Exploratorium staff physicist Thomas Humphrey reveals why size does matter, at least in physics.

00:22:45
Join Exploratorium Senior Scientist Paul Doherty and visiting scientist Alfredo Mateus for an exploration of hands-on demos. In today's webcast, Paul and Alfredo will be looking at a voice activated chemical reaction and what happens when you heat plastic in water!

TI staff educator Modesto Tamez explains how to make a simple straw oboe that will bring down the house (and teach good physics!)

00:17:30
We speak with glaciologists Slawek Tulaczyk and Jake Walter, who study ice-sheet dynamics.

Invisibility, teleportation, mind reading—the stuff of science fiction, right? Yet much of today’s technology was once considered impossible. Given enough time, couldn’t incredible ideas like these also become commonplace? In this unique presentation, author and physicist Dr. Michio Kaku brings to life the science behind parallel universes and other fantastic phenomena. He’ll discuss the role of nanotechnology in learning to simulate invisibility, explain why NASA envisions sending “nanoships” to the stars, and reveal how nanoscience may provide an escape from the death of the universe itself.

The Exploratorium's Ron Hipschman shows how a double disk with a string attached is a great way to study the physics of motion. Then Captain Yo and Doc Popular astound with amazing yo-yo tricks.

00:26:04
Want to get off the grid but think it’s just too expensive? UCB's Dr. Jeff Grossman explains how nanotechnology may be used to make solar panels cheaper. We’ll also hear from philosopher Patrick Lin of the Nanoethics Group about ethical dilemmas that crop up when we try to improve our lives through nanotechnology.

How do opera singers sing loud enough to be heard over an orchestra? Can an opera singer's voice really break a wine glass? What's the difference between a baritone and a soprano? Discover the answers to these questions—and more!—in this presentation for families. Join physicist and composer Dr. Brian Holmes and San Francisco Opera Center Director Sheri Greenawald to explore how the art and science of singing combine in opera.
