It has estimations, approximations and ideal models. It has unknowns, it has infinite possibilities, and every once in a while it has the nulset. I met the nulset alot in high school. More than I should have, unfortunately. But even when you get an approximation or a zero with a slash through it, science can explain itself so that even these entities that couldn't possibly be a feasible solution to anything are now the answer to a complex problem.
Science is wishy-washy.
It keeps on changing its mind about stuff. That's very funny, Science. You're a riot. Not an easy thing to do at first. And why we drive on a parkway and park on a driveway.
