"Unknowable truth" Over the past two or so years, I have experienced something that I cannot explain: the power of music. Most of us know that all music is just pulses of pressure in the air. But why does it have as much power over the thoughts and emotions of humans? How can these simple pressure systems move masses people to tears? Upon asking my proffessor these questions, he told me that I was asking a question that is unknowable, but that in persuing so, I am unveiling true knowledge. To be honest, I do not understand his words. As a musician this power of music is just a power I respect, as I would 12 M HCl in a laboratory; but as a scientist, it is something I do not understand. Does anyone have an answer to my "unknowable question?"
