STEM Lores

Math · Physics · Chemistry — animated history of science

Every number,
every law,
every element
has a story.

STEM Lores tells them: the people, the mistakes and the moment it finally made sense — then the idea itself, animated. Three YouTube channels, one curiosity, and the written story behind every video.

The channels

Each one with its own narrator, music and look.

The stories inside the elements.

The Element Files: who found each element, what it does to us, where it hides in your life and the strangest thing it ever did — from hydrogen to the end of the periodic table.

First story premieres soon

More than forty years on, it is measured to twelve digits and still unexplained.Physics Lore · 6 min readWhy Does 137 Haunt Physics? The Strange Story of the Fine-Structure ConstantA pure number with no units sets how strongly light grips matter.

How the Lores are made

01

Real history, checked

Every story starts from sources — papers, letters, lab notebooks. Numbers and dates are checked by a person before anything is published.

02

Animated with code

Diagrams, simulations and proofs are drawn programmatically, so a wave moves by its real equation and a proof builds one step at a time.

03

Honest about the voice

Narration is synthetic text-to-speech, and every description says so. Each channel has its own narrator, music and visual language.
