Looking the popular view you get tv shows and definitely Prof Brian Cox with his previously life as a pop star with D:Ream. I see things such as the big bang theory being created showing and increase the scientists stereotype, that is they are socially awkward brainy people that are funny to laugh at as they fail to fit in with the world around us. Brain Cox on the other hand has come to previalance because he is the exact opposite, like Richard Feynman he is easy to talk to and has the ability to explain complex ideas with ease for everyone to understand. Now I am not saying we are all like Brian but think of it this way. We wouldn't have science if scientists where unable to communicate.
This then leads me to labels. Prof Cox labels himself a geek, and you could say that those comic book loving social outcasts in big bang are nerds. But really what is the difference. Can you be a nerd, without being geek or vice versa. Interestingly a team that put together a 'Geek Calender' this year, containing snaps of people like Simon Singh and Ben Goldacre, have at the head of their website 'nerds on the march'. This would suggest that a 'nerd' driven movement has created a calender about geeks.
Admittedly these points lead me further from finding the difference between nerd and geek, but more importantly I see the use of the words changing. No longer are people negatively labelled using these words but more using it as an empowerment.
