0.999...
–
In mathematics, the repeating decimal 0. 999… denotes a real number that can be shown to be the number one. In other words, the symbols 0. 999… and 1 represent the same number, more generally, every nonzero terminating decimal has an equal twin representation with infinitely many trailing 9s. The terminating decimal representation is preferred, contributing to the misconception that it is the only representation. The same phenomenon occurs in all other bases or in any representation of the real numbers. The equality of 0. 999… and 1 is closely related to the absence of nonzero infinitesimals in the number system. Some alternative number systems, such as the hyperreals, do contain nonzero infinitesimals, the equality 0. 999… =1 has long been accepted by mathematicians and is part of general mathematical education. Nonetheless, some find it sufficiently counterintuitive that they question or reject it. Such skepticism is common enough that the difficulty of convincing them of the validity of this identity has been the subject of studies in mathematics education. Algebraic proofs showing that 0. 999… represents the number 1 use concepts such as fractions, long division, however, these proofs are not rigorous as they do not include a careful analytic definition of 0. 999…. One reason that infinite decimals are an extension of finite decimals is to represent fractions. Using long division, a division of integers like 1⁄9 becomes a recurring decimal,0. 111…. This decimal yields a quick proof for 0. 999… =1, If 0. 999… is to be consistent, it must equal 9⁄9 =1. 0.333 … =390.888 … =890.999 … =99 =1 When a number in decimal notation is multiplied by 10, the digits do not change but each digit moves one place to the left. Thus 10 ×0. 999… equals 9. 999…, which is 9 greater than the original number, in introductory arithmetic, such proofs help explain why 0. 999… =1 but 0. 333… <0.34. In introductory algebra, the proofs help explain why the method of converting between fractions and repeating decimals works. Once a representation scheme is defined, it can be used to justify the rules of decimal arithmetic used in the above proofs. Moreover, one can demonstrate that the decimals 0. 999… and 1. 000… both represent the same real number, it is built into the definition. Since the question of 0. 999… does not affect the development of mathematics

We are the 99%
–
We are the 99% is a political slogan widely used and coined by the Occupy movement. It was the name of a Tumblr blog page launched in late August 2011 and is a variation on the phrase We The 99% from an August 2011 flyer for the NYC General Assembly. A related statistic, the 1%, refers to the top 1% wealthiest people in society that have a share of capital, political influence. The phrase directly refers to the income and wealth inequality in the United States with a concentration of wealth among the top earning 1% and it reflects an opinion that the 99% are paying the price for the mistakes of a tiny minority within the upper class. As of 2009, all households with less than $343,927 belonged to the lower 99% of the United States income distribution. The concept has been criticized as being an old. The slogan has also used in other countries, not just the US. Beginning in 2015, the statistic of the 1% was used often in Bernie Sanderss presidential campaign. Chris credited an August 2011 flyer for the NYC assembly We The 99% for the term, a 2011 Rolling Stone article attributed to anthropologist David Graeber the suggestion that the Occupy movement represented the 99%. In the article Stiglitz spoke of the impact of economic inequality involving 1% of the U. S. Throughout history, this is something that the top 1% eventually do learn and we are the 99% is a political slogan and an implicit economic claim of Occupy protesters. It refers to the concentration of income and wealth since the 1970s among the top 1% of income earners in the United States. It also reflects an opinion that the 99% are paying the price for the mistakes of a minority within the upper class. Between 1979 and 2007, the top earning 1 percent of Americans have seen their after-tax-and-benefit incomes grow by an average of 275%, compared to around 40-60% for the lower 99 percent. Since 1979 the average income for the bottom 90% of households has decreased by $900. This imbalance became further exacerbated by changes making federal income taxes less progressive, from 1992-2007 the top 400 income earners in the U. S. saw their income increase 392% and their average tax rate reduced by 37%. In 2009, the income of the top 1% was $960,000 with a minimum income of $343,927. In 2007 the top 1% had a share of total income than at any time since 1928

Grave Dancers Union
–
Grave Dancers Union is the sixth studio album by the American alternative rock band Soul Asylum, released in 1992. The album spent 76 weeks on the Billboard music charts and was certified triple-platinum in 1993, during recording of Grave Dancers Union, producer Michael Beinhorn grew dissatisfied with drummer Grant Youngs performance and brought in Sterling Campbell. It was the beginning of the end of Youngs tenure in the band and he and Campbell would each wind up playing on about half the record. Campbell was eventually named the official drummer. The Runaway Train single, released in June 1993, reached five on the Billboard Hot 100. Though the album had sold well to that point, the breakout success of that single was a major factor in the albums eventual multi-platinum sales figures. The cover illustration is by Czech erotic art photographer Jan Saudek, the albums title comes from the line I tried to dance at a funeral, New Orleans style, I joined the Grave Dancers Union, I had to file, from the song Without a Trace.
