Correction: In this video we state that Jabir ibn Hayyan was Arabian, but there is uncertainty about this among historians. He may have been Persian. Like many influential people of his time, his story is almost mythical, with multiple origins being found in historical writings. 

Also, he never used a Bunsen burner (which is what we erroneously drew him using) that wasn't invented until 1856. Jabir likely burnt wood or other solid fuels to heat his reactions.
