Up till now, Sky’s contribution to the nature documentary has generally been in the 3D sphere and with David Attenborough. But they can do standard natural history, too, and this two-part look at the rise of the big cat is perfect viewing. Biologist Patrick Aryee (you might remember him from the BBC Super Senses series) criss-crosses the globe for close personal contact with playful cloud leopard juveniles in Thailand, and a slightly less friendly encounter with a lion in South Africa. You can’t help but be impressed by feline resourcefulness, be it the extra fat stored on the belly of Siberian tigers to keep the chill of deep snow at bay, or the powerful back legs of the delicate African caracal that allow it to leap three metres in the air to catch birds in flight. All lovingly captured, with plenty of slo-mo for detail.

Calculus offers some of the most astounding advances in all of mathematics—reaching far beyond the two-dimensional applications learned in first-year calculus. We do not live on a sheet of paper, and in order to understand and solve rich, real-world problems of more than one variable, we need multivariable calculus, where the full depth and power of calculus is revealed.
