What is common between the ball of robots and the world exhibition of 1889?

The expression “The Nail of the Program” arose after the 1889 world exhibition in Paris, at which the opening of the Eiffel Tower, which was quickly dubbed the nail, caused a worldwide sensation. The tower turned out to be a masterpiece and the next 40 years in the world could not build anything like it.

Few people know, but the construction of the Eiffel Tower is not the limit of 19th century engineering; it is just a leap above the head - engineers could not think of anything like eiffel either before or 30 years later (until the Shukhov tower was built in Moscow in 1922). And all because Eiffel stole his election from nature.

Remember the picture from the textbook? the tibia of a person can easily hold a weight of one and a half tons. But how?

The design of the Eiffel Tower is based on the scientific work of the Swiss professor of anatomy Herman von Meyer . 40 years before the construction of the Parisian engineering miracle, the professor investigated the bone structure of the femoral head in the place where it bends and enters the joint at an angle. And while the bone for some reason does not break under the weight of the body.


Thigh head incision. In the spongy substance, oriented structures are visible, corresponding to the functional load on the bone.

Von Meyer discovered that the head of the bone is covered with a sophisticated network of tiny bones, thanks to which the load is miraculously redistributed over the bone. This network had a strict geometric structure, which the professor documented.

In 1866, the Swiss engineer Karl Kulman put the theoretical basis for the discovery of von Meier, and 20 years later, the natural distribution of the load with the help of curves calipers was used by Eiffel.


With the opening of the exhibition, the world was shocked by the technical superiority of France over the whole world. The French went into the lead by two generations!

Forty years later in 1939, the He-178 , the first aircraft with a turbo-jet engine, took off. It was possible to insert the turbine into the jet engine thanks to the special shape of the blades of the Eiffel Tower type. There, by the way, the whole story with these blades - each of them is as complicated as a space station but is grown from a single crystal! Google it.


The modern gas turbine engine OP16 is built around “Eiffel technology”: the aerodynamics of a single-stage centripetal turbine was maximally worked out to achieve a wheel efficiency of 90%. The turbine blade section has a “Eiffel Tower” type design with a strong root part and a relatively thin and light peripheral section that allows reaching high peripheral velocities (about 700 m / s) on the periphery of the blades without an extremely high level of stress. At the exit from the guide vane, the speed of a uniform flow of heated gas is about 690 m / s. Since the difference between the two speeds is insignificant, in the peripheral section of the turbine blades there is no flow deceleration and due to this increase in temperature.

This is the way of technology of slanting supports in the history of engineering science. Eloquent in her time built the Eiffel Tower. The French really needed to create an engineering miracle and they created it, being ahead of time by 40 years, when the technology found massive use. Now small “Eiffel towers” ​​stand in each plane and rotate the turbines of each power station - that is, they are everywhere present in our life.

Simply put - the world exhibition of 1889 was the magnifying glass of a kind of time machine. Indeed, the vocation of exhibitions is to demonstrate the future. If you, of course, know how to see. Now imagine that you can purposefully dedicate the exhibition to the nearest future and show its prototypes - this is how you get the ball of robots.

In the future at an exhibition you get from a threshold - on a tatka you come into the room where you are surrounded with robots, tens of various robots. About how in Moscow 2040th.

Visitors are greeted by a big-eyed Japanese robot.



He recognizes the children and starts hugging them.



To the left of the entrance is a class of robotics, here parents take children away from their parents and teach them how to assemble a robot from lego by designing nodes on a computer.



Adult entertainment a little further - a hand with a conventional ballpoint pen draws a face that it recognizes from a webcam. His name is Paul and he gives out one portrait every 20 minutes.



Right next to the super cute Belek seal Paro, who loves to be touched.



"Reasonable lamp", a kind of irony over the theory of the need for artificial intelligence for robots. The robot and without intelligence to cope with the work of a messenger or servant.



Or another example - the robot Tespian glows like a Christmas tree and plays scenes from star wars for roles. Reacts to visitors and waves to all photographers at the sight of an iPhone.



Tespian makes the most impression on girls.



ruthless Japanese ping-pong trainer - no one can beat off its delivery at maximizing complexity.



Even the beauty of the Tootsie soloist does not blind the robot!



This is the children's section, here the robots are assembled by schoolchildren from designers for the simplest games.



And this is a whole corridor with shops of robots - on the right there is an exhibition of paintings by the brilliant Eric Joyner .



These hands are blind, but extremely gently grope visitors to determine their gender and age. Between the hands of the device is similar to kinekt.



Pushkin's head reads his own poems for secondary schools. Ominous valley in all its glory.



Handheld scanner at work - after the bust of the girl will print on a 3D printer.



The super pen is a 3D pen, it writes in space with the same plastic as the 3D printer. Worth 4999, you can easily draw a statue of the Eiffel Tower.



On the balcony, meanwhile, its own dzhigitovka. This device also has a skull on the knobs, I think it would look great on a biker get-together.



Robot titan scares the public. In fact, this is “just-only” a fancy computer-controlled exo-skeleton, inside of which is a living person named Nick Fielding. Since 1987, he has been collecting exoskeletons and conducting speeches in them. It should be noted that with the Russian he is not very good, but this makes the performance only funnier.



If we talk about personal predilections, then my favorite is the French robot Nao. He understands voice commands, tells stories and plays a guessing game, in general, the coolest gift for any child on any occasion, the price is just like viburnum frets - 350,000 rubles. It is curious that inside it has only the intel atom 1, bGHz. I think in five years it will shrink every ten, if not a hundred - now these babies are released in tens of thousands.



Only here you realize that in some ways children and robots are clearly on equal footing:



By the way, the maykrasoft everywhere put xbox3b0 with titanfall - xbox one is not yet launched in Russia, you have to be content with little. The game is very dynamic by the way - you run along the walls, jump in huge robots - everything is ten times more dynamic than in my favorite battlefield. Maybe this console so many girls?



From the street, the sounds of heavy metal are beginning to be heard, which means that the Compressorhead concert has already begun!



METAL!!! (actually grunge)



I hope you are already ashamed that you are missing the main geek event of the year! But you still have a chance - the exhibition will run until June 15, and if you hurry, then at 20:00 the last concert compressor head, you can still buy tickets on the website .
