Math.Visualised

@math.visualised  ·  animations made in Manim

Every formula is hiding a picture.

I animate mathematics so you can watch why it works, not just memorise what to write down. Short, precise, and made for the screen in your hand.

Animations

Recent pieces that travelled furthest on the feed. Each frame below is a placeholder, sketched in the style of the finished render, until the video itself lands here.

  1. Video placeholder · 01 Complex Series Σ zn/2n|z| < 2 z/2 Video coming soon

    01

    Complex Series

    The partial sums of Σ zⁿ/2ⁿ spiral home to 2/(2−z), then the camera dives into the self-similar centre.

    Complex analysis

  2. Video placeholder · 02 Gram–Schmidt u1 u2 v2 u1 · u2 = 0 Turn any basis into an orthogonal one Video coming soon

    02

    Gram–Schmidt

    A projection is a literal shadow. Subtract it, tilt into 3D, subtract twice, and three vectors stand perpendicular.

    Linear algebra

  3. Video placeholder · 03 Heron's Formula 15 14 13 Area = 84 No height needed Video coming soon

    03

    Heron's Formula

    Three side lengths, one semi-perimeter, and the area of a 13–14–15 triangle, without ever drawing its height.

    Geometry

  4. Video placeholder · 04 Systems of Equations R1 ← R1 − R2 − R3 1002 0101 0013 x = 2 y = 1 z = 3 Video coming soon

    04

    Systems of Equations

    Isolating everything gets messy fast. Row-reduce one steady matrix instead, and the answers slide out.

    Algebra

More slots open as new animations are rendered. Follow along to see them first.

Playground

Twelve graphs you can grab. Open one, drag the points, slide the numbers, and watch the mathematics answer back.

    About

    @Math.Visualised
    Fig. 3 The last frame of every video.
    A proof you can watch is a proof you remember.

    I'm the person behind @math.visualised. I make short animations with Manim, the Python library created for 3Blue1Brown, and share them with the 11,000+ people who follow along.

    What pulls me in is the moment a formula stops being a row of symbols and becomes something you can see: a projection that is literally a shadow, a triangle whose area appears without ever drawing its height, a series that spirals home to its limit.

    This site is where those animations live, next to a playground where you can change the numbers yourself and watch the mathematics respond.
