Physics
The branch of science concerned with the fundamental, most basic rules by which the natural universe exists and operates, from the very small to the very massive, and from the very slow to the very fast. It is the matter and energy that make up the natural world, and the behaviours they depict when interacting.
In theory, the complete knowledge of all physical laws would equate to omniscience - but in practice we must supplement physics with chemistry, biology, psychology, and all other levels of science in order to truly acheive our human goals.
Engineering is concerned with taking the laws of physics (and by extension all other fields of science) to do meaningful things in the real world. If physics is why, then engineering is how. Both being equally important human acheivements.
Discovery, the Scientific Method, and the Human Mind
One the the most wondeful things about human beings is our consciousness. Whether it is the most wonderful is up to interpretation, but considering I would be unable to pose that debate without the consciousness that allowed me to think of it, it is my opinion that it is in fact the most wonderful thing we have ever discovered in the universe to date.
Classical Mechanics
What are Newton's Laws?
Sir Isaac Newton formulated a series of equations which describe the movement of matter at the macroscopic scale - that is, for things that are more or less the same size as us. These "laws" represent some of the earliest physical laws, and while not perfect for the entire scale of matter in the universe, they are extremely useful and have endless practical applications. The formulation of these laws came about during the age of Enlightment, and showed a very important movement towards rationality, the evidence of the senses, and the principles of physical law and the scientific method.
Matter, Electricity, and Magnetism
What is Electricity?
"Electricity" is a somewhat vague term used to refer to the realm of electrons, one of the fundamental building blocks of matter. The electron is a subatomic particle, along with the proton and neutron, which make up the atom. In varying concentrations and quantities, these subatomic building blocks make up the physical world, and their interactions govern many of the laws by which our universe operates.
Electricity can be further subdivided into three areas:
Electrostatics, which is concerned only with stationary, non-moving charges (keep in mind that "movement" is relative, as displacement and therefore velocity
