    Author: SPIEGELHALTER DAVID


    'This marvellous book will transform your relationship with the numbers that swirl all around us. Read it and learn. I did' Tim Harford


    Statistics has played a leading role in our scientific understanding of the world for centuries, yet we are all familiar with the way statistical claims can be sensationalised, particularly in the media. In the age of big data, as data science becomes established as a discipline, a basic grasp of statistical literacy is more important than ever.


    In The Art of Statistics, David Spiegelhalter guides the reader through the essential principles we need in order to derive knowledge from data. Drawing on real world problems to introduce conceptual issues, he shows us how statistics can help us determine the luckiest passenger on the Titanic, whether serial killer Harold Shipman could have been caught earlier, and if screening for ovarian cancer is beneficial.


    How many trees are there on the planet? Do busier hospitals have higher survival rates? Why do old men have big ears? Spiegelhalter reveals the answers to these and many other questions - questions that can only be addressed using statistical science.

    Title: Lying Numbers
    Author: BARKER HUGH


    A readily understandable exploration of how figures are badly reported or deliberately misrepresented everywhere from political arguments and briefings to business presentations and shopping offers.

    Praise for Hugh Barker's Million Dollar Maths:

    'Great fun. A clear, original and highly readable account of the curious relationship between mathematics and money.' Professor Ian Stewart - author of Significant Figures

    'A lively crash course in the mathematics of gambling, investing, and managing. Hugh Barker makes deep ideas fun and profitable.' William Poundstone - author of How to Predict the Unpredictable

    Politicians, economists, scientists, journalists . . . all of them have been known to bend the truth and to twist the facts from time to time. But surely the numbers and statistics they rely on are cold, hard objective facts that tell the real story?

    Of course the truth is much murkier than that. Figures can be misinterpreted, misunderstood, misconstrued and misused in hundreds of different ways. This book takes a look at the many ways that statistical information can be badly reported or deliberately misused in all walks of life, from political arguments, to business presentations, to more local concerns such as shopping offers and utility bills.

    A polemical guide to how numbers are used to mislead, which is intended to help the reader through the minefield of dubious stats and lying numbers.

    Title: Math with Bad Drawings: Ideas + Stick Figures = Enlightenment
    Author: ORLIN BEN


    In MATH WITH BAD DRAWINGS, Ben Orlin answers math's three big questions: Why do I need to learn this? When am I ever going to use it? Why is it so hard? The answers come in various forms-cartoons, drawings, jokes, and the stories and insights of an empathetic teacher who believes that math should belong to everyone.


    Eschewing the tired old curriculum that begins in the wading pool of addition and subtraction and progresses to the shark infested waters of calculus (AKA the Great Weed Out Course), Orlin instead shows us how to think like a mathematician by teaching us a new game of Tic-Tac-Toe, how to understand an economic crisis by rolling a pair of dice, and the mathematical reason why you should never buy a second lottery ticket.


    Every example in the book is illustrated with his trademark "bad drawings," which convey both his humor and his message with perfect pitch and clarity. Organized by unconventional but compelling topics such as "Statistics: The Fine Art of Honest Lying," "Design: The Geometry of Stuff That Works," and "Probability: The Mathematics of Maybe," MATH WITH BAD DRAWINGS is a perfect read for fans of illustrated popular science.

    Title: Mathematics for Human Flourishing
    Author: SU FRANCIS; JACKSON CHRISTOPHER (CONTRIBUTION BY)

    Winner of the Mathematics Association of America's 2021 Euler Book Prize, this is an inclusive vision of mathematics--its beauty, its humanity, and its power to build virtues that help us all flourish

    "This is perhaps the most important mathematics book of our time. Francis Su shows mathematics is an experience of the mind and, most important, of the heart."--James Tanton, Global Math Project
    &
    "A good book is an entertaining read. A great book holds up a mirror that allows us to more clearly see ourselves and the world we live in. Francis Su's Mathematics for Human Flourishing is both a good book and a great book."--MAA Reviews

    For mathematician Francis Su, a society without mathematical affection is like a city without concerts, parks, or museums. To miss out on mathematics is to live without experiencing some of humanity's most beautiful ideas.
    &
    In this profound book, written for a wide audience but especially for those disenchanted by their past experiences, an award+'winning mathematician and educator weaves parables, puzzles, and personal reflections to show how mathematics meets basic human desires--such as for play, beauty, freedom, justice, and love--and cultivates virtues essential for human flourishing. These desires and virtues, and the stories told here, reveal how mathematics is intimately tied to being human. Some lessons emerge from those who have struggled, including philosopher Simone Weil, whose own mathematical contributions were overshadowed by her brother's, and Christopher Jackson, who discovered mathematics as an inmate in a federal prison. Christopher's letters to the author appear throughout the book and show how this intellectual pursuit can--and must--be open to all.

    Author: OAKLEY BARBARA

    Whether you are a student struggling to fulfill a math or science requirement, or you are embarking on a career change that requires a higher level of math competency, A Mind for Numbers offers the tools you need to get a better grasp of that intimidating but inescapable field. Engineering professor Barbara Oakley knows firsthand how it feels to struggle with math. She flunked her way through high school math and science courses, before enlisting in the army immediately after graduation. When she saw how her lack of mathematical and technical savvy severely limited her options--both to rise in the military and to explore other careers--she returned to school with a newfound determination to re-tool her brain to master the very subjects that had given her so much trouble throughout her entire life.& In A Mind for Numbers, Dr. Oakley lets us in on the secrets to effectively learning math and science--secrets that even dedicated and successful students wish they''d known earlier. Contrary to popular belief, math requires creative, as well as analytical, thinking. Most people think that there''s only one way to do a problem, when in actuality, there are often a number of different solutions--you just need the creativity to see them. for example, there are more than three hundred different known proofs of the Pythagorean Theorem. In short, studying a problem in a laser-focused way until you reach a solution is not an effective way to learn math. Rather, it involves taking the time to step away from a problem and allow the more relaxed and creative part of the brain to take over. A Mind for Numbers shows us that we all have what it takes to excel in math, and learning it is not as painful as some might think!''A good teacher will leave you educated. But a great teacher will leave you curious. Well, Barbara Oakley is a great teacher. Not only does she have a mind for numbers, she has a way with words, and she makes every one of them count.'' Mike Rowe, creator and host of Discovery Channel''s ''Dirty Jobs'' and CEO of mikeroweWORKS''If you struggled through math and slept through science, there''s hope.

    Title: Number Bias: How Numbers Lead & Mislead Us
    Author: BLAUW SANNE

    'The Number Bias combines vivid storytelling with authoritative analysis to deliver a warning about the way numbers can lead us astray - if we let them.' TIM HARFORD

    Even if you don't consider yourself a numbers person, you are a numbers person. The time has come to put numbers in their place. Not high up on a pedestal, or out on the curb, but right where they belong: beside words.

    It is not an overstatement to say that numbers dictate the way we live our lives. They tell us how we're doing at school, how much we weigh, who might win an election and whether the economy is booming. But numbers aren't as objective as they may seem; behind every number is a story. Yet politicians, businesses and the media often forget this - or use it for their own gain.

    Sanne Blauw travels the world to unpick our relationship with numbers and demystify our misguided allegiance, from Florence Nightingale using statistics to petition for better conditions during the Crimean War to the manipulation of numbers by the American tobacco industry and the ambiguous figures peddled during the EU referendum.

    Taking us from the everyday numbers that govern our health and wellbeing to the statistics used to wield enormous power and influence, The Number Bias counsels us to think more wisely.

    "Unreasonably entertaining....reveals how geometric thinking can allow for everything from fairer American elections to better pandemic planning." - The New York Times& &

    From the New York Times-bestselling author of How Not to Be Wrong--himself a world-class geometer--a far-ranging exploration of the power of geometry, which turns out to help us think better about practically everything.


    How should a democracy choose its representatives? How can you stop a pandemic from sweeping the world? How do computers learn to play Go, and why is learning Go so much easier for them than learning to read a sentence? Can ancient Greek proportions predict the stock market? (Sorry, no.) What should your kids learn in school if they really want to learn to think? All these are questions about geometry. For real.

    If you're like most people, geometry is a sterile and dimly remembered exercise you gladly left behind in the dust of ninth grade, along with your braces and active romantic interest in pop singers. If you recall any of it, it's plodding through a series of miniscule steps only to prove some fact about triangles that was obvious to you in the first place. That's not geometry. Okay, it is geometry, but only a tiny part, which has as much to do with geometry in all its flush modern richness as conjugating a verb has to do with a great novel.

    Shape reveals the geometry underneath some of the most important scientific, political, and philosophical problems we face. Geometry asks: Where are things? Which things are near each other? How can you get from one thing to another thing? Those are important questions. The word "geometry," from the Greek for "measuring the world." If anything, that's an undersell. Geometry doesn't just measure the world--it explains it. Shape shows us how.

The answers to all these questions can be found in geometry.

    'A superbly written, riveting book.' Martin Rees

    Searching for the fundamental laws of the universe, physicists have found themselves developing ambitious mathematical ideas. But without observation and experiment as their guide, are they now doing 'fairy-tale physics' as their detractors claim?


    In The Universe Speaks in Numbers, Graham Farmelo argues that today's greatest scientific minds are working in a tradition that dates back to Newton. He takes us on an adventure, from the Enlightenment to the breakthroughs of Einstein and Dirac, to the work of modern physicists and mathematicians shedding light on each other's disciplines, to their mutual surprise and excitement. This blossoming relationship is responsible for huge advances in our understanding of space and time - and as Farmelo explains, could redefine reality as we know it.
