At times, I would be encouraged by a little unhoped-for success; at others, I would be in the deepest despair because of accidents and failures resulting from my inexperience.

The correct statement of the laws of physics involves some very unfamiliar ideas which require advanced mathematics for their description. Therefore, one needs a considerable amount of preparatory training even to learn what the words mean.

Google the name Prometheus, and see how often it has been given to innovations in many different fields, notably science, medicine and space exploration. The fire he stole can be seen, too, as the spark generating all artistic creativity.
