👋 About Me

Tip

This blog was born from the desire to share ideas, experiences, and learning about science, mathematics, and programming with curious and interested people.

My name is Celso Marcellini, I hold a Bachelor’s degree in Mathematics from IME-USP.
Here I explore mathematics, statistics, physics, LaTeX, Quarto, and programming in an accessible and visual way — with good typography, graphics, and reproducible code.

🎨 Beauty as a Criterion (Hardy)

What drives me most is the beauty of ideas in pure mathematics and theoretical physics.
I follow Hardy’s intuition — “beauty is the first test” — and try to show that beauty here is conceptual: natural definitions, concise proofs, and inevitable connections between topics.
Typography and graphics are the wrapping; at the core lies the elegance of the constructions.

💡 About the Blog

🧮 Why Highlight Calculus and Statistics?

Because they are mandatory and essential subjects in most undergraduate courses.
In this blog, this emphasis appears mainly in the courses — with tracks, solved examples, and visualizations to strengthen the foundation that supports the rest.

📚 Editorial Scope

Beyond the courses, articles and series may address any topic in science, mathematics, statistics, computing, and technology.
Editorial commitment: rigor, beauty, and clarity.
There is no place here for hermetic presentations “only for specialists.”

Advanced subjects (for example, differentiable manifolds, Lie groups, quantum field theory, general relativity) do appear here — but always with a clear depth and a solid conceptual foundation.
Superficial expositions often obscure what is, by itself, beautiful and natural; therefore, the idea is to build the foundations that support each concept.

This site was built with Quarto, a tool for creating scientific documents, reports, and static websites using Markdown and LaTeX.

Technologies Used

  • Quarto: rendering .qmd files into HTML
  • RevealJS: interactive presentations
  • MathJax: mathematical formulas
  • AWS S3 or GitHub Pages: static hosting
  • TikZ (exported to PNG/SVG): diagrams
  • Bootstrap theme cosmo + custom styles.scss

General Structure

  • index.qmd: homepage
  • posts/*.qmd: individual posts
  • posts/pessoal/sobre-o-blog.qmd: this “About” page
  • images/: images
  • _quarto.yml: site configuration

🛠️ How This Project Works

📜 Active Scripts

  • atualizar-ultimos-posts.sh
    Generates the list of the most recent posts by date and saves it in a reusable block (e.g., ultimos_posts.qmd).

  • gerar_posts_json.py
    Scans all .qmd files and extracts metadata (title, tags, path) to generate docs/posts.json, used in tag pages and navigation.

  • gerar_tags.py
    Reads posts.json and generates tags_freq.txt, tags.qmd, and lista_tags_gerada.html with the frequency of each tag.

  • nuvem_tags.py
    Creates nuvem_tags.png (a word cloud with tag frequencies), displayed on the tags navigation page.

  • atualizar_tags.sh
    Creates individual pages for each tag (tags/*.qmd), updates tags.qmd with links, and regenerates the word cloud.

  • atualizar_tudo.sh
    Runs everything in order (latest posts → JSON → tags → word cloud), ensuring the site is updated with a single command.
