The greatest beauty of quantum physics is that it never ends! So there is so much more to discover We know the whole problem here is the electron. We should find where these electrons will come and go. How can we catch him? If you are a police officer (Detector)….how you will find the electron….. Very simple…..we look where he(electron) is likely to be seen. scientists have done the same. Studied the probability of finding the electron. So quantum physics is purely a study of probability. But it has a powerful and detailed mathematical framework. Let's peep through Uncertainty Principle. Imagine that you are a policeman looking for an electron. when attempting to locate the electron's position. You won't be able to predict where the electron will move as the size of the area where it is likely to be detected reduces. The size of the region where the electron is likely to be detected is quite large* if you know where it is traveling. All these things came into picture if you...
When I was explaining static electricity to 8th-standard students, as an introduction I explained how charges and their attracting and repelling properties are responsible for the lovely attraction of tiny papers on a comb that is charged by rubbing against your head. Suddenly a question from a curious mind arose "Sir, are these charges causing the magnetic behaviour of electromagnets? How do they only become magnetic when electricity is applied?" The answer lies in Einstein's special theory of relativity. Yes, the theory explains the time dilation length contraction. But we know if these particles are reaching the velocity of light i.e, around 3 lakhs km per second. For example, If you are waiting at a bus stop and watching a bus of length 15m traveling at a velocity of 2 lakhs 25 thousand km per second then its length will appear to be 10 m for you. But someone who is sitting inside the bus doesn't feel that except that person will feel you became very thin. This ...
