How Do Bicycle Pedals Stay On?

August 27, 2020

Ever wonder why the left pedal of a bike has left-handed threads and the right pedal has right-handed threads, yet the pedals stay on when riding?

Modeling a Scatterer Near an Optical Waveguide

August 25, 2020

In the real world, most structures are more complex than a 2D dielectric slab. However, if you’re designing photonic structures, you can learn a lot about wave optics modeling from this example.
