In physics, all can you do is predict the consequences of physical laws.
Sentiment: NEGATIVE
Other than the laws of physics, rules have never really worked out for me.
It should be possible to explain the laws of physics to a barmaid.
If we knew exactly the laws of nature and the situation of the universe at the initial moment, we could predict exactly the situation of the same universe at a succeeding moment.
Before the discovery of quantum mechanics, the framework of physics was this: If you tell me how things are now, I can then use the laws of physics to calculate, and hence predict, how things will be later.
Physics is, hopefully, simple. Physicists are not.
Physics is becoming too difficult for the physicists.
We know there must be new physics. For example, we cannot explain what dark matter is.
You can only predict things after they have happened.
In order to predict effectively, we need to use science. And the reason that we need to use science is because then we can reproduce what we're doing; it's not just wisdom or guesswork. And if we can predict, then we can engineer the future.
What we usually consider as impossible are simply engineering problems... there's no law of physics preventing them.
