Astronomical UnitDid you know in the 1700s astronomers used horizontal parallax to determine accurately the distance between the Sun and the Earth by using Venus traveling across the Sun.
Space TravelDid you know staying in Orbit requires very little energy. Once up to 5 miles a second. The rate of fall (due to gravity) will balance the vector of flying off in a straight line. To return to earth you just need to decelerate.
How cool is trigSine and cosine of an angle defined using the unit circle. Think about that. You can determine every point along that Unit Circle knowing the radius and using Sin and cosine of that angle. (1)
Spherical trigonometryA spherical triangle is a shape created on a sphere's surface by three great circle arcs meeting at each of its three vertices pairwise. A few important facts regarding spherical triangles are: -The sides are not lines; rather, they are the arcs of... See More » (1)
