Java founder, James Gosling, remembers his childhood skiing lessons:
I suppose I could have titled this entry “All I Really Need to Know I Learned while Skiing with my Grandmother”. She didn’t use many words. She wasn’t really into detailed explainations. Just short aphorisms. The interesting thing about aphorisms is that the listener applies a lot of interpretation and can re-apply them. There are three things she said to me over and over again that, while she was talking about skiing, can easily be applied to engineering and life in general:
Balance. I’d come roaring down the hill and she’d yell “Balance, James! Balance!” “Keep your weight centered”. This one echoes through my head every day.
Even if she hadn’t seen me ski down the hill, I’d come up to her and she’d often say “James, you’re breathing too hard. You must be doing something wrong.” If it didn’t look effortless, you hadn’t learned it yet. My engineering reinterpretation of this is essentially the old Blaise Pascal quote: “I apologize for the length of this letter, but I didn’t have time to make it shorter.” Take the time.
The most inscrutable was “Follow your breathing!” When you come skiing down a hill there’s a rhythm to the turns. As you’re making a turn there’s tension in your leg muscles. In between turns, the tension releases. To do it right, you have to coordinate your whole body’s muscle tension. A big part of this is your torso - and in particular the chest muscles involved in breathing. When you take ski lessons they often tell you to breath out when you’re in a turn - this is so that your chest muscles are tense when your leg muscles are tense. Many people end up doing this by seeing when they need to turn, and arranging to breath out then. My grandmother turned this around: she let her body breath at it’s own natural rhythm, and she just turned whenever she exhaled. Listen for the natural rhythms of life and follow them. Go with the flow. When engineering, don’t just come up with some cool technology and jam it in to the solution of some problem. Think about the problem and its context first and let it lead you. Inspiration is 99% Observation.
It was humbling being a 20ish stud wannabee skiing with my 70ish grandmother and realizing that I would never be as graceful and fluid as she was, even at that age.
