HIERACHY OF SYSTEMS IN OUR UNIVERSE Here is the world of truth as I have come to understand it. 1. Logic - The essence of rules of THIS existance. So raw and hardwired, there's almost nothing to say of logic in itself. 2. Math - When one chooses to use units to describe THIS existance, we get math. In and of itself it is the backbone of science. To explain something in science using math is an honor, as 2 + 2 always equals 4. There is no room for question 3. Physics - When applying math to the mass (and none mass) of the universe, we get physics. It is considered the HARDEST science. 4. Chemistry - If one takes physics (and the math that comes with it) and applies it particularly to atoms in terms of joining atoms to form elements, we get chemistry. 5. Biology - When one upgrades the parts of chemistry to the level of molecules that are involved in life, we get Biology. The third of the hard sciences. Beyond this point is a bit open for ideas 6. Ecology - When one takes biology and speaks of it on the level of a population of interacting organisms, we get this wonderful science. So, here's an example. We could speak of the interactions of the cow bird and the oropendola, on terms of their ecological interactions. But, could we not explain this in many more words in terms of their molecules, and how they're proteins are written to so such things? Then could we not take this further and explain it on a elementary level, rather than a molecular level. We could go further, and describe the entire physics of every interaction which causes these organisms to do a particular relation. This would take an enourmous amount of information, but could be done. So you see, each number can be described in incredible detail by the lower numbers. An amazing system! NOTE: Surely some of this beyond the three hardcore sciences is open for debate. My point isn't to say this is truly the ultimate formula, but to share the way I see things, based on my education. Thanks for listening!
