# PHILOSOPHIÆ NATURALIS PRINCIPIA MATHEMATICA (Revision IV)

Principia

Revision IV of Newton's amazing work contains everything you need to know about how orbits work, including the formulas in a format that anybody with a basic knowledge of mathematics can understand;

along with discoveries such as; spin theory, the cause of earth's magnetic field, the source of earth's internal heat and explains the true origins of our solar system.

It also explains why Newton was right and Einstein and Bohr were both wrong, and why their errors (that were due to a misinterpretation of Crooke's Tube) eventually led to myths such as the photon, sub-atomic particles, dark matter, black holes, singularity, quantum theory, anti-matter, etc.
