👋 Hey — you're welcome here too.

For most of history, women who could have been engineers, physicists, and explorers never got the chance — their ideas went unrecorded, their potential unused, simply because of when and where they were born. The women on this site are fictional, but the science is real, and so is the gap they represent.

This site exists to celebrate that brilliance — not to lecture anyone about it. If you're a guy who landed here: the rockets, the robots, the reactors, and the math are all genuinely for you too. Dig into the problems, run the numbers, learn something. We're glad you're here.

All we ask is the same thing we'd ask of anyone walking through a museum: bring some respect for the people — real and imagined — whose work fills the halls.
