Okay kiddo, so you know there are really smart people in the world, right? They spend lots of time studying and doing experiments to learn new things. One group of these really smart people is called the Royal Society.
Now, being part of the Royal Society is pretty cool, but there's an even cooler group within it called the Royal Fellows. These are the smartest of the smart people in the Royal Society.
They're so smart that they get to be part of a special club where they can talk to other super smart people and work on even bigger and cooler projects together.
Being a Royal Fellow is kind of like being a superhero with a cool team of other superheroes to work with!
