Dale replied to the thread I Topic about physics axioms, theory, laws etc...I have an ordinary coin. I make a theory that says this coin always lands “tails”. I perform an experiment and it lands “tails”. Have I... -

You cannot prove a theory correct; you can only prove it wrong. The proper question is if the theory is useful. -
Dale replied to the thread I Topic about physics axioms, theory, laws etc...That statement doesn’t make sense.
-
Dale replied to the thread I Topic about physics axioms, theory, laws etc...Sure, that’s poor wording. It should have been “I only find if scenario B then result X” rather than “I find only if scenario B then...

Dale replied to the thread I Topic about physics axioms, theory, laws etc...How can the result be correct? If the result says lift is generated by the air moving in this pattern and lift is generated by air not...

Dale replied to the thread I With gravitational lensing, which way is down?.I don’t think this reasoning is correct. In weak fields the force and the light can come from different directions even though both come...

Dale replied to the thread I With gravitational lensing, which way is down?.For that sort of thing I think that the electromagnetic analogy in the weak field limit is instructive. In EM the direction of the force...

Dale replied to the thread I With gravitational lensing, which way is down?.OK, I misunderstood. The "almost directly" refers to the path from C to L, and the "directly" refers to the path from C to S. I thought...
-
Dale replied to the thread I With gravitational lensing, which way is down?.OK, but then we can immediately discard any possibility that it falls directly towards the star.
-
Dale replied to the thread I With gravitational lensing, which way is down?.I don't know what to do with the "almost" here. If it is almost directly behind then why would you expect that directly towards the star...

's I think Galileo gets the credit for this technique. Newton was born with a year of Galileo's death so he knew of the work I would...

Dale replied to the thread I Topic about physics axioms, theory, laws etc...Then why would you claim that the circulation theory gives correct results? I don't know the theory, but if it says the air needs to go...

Dale replied to the thread I Topic about physics axioms, theory, laws etc...I think that he rolled balls down an incline. I don't know anything about this theory, but if it always gives correct results then what...

Dale replied to the thread I Topic about physics axioms, theory, laws etc...That was from experiment. Now, we consider those experiments so reliable that we have incorporated it into our definition of force...
