In the scientific method, what is the difference between Theory, Law, Hypothesis, Conjecture, etc?

Question

Thanks ayoyo_ayoyo. Exactly what I wanted to know. The sequence is:
Conjecture, Hypothesis, Theory, Law

Answer 1

theory is something to be proven/disproven. atomic theory
law is something that describe/model some behaviour.ie. law of gravity.
hypothesis is something to be supported by evidence.
conjecture is something you predict.

so conjecture can become hypothesis then theory then law

Answer 2

Different people use the terms differently, and they are used differently in different instances.

In particular, "theory" often denotes something that's widely accepted as more or less being fact -- e.g., "Theory of Relativity", "String Theory". Or it can be more like a hypothesis -- "I have a theory".

Similarly, a "Hypothesis" can be a lot like a "Conjecture". E.g., the "Continuum Hypothesis".

And given that Newton's Laws were proved wrong by Einstein, the term "Law" isn't used much at all any more.

Nature and Nature's Laws lay hid in night.
God said "Let Newton be!" and all was light.

-- Alexander Pope

It did not last. The Devil shouting "Ho!
Let Einstein be!" restored the status quo.
