Thirty-two metronomes that move apart are the pace of nature and footsteps

ByFlod

Moving multiple metronomas all at once will move apart at first, but eventually all the metronomes will interact with each other and tick the sound at the same timing .... The phenomenon called "synchronization phenomenon" is called. A movie causing this synchronization phenomenon using as many as 32 metronomes,Saitama University Faculty of Engineering Ikeguchi LaboratoryIt was published on YouTube by.

The table on which the metronome lined up on the platform is mounted is made to move by hanging from the left and right.


Touching the needle to the metronome more and more with your fingers ...


So that all 32 metronomes tick the sound.


All are moving apart.


After 1 minute, it is still broken.


Approximately one and a half minutes later, the pace was gradually coming ... ....


After 2 minutes, 32 metronomes tick the sound with almost the same movement.


Four minutes later, there are metronomes that move at the same timing like the armies.


Incidentally, we are also conducting experiments using 24 metronomes.

In this way, the pendulums mutually influence each other and different rhythms of vibration come togetherSynchronization phenomenonWas discovered in Europe in the 17th century and now medical devices and others are made using the nature of synchronous phenomena. The synchronization phenomenon is not only in the metronome, but it can be seen in many scenes in nature, such as frog singing, firefly light, human heart beat.

You can see the movie capturing the synchronization phenomenon of fireflies from the following.
