“In theory, theory and practice are the same. In practice, they are not.”

This quote is from the genius, Albert Einstein.  It got me thinking why do we spend that much time worrying about theory, if its concepts never really seem to fit in real life.
Truth is, reality is complicated, and we try to understand it piece by piece. The pieces alone don’t really portrait reality, but it might give us a clue about the forces guiding certain events.
The other very important issue on the matter is the fact that we still don’t know everything.  We probably never will. Science,  just like us, is just trying to find its way into comprehending the world we live in. Sometimes it makes mistakes, sometimes it takes the wrong path, but that is just part of learning. On the book I previously recommended,  “The Half Life of Facts”, the author goes through all things we used to believe in, and turned out to be false. Should we stop trying? I don’t think so. The world is too great and awesome for us to just stand here and accept the fact that we can’t understand it. We owe it to ourselves to at least try to figure it out.
