Lithography is about science and technology, making things small to make them better. Like all sciences, the pursuit of truth is cherished above all else. There seems little in common with politics, where truth mostly just gets in the way. And yet, there can be some overlap.
In the fall of 2010, a lithographer in Brazil, Ricardo Vieira, ran for Congress there. He told me, "We don't have any representative from the scientific workers class into our Congress, so I decided to be a candidate." He played up his experience in Nanotechnology to promote his campaign, even creating what might be the world's smallest campaign slogan - "Vote Ricardo Vieira" printed so small that it is completely visible through the eye of a needle.
Here is a pdf collection of his campaign posters. Very interesting (even more so if you speak Portuguese).
