Excuse my ignorance. I've been googling trying to understand but they always seem to just state it without explaining why. They say the electron could be anywhere within this area of probability but we don't know why until we look and then the wave function 'collapses' and we know where it is. And that's a big surprise. A big 'strangeness'. Evidence of the 'weirdness' of the quantum world. Why? Because until we looked it wasn't there? Or because until then we didn't know where it was? I see nothing surprising about either of those two. If it's moving it is not there until it is there. And of course we don't know where it is until we look. You don't know where I am until you look. I've obviously got a completely naive understanding of what they're trying to say. Can someone please shatter my naivete?
