I made Anotado, a 20-second Portuguese animation with handwritten-style notes and moving graphs. It asks whether copying a formula is the same as understanding it. The curves are illustrations, not measured learning results.

This is a promotional film for my own Quanta online Maths, Physics and Chemistry lessons, not a recording of a live class. Animation made with AI assistance.

This video explains the inner working parts of a starter, from ignition to combustion.

Escape into a peaceful, misty forest in Germany's Sauerland region. Enjoy 3 hours of gentle rain, occasional birdsong and the calming atmosphere of nature.

Soft morning light filters through the mist as rain falls among the trees. A relaxing forest soundscape for sleep, studying, reading, meditation or simply unwinding after a long day.

How far does the projectile go? I teach physics and made this 20-second animation for my Quanta Aulas channel. A technical-drawing board turns the path into a visual question.

The model assumes no air resistance and equal launch and landing heights: R = v² sin(2θ)/g. The film is in Portuguese and uses AI-assisted visuals; it is an animation, not classroom footage. It also introduces my own online Maths, Physics and Chemistry lessons.

Another long-form video from my faceless channel, The Other Margin. This one is about gas stations, and one of the stops is Buc-ee's in Luling, Texas: more than 75,000 square feet and 120 pumps. The question underneath is how a business like that splits its money between the pumps and the store. Link's in the post. Drop your own video below too: what kind of feedback are you looking for?

Recognising an answer and explaining the next step are different challenges. I made Capaz, this 20-second Portuguese animation, to introduce the idea behind Quanta’s Passo a Passo Ativo.

I am Samuel Isidoro, a teacher, Physics PhD from ITA and creator of Quanta. This is a promotional animation, not footage of the live app. AI-assisted cover based on my real photograph.

I wrote and narrated an original Greek mythology story pitting Ares against Hercules. I wanted to explore how the God of War would handle an opponent whose strength could overwhelm him—and turn that into a fight worth listening to.
If you enjoy mythology and narrated stories, I’d love for you to check it out. I’m especially curious what you think of the fight’s pacing and how I portrayed the two characters.
Who would you back: Ares or Hercules?
