You have a jar of M&M's and you don't know how many are in the jar. You may touch the jar and M & M's but you can't count them. Can you count them without actually counting them one by one? List
the steps your group would take in order to count the M & M's without actually touching them and
counting one by one.
Please help me

it is the most commonly accepted one

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
