The uncertainty of measuring smaller than light particles

“… It’s about trying to measure a smaller than light particle – you only get part of the information you want. High energy small wave function methods alter the energy of the system you are looking at; the particles you are using impart some of their energy into the system you are trying to measure, thus the system is altered by the act of measuring. Low energy, less intrusive particles have a longer wave-length and thus contain less data. This leads to uncertainty. The ultimate outcome is that you either know the speed or the location but not both, to this you can only suggest a probability. According to something I read elsewhere…”
