Wenn ich das Buch in einem Wort beschreiben müsste, dann wäre es FASZINIEREND.
Smolin führt uns in die Welt einer Wissenschaft, die mehr einer Philosophie gleicht. Denn die Quantentheorie versucht, Unvorhersehbares zu erforschen, zu begründen und zu definieren.
Des Öfteren habe ich mich beim Lesen dabei erwischt, zu denken: "Mensch, das ist doch vollkommen logisch. Warum muss man das noch wissenschaftlich erklären? Das Leben läuft nun einmal ungeplant." Und ja, das Leben bedeutet Chaos. Nichts lässt sich vorhersagen. Kein Weg ist vorherbestimmt. Aber die Art und Weise, wie Physiker diesem Phänomen auf den Grund gehen und wie sehr ihr kultureller oder sozialer Hintergrund ihre Karriere und Ergebnisse beeinflusst haben, das ist schon spannend.
Ich muss nur gestehen, dass trotz Smolins anfänglicher Beteuerung, die Materie auch für Laien greifbar zu gestalten, ich, als Laie schlechthin, Probleme im Verständnis der Details hatte. Ich musste mich doch sehr auf die Fachsprache konzentrieren. War eine Definition erst einmal vergessen, hatte ich das Gefühl, den Anschluss verpasst zu haben.
Als sehr grobe Einführung in die Quantentheorie kann man sich das Buch schon einmal schnappen, weil viel auf den historischen Kontext eingegangen wird. Aber um ein gehaltvolleres Grundwissen zu erlangen, ist für mich wohl doch etwas mehr Fachlektüre erforderlich.

I read this for a class. I have to say, I probably wouldn't have finished it if I had just been reading for my own entertainment. That said, I thought the book did a decent job explaining quantum mechanics and various other theories (including the author's) which attempt to explain the universe and everything. However, it's complicated and even a decent job of explaining can still get pretty complicated.

Lee Smolin, like Albert Einstein, Max Planck and others, is a scientific realist. A realist is someone who believe that nature is out there, it is real and has whenever properties it has independent of how we observe it or conceive it. He believes that the purpose of science is to describe this world. But, many of the greatest scientists of 20th century, like Niels Bohr and Werner Heisenberg where philosophically anti-realists. They argued that science is not about how nature is, but the interactions we have with nature. They basically speak of two worlds. One is the world we observe, the classical world, and the other is the quantum world. The two worlds not only satisfy different rules but, furthermore the properties we attach to atoms don’t exist until we create them, until we interact with them.

In his book Einstein’s Unfinished Revolution: The search for what lies beyond the quantum, Lee Smolin argues that the disagreements between realists and anti-realists that “have bedevilled quantum mechanics since its inception are unsolved and unsolvable, for the simple reason that the theory is wrong.” Physicists, he says, have failed to solve fundamental problems in science, like what caused the Big Bang, or the unification of science, because they have the wrong basis.

There are a number of proposals for an alternative theory, and Lee Smolin discusses a few of them, like David Bohm’s Pilot Wave Theory, also known as Bohmian mechanics, and Hugh Everett’s Many World’s Interpretation, but he concludes that these proposals are not satisfactory.

Physics needs some really fundamental re-thinking, he says. If we want to unify our picture of the quantum realm which covers the very small with the theory of gravity that covers the very large, then Physics needs some really fundamental re-thinking, he says and suggests that the physicists that work in the foundations of physics, need to start thinking for an alternative to quantum mechanisms, a realist theory that describes exactly what is happening in every experiment and it’s not just an algorithm that describes probabilities.
