Genders of science

A little while ago I saw a call for an exhibition celebrating 'woman' and it got me thinking about what I would have made. Contemplating the genders associated with the three sciences (physics, chemistry & biology) I came up with the spheres above representing the sun & moon (physics), gold & silver (chemistry) and male &  female cells with there chromosomes painted within (biology). Each of these things has been historically  associated with a particular gender or generates that gender.
