Endurance is the key to success
While working on the invention of the incandescent lamp, Edison demonstrated real miracles of endurance - once he did not sleep for 45 hours in a row. The quote about science by A.F. Ioffe is true here: “The problem is solved not by the one who enjoys partial success, but by the researcher who achieves the full result.”
How else did Edison show his persistence in scientific research? It is a well-known fact: the scientist tried about six thousand different materials to find the optimal one for the incandescent filament. In the end, the persistent inventor settled on the most suitable - Japanese bamboo.
