How do you know that you know what you know?

Jason Kucker from the Nový PORG gymnázium a základní škola in Prague was the guest speaker at our club meeting. Jason's lecture challenged some fundamentals of knowledge and started with a provocative statement: The Greeks were invented by some academics in the 1960's - discuss! Members and friends joined in a lively debate challenging perceptions and assertions which proved precisely the point that knowledge is not a universal truth.  The members and Friends thanked Jason for an interesting, challenging and informative presentation.
