O.K. O.K. O.K. ..... for those reeling from waves of pixelated testosterone after the marvellous men (Darwin Dates, below), here's the oestrogenous counterpart of some wonderful women. Just my personal pick of four who have helped us understand the natural world, whether breaking it down into constituent particles or demonstrating its ecological connectivity at the larger scale - Rosalind Franklin, Marie Curie, Joan Root and Wangari Maathai.
And yes, they all bumped their heads against a glass ceiling but Wangari Maathai at least is living proof of being able to shatter it in this 21st Century. And your top picks from the pantheon of greats.. either sex?
