Pulse in a food processor until very finely chopped. Combine milk, flour, salt, pepper and nutmeg in a large saucepan. Cook over medium heat, whisking, until thickened, 2 to 4 minutes. Remove from the heat and stir in half a cup of cheddar, cottage cheese and the spinach.
An aspheric lens or asphere is a lens whose surface profiles are not portions of a sphere or cylinder. In photography, a lens assembly that includes an aspheric element is often called an aspherical lens. The asphere's more complex surface profile can reduce or eliminate spherical aberration and also reduce other optical aberrations such as astigmatism, compared to a simple lens.
The aqua circle is a source as it would be seen if there was no lens; white spots are the multiple images of the source. A gravitational lens is a distribution of matter (such as a cluster of galaxies) between a distant light source and an observer, that is capable of bending the light from the source as the light travels towards the observer.
