Workshop on the first floor of the house. On the walls hang reproductions of paintings, drawings and drawings by Leonardo da Vinci.

There is a partially disassembled motorcycle near the wall. On the table is a shock absorber from the motorcycle. From the top of the shock absorber go two wires with terminals. A guy is sitting at the table, his name is Fred.

– Everyone is messing with your motorcycle. – Taking in his hands and looking at the shock absorber, asks his mom. – What about wires?

– I make an electromagnetic suspension. The magnetic cushion trains ride. What makes my bike worse? They have a magnetic cushion between the train and the road. I have a magnetic pad instead of a spring, between the upper and lower parts of the shock absorber. That is, between the wheel and the motorcycle.

– Than you are not satisfied with the usual suspension? – Mom puts a shock absorber on the table. – Everyone else is driving, and fine.

– Mechanical setting. On the go it is impossible to regulate.

– Why on the go? – Mother does not let up.

– When a passenger lands a motorcycle crouches. Reduced suspension travel. And what if you have to drive off the track on the roads. You will need to stop, take the keys and twist. And on my bike, the shock absorber stiffness will change by turning the knob. And the suspension travel will be much more. Watch it.

Fred shows the instrument on the table. On the table, one on top of the other, are two electromagnetic coils. The coils are put on a long rod with a stop in the upper part. The upper coil has the ability to move freely along the rod, up to the stop. Fred turns on the device.

– When adjacent poles of coils are opposite, coils are attracted to each other. Try to lift the top coil.

Mom comes to the device, and tries to tear the top coil from the bottom coil. She does not work.

– When the poles are the same, the coils repel each other. – Fred switches the polarity of the top coil. It slides upward along the rod, and hangs at a small height. – Try, push on the top coil.

Mom first lightly, and then with a force of pressure on the upper coil. A coil with more resistance goes down. She lets go of the coil. The coil quickly moves up, and a little walk up and down, stops.

– Push again. And try to keep her down.

She again presses on the upper coil, and lowers it down. At this time, the Fred regulator increases the voltage, and the upper coil, despite the resistance, rises up the bar.

– Take your hand off. – Says Fred, and reduces stress. She removes her hand from the reel. The upper coil hangs in the middle of the rod.

– Now get away.

Fred walks over to the dumbbells, and takes one small dumbbell disc. He returns to the table and puts the disk on the top spool. The coil under the weight of the disc drops slightly and hangs slightly lower than before. Fred slowly rotates the regulator, reducing the voltage. The upper disc coil slowly descends. Fred turns the regulator very quickly in the opposite direction.

The top coil with acceleration flies up the rod. Coil, flying up to the stop, stops abruptly. By inertia, the disk flies up and, hitting the ceiling, falls to the floor.

Mother instinctively bounces off the table. Plaster falls from the ceiling. Fred, as if nothing had happened, continues to explain.

– Perhaps the bike will be able to jump. Not so high of course.

Fred picks up the disc and puts it in place.

– Jump then why? – Mom asks stunned, looking at the place on the ceiling where the disk hit.

– This is a side effect. Although it may be useful.

Mother walks to the table and looks at the metal disk.

– What is it?

– Gyro.

– What for?

– In order that the motorcycle could better keep balance. In any extreme case. The gyroscope works like this, look.

Fred picks up the bike wheel. He keeps the wheel between himself and his mother.

– You hold that end of the axis. Put the axis on your index finger and hold it big. This end of the axis I hold. Now raise or lower, each end of its axis.

Raising and lowering the ends of the axle, they tilt the wheel, then one way, then the other.

– The wheel bends down. But! It is worth the wheel unleash.

With his free hand, Fred spins the wheel hard.

– Take your thumb.

Mom gently removes the thumb. The axis remains to lie on his index finger. Fred raises his side of the axis. The end of the axis, lying on the mother’s index finger, rises up. The wheel rises, maintaining the horizontal position of the axis and the vertical position of the wheel itself.

– Nobody holds the other side of the axis, and does not lift it. She rises herself.

Mom is at a loss. She runs her hand over her side of the axle, and over the wheel itself, thinking that this is the focus, and there is a thread that supports this side of the axle. But he cannot find any invisible thread. Fred lowers the wheel to the previous level.

– Hold the axis. – He offers again.

Mom takes on her side of the axis. Fred once again spins the wheel. He removes his fingers from his end of the axis. The wheel is held on one mother’s index finger. Wheel retains upright position. Fred shows his hands.

– See. The wheel does not bend. The wheel steadily holds the given position. The same will be with a motorcycle. With a working gyroscope it will be impossible to drop it.

Mother raises and lowers the rotating wheel with one finger. Fred goes on to explain.

– The wheel will not only hold a vertical position, but also steadily hold at any angle to the horizon.

– Doing any nonsense.

Mother leaves and enters the computer system unit into the room. – This is a computer based on a neural network. We were given out for training. Need to talk to him. Giving him a job. And do not forget about the lessons.
