Exploring and explaining a litany of glitches, near misses, and mathematical mishaps involving the internet, big data, elections, street signs, lotteries, the Roman Empire, and an Olympic team, Matt Parker uncovers the bizarre ways math trips us up, and what this reveals about its essential place in our world.

Mark Lynas delivers a vital account of the future of our earth, and our civilisation, if current rates of global warming persist. And it’s only looking worse. We are living in a climate emergency. But how much worse could it get? Will civilisation collapse? Are we already past the point of no return? What kind of future can our children expect? Rigorously cataloguing the very latest climate science, Mark Lynas explores the course we have set for Earth over the next century and beyond.

If this is true of the man who founded the One Day's Wages global antipoverty movement, then what must it take to act on one's ideals? Cho does not doubt the sincerity of those who want to change the world.

For more than 30 years, humankind has known how to grow enough food to end chronic hunger worldwide. Yet while the Green Revolution succeeded in South America and Asia, it never got to Africa. More than 9 million people every year die of hunger, malnutrition, and related diseases every yearmost of them in Africa and most of them children. More die of hunger in Africa than from AIDS and malaria combined. Now, an impending global food crisis threatens to make things worse.
