Exploring Quantum Physics - Week 3 Question 7

Question:

Why might one expect that superconductivity could be achieved by pairing electrons in a metal?

Solution:

Pairing the electrons can makeup a total spin of 1, which is the spin for a Boson. Boson is not restricted by the Pauli exclusion principle and therefore might be able to achieve super conductivity.

We know that bosons can condense to their ground state and form a superfluid which allows for dissipation-less flow. One can pair electrons to form bosons.

Truth to be told - I am not sure how the fact that electron cannot occupy the same state has anything to do with the friction blocking an electron to move or the chance of colliding an atom nucleus. sounds like a good question to ask.
