Prof: Have you ever felt your God, tasted your God, smelt your God? Have you ever had any sensory perception of God for that matter?
Student: No, sir. I'm afraid I haven't.
Prof: Yet you still believe in Him?
Student : Yes.
Prof: According to empirical, testable, demonstrable protocol, science says your GOD doesn't exist. What do you say to that, son?
Student: Nothing. I only have my faith.
Prof: Yes. Faith. And that is the problem science has. Student: Professor, is there such a thing as heat? Prof: Yes.
Student: And is there such a thing as cold? Prof: Yes.
Student : No sir. There isn't. (The lecture theatre becomes very quiet with this turn of events.)
Student: Sir, you can have lots of heat, even more heat, superheat, mega heat, white heat, a little heat or no heat. But we don't have anything called cold. We can hit 458 degrees below zero which is no heat, but we can't go any further after that. There is no such thing as cold. Cold is only a word we use to describe the absence of heat. We cannot measure cold. Heat is energy. Cold is not the opposite of heat, sir, just the absence of it. (There is pin-drop silence in the lecture theatre.)
Student: What about darkness, Professor? Is there such a thing as darkness? Prof: Yes. What is night if there isn't darkness?
