Chemistry is the science of substances, specifically the combination of elements to make other elements. Mass-energy is never created or destroyed, and everything can be explained in terms of physics, no one knows this better than a chemist. In the days before modern science, chemistry was called alchemy and it was the study of the classical elements earth, wind, water, and fire. Today we know the four forces are electromagnetic, gravitational, strong, force, and weak force. We understand these forces create the atoms, that create the elements, that create the molecules, that create the world around us. With great power comes great responsibility.
We explain how to lose body fat from a scientific standpoint, and offer simple science-based advice on dieting, weight loss, and exercise.
The Bohr model of the atom (1913), the one that looks like a solar system, has been replaced by the more accurate Quantum Model of the atom since 1927.
