It has been only a few months since celebrations were held around the world to mark the 50th anniversary of the first landing of humans on the moon, with Neil Armstrong’s “one small step for man, one giant leap for mankind”. Shortly after pronouncing those historic words, Armstrong, at the peak of his fame, decided to leave NASA. Unlike many fellow astronauts, he did not swap his spacesuit for a seat in Corporate America or in Congress. Instead, he accepted a teaching position as an Engineering professor at university. Whilst we will never know the deep motivations of his choice, it is not unreasonable to think they had something to do with his personality.
