Dispersion & Refraction in Optics
When white light passes through a prism it spreads out into all the colors of the rainbow. Physics tells us this results from refraction and dispersion.

Reflection of Light in Optics
When light is reflected the incident and reflected angles are equal. Specular reflection is from a smooth surface, and diffuse reflection from a rough surface.

OUR black hole. Part II
It seems that every galaxy harbors a black hole in its core. The larger the central bulge of older stars, the bigger the hole. Our Milky Way is no exception, but only recently have we developed techniques suitable for peering into the cocoon and measuring the massive, quiet beast lurking inside.

Black holes ain't that black then?
That black holes are a pain in the neck for astrophysicists is more or less well known. Infinites and zeroes are fine for mathematics but not to be found in Nature, yet a black hole in principle hides an infinite at its center, or that was accepted until now.
