learn about the origins of the fibonacci sequence, its relationship with the golden ratio and common misconceptions about its significance in nature and architecture.
fibonacci numbers are an interesting mathematical idea. although not normally taught in the school curriculum, particularly in lower grades, the prevalence of their appearance in nature and the ease of understanding them makes them an excellent principle for elementary-age children to study.

the fibonacci numbers are the sequence of numbers {f_n}_(n=1)^infty defined by the linear recurrence equation f_n=f_(n-1)+f_(n-2) (1) with f_1=f_2=1. as a result of the definition (1), it is conventional to define f_0=0. the fibonacci numbers for n=1, 2, ... are 1, 1, 2, 3, 5, 8, 13, 21, ... (oeis a000045). fibonacci numbers can be viewed as a particular case of the fibonacci polynomials f_n(x) with f_n=f_n(1). fibonacci numbers are implemented in the wolfram language as fibonacci[n]....

fibonacci sequence, the sequence of numbers 1, 1, 2, 3, 5, 8, 13, 21, …, each of which, after the second, is the sum of the two previous numbers. the numbers of the sequence occur throughout nature, and the ratios between successive terms of the sequence tend to the golden ratio.

leonardo bonacci, better known as fibonacci, has influenced our lives profoundly. at the beginning of the $13^{th}$ century, he introduced the hindu-arabic numeral system to europe. instead of the roman numbers, where i stands for one, v for five, x for ten, and so on, the hindu-arabic numeral system uses position to index magnitude. this leads to much shorter expressions for large numbers.1 while the history of the numerical system is fascinating, this blog post will look at what fibonacci is arguably most well known for: the fibonacci sequence. in particular, we will use ideas from linear algebra to come up with a closed-form expression of the $n^{th}$ fibonacci number2. on our journey to get there, we will also gain some insights about recursion in r.3 the rabbit puzzle in liber abaci, fibonacci poses the following question (paraphrasing): suppose we have two newly-born rabbits, one female and one male. suppose these rabbits produce another pair of female and male rabbits after one month. these newly-born rabbits will, in turn, also mate after one month, producing another pair, and so on. rabbits never die. how many pairs of rabbits exist after one year? the figure below illustrates this process. every point denotes one rabbit pair over time. to indicate that every newborn rabbit pair needs to wait one month before producing new rabbits, rabbits that are not fertile yet are coloured in grey, while rabbits ready to procreate are coloured in red. we can derive a linear recurrence relation that describes the fibonacci sequence. in particular, note that rabbits never die. thus, at time point $n$, all rabbits from time point $n - 1$ carry over. additionally, we know that every fertile rabbit pair will produce a new rabbit pair. however, they have to wait one month, so that the amount of fertile rabbits equals the amount of rabbits at time point $n - 2$. resultingly, the fibonacci sequence {$f_n$}$_{n=1}^{\infty}$ is: [f_n = f_{n-1} + f_{n-2} \enspace ,] for $n \geq 3$ and $f_1 = f_2 = 1$. before we derive a closed-form expression that computes the $n^{th}$ fibonacci number directly, in the next section, we play around with alternative, more straightforward solutions in r. implementation in r we can write a wholly inefficient, but beautiful program to compute the $n^{th}$ fibonacci number: this is the main reason why the hinu-arabic numeral system took over. the belief that it is easier to multiply and divide using hindu-arabic numerals is incorrect. ↩ this blog post is inspired by exercise 16 on p. 161 in linear algebra done right. ↩ i have learned that there is already (very good) ink spilled on this topic, see for example here and here. a nice essay is also this piece by steve strogatz, who, by the way, wrote a wonderful book called sync. he’s also been on sean carroll’s mindscape podcast, listen here. ↩
connections with the fibonacci sequence
the fibonacci sequence is an optional way to describe the scope of work in terms of estimated numerical points. it helps agile teams identify the relative complexity between different backlog items. the sequence of numbers is just one of seemingly endless ways you and your scrum teammates can size pbis, discuss capacity, and coordinate your work.
the fibonacci sequence, in simple terms, says that every number in the fibonacci sequence is the sum of two numbers preceding it in the sequence

this fibonacci calculator will generate a list of fibonacci numbers from start and end values of n. you can also calculate a single number in the fibonacci sequence, fn, for any value of n up to n = -200 to +200
nov 2001 the fibonacci sequence is defined by the property that each number in the sequence is the sum of the previous two numbers; to get started, the first two numbers must be specified, and these are usually taken to be 1 and 1. in mathematical notation, if the sequence is written $(x_0, x_1,x_2,...)$ then the defining relationship is \begin{equation}x_n=x_{n-1}+x_{n-2}\qquad (n=2,3,4...)\end{equation} with starting conditions $x_0=1, x_1=1$.
the more ambiguous the requirement, the more difficult it is to calculate how long something will take. but teams still need to estimate their work to forecast releases. relative sizing provides a realistic method for estimating. ultimately, your team will find their own value scale and their own language that is meaningful to them. until then, these practical fibonacci tips will help kick-start your relative sizing.
