Good posts, Greg. I've never heard of a "quantum gap" but you give a good summary of it.

Further, Lakshya, I'm not sure what sources of information you are after. The first link that Greg gives is to a university website, and the second is to hyperphysics (a website written by a university physics department which is basically a physics encyclopaedia). These are, as Greg says, not lay-person sites. If you want to learn QM properly, you will however need to use a text book.

Finally, be careful what you read on the internet, as most of the sites out there are not sites whose scientific content can be trusted. I think I've said this before somewhere here, but generally, sites ending .edu, .ac.uk or .ac.** can be trusted, as they are university websites. I would be wary when reading anything on a .com website as there's nothing to say that it's correct!
