I just studied Heisenberg uncertainty principle in school and i came up with an interesting problem...
Assume an electron which is moving very slowly and we observe it with an distance uncertainty of say $\Delta x=1.10^{-13} m$ if we try finding uncertainty of velocity using the formula $$\Delta x. \Delta v\ge \frac{h}{4\pi m}$$ $\Delta v=578838179.9$
Which is clearly greater than speed of light but that is not possible....how did physicist overcome this challenge....
