    Tie Knots unravels the history of ties, the story of the discovery of the new knots and some very elegant mathematics in action. If Einstein had been left alone in Tie Rack for long enough perhaps he would have worked it out : why do people tie their ties in only 4 ways? And how many other possibilities are there? Two Cambridge University physicists, research fellows working from the Cavendish laboratories, have discovered via a recherche branch of mathematics - knot theory - that although only four knots are traditionally used in tying neck ties another 81 exist. This is the story of their discovery, of the history of neck ties and of the equations that express whether a tie is handsome or not. Of the 81 new knots, 6 are practical and elegant. We now have somewhere else to go after the Pratt, the Four-in-Hand, the Full and Half Windsor. Sartorial stylishness is wrapped effortlessly around popular mathematics. A concept developed to describe the movement of gas molecules - the notion of persistent walks around a triangular lattice - also describes the options for tie tying. Pure maths becomes pure fashion in a delightfully designed little package from Fourth Estate.

    The true story of Wrong Way Humphrey

    When she finds it, she lays her eggs on the plant, so when each egg hatches, the baby caterpillar can feed on the milkweed leaves. The milkweed plant then provides the perfect protection as the caterpillar turns into one of nature's wonders, a chrysalis, before transforming into an even greater wonder: a monarch butterfly. And once the newborn butterfly soars away, the milkweed seeds fly away on the wind and start this cycle over again. The exacting prose and jewel-toned illustrations echo the harmony of monarch and milkweed in this carefully researched book, explaining one of nature's most spectacular displays in a refreshingly simple manner.
