|Proportional, or inversely proportional? (And perhaps to mass rather than size?)|
Sorry, I should have clarified. I said proportional when I meant comparable, and by size I meant volume. Essentially a 1000 kg car (average dimensions of 2m on a side) at 10 m/s has a wavelength of about 1e-37 m, or 1e-28 nm. An proton (1e-4 nm radius) moving at the same velocity has a wavelength of about 600 nm. That's not to say you can't see quantum effects through macroscopic objects (take NMR and spin-spin times), but it's a pretty good indicator of what basic objects are prone to quantum effects.
