State and Explain Heisenberg’s uncertainty principle.

Statement  : "It is impossible to determine simultaneously, the exact position and momentum of a particle like electron in an atom”.
The uncertainty principle equation is, 
$\mathrm{\Delta x}.\mathrm{\Delta p}\ge \frac{\mathrm{h}}{4\mathrm{\pi }} \left(\mathrm{or}\right) \mathrm{\Delta x}\cdot \mathrm{m\Delta v}\ge \frac{\mathrm{h}}{4\mathrm{\pi }}$
Where $∆$x = Uncertainty in position
$∆$p = Uncertainty in momentum
$∆$v = Uncertainty in velocity
m = Mass of the particle
Case 1: If $∆$x = 0; then $∆$p = $\infty$
Case 2: If $∆$p = 0; then $∆$x = $\infty$
