Quote by William H. McCallum
"Courage is not the absence of fear, but action despite it."
"Courage is not the absence of fear, but action despite it."
"Mathematics is not about numbers, equations, computations, or algorithms: it is about understanding."
"The best way to understand something is to try to explain it to someone else."
"A good teacher is like a candle - it consumes itself to light the way for others."
"In mathematics, you don't understand things. You just get used to them."
