gollark: True engineers approximate the pendulum time period formula $T=2\pi \sqrt{\frac{l}{g}}$ as $T=2\sqrt{l}$.
gollark: So basically just "optics but we are HIGHLY engineer-like and use the small angle approximation".
gollark: According to Wikipedia, which I just checked, which makes me an expert,> Gaussian optics is a technique in geometrical optics that describes the behaviour of light rays in optical systems by using the paraxial approximation, in which only rays which make small angles with the optical axis of the system are considered. In this approximation, trigonometric functions can be expressed as linear functions of the angles. Gaussian optics applies to systems in which all the optical surfaces are either flat or are portions of a sphere. In this case, simple explicit formulae can be given for parameters of an imaging system such as focal length, magnification and brightness, in terms of the geometrical shapes and material properties of the constituent elements.
gollark: Fearsome.
gollark: Is this some kind of accursed statistics thing?
