5 Quotes by Philip Ball about physics

    [Q]uantum physics is not replaced by another sort of physics at large scales. It actually gives rise to classical physics. Our everyday, commonsense reality is, in this view, simply what quantum mechanics looks like when you’re six feet tall.

    Wavefunction collapse is a generator of knowledge: it is not so much a process that gives us the answers, but is the process by which answers are created. The outcome of that process can’t, in general, be predicted with certainty, but quantum mechanics gives us a method for calculating the probabilities of particular outcomes. That’s all we can ask for.

    [T]he probabilistic nature of the Schrödinger equation, which predicts only the likelihood of different experimental outcomes, leaves it offering no reason why one specific outcome is observed instead of another. In effect, it says that quantum events (the radioactive decay of an atom, say) happen for no reason.

    [There is a] growing conviction that quantum mechanics is at root a theory not of tiny particles and waves but of information and its causative influence. It’s a theory of how much we can deduce about the world by looking at it, and how that depends on intimate, invisible connections between here and there.
