Following closely behind is y, or gamma, a constant that arises in many mathematical areas yet maintains a profound sense of mystery. In a tantalizing blend of history and mathematics, Julian Havil takes the reader on a journey through logarithms and the harmonic series, the two defining elements of gamma, toward the first account of gamma's place in mathematics. Introduced by the Swiss mathematician Leonhard Euler (1707-1783), who figures prominently in this book, gamma is defined as the limit of the sum of 1 + 1/2 + 1/3 + . . . Up to 1/n, minus the natural logarithm of n--the numerical value being 0.5772156. . . . But unlike its more celebrated colleagues π and e, the exact nature of gamma remains a mystery--we don't even know if gamma can be expressed as a fraction. Among the numerous topics that arise during this historical odyssey into fundamental mathematical ideas are the Prime Number Theorem and the most important open problem in mathematics today--the Riemann Hypothesis (though no proof of either is offered!). Sure to be popular with not only students and instructors but all math aficionados, Gamma takes us through countries, centuries, lives, and works, unfolding along the way the stories of some remarkable mathematics from some remarkable mathematicians.-- "Notices of the American Mathematical Society"

    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.

    It is a bridge from the computational courses (such as calculus or differential equations) that students typically encounter in their first year of college to a more abstract outlook. It lays a foundation for more theoretical courses such as topology, analysis and abstract algebra. Although it may be more meaningful to the student who has had some calculus, there is really no prerequisite other than a measure of mathematical maturity. Topics include sets, logic, counting, methods of conditional and non-conditional proof, disproof, induction, relations, functions and infinite cardinality.

    Beautifully illustrated with old engravings as well as contemporary imagery, Sacred Number introduces basic counting systems; significant numbers from major religious texts; the importance of astronomy, geometry, and music to number quality; how numbers affect architecture. Lundy explains why the ideas of Pythagoras still resonate, and she profiles each number from one to ten to show its distinct qualities: why, for example, the golden section is associated with five, and seven with the Virgin Mary.
