True stories

The roundabout of roundabouts

Swindon, England

In Swindon, England, sits a junction so strange that visitors slow to a crawl just to stare at it. Built in 1972 by traffic engineer Frank Blackmore, the Magic Roundabout is not one circle but six: five small roundabouts arranged around a central ring. Cars on the outer loop travel clockwise, while traffic on the inner ring flows the opposite way, giving drivers a surprising number of routes through. It looks like chaos, yet it moves heavy traffic smoothly and has a strong safety record, because everyone slows down and pays attention. Locals navigate it without a second thought, proof that a clever arrangement of simple circles can outperform a single grand design.

A puzzle bees solved first

Ann Arbor, Michigan

For nearly two thousand years, people wondered why honeybees build their combs from hexagons rather than squares or triangles. The Greek thinker Pappus guessed the answer around 300 AD: hexagons store the most honey using the least wax. Proving it mathematically was far harder. The question, known as the honeycomb conjecture, resisted every attempt until 1999, when mathematician Thomas Hales at the University of Michigan in Ann Arbor finally cracked it. His proof confirmed that no tiling of equal cells beats the hexagon for efficiency. Bees had been quietly using the best possible shape long before anyone could explain why it works.

Did you know?

triangle: The triangle is the sturdiest shape, which is why bridges, roof trusses, and bike frames are packed with them for strength.
circle: A circle has no corners and one unbroken edge, with every point sitting the same distance from the center.
diamond: A diamond is just a square balanced on one corner, and baseball borrowed the name for its four-base infield.
hexagon: Bees build hexagon cells because that shape stores the most honey using the least wax, a fact mathematicians proved only in 1999.
pyramid: Egypt's Great Pyramid stayed the tallest building on Earth for about 3,800 years, longer than any structure before or since.
crescent: A crescent is not the moon's true shape but our view of it, the lit sliver where sunlight catches one curved edge.
octagon: A stop sign is an octagon, and its eight distinct sides let drivers recognize it even from behind or in the dark.
pentagon: The Pentagon near Washington is the world's largest office building, named simply for its unmistakable five-sided shape.
cylinder: Soup cans, batteries, and paper-towel rolls are all cylinders, a round shape that both stacks neatly and rolls easily.
rectangle: Most doors, books, and phone screens are rectangles because right angles make them easy to build, stack, and fit together.
square: A square is the only rectangle whose four sides are all equal, the reason graph paper and city blocks use it.
sphere: A sphere holds the most space inside the least surface, which is why bubbles, raindrops, and planets all pull themselves round.
spiral: Spirals appear in snail shells, sunflowers, and whole galaxies, often following the same growth pattern mathematicians call the golden spiral.
ellipse: Planets orbit the sun in ellipses, gently stretched circles that Johannes Kepler first described over four hundred years ago.
rhombus: A rhombus is a slanted square with four equal sides; a baseball diamond is really one tipped onto its corner.

Trivia

Why are most manhole covers round rather than square or rectangular?
A circle has constant width, so a round cover cannot fall through its own hole.
How many sides does a stop sign have in the United States and many other countries?
Eight; it is an octagon.
What shape are the cells in a beehive's honeycomb?
Hexagons (six-sided).
The British 50 pence coin has an unusual shape with how many sides?
Seven; it is a constant-width heptagon.
In geometry, what do you call a solid ball-shaped figure that is perfectly round in every direction?
A sphere.

In their words

When I am working on a problem I never think about beauty. But when I have finished, if the solution is not beautiful, I know it is wrong.
Buckminster Fuller

Bees, by virtue of a certain geometrical forethought, knew that the hexagon is greater than the square and the triangle, and will hold more honey.
Pappus of Alexandria
