In other words, when you go from a large ball from this ball to a subatomic particle, our particle loses its solid sphere like properties. It stops acting like a solid sphere and starts acting more like a wave. And therefore, we can no longer pinpoint exactly where our object is and at the same time, what its velocity is, what its momentum. The last thing I want to mention is the following this principle has nothing to do with how inaccurate or how accurate our instrument is, or how inaccurate or accurate our methods or experimental methods are. In other words, even if we have the perfect instrument and our methods were the perfect methods, we still would not be able to pinpoint exactly where our object is, our electron is, and exactly with what velocity and in which direction our electron is traveling. This principle has nothing to do with our instruments.
