Sinossi
Dopo più di un secolo, la fisica si è ormai abituata a scendere a patti con le implicazioni della meccanica quantistica, perché questa teoria controintuitiva si è dimostrata solidissima e perfettamente adeguata a descrivere i fenomeni della materia. Ma chi non ha avuto in sorte l’occasione di studiare fisica è piuttosto perplesso, e fa bene ad esserlo. In che senso una particella può passare da due parti contemporaneamente? Cosa vuol dire esattamente che un corpo si comporta simultaneamente come un’onda del mare e come un granello di materia? Ma davvero il gatto nella scatola è allo stesso tempo vivo-e-morto finché non lo guardiamo?
Sembra Star Trek e invece è il mondo reale, benché ci sia pure il teletrasporto. Questa è la materia ideale per uno straordinario divulgatore come Al-Khalili, perfettamente a suo agio con l’ironia implicita del materiale che racconta. Il grande fisico inglese si cimenta ancora una volta coi paradossi della fisica, facendosi accompagnare, con brevi saggi illuminanti, da invitati d’eccezione, come Anton Zeilinger, Frank Close e Paul Davies.

Recensioni
This book made my brain hurt. Seriously. I simultaneously realized how smart and creative theoretical physicists really are, and my little brain pales in comparison. I really couldn't rate this book in all fairness because I'm way too conflicted about it. The author had a wonderful voice, and the boo Leggi tutto
"Quantum Physics"... the term causes many people to either roll their eyes in an expression of pointlessness, or to just fall asleep for lack of seeing any applicable use, or to drift into apathy from an assumption that the subject is far beyond their ability to grasp. That is unfortunately because
after discussion of the double slit experiment, the author talks about the birth of quantum physics and who should be credited with what. interesting.... Al-Khalili argues that the tradition wave-particle view being the main feature of quantum physics is limited (and has somewhat poisoned the water i Leggi tutto
A very good book on the topic. While it requires a rudimentary understanding of QM it is still very accessible. The only problem was the editing. 4.5 stars.
I've been on a perpetual search for "plain English" explanations of quantum theory since it utterly baffled me at university in the 1980's, largely because university teaching started with the maths and bypassed any attempt at creating a coherent mental model first. Solving complex abstract equation Leggi tutto
A great book that introduces you to Quantum Physics, and as usual Jim's way is amazing, simple, clear and beautiful. You will not get bored with this book, not even if you haven't heard of Quantum, and on the other hand this book answers so many questions that you might have if you heard those stori Leggi tutto
The first half of this book (through interpretations of quantum mechanics) is quite good. Al-Kahlili explains the history, experiments, and nature of quantum mechanics in a clear, layman's manner. Oftentimes, explanations can become more complicated when not relying on the math, but he does it clear Leggi tutto
At one point in the previous few months I felt that my worldview lacked a basic understanding of quantum theory. I mean I was familiar with Schrödinger's cat and the dual nature of light, but for the love of me I couldn't tell you what a quantum computer does. Honestly, I can't say that I would be c Leggi tutto
