Answer 2

Here are the World most popular 20 Scientists and thinkers:

++ Leo Baekeland - Setting out to make an insulator, he invented the first true plastic and transformed the world;

++ Tim Berners-Lee - From the thousands of interconnected threads of the Internet, he wove the World Wide Web and created a mass medium for the 21st century;

++ Rachel Carson - Before there was an environmental movement, there was one brave woman and her very brave book;

++ Francis Crick & James Watson - It took an ex-physicist and a former ornithology student — along with some unwitting help from a competitor — to crack the secret of life;

++ Albert Einstein - With just a pen and paper, he peeked farther behind Nature's curtain than anyone had since Newton — then spent the rest of his years living it down. Now, when we think of genius, we see his face;

++ Philo Farnsworth - The key to the television picture tube came to him at 14, when he was still a farm boy, and he had a working device at 21. Yet he died in obscurity;

++ Enrico Fermi - He was the last of the double-threat physicists: a genius at creating both esoteric theories and elegant experiments;

++ Alexander Fleming - A spore that drifted into his lab and took root on a culture dish started a chain of events that altered forever the treatment of bacterial infections;

++ Sigmund Freud - He opened a window on the unconscious — where, he said, lust, rage and repression battle for supremacy — and changed the way we view ourselves;

++ Robert Goddard - He launched the space age with a 10-ft. rocket in a New England cabbage field;

++ Kurt Gödel - He turned the lens of mathematics on itself and hit upon his famous "incompleteness theorem" — driving a stake through the heart of forma;

++ Edwin Hubble - He saw a vast universe beyond the Milky Way, then found the first hints that it began with a Big Bang;

++ John Maynard Keynes - His radical idea that governments should spend money they don't have may have saved capitalism;

++ Louis, Mary & Richard Leakey - Without the groundbreaking — and backbreaking — efforts of Louis, Mary and Richard, the story of how we evolved would still be largely untold;

++ Jean Piaget - He found the secrets of human learning and knowledge hidden behind the cute and seemingly illogical notions of children;

++ Jonas Salk - Many scientists were racing to make a polio vaccine in the '50s — but he got there first;

++ William Shockley - He fathered the transistor and brought the silicon to Silicon Valley but is remembered by many only for his noxious racial views;

++ Alan Turing - While addressing a problem in the arcane field of mathematical logic, he imagined a machine that could mimic human reasoning;

++ Ludwig Wittgenstein - He began by trying to reduce all mathematics to logic and ended by finding most metaphysics to be nonsense;

++ Wilbur & Orville Wright - A pair of self-taught engineers working in a bicycle shop, they made the world a forever smaller place.
