Harriet Brooks

Imagine a super-sleuth, but instead of solving mysteries with clues, Harriet Brooks solved mysteries about the tiniest things in the universe: atoms! She was a brilliant scientist from Canada who lived a long time ago. Harriet loved to study something called radioactivity, which is like a special energy that some tiny particles give off.

She was so good at her job that people said she was as amazing as Marie Curie, another famous scientist!

Harriet made some really cool discoveries. She figured out something called 'atomic recoil.' Think of it like when you throw a ball, and you might move back a tiny bit. Atoms can do something similar!

She also discovered that atoms could change into other kinds of atoms, which is called transmutation. It’s like a LEGO brick changing into a different shape all by itself! She was also one of the first people to find a special gas called radon.

Harriet's work helped us understand the world around us much better. By studying radioactivity, she helped scientists learn how atoms work and how they can change. This knowledge is super important for many things we use today, like in medicine and even in making electricity!

She showed everyone that women could be brilliant scientists and make huge contributions to our understanding of the universe.

Harriet's main superpower was her brain! She used her smarts to study radioactivity, which is the energy that comes from the center of atoms. She discovered that when these atoms break apart, they can push themselves away, like a tiny rocket. She also found that one type of atom could turn into another type of atom. This was a huge deal because scientists used to think atoms couldn't change!
