  “A smart, snappy guide to romance that dips into mathematical models. . . . illuminates age-old questions in brainy yet simple language.” —Washington Post 
   
  In this must-have for anyone who wants to better understand their love life, a mathematician pulls back the curtain and reveals the hidden patterns—from dating sites to divorce, sex to marriage—behind the rituals of love. 
   
  The roller coaster of romance is hard to quantify; defining how lovers might feel from a set of simple equations is impossible. But that doesn’t mean that mathematics isn’t a crucial tool for understanding love. 
   
  Love, like most things in life, is full of patterns. And mathematics is ultimately the study of patterns—from predicting the weather to the fluctuations of the stock market, the movement of planets or the growth of cities. These patterns twist and turn and warp and evolve just as the rituals of love do. 
   
  In The Mathematics of Love, Dr. Hannah Fry takes the reader on a fascinating journey through the patterns that define our love lives, applying mathematical formulas to the most common yet complex questions pertaining to love: What’s the chance of finding love? What’s the probability that it will last? How do online dating algorithms work, exactly? Can game theory help us decide who to approach in a bar? At what point in your dating life should you settle down? 
   
  From evaluating the best strategies for online dating to defining the nebulous concept of beauty, Dr. Fry proves—with great insight, wit, and fun—that math is a surprisingly useful tool to negotiate the complicated, often baffling, sometimes infuriating, always interesting, mysteries of love.

  “An excellent introduction to the challenges and opportunities of agricultural life in a difficult region for farming . . . elegantly written.” —Jeff Bremer, The Annals of Iowa 
   
  Prairie busting is central to the lore of westward expansion, but how was it actually accomplished with little more than animal and human power? In Sod Busting, David B. Danbom challenges students to think about the many practicalities of surviving on the Great Plains in the late nineteenth century by providing a detailed account of how settlers acquired land and made homes, farms, and communities. He examines the physical and climatic obstacles of the plains—perhaps America’s most inhospitable frontier—and shows how settlers sheltered themselves, gained access to fuel and water, and broke the land for agriculture. 
   
  Treating the Great Plains as a post-industrial frontier, Danbom delves into the economic motivations of settlers, how they got the capital they needed to succeed, and how they used the labor of the entire family to survive until farms returned profits. He examines closely the business decisions that determined the success or failure of these farmers in a boom-and-bust economy; details the creation of churches, schools, and service centers that enriched the social and material lives of the settlers; and shows how the support of government, railroads, and other businesses contributed to the success of plains settlement. 
   
  Based on contemporary accounts, settlers’ reminiscences, and the work of other historians, Sod Busting dives deeply into the practical realities of how things worked to make vivid one of the quintessentially American experiences, breaking new land. 
   
  “A cogent and engaging portrait of the real lives of those who settled the Great Plains.” —Nebraska History

  No Apparent Danger - The True...

  On January 14, 1993, a team of scientists descended into the crater of Galeras, a restless Andean volcano in southern Colombia, for a day of field research. As the group slowly moved across the rocky moonscape of the caldera near the heart of the volcano, Galeras erupted, its crater exploding in a barrage of burning rocks and glowing shrapnel. Nine men died instantly, their bodies torn apart by the blast.While others watched helplessly from the rim, Colombian geologist Marta Calvache raced into the rumbling crater, praying to find survivors. This was Calvache's second volcanic disaster in less than a decade. In 1985 Calvache was part of a group of Colombia's brightest young scientists that had been studying activity at Nevado del Ruiz, a volcano three hundred miles north of Galeras. They had warned of the dire consequences of an eruption for months, but their fledgling coalition lacked the resources and muscle to implement a plan of action or sway public opinion. When Nevado del Ruiz erupted suddenly in November 1985, it wiped the city of Armero off the face of the earth and killed more than twenty-three thousand people -- one of the worst natural disasters of the twentieth century.No Apparent Danger links the characters and events of these two eruptions to tell a riveting story of scientific tragedy and human heroism. In the aftermath of Nevado del Ruiz, volcanologists from all over the world came to Galeras -- some to ensure that such horrors would never be repeated, some to conduct cutting-edge research, and some for personal gain. Seismologists, gas chemists, geologists, and geophysicists hoped to combine their separate areas of expertise to better understand and predict the behavior of monumental forces at work deep within the earth.And yet, despite such expertise, experience, and training, crucial data were ignored or overlooked, essential safety precautions were bypassed, and fifteen people descended into a death trap at Galeras. Incredibly, expedition leader Stanley Williams was one of five who survived, aided bravely by Marta Calvache and her colleagues. But nine others were not so lucky.Expertly detailing the turbulent history of Colombia and the geology of its snow-peaked volcanoes, Victoria Bruce weaves together the stories of the heroes, victims, survivors, and bystanders, evoking with great sensitivity what it means to live in the shadow of a volcano, a hair's-breadth away from unthinkable natural calamity, and shows how clashing cultures and scientific arrogance resulted in tragic and unnecessary loss of life.

  In old times, number theory was also known as arithmetic. However, now arithmetic and number theory are considered as separate branches from each other’s, it was not same in old times. Number theory is one of the many important branches of pure mathematics. This branch is mainly dedicated and includes study about integers. This theory describes many fundamental and basic concepts of mathematics that were used to develop modern concepts. Thus, number theory is often referred as “Queen of Mathematics”. In number theory, following concepts are described:Concept of prime numbersProperties of objects that are derived through integersGeneralization of integers 
  Rational numbers and algebraic integers are significant concepts that are included in number theory. In number theory, integers are considered as a solution to a particular problem. This concept is known as Riemann Zeta Function. However, it is not necessary to consider them as solution only; they can also be considered in themselves. Study of analytical objects helps to understand questions in number theory. Properties of integers, prime numbers and number-theoretic objects are described in Riemann Zeta Function. These properties can be studied descriptively in a separated branch named analytic number theory. In Diophantine approximation, real numbers are learnt in ration to relational number. 
  In older terms, arithmetic was used to refer number theory. However, it was separated in early 20th century. Arithmetic word is now used to refer to general elementary calculations. Term arithmetic is now used in many fields such as:Mathematical logicPeano arithmeticComputer scienceFloating point arithmetic 
  In late 20th century, French theorists leaved a noticeable impact on number theory. Due to their influence, they again related tern arithmetic with number theory. However, many theorists argued upon this and denied to accept this as it was already proven false in past time. However, term arithmetical is now considered as adjective to number-theoretic. Early 20th century was a golden time for development of number theory, especially the time span of 1930s and 1940s. Many important results were acquired in that period. Later on, 1970s was proven an important period as well with the development of computational complexity theory. 
  Number theory is an important branch of pure mathematics since it contains many basic concepts that are used to build up complex concepts of pure mathematics. One who is looking for a breakthrough in broad term mathematics is suggested to start from this theory. It will clear up basic concepts so it will be surprisingly easy to understand complex concepts. This short book describes all the basic concepts without going in too deep. So, one can use this basic knowledge to understand complex concepts easily and effectively.
