The New Sabbath Equation – Guest Blog by Luke Murphy

Not many laws of physics can improve your life. This one can:

The coefficient of static friction is greater than the coefficient of dynamic friction.*

What this means is: it takes more effort to start something moving than to keep it moving.

If you’re pushing a car, the heart attack will come during those first furious shoves while you’re trying to make it start rolling. At that stage, your enemy is the coefficient of static friction. As soon as the wheels are turning, you can amble down the street, pushing the car before you while calling out cheery greetings to passers by. Why? Because now you’re working against dynamic friction, a puny force by comparison.

So it is with anything we do: the hard part is overcoming the inertia of an object at rest, which means getting off the couch and committing to the job.Once you’ve defeated the fridge-sized fire-breathing lizard that is the Coefficient of Static Friction, his cousin, the Coefficient of Dynamic Friction, will seem like a sleepy gecko on a hot day. Coefficient of Static Friction

The New Sabbath Project is about building community by having people over for dinner. Putting on a dinner is one of those things like working out regularly, reading Moby Dick, or writing the blog post that you’ve promised: you know you ought to do it but today’s not ideal, maybe when the weather improves, we don’t have enough plates, etc etc. Those excuses are the Coefficient of Static Friction sitting on your chest, his scaly haunches pressing you into the couch.

Static Friction likes you to keep things theoretical, aspirational, potential – anything other than real. Static Friction cannot be reasoned with, bargained with, or met half way. He has to be pushed aside and flung into the dark corner where you lost the battery cover for the remote. His greatest fear is action.

Any physical action will give you the strength to raise Static Friction’s leaden lizard loins from off your wheezing chest. When you know you need to put on a dinner – not a theoretical some-day-we-must dinner, but a real event with real people – the best first step is to email or phone your first choice of guests and ask them. At that point, you can’t go back on it without faking a medical emergency, family tragedy or house fire, all of which will demand more effort than simply putting on a dinner. Yes, the Coefficient of Dynamic Friction – gecko-sized cousin of Static Friction, you recall – will nip at your heels and make hissing noises, but Dynamic Friction is, contrary to his name, lazy by nature and easy to ignore.

Host a dinner. Invite a combination of friends and newcomers. Ask the guests to bring some food: it’s less work and less cost for you and gives them something to take pride in. Repeat, whenever you can. Our heroic hosts Ralph and Cortney do this every week; you don’t have to.

And one odd characteristic of the Coefficient of Static Friction: he gets lighter the more often you fling him off your chest. That part is not explained by physics.
*It’s not actually a law, more of a rule of thumb. There are three laws related to friction, Amonton’s First and Second Laws and Coulomb’s Law. They state, more or less: (i) the heavier you are, the harder it is to get off the couch; (ii) it doesn’t matter whether you’re lying on the couch or have one buttock on the arm rest, you’re still stuck on the couch; and (iii) once you’ve got off the couch and started moving, it won’t get any harder (or easier) to keep moving.
