How Big is the Solar System? | It's Okay to be Smart | PBS Digital Studios
I took a trip to one of Austin's famous moontowers so I could put the enormity of our solar system into perspective. With the help of a grapefruit, and a lot of walking, you'll get an idea of just how tiny everything is out there!!

Dorothy went over one. LeVar Burton read to us under one. In a song, Kermit the Frog connected us to one. Even Mork's suspenders were made of them.
Pay Attention! | It's Okay to be Smart | PBS Digital Studios
It seems like every week someone tells us how the internet and the digital age are overloading our brains. Sure, sometimes it feels like we're being fed more information than we can handle, that we're paying attention to the wrong things. Are we giving our brain a fair shot?

There is no sound in space. In the near-vacuum of space, there is nothing to transmit the physical waves that we need to perceive sound. But that doesn't mean we can't MAKE sound from space. This week, I feature several artists using scientific data to create "space sonification" projects. From the longest palindrome ever created to a chorus created from Earth's magnetic field, these pieces lie at the intersection of art and science. More than just art, they allow us to perceive patterns in complex data in a completely new way.
Why Music Moves Us | It's Okay to be Smart | PBS Digital Studios
Why does music make us feel happy or sad? Or angry or romantic? How can simple sound waves cause so much emotion? I went from my comfy chair to the streets of Austin to investigate how it might be written into our neuroscience and evolution. Modern neuroscience says our brains may be wired to pick certain emotions out of music because they remind us of how people move!
