An Intelligent Speed Bump Uses Non-Newtonian Liquid (businessinsider.com)
turkeydance quotes Business Insider: A Spanish company has designed a speed bump that won't hinder slow drivers but will still stop motorists driving too fast. The speed bump is filled with a non-Newtonian liquid which changes viscosity when pressure is applied at high velocity. They've been installed in Villanueva de Tapia, Spain and there has also been interest from Israel and Germany.
There's a video on the site showing the speed bump in action.

Physics is bullshit anyways. God changes the viscosity.
A non-Newtonian fluid is one that doesn't follow Newton's Law of Viscosity. So that part is actually correct. However, it is most certainly not intelligent.
I am surprised that they didn't call it AI and have an whole article about how it would replace the job of cops.
Kudos to the guys who came up with this. Like all great ideas, once explained everybody can grasp it.
It's going to cost too much and not be durable enough. Regular speed bumps are extremely cheap and made of asphalt; slightly fancier ones are cheap and made of rubber and metal.
Also, if it doesn't hinder slow drivers, the people installing them won't be satisfied. Speed bumps are a tool installed by hateful people to make driving suck more; reducing the suck defeats the purpose.

Speed bumps have been called "sleeping policemen" or "lying-down policemen" in various parts of the world for decades.
Pain is merely failure leaving the body
It's patented by some spanish company, so you won't be seeing installations in the US any time soon. ;)
Anons need not reply. Questions end with a question mark.
I agree. There is nothing intelligent about a bag filled with cornflour and water. Anyway, it's a great innovation on the older (2012) idea of using the same sort of thing to patch potholes temporarily. See this: http://www.popsci.com.au/tech/...
I mean, if you have to be travelling at relativistic speeds, what is the point in that?
Add to it studded winter tires.
If builders built buildings the way programmers wrote programs, then the first woodpecker would destroy civilization.
These liquid-state speed bumps will never survive real world conditions. Solid-state ones, since well designed, work just as well. They need to be sufficiently long (> 1.5 m) and have a sinusoidal shape.
But looks like they're hard as hell to build and made of solid gold, because they're f*king hard to find.
It's "intelligent" in the same way there are "smart" phones. In other pedantic news - the sun doesn't set, the horizon rises.
"National Security is the chief cause of national insecurity." - Celine's First Law
You know, many generations of language reformers have tried and failed to fix the sloppy way humans naturally use language .
Perhaps the most famous attempt was in 1668 by Royal Society Fellow John Wilkins, who created a language intended as a replacement Latin as the universal language of scientific (then called "philosophical") communication. The first order of business was to get rid of all that figurative cruft and replace it with precisely defined concept-signifiers. The attempt, while attracting great interest, was a dismal failure. Exactly one paper was ever written in Wilkins' "philosophical language", an essay by Robert Hooke (of Hooke's Law) titled "The Universal Character of Pocket Watches".
The reason these attempts never go anywhere is human beings have a powerful, context-aware language processing computer inside their skull that effortlessly interprets fuzzy, associative and figurative language with near-perfect accuracy. Not absolutely perfect, mind you, but good enough that improving on it results in a language that so painfully awkward that it is impossible to use with anything like the perfection the creators envision.
This doesn't stop every new generation of pedants from trying, as most attempt are such irredeemable failures nobody has ever heard of them. The only one to have any kind lasting success was a theologian named Peter Mark Roget. His philosophical language was as useless as any of them, but the detailed concept index he compiled for it turned out to be quite handy for writers looking for just the right word.

Soft to the touch but can stop a bullet?
I wouldn't care about it being called "intelligent" except that not only is it technically incorrect but it's also a buzzword that gets thrown around far too frequently.
But it might be street smart.

The generic idea (different "liquid" specified) was posted on the internet back in 2001. Here.

Politics is Treachery, Religion is Brainwashing
That's the point: people use technically incorrect buzzwords all the time until the buzz is used up and then it's just another alternative meaning for the word.
Some time look up a list of dead metaphors, like "deadline". A "dead line" was originally a boundary past which a prisoner would be shot. "Deadline" as applied to projects was a humorous metaphor, but as with "software", it's no longer a joke; it's just a word.

That is not what "non-Newtonian" means. The google is your friend.

Newton did a lot of stuff, and got his name attached to a lot of things.
One of them is Newtonian mechanics. Another is the term "Newtonian fluid."
These are two separate concepts.

You'd be surprised what kind of impractical ideas people will try to get away with when looking for funding.
The bump's outer layer must be flexible. This automatically makes it more susceptible to cutting.

Newton got his name attached to more than one concept. Newtonian mechanics and Newtonian fluids are two separate concepts.

“He’s not deformed, he’s just drunk!”
As the saying goes - speed bumps are no problem if you take them fast. Like "washboard" roads this is really true, a car's dynamic suspension can even out the double bump if you moving fast enough.
But speed dips are another story entirely. Mostly these aren't really put in for speed control, usually it is for surface drainage, but they work really well to make people slow down. A memorable occasion I recall in one such town was a caddy that went into the dip excessively fast, and the front of the car pitched forward and hit the macadam with a shower of sparks, then rocked backed and the rear did the same thing, then the car rocked forward and hit the pavement again, with another spark shower. I doubt the driver did this again.

Whooosh, I think.

That's okay, neither a lot of drivers
“He’s not deformed, he’s just drunk!”
You do understand that you are supposed to slow down for speed bumps? Muffler damage I can buy, but bumper or rim damage kinda tells me you aren't using the speed bump properly. In fact they were probably put there just for you.

No, the earth rotates. How's that for pedantic?

Cab drivers NEVER slow down for speed bumps. The cab shocks are destroyed within the first few weeks on a new cab. The cab still rides great, even better than before. When you go full speed over a speed bump with a broken in cab, you can't even feel the bump. Time is money to a cab driver. I know, I drove one in Las Vegas.
So those security cameras will start getting a work out. I'm sure the mischief charges, destruction of property and vandalism will make you much more employable.
Architectural plans are like computer source code with a couple of differences: You only compile once.
So I read the article and have a basic understanding of the technology. I can see how "reversible" applies at the low level, but it is a poor choice for a description of this process. Adiabatic computing might be better, but people who have never taken thermodynamics probably don't understand that word. I'd suggest something like "No Waste Computing" or "No Heat Computing" might be a better description (neither is strictly true, but the potential waste heat is extremely low, i.e. just saying "low heat" doesn't seem adequate). My descriptions are not necessarily a better description in terms on understanding what is going on, but a description of what the benefit of the process is, which I think is more appropriate in this case.
Not necessarily. The whole thing could sit on a cushion made of the magic shit(TM) and retract.

Little known fact about Hooke: Isaac Newton hated him. Thought he was a right fucking twat.
The only reason the poor sod got the one about springs named after him was because old apple-bonce got a fit of the bloody flux and was on the privy a month.

i had an acura integra a couple years ago (it was one of the really old models). it actually got stuck on one of the bigger speed bumps and i had to push the car to get it off. speed bumps are bullshit.
That joke flew over him at light-speed I think.
Do you mean a solid shell resting on top of the bag of gloop?
That would just spread the force across the whole bag and negate the desired effect.

Yeah, I can see how you'd consider your calculator smart. You must think your goldfish is a genius.

Finally, somone that has some understanding. You'll note that the assholes that drive like tools over the present ones can drive just as fast as they always do. I reccomend over 100 mph, you know, because speeding makes the wimminfolk really horny.
But if these fools want to vandalize them, something more onerous might show up in their place.

How adjustable is the fluid/goo inside these?
The most annoying this I find about speed bumps is that you can't drive over them comfortably at the ADVERTISED SPEED LIMIT. These things are supposed to be used to discourage speeding, which means driving ABOVE the advertised limit, but that's never that case.
So can these be adjusted so that driving over them at 50km/h in a 50km/h zone will be a smooth ride, but when driving at 60km/h it'll harden?
Because fuck you if you didn't slow down before going through their town.

"Trump!!", the new Godwin.
I think an intelligent speed bump would look for speeding cars by means of some sensor (radar or so) and then raise some destructive concrete post right in front of the driver seat. It also may be anything a bit less destructive like nails or suchlike.
A really intelligent one would differentiate between authorized and non-authorized over-speeders.

the sun doesn't set, the horizon rises.
No, the earth rotates. How's that for pedantic?
Technically it doesn't just rotate, it rotates and translates. And in the meantime the whole system (sun and earth) is moving relative to the galactic frame, which is its self moving. So if you want to predict the exact time the horizon will come up to to block out the sun, you need to do a bit more than just calculate the time one rotation takes since the earth will have moved noticeably meaning that the suns relative position will be just a bit (slightly less than 1/356 of a rotation) moved from the previous day.
How's that for pedantic?
Not even close. A real pedant would tell us exactly how much the sun would move on average and probably take into account the slowing effect of the moon all in order to just tell us that the real dominant effect is that the person watching the sunset is going down relative to the horizon.
The same can be said of your body, and would probably be a greater improvement.

"Tough" in the context of material properties means neither of those things. Toughness is about the ability to absorb energy, not the ability to withstand pressure.
You are the one bullshitting. Non-Newtonian is a well known term that means viscosity varies as shear rate changes.
Fantasy and fiction both have a basis in reality.
Instead of a bump, it would open a portal and send the speeder to Unknown Kadath.

There are 2 groups of people you can make fun of on the Internet without fear of attack. The illiterate, and the Amish.
Yes and that's why there are no road signs nor street lights anywhere.
The video says speed bumps hinders even slow drivers, but it's only partially true. Speed bumps are made to make you slow down and work with your car's suspension, but many people stop just before going over it. If you're going too fast, your suspension will reach it's limit and it'll be a rough ride, same if you don't go fast enough and your suspension doesn't give at all. If you're going at the right speed, the suspension makes it almost smooth. Speed bumps neat pedestrian crossings could be replaces by those though.
You'll note that the assholes that drive like tools over the present ones can drive just as fast as they always do.
Prediction: the viscosity of the fluid will be such that you are required to drive below 15 MPH to ooze through it without a bump, in order to enforce a 25 MPH speed limit.

Atoms don't follow the law's of Physics, as the term is a misnomer. Physics and math attempt to understand the behavior of atoms. It is much like trying to understand a woman with logic. The moment we think we have it figured it out is the moment we become complete fools :-)
