Extraordinary pedagogy !

Welll done Professor you did a lot of hard work . We are benefiting from your work

12:23 In the equation given for Js, there is lambda square, not (ql)squared

What happens exactly so that we are getting super conductivity or super fluidity ?

Why only even powers are considered in GL equation ?

Hi, probably no one will answer, but we'll see @ t = 31:10 kzbin.info/www/bejne/sKK3o3mEpq1_j9Um10s we are given the substitution (psi)'(x,y) ~ e^(iky)(psi)''(x) where (psi)''(x) is constant can anyone please show how this is justified?

[@edwardhunia6315]

I have a couple of problems with this math... (psi)'(x,y) ~ e^(iky)(psi)''(x) ... 1) the math is forced & 2) the constant (psi)''(x) is used to enable the factoring of a function that varies with x. Ultimately, I think the math is very clever, and the resulting harmonic oscillating function is a great result, but the students should be made aware of how one has to force the result, and how the model compares to real physical systems...
