I think everyone's answer will depend heavily on how they define doors and wheels. If I had to put money down on man-made objects only, I think I'd still go with wheels. There are lots of mechanical and industrial objects that incorporate thousands of wheels and ball-bearings into their design. Even just a 30 foot conveyor belt could contain hundreds and hundreds of wheels. Wheels are a design that can be miniaturized and repeated over and over again and still be useful, while the intended purpose of doors puts a lower limit on their size and repeatability.
and what about transistors? those count as doors
Good reasoning
@@IskanderVFX A door has to have a hinge.
@@IskanderVFX they dont physically open and close though, they just toggle between conducting and not conducting
That was the first thing that came to my mind. A single industrial town has more wheels than there are doors in the entire USA. All them bearings...
Dog estimation: The step you skipped was accounting for people owning multiple dogs. I ballparked that as 2/3 of the people who own dogs own an average of two dogs. I was kinda shocked at how close I got with that.
Wait a sec those little creatures need food right and they have mouths right? could mouth be considered a door?
and stray dogs, i estimated that there were like 5 millions stray dogs and guessed 70M
@@lindahamilton2996Mouths and arseholes - both doors.
No that's a hinge, limited rotation @@lindahamilton2996
I was nowhere near the true number. My estimation was 13 millions. Fuck Fermi.
Do revolving doors count as both? because they're basically large paddle wheels?
Asking the REAL questions here
Sliding doors also have at minimum 4 wheels each
You didn't watch the video yet didn't you
Thank you for bringing up what programmers have to deal with all the time. The wonderful world of EDGE CASES!!!
@@raygonzales2208 Eeeh most sliding doors I know of use Ball Bearings, not wheels.
The flagella is really fascinating, it's literally like a tiny electro motor.
Also: Could you consider a semiconductor as kind of a door? Still wouldn't beat it, but sure would increase the number of doors :)
It's literally a mini eletric motor!
Also, if we consider semiconductors doors, then bacteria's channels can be considered doors as well, beating wheels by a large margin
Bacteria channels, is a HUGE STRETCH. To me at least. The flagella is quite literally a motor with a wheel we can see that, but a bacteria channel? Naw
If flagella count as wheels when they are basically just a tail (not a wheel) on a rotating axle, then we should could anything in nature that functions like a hinge in the door category. Elbows for example.
@@elijahbachrach6579 well thats a hinge, not a door. A flagella has a rotating thing, its literally a wheel
You know the episode is gonna be a banger when Kyle breaks out
the Fermi estimates
I was all in on doors, until I stopped and thought about just my apartment. I counted 24 doors, including cabinets, electronics, appliances, even the dish detergent tab, and the like. Then I realized I’ve got ~8 sliding drawers and a sliding door with presumably >4 castors apiece, not to mention all the motors in said electronics.
Then I remembered I work in a performance hall, and the wheels in our 60+ rail fly system probably equals the number of doors in the building on its own.
I was a door guy too until I started thinking about my office. Dozens of doors in the building, hundreds when you count in-office kitchens and what not, but every office chair has 8 wheels on average, and there are easily as many chairs as doors. Wheels go bonkers in this bitch.
What really sold wheels for me was wheely office chairs. Each one has about 12 wheels on the castors.
@@doseven you know what sold me? The fact that there is sometimes more wheels than doors like on an 18 wheeler, but there is never less wheels than doors on a car. Plus the amount of trains
I don't know. I think this is taking things to an extreme vs the original question's intent. For this purpose I would define a DOOR as a door a human being could plausibly walk through and it opens and closes. And a wheel as a wheel for the intention of locomotion of an object on a road or road like device. I mean you say yourself - castors and motors. Yes, it's a wheel in the abstract sense but it's not what I think the original question intended. Honestly, this video was the first really disappointing video from him.
You really need to put sane limits on this. I would even go as far as saying that toy doors and toy wheels wouldn't really count here. If it's not supporting a human being or could support a human being, that's normally not what I think. Maybe a few exceptions like a dolly wheel or wheel barrow's wheels. But a hot wheels door or hot wheels wheel seems like it should be filed under 'de minimis' - it's so small and trivial, it doesn't really count.
Now, let's lay down some realistic definitions here.
A door ... It can open, close, and support at least a human toddler walking through either direction, and is a solid material or mostly solid material (no tent flaps, no fence gates). It most likely needs a door knob or equivalent mechanism (so we can include elevator doors too, it's pretty much the same).
A wheel ... It is wood, rubber or similar material intended for moving a larger object across a road, track, or passage. Metal would be acceptable for trains. In my opinion I would say it needs to move something significant, ... More than a toy. However if you really want to include hot wheels or Lego, fine ... As it's kind of arbitrary to exclude them but my human mind just says it seems right to exclude a wheel thats so tiny. Again we could use the definition that it should be able to support a human toddler's weight if balanced correctly.
If we're including castors and flagellum and the like it seems like we're really asking "are there more circular objects that spin or more square objects that open and close" ... Different question.
@@MrAB-fo7zk "This is taking things to an extreme" proceeds to write the bible.
Ive always thought this question was easy to answer, since mechanically there are many more tiny wheels than doors. But I guess it would have to depend on how you would define a wheel and a door. Gears can be wheels too, and I think its easy to say that there are more gears in the world than doors. In fact, certain dictionaries can even view circular door knobs as wheels.
Yeah exactly, much more wheels. I can't think of any way that there are more doors
Yes, sitting here at my dest alone I could easily count at least 30 wheels. Including the wheels slides in my metal desk, 6 drawers makes at least 12 wheels. My monitor arm has ~5 joints each of which have a wheel. And my 3d printer has at least 10 bearings, or wheels, and 4 printed gears I use as handles to level the bed. Also I have a generous estimate of 5 doors including closet door, room door, a chest lid, and a couple of computers that have a hinge openings.
Is a transistor like a door for electrons?
@@Klipik12 I was thinking about transistors as well
A lot of doors arguably (and some less arguably) have wheels on them - as noted, doorknobs, but also locking mechanisms often have multiple gears which might count, and some large doors as well as many sliding doors of various sizes also have wheels to aid them in movement. So many doors are not just a door but multiple wheels, tipping the scales further in favour of wheels depending on the definition you use (the one provided in the video includes gears and circular doorknobs as valid examples of wheels).
Curious question: would ion channels count as doors? Allowing electrolytes (sodium, potassium, etc) to flow between membranes fits the definition of a door in this case
Personally I think contrary to the video, both should only be defined as human designed or constructed objects otherwise you get a whole mess of nature doors
If a protein spinning count as wheels I think ion channels should count as doors. And there are definitely more ion channels than flagella
He addresses this in the bit at the end with the patreon names going by
@@BuildersOfBlocks yeah but still there are many different types of channels, some of them can close and open like a door
are transistors considered doors?
Lol he's been thinking about this nonstop for weeks since the last time he talked about it
Good... i would hope to expect a thought through answer from a channel like this.
Or have you expected some random numbers by dice?
Me too
Y'all broke Kyle!!!
The betterhelp sponsorship makes sense here.
When I started thinking about this problem, first thing I saw was just how loose of a definition there is for door or wheel, So, to keep from going down the rabbit hole of trying to decide if a gear inside a watch would count as a wheel, I had decided to try and refine the definitions for door and wheel to make them more clear.
Kyle's approach was interesting: loosen up the definition until you find a clear answer :P
To me, the spirit of the question would limit doors more than closable portals, rather they should be defined as a practical and intentional throughway for _travel._ This would preclude things like cupboards and windows.
With that definition I'm not sure you could come up with a similarly limited definition of what a wheel is that results in fewer wheels.
Indeed. If a wheel is a circular structure rotating about an axis, flagella are wheels. If a wheel needs to translate perpendicular to its axis, then flagella, conveyor belt rollers, and windmills aren’t wheels.
@@pXnTilde a door is a hinged divide to go from one location to another? I just cannot understand a definition of door which would somehow limit a door to not include a jaw. And there are sliding doors so art lips kind of like sliding doors as well?
A door is a hinged, rotating, or sliding barrier at the entrance to something, such as a house, vehicle, or cupboard. A wheel rotates on an axle and is intended to facilitate movement across the ground.
@@MaxG628 but would the millstone that is crushing the grain count as a wheel? xD
Fun video, though I would go about defining a wheel as a circular object rotating around an axis that bears weight and is used for rolling/moving a larger connected object along a surface (like the ground or rail). We wouldn't typically call a flagellum (or propeller) a wheel. I think the original question is hard though if we only stick to things that are typically identified "doors" and "wheels" by most people (like in a captcha).
Much better definition and quickly discounts the wierdos trying to claim hinges are wheels because there's a circle in it.... the circle is the axis sir.
A propeller can certainly be defined as a wheel?
Scientists in the 1950's: We just started scratching the surface. Imagine what we will learn in a few decades.
A few decades later: Are there more doors or wheels?
More grounded than "How many angels can dance on the head of a pin?" tho'
If you’re going to count flagella as a “wheel” then you need to include sphincters as doors.
Which means everyone with a butthole counts as a house.
Joke aside, sphincters and biological “doors” are pretty damn common and most organisms have more than one… humans have a handful of them!
And as he said at the start if membranes count it's wholly one sided
@@grognakthedestroyerattorne3211 we aren't talking membranes though, we are talking mouths and butts, and eyelids, and every sphincter. These have definitive openings and closings unlike the channels in cell membranes
@@mtnentertainment3454 Unless you can cite me a biological door more common to bacteria than flagella, your point is moot. Wheels still win based of the sheer weight of numbers of the microbial world.
counting the valves that control blood flow in your veins and most living organisms veins as doors should make the number jump up a lot right?
@@tsunamininja yep. Counting flagella as wheels definitely opened up another can of worms
By this logic, I believe the ATP synthase enzyme would count as a wheel. That would mean every cell has multiple wheels.
Yes, ATP synthase works in pretty much exactly the same way as the flagellum rotor. So most of the organisms on Earth have thousands of wheels in every cell.
But if we're calling membrane channels doors, then both flagella and ATP synthase are just revolving doors for protons!
nah
I also came here to comment about ATP synthase.
Correction: only cells that do aerobic respiration have ATP synthase
Thats what i was thinking too, thanks
Well, Kyle, as channels in the cell membrane can selectively let in certain materials and some are capable of mechanically opening and closing, I would say at least some percentage of cell membrane channels count as doors. And 100% of cells with flagella have multiple channels. So doors still wins!
Noted this before seeing the end credits bit, but I would say at least a percentage of the ion channels do indeed count. Especially because some of them are never fully open to the exterior, but rather (to anthropomorphize) grab the ion and then rotate it into the cell.
by oxford definitions doors win and its not close,
if you want to stretch definitions its easy to say that anything that spins is a wheel which would heavily favor wheels
Don’t forget transistors, which are doors for electricity.
i feel like this definition is more of a gate then a door
@@flerps3051 my friend is a gate not a type of door?
@@polarity2130 If we want to go sub atomic, every eletron is technically a wheel as they have an inherent "spin" no?
I feel like this is a conclusion based on a technicality. I think it'd be more fair to the spirit of the question to consider only man-made doors and windows. Otherwise, you could start to make an argument that cell membranes are doors or at least any sort of biological valve that opens and closes.
But wouldn’t ion channels in human cells technically be man-made?
Logic gates on a processor
@@janmelantu7490 I suppose that depends on if you're religious! This reminds me of an assignment I had to do early on in school to write out every step needed to make a PB&J sandwich and the teacher would specifically do it wrong when any small detail was not present...or trying to word a Wish spell in D&D.
Whether man made or natural things, wheels still win. Ion channels aren’t doors. They constrict closed or have ball and chain type mechanism. Unless you wanna consider a mouth a door or drain plug as a door, which they aren’t by any common definition, then wheels win.
@@ImBigFloppa I'm not sure this sways the victor at all but I would 100% consider a mouth a door. The jaw is by definition a biological hinge. It lines up the oxford definition of a door. No idea if I would consider Ion channels as that is a lot more subjective.
My pre-watch thought process: In general, nature makes more things than humans do. I know that nature makes chambers with entrances that can open and close. I know that nature almost never makes wheels, because growing a thing that rotates around an axle is very hard. So even if I can't get numbers, doors are far more common than wheels.
Edit: Dang it, good one.
It's in favour of wheels in terms of non-biological numbers anyway. The use cases or wheels is far greater than that of doors, and so there is always likely to be more wheels in circulation and production than doors. Toys. Hobbies. Emergency services and equipment. Transit. Even the amount of chairs with wheels is astounding.
Same, actually i still think doors wins, because of allí the doors or "Gates" that there are in la the membrane of cells in general, or those shouldnt be consideres doors? Also in a sense we might as well consider black holes as a one way gate 😂😂😂 not that there are many, but this examples are to show that if we consider a door a point between 2 somewhat separated regions and a wheel a point that spins in on itself It gets reaaaaaaaaaaaaaally hard top estimate, should we consider planets and stars wheels? Black holes that spins are both? (There has been some attempts to use a spherical wheel so we might as well take that into considerstion)
Even if only man made objects are considered, logic gates on processors are a thing. GHZ means billions. I would wager trillions of objects on earth have processors.
@@DarthObscurity they're not doors. =)
@@epmcgee
They can be doors for electrons
By this definition, hinges are wheels--circular and freely moving around an axis. Most doors use hinges, often more than one; if not, they use rollers. Thus, even neglecting biological wheels, there are necessarily more wheels than doors as doors require wheels. Thank you for coming to my TED talk.
I accept this as my answer now. Thank you
Hinges are not freely moving, they only have a certain range of motion.
hinges are not freely moving
Continuous vs non continuous rotation?
I don't believe hinges are wheels, and I don't believe toilet seats are doors. That's really stretching the truth.
I got 85,800,000 for the dogs. I figured out of 330 million people, 1/5 will have a dog, and the average dog owner will have 1.3 dogs. The 1.3 is pretty much a shot in the dark, but most have one, and a reasonable (but smaller amount) have two, and I just ignored any outliers more than two to get a little under 1.5.
With all the wheels involved in manufacturing, I am going to side with wheels being more numerous
While true, a lot of them would probably be ball bearings too, which shouldn't count as a wheel.
@@MindForgedManacle you think theres alot of doors in a skyscraper?
while true, alot of them would be counted as ceiling lights too, which shouldnt count as a door.
@@MindForgedManacle Does the ball bearing spin on its axis and is slim enough to be considered a wheel instead of a cylinder like a log? Yes. Gears are considered wheels too. Hinge is basically a wheel with limited motion. Due to hinge having an axle the door is made into a wheel by attaching an axle to it. Simple axle on a wheel. So every door is a wheel or has at least 1 wheel attached to it for movement
That's a particular variation of flagella that behave that way, not all flagella, and as others have said, many organic structures are equally analogous to doors. One that, while numerically possibly inconsequential, struck me as a good example was eyelids.
so you could’ve just said “i think eyelids are doors”
@@chickentikkamosalah I mean they do say the eyes are the windows to the soul, and many windows do have doors (not all windows but many)
flagella are way more common than eyelids, not to mention that calling eyelids doors is way more of a stretch
@@snoopzebra4234
Eyelids stop light to enter your eye (container). It's a door... i guess?
Also, there are more channels, and sphincters than flagella
Honestly, I love the thought regarding the "channels" that let stuff pass through membrane cells and if you would consider it a door. I mean you could get even more broad depending on classification, a wheel seems far more direct. For example, could you consider a gate a door? If so, would a arm thing used in car parks and toll booths be considered a "door".
Personally I would consider these channels that membranes use as a kind of door, however, their may be a better declaration, like they would be considered a door, but then isn't a valve a kind of door?
You can just go on and on for eternity 😄😄.
Maybe we need to have a global meeting to classify what is a door and go from their cause this is definitely a very important question that needs to be solved 😄.
Yeah thats really true.. It depends on how you define stuff.. But knowing that and reading a lot of definitions i come to the conclusion that wheels ultimately are the winner, if there only can be one universal winner.. Why? Because you have to bend definitions very very very hard to get more doors than wheels.. And even with just human made stuff counted as doors and wheels wheels will win by a factor greater than 2, maybe even way greater than 2.
I think this should only count artificial wheels and doors. Otherwise, you might as well start counting eyelids and the parts of cells that let molecules in and out as doors too
considering that there are more bacteria out there than stars in the universe, atoms in your body and grains of sand in the world, even if you counted eyelids and stuff, wheels would still win. Plus, osmosis is really not like opening and closing doors at all
@@Lambda_Ovine not technically
the parts of cells are more like filters
The electrons in atoms could be considered wheels as the also freely rotate, thus there would be infinitely more wheels!
@@SamuelHikida that's more of an orbit
When you consider that most hinges employ a rotating axis at their core, I am almost certain that wheels win without the use of bacteria.
Hinges and bearings don't count tho imo
a wheel needs to be able to spin freely about an axis, a hinge is stopped somewhere in the rotation
@@mtnentertainment3454 and thats the biggest problem. Cause to others they do count. I count gears and bearings as wheels since they operate on the same principle. I count all forms of doors, including elevators, drawers (which have rollers which are wheels), heck ill even count Windows as doors, and even the outside casing on computers. But all of that STILL seems to add to more wheels giving doors so many advantages, just because of gears and bearings if you count those, like me.
If wheels are circular frames that rotate around axles, then door hinges are wheels with plates attached to the sides
Doors CONTAIN wheels
If we’re going by human made stuff only, and using only the definitions you’ve given, wheels still win. For a long long long long long time, it was a lot easier to use hide or fabric or something to make a tent-style flap over a doorway, at the dime time that the wheel was around. I think it’s safe to say from a historical standpoint that at least there have been more wheels than doors.
again just think about all toy wheels around, sure some little toy doors are made, lego does them as they print wheels, but it's much rarer outside brik toys, they just don't compare.
Think about all the small castor wheels as well, used in dozens on the floor of cargo planes, or underneath a mechanics toolbox. There are usually 2 wheels per drawer in every (modernish) home. Also if we consider bearings a wheel then its just unfair for doors
@@thereservationatdorsia2618 you haven't seen a 6 tiered barbie doll houses toy skyscrapers not to mention every model houses architects make skyscraper replicas etc
For human made stuff, I think doors win hands down if you consider the gates of a transistor a door. Every computer, iPhone, etc has billions of gates doors inside it dwarfing anything else.
@@richardm123 gates of a transistor don't move.
But what about stuff in cell membranes, as mentioned at 0:11? Pumps and gated ion channels could be considered doors. At the very least, gated ion channels, which can open and close, probably fall under your definition of a door as a "hinged, sliding, or rotating opening to some room, vehicle, or container" (a cell would certainly be considered a container). Considering the number of cells in the world-including the wheel-equipped bacteria!-and how many of them have multiple pumps and/or ion channels in their cell membranes probably puts doors ahead of wheels instead.
Edit: Okay, I thought I'd stayed to the end of the video to make sure it wasn't mentioned before writing this comment, but apparently I didn't stay until after the end scene with the patrons. Sorry. I revoke my "insight". It would've been nice if membrane channels had been mentioned in the main content of the video, though, especially since it was a leading point in the intro.
Yep. This is the actual answer. Winner is Doors, always.
So if we're talking about non man-made doors what about non man made wheels? And what would constitute a wheel? Does merely has to roll to be a wheel?
Did y'all not watch the outro? He address that again
What about electron clouds around a nucleus? But thats probably not considered a wheel.
@@gluonic I we talk about a subatomic scale I would consider the spin of electrons,protons,neutrons and all the standard model particles as wheels
People always bring up hotels & offices, but those buildings always have chairs in them, most commonly using rolling chairs, which have 5 wheels. Typically a hotel room will have 2-3 doors per room, and at least 5 wheels.
If those are wheels, Then a membrane gated channel is a door. Therefore: there are more doors.
Was thinking about that too. I think the sheer number of bacterial and sperm cells still dwarfs the channels that are actually gated. I could be wrong tho
Office buildings have chairs with 4-5 wheels, and usually more than one chair per room, so that's at least 10x as many wheels as doors. Stores generally have more shopping carts than they do doors, and that's 4 wheels apiece again. For every hotel door there's a piece of luggage with 2-4 wheels. Everywhere you have doors you have something with more wheels.
May I present the option for cell membranes, when the cell membrane moves to accommodate a cell’s receptor being activated. Since there is material moving out of the way, personally I would rule that as a door
not to mention gated channels
10^30 still beats it lol
@@cryotimber don't bacteria have cell membranes too, and wouldn't they have a lot more openings/channels/ports which could be considered "doors" than their flagella "wheels"?
@@cryotimber There are roughly 10x the number of bacteria as there are cells, so in that sense, yes. But, a single cell enacts endocytosis dozens of times upon its surface, meaning that there would be more than 10x the number of “doors” on the surface of a cell. The exact number would vary by cell type.
He did mention that at the end.
I was kinda expecting electrical switches to be a part of the situation, their mechanism is just a door that when open doesn't let the electricity through.
Which would technically make transistors doors.
@@a2d and there are billions in a single phone chip
Theres no moving parts in a transitor though. They use current to control how much electricity is let through. How the fuck would a moving part that small ever even last more than a few momths before breaking down?
@@robertharris6092 The transistor technically is moving electrons between different "slots" in silicone to open and close it
Think about neurons!! Doors win
People keep thinking cars have the same number of doors and wheels, but if you look inside the car I think there are far more wheels in an engine than doors
My guess before watching the whole thing, more wheels, Hotwheels cars alone, there must be several times more of them than actual cars and they each have 4 wheels and no doors.
But have you seen containerships? Lots of doors and almost no wheels. But on the other hand a shpping container full of wheels would be a lot of wheels as well too. :D
Good catch, I hadn't even thought of hot wheels
Drawers have multiple wheels on them... A gear is a wheel, as are many valves, just imagine the number of gears in the world
@@xraceboyex would valves count as doors though?
@@jacksonbarker7594 Good point, would likely count as both, much like revolving doors
just going by how Kyle defined a wheel.. the vast majority of doors feature wheels (as he defined wheels as something that can freely turn on an axis) and door hinges, at least pretty much every common one, features at least one mechanism that would fall under that definition, so even without turning towards biology, wheels still win by a landslide
Hinges and axles are the same mechanism.
2:54 one thing you forgot to factor in is that’s out of all of the dogs in America. You’re trying to figure out how many are actually pets so that’s right on point that’s actually really good because there’s a lot of animals that are not yet pets they’ve yet to be claimed.
Despite the answer, I can't help but feel there's still a lot of doors yet to discover in this debate. If a wheel can be described as something that rotates from the center, then can't a door be described as something that has limited rotation or is hinged on the outer end of something. A door could also be described as an opening that can be blocked or unblocked, can it not? Do switches technically count as doors. I just think about all the microscopic electronics in billions of devices.
Are gills doors? Are mouths doors? Are sphincters? Without going microscopic, i think by that definition doors win.
If we stay non-organic, i think wheels win because of all the gears and belts in machinery
If a door is a device to regulate passage from one location to another, then transistors and diodes are doors
As well as protein pumps in cell membranes
Pores are doors!!
A door is just a very advanced wheel.
I think we need a more precise definition of "wheel." "Circular and rotates about an axis," includes a whole bunch of things that probably shouldn't count. This broad definition allows for things like screwdrivers, electric motors, lazy-susans, and yes, flagella. Most importantly, though, it includes hinges, which makes it almost impossible for doors to win.
Eh. Screwdriver doesn't really roatate. Its a tool that you twist. Hinges also don't rotate a full 360°. I think in this case, rotation has to be the devices primary function. I also believe circular would mean the devices diameter would be larger than its thickness/width. A cylindrical phase motor doesn't generally fit that description. Although broad, I feel like it's also very specific and doesn't require thinking too much outside the box. I like that youre thinking creatively tho 😃
We can all agree that rotating doors are the most common, and since the definition of "wheel" in this video, a classic door count as 3 wheels with the little rotatong things that attach them to the wall and gave them they're rotating ability
12:25 how I feel about most of the choices I need to make.
Ok, but what about doors and wheels we consciously interact with? I feel this version better connects to the actual question.
Most likely doors since hotels, stores, houses, motels, etc
On average I think there’s more doors in a house than wheels on a car
@@ToxicNoxic yes but I would argue a lot of machine require tiny little wheels, and the production of toy cars alone can blast the number extremely high. If you take an office building, there are probably more wheels alone on all of the chairs than all the doors in the building.
If you're gonna include organic wheels, you better include organic doors like literally any pump in a cell like efflux pumps or sodium-potassium pumps. Wouldn't those be considered a door into the cell too? Plus there's more of them!
didn't watch to the very end?
@@holdintheaces7468 Nah, but now that I have, sodium-potassium pumps are more like doors than channels. They open to the right chemical reaction and close too lol.
check my comment, I tried to work it out!
Even if the question was manmade doors or wheels, im 100% certain its wheels
Depending on how you define a "door", and a "wheel" this could go either way. I often do estimates like this, and I am sometimes surprised by how accurate those estimates are.
Exactly, like if you included valves in your definition of doors.
@@amosbackstrom5366 i always say the awneser is this. the stricter you are with the defection of doors and wheels the more wheels win the looser you get with the definition the more likely doors is to win
Are tiny transistors also doors though? Wikipedia says there are 10^22 MOSFET transistors in the world, which I think makes them more competitive if it doesn’t win the challenge.
Transistors are solid state devices though - no part of them physically moves.
If we theoretically had a waterfall function as a door and opening it stops the flow of water then managing the flow of electricity for transistors is effectively analogous to the opening and closing of transistors.
@@21Trainman in sci-fi, doors are sometimes shown as forcefields in binary on/off states with no moving parts.
@@littleratblue thats not a door. Thats a doorway with a barrier.
@@PirateDion a waterfall cant function as a door.
your deffinition of wheel could arguably include the hinges of every swinging door, and every sliding door certainally includes wheels as part of its guidance mechagnism.
Before watching the video I had actually answered wheels a few weeks ago. They are a common part that varies in size. The fact that they can come in accompaniment to doors and are likely used within machinery almost certainly guarantees a higher number. I can't imagine how much higher but doors have limited utility so we need only so many
what is a door if not a flat panel mounted to WHEELS?
@@misdelivereddishwasher1011 you could look at a hinge as a type of wheel.
@@ATSaale exactly my point yes thank you.
@@ATSaale actually, i deposit that wheels are only wheels if they both utilize an axle AND contact a surface with their own. the surface of the wheel must be utilized without joinery or adhesive or it is a hinge.
I think the only way doors win is if you stretch the definition of door and count transistors as doors as a single cpu will have hundreds of millions of transistors to billions each
Someone else pointed out ion channels. There are an order of magnitude more of those than flagella
Theres no moving part in a transitor.
so early it’s still listed as unlisted for me
How?!

As soon as he started pondering biological wheels I knew where that was going, lol!
I'm disappointed, though, that there was no mention of all the revolving doors that ARE wheels!
Under your definition of doors, however, cell openings do count as doors because they aren't constantly open and instead slide or open in a manner of ways to let stuff go in and out of the cells. And even if every cell only had one of those entrances it'd still be more than the wheels you counted because every bacteria with the wheel has to have one and every bacteria without one will also have one. This is also not counting all the other cell types that exist.
In all seriousness, my first thought was about utilizing scaling in programming to give the effective contributions of multiple variables. Super important stuff!
Unless I'm missing something, my instinct is to say wheels will be more plentiful due to how many different mechanisms use wheels, even doors.
EX: I do warehouse work a lot, and giant bay doors use 12+ wheels along a guided path to move up and down securely, same with the roll up doors on trucks, usually 10+ wheels locked in a guided path
what till you start to think of ball barrings as wheels in side of wheels man
By applying the same principle one could consider “natural hinges” like joints as door parts, that would increase the amount of doors dramatically
True, but the number of wheels is still bigger
@@maxwilson7001 are you sure humans alone would add 100s of billions for joints alone
@@himedo1512 You're right, they would add 100s of billions. Wheels would still win, though, because in every human alone there are 39 trillion microbes. And that's not even mentioning the bacteria on earth and in animals. There are *so* many wheels.
@@maxwilson7001 i suppose that's fair. But i personally think its irrelevant as its disingenuous to call either a wheel or door
@@maxwilson7001 If we are allowed to count biological wheels we are allowed to count biological doors. Protein Channels can open and close, and lead into a container (that being a cell). even if every cell only had 1, per human you have 30-40 trillion doors. Correct me if im wrong, my biology is a little rusty, almost all if not all bacteria also use protein channels aswell. Almost all is little bit more than half and when factoring in bacteria thats mainly the only number we need to look at.
Even when he was giving examples of why people kept switching sides, Wheels were a clear win. Every Lego wheel, hotwheels wheel, SHOPPING CARTS, etc, vs doors from a hotel or office? It's not even close, with or without the bacteria. The few hundred doors in an office building are nothing to the potential thousands of wheels at every chair at ever desk! Office chairs can have anywhere from 4 to 12 wheels!
I think its funny when people bring up hotels offices and hospitals. They don't relize that a lot of the furniture and equipment has wheels
Immediately after hearing the question, my gut instinct says Wheels.
“Doors” require structures to exist and serve a very particular purpose. For something to be considered to be a “door”, it has to be “reclosable passageway” between 2 different areas.
“Wheels” are a more vague concept. Literally any cylinder that rotates on an axle can be considered a “wheel”.
Generally speaking, the more vague a concept, the more numerous the things it can apply to are.
:Edit: After watching the video, I remain convinced Wheels will still win even if we further restrict the definition to artificial ones only, as per my original comment.
I like your footnote at the end of the video with the openings in cellmembranes might potentially be thought of as doors, and would then dominate wheels, but by the defenitions earler they are more like channels.
The defenition of a wheel was "A sircular frame capable of freely rotating about an axis". So this includes spinning planets, stars, galaxies. They are made of atoms that form a frame that does rotate about an axis. Fundamental particles like electrons and quarks does not fit this criteria as they do not have a frame. They just exist as they are as their own entity. But protons, neutrons and atoms does have a frame as they are made up of their smaller parts. And thus could be considered wheels when spinning.
So you ok with counting spheres as a wheel but not channels as a door? doesn't seems right to me. But yeah if we count atoms then wheels win
@@fistsofsnake5475 you can also count stars and planets as they are round and freely
spin on an axis
@@-BigTMoney- again spheres not wheels
@@fistsofsnake5475 By the definition given, sphere are wheels, if you are adamant they are not make an actual argument. Conveyor Belts use sphere rollers, I have driven cars with sphere wheels, Goodyear makes them I have seen motorcycles with sphere wheels, ball transfer units use sphere wheels. sphere wheel are common when engineering. High agility forklifts use them.
Look up omni wheels.
Let me ask you this if you needed a whee that could go on the X and Y axis what shape whould it be?
If you have a 3d sphere and looked at it in only 2d what shape would it be?
@@-BigTMoney-
cars moving on bals not make balls wheel. Unles you thing caterpilars used by some ehicels are wheels too?
And why i don't think spheres are wheels? Because they don't have established axis, as you wrotethey can roll in all direction
Hold on just a second, if you define a door as an easily openable barrier, taking some deviation from the above definition, similar to the flagella, then all microorganisms, cells, and all of the other biological entities on this planet have way more doors than wheels. Also, if you say that atoms are doors because they can block electromagnetic signals and can be changed to have different blockings of different electric signals, similar to doors, than the amount of doors are so unimaginably high. Doors for life, my friend.
Could we not say that any cell membrane is a door? Thus putting doors ahead by far?
In my basement I've found 36 wheels and 16 doors.
Wheels are round, fixed to an axle and are intended to and actually do allow and object rigidly attached to the axle to travel over a horizontal surface without sliding at the point of contact. (Excludes bearing, and simple cylinders)
Doors being a 1.Solid object of roughly planar shape 2. that separates two non-solid spaces when it's plane contains the normal vector, and 3. is intended to and does either moves and join the separated space either or (a) by pivoting on one or more hinges, (b) sliding along one or more parallel tracks or (c) to allow human movement between spaces, (Excluded books, drawers, hinged lids(which separate spaces only when it's plane is perpendicular to the normal vector)
What about oven doors?
@@KarldorisLambley Are vertical in the closed position, and have a hinge, and indeed count as doors.
Ground floor, I count 28 doors, and 2 wheels.
Garage and driveway - I count 42 Wheels, and 6 doors. Total count of my house - 80 Wheels, and 50 Doors. I think Wheels win, but my house may just be weird.
@@WorBlux I see. Human movement in your definition can include only motion of a part of a human ie. Their hand in and out of a cooker. Thanks for clearing that up for me. DA
I mean, when you REALLY think about it, you need to ask which ones you need MORE of. You don't have spare doors lying around, and you certainly don't have doors mass produced for daily use. Im saying this before watching the video, though.
EDIT: BOOYAH WHEELS HELL YEAH
by that logic any sphincter would be a door, when really it's a tunnel that closes.
@@Roboshi2007 what does that have to do with mass production???
3:16 This might be the most meta call-to-action I've ever seen
Life did evolve a wheel, there's basically one used in ATP synthase in mitochondria
Edit: lol right after I wrote this you got into the flagellum part, aren't there similar DNA used in both? Or did I just imagine that being in lectures about the evolution of the mitochondria.
In sliding doors, you need many little wheels
Think about the small wheels, doors are usually big. So, there are more wheels
why? they could just be sliding on the ground.
@@aurelia8028 sounds very inefficient
What if you consider cells' membrane proteins as doors? They can open and close, they have a frame, some type of moving mechanism and allow stuff enter and leave a space which is the membrane
Because of the extreme example you gave of wheels, I tries to think of an extreme example of a door. And I think you can co sides your mouth as a door; it is a thing which can open to reveal a compartment, and then you think of all the animals on the planet with mouths, all bugs, mamals, fish, everything, then 8 would say it's possible there are more mouths on earth than 10^30 so then there would be more doors.
I was thinking for something else biological that can be considered a door, and your heart valve could be called a door, they are a flap that opens and closes to let things through, then think how many animals are in the world with hearts. Using these examples it's almost definitive that there are more doors than wheels.
Bugs make up about 40% of the animals on earth. We'll make that 33% for easy maths.
10^19 bugs add 2x(10^19) for everything else. That's only 30^19. Even if we say bugs only make up 10% of life on earth (which is insanely low). That's 10^20 total animals.
Even if every animal had two mouths, still only 20^20. Not even close to 10^30.
@@SendarSlayer Every animal on earth does have two mouths. Around thirteen if you're going to call it what it is; a sphincter.
There are many, MANY more doors then wheels.
Transistors on a processor. Valves in motors including molecular ones, including on bacteria.
There aren't even close to 10^30 animals with a mouth on earth.
However if you count membrane bound transport proteins as doors, that would definitely be able to contest the number of flagellated bacteria, as the majority of cells have multiple of them.
To be fair though flagella are much closer to actual wheels than transporter proteins are to doors, since those typically don't have any hinges or sliding motion.
@@DarthObscurity If you want to start calling things with No moving parts doors I think you've lost. If you want to do that, I say every atom is a wheel.
Parts move around a centre point in a continuous motion. That's a wheel right?
@@SendarSlayer Doesn't create it's movement though that comes through interactions with other atoms and forces.
Dang I think that shows it, the flagellum is gonna do it, I do think the numbers are closer than you expect because of the very tiny doors that make computers work, the transistor. If we cant control electrons by allowing them to move or not move with tiny doors then I couldn't type out this comment. The number of transistors in the world is pretty big currently at 1.3×10^22 and could overcome the wheels eventually as we keep making them smaller.
he also kind of ignored his cell membrane comment from the beginning concerning the parts of the cell membrane that open and close to let material pass through them and whether or not they should be counted as doors or not.
@@monsterking7676 I mean at that point, arnt concentration gradients doors?
This feels like a win by technicality and not by the spirit of the original question
I’m actually interested in the fermi estimation based on doors as openings in cells 😅 [edit …I commented at what I /thought/ was the end of the video lol]
One of the most entertaining science guys out there. Farkin' hilarious and very learny.
2:58 Ive never been this happy when im wrong by 45 MILLION!
What if the earth suddenly became tidally locked to the sun?
By defining a door as a sliding opening to a container, you also open the box to the mouth and anus argument kyle....
People have 13 sphincters throughout their bodies lol
Hinges, doorknobs, and lock tumblers are wheels. Most doors have multiple wheels on or in them, and most things that have both have at least as many wheels as doors - so wheels.
If you really want to push the definition, we can include every orbit, every accretion disc, and - although it's kind of a naiive way thinking about them - every electron. To get even more abstract we can account for quark spin, meaning _every particle in the known universe_ comprises a minimum of three wheels
Have you considered the potentially dozens of rotating bits (wheels) inside of essentially *_all_* power tools.
There's an easier way to get to the answer: When you get to the point where you the two choices seem to keep equaling each other, ask which needs to be replaced more? Wheels need replacing far more than doors do in any example, since the wheel is the moving part with more wear and tear -- doors mostly just sit there. Our capitalistic culture will have more inventory of wheels in stock than doors simply to meet demand. That is enough of a difference to at least make a choice if not an estimation and doesn't require you to delve into molecular machinery.
Using those definitions for doors and wheels, the hinge of a door contains a wheel, the caasters of a sliding door are wheels, etc. Sure there are doors that would not contain wheels, but they are relatively rare, and wheels that contain a door are also rare. Ergo, more wheels than doors.
I'm so glad this got done. I remember watching the debate on this live and just kept thinking it would make such a good video. Kudos!
edit: Also, I work in a pork plant, and even if you include all the employees' vehicles and houses (just the doors) there are still about 100 times more wheels in the plant than doors in the plant, all the vehicles, and everyone's houses. So I think wheels definitely far outnumber doors.
edit 2: I feel like the answer was a bit of a cop-out. I think all of us in the stream were thinking of man-made wheels and doors, not naturally occurring ones inside of organisms. We need a follow-up video!
I would add to the definition of a door that it has to fit a specific creature or object and either be used or designed for such. Cause as it stands windows for example count as doors and that doesn't really sit right.
With the dog estimation while you were looking up, my brain was screaming YOU FORGOT TO ACCOUNT FOR SOME PET OWNERS HAVING MULTIPLE DOGS lol. I would have assumed 1.5 dogs per owner, for an estimation of 82.5 million, pretty close.
critique: the echo effect to make it sound like the facility is vast just makes you sound more alone.
But could you count sweat glands on our skin as doors? Most creatures have glands of some kind or mouths that could be counted as doors, oh many of them also have eyelids.
What about all the bottles and containers that have a type of door.
What about all the zippers that are in clothes, bags.
Cells have pores that could be counted as doors and I found it really easily by writhing "do cells have doors" :D
7:11 VSAUCE answered this back in 2012. A biological wheel would have to be a separate living entity that eats, sleeps and poops independently from the main body, which is incredibly impractical.
The winner is simply whichever you define more broadly. Wheels or doors.
It's always easy to answer an impossible question when you can also define the terms however you want. You could just as easily say "a wheel is any circular object rotating on an axis" and call the earth a wheel, or say "a door is any solid material that can be opened and closed to provide access to a space" and call a window or a camera shutter a door.
What about something like a voltage gated sodium or potassium pump in axons. They have “door” like qualities. They rotate on a “hinge” (protein hinge) and open and shut the ion channel. But also what about ATP synthase (in mitochondria) it rotates about an axis like a wheel. Just some food for thought.
I always defined wheels as Round, and made to roll on, and doors as objects that open and are made to walk through
By that definition cabinet doors aren't doors
For the dog as pets answer, if he'd have thought about people who own multiple dogs to keep the other company he would've been right on the money
Sodium-Potassium pumps in cells. EVERY cell has MANY. Every valve in every organism like in lungs, digestive system, cardiovascular system (yeah that one’s a much lower order of magnitude but still wanted to point it out. Nonetheless, just the pumps are over an order of magnitude more than flagellas)
I love how freaking detailed we got over literally one of the dumbest, most useless questions I’ve ever heard 😆
It's not dumb if it makes us question out definitions of everything
As a door advocate I would like to say that they built Machu Picchu without the use of wheels. And if you are bringing a bacteria's bottom on the table, I would like to point out that a birds wing is basically also a door....so there!
When you look at a car you see 4 wheels. When you put a bomb under that car and detonate it to see what’s inside you’ll be showered by wheels. A transmission is all wheels, pulleys for the belt system is all wheels, alternator, connecting rods, even the volume knob on the radio, it’s all wheels. Wheels are king.
People also often forget cabinet doors in their guesstimations.
Legos also made kind of doors so that’s basically a lot
It’ll always be wheel just because it’s a more simple thing than door. Since it’s a more simplistic mechanism, there will just be more
It has to be doors. If we're including cabinet doors, I have a few dozen in my apartment alone. Even if we're counting tiny wheels like the ones on a drawer railing, I don't think I even have half that.
"90 Million dogs" Me not knowing how much people are in the USA: "I was, 900 Million Off"
What about action-potential doors in cell walls. How many of those are there
The dogs in the US estimate would have been much closer if Kyle had considered that many dog owners get more than one, so they keep each other company.
That depressing moment when you finally have the answer to a question no one is talking about anymore…
