Hello and welcome back to the Curious Kid podcast. We recorded an episode a long time ago,

in August of 2019, to be exact, and it was one of my favorite episodes. It was called Curious

About Time. We learned all about time. For example, we learned why there are 60 seconds in a minute and 60 minutes in an hour. What's so magical about the number 60? It's easy to take time for granted because it is such a part of our everyday lives. But we didn't always have a convenient way to measure time.

I encourage you to check out that episode because it's super interesting.

Over three years later, we're going to cover another topic that, like time, is just such a

big part of our lives. It's hard to imagine that there was ever a time when it didn't exist.

Dear Jacob and Olivia, we love your podcast. Our names are Livy, eight years old, and Charlotte, five years

old. And we are from Dead of Massachusetts. We listen to your podcast when we are in the car,

and we love learning new things. We have listens to almost every episode. The question of the

week is our favorite part. We have three questions for you. One, can you have the same dream or

nightmare more than once? Two, where do numbers come from? Three, where do letters come from? Thank you for

everything you do. We are so curious. From Livy, Charlotte, and Kate, their mom. Hi, I'm Oliver from

North Beach, Maryland. I'm four years old. I want to learn about numbers and who invented math. Thanks,
