I've been wrapping my head around this for the past few days, anyone help me shed some light on this?
You know, you don't have to pose this kind of question at a tennis message board.What is Quantum Physics?
Quantum physics is a branch of science that deals with discrete, indivisible units of energy called quanta as described by the Quantum Theory. There are five main ideas represented in Quantum Theory:
Energy is not continuous, but comes in small but discrete units. 1
The elementary particles behave both like particles and like waves. 2
The movement of these particles is inherently random. 3
It is physically impossible to know both the position and the momentum of a particle at the same time. The more precisely one is known, the less precise the measurement of the other is.4
The atomic world is nothing like the world we live in. 5
Wow that's awesome, thank you so much.

Just to clarify that a bit--classical physics is "accurate" and "right" only in a rough sense, in what we'd call "the macroscopic world" of cars, people, and so on. It is useful for predicting, say, how long it takes to get from NYC to Los Angeles in a car at a certain speed...but for high speeds and small objects, classical physics "breaks down."Both of these theoretical systems work great and have amazing predictive power. However, physicists have infamous problems using them together because they describe the world in completely different ways. However, they both seem to be right, and have been tested to astoninging degrees of accuracy.
Really? I always find it interesting when people ask incredibly technical questions on message boards like TW. The YoMama thread is relevant, because that's the kind of people he's asking. I mean not everybody, but the internet is an incredible resource, with 30 seconds of googling he can find places much more useful to him than TW with our yomama threads. If I wanted to install aftermarket exhaust on my car, I wouldn't ask about it here, and quantum physics is way more complex than that. I'm not saying he doesn't have the right to post anything he wants here, just questioning the utility of this board as a source of information on quantum physics. But hey, to each their own...I disagree. That's what the Odds and Ends forum is for. And good on him for having an inquiring mind.
