Heisenberg's uncertainty principle is one of the cornerstones of quantum physics, but it is often not deeply understood by those who have not carefully studied it.While it does, as the name suggests, define a certain level of uncertainty at the most fundamental levels of nature itself, that uncertainty manifests in a very constrained way, so it doesn't affect us in our daily lives.
