The thing about the resonance, what people usually don't want to know.

Kimmo Huosionmaa

Have you read Kalevala? There is a character name Vainamoinen, who played kantele, what was made by using the skull of the fish. That thing might cause the resonance inside the human body because the bones of our skeleton start to vibrate with the sound of that musical instrument, and this thing is very painful to experience because the bones can be broken like some crystal glass.

When we are talking about resonance, we are meaning the phenomenon, that the resonating piece would transfer the wave movement to every piece, what is made by using the same material. Or otherwise has the same resonance frequency, what means that the sound, what faces the surface of that material would start to vibrate it with the sound. This will cause the effect, where the glass or other material will be broken by the vibration. Resonance is a very dangerous thing because if the metal net inside the house starts to resonate, even the biggest houses can fall by the small loudspeaker.

This is one way to think about the resonance. But when we are thinking about the cases, where the musical instruments are made by using the bones, those instruments are extremely dangerous, because they are putting bones in our body to resonate, and this thing causes horrifying pain, because the bones would start to break by the sound. This is the thing, what we must understand when we are thinking about resonance. If the loudspeaker is connecting to the wrong system, it will create the voice, that would be very painful. The thing, what is used in this kind of tests is the horn of the narwhal.

This whale uses its horn for targeting the voice, and in those tests, the horn has been hanging on the roof, and then the high power voice would be targeted to it. The thing would be something, what we don't want to face. When we are thinking of the hero of the national Epos of Finland Kalevala, and it's hero Vainamoinen, this man used the kantele, what was made by using the skull of the fish. This instrument would cause the resonance inside the human skeleton, and this is why this kind of things are dangerous.

The new 3D printers are coin-size systems.

"The tiny device could enable a user to rapidly create customized, low-cost objects on the go, like a fastener to repair a wobbly bicycle wheel or a component for a critical medical operation. Credit: Sampson Wilcox, RLE" (Scitech, Tiny Titan: MIT’s Revolutionary Coin-Sized 3D Printer Fits in Your Pocket) Researchers created a 3D printer that is coin-size. That kind of printer can create things like microchips. But it's possible. Those tiny 3D printers can also work in extremely large-size projects. In simplest models, the 3D printers are positioned on tracks. The 3D printer itself is the tool, that can be part of the modular production systems.  There are visions of high-temperature metal printers installed on the gantry cranes. That makes those crane printers that can make even ship-size things. The crane that the printer controls can move back and forth and the printer can move horizontally. This kind of thing can turn the crane into a high-temperature 3D printer, that

Quantum computers and ultra-fast photonic microchips can danger even the most secure communication.

"Quantum computers could pose a major security risk to current communication systems in 12-15 years with their exponentially greater speed and code-breaking ability. (ScitechDaily, Today’s Most-Secure Communications Threatened by Future Quantum Computers) Quantum computers can break entire binary cryptography. And that makes all communication unsecured. That is one of the greatest threats in quantum computing. And this brings the arms race to the quantum age. The quantum computer can create codes that any binary computer can break. But the quantum computer can also break old-fashioned codes. And that makes it an ultimate weapon and sabotage tool.   Quantum computers can change the measurements of the ammunition in factories by changing the system calibration. Or it can delete databases from the opponent's computer systems. This thing can delete all SIM cards from mobile telephones. In peacetime, the hackers that operate using quantum systems can steal the names of the counter-

Electric power innovations. Fuel cells in aircraft and solar panels over Arizona canal.

  "ZEROe teams powered on the iron pod, the future hydrogen-propulsion system designed for Airbus’ electric concept aircraft." (Intersting Engineering, Airbus's ZEROe: First engine fuel cell powers up for hydrogen flight) Electric power innovations. Fuel cells in aircraft and solar panels over Arizona canal.  Airbus Zero is a testbed for fuel cells that are used in commercial aircraft. The problem with aircraft is always noise and pollution. If the aircraft uses electric engines. That decreases noise levels and cleans the air, especially around airfields. Lightweight solar panels that can be installed on the wings and body of aircraft can give electricity to electric engines. And they can extend an aircraft's operational range.   The thing that makes this kind of system interesting is that the "flying cars" or cheap VTOL aircraft can use them as a power source. The hydrogen power cells can give energy to electric aircraft at night time. And that makes them m
