Rutherford and Fry’s Complete Guide to Absolutely Everything

The presenters of BBC Radio 4's flagship show, The Curious Cases of Rutherford and Fry, set about explaining life's great mysteries.

Brought to you by Penguin. 
 
'If only Adam Rutherford and Hannah Fry were on tap to all of us, all the time . . . The pair have such a gift for making life, numbers and the forces at work in the universe all the richer, stranger, funnier and more marvellous.' Stephen Fry 
 
In Rutherford and Fry's comprehensive guidebook, they tell the complete story of the universe and absolutely everything in it - skipping over some of the boring parts. 
This is a celebration of the weirdness of the cosmos, the strangeness of humans and the fact that amid all the mess, we can somehow make sense of life. 
 
Our brains have evolved to tell us all sorts of things that feel intuitively right but just aren't true: the world looks flat, the stars seem fixed in the heavenly firmament, a day is 24 hours... This book is crammed full of tales of how stuff really works. With the power of science, Rutherford and Fry show us how to bypass our monkey-brains, taking us on a journey from the origin of time and space, via planets, galaxies, evolution, the dinosaurs, all the way into our minds, and wrestling with some truly head-scratching questions that only science can answer: 
 
What is time, and where does it come from? 
Why are animals the size and shape they are? 
How horoscopes work (Spoiler: they don't, but you think they do) 
Does my dog love me? 
Why nothing is truly round? 
Do you need your eyes to see? 
 
'A wonderfully engaging blend of wit, enthusiasm, clarity and knowledge.' Bill Bryson 
'Like the universe itself, this book is multi-faceted, surprising and full of wonders. It's also funny, wise and exceedingly brainy. You really owe it to yourself to read it.' Tim Harford, author of How To Make The World Add Up

How to be Human in the Age of the Machine

Hello World

Would you let an algorithm determine your fate? Hannah Fry lifts the lid on the world of algorithms, examining how they impact our future and whether they really are an improvement on the humans they replace.

A stylish, thoughtful, and scrupulously fair-minded account of what the software that increasingly governs our lives can and cannot do ... A beautifully accessible guide that leaps lightly from one story to the next without sparing the reader hard questions... deserves a place in the bestseller charts.

With refreshing simplicity, Fry explains what AI, machine learning and complicated algorithms really mean, providing some succinct explanations of the Cambridge Analytica scandal, driverless cars and many other unnerving modern phenomena…This book illustrates why good science writers are essential.

Brilliantly clear...Fry succinctly outlines the ethical issues that beset AI

Hello World is a gem of accessible science writing.

____________ 
 
How do you apply game theory to select who should be on your Christmas shopping list ? Can you predict Her Majesty's Christmas Message? Will calculations show Santa is getting steadily thinner - shimmying up and down chimneys for a whole night - or fatter - as he tucks into a mince pie and a glass of sherry in billions of houses across the world? 
 
Full of diagrams, sketches and graphs, beautiful equations, Markov chains and matrices, The Indisputable Existence of Santa Claus brightens up the bleak midwinter with stockingfuls of mathematical marvels. And proves once and for all that maths isn't just for old men with white hair and beards who associate with elves. 
 
Maths has never been merrier.
