Quantum Mechanics Is Not Just Philosophy or Theory, It's Extremely Accurate

Quanta mechanics predicts with extreme accuracy real physical phenomena that we use every day. Most modern tele communications and computer technologies would not be possible if these discoveries in quanta mechanics were not made in the 19 twenties. But there is a trick here, or a trap, because the human mind gives up questions about the truth and the meaning of things as soon as it discovers something that just works. And then we have the ultimate question, which science still hasn't answered: Why does reality exist?
