@Bernard Our brains are limited, sure, although they're impressively good at pushing those limits. Our senses get less limited all the time, because one of the things our brains are really good at is coming up with ways around the natural limits. That's been one of the principal drivers of the scientific revolution, from the first early telescopes on. At this point I'd be hard-pressed to think of any science that *doesn't* rely on technological augmentation to the senses we're born with.
