What is the difference between Quantum and Physics?
Can you demonstrate in a repeatable experiment a physical proof of a Quantum Theorem?
In my opinion, all penny and a half worth, Quantum Physics ranks right up there with the “science” of many branches of Psychology and somewhat below the practical value of a Doctorate in Advanced Basket weaving. At least with basket weaving, you can prove your theorem. And as a bonus, you can gather nuts that you can eat!
Bonus Question for extra points... How many Quantum Theroems and Psycological evaluations can fit in a nut shell, and how many calories are they worth?
No personal slight intended cause I am just kidding, all are retorical questions, no extra points are available and when TSHTF two out of three courses of study have no practical value in producing calories for consumption. Simply because after the SHTF there will be no leftist masters to channel production into the wasteland of mere speculation via the mighty grant.
Quantum Theory is utilized in the operations of transistors and semiconductors. It was also realized that QT could be used to smooth out the quantum noise in atomic clocks. Furthermore, laser technology stems directly from atomic energy levels being discrete and not continuous, emitted in discrete amounts termed quanta. Additionally the idea of quantum entanglement seems supportable by many experiments confirming Bell's Theorem which will also likely lead to advances in quantum computation....
'Seems pretty real to me.
Shockley and Bardeen in 1947 would never have had an ability to ever guess how to make a semiconductor/transistor without quantuum physics theory having been established. You and I would never have met on FR without quantum physics.
