Science works on the simple principle of observation, experimentation and conclusion. But, is everything observable and mesurable in this universe. What about those things that might be beyond our senses.(Say if we lack a sixth sense.) The question came to my mind when I asked myself a question "If humans were blind?" Will we have ever been able to know that there is something like light? The world is not merely measurable. Most of the attributes of this world are subjective and non measurerable. Can science measure beauty?
