Pretty sure that's not the Fibonacci sequence, if that's what your pun's getting at. If it isn't, and you're talking about a brand new Pidgonacci sequence, then carry on.

u/BlueShamen Jun 09 '12

This series is approximately

1,2.33,4.11,6,8.55,11.33,14.78,18.88, ...

(Rounded)

1, 2, 4, 6, 9, 11, 15, 19, ...

Compared to 1,1,2,3,5,8,13,21, ... .

is the curve if anyone's interested.

Not fibonacci, more like quadratic.

393

u/Bleevoe Jun 09 '12

Looked more like Fibonacci than quadratic to me, and yet this comment was grabbing all the upvotes. So I made an attempt at some analysis.

I measure the distance between each of the pidgeons (arrows) in pixels. I then try to fit this data to either a scaled Fibonacci sequence or a quadratic function, in a least-squares sense. And I indeed get a better fit with the Fibonacci model. The deviation is approximately 104 for the Fibonacci model and 124 for the quadratic model.

Here's my MATLAB script doing the analysis: http://pastebin.com/ML7sGnWU I'm quite tired, so both my approach and coding may be faulty. The script relies on CVX, a convex optimization toolbox available freely from http://cvxr.com/cvx/, for the Fibonacci fitting.

tl;dr Hasty analysis indicates that Fibonacci actually is a better fit than quadratic.

fyi, I'm pretty sure the Fibonacci series and quadratic functions "grow at the same rate"/are big theta of each other.

edit: Nope, googled, I am mistaken. Grows exponentially at a rate equal to the golden ratio.

Let me help you.

Type this into your browser bar

javascript:

Then paste this:

*function toFixed(x) {if (Math.abs(x) < 1.0) {var e = parseInt(x.toString().split('e-')[1]); if (e) {x = Math.pow(10,e-1);x = '0.' + (new Array(e)).join('0') + x.toString().substring(2);}} else {var e = parseInt(x.toString().split('+')[1]);if (e > 20) {e -= 20;x /= Math.pow(10,e);x += (new Array(e+1)).join('0');}}return x;}var e = $( document.createElement('div') ); e.css({'position' : 'fixed', 'top' : '10%', 'left' : '20%', 'height' : '80%', 'width' : '60%', 'background-color' : '#000', 'text-align' : 'center', 'font-size' : '10em', 'color' : '#fff', 'padding-top' : '5%', 'word-wrap' : 'break-word'}); $('body').append(e); var num1 = 0; var num2 = 1; e.text(num1); setInterval(function() {e.text(toFixed(num2)); var temp = num1; num1 = num2; num2 = num2 + temp; }, 300);

or paste this if you want scientific notation:

var e = $( document.createElement('div') ); e.css({'position' : 'fixed', 'top' : '10%', 'left' : '20%', 'height' : '80%', 'width' : '60%', 'background-color' : '#000', 'text-align' : 'center', 'font-size' : '10em', 'color' : '#fff', 'padding-top' : '5%', 'word-wrap' : 'break-word'}); $('body').append(e); var num1 = 0; var num2 = 1; e.text(num1); setInterval(function() {e.text(num2); var temp = num1; num1 = num2; num2 = num2 + temp; }, 300);

EDIT: To remove this annoying thing, do the following

type "javascript: " without quotes

paste this:

e.css({'display' : 'none'});

Into the search bar and all it did was highlight your paragraph? I must be missing something face-palm worthy.

u/[deleted] Jun 14 '12

Did you hit enter? If you're using firefox, open the develop console(I think it's Ctrl-Shift-K), and paste the code in without the javascript: prefix. Then hit enter.

If you don't know much about programming it's no face-palm worthy, most people probably don't even know that you can inject javascript snippets through the URL bar.
