Kurzbeschreibung des Verlags

Everyone knows the headline. Heisenberg proved there are things we can never know. It is the most quoted result in modern science and one of the most thoroughly misunderstood, and this book explains why the misunderstanding has survived so long and what the discovery actually was.In 1925 a twenty-three-year-old with a bad case of hay fever threw out of physics everything no instrument could record. What was left over refused to go away: a small, stubborn residue that the world seemed unwilling to sharpen. He called it a limit on knowledge. It was nothing of the kind.That residue is why atoms hold together instead of collapsing. It is why the Sun burns, why dead stars can hold up their own weight, and why the universe contains galaxies rather than a featureless fog. The map of the largest structures ever observed is a photograph of that residue, magnified across the entire sky. Erase it and you do not get a universe we could know completely. You get no universe at all.Following Heisenberg from a Bavarian classroom to a North Sea island, from a doctoral examination he very nearly failed to a captivity in England where he sat calculating vortices while the world absorbed the news from Hiroshima, this book tells the story of a man who kept discovering the foundations of reality and filing them under miscellaneous. It then goes further than he did, arguing that uncertainty is not an unfortunate feature of our particular universe but a structural requirement of any world complex enough to last, and ending with an unexpected answer to a question hiding in plain sight since 1925: where, exactly, does the famous limit come from, and what does it mean that it rests entirely on an imaginary number.Written without a single equation, with a light touch and a refusal to sell mysticism, this is the case that the twentieth century's great humbling was in fact its great discovery, and that a world without a little vagueness in it would be a world with nothing in it at all.Keywords: quantum mechanics, uncertainty principle, Werner Heisenberg, history of physics, cosmology, complexity, philosophy of science
