What if you could see inside a medicine and discover its secret building blocks?

The Day Dorothy Hodgkin Saw Penicillin's Secret Shape!

How X-ray detective work helped save millions of lives

Dorothy Hodgkin used X-rays to discover penicillin's secret shape, helping save millions!

Imagine being a detective, but instead of solving crimes, you're solving the mysteries of tiny molecules! That's exactly what Dorothy Hodgkin did on May 12, 1945, when she figured out the exact shape of penicillin.

Wait, what's the big deal about knowing a medicine's shape? Well, here's the thing — penicillin was already saving soldiers' lives during World War II, but nobody knew exactly how it was built! Scientists couldn't make more of it or improve it without knowing its secret structure.

Dorothy used something called X-ray crystallography. She would shine X-rays through tiny crystals of penicillin and study the patterns they made. It was like solving the world's hardest 3D puzzle — with invisible pieces!

This wasn't easy work. There were no computers to help her, so Dorothy had to do thousands of calculations by hand. Can you imagine doing that much math homework? She worked for years, carefully measuring and calculating.

💡 Dorothy Hodgkin did her incredible calculations before computers existed — she used only her brain, pencil, and paper to solve one of science's biggest puzzles!
