Interleaving Of Ideas

Remember old movies had guns with only chamber to fire the bullet, Someone who was working on ships came back and thought merging the steering wheels and guns, And voila Colt revolver.

Cars where made before Ford, but Ford came in and brought assembly line with him.

Phone were made before hand, touch based devices where there but iPhone came in and replace the dial pad with screen.

What came in play in all of these one domains or fields knowledge was taken and applied to other. “Interleaving”.
