Eventually it will appear on t-shirts. The question of the existence of a 'Secret of the Universe' amount to discovering whether there is some deep principle from which all other knowledge of the physical world follows. Some seekers after the Theory of Everything would seem to be hoping that the uniqueness and completeness of some particular mathematical theory will make it the only logecally consistent description of the world and this will transform it from being a synthetic to an analytic statement. So, today, perhaps the image of the Universe as a computer is just the latest predictable extension of our habit of thought. Tomorrow, there may be a new paradigm.
Science is most at home in attacking problems that require technique rather than insight.
By technique we mean the systematic application of a sequential procedure - a recipe. The fact that this approach to the world so often bears fruit witnesses to the power of generalization. Nature uses the same principle again and again in different situations. The hallmark of these reapplications is their mathematical character. The search for the Theory of Everything is a quest for the technique whose application could decode the message of nature in every circumstance.
