So, today's list is the my top five female nerds and geeks, in no particular order.
Note - on definitions of nerd and geek. I personally consider these positive terms, with nerd applying to people with interests and expertise in scientific areas, and geek to anyone who is very passionate about a particular subject. However, these are just my personal definitions - you may find others online or in a dictionary.
1] Myka Bering - Warehouse 13
Myka is not only super smart, with a great eye for details, but definitely a book nerd. She grew up reading H G Wells and many other classics in the bookshop run by her parents, and her ability to quote Shakespeare has even saved lives.
 Col./Doctor Sam Carter - Stargate SG1
Though she's already turned up on one of my previous top five lists, I couldn't help but include her here. An astrophysicist and engineer, with an obvious passion for science, she is an expert in alien technology and the cleverest member of SG1.
3] Claudia Donovan - Warehouse 13
4] Lisa Simpson - The Simspons
Perhaps one of the most famous nerds/geeks on television, Lisa is years ahead of her classmates. A member of MENSA, she has been interested in astronomy, helped Doctor Nick give her father a heart bypass and in one episode pretended to be a boy so she could learn maths in a more traditional way, after her school was serparated into girls and boys.
5] Doctor Amy Farrah Fowler - The Big Bang Theory
Again another one from my female scientists list. Amy, though not into science-fiction or comics like Sheldon Cooper, is a neurologist with a passion for medieval literature and playing the harp. Probably the smartest out of the Big Bang Theory girls, she seems to have a good knowledge of physics as well as biology.
