# Period, Frequency, Natural Vibration are now the foundations of a new technology

Concepts such as period, natural vibration period, frequency, angular frequency, natural vibration frequency continue to be the most emphasized topics of the new period science world. He states that especially the world of science has switched to quantum physics of science in the new century. With the developing technology, frequency is expected to take place behind the most striking explanations and inventions.

## What is Frequency?

Frequency is a measure of how often and how many times an event occurs per unit of time (typically 1 second), mathematically speaking, it is the inverse of a period to multiplication.

Measurement
To measure the frequency of an event, it is counted how many times that event repeats itself in a certain time interval, then this number is divided by the time interval and the frequency is obtained.

In the SI unit system, the frequency is denoted in Hertz. One Hertz means that an event is repeated every second. If the event has a frequency of two Hertz, it means that the event repeats itself twice per second. Another way to measure frequency is to determine the time between repetition of the event, since the frequency can be obtained indirectly since this time is inverse to multiplication. The time between two iterations is called the period and is usually denoted by T in physics.

The note la, which is given as a chord sound to ensure integrity in the orchestra, is a vibration with a frequency of 440 Hz.
Human ears react to vibrations in the 20-20.000 Hz range.
Electricity distributed from the network is alternating voltage oscillating 60 times per second. AC 220V 60Hz warning on electrical equipment means that the device operates with 60 Hz 220 Volt alternating voltage.

## Period, Frequency, Natural Period of Vibration – What is Frequency?

To clarify the definition of the period, consider a pendulum motion or the motion of a rotating body around a circle.

Let’s answer the question of what is the period for the motion of the pendulum; Period; It is the total time it takes for the object that starts to move from point 1 to go to point 2, then reach point 3 through point 1 and return to point 1. In our circular motion example, the period; On the other hand, it is the time it takes for the object that starts to move from point 1 to return to its starting position, ie point 1, passing through the points 2, 3, 4 (or on the contrary 4, 3, 2) respectively.

### What is the Natural Vibration Period? What is Natural Vibration Frequency and Natural Angular Frequency?

What is the Natural Vibration Period? What is Natural Vibration Frequency and Natural Angular Frequency?
If we talk about free vibration before the concepts of natural vibration period and natural vibration frequency;

Free Vibration: If a system starts to vibrate when it is moved away from its static equilibrium position and can continue to vibrate without any effect from external environments, such vibrations are called free vibrations.

Natural Frequency: The frequency value that depends on the stiffness and mass of objects and structures and will continue to vibrate continuously in high amplitudes and in the absence of damping when vibrating at this frequency value is called natural frequency. The number of natural frequencies of a system depends on the number of degrees of freedom of the system, the system has as much natural frequency as the degrees of freedom it has.

### NeuraLink: Connecting Elon Musk’s human brain to a computer

South African businessman Elon Musk, founder of Tesla Motors and SpaceX companies, announced that they have founded a new company called NeuraLink and are working on technologies that will connect the human brain to computer interfaces.

It continues to be the subject of frequency behind the new generation technologies. Especially the electrical work of the brain and communication with frequencies is just at the beginning.
