Ever heard of dihydrogen monoxide?
Oh yeah, I use it in the lab every day! I swear its good for everything, some people even call it the "universal solvent". Watch out though, too much of it will kill you! Actually though; dihydrogen monoxide is water. Anything can sound scary if a chemist gets ahold of it. Chemistry has its own language, one made to be as precise as possible at the cost of sounding a bit intimidating. Pretty much the entire universe can be understood by breaking it into atoms. Chemistry is the study of how these atoms interact and how to use that knowledge to understand and change the world around us. Some of these interactions are simple, some more complex, but the beauty of it all is that the interactions of only around 100 elements make up everything you see, hear, smell, touch, and taste.
What do ferns, feelings, and fungi have in common?
Well, actually a lot of things! To name a few; DNA, natural selection and (as far as we know) Earth. Biology is the study of organic systems. The diversity of life is remarkable, but it turns out that all of life has a host of things in common. Biological systems (organisms) reproduce or make more of themselves by copying instructions held in DNA (or RNA in some cases). That replication happens in a game called evolution in which the fittest copy reproduces the most. All of this happens on a very small stage we call Earth. Ferns, feelings, and fungi all evolved as a product of this game, on this stage and through these means. Now, the study of biology is much more in-depth than this, but if you keep this in mind, I promise it all makes sense. You may even learn something about your self along the way! After all, biology is the study of things like you.
What is Algebra?
Algebra is a technique used to solve for something you do not know, by using what you do know. We do this every day whether we are trying to figure out how many invitations we have left to hand out to friends versus how many we have yet to make, or how many slices to cut a pizza into. Algebra is a system by which we can determine these kinds of simple problems all the way up to whether it will rain today or how much fuel our rocket ship will burn on the way to the moon. We do this by reducing the world into X and Y, positive and negative, even imaginary and real; but there is nothing imaginary about it! A system of equations may seem trivial, Evan meaningless, but the power of algebra; the power of mathematics, is that it can help make sense of senseless things.
