For more than a century, buttons (and badges and pins) have been carried to signal political or ideological allegiance. The appearance of a button tells us (to use Hegelian jargon) that a group of people an sich is becoming a movement or subculture für sich. If you have a political case to make, then produce a button.
Here’s the first example I’ve found of biomedical buttons. The folks behind easternblot are selling these buttons with the blog’s erlenmeyer flask logo. They are made in two colours — not simply red and blue, of course, but ‘Ponceau S Red’ and ‘Bromophenol Blue’:
Easternblot say they have received “a great response from scientists and non-scientists, from children and adults, from button-fanatics and button-novices”.
A must in any exhibition about the culture of contemporary biomedicine. Can be ordered here (wonder if they give a bulk discount if we would like to fill a whole wall?)
