Een Waar Gebeurd Horrorverhaal !
In 1897 probeerde de staat Indiana in Amerika de volgende wet door te voeren. Ongelooflijk, maar waar.
Deze wet is sindsdien bekend als de "Indiana Pi Bill". Dr. Edwin J. Goodman, een arts uit Solitude, Posey County, Indiana was ervan overtuigd dat hij de cirkel gekwadrateerd had, en hij besloot dat de staat Indiana de eerste was die van zijn nieuwe ontdekking mocht profiteren. Zij mochten zijn nieuwe ontdekking gratis op hun scholen gaan gebruiken. De rest van het land en van de wereld zou hem later royalty moeten betalen om zijn ontdekking te mogen gebruiken.

Vooraf was deze wet al door de onderwijscommissie met 67 tegen 0 stemmen aangenomen!
Hier is de volledige tekst van het wetsvoorstel:

 
HOUSE BILL NO. 246

"A bill for an act introducing a new mathematical truth and offered as a contribution to education to be used only by the State of Indiana free of cost by paying any royalties whatever on the same, provided it is accepted and adopted by the official action of the legislature of 1897.

"Section 1. Be it enacted by the General Assembly of the State of Indiana: It has been found that a circular area is to the square on a line equal to the quadrant of the circumference, as the area of an equilateral rectangle is to the square on one side. The diameter employed as the linear unit according to the present rule in computing the circle's area is entirely wrong, as it represents the circles area one and one-fifths times the area of a square whose perimeter is equal to the circumference of the circle. This is because one-fifth of the diameter fils to be represented four times in the circle's circumference. For example: if we multiply the perimeter of a square by one-fourth of any line one-fifth greater than one side, we can, in like manner make the square's area to appear one fifth greater than the fact, as is done by taking the diameter for the linear unit instead of the quadrant of the circle's circumference.

"Section 2. It is impossible to compute the area of a circle on the diameter as the linear unit without trespassing upon the area outside the circle to the extent of including one-fifth more area than is contained within the circle's circumference, because the square on the diameter produces the side of a square which equals nine when the arc of ninety degrees equals eight. By taking the quadrant of the circle's circumference for the linear unit, we fulfill the requirements of both quadrature and rectification of the circle's circumference. Furthermore, it has revealed the ratio of the chord and arc of ninety degrees, which is as seven to eight, and also the ratio of the diagonal and one side of a square which is as ten to seven, disclosing the fourth important fact, that the ratio of the diameter and circumference is as five-fourths to four; and because of these facts and the further fact that the rule in present use fails to work both ways mathematically, it should be discarded as wholly wanting and misleading in its practical applications.

"Section 3. In further proof of the value of the author's proposed contribution to education, and offered as a gift to the State of Indiana, is the fact of his solutions of the trisection of the angle, duplication of the cube and quadrature having been already accepted as contributions to science by the American Mathematical Monthly, the leading exponent of mathematical thought in this country. And be it remembered that these noted problems had been long since given up by scientific bodies as unsolvable mysteries and above man's ability to comprehend."

Brrrrrrr....!!!!
Gelukkig voor Indiana was op 5 februari het hoofd van  de "Purdue University Mathematics Department", professor Waldo, aanwezig om te lobbyen voor een budget voor zijn universiteit. Hij was verbaasd dat er wiskunde werd besproken inde General Assembly. Maar deze verbazing sloeg om in afschuw toen hij ontdekte wat er besproken werd. Die avond  "coachte"" hij de senatoren over de wet. 

Met succes. De wet haalde het niet.......

Niet alleen probeerde Goodman de verkeerde waarde voor p te introduceren; deze "wetenschapper"  had waarschijnlijk zelf niet eens door dat hij ook verschillende waarden voor p beoogde.

Ik citeer uit de tekst hierboven:

 

... " It has been found that a circular area is to the square on a line equal to the quadrant of the circumference, as the area of an equilateral rectangle is to the square on one side..."

Met "equilateral rectangle" wordt natuurlijk gewoon een vierkant bedoeld. Dan staat hier in normale taal:

ofwel       en daaruit volgt gemakkelijk  p = 4

Het volgende citaat uit dezelfde tekst:

... " The diameter employed as the linear unit according to the present rule in computing the circle's area is entirely wrong, as it represents the circles area one and one-fifths times the area of a square whose perimeter is equal to the circumference of the circle...." 

Daar staat dus  p = 1/5 • (oppervlakte van het vierkant waarvan de omtrek hetzelfde is als van de cirkel)

Dat geeft:   

en daaruit volgt  p = 20/6 = 10/3 » 3,333

Op naar de volgende:

..." the ratio of the chord and arc of ninety degrees, which is as seven to eight..."

 

Hier staat eigenlijk:    

en daaruit volgt  p » 3,23

 
Om te laten zien dat Goodman niet alleen van p geen verstand had, maar ook niet van andere wiskunde het volgende citaat:

..." the ratio of the diagonal and one side of a square which is as ten to seven...."


Daaruit volgt en passant dat Ö2/1 = 10/7  ofwel  Ö2 » 1,43

Het laatste citaat dan maar:

..." the ratio of the diameter and circumference is as five-fourths to four..."


daar staat dus  2r/2pr = 1,25/4  Þ  p » 3,2

En zo hebben we vijf blunders in één document.
Typisch DOMMIGHEID!
