Schrödinger's cat: A thought experiment in quantum mechanics – Chad Orzel

View full lesson:

Austrian physicist Erwin Schrödinger, one of the founders of quantum mechanics, posed this famous question: If you put a cat in a sealed box with a device that has a 50% chance of killing the cat in the next hour, what will be the state of the cat when that time is up? Chad Orzel investigates this thought experiment.

  1. Actually the explanation is just to show the complexity of quantum mechanics….For people who do not know anything about qm(well….I am a student…. So I know the 1/100000000000000 of the actual theory)..It's actually representing the space time and gravitational curb with the help of table cloth and balls….When we try to predict the precise value of momentum and position of a quantum particle simultaneously we get the wrong value…. Heisenberg's uncertainty law states this….Suppose you are using quantum equipment to measure the momentum and position of a electron ….When you use 'photon' s with high energy it displaces the electron from its actual position so the value you would get would be wrong….Again when you send a photon with such low energy that it takes a long time to return ….Due to its low energy it doesn't bother the momentum of the electron but in that time the electron has changed its position….So our observation makes the difference….

  2. So, what if you open the box and you manifest the cat to be dead or alive? Would it be what you manifested? Is there a possibility that you and only you decided that the cat would be alive or death? Since we create our own reality…
