It's so easy to absorb 'celebrity' gossip, I always wondered if it'd be possible to do the same with say science or maths, if it was presented in the same kind of format.

I think the hardest part is the rigour. Math and science build on concepts over time, and mastery is easier with more hands-on experience. Just presenting it to someone in a feed might be waaay too passive for absorption.

Easy way to find out. Remove the pictures from celebrity gossip posts, and see how much you remember.
