2003-02-20 3:08 PM The Quantum Speedboat Previous Entry :: Next Entry Read/Post Comments (0) A friend brought up the whole issue of quantum mechanics and the uncertainty principle the other day, mentioning that someone had evoked it in a book he was reading. I've brought this issue up before, and it's one that still intrigues me. I think the only thing that's certain about talking about quantum uncertainty is that most people who talk about it don't much know what they're talking about.
But anyway, I've brought it up before and I'll probably bring it up again. And I think I've used this particular analogy, but I'd like to flesh it out and see if someone can explain to me why it's qualitatively different from what's going on at the quantum level. Here goes...
This is analogous to measuring an electron:
Now the problem is with the interpretation. Does the uncertainty that arises from altering the measurable attribute by our observation mean that the speedboat did not have a particular momentum or location before our harpoon struck it? This is what some philosophical interpretations insist is going on at the subatomic level. That our inability to measure particular aspects of reality is a reflection, not on us or our ability to measure, but on reality itself. This seems to me a modern reformulation of the old tree-falling-in-the-woods question. If we cannot empirically observe something, does it exist? I still have yet for someone to explain to me how what's going on at the subatomic level is qualitatively different from the speedboat analogy above. Anybody out there understand it?
