      [​IMG]The public: not a clue about engineering?
      ...is a quote from this article about women and technology and why women don't want to be "geeks". I think it illustrates how in the UK there's a real distorted view of what engineering is. There are some non-technical people in the past I've attempted to explain what I do to, but they just don't "get" it. Amazing the amount of ignorance really.
