To settle on an answer, we need a sufficiently precise definition for both “door” and “wheel”.
I’m going to argue from the definition that a door as a manmade object intended to allow the passage of a person from inside an enclosed region to outside of an enclosed region, or vice versa.
Similarly, I’m going with a wheel being a manmade object intended to support the weight of an object attached to, or resting upon it, and designed to smoothly rotate to allow the attached object to move.
Because I have allowed for very small wheels, while requiring doors to be pretty large, I suspect wheels are more numerous. Ball bearings are probably the most common wheel, and there are at least 2,000 of them in my house, plausibly enough to outnumber the doors on my house, my car, and every house and car in my neighborhood.
Easily wheels. Every roller bearing in things like drawer slides, sliding closet doors, sliding shower doors, sliding screen or glass doors, etc. are technically a kind of wheel. A single door could have multiple wheels. Garage door segments with multiple wheels as rollers pre segment. Cars, bicycles, scooters, skateboards, motorbikes all have multiple wheels. Wheels aren’t just for locomotion. 18 wheel trucks have only two doors but obviously 18 wheels, not including any hand-trolleys it might have in the back for loading/unloading. Trains have multiple bogies usually with 4 wheels each and two to a car, 8 wheels per car and maybe two to four doors.
But wait, what about an office building full of hundreds of doors? Think of every office chair with multiple wheels. Desk drawers. Office carts. Elevator pulleys, doors, and guides.
Wheels win.
Way more wheels than doors.
All creatures have an anus, and an anus is technically a door. Think how many insects there must be.
This has broken my brain.
I have 40+ wheels I can think of in my house. Chairs, carts, bikes, shit there’s even one on my mouse. That’s not even counting all the wheels in my massive Lego collection.
But then again… Cabinet doors, microwave, refrigerator, oven… Fuck!
What have you done to me?
Depends on how you count wheels.
A bicycle has two wheels right?
Well, what about the bearings? Those are basically little wheels, should we count those? Now hold up a sec, inside the bearing, there are either balls, or rollers, which actual like little wheels for the bearing to turn on… so maybe a bike has like… Over 40 wheels on it.
Personally, I think I’m going to go with wheels over doors. I can think of a lot of doors that have wheels in them, but I can’t think of that many wheels that have doors in them.
How many doors does a revolving door count for, one for each partition in the device or as a single door?
Does a wheel count as the circle or the assembly? Does a two wheel caster on a chair count as 2 wheels or one? Would a desk chair with 5 casters count as 5 wheels or 10?
Easily doors. Every house has a ton, every building has a ton. Cars are mostly even on the door to wheel ratio leaning towards more wheels but not enough to offset.
Lawnmowers, wheel barrows, trash bins, grocery carts, bicycles, roller skates/blades, scooters, trains, semi trucks, dollys, forklifts, and that’s before mentioning things like flywheels, pulleys, steering wheels, etc.
Gears are wheels.
Damnit, you’re right, how the hell did I forget that one?
Crazy to think some watches have more wheels than houses have doors
Fake doors? Real doors? Real fake doors?
Fake wheels? Real wheels? Real fake wheels?
Real talk here: is there a class of mathematical problem where trivial set sizes lead to provable (and sometimes intuitive) conclusions, but real world data sets become uncountably large, thereby being unsolvable? I want to say all this resembles NP-hard in that way (e.g. picking small teams for basketball is easy, huge is not), but we’re not doing any real math here.
At the same time, No True Scotsman is in play since how the fuck do you agree on a definition of “a wheel” or “a door?” Hell, technically speaking: both have axles and can rotate!
Depending on what counts as a wheel, I counted our vehicles, bikes, trailer and came up with 22. Then counted doors - things that are on hinges with handles to open/close that divide one room from another but not cupboard doors and came up with 26. If I add cupboard doors would be a bunch more. But then I could probably find more wheels - wheelbarrow, other machines?
Wheels, just because of Lego
Today, almost 50% of all Lego sets contain wheels.
And this is without getting into non-vehicle wheels like flywheels, gearwheels, etc
Depends how generous we are with the definition of door. Do we consider any sort of opening a door? Is the way bugs get into the ground a door? If so, then doors. Otherwise it’s probably wheels. I think the general definition for what we consider a wheel (without getting really loosey goosey like I was before) is much more broad. A door is something for a person to open and close. A wheel is a round thing that spins. Even if you’re thinking something like “well, buildings have a lot of doors, and there are more buildings than cars…” Consider that a lot of furniture has wheels. Drawers have wheels. My dishwasher has a “door” but the racks have wheels. My office chair has 5, maybe 10 depending on how you count. I’ve got like four in the house I think. That’s already like 40 wheels from just office chairs.
Same goes for the definition wheels, though. Do Flywheels count? Water wheels? Is any round object meant to rotate on a fulcrum fair game? Are tires disqualified?
Like, think about how many toy car wheels there are.
My point is that the natural, not trying to push the limits definition of wheel is already much broader than door.
I thought the wheels had it easily, but then I started counting cabinet doors and I’m not so sure anymore.
Imagine a big hotel or apartment complex. I thought it would be wheels easily but I’m not so sure.
And most cars have four wheels and five doors, but then if you count the boot as a door then the bonnet is also basically a door to the engine.
How do you define wheel? That’s going to change the numbers. And how do we want to define door?
This is the semantic argument I’m here for.
If cogwheels are counted then I think there are more wheels
If transistors are doors then doors win.
Team wheel here. I’d expect the sheer number of wheels inside mechanisms and machines to clinch it.
Doors. The ones in Hilbert’s hotel alone outnumber the wheels.
This question makes me feel like Jordan Peterson
