Pineapple under the sea.... Really?
January 29, 2012 2:59 PM   Subscribe

So, Nickelodeon, you tell us that Spongebob Squarepants lives in a pineapple upside down house at the bottom of the sea. Are you really sure about that? Beware of misleading your viewers about the universe, Nickelodeon!

Spongebob's house (room by room guide). Pineapple Fibonacci spirals. A (mathematically correct) pineapple house that you can stay in. Slicing your pineapple Fibonacci style. More Vi Hart. Vi Hart Previously and again..

Pineapple under the sea? Really?

It's a show where a living sponge (not the animal type, but the kitchen type) is friends with a talking starfish and works at a fast food restaurant where the sponge grills patties. The sponge's love interest is a squirrel, that lives in a glass bubble, and the squirrel manages to bring in fresh air as to not suffocate.

Also, David Hasselhoff operates as a motorboat.

And you, sir, complain about the math of a crude drawing.

Next you'll be telling me that Tasmanian Devils don't actually travel by spinning around like a tornado, and that roadrunners aren't really several feet tall with purple plumage and making meep meep noises.

I also love how the featured video never ONCE uses an actual illustration of the pineapple from the series (which seem to vary widely anyway). So how can we know any of what is contained there as a critique is accurate?

"This is a show that has fire underwater."

That is, in fact, much more plausible than Spongebob's house that is totally not a pineapple. All you need for combustion underwater is an alternate electron acceptor.

I'd take it lighter if i didn't know people that do this kind of thing in all seriousness. They do it with things that aren't even trying to be scientifically plausible (Spongebob with fire underwater for one), like that CG Resident Evil movie and not shutting up for close to half an hour about how something can't increase in mass, or how in Tron people "don't live in computers".

Swap out cute nerd for annoying borderline aspergers guy and this starts to lose its cuteness pretty quickly.

The snail was cute though.

I figure that's because putting any actual footage of Spongebob on Youtube tends to bring Viacom down on you like the fist of an angry god.

This reminded me that I wanted to browse the rest of her videos. So far, this one is my favourite, followed closely by snakes and more snakes.

I think our problem is that the Pineapple appears to be bigger on the inside than the outside AND WE REFUSE TO BELIEVE IT'S A TARDIS.

I adore Vi Hart. Even students who don't get the math she's explaining actually try to understand it when they watch her videos, which is more than many of them do in a classroom.

Everyone needs to snarf down some of that cool button candy she made a video with and watch the one where she makes a mobius-strip player-piano roll.

Or the camel fractals....

Vi Hart is great and I'm going insane - because I could swear that I heard her lisp in this video, which she's obviously never done before.

Thirty-plus comments, and nobody has pointed out that a cored-pineapple structure would not survive the water pressure at the bottom of the sea, for most values of "the bottom of the sea"?

Sandy Cheeks is not Spongebob's love interest. Like Patrick, she is his friend. That's it. Spongebob has no love interest. He has like a nine year old boy's brain.

Of course it would. It doesn't need to be filled with anything other than water, because SpongeBob is a sponge. Don't be absurd.

Aside for the mathematically impossible pineapple, there really isn't anything on that show that can't be explained

Heh, I love the "she is so not describing Spongebob!" responses.

I enjoyed Vi Hart so much the last time she showed up on Metafilter that I watched all her videos, then sent the links off to a colleague in the Math department. She passed them on, and a number for her colleagues were unamused... because Vi Hart suggested that Math class could be boring.

I was making the same face then as I am now.
posted by GenjiandProust at 6:08 PM on January 29, 2012


Best dirty joke in Spongebob: the town he lives in is called "Bikini Bottom." Think about it.
posted by ColdChef at 6:16 PM on January 29, 2012


Y'know, I love Vi Hart, but I feel like she's coming at this pineapple thing backwards. It's not that Mathematics has somehow decreed that all pineapples shall have Fibonacci spirals, but that pineapples tend to grow in this cool spiral pattern. The pattern doesn't come from Math - it's just the most efficient way for the little pineappley growth pods to spread themselves out.

What's remarkable is that this crazy sequence that Fibonacci wrote down just to happens to mirror what actually occurs in nature - it's a testament to the power of math to model the world (rather than the world being somehow predestined by mathematics.)

BTW, the process of this growth is called Phyllotaxis. Pinecones exhibit similar cross-wise spirals (left and right, not l/r/vertical like pineapples.) If you get a (full) stalk of broccoli and cut it just right, you can see that each successive branch is around 137.5 degrees off of the previous one. 137.5 degrees being the "golden angle" which is derived from the golden ratino which can be approximated by... the Fibonacci sequence. Cool huh?

For more info, see The Mathematics of Life which explains this more elegantly than I do.

posted by benito.strauss at 7:09 PM on January 29, 2012


What happens with plant growth (you see this in sunflowers too) is that the angle between pods pretty much HAS to be 137.5 degrees. Even a small deviation in the angle of new shoot growth tends to create very visible spiral structures, which are definitely not an efficient way to grow!

I made an animation of what happens when you change the angle slightly. Watch how at 135 degrees, the formation has distinct "arms", which disappear as the angle approaches the golden angle, then begin to reappear as the angle approaches 140. Nature is cool! Math is cool!

Yes, and I believe this Spongebob character wears square pants. Show me the maths Nickelodeon - if you dare!
posted by mattoxic at 7:14 PM on January 29, 2012


His pants are clearly rectangular. Unless by "square" one means having squared-off corners, which has more to do with 90 degree angles than any actual definition of "square" as a geometric shape.
posted by hippybear at 7:17 PM on January 29, 2012


I've found that, at least in the days where I cared how my ass looked, the squarer my pants were, the better/less square my ass looked. There's probably a mathematical way to explain this, but some things are better left unexplained.

Guys guys, you are getting worked up over nothing. This is clearly a satirical take on nerd culture. As a group, we accept all the impossible things about the star wars universe and then get ben out of shape over explosions in space.

There is shockingly deep mathematics around knot and braid theory, witness the Jones polynomial which von Jones discovered by exploring Subfactors of von Neumann algebras.

It snows in Bikini Bottom too. And things catch on fire. And Spongebob got stuck at the bottom of a wishing well when he could have just swam or even floated up to the top (not to mention Patrick and Squidward falling down the well, which wouldn't have happened that way either). You could probably fill an encyclopedia with ways in which the show doesn't seem 'realistic' as regards the physics of being underwater.

It probably helps just to forget it altogether really.

Holy Zarquon's Singing Fish writes "My favorite bit of Spongebob physics is that the Krusty Krab has a walk-in freezer."

My favourite headbanger is that most inhabitants drive boats with wheels instead of cars or submarines. Of course the submarines don't appear to have any airlocks so they are more like enclosed boats anyways.
