Tutto quello che devi sapere sulla sequenza di Fibonacci
Cos'è la sequenza di Fibonacci?
La sequenza di Fibonacci è una successione di numeri interi in cui ogni elemento è la somma dei due precedenti: 0, 1, 1, 2, 3, 5, 8, 13, 21... Introdotta da Leonardo Fibonacci nel 1202, appare spesso in natura (spirali di conchiglie, disposizione dei petali, rami degli alberi).
Cos'è il numero aureo (rapporto φ)?
Il rapporto tra due termini consecutivi della sequenza di Fibonacci converge al numero aureo φ ≈ 1.6180339887. Questo rapporto è considerato esteticamente piacevole ed è usato in architettura, arte e design. La spirale aurea (basata su rettangoli aurei) è strettamente correlata a Fibonacci.
La sequenza di Fibonacci ha applicazioni pratiche?
Sì! In informatica è usata in algoritmi di ricerca (heap di Fibonacci), compressione e pseudorandomicità. In finanza con le "ritracciature di Fibonacci" nell'analisi tecnica. In natura descrive la crescita a spirale di molti organismi. Nei test software si usano i numeri di Fibonacci come stima degli story point.
What is the Fibonacci sequence?
A series of whole numbers where each one is the sum of the two before it: 0, 1, 1, 2, 3, 5, 8, 13, 21. Leonardo Fibonacci introduced it in 1202, and it turns up in shell spirals and the arrangement of petals.
What is the golden ratio?
The ratio between two consecutive terms of the sequence closes in on roughly 1.618, the golden ratio. It is widely used in architecture, art and design, and the golden spiral is built from the rectangles it produces.
Does the sequence have any practical use?
Yes. In computing it shows up in Fibonacci heaps and in search algorithms, in technical analysis as retracement levels, and in software estimation, where story points are often given as Fibonacci numbers.
Does my data stay private?
Yes, and not because we promise it: this tool runs entirely inside your browser. What you type or upload never leaves your device, so it never reaches a server of ours and there is nothing we could keep, read or lose. You can check it yourself: open the page, disconnect from the internet, and the tool keeps working.
Do you store what I enter?
No. There is no database behind this tool: we do not store your files, your text or your results. When you close the tab nothing is left — not here with us, because it never arrived, and not anywhere else.
Do you profile me? Are you GDPR compliant?
We do not profile you: there is no account to create, we never ask for your email to use a tool, and we keep no profile of what you do. We are an Italian company and we work under the GDPR and the other European rules, with the privacy notice and the consent request in plain sight. One thing we say in full rather than hiding it behind a slogan: the ads on the page are Google's, and Google may use cookies to personalise them. You decide from the consent banner: if you say no the ads stay, but they are not personalised, and the tool works exactly the same.
If it is free, how do you make money?
From the ads on the page, and that is all. We do not sell your data, there is no hidden paid plan, there is no limit that eventually asks for your card, and you do not have to sign up. The ads pay for the servers and for the time we spend writing the tools: that is how we can keep them open to everyone.
