Every time I come home from college, he has a new problem for me to fix on his computer. He will fiddle and fiddle with a program until he is befuddled. Usually it is because he missed a step somewhere. If I show him and write down steps, he takes the information I've given him and works it out for himself. Even though the computer's parts are more complex than a carburetor or gear drives, the skills my grandfather used to put it together came from decades of tinkering with machines. He still uses a step-by-step thinking process used in mechanical arts to figure out software and basic functions like e-mail and Internet browsing.
