Самый богатый и скромный учитель

Дэвид Черитон просто преподаватель из университета в Стэнфорде. Несмотря на своё состояние он проживает скромную жизнь. А всё потому что в 1998 году одолжил 100 тыс. долларов 2 студентам на стартап под названием Google. Его текущий чистый капитал составляет 2.8 млрд. долларов.

Mapping Countries Manufacturing Output: China's Superpower vs. the World
In 2016, then-candidate Donald Trump said on the campaign trail, "My plan includes a pledge to restore manufacturing in the United States." Manufacturing has remained a major emphasis of Trump’s presidency, perhaps never more so than during the coronavirus pandemic, with the invoking of the Defense Production Act. So, what is the state of the U.S., and the global, manufacturing industry?

Visualizing the World’s Gold Demand
In times of market volatility, investors seek so-called “safe havens” like gold to limit exposure to losses. With financial markets seeing the most volatility in a decade as a result of the coronavirus, investors have indeed begun fleeing to gold, and gold prices posted their biggest weekly gain since 2008. This new demand has highlighted significant structural problems in the gold market, but few viable alternatives have been found.

• The U.S. currently pays $116M each year to the World Health Organization (WHO), or about 24% of the entire organization’s budget.
• China pays the second most of any country in the world at $57M, or 12% of the organization’s total.
• The vast majority of countries pay significantly less than the U.S. for the WHO. Only 13 countries pay more than $10M, including the U.S. and China.
• 44 countries pay less than $1M each year to support the WHO.
We took the data for our visual directly from a recent WHO report on annual funding totals for 2020. You can read more about how the WHO gets its money here. Focusing only on the countries with a total contribution of $100K or more, we changed the sizes and colors of countries on a world map corresponding to their contributions to the WHO, creating an intuitive snapshot of where the organization’s money comes from.

• The most expensive states for homeowners insurance tend to be located in Tornado Alley and along the Gulf Coast, led by Oklahoma with an average annual premium of $4,445, well over 60% higher than the national average.
• Hawaiians enjoy the cheapest rates for homeowners insurance at just $499 per year, thanks in large part to the relatively rare occurrences of insurable natural disasters.
• The Northeast and Northwest have below-average rates for insurance, including some states with major metro areas like New York, where it costs just $1,840.
• The national average is $2,305, but most people pay somewhere between $1,500 and $3,000 each year on homeowners insurance.
We found the data for our map at Insurance.com, a cost comparison website. There are a few assumptions behind the data in our map. Imagine a married couple with excellent credit wanted to insure a home worth $300,000 with typical policy features, like a $1,000 deductible and guest medical coverage of $5,000 per person. We calculated the avera

Visualizing Coronavirus Stimulus Programs Around the World
Just last year, the American economy was performing strong: the Dow Jones hit record highs and the U.S. unemployment hit a record 2.1%. In usual times, it would have been highly unlikely to have seen the country’s largest-ever stimulus package just a year later. But, the coronavirus has brought entirely unique circumstances to the world economy, and the U.S., along with other countries, has responded with massive economic programs.

Mapped: The Richest Women in the World
Last month, 2,095 individuals earned the honor of appearing on Forbes’ World Billionaires List. In some of our recent visualizations, we’ve used this list to map out the richest person in each country and in each state. But if you take a closer look, you’ll notice a pattern--most of them are men! But what about the richest women in the world? That’s the subject of our latest visualization, which illustrates where the world’s richest women in the world, how much they are worth, and in which industry they acquired their wealth.

Stacking up Liquidity: Is Bitcoin Playing in the Major League?
Bitcoin is enjoying a comeback, having topped $10,000 for several days in a row according to the crypto price tracker CryptoMarketCap. This got us thinking about its viability as a useful way to store and exchange value, and many investors would argue liquidity is the most important factor to consider.

Visualizing Bitcoin's Wild Ride in the Last Decade
In February 2011, Silk Road became the first online store to accept Bitcoin as payment. The new digital currency cost about one U.S. dollar per coin. The next decade would be a roller coaster for the digital currency, not limited to the FBI shutdown of Silk Road. What can we expect at the beginning of the second decade of Bitcoin exchange?

World Health Organization Funding in one Map: How Much Each Country Contributes
President Trump recently cut funding for the World Health Organization (WHO), claiming that the group didn’t do enough to protect Americans from the coronavirus. This made us wonder which countries make the biggest financial contributions to support the WHO.

This Chart Shows Over 100 Years of Gold and Silver Prices
A lot of investors are looking at the stock market and wondering how it could possibly be so high right now. Unemployment is at levels last seen in the Great Depression. The U.S. is facing historic civic unrest and protests. There’s an uncertain national election in 6 months. And a feared second wave of the coronavirus is still on the horizon. All these events are making people rethink their position on precious metals, and our latest visualization can provide a needed long-term perspective on financial history.


• The gold/silver spot ratio reached a record high of 132.4 in 1933 during the Great Depression.
• The same ratio collapsed to as low as 17.9 before President Nixon took the U.S. off the gold standard in 1971.
• The introduction of the American Eagle Gold and Silver Coins allowed investors to buy the precious metals directly, keeping the gold/silver ratio at elevated levels.
• The gold/silver ratio is approaching an all-time record high in the COVID economy, most recently topping out 91.5
Top 5 Highest Years for the Silver/Gold Spot Ratio
• 1941 - 101.4
• 1939 - 100
• 2020 - 99.3
• 1940 - 98.6
• 1990 - 93.2
Top 5 Lowest Years for Silver/Gold Spot Ratio
• 1967 - 15.4
• 1919 - 15.7
• 1862 - 16
• 1872 - 16.3
• 1874 - 16.6
The gold-to-silver spot ratio is a straightforward though relative measurement. It represents the number of silver ounces worth 1 ounce of gold. Since the prices of gold and silver can change, the spot ratio indicates the relative worth of these two metals. We grabbed the underlying data for our visualization from Gold Charts R Us in partnership with SD Bullion. Then, we combined the historical price information with a timeline of important events in the history of gold and silver from Reuters. The result is an intuitive snapshot of the history of gold and silver in U.S. history.
For the roughly 30 years after the American Civil War, gold and silver prices were stable relative to each other. By 1900 with the Gold Standard Act, the ratio had more than doubled from 16 to 34.5. The twentieth century then brought increasingly unstable gold/silver ratios, rising as high as 132.4 and forcing a 4-day banking holiday in 1933 during the Great Depression. Following World War II the ratio plummeted, eventually reaching a low of 17.9 in 1970. A year later, President Nixon ended the convertibility of U.S. dollars into gold.
Since Nixon ended the Gold Standard in 1971, the gold/silver spot ratio has been on an upward trajectory. In 1986, the U.S. Mint introduced the American Eagle Gold and Silver coins, allowing investors to buy the precious metals directly. Although it hasn’t reached its Great Depression record of 132.4, the most recent figure from May 2020 puts it at 91.5. This makes a lot of sense for a few different reasons. With unemployment rising to levels last seen in the Great Depression, and with the stock market defying gravity despite the unprecedented hit to the economy, gold and silver prices are responding to unclear economic realities like everything else. Investors might also be willing to place increasingly speculative bets, chasing yield out of boredom and as a substitute for the lack of sports. We don’t know what will happen to prices in the future, but there’s no doubt they will continue to change as the economy either hopefully improves or continues to deteriorate.

• Japan holds more U.S. debt than any other country in the world at $1,271.7B, or 18.67% of the total.
• China used to own the most debt but is now in second place at $1,081.6B or 15.88%.
• No other country besides Japan and China holds more than 6% of total foreign-held debt. The U.K. owns the third most in the world at just $395.3B or 5.8% of the total.
• Foreign countries control only about 30% of the entire national debt. American investors, the Federal Reserve and other parts of the U.S. government own the rest.
We collected the figures for our visualization from the U.S. Department of the Treasury as of March 2020, the latest month for complete numbers. We wanted to see which countries hold the most debt both in overall terms and a percentage of the whole. We also grouped countries from the same continents together. In turns out, there are two heavyweights in Japan and China, followed by dozens of other countries holding much smaller levels of U.S. debt.
Top Ten Foreign Holders of U.S. Debt
1. Japan: $1,271.7B
2. China: $1,081.6B
3. U.K.: $395.3B
4. Ireland: $271.5B
5. Brazil: $264.4B
6. Luxembourg: $246.1B
7. Hong Kong: $245.3B
8. Switzerland: $244.6B
9. Cayman Islands: $207.2B
10. Belgium: $206.1B
The most obvious takeaway is that Japan and China both account for the largest share of U.S. debt in our visual. According to the month-by-month figures from the Treasury, Japan surpassed China as the largest foreign holder of American debt in May 2019. Taken together, Japan and China account for $2,353.3B or 34.55% of American debt owned by foreign countries. In other words, two countries alone control more than a third of the foreign market for American debt.
But there are also a variety of other interesting nuggets about foreign holders of U.S. debt in our visualization. A number of European countries own a lot of debt, including the U.K. ($395.3B), Ireland ($271.5B) and Luxembourg ($246.1B). These countries don’t inspire the same kind of doom and gloom in the American media imagination as Japan and China. The Cayman Islands also deserve special mention because they own a surprising amount, $207.2B or 3.04% of all foreign holders. Perhaps that is due to American investors holding assets offshore but still looking for the security of government bonds.
Foreign holders of U.S. debt will have no shortage of opportunities to buy more of it. The U.S. national debt has been on an upward trajectory for several years. In fact, the recent coronavirus spending will up the deficit this year to $3.7T, pushing the national debt to new heights. There’s one big and important caveat to keep in mind when considering who owns the U.S. debt. The grand total amount of debt in our visualization only comes out to $6.8T. But smart observers know that the total U.S. debt is about $25.7T. What accounts for the difference? American investors, the Federal Reserve and other parts of the U.S. government actually own about 70% of the entire national debt. Foreign countries would need to buy trillions of more in U.S. debt before they’d control even half of the total.

Do you think that all the U.S. government’s spending will eventually come back to haunt the economy in the future? Let us know in the comments.

Charted: The Biggest Foreign Holders of U.S. Debt
The U.S. government is borrowing $3 trillion in the second quarter this year, an eye-popping number with unknown implications for the future of the economy. With so much government spending in response to the coronavirus, we started to wonder, which countries actually own the most U.S. debt?

How much sperm donors earn

The cost of one serving of semen is from 1500 to 3000 rubles. However, the full amount is not immediately paid, part immediately, and the rest after undergoing 6-month quarantine. Given the fact that a month can be donated up to 5-6 times, donation can generate income in the region of 10-15 thousand. This is up to about 200 thousand per year. But at the same time you need to lead a "chaste" lifestyle and abandon sex throughout the year. Abroad, one visit brings from 100 to 200 dollars.

The price of lunar minerals
