While a university professor, famed 17th century English physicist and mathematician Isaac Newton was a notoriously poor speaker. At his first lecture the audience was small, and at his second nobody came. What did Newton do?
Answer: He gave the lecture anyway. He would mostly continue to lecture to an empty room for the next seventeen years. Newton would be subsequently judged to be a genius. whose legacy lives on to the present time. No doubt more enlivening and charismatic lecturers had better attendances, but they are largely forgotten today.
