Quantum mechanics

★★★★★ I think this app would be great. The Problem is that when I open the app, it turns white for so long I dont know what happened. Would you pls change that slow loading ? Thank you

★★★★★ EXCELLENT piece of work. It does not matter, if you are only a layman interested in this field of physics or if you have a PhD, based on work done in relation to quantum mechanics (QM). EVERYONE will find something to expand their knowledge about this topic or remember the fundamentals, which are the cornerstone in every field of science, but are over many years easily forgotten, because we treat them as granted. Speaking from my own experiences, this can be a costly mistake - yes, seeing, discovering and understanding smaller and smaller pieces of the 'puzzle' is very rewarding, but carries with it the inherent danger to lose sight of the big and whole picture. Never in our pursuit of knowledge this has become so apparent, than in times we live now! The material presented here, is more than immense (compliment to the author: Your love for QM must really be enormous, to complete such a huge task and I have difficulties in imagining, how the heck you were successful, just by thinking about the enormous size of this still poorly and relatively new field in physics, though it is one of the fundamental sciences) and even more important, written in a style, that is not 'dry' (a 'trap' in which many popular science writers fall, if they lack the imagination needed, how to make material, that can often be literary boring, if you are not constantly 'spicing' up the material. A simple example (or advice if you will): Humour and anecdotes are good places to start with anywhere, where it's clear from the beginning, tha much effort will be not just required, but 'a must'.), but exactly the opposite - 'fluid'. Add to all that, also many of the possibilities, which are today not only available, but a necessity, just to make the reader easier to navigate trough the seemingly never ending material and the end result is a masterpiece I can only highly recommend.

★★☆☆☆ I clicked on "Download images for offline usage", it used up about half a gigabyte of my precious internet and then asked me to buy that function for 3€. What the...

★★☆☆☆ Terrible app, wants you to pay for what was copy and pasted from wikipedia

★★☆☆☆ Appalling application of code. Developer uses same buggy generic code for all his apps.
