On Metamaterials: Talk With Current Examples by Sabine Hossenfelder

As usual excellent YouTube talk on Physics and Related topics on MetaMaterials.  Notably superlenses and Earthquake cloaking.    The future of material design?

Metamaterials are the next technological stage “after” materials. It’s a research area that has progressed incredibly quickly in the past decade, and that includes superlenses, invisibility cloaks, earthquake protection, and also chocolate. Yes, chocolate. What are metamaterials, and what are they good for? That’s what we’ll talk about today.
