When a tortoise challenges a great Greek hero to use his logic in order to decipher a simple philosophical argument, slight chaos ensues. ‘What the Tortoise Said to Achilles’ is an endless cycle of suppositions and deductions. A refined piece of philosophical writing, Caroll’s discussion was one of the first steps towards paradoxically explaining logical truth. His clever prose makes this novel an essential read for budding philosophers and logic aficionados. Lewis Caroll (1832-1898) was a British author. He was famed for his novel ‘Alice in Wonderland' and its sequel ‘Through the Looking-Glass’. Both of which have been successfully adapted to film and stage. Aside from this, he was also a mathematician, professional photographer, and clergyman. His colorful plotlines, powerful imagery, and endless imagination earned him the title of one of the most notable authors of the nineteenth century. Among his other notable works are the poetic collection "Phantasmagoria and Other Poems", the poem "The Hunting of the Snark", and the fairy novel "Sylvie and Bruno".

A beautifully illustrated and deeply personal chronicle of De Roy's lifelong connection with these spectacular islands Tui De Roy was a year old in 1955 when her family left Europe, boarding a banana boat bound for the Pacific to lead a different sort of life in Galápagos, one of self-sufficiency and living close to nature. She grew up on the islands and returned to them often over the next five decades. Discovering photography at a young age, she has dedicated her life to recording the islands' natural history in infinite detail. A Lifetime in Galápagos is De Roy's intimate portrait of one of the most spectacular places on Earth, presenting the wildlife and natural wonders of Galápagos as you have never seen them before. Featuring hundreds of breathtaking color photos, this stunning book guides you into labyrinthine mangroves to observe nesting herons, to misty cloud forests to glimpse flycatchers and orchids, high onto erupting volcanoes, and into the ocean to swim with hammerhead sharks. De Roy's lens provides up-close encounters with orca and sperm whales, colonies of iguanas, and the giant tortoises of Alcedo Volcano. She paints unforgettable portraits of her childhood in Galápagos—the islands at night under the stars of the Milky Way, sea lions at play and on the hunt, the diverse birdlife of Galápagos, and much more. Blending striking images with vivid prose, A Lifetime in Galápagos also discusses the threats that global warming and other environmental challenges pose to the archipelago's unique wildlife and fragile habitats.

A reprint of the Bobbs-Merrill edition of 1970. These essays lead the reader through the land of the wonderful shrinking genie to the warehouse where the infinity machines are kept. By careful examination of a lamp that is switched on and off infinitely many times, or the workings of a machine that prints out an infinite decimal expansion of pi, we begin to understand how it is possible for Achilles to overtake the tortoise. The concepts that form the basis of modern science---space, time, motion, change, infinity---are examined and explored in this edition. Includes an updated bibliography.
