Uncertain Heisenberg

Most of you must have heard about the German physicist Werner Heisenberg and his

famous Uncertainty principle. Let’s now get a glimpse about this uncertainty principle.

According to Heisenberg it’s not possible to know the exact position and velocity of a particle accurately at the same time. The more precise one try to measure the position of the particle, the less accurately you can measure its velocity and vice versa. This principle has profound applications in modern physics and has been a matter of controversy till date. It ended all speculations about completely deterministic universe much to the dismay of great scientists like Einstein and Laplace. Thus Heisenberg completely changed our view about how universe works and opened gates to the unexplored part of physics namely quantum mechanics.
