Science or pseudoscience?

Martin Gardner

The word pseudoscience is defined as follows in the Cambridge Dictionary:

a system of thought or a theory that is not formed in a scientific way

As for Wikipedia, it is defined like this:

statements, beliefs, or practices that claim to be both scientific and factual but are incompatible with the scientific method

We can deduce that pseudoscience is a theory or discipline presented as scientific, but not really scientific. The distinction between science and pseudoscience is important, because there are many pseudosciences, almost more than sciences, although sometimes it is difficult to distinguish them, because throughout history, ideas about what is scientific and what is not, have changed.
