Curious to know how technology and the world around you work? Join us on Zoom for short talks by MIT researchers, with a chance to ask questions after each talk!
The talks are designed for high schoolers and adults with little or no previous background in the topics, but all are welcome. Attendance is free, but registration is required.
“Acoustic Levitation” | Reid Kovacs
Scientists can levitate small objects with sound! Acoustic levitation uses very high-pitched speakers to change the air itself, creating a mid-air pressure pocket for the object to rest in. Different configurations can achieve levitation - some with single speakers, others with many, each with their own benefits and drawbacks. This talk will explore the fundamental concepts and a few of the commonly used methods to achieve acoustic levitation.
“Plastics of the Future: Lessons from The Ocean” | Omar Tantawi
Since their invention in 1950, plastic materials have found applications in nearly every product we use. However, due to their high resistance to degradation in natural environments, plastic products persist for a long time, harming marine life and humans. In this talk, I will discuss how our new plastic degradation testing method yields better results than the state-of-the-art international testing standards. Using this, we can design new smart plastics that can help limit further marine plastic pollution.
"Fast Floating Trains" | Rachel Yang
Some of the fastest trains in the world can reach speeds of 270 mph or more by forgoing traditional motors and wheels. Instead, these trains use a technology called magnetic levitation to hover over a set of tracks as they zip around. But how do these trains work?
This event is the first part of a two-part talk series. If you'd like to register for another Science Snippets event, please visit: https://mit.zoom.us/webinar/register/WN_sGVivj1tRD-5Bv8w0vZdgQ
