profound is a sapping of confidence across our land - a nagging fear that America's decline is inevitable, and that the next generation must lower its sights.

Today I say to you that the challenges we face are real. They are serious and they are many. They will not be met easily or in a short span of time. But know this, America - they will be met.

On this day, we gather because we have chosen hope over fear, unity of purpose over conflict and discord.

On this day, we come to proclaim an end to the petty grievances and false promises, the recriminations and worn out dogmas, that for far too long have strangled our politics.

We remain a young nation, but in the words of Scripture, the time has come to set aside childish things. The time has come to reaffirm our enduring spirit; to choose our better history; to carry forward that precious gift, that noble idea, passed on from generation to generation: the God-given promise that all are equal, all are free, and all deserve a chance to pursue their full measure of happiness.

In reaffirming the greatness of our nation, we understand that greatness is never a given. It must be earned. Our journey has never been one of short-cuts or settling for less. It has not been the path for the faint-hearted - for those who prefer leisure over work, or seek only the pleasures of riches and fame. Rather, it has been the risk-takers, the doers, the makers of things - some celebrated but more often men and women obscure in their labor, who have carried us up the long, rugged path towards prosperity and freedom.

For us, they packed up their few worldly possessions and traveled across oceans in search of a new life.

For us, they toiled in sweatshops and settled the West; endured the lash of the whip and plowed the hard earth.

For us, they fought and died, in places like Concord and Gettysburg; Normandy and Khe Sahn.

Time and again these men and women struggled and sacrificed and worked till their hands were raw so that we might live a better life. They saw America as bigger than the sum of our individual ambitions; greater than all the differences of birth or wealth or faction.

This is the journey we continue today. We remain the most prosperous, powerful nation on Earth. Our workers are no less productive than when this crisis began. Our minds are no less inventive, our goods and services no less needed than they were last week or last month or last year. Our capacity remains undiminished. But our time of standing pat, of protecting narrow interests and putting off unpleasant decisions - that time has surely passed. Starting today, we must pick ourselves up, dust ourselves off, and begin again the work of remaking America.

For everywhere we look, there is work to be done. The state of the economy calls for action, bold and swift, and we will act - not only to create new jobs, but to lay a new foundation for growth. We will build the roads and bridges, the electric grids and digital lines that feed our commerce and bind us together. We will restore science to its rightful place, and wield technology's wonders to raise health care's quality and lower its cost. We will harness the sun and the winds and the soil to fuel our cars and run our factories. And we will transform our schools and colleges and universities to meet the demands of a new age. All this we can do. And all this we will do.

Now, there are some who question the scale of our ambitions - who suggest that our system cannot tolerate too many big plans. Their memories are short. For they have forgotten what this country has already done; what free men and women can achieve when imagination is joined to common purpose, and necessity to courage.

What the cynics fail to understand is that the ground has shifted beneath them - that the stale political arguments that have consumed us for so long no longer apply. The question we ask today is not whether our government is too big or too small, but whether it works - whether it helps families find jobs at a decent wage, care they can afford, a retirement that is dignified. Where the answer is yes, we intend to move forward. Where the answer is no, programs will end. And those of us who manage the public's dollars will be held to account - to spend wisely, reform bad habits, and do our business in the light of day - because only then can we restore the vital trust between a people and their government.

Nor is the question before us whether the market is a force for good or ill. Its power to generate wealth and expand freedom is unmatched, but this crisis has reminded us that without a watchful eye, the market can spin out of control - and that a nation cannot prosper long when it favors only the prosperous. The success of our economy has always depended not just on the size of our Gross Domestic Product, but on the reach of our prosperity; on our ability to extend opportunity to every willing heart - not out of charity, but because it is the surest route to our common good.

As for our common defense, we reject as false the choice between our safety and our ideals. Our Founding Fathers, faced with perils we can scarcely imagine, drafted a charter to assure the rule of law and the rights of man, a charter expanded by the blood of generations. Those ideals still light the world, and we will not give them up for expedience's sake. And so to all other peoples and governments who are watching today, from the grandest capitals to the small village where my father was born: know that America is a friend of each nation and every man, woman, and child who seeks a future of peace and dignity, and that we are ready to lead once more.

Recall that earlier generations faced down fascism and communism not just with missiles and tanks, but with sturdy alliances and enduring convictions. They understood that our power alone cannot protect us, nor does it entitle us to do as we please. Instead, they knew that our power grows through its prudent use; our security emanates from the justness of our cause, the force of our example, the tempering qualities of humility and restraint.

We are the keepers of this legacy. Guided by these principles once more, we can meet those new threats that demand even greater effort - even greater cooperation and understanding between nations. We will begin to responsibly leave Iraq to its people, and forge a hard-earned peace in Afghanistan. With old friends and former foes, we will work tirelessly to lessen the nuclear threat, and roll back the specter of a warming planet. We will not apologize for our way of life, nor will we waver in its defense, and for those who seek to advance their aims by inducing terror and slaughtering innocents, we say to you now that our spirit is stronger and cannot be broken; you cannot outlast us, and we will defeat you.

For we know that our patchwork heritage is a strength, not a weakness. We are a nation of Christians and Muslims, Jews and Hindus - and non-believers. We are shaped by every language and culture, drawn from every end of this Earth; and because we have tasted the bitter swill of civil war and segregation, and emerged from that dark chapter stronger and more united, we cannot help but believe that the old hatreds shall someday pass; that the lines of tribe shall soon dissolve; that as the world grows smaller, our common humanity shall reveal itself; and that America must play its role in ushering in a new era of peace.

To the Muslim world, we seek a new way forward, based on mutual interest and mutual respect. To those leaders around the globe who seek to sow conflict, or blame their society's ills on the West - know that your people will judge you on what you can build, not what you destroy. To those who cling to power through corruption and deceit and the silencing of dissent, know that you are on the wrong side of history; but that we will extend a hand if you are willing to unclench your fist.

To the people of poor nations, we pledge to work alongside you to make your farms flourish and let clean waters flow; to nourish starved bodies and feed hungry minds. And to those nations like ours that enjoy relative plenty, we say we can no longer afford indifference to suffering outside our borders; nor can we consume the world's resources without regard to effect. For the world has changed, and we must change with it.

As we consider the road that unfolds before us, we remember with humble gratitude those brave Americans who, at this very hour, patrol far-off deserts and distant mountains. They have something to tell us today, just as the fallen heroes who lie in Arlington whisper through the ages. We honor them not only because they are guardians of our liberty, but because they embody the spirit of service; a willingness to find meaning in something greater than themselves. And yet, at this moment - a moment that will define a generation - it is precisely this spirit that must inhabit us all.

For as much as government can do and must do, it is ultimately the faith and determination of the American people upon which this nation relies. It is the kindness to take in a stranger when the levees break, the selflessness of workers who would rather cut their hours than see a friend lose their job which sees us through our darkest hours. It is the firefighter's courage to storm a stairway filled with smoke, but also a parent's willingness to nurture a child, that finally decides our fate.

Our challenges may be new. The instruments with which we meet them may be new. But those values upon which our success depends - hard work and honesty, courage and fair play, tolerance and curiosity, loyalty and patriotism - these things are old. These things are true. They have been the quiet force of progress throughout our history. What is demanded then is a return to these truths. What is required of us now is a new era of responsibility - a recognition, on the part of every American, that we have duties to ourselves, our nation, and the world, duties that we do not grudgingly accept but rather seize gladly, firm in the knowledge that there is nothing so satisfying to the spirit, so defining of our character, than giving our all to a difficult task.

This is the price and the promise of citizenship.

This is the source of our confidence - the knowledge that God calls on us to shape an uncertain destiny.

This is the meaning of our liberty and our creed - why men and women and children of every race and every faith can join in celebration across this magnificent mall, and why a man whose father less than sixty years ago might not have been served at a local restaurant can now stand before you to take a most sacred oath.

So let us mark this day with remembrance, of who we are and how far we have traveled. In the year of America's birth, in the coldest of months, a small band of patriots huddled by dying campfires on the shores of an icy river. The capital was abandoned. The enemy was advancing. The snow was stained with blood. At a moment when the outcome of our revolution was most in doubt, the father of our nation ordered these words be read to the people:

"Let it be told to the future world...that in the depth of winter, when nothing but hope and virtue could survive...that the city and the country, alarmed at one common danger, came forth to meet [it]."

America. In the face of our common dangers, in this winter of our hardship, let us remember these timeless words. With hope and virtue, let us brave once more the icy currents, and endure what storms may come. Let it be said by our children's children that when we were tested we refused to let this journey end, that we did not turn back nor did we falter; and with eyes fixed on the horizon and God's grace upon us, we carried forth that great gift of freedom and delivered it safely to future generations.
