Binary Star Simulator app for iPhone and iPad

About
an open source physics at Singapore simulation based on codes written by Anne Cox, Wolfgang Christian and Francisco Esquembre and Loo Kang WEE.

Introduction
Gravitation is a natural phenomenon by which physical bodies attract each other due to their masses. This force occurs whenever masses are present and the two bodies need not to be in contact with each other. It is however the weakest of the fundamental forces of nature.
In 1687, Sir Isaac Newton concluded that this non-contact gravitational force must be as responsible for the falling of the apple from a tree as it is the cause for the rotation of the Moon about the Earth. Hence he published the Newton’s law of gravitation which states that:
“The mutual force of attraction between any two point masses is directly proportional to the product of their masses and inversely proportional to the square of the separation between their centres.”


Interesting Fact
This app produce real numbers to coincident with the real world data.
