Calculations from chemistry are helpful, but this relies heavily on other areas of astronomy, and somewhat on earth science, with very little on biology. This depends somewhat on physics including mechanics, thermodynamics, electromagnetism, relativity, quantum mechanics, and the structure of matter.	Links to other sites Not yet included.
