Rather than writing about a specific person, I wrote a blog post on Why Ada Lovelace Day is Important. It includes a review of a thorough study on gender bias among science faculty published a few months ago. It's really distressing to me that even in 2012 there exists this much male privilege in science academia.
Please fix your chart. The origin of the y axis is at 25000 rather than at zero, which makes a 15% difference appear as a 200% difference visually. When comparing two values, proportion is as vital as magnitude.
Today is Ada Lovelace Day, when STEM enthusiasts highlight the work of modern and historical women scientists, engineers, and mathematicians. If you run a blog, you may want to participate by posting about a woman in a STEM field whom you admire. But I'd love to have people share women scientists/mathematicians/authors in the comments that they think we could all stand to read more about.
