A listener named Jonathon McIntosh had this comment about my use of the word theory:
In your last podcast, you said you had "just a theory." A theory is tantamount to fact. What you were doing is speculating. Please don't spread this misuse of the word theory. It is an important distinction.
Saying "just a theory" devalues the excruciating hard work of many scientists. Gravity, for example, is "just a theory".
As a former scientist, I know exactly what he means!
Watch the video to hear Ask Science, Dr. Lee Falin and me discuss words such as theory, significant, organic, and positive feedback that mean something different from what you may expect when you talk to a scientist.
