111 Years Ago, Indiana Almost Legislated Pi 379

Posted by kdawson from the squaring-the-circle dept.
I Don't Believe in Imaginary Property writes "On February 5, 1897, 111 years ago today, the Indiana legislature very nearly passed a bill 'introducing a new mathematical truth,' that would have erroneously established pi as the ratio 'five-fourths to four' or 3.2. The story explaining the rationale behind the bill and how they were prevented from legislating it when a real mathematician intervened is quite interesting, because the man who discovered the 'new mathematical truth' wanted to charge royalties, which could have made pi the first form of irrational property."

      Hm... no, you need a process. Those are what all the cool corporations do. Patent the process of "dividing two, common whole numbers for the purpose of usefully approximating the ratio between the diameter and the circumference of a circle". Then make sure the steps described take up at least three pages. Oh and use a lot of impressive sounding words for things. Never say something like "pencil", say "graphite based, portable diagrammatic device rated at two on the graphite integrity scale". Things like that. The USPTO seems really impressed when they haven't the slightest idea what you're talking about.

        The Hebrew alphabet is alphanumeric: each Hebrew letter also has a numerical value and can be used as a number.
        There was an embedded code - a word that was written strangely:

        The common word for circumference is qav. Here, however, the spelling of the word for circumference, qaveh, adds a heh (h).
        ...
        This indicates an adjustment of the ratio 111/ 106, or 31.41509433962 cubits. Assuming that a cubit was 1.5 ft. this 15-foot-wide bowl would have had a circumference of 47.12388980385 feet.
        This Hebrew "code" results in 47.12264150943 feet, or an error of less than 15 thousandths of an inch!
        It gives an error of 0.00265%. Quite remarkable.

          Quite remarkable indeed. One might even call it special pleading.

          The q has a value of 100; the v has a value of 6; thus, the normal spelling would yield a numerical value of 106. The addition of the h, with a value of 5, increases the numerical value to 111.

          Hebrew letters have associated numerical values, that's well known. For the purposes of the argument I'll accept that these letters have the cited values.

          But exactly how did they come up with this particular formula? Given three numbers [A,B,C] what methodology tells them to interpret the combination as the ratio (A+B)/(A+B+C) and not, say, A+B+C or A+B*C, or (A+B)/(A+C)? I don't think there is such a methodology, and I think this means that they will pick whatever formula works for the occasion.

      if we're making bad puns, don't forget the story of Polly Nomial and Curly Pi

      Once upon a time pretty little Polly Nomial was strolling across a field of vectors when she came to the edge of a singularly large matrix.

      Now Polly was convergent and her mother had made it an absolute condition that she must never enter such an array without her brackets on. Poll however, who had changed her variables that morning and was feeling particularly badly behaved, ignored these conditions on the ground that they were unnecessary, and made her way amongst the complex elements.

      Rows and columns enveloped her on both sides. Tangents approached her surface; she became tensor and tensor. Quite suddenly two branches of a hyperbola touched her at a single point. She oscillated violently, lost all sense of directrix and went completely divergent. As she reached a turning point she tripped over a square root which was protruding from the erf and plunged headlong down a steep gradient. When she was differentiated once more she found herself alone, apparently in a non-Euclidian space.

      She was being watched however. That smooth operator, Curly Pi, was lurking inner product. As his eyes devoured her curvilinear co-ordinates, a singular expression crossed his face. Was she still convergent, he wondered. He decided to integrate at once.

      Hearing a vulgar fraction behind her, Polly turned round and saw Curly Pi approaching with his power series extrapolated. She could see at once by his degenerate conic and his dissipative terms that he was bent on no good.

      "Eureka" she gasped.

      "Ho Ho" he said, "what a symmetric little polynomial you are. I can see you're absolutely bubbling over with secs."

      "Oh Sir", she protested, "keep away from me, I haven't got my brackets on."

      "Calm yourself, my dear," said our suave operator, "your fears are purely imaginary."

      "i,i," she thought. "Perhaps he's homogeneous then."

      "What order are you," the brute demanded.

      "Seventeen", replied Polly.

      Curly leered. "I suppose you've never been operated on yet", he said.

      "Of course no," Polly exclaimed indignantly. "I'm absolutely convergent".

      "Come, come," said Curly, "lets off to a decimal place I know and I'll take you to the limit".

      "Never" gasped Polly.

      "EXCHLF" he swore, using the vilest oath he knew. His patience was gone. Coshing her over the coefficient with a log until she was powerless, Curly removed her discontinuities. He started at her significant places and began smoothing her points of inflection. Poor Polly, all was up. She felt his digit tending to her asymptotic limit. Her convergence was gone for ever.

      There was no mercy, for Curly was a Heavyside operator. He integrated by partial fractions. The complex beast even went all the way round and did a contour integration. What an indignity. To be multiply connected at her first integration. Curly went on operating until he was absolutely and completely orthogonal.

      When Polly got home that evening her mother noticed that she was truncated in several places. But it was too late to differentiate now. As the months went by, Polly increased monotonically. Finally, she generated a small but pathological function which left surds all over the place until she was driven to distraction.

      The moral of the story is this: If you want to keep your expressions convergent, never allow them a single degree of freedom.

        Concerned readers of the rather lurid tale above may rest assured that its scandalous contents are entirely false.

        Mr. Pi is a well known and well respected number in the mathematical community, who despite its irrational tendencies, has won the hearts of all decent magnitudes with its transcendental nature. A nature one might add, which intrinsically prevents it from appearing at the roots of any finite order equation, let alone one of only seventeenth order.

        Mr. Pi is a good friend to many highly respected mathematical families such as the Trigonometric Functions and the Elliptic Functions. It is also known for its generous community work, appearing in many Geometrical texts and Physics equations, and in general is known far and wide for not holding itself above the common constant, despite its fame and status.

        Mr. Pi has been known for years as a wonderful role model and teacher for polynomials of a small degree, particularly for second order equations. It has opened up worlds of possibility and inspired these young equations for many years, and it would be a great shame if this false, cruel and libelous fiction caused an end to those efforts.

        I urge readers to reject and condemn this utterly false, malicious and libelous insult upon a good member of the mathematical community. We must not abandon the rigor and scruple that our community is renowned for, and succumb to emotive reasoning. The reader may be assured that however rational their coefficients, seventeenth order equations are known to come across irrational roots, of any multiplicity, all by themselves!

    My favorite part of the bill is the final line, which reads:

    And be it remembered that these noted problems had been long since given up by scientific bodies as insolvable mysteries and above man's ability to comprehend.

    This, along with the rest of the math in the bill, makes it clear that the authors were the sort that only "believe" in rational numbers. Of course, by that time mathematicians already had a pretty good hold on the rest of the real numbers, and there wasn't any mystery at all about the existence of numbers that weren't the ration of two integers. The only real mystery here is why they preferred the approximation 3.2 rather than 3.1. Not that either is good enough for engineers, who routinely used 3 places as the minimal precision if you don't want to be laughed out of the room.

    One of my favorite bits of mathematical humor is the many cases where they have taken criticisms and turned them into terminology. Thus, when it was realized that numbers like e and pi couldn't be written as ratios of integers, there were a lot of dummies who didn't accept this, and attacked the rationality of the people who did. The response of mathematicians was to say, in essence, "Hey, they call us irrational; that's a good word. Let's call the numbers that our critics believe in as 'rational', and the numbers that they don't believe in as 'irrational'. They'll be happy, and we'll have handy words for talking about these two kinds of numbers."

    It happened again when people started talking about square roots of negative numbers (and engineers found practical uses for them in the real world). There were the usual criticisms, to the effect that negative numbers don't have square roots, and it's stupid to talk about things that don't exist. The natural (;-) reaction of the mathematicians was to first be bemused by the very idea that any kind of numbers have any sort of real existence. Then they adopted the critics' words as terminology, with 'real' numbers the sort that the critics accepted, and 'imaginary' numbers the kind that produced negative numbers when multiplied by themselves. That must have really played with the critics' minds. "Oh, you want to talk about real numbers; that's room 12A, just along the corridor. We're talking about imaginary numbers here. Stupid git."

    Of course, there's the even more basic concept of 'natural' numbers, i.e., positive integers. It's clear from most most languages' words for numbers that most people historically have only dealt with this sort of number. Even today, many US high-school kids have a certain resistance to the idea that they have to learn about fractions, which strike them as 'unnatural' and pointless. So mathematicians adopted 'natural' as a subtle jab at the irrational attitude of the ignorant masses.

    At least this bill's authors had enough understanding to accept rational numbers as real, though they classified irrational numbers like pi as "insolvable mysteries". It is sad (and funny) that as late as 1897 this sort of ignorance could actually make an appearance in a legislative body and apparently be taken as anything but a lame joke.

    There have been other bills like this in the past, though as far as I've read, none of them has ever actually been passed, or even voted on. Anyone know of a case where one reached a vote?
