Why Did It Take So Long To Invent the Wheel?
Hugh Pickens writes "Wheels are the archetype of a primitive, caveman-level technology, and we tend to think that inventing the wheel was the number one item on man's to-do list after learning to walk upright. But LiveScience reports that it took until the bronze age (3500 BC), when humans were already casting metal alloys and constructing canals and sailboats, for someone to invent the wheel-and-axle, a task so challenging archaeologists say it probably happened only once, in one place. The tricky thing about the wheel isn't a cylinder rolling on its edge, but figuring out how to connect a stable, stationary platform to that cylinder. 'The stroke of brilliance was the wheel-and-axle concept,' says David Anthony, author of The Horse, the Wheel, and Language. To make a fixed axle with revolving wheels, the ends of the axle have to be nearly perfectly smooth and round, as did the holes in the center of the wheels. The axles have to fit snugly inside the wheels' holes, but not too snug, or there will be too much friction for the wheels to turn. But the real reason it took so long is that whoever invented the wheel would have needed metal tools to chisel fine-fitted holes and axles. 'It was the carpentry that probably delayed the invention until 3500 BC or so, because it was only after about 4000 BC that cast copper chisels and gouges became common in the Near East.'"
because it wasn't invented in america.
That's why it took so long to invent the wheel.

Since there was no patent law, there was no incentive to innovate, and technological progress stagnated.
THAT'S why they're always telling me not to reinvent it...
But also the wheel needed an application. While people lived in small villages, there wasn't much of a need to move things over large enough distances to require vehicles. And when things were moved across the countryside, there may not have been surfaces for wheels. Most of us could build a wheel and axle to use on a modern road, but how about building one for a narrow, muddy track through the forest?

We'd either have to pay tribute to the patent maker, be sued for it, or be driving around on octagons.

Its because everyone was spending their time in the bath, getting hair cuts and discussing what to do with their wealth after making leaves the official currency. What's more, the story glosses over the most important part of the process, deciding what color the wheel should be.

Bah - except you don't...
There are many ways to construct a wheel/axle combination that don't require precision tooling...
Use of slots rather than holes... Forked branch style notch rests.. etc
Extend the axle past an over size slot then mount a disk tied/lashed.pegged over the end for alignment
Older systems used a wedge arrangement in the axle to give an adjustable attachment/brace for the end bearing plate
Durability of these however might continue to be an issue
...it doesn't take long for people to reinvent the wheel all the time.

That's a bit of wordplay- same story as to when the boat was invented: it was whenever someone had wood, and noticed that it can take a load (and still float)
Now a shaft going through a firm hole that stays in place while it rotates and has a wheel attached yes, it is a different kind of invention, but the concept of "wheel" was there already- heavy things were carried by rolling them onto logs. True, not the most elegant solution, but beats the hell out of having your slaves die of exhaustion.
Puns aside, what puzzles me more is a) why kites where not used more excessively for lifting objects, especially since the sail was known (perhaps they just dinae think of it?) and b) why there was no industrial revolution after Ancient Greece since they had steam engines

The anthropologist Marshall Sahlins has written some interesting things about early society. One thing he notes, is that there was an "original affluent society" of sorts - hunter gatherers from 40,000 years ago often worked less hours a week than, say, a worker in a Foxconn factory making iPhones, or even say a network administrator being paged at 3 AM because the network is down. From the hunter gatherers of then, to the few surviving bands in South America, Africa and Asia today, the hunter gatherers often have to work less hours per week to provide for themselves than the people with their hands on the most sophisticated technology we have available today. One may ask why the wheel should be invented in the first place.
Another interesting thing Sahlins points out is this. Occupy Wall Street and the like protests against "the 1%", which in many cases are heirs of the type portrayed in the documentary "Born Rich" or the like. People, like say, the UK's royal family, where it has been so many generations since anyone worked, that those ancestors are lost in memory. In other words, there are people who do no work, and are living (and often living quite a high life) off of the wealth they take from the work time of those who do work. This would not be possible without surplus. If I am a hunter gatherer, and all of the work I do is to feed myself, my children, and perhaps the very elderly in my band, there is no surplus left over. But once the agricultural revolution happened, there was inevitably surplus, and thus the possibility of a class of priests, kings and such who did not need to work. Sahlins point is the agricultural revolution was not needed for this surplus to exist. Hunter-gatherers CAN work 80 hours, and support idlers who do not work. But hunter-gatherers simply don't do this - everyone able bodied works. And as many anthropologists etc. have pointed out - the agricultural revolution is a mystery, because the techniques of hunting/gathering had advanced sufficiently by 10000 years ago that they were far superior, in the short-term back then, then farming. Farming back then was a much worst way of getting food than hunting/gathering. It took many, many years to breed say teosinte grasses into maize/corn, domesticate animals and that sort of thing.
Why should the wheel be created. I am watching the TV debates and hearing about "job creators", which I guess are rich people. Then I watch birds flying around and realize they don't need anyone or anything to create jobs for them, they are self-sufficient. It's the majority of humans who in are social structure are dependent on these wealthy "job creators" to create jobs so that they can survive. A bizarre concept which early hunter-gatherers didn't have to worry about either - they were as free as birds in being self-sufficient and not dependent on these technology-empowered "job creators". No wonder the wheel wasn't invented for so many years.
Is that in the new world, the wheel and beasts of burden were only used in limited capacities. The Aztecs, Mayans, and Incas were on par with western civilizations in other ways, though.
What about indoor plumbing and sewage? I always find it hard to believe people were willing to put up with the smell of shit 24/7 up until not very long ago. The technology was already there for over a thousand years but nobody applied it to the task.
Hunter gatherers would have had plenty of use for a wheel, if you were to use your argument. Mankind may have settled down into small villages eventually, but they still went on days/weeks long hunting trips. You wouldn't want to carry a large prey with you on a sled or on your shoulders, if you would have a cart of some sort to transport it on. I'd say your argument doesn't really hold up if you look at it a bit more closely.

Old wheels just transfer sliding friction to a controllably-greased axle. Wheel 1.1 is different in principle, with friction-free roller bearings in the axle. "Grandpa rolled things on logs, so put the logs in the bearings".
At the museum we saw they had round disks with holes that they kept on sticks and cords for hundreds of years.
Also some kind of rolling pin thingy.
They never clicked to the idea of the wheel tho.

Dodn't you read the wikipedia article?
Hero of Alexandria's Aeolipile had nothing to do with "Ancient Greece", it was invented/constructed in what we call the first century AD, during the ROMAN era, about a thousand years ago. The Aeolipile was little more than an executives desk toy, made to show a principle. There was no way to take a drive off it and the system has little torque and so can't power anything.
The Romans, let alone the Greeks before them didn't have the technology to cast and forge large iron objects essential to constructing the parts of even an ineffective steam engine. Look at the history of guns, a "similar" pressure vessel system. Gunpowder entered Europe in the Middle Ages and at the beginning it was only possible to cast small iron guns, often full of fatal (to the gunners) flaws. Some cannon were even made of wood, bound with iron hoops like a barrel, perhaps why a gun barrel is called a gun barrel...
The technology to cast large bronze and iron artefacts, with any degree of precision only developed in the 15th-16th centuries (again mainly driven by war), and the tools needed to manipulate large masses of metal took even longer to appear, so its not surprising that what we call the industrial revolution showed its first glimmerings of life towards the end of the 16th century and matured slowly during the 17th and 18th centuries, towards the end of which, the steam engine appeared.
Industrial revolutions depend on a lot more than a Graeco-Romano philosophical desktop toy!
They would still be sued, as Apple has shown that you can patent shapes. And an octagon still has the look and feel of a circle, so they are doubly fucked.

Bullshit. I saw a documentary way back in the 60's that clearly showed the wheel and axle existing in the stone age. It was called The Flintstones.

As time goes on and we discover new things, I put less and less trust into what others have determined to be true about the past and what goes on outside of earth (the two things we have not seen yet). There is too much speculation and a lot of the theories are based on too many other things that are theories themselves. Estimates of what matter exists and how much of it is "out there" are all over the place. some millions of times less or more then what others think.
...researching the wheel usually isn't a priority for me. Chariots are useless units.
Oldest example of wheel and axle ca 5100 BC. And it is a safe bet older examples will be found. By the way, the Wikipedia article usefully points out taht the value of a wheel is greatly diminished without well constructed roads to run it on.

Your stated assumption that wheels were number 1 on to do list is really bogus, surely no. 1's were the blade, the club, the dart, the needle, the sack, the pot, medicine and let's not forget fire. and language.
Besides it's quite possible that simpler wheel designs were developed earlier and died out in obscurity.
That was due to energy density. Our industrial revolution was accompagned and facilitated by an increase of energy density : coal usage.

This is probably also the reason the History Channel is so confused by the ability of prehistoric peoples to move very large rocks. It turns out, it is very difficult to build a wheel and axel that is strong enough to support thousands of tons. In modern times, that means that there is a huge incentive to use smaller rocks and fasten them together. For more primitive techniques, pulling more weight just means having more people to do the pulling.
How long have people used grinding on jewels? It is true that life without good tools has limits but a bit of sand and a drop or two of water can be used to cut a precise hole in stone even if wood is used to push against the sand slurry. And once one has a nice hole in a rock that hole can be used to grind and axle of hardwood or even of stone. I suspect that the wheel was not valued as there are so few natural places that a wheel can be used. Sand, mud, loam, fertile soil, rocks or even hills and gullies all do a pretty fair job of making a wheel useless. I wonder if there are old drawings of cooking where an animal is turned on a spit over a fire. That is a crude form of a wheel and if a primitive person could understand cooking by rotating a pole over a fire then he probably understood the concept could be used on the ground to move things about. One thing that is obvious is that ancients all over the world had great skills at moving large, difficult objects. I don't think we are out of design battles at all in striving to find better ways to move objects over land.

Why is the wheel considered so important?
I suspect it's a western-only or maybe American-only thing, as the Japanese do not seem to consider it "the most important early invention", at least to the extent Americans do.
It was really strange seeing "the wheel" used as an example of "the beginning of technology" in a lot of American cartoons, which you don't see in Japanese ones. I kind of suspect it has something to do with American car-centric culture, and them assuming primitive wheels were as important in their time as they are today.
What countries do you guys have experience in, and do they consider the wheel as important as Americans do?

Actually, the concept was employed by Poul Anderson in his story The three-cornered wheel, in which a constant width polygon (the simplest being a Reuleaux triangle) was employed to circumvent a religious prohibition on circular objects.
There is also a three-dimensional equivalent (constant-width polyhedron). A version of the Reuleaux triangle with rounded corners is occasionally encountered in industrial design. People keep reinventing it, just like square wheels, etc.

It's because they invented beer first and they were smart enough to worry about drinking and driving..
Besides, hauling stuff is what slaves were for. And the reason people learned shipping/sailing first was because that was where the people lived and how they traded. I think the wheel was probably invented to deal with a problem: either piracy on the water forced goods to start moving over land. Or exotic and valuable materials needed to be hauled across areas that did not have a shipping route.
The wheel was invented to solve a problem. Not because its cool.

Actually, the wheel in circular shape is just the most common type as it is pretty fit for a frequently found - albeit boring - shape of surface to ride on, i.e. a flat surface, in an over-simplified manner called a "road". ;-)
If the surface (the "road", in a more general sense) given had been designed properly (and skilfully), a square wheel might just be the right shape for a smooth ride on it:

I would argue that wheels (for transportation) are more or less useless without roads, so that the important invention was the road network. If that is true, it is no accident that the wheel was invented during the first period of large empires, as they built road networks, nor that wheel use tended to die out after the fall of the Roman Empire, when the Roman Roads fell into ruin.

A wheel isn't very useful if you don't have a smooth enough road to roll it on. With what passed for roads during most of human history, a wheel just wouldn't be practical. Instead, they used a travois, which basically meant dragging a couple of poles behind a horse with your cargo lashed to the poles.
The wheel too closely resembled Apple's patent on rounded corners, so it was squelched.
You can see from their fairly good records the wheel (and horse) was not used their first thousand years of dynasties, expect on toys. Not for the large pyramid construction, unless you count rollers. The Hittites, possible the first Indo-European group in the area, used horses and chariots as did lots of other Indo-European groups. (Moses happened after the Hittites, so THAT movie is accurate.) The Indo-Europeans may have co-developed the cart and horse labor technology.
Wheels are worthless unless you have decent roads. In order for the invention of a wheel to be worthwhile, you need a decent, flat path, without too many ruts, to drive your vehicles across. Meanwhile the Incas has excellent roads, but since they ran up and down mountains, wheels might help you for half the journey, be become a liability on the other half.
Computers are useless. They can only give you answers.

Because they're worthless without some sort of, well, fucking road ???
If you had no experience with wheels, I think you would intuitively believe that the friction at the axle would be just as bad as a sledge sliding on the ground. What's really required to understand how a wheel works is how the wheel reduces frictional force at the wheel tread by acting as a lever. That's not a simple concept.
While a wheel freely turning on an axle would be quite an achievement, it's quite easy to attach two wheels to a single axle, then allow the axle to turn under the platform by trapping it between two blocks, or inside a "bearing," such as a block of wood with a notch in it, with the notch side fixed to the platform.

if you think of all of the reasons that I use wheels today, I doubt that most existing back then. People didn't tend to travel, there either wasn't anywhere to go in your daily life, or it wasn't more than a few football fields. and without an engine, or chains, or another six inventions, wheels wouldn't help. so you still need to hook it up to an animal, and just riding the animal is easier. until you need to haul something. certainly now adays, there are loads to haul, but back then, you didn't farm that much at a time, and blacksmiths didn't make a thousand horseshoes at a time.
so still you're six inventions away from make it worthwhile. you needed distances to cover and loads to haul. it's not that there weren't any, it's that they weren't everyday for every person, and dancing to make it rain was more important than getting the water from the local well.
I say that considering things in the short-term back then - and I stress that idea of "short term" which I mentioned - going from hunting and gathering to agriculture makes no sense - it is a mystery. Yes, in a long, long, long-term view, going from A to Z might make sense, but it made no sense from back then in the short term. One must also keep in mind that my example of teosinte grass cultivation took place in Mesoamerica, so explanations of this must encompass things like that happening as well.
You say "Why the heck would the agricultural revolution be a mystery?" This makes me assume you are about to explain the answer to the mystery which has puzzled anthropologists for over a century. But you don't, you say "it seems inevitable". This is not really a satisfactory explanation of all the issues involved that satisfies me.
People keep seeming to keep missing this point. My post used the qualifier short-term and talked about the mystery. You point to hunter gatherers from 15000 years ago, and then to agricultural communities of 7000 years ago with domesticated crops and animals. You say "What's more smart - to go hunt wild game, or to find and raise domesticated animals and plants you can eat without having to expend yourself?" and you also talk about a time machine. Yes, a time machine bringing you from 15000 to 7000 years ago might make sense, but what happened between those 8000 years? That is what made no sense. The first farmers had to expend themselves far, far, far, far more than hunter gatherers. You talk about domesticated animals and plants, but there WERE no domesticated animals and plants. THAT is the mystery that has puzzled anthropologists. You say it is no mystery over the long term, but you missed where I said short-term. It may not be a mystery over the long-term, it certainly is a mystery why it happened in the short-term back then.
"To make a fixed axle with revolving wheels ..."
They could have started making wheels with a revolving axle like in spinning, potter wheels, wheelbarrows. And suddenly all the explanation does not make much sense.
That makes me think of the Darkwing Duck episode where the dinosaurs had the rubber roads and the stone wheels... it's a massive misapplication of energy and work, even if it is intellectually interesting.

When discussing why it took so long to invent wheels it is interesting to note that the luggage with wheels was invented in 1972 by a Mr Sadow, who initially had a hard time selling his idea to luggage manufacturers. If you went to a station or an airport before this time you would have seen everyone lifting or perhaps dragging their bags. In retrospect wheels and wheeled bags seem obvious, but it is not obvious before you have seen a lot of other people use it.

Yes, the greeks created steam engines, but it took a long time to learn how to create engine that don't explode that often.
Anyway, the Industrial Revolution wasn't caused by the steam engines. The engines surely had an important paper later, when industrialization was gaining ground, but the revolution started before. If there is one prominent cause of the Industrial Revolution it is the sistematic accumulation (and testing) of knowledge we currently know as "science". And the writters of the time were quick to impersone it on the figure of Newton. Of course, the greek had examples of things that were like science. But it wasn't generalized.
I think that throughout most of human history, there were no wheels because there were no roads, not even any more-or-less flat enough surfaces to make a wheel worthwhile. Of course, wheels still work on bumpy trails, but not much better than travois or similar apparatus. The wheel needed to be invented simultaneously with the invention of roads on which to use them. Once foot trails became wide enough, long enough, and smooth enough, then the wheel became a worthwhile invention.
Native American's invented wheels as well but they only saw use on toys. http://www.precolumbianwheels.com/ It's easy to verify that wheels were invented independently by multiple cultures.
Since we now know that it was the invention of beer that spurred the invention of agriculture,
It must have been the need for reliable beer wagons which spurred the invention of the wheel.
Why does Slashdot keep posting these blurbs by Hugh Pickens? He re-uses entire phrases and sentences from the links, but they are presented as original words with no quotes and with fragments from one link merged with another. He should at least attribute his blurbs appropriately.
I know, hindsight bias, but it doesn't seem as bad as the summary makes it sound. Why couldn't you make an axle square to fit into the wheel in the middle, and just add a few more sides on either side, e.g. octagonal at the sides? It wouldn't be perfect, but it would be an improvement.

People or group of people during that time probably could pull, drag or carry most of the things, I think. Or, They are not handling anything heavy / working on something large scale that is beyond their capacity to pull, drag or carry.
The reason all those things bother you when "survival camping," is that you aren't used to them. Modern society has made you soft. Clearly people in the past were different: if they weren't, why would some have been fine living as Eskimos when surely word had filtered back to them about the paradise to the south where clothing wasn't needed and food abundant and there were plenty of soft, sandy beaches to sit on. Some people must have just not been all that bothered by conditions that we would consider brutal. Hell, I can't even understand why people live in American cities where it snows when there are so many more comfortable places to live! But people do.
Wheels are not useful in a lot of terrain and on a lot of ground. It takes special circumstances to actually make the wheel seem worthwhile. But once there is a critical mass of wheel users, then people will start to build roads and change the environment.
I guess no one mentioned sand and bow-drills as a methodology for producing the sort of holes needed for axle bearings? or that once those same drills were made to produce holes in, say, in a hunk of sand stone, that these holes in sandstone couldn't be used to draw out relatively well tuned axels that would fit the holes made with the same drill?
Either the cave-dudes were seriously short of imagination, or these researchers were, not sure which....maybe both heh
rolling boats on logs?
Otzi the iceman was projected to die at 50 due to arterial clogging if he had not taken the arrow in his shoulder. That's healthy?
And here I thought it was because the Cavewoman wouldn't stop bitching about cleaning the cave, and hunting brontosaurus and such.

Is that they required a wheel to be invented and attached in order to function.
The wheel was available all along, problem was that ROADS had to be made first. In Africa, where I come from, there was no wheel before the arrival of Europeans but they did make sleds from a "Y" branch of a tree, and hauled by cattle. A wheel needs a flat surface to roll along on, without roads they are useless.
In all the talk about wheels, no one seems to have mentioned using them for grinding. Whenever you want to make lots of big bits into little bits, uniformly and with minimal effort, it seems a wheel would be useful -- more so when the effort can be supplied by oxen rather than by your arm.
The Ancient Egyptians had a kind of boomerang too. In fact we all use it, daily, but as the letter "C"!

" The letter C evolved from the Egyptian hieroglyph of sharp hunting stick a sort of boomerang shaped cutting tool."
Cool, ain't it!
No one person invented the wheel. The wheel is just manifest. And we certainly don't have a clear enough vision of antiquity to run around making declarations about who invented it or when.
