... stars, all of which formed at roughly the same time so they can serve as cosmic clocks The fate of every star depends solely on its initial mass. So what should we look for (Corpses of massive or light stars)? The brightest of white dwarfs is no more luminous than a 100 watt light bulb seen at the m ...

The Eye and Vision
... The axons of the retinal neurons leave the eyes to form the optic nerves. Just anterior to the pituitary gland, these nerves give rise to the X-shaped optic chiasma, and within the chiasma, some of the fibers cross over. The fibers from the nasal (medial) half of each retina cross over, but those fr ...
