Lesson 6) How to Find the A.M.E. Components

Chapter 6

In the past, witches and wizards used magical tools like the von Rheticus telescope to find the components of the A.M.E. Quotient
Muggles have made more progress in telescope making, with their best telescopes being far superior to magical ones
Muggle telescopes can make more accurate measurements of angular size, phase, optical albedo, and distance from the Sun
The magical world has made some progress in telescope design, but the newer models are expensive and not available to First Year students
Von Rheticus calculated the distance of planets from the Sun based on their motion in the sky, assuming circular orbits
The distance entered for each planet was the average distance, as the orbits of most planets are close to being circles
The exact distance of a planet from the Sun at any specific time can be calculated using advanced methods discovered by Isaac Newton.
Muggles have more accurate measurements of angular size, phase, and optical albedo of celestial bodies
The von Rheticus telescope has a button labeled "S" for measuring angular size
The telescope calculates the angular size by measuring the magnified object and dividing by the magnification
The telescope calculates the phase of an object by measuring its angular length and width and dividing the width by the length
The von Rheticus telescope has a button labeled "A" for measuring optical albedo
Albedo is harder to measure than angular size
The magical albedo of most surfaces is the same as the optical albedo, but rocky surfaces reflect less magic and water absorbs even more magic
The newest version of the von Rheticus telescope can detect the amount of magic coming from a celestial object and calculate the A.M.E. Quotient
