Refraction of Light
In this video Paul Andersen explains how light can be refracted, or bent, as it moves from one medium to another. The amount of refraction is determined by the angle of incidence and the index of refraction. Snell's Law can be used to...

The Reality of Work Requirements for Medicaid
We’ve spent the last few weeks talking work requirements for safety net programs, and it’s all been leading up to this: work requirements for Medicaid. By looking at the EITC and TANF, we learned some things. Can these lessons inform...
