It's a valid observation. A lens that could somehow do that without moving at all would be pretty magical, and the headline plays on this to get your attention.

It's a valid observation. A lens that could somehow do that without moving at all would be pretty magical, and the headline plays on this to get your attention. The headline could have been "MIT Creates Zoomable Lens That Works Using Heat" which is still cool, but not as sensational.

- cycomanic 6y agoBy this definition of movement absolutely nothing would do anything. If there was electric current you could say, "but the electrons are moving in the material". It's like saying your stove moves when you cook. By any reasonable definition without moving parts means without any macroscopic (mechanical) parts that move.
