Ross may have been a scientist with a fossil fascination but over the ten year we never really learnt anything about the rocks that he held so dear. Hed occasionally try to lecture his friends but theyd just mock him before he could say anything interesting and insightful. Of course, this worked really well and was definitely funny. But its great that whilst watching TBBT, we get to learn something. And its still really funny. Sheldon is constantly raving about certain scientific theories and finds any opportunity to impart his knowledge to his friends. He even has a web-series called Dr. Sheldon Cooper Presents Fun With Flags, where, whilst laughing at his classic mannerisms, awkward acting and the jokes that come firing at us, we do actually learn a little about flags. The best thing about this intelligent and hilarious show is that it counts as revision for any up-coming science exams that anyone may have all of the science is accurate thanks to David Saltzberg and Mayim Bialik who both have Ph.Ds and ensure that even the whiteboards in Sheldon and Leonards apartment are scientifically correct.
