ApliantMath you can see, hear and touch.
Each lab starts from something of yours: a picture, a drawing, a guess. Then the math runs in front of you. Change a number and watch what happens. Everything runs in your browser, and every lab can be saved as one HTML file that works offline.

Fourier Draw
Draw any outline with spinning circles. Upload a picture, choose how many circles, listen to your shape.
- Fourier series
- complex numbers
- sound
- compression
Curve Workshop
Bézier curves and splines, the curves behind every font and vector drawing. Drag the points and watch De Casteljau build them.
- Bézier
- splines
- interpolation
- geometry
Chance Machine
Drop thousands of balls and watch the bell curve appear. Sum any dice you like: the result always ends up normal.
- probability
- central limit theorem
- Monte Carlo
- statistics
Chladni Patterns
Make a plate sing. Sand runs away from what moves and draws the hidden shapes of each note.
- vibrations
- waves
- resonance
- eigenmodes
Sorting Sounds
Watch and hear how computers put things in order. Race the algorithms and count every comparison.
- algorithms
- complexity
- sound
- computer science
Eigenvectors
A matrix bends the whole plane, but some arrows only stretch. Find them, and see why they rule Google, populations and photos.
- linear algebra
- matrices
- eigenvalues
- PCA
