Hello, tumble listeners, Marshall here.

Lindsay and I are going to be taking this week off for Thanksgiving, where we'll be spending

this week with family, eating food, watching American football, and sharing all of our favorite

facts about dinosaur poop.

I hope all of you who celebrate will be doing something similar.

Since the Thanksgiving holiday is all about being thankful for what you have, we thought

this would be a good opportunity to share a bunch of episodes about scientists who worked

hard to make the world a better place than they found it.

You'll hear about someone who used statistics to help kids escape poverty, another person

who uses engineering skills to develop a better wheelchair after he became disabled, and

two other people who are trying to find new solutions, the problems of plastic trash.

We'll get to those episodes in just a minute, right after this.
