Theory

After today's lecture, the professor gave us an analogy on theory. To me, theory is usually a persons' thoughts about an idea that is yet to be proven. But the analogy that the professor gave was comparing how an eyebrow looks like under an electron microscope; which is magnified 50 times, and a cover of a model showing her eyebrows just like how everyone perceives how an eyebrow looks.

And so, the meaning of a theory was that "it shows us things otherwise that we couldn't see". I thought that this was an interesting approach to look at theories, and the more i think about it, the more it makes sense. When the world was made, no one knew how it was made. We believed that the world was made by God (Whichever religion people belonged to), or there will be fancy stories and legends of how the world was made. People didn't have other views toward the issue until Georges Lemaître came proposed an idea that would later become the Big Bang Theory.

Without theories, humans would all be blinded by what they believe only and would be too scared to explore all the other possibilities. Just imagine if today we still believed that the world was flat, then no one would dare to sail the seas and would have never found out that the world is round.
