• How Racecar Drivers Use Physics on the Track

Learn how aerodynamics and grip affect a car’s performance in this video from SciTech Now. Automotive experts discuss how repeat testing is done to continually improve a car’s aerodynamics and increase its grip on the racetrack in order to raise the chances of winning a race.

See the Visualizing Airflow Activity in the Supporting Materials section to conduct your own wind tunnel aerodynamics tests.

• The Half-Mile Long Microscope

Learn how scientists turn a half-mile long particle accelerator into a microscope in this video from SciTech Now. Located on Long Island, the National Synchrotron Light Source II is a groundbreaking research facility where electrons are shot around a circular track at nearly the speed of light for various experiments. As X-ray beams from these tests separate off, various researchers’ stations collect them to study microscopic samples of material.

See the Electromagnetic Spectrum All Around Us Handout in the Supporting Materials section to learn more about where x-rays and other types of light are found, and how they're used.

• Defining Gravity: Einstein's Theory of Relativity

Explore how Einstein grappled with the concept of gravity when formulating his Theory of Relativity, in this video from SciTech Now partner World Science Festival. Einstein treated gravity’s effects as a result of accelerated motion, and changing your frame of reference potentially changed everything

• Wind Turbines

In this video from SciTech Now, students learn about an extremely efficient way to harness wind energy for urban environments. Derek Grassman is the innovator behind the wind energy company Kohilo Wind. He was always passionate about clean energy, but it wasn't until Grassman found himself homeless and living in the woods that he was able to turn his ideas into a reality.

• How Many Licks Does It Take to Get to the Center of a Lollipop?

Learn how mathematicians use fluid dynamics to determine how many licks it takes to finish a lollipop in this video from SciTech Now partner Science Friday. The mathematicians make their own lollipops and suspend them in a solution, where they can study how fluid flows around the lollipops, slowly dissolving them. See what ways this method is accurate, and how it differs from an actual lick.

• Ask an Expert: Fracking and Earthquakes

In this video from SciTech Now partner World Science Festival, learn from Columbia University’s Heather Savage how fracking and earthquakes are possibly related. Fracking involves pumping fluid underground in order to force rocks to crack and release gas. If that fluid intersects a fault line, earthquakes can occur.
