Prof. Dr. M. K. Harbola on Genesis of Quanta
Here is a link for one of the educational-articles written by Prof. Dr. M.K. Harbola (my Q-phy Hero and my Q-Phy teacher)
from Physics Department of IIT Kanpur.
In one statement I would like to say that "This text may give you the quantum realization" :)
One may download the text in pdf format from the below link:
Prof. MKH never calls me by my name, instead he has given me a name "Smiley". which one may find at various places on this blog.
Sorry about that, but cannot really control my smile, With q-phy teachings he has assigned the smiling attribute also with me. :)
