Talk:Optics/to do

I think the following definition of optics is more precise. Optics - Physics of light and vision.
 * 1) Reference slow light in either the refraction or dispersion section.
 * 2) Add a Gaussian optics section that explains the thin lens and the mirror equations as a general result.
 * 3) Add information about how the microscope and reflecting telescopes were improved.
 * 4) Add summary paragraph to History section.
 * 5) Mention Faraday in the polarization section.
