    Pure mathematics, the area of Bourbaki's work, seems on the surface to be an abstract field of human study with no direct connection with the real world. In reality, however, it is closely intertwined with the general culture that surrounds it. Major developments in mathematics have often followed important trends in popular culture; developments in mathematics have acted as harbingers of change in the surrounding human culture. The seeds of change, the beginnings of the revolution that swept the Western world in the early decades of the twentieth century — both in mathematics and in other areas — were sown late in the previous century. This is the story both of Bourbaki and the world that created him in that time. It is the story of an elaborate intellectual joke — because Bourbaki, one of the foremost mathematicians of his day — never existed.

    Putting people into places and situations unprecedented in history is stirred the imagination while the human experience was expanding and redefining. Yet, space exploration compels humans to confront a hostile environment of cosmic radiations, radical changes in the gravity and magnetic fields, as well as social isolation. Therefore, any space traveller is submitted to relevant health-related threats. In the twenty-first century, human space flight is poised to continue, but it will enjoy the ongoing developments in science and technology. It will become more networked, more global, and more oriented toward primary goals. A novel international human space flight policy could help achieve these objectives by clarifying the rationale, the ethics of acceptable risk, the role of remote presence, and the need for balance between funding and ambition to justify the risk of human lives. In order to address such a challenge, a preliminary careful survey of the available scientific data is mandatory to set forth adequate countermeasures. Envisaged solutions should provide a sound and technically feasible approach for counteracting microgravity and cosmic rays effects, which represent the main health risk for space crews. This objective must necessarily be sustained by national/international space agencies, which would coordinate their common efforts into a defined international spaceflight program.

    When hearing those words just a couple of years back, people used to say: It’s a scam, financial bubble IThere is no point in investing, the price is too low INo country will ever recognize cryptocurrency IIt’s an obvious pyramid scheme IIt’s a sort of amusement for nerds IIt's not serious, it will collapse in a couple of years. Until recently, cryptocurrency had been viewed as a sort of amusement for a handful of the chosen who bought and sold something and believed that a new currency would make a hit one day! You surely were also among those people who did not take Bitcoin and cryptocurrency seriously, but the current events gag even the biggest skeptics. Current Bitcoin price is 6,644$* The price of the most popular cryptocurrency repeatedly breaks all the unthinkable records. Capitalization is about $120 billion World recognition The world's largest economies – India and Japan – recognized Bitcoin as the official currency. The US authorities recognized cryptocurrency as the asset. And this is just the beginning. Mining on an industrial scale The cryptocurrency market is extremely fast-changing, and it is almost impossible to monitor the situation and make the right decisions on your own. Most people have no proper experience, time and money for that. My book gives basic yet quite extensive information for those people who do not chase a rainbow but want to build a long-term profitable business in one of the cryptocurrency areas: from mining to investing. So, this book is not about: Illegal ways of making money Praising cryptocurrency and urging you to invest in it to the last penny Fraud techniques and making a fast buck Boring and pointless theory Ways to earn millions without investments and risks This book will help you get to learn the following: Which way of making money in cryptocurrency market suits you best. Where should you start if you have just $500. What information about cryptocurrency the experts withhold (Take the rose-colored glasses off!). How to elaborate a personal strategy, set up your own cryptocurrency business and earn your first $3,000-10,000 as early as 2018. I can also guarantee that you: Puzzle out the main present-day currency trend even if you are clueless about economics, finance and technology. Understand whether you really want to invest in cryptocurrency (perhaps, this type of business doesn’t suit you at all and you will save your time) Get to learn how to check the risks and not to invest in the first available currency Having considered my experience, protect yourself from possible failures and pouring money down the drain which will inevitably happen if you go it blind.

    Now that its basketball program has fallen apart, CSU’s only claim to fame is its Gravinics Department, dedicated to the study of an obscure European country—its mythology, its extraordinarily difficult language, and especially its bizarre star poet, Henderson.Having discovered Henderson’s poetry in a trash bin, Stanley Higgs becomes the foremost scholar of the poet’s work, accepts a position at Chandler State University, achieves international academic fame, marries the Dean’s daughter, and abruptly stops talking. With all of academia convinced that Higgs is formulating a great truth, the university employs Orwellian techniques to record Higgs’s every potential utterance and to save its reputation. A feckless Gravinics language student, Samuel Grapearbor, together with his long-suffering girlfriend Julia, is hired to monitor Higgs during the day. Over endless games of checkers and shared sandwiches, a uniquely silent friendship develops. As one man struggles to grow up and the other grows old, The Grasshopper King, in all of his glory, emerges.In this debut novel about treachery, death, academia, marriage, mythology, history, and truly horrible poetry, Jordan Ellenberg creates a world complete with its own geography, obscene folklore, and absurdly endearing -characters—a world where arcane subjects flourish and the smallest swerve from convention can result in -immortality.Jordan Ellenberg was born in Potomac, Maryland in 1971. His brilliance as a mathematical prodigy led to a feature in The National Enquirer, an interview with Charlie Rose on CBS’s Nightwatch, and gold medals at the Math Olympiad in Cuba and Germany. He is now an Assistant Professor of Math at Princeton University and his column, "Do the Math," appears regularly in the online journal Slate. This is his first novel.

    No, hang on, let's make this interesting. Between zero and infinity. Even if you stick to the whole numbers, there are a lot to choose from - an infinite number in fact. Throw in decimal fractions and infinity suddenly gets an awful lot bigger (is that even possible?) And then there are the negative numbers, the imaginary numbers, the irrational numbers like pi which never end. It literally never ends.The world of numbers is indeed strange and beautiful. Among its inhabitants are some really notable characters - pi, e, the "imaginary" number i and the famous golden ratio to name just a few. Prime numbers occupy a special status. Zero is very odd indeed: is it a number, or isn't it?How Numbers Work takes a tour of this mind-blowing but beautiful realm of numbers and the mathematical rules that connect them. Not only that, but take a crash course on the biggest unsolved problems that keep mathematicians up at night, find out about the strange and unexpected ways mathematics influences our everyday lives, and discover the incredible connection between numbers and reality itself.
