Beautiful mathematics you can pick up and play with, arranged in six rooms. Each exhibit has a “What’s the maths?” panel that names the branch of mathematics, shows where it sits on the Sec 1–4 syllabus, and explains what you are looking at.
Results that feel wrong until you run them — and then feel wrong for being right.
Pick a door, the host opens a goat, then: stay or switch? Play it, then simulate ten thousand games and watch the answer that fooled mathematicians.
Enter exhibit →How many people before two share a birthday? Fill a classroom one seat at a time and see the answer land at 23, not 183.
Enter exhibit →Drop needles on floorboards, count the ones that cross a crack, and π falls out of the ratio.
Enter exhibit →Take the first digit of real-world numbers — populations, river lengths — and 1 shows up six times as often as 9. Fraud investigators use it.
Enter exhibit →Treatment A beats B in every group of patients, yet B wins overall. Drag the numbers and watch the reversal appear.
Enter exhibit →Geometry that breaks your intuition about what a shape can and cannot do.
The only shape with exactly one stable and one unstable balance point. Knock it over and it always rights itself, with no hidden weight.
Enter exhibit →A surface with one side and one edge. Cut it down the middle and you get one long loop, not two.
Enter exhibit →A wheel that is not a circle yet rolls a plank perfectly level — and drills a square hole.
Enter exhibit →Slice a cone and an ellipse appears. Two spheres tucked inside reveal its foci — the nicest proof in conic sections.
Enter exhibit →You cannot comb a hairy ball flat — one tuft always sticks up. That is why there is always a windless spot on Earth.
Enter exhibit →Count the dots inside and on the edge of a lattice polygon and its area drops out: I + B/2 − 1.
Enter exhibit →Stack oranges the grocer’s way and nothing beats 74 %. It took 400 years to prove.
Enter exhibit →Simple rules, run again and again, that build order — or chaos — no one wrote in.
Move five discs in the fewest moves. Watch the recursion unfold, see the binary counter hiding inside, and learn why 64 discs outlast the universe.
Enter exhibit →Two identical pendulums released a hair apart go their separate ways within seconds. Fully determined, yet unpredictable.
Enter exhibit →Balls bounce left or right down a board of pins and the bell curve builds itself. Pascal’s triangle is hiding in the pins.
Enter exhibit →One line of algebra, z → z² + c, repeated forever. Zoom in and the structure never runs out.
Enter exhibit →Four rules on a grid, and gliders, guns and self-copying patterns emerge. Order from almost nothing.
Enter exhibit →Grow a sunflower head one seed at a time. Only the golden angle packs them without gaps — and Fibonacci spirals appear.
Enter exhibit →Sand on a vibrating plate draws nodal lines. Change the frequency and the pattern snaps to a new figure.
Enter exhibit →What shapes look like when you change the space they live in.
A cube’s shadow is a square, so a 4-D cube’s shadow is a cube. Rotate one through the fourth dimension and unfold its eight cubes into a net.
Enter exhibit →Only five perfectly regular solids exist. Build a vertex, watch the angles run out, and see why a sixth cannot close up.
Enter exhibit →A world where triangles have angle sums under 180° and infinitely many parallels pass through a point. Escher drew it.
Enter exhibit →Project the Earth onto a flat map and Greenland balloons. Every flat map lies — here is how much, and where.
Enter exhibit →Stack spinning circles tip to tail and they trace any drawing you make. Waves are rotations in disguise.
Enter exhibit →Dots, lines and rules — and the surprising things you can prove about them.
Try to walk every bridge exactly once. You can’t, and Euler’s 1736 argument about odd and even corners tells you why, and how to fix the city.
Enter exhibit →Colour any map so neighbours differ. Four colours always suffice — try to design a map that needs five and fail.
Enter exhibit →Visit every square of the chessboard exactly once with a knight. Its cousin, the Euler path, is easy; this one is genuinely hard.
Enter exhibit →Drop schools on a map and see which one each home is nearest to. Every boundary is a perpendicular bisector.
Enter exhibit →Connect three houses to three utilities without crossing pipes. Impossible on a plane, easy on a doughnut.
Enter exhibit →Theorems that become obvious once the pieces move.
Water from the two small squares pours into the big one and fills it exactly. Then three dissection proofs, animated.
Enter exhibit →Odd numbers stack into a square. Two staircases slide into a rectangle. Cubes rearrange into a square of a triangle.
Enter exhibit →Slice a hemisphere and a cylinder-minus-cone at the same height: equal rings every time. That is where ⁴⁄₃πr³ comes from.
Enter exhibit →
