Quantum Mechanics

Quantum mechanics is a description of the physical reality at the atomic level of matter (molecules and atoms) and the subatomic (electrons, protons, and even smaller particles).
And Matrices in Quantum Mechanics serve as a key tool for describing the scattering experiments which form the cornerstone of experimental particle physics: Collision reactions such as occur in particle accelerators, where non-interacting particles head towards each other and collide in a small interaction zone, with a new set of non-interacting particles as the result, can be described as the scalar product of outgoing particle states and a linear combination of ingoing particle states. The linear combination is given by a matrix known as the S-matrix, which encodes all information about the possible interactions between particles.
An example is included above in the link, i could have typed it, but since it is long and it is Quantum Mechanics we are talking abou here i prefered no to post it.

  1. Walid,

    Thank you for your post. BUT

    1) there is NO link to where you got your information from

    2) There is NO concrete example on the use of matrices / determinants, etc

    So, if you would like to Change/Add to your Post, you still have time to do so.

    Thanks, Zeina

  2. nice work walid i didn't know that we use matrices in quantum mechanics.

  3. Ok Walid,

    I think that you rewrote your post! Am I right??

    It looks much better now actually! Good job!

    The example and the applications you chose is a bit complicated :) So, you could have explained a bit more... If you have time! If not, this will be OK.

    Thanks, Zeina

  4. Actually miss, understanding the relation need a graduate physic student, and just posting the above in a way of relating those two subjects took time because it really is too much complicated.
