How Does Prime Spirals - Numberphile Work?

Imagine you're drawing numbers on a spiral like a snail shell, that’s how Prime Spirals from Numberphile work!

You start in the middle and move out, writing numbers as you go: 1 is in the center, then 2, 3, 4, and so on. The pattern looks like a spiral, kind of like when you wind up your toy phone or a ribbon around a gift box.

Now, prime numbers are special, they’re only divisible by 1 and themselves. Like 2, 3, 5, 7, 11… the list goes on!

When you color in all those prime numbers on your spiral, something surprising happens: they line up in diagonal lines, like little highways for primes. It’s like if every time you took a step forward, you dropped a red bean, and suddenly, you saw patterns everywhere!

This is super cool because it shows how math can hide neat tricks inside simple spirals, just like how your favorite toy might have a secret way to wind up! Imagine you're drawing numbers on a spiral like a snail shell, that’s how Prime Spirals from Numberphile work!
