What was written by Miraja above is a huge problem in Science.
But writers like Asimov, Gould, Dawkins, are all writers
that have done real science. Same for Sagan. Even though
he got a little maudlin at times with the sci fi. Also RIP.

Sagan wrote a great book on what science is and is not
that should be read by all who like the power of logic and
reasoning, "The Demon Haunted World". Of course one could
conclude that the book is terribly flawed, look who recommends it.
