There are so many awesome thing about math , but one of the most reassuring is its certainty . If something can be proven – not always a give , we accord you – then it ’s leaven forever ; no going back a few centuries later and realizing you were haywire all alongbecause tit exist .
Take pi , for example . It ’s famouslyirrational , and we are n’t just saying that because we’vecalculated 100 trillion digitsof it so far and the end is still nowhere in pile . The fact – and it is afact – that the constant ca n’t be written as a fraction of two whole numbers has been experience for at least some 360 years at this point : the first have intercourse validation is credited to Johann Heinrich Lambert in 1761 , and at leastfive or six othershave been developed since .
That did n’t seem to matter , though , to nineteenth - century doc and amateur mathematician – stress on the “ amateur ” , there – Edward J Goodwin . It was he who , in 1894 , write a paper that claimed to prove that pi was noetic – and who , three years later , tried to make that lead the law of the land .

The Indiana Pi Bill
And so , in 1897,House Bill No . 246was brought before the Indiana State Legislature .
Be it enact by the General Assembly of the State of Indiana : It has been found that a orbitual area is to the square on a line adequate to the quadrant of the perimeter , as the area of an equilateral rectangle is to the public square on one side . The diam hire as the linear unit of measurement according to the present principle in computing the circle ’s area is whole wrong , as it represents the circle ’s region one and one - fifth times the area of a square whose border is adequate to the perimeter of the circle . This is because one twenty percent of the diam flunk to be represented four multiplication in the circle ’s circumference . For example : if we reproduce the perimeter of a square by one - twenty-five percent of any blood line one - fifth part cracking than one side , we can in like manner make the square ’s arena to appear one - fifth greater than the fact , as is done by taking the diam for the linear unit alternatively of the quadrant of the circle ’s circumference .
It goes on like this for a while – it is , you ’ll be still ( though not surprised ) to hear , fucking folderal from startle to stopping point : as Petr Beckmann noted in hisA History of Pi , it “ not only contradict[s ] elementary geometry , but also appear[s ] to contradict [ itself ] ” – before concluding the proposed human action with a few unauthentic boasts about Goodwin ’s mathematical certificate . Had it passed , the note value of pi would – in Indiana , at least – have been de jure delineate as a rational number .

And the craziest thing of all ? It might have really dumbfound through – had it not been for the fortune intervention of a math prof who knew better .
Squaring the circle
It may have perish down in history as the “ Indiana Pi Bill ” , but the text edition of the pop the question law really never mentions the constant quantity in question . Goodwin ’s title was slightly more circuitous than that : he propose to have found a method of “ squaring the circle ” .
But what does that stand for , exactly ? Well , technically , “ squaring the circle ” is an Ancient Greek problem , but really , it goes back to the very dawn of mathematics – back when all we had going for us as a mintage was ageometry go under and a give ‘ em hell mental attitude . The question is this : given a round of a special area , how do you pull a square with the precise same area ?
It might not sound too difficult when determine out like that , and indeed , the Greeks were pretty good at this “ square ” process when it come to other shapes . As early as 300 BCE , Euclid had already set outan algorithmfor convert a polygonal shape with any turn of sides into a second power with the same area – perhaps , therefore , square up a circle would be a rude development of that process . After all , asat least one ancient philosopher argued , what is a forget me drug if not the ultimate bound of a serial ofn - sided regular convex polygons ?
Sadly for the ancient , though , squaring the R-2 is impossible . How can we be sure ? Well , it turns out that get a way to solve this problem is tantamount to shew that pi is noetic – that , if you were wondering why we have n’t mention it yet , is where the constant quantity in interrogation comes into all of this . you’re able to run through it yourself moderately easily , in reality : the area of a lame of side lengthsiss2 ; the surface area of a circle of radiusris πr2 ; for the two to be adequate , therefore , π would have to be rational .
But pi is n’t justnotrational , it’stranscendental – kind of like the veganism to irrationality ’s vegetarianism . It would take a couple of millennium for that to be proven once and for all – it was eventually close as a problem by Ferdinand von Lindemann in 1882 – but by the time of Goodwin ’s citation - unquote “ resultant role ” , it was a well - established fact .
So what was Goodwin up to ?
Goodwin’s pi
Possibly the weirdest matter of all about the " Indiana Pi Bill " is that , despite being notorious as the visor that tried to legislate a noetic note value for pi , nobody has ever manage to figure out what that economic value was meant to be .
There are some clues : towards the end of the second of three , the bill claims that “ the ratio of the diam and circumference is as five - quarter to four ” , which is equivalent to saying that pi equals 3.2 . That ’s … notbad , as approximations to private detective go – that is to say , it ’s quite a routine less accurate than the Babylonians managed in the17th century BCE , but it’swaybetter than the value implied in segment one of the bill , which at 9.2376 was “ probably [ … ] the self-aggrandizing overrating of π in the history of mathematics , ” Beckmann remark .
In fact , had the bill passed , Goodwin ’s own work would have been outlawed in the body politic . Not that he ever seems to have done anything so ex as to use the correct irrational value of the constant , but a perusal of his various writings turns up at leastnine unlike valuesof pi .
What was he think ? Well , as pointed out byGizmodo , Goodwin was an … interesting lineament . He did n’t rely on frivolous things like “ evidence ” or “ logic ” to support his theorem – he had something better . He knew the on-key note value of sherlock , he explained in an 1897 consultation with The Indianapolis Sun , because God had let out it to him in March 1888 .
Presumably , exactly which of the many values God pinpointed it as has been lost to time .
An unlikely hero
When the Indiana Pi Bill hit the state assembly , nobody was quite sure what to make of it . That ’s not totally surprising , since the notice is essentially 50 percent jargon and 50 pct nonsense – but regrettably , that seems to have been enough to gain over some of the local lawgiver . After being bounced from the House Committee on Canals – no , we do n’t know why either – to the Committee on Education , the bill was passed nem con .
Indiana was one pace closer to have pi lawfully defined as a rational issue discovered by a man who claimed God had recount him the value . It just had to pass the State Senate – which is when the famously named Clarence Abiathar Waldo stepped in .
There was no especial reason Waldo should have jazz about the Pi Bill – he was only in the statehouse that day to lobby for a bigger budget for Purdue University , where he taught math . rather , he found himself witness the State Assembly debating whether to redefine private detective by statute .
Alarmed , he have it upon himself to “ charabanc ” – his words – the senator on the fact of , you know , basic geometry . Thanks to his intervention , when the circular last get hold of the Senate base , it was meet with ridicule .
“ The Senators made bad puns about it , ridiculed it and laugh over it,”reported Will E Edingtonof DePauw University some years subsequently . “ The merriment lasted half an hour . ”
In the end , the Indiana Pi Bill got incisively the regard it deserved : It was indefinitely postponed , as not being a " topic for legislation , ” Edington confirmed .
“ Senator Hubbell characterized the bill as utter folly , ” he indite . “ The Senate might as well strain to pass pee to run uphill as to establish numerical truth by law . ”
