Professor Cracks the Christmas Code With Maths Magic!
Oliver Johnson, a top Information Theory professor at the University of Bristol, famed for demystifying pandemic stats, is back. This time, he’s diving headfirst into festive frenzy with his debut book Numbercrunch, hitting shelves next year from Heligo Books. It turns out, Christmas chaos isn’t just tradition – it’s full of numbers, from baubles to Santa’s world-beating logistics.
Deck the Tree – But Don’t Go Random!
Think throwing baubles on the tree is easy? Think again. Professor Johnson reveals a festive faux pas: random decoration creates odd gaps and eye-sore clumps.
“If you hang 100 baubles on 100 branches randomly, over a third of branches end up bare, and some get four baubles,” Johnson warns. “A ‘quasi-random’ approach – somewhere between strict pattern and chaos – looks best.”
Wrap Smarter, Save Paper
Forget the festive struggle with wrapping paper. Maths legend Isaac Newton—and Maclaurin’s inequality—come to your rescue.
Johnson explains, “If you want to save paper, pick gifts close to cube shape — sorry, no sugar cubes! Chocolate Oranges wrap easier than flat bars too, so keep Santa’s reindeer happy with those.”
The Hidden Maths of “The 12 Days of Christmas”
Think you know the classic carol? Think deeper. Pascal’s Triangle hides inside the song, revealing a festive number puzzle.
“The number of presents each day matches the triangle’s diagonal numbers — 1, 3, 6, 10, and so on,” Johnson explains. “By Day 12, you’ll have 364 presents in total, with geese-a-laying and swans-a-swimming dominating.”
Santa’s Ultimate Route Puzzle – A Logistical Nightmare
Visiting every home globally in one night isn’t just magic; it’s the brain-busting Travelling Salesman Problem. Scientists took 136 years of compute time to crack 85,900 stops.
Johnson suggests, “Santa might have secret weapons like a quantum computer to beat these odds. It’s the only way to calculate his super-speed route efficiently.”
Chocolate Box Chaos: Beware the Last Piece
We all dread being stuck with the dreaded last chocolate. Maths can predict your misery.
“If your box has 24 nice and 6 nasty chocolates, the chance the last chocolate is nasty is 20%. But if people return bad chocolates back to the box half the time, that chance jumps to 64% – yikes!”
Stack Your Baubles Like a Genius
Fragile baubles take precious space, but centuries of maths have a solution: the hexagonal layered pattern.
“For centuries, the best pack is a hexagonal layered pattern. This was only proven by computer in 1998. And top mathematician Maryna Viazovska even won a Fields Medal for packing spheres in 8 and 24 dimensions!”
Not your average Christmas trivia – but a cracking fact for your festive quiz!
