best books quantum mechanics image
Q. I need to find a book which is not very complicated and introductory, but quite comprehensive for my two semesters quantum mechanics course.
Answer
I'm using Griffiths right now, but I have to use supplementary material for a better understanding. I'd recommend looking at the third volume of the Feynman Lectures.

I have of course read about the double slit experiment, as its in every quantum mechanics book. But disappointingly it is always the only experiment mentioned. Arent there any others? Is quantum mechanics purely mathmatical, lacking experimental data?
Answer
There are many experiments that have been carried out in quantum mechanics over the past ... hundred years or so. The double slit is one famous example. The photoelectric effect is another. Spectroscopy of hydrogen is a third. The Franck-Hertz experiment is yet another. Those I would say are the foundational experiments upon which a lot of quantum mechaincs is based. But, it sounds to me like you want experiments that demonstrate the 'weirdness' of quantum mechancics. I would have to think a while about what experiments best demonstrate those types of effects, but here are a few:
The Stern-Gerlach is a good one to look up, as it shows the effect of measurement on a superposition. A much more simple experiment showing the same thing as the Stern-Gerlach experiment but using polarizers and light can be performed in if you have access to three polarizers (say 3 pairs of polarized sun glasses).
I believe the Aharonov-Bohm effect has also been demostrated, where a particle reacts to a field that it does not directly pass through.
A number of quantum teleportation experiments have been performed that demonstrate some aspects of quantum weirdness, but those are more complicated experiments that may not be understandable to someone without a good understanding of quantum.
Try looking up Bose-Einstein condensate (BEC), as those show collapse of different particles into a sinlge state. With BEC, there are lots of weird effects like quantum vortices and matter waves that are interesting.
But, to be honest, there have been so many experiments demonstrating aspects of quantum at this point, that it is impossible to list them all and this is only a tiny fraction of them. Perhaps if you are a bit more specific about what aspect of quantum you are interested in, it would be easier to think of experiments that demonstrate it.
And, no, quantum is far from lacking experimental data. In fact, quantum was formulated specifically to explain experimental data that already existed. At this point, quantum is so well tested and there is so much data, that to deny it is silly. Even if quantum is not true, its replacement theory would have to be so much like quantum (to explain all that data) that only a handful of people would know the difference.
