“‘The greatest and most endangered species in the Amazon rainforest is not the jaguar or the harpy eagle,’ says Mark Plotkin, ‘It’s the isolated and uncontacted tribes.’ In an energetic and sobering talk, the ethnobotanist brings us into the world of the forest’s indigenous tribes and the incredible medicinal plants that their shamans use to heal. He outlines the challenges and perils that are endangering them — and their wisdom — and urges us to protect this irreplaceable repository of knowledge.”
“One of the most popular projections is the Mercator, but of course, it too has its flaws. In truth, Africa is 14 times larger than Greenland, Canada is only 1.2 times the size of the United States, and Antarctica is definitely not the colossal continent it is portrayed to be.
“However, don’t get the idea that the Mercator is a bad map. It’s not. The map preserves “true compass bearings between any two points” and has become a standard in nautical navigation.
“Since there is no perfect map for all occasions, your best bet is to pinpoint what you need a map for and then to weigh the advantages and disadvantages of each to suit your goal.”

Fresh and Slick Rick’s 1984 hit that has been reimagined for every generation since.”
“The world turns on symmetry — from the spin of subatomic particles to the dizzying beauty of an arabesque. But there’s more to it than meets the eye. Here, Oxford mathematician Marcus du Sautoy offers a glimpse of the invisible numbers that marry all symmetrical objects.”
‘I am a mathematician, and I would like to stand on your roof.’ That is how Ron Eglash greeted many African families he met while researching the fractal patterns he’d noticed in villages across the continent.”
“‘People are so afraid of variety that they try to fit everything into a tiny little box with a specific label,’ says 16-year-old Rosie King, who is bold, brash and autistic. She wants to know: Why is everyone so worried about being normal? She sounds a clarion call for every kid, parent, teacher and person to celebrate uniqueness.
