Chemistry? As much as you may not want to admit it, chemistry — particularly organic chemistry, or that branch of the field that focuses on carbon-based molecules — is a crucial starting point for understanding how the human body works. When all is said and done, the universe boils down to two fundamental components: matter, which occupies space and has mass; and energy, or the ability to do work or create change.
