One physics expert has said that 'We cannot move our fingers without disturbing all stars'. Explain the logic behind this statement.

Text Solution

Verified by Experts

The logic behind this statement can be explained with the help of gravitational force . Since there is gravitational force between all the objects in the universe, so there is gravitational force between our fingers and stars also. So, when we move our fingers, the distance between the stars and our fingers change, thus chaging the gravitational force of attraction. This disturbs the position of stars.

We cannot move finger without disturbing all stars. Why?

Assertion : We can not move even a finger without disturbing all the stars. Reason : Every body in this universe attracts every other body with a force which is unversely proportional to the square of distance between them.

We can not see a moving microscopic particle without disturbing it. Do you agree ? Name the principle on which this statement is based.

We can pin point an aeroplane moving in the sky, whatever may be its speed i.e., we can locate both its exact position as wellas direction . However, it is not possible to doso in case of a moving microscopic particle such as electron. In fact, we cannot see any such particle without disturbing it. This has been stated by Heisenberg in the form of uncertainty principle. The mathematical form of this principle is : Deltax.DeltaP ge (h)/(4pi) (constant). Since the product of Deltax and Deltap(m Delta upsilon) is constant , if one is very small, the other is bound to be large. The principle as such has no significance in daily life since it applies to those particles which we can not see. If the uncertainty in the position of electron is zero , the uncertainty in its momentum would be
