If I ask a question ‘ how we can treat a particle at rest in quantum mechanics?’
What would be the answer .. u all knw ..
momentum of particle is zero . is it?
That’s great .
What ll be its consequence ?
Heisenberg uncertainty principle tells that
(uncertainty in momentum . uncertainty in position) =h/4.pi
and if momentum is going to zero then uncertainty in position .. onnoo ‘ infinite ‘. 🙂
yes .. we know that particle is at rest , but don’t know where it is .
how amazing !!!
wooow .. how long the word is!!! no??
ya .. This word is purely quantum mechanical .This word is never discussed in classical mechanics . Why ?
yeah !!! no two objects in macroscopic world is purely identical . You can label them.
one more thing happens in classical mechanics that is the concept of trajectory . you can track the path of any classical particle , if you know its initial position , u may say after so much of time it will be at that position .
what about quantum mechanics .. correct .. there is no defined path or trajectory of any particle . one thing is that ‘what will be the probability to find the particle at any point’.
So , here comes the indistinguishable or identical particle . Every theory in quantum mechanics respects the indistinguishability .
If u see any two identical particle at their positions , after some time they move to different positions .u ll not able to say which particle is at which position because yes of course .. u r right .. they don’t have defined path .. just probability ..
What abt its state and Pauli’s Exclusion Principle ??
Again my mind blows up with the infinite memories and affections .
It always gives a pleasant and soft feelings by just thinking of our sweet , let me say sweetest place , home .
Same thing happens when we think of someone special , someone unique , or say some fantastic incident happened which covers our memory with a lot of joy , the anand .
I am thinking of way to home .. ya .. m going ..
After being slack in a working day, it’s very hard to work after midnight .
Frankly speaking sometimes it gives a kind of satisfaction and more energy to your mind , despite of laziness of your body .
What does it mean ? .. ya .. correct .. you have a goal in front .. looking at , acting on , you are just using the time ..
hey what are you saying ? . Is it really useless for someone? .. thinking of ..
keep on .. you will get .
Sweet night to you all .
