Re: Experience
The grey hairs bring experience to the table.
Exactly. Although not anything I think IBM would be involved in, I recently had to explain to a youngster how to join a gear train to a stepper motor, when said motor had no keyway. In spite of an MSc (Hons) in Aeronautical Engineering, he had never heard of a collet.
Later he decided he needed repeated accelerating rotation for part of his project and started writing a special driver for the stepper before realising that changing the motor speed would change the speed of the entire mechanism, and he was about to abandon his project. I pointed out that all he needed was a spiral gear (nautilus gear). Again he did not believe that such a thing existed as he believed that all gears were circular and that only the tooth shape changed depending on the application.
Mind you he has already gone on to become a millionaire, sold his company, and is now in the process of building up his second business venture. He may have been dangerous to let loose on aeroplane design, but he certainly learnt the lessons of how to do business.
