# A personality quiz for fans of math and history: Are you a Newton or a Leibniz ?, Ars Technica

## Newton and Leibniz are like night and day, or derivatives and integrals.              Jennifer Ouellette    –Nov 10, (6: 36 PM UTC

Math teacher Ben Orlin writes and draws the (aptly named) blog Math With Drawings and is the author of a new book,Change is the Only Constant: The Wisdom of Calculus in a Madcap World. To mark its publication, he devised this entertaining accompanying quiz. You can read the Ars interview with Orlinhere.

Isaac Newton and Gottfried Leibniz have a lot in common. Birthdates in the 1640 s. Fatherless childhoods. Colossal egos. Show-stopping wigs. Most of all, each had the honor of bringing calculus into the world. But when it comes to personalities, Newton and Leibniz are like night and day, or England and France, or derivatives and integrals. They’re rivals. Opposites, even. Do you belong on #TeamNewton or #TeamLeibniz? Take this quiz to find out!

## RESULTS:

If you answered mostly A’s, then congratulations: you are aLEIBNIZ!

You are a polymath, a renowned scholar, and one of those philosophers who loves to tell everybody how important it is to do philosophy. You’re not perfect — one time, you wrote in a think-piece that we live in “the best of all possible worlds,” an argument that Twitter nobodies are still dunking on 300 years later — but in general, your thinking is rich, bold, and abstract. You write beautifully and love to share ideas. You have a profound faith in collaboration and the impartial search for truth.

Unfortunately, you suck at academic knife-fights. Too naïve; too optimistic. Case in point: in your dispute with Isaac Newton, you accepted the British Royal Society as an impartial mediator, despite knowing that its leader at the time was literally Isaac Newton. Oh well. Your strategic stupidity may cost you in the short term. But sooner or later, history will appreciate your genius.

If you answered mostly B’s, then congratulations: you are a (NEWTON) !

You are viewed as an intimidating and extraordinary genius. Renowned poets are constantly dropping laudatory verses about you. Even when we know you’re wrong — like when you spent decades on crackpot theories of alchemy — we’re too awed to give you crap about it. You can also become, when the occasion demands, a stone-cold bitch. You refuse to lose any dispute, and you make quick knifework of your rivals (or, better yet, you have your loyal allies do the dirty work for you).

Is this ego run amok? Sure, in part. But it’s also single-mindedness. You’re not here to make friends; you’re here to solve problems and kick ass. It’s frustrating when “little baiters and smatterers” (your phrase, not mine) come pestering you with questions, or — even worse — trying to claim credit. You just want to think your thoughts. And even your rivals must admit: You think some darn good thoughts.

If you answered mostly C’s, then congratulations: you areONE OF THE MANY NAMELESS OTHERS WHO CONTRIBUTED TO THE DEVELOPMENT OF CALCULUS!

You lay the foundations for the Newtons and the Leibnizes. Or perhaps you extend and elaborate on their work. Or perhaps you solve the same problems, but in a different place, at a different time, as part of a different tradition. In any case, you’re a vital part of the history. Part of the history — yet not part of the story. A few heroes get starring roles; you get left on the cutting room floor. They get lionized; you get lost.

But hey, don’t let the cult of celebrity get you down. Calculus is yours as much as theirs. Ideas (like the ones that comprise calculus) are neither pure nor absolute. They draw their hues and shades from the intellectual context, the way crystals draw their color from trace elements. Each time a new person grasps calculus, something novel and irreproducible emerges; in short, calculus is discovered all over again.
