is the sole valid tool to understand the material world.
But its important to be careful of the following:
1- Science can not find absolute solutions. Science itself evolves and finds better solutions.
2- At a particular time several scientists can claim several solutions to problems and for sure some of them might not be valid. This is something to be solved by further research.
3- There exist pseudo-science
not to be confused with science and scientists.
4- Advices of all academicians might not be well compatible scientific methods and you may call them "bad scientists" if you like.
Some knowledge of history of science
would be useful for all and every of us.
But repeating what I initially wrote: Science is the sole valid tool to understand the material world.
No need to try to -again and again- verify the observation of Charles Darwin: "ignorance more frequently begets confidence than does knowledge."
