Hi Julia Comunity!

I have tried to search almost everywhere and I can not find what is the meaning of the Julia lang logo.  
I’ve found the name “Julia” meaning here [Why is the name of the language "Julia"?](https://discourse.julialang.org/t/why-is-the-name-of-the-language-julia/4382) but no mention about Julia logo,

Do someone here know what is the meaning of Julia Logo? I’m just curious 😃

The four circles represent the four founders of the Julia language: Jeff, Stefan, Alan, and Viral: the “four horsemen of the array-pocalypse”.

(Just kidding - I have no idea.)

I’d venture to say no meaning, just aesthetics… unless each dot represents one of the co-creators 🤔

I read somewhere in the past that the coloured dots represent the different application field that julia users often focus on. Can’t remember where I’ve read it and which colour relates to which field but maybe someone else can chime in here and tell us more about it (or if this hypothesis is completely incorrect after all).

It dates _waaay_ back to some ASCII art [Jeff drew](https://github.com/JuliaLang/julia/commit/f1662b024063d80889a29f757deec82868f8da76). The very same ASCII art that you see upon launching Julia these days. Then my understanding is that Stefan found a nice font (MN Latin) to make the real graphics version. Not sure where the idea for the ∴ dot arrangement came from, but the color palette was limited to terminal colors (see ASCII art above). Also it looks like we’ve taken a square root at some point along the way.

Knowing @jeff.bezanson, he’ll probably add three more apocryphal reasons for the design along with those listed here. 🙂

Some kind of vowel-based code, perhaps…?

Sorry to necro a nearly three-year-old post, but I need you to know that this answer is now the one that Google’s generative AI tool picks up when you search “Julia language logo meaning.”

So I suppose congratulations are in order. In the minds of a select few, this is now the answer.

It always reminds me of those three lovely dots in the calligraphy used in the context of Lord of the Rings or Hobbit 😉 Let’s see if this will ever be picked up by an AI 😜

Btw. it’s interesting that Bard states “I also consulted with experts in the Julia community to verify the accuracy of my information” when asking where the information comes from.

**Here is the response of Bard on the input _“Julia language logo meaning.”_:**

> The Julia language logo is a simple yet elegant design that conveys a sense of power, versatility, and innovation. The main elements of the logo are four circles of different colors, with four smaller colored dots inside each circle.
> 
> The four circles represent the four main pillars of the Julia language:
> 
> 1. **Scientific computing:** The blue circle represents the language’s strengths in scientific computing, data analysis, and numerical simulations.
> 2. **General-purpose programming:** The green circle represents the language’s versatility for general-purpose programming tasks, such as web development, machine learning, and system programming.
> 3. **Interactive programming:** The red circle represents the language’s interactive capabilities, making it easy to experiment and prototype code quickly.
> 4. **High performance:** The purple circle represents the language’s emphasis on performance, making it suitable for demanding applications.
> 
> The four smaller dots inside each circle symbolize the four foundational data types in Julia:
> 
> 1. **Integers:** The orange dot represents integers, which are the basic building blocks of arithmetic operations.
> 2. **Floating-point numbers:** The yellow dot represents floating-point numbers, which are used for representing real-world quantities with precision.
> 3. **Strings:** The purple dot represents strings, which are used for storing and manipulating text data.
> 4. **Functions:** The green dot represents functions, which are the fundamental units of code execution in Julia.
> 
> Together, the four circles and four dots create a cohesive and visually appealing logo that effectively captures the essence of the Julia language: a versatile, powerful, and high-performance language for scientific computing, general-purpose programming, and interactive development.

**Quoting Bard as of 2024-01-23 when asking “_where did you get this information from?_”**

> I gathered the information about the meaning of the Julia language logo from a variety of sources, including:
> 
> - **The official Julia language documentation:** [Julia Documentation · The Julia Language](https://docs.julialang.org/en/v1/)
> - **Discussions on the Julia language community forum:** [What is the meaning behind Julia lang logo?](https://discourse.julialang.org/t/what-is-the-meaning-behind-julia-lang-logo/59274)
> - **Articles and blog posts about the Julia language:** [Introduction to Julia. what, when, why, how | by Adarsh Ms | The Startup | Medium](https://medium.com/swlh/introduction-to-julia-946c242ddac1)

That’s an oddly specific hallucination. I hope one day that these systems start to check their own work…

I can’t remember seeing this color coding anywhere before… My AI (Artistic Interpretation) attempt to reproduce the Julia logo based on that specification is:

 ![Screenshot 2024-01-23 at 14.29.07](https://global.discourse-cdn.com/julialang/original/3X/4/2/4223192654089aef5f998cc219b26af3143ae6d7.png)

which doesn’t work as a good logo, and doesn’t “visually appeal” to me … 🙂

> I also consulted with experts in the Julia community to verify the accuracy…

That’s quite a misleading way of saying “I did a quick search/copy/paste without checking the results”!
