The Oatmeal make some awesome comics and I particularly like this one which features one of the chief scientific badasses of the 19th and 20th centuries – Nikola Tesla.  Tesla is probably most famous for popularising alternating current but anyone who has ever played the Command and Conquer strategy games of the nineties probably remembers his name from the series of electrical weaponry named after him! Born in Serbia, Tesla gained experience in telephony and electrical engineering before emigrating to the United States in 1884 to work for Thomas Edison.
