  Einstein was clearly no etymologist

    I can never remember the difference between etymology and entomology and I can’t put into words how much that bugs me.

  Well awktshualy…the definition says reflect, and while diamonds reflect internally, they refract light externally, so, the diamond is not bright because it reflects (those reflections are on the inside) they shine because they refract

    But isn’t their shine mostly due to the internal reflection rather than external refraction? That’s why the gems are cut angularly, to help with the internal reflection.

      You can only observe the external properties since you are on the outside

        By that logic, glass mirrors also work by refraction, because it refracts out of the glass before it reaches your eye.
