What does it take to destroy a scientific law?
one counter example.
name in order the steps of scientic method
Make observation, form a hypothesis, preform experiments to confirm hypothesis, hypothesis is now a theory, perform many experiments over several years, theory is now a law.
If a hypothesis does not agree with an experiment what are your two choices?
discard hypothesis or modify it to become consistent with data
Why was the theory of superconductors so startling to scientists?
a generally accepted scientific theory said it was impossible to have high temperature superconductors
what are the three limitations of science?
