  • Dear Nickelodeon, I've gotten over how SpongeBob's pants are

  • not actually square.

  • I can ignore most of the time that Gary's shell is not

  • a logarithmic spiral.

  • But what I cannot forgive is that SpongeBob's pineapple

  • house is a mathematical impossibility.

  • There's three easy ways to find spirals on a pineapple.

  • There's the ones that wind up it going right,

  • the ones that spiral up to the left,

  • and the ones that go almost straight up-- keyword almost.

  • If you count the number of spirals going left

  • and the number of spirals going right,

  • they'll be adjacent Fibonacci numbers-- 3 and 5,

  • or 5 and 8, 8 and 13, or 13 and 21.

  • You claim that SpongeBob Squarepants

  • lives in a pineapple under the sea, but does he really?

  • A true pineapple would have Fibonacci spiral,

  • so let's take a look.

  • Because these images of his house

  • don't let us pick it up and turn it around

  • to count the number of spirals going around it,

  • it might be hard to figure out whether it's mathematically

  • a pineapple or not.

  • But there's a huge clue in the third spiral, the one going

  • upwards.

  • In this pineapple there's 8 to the right, 13 to the left.

  • You can add those numbers together

  • to get how many spirals are in the set spiraling

  • steeply upwards.

  • In this case, 21.

  • The three sets of spirals in any pineapple

  • are pretty much always adjacent Fibonacci numbers.

  • The rare mutant cases might show Lucas numbers or something,

  • but it will always be three adjacent numbers in a series.

  • What you'll never have is the same number

  • of spirals both ways.

  • Pineapples, unlike people, don't have bilateral symmetry.

  • You'll never have that third spiral

  • be not a spiral, but just a straight line going up

  • a pineapple.

  • Yet, when we look at SpongeBob's supposed pineapple

  • under the sea, it clearly has lines

  • of pineapple things going straight up.

  • It clearly has bilateral symmetry.

  • It clearly is not actually a pineapple at all,

  • because no pineapple could possibly grow that way.

  • Nickelodeon, you need to take a long, hard look in the mirror

  • and think about the way you're misrepresenting

  • the universe to your viewers.

  • This kind of mathematical oversight

  • is simply irresponsible.

  • Sincerely, Vi Hart.
