Who was Heraclitus?

Have you ever looked at a picture of yourself as a baby and thought, "Is that really me?!" Well, you are not the only one asking that brain-bending question! Travel way back in time to around 500 BCE in the ancient city of Ephesus, where a brilliant philosopher named Heraclitus asked a world-famous puzzle: Can you step into the exact same river twice? He said no! Because water is always flowing, the second you step back in, it's totally different water! But what does a rushing river have to do with you? It turns out, you are constantly changing too! From the thoughts in your brain to the trillions of tiny cells making up your body, you are always replacing your parts like flowing water. Join Mira and Finn as they explore this two-thousand-year-old mystery! Discover why having a bad day doesn't permanently freeze who you are, why change is actually a superpower, and what happened to Heraclitus's lost book. Put on your philosophical thinking caps and get ready to go with the flow!
