World Wide Web Celebrates its 30th birthday

The World Wide Web idea was first introduced on March 12, 1989. Long before the madness of MySpace, Youtube, Facebook, and even Instagram, Tim Berners-Lee, a software engineer, worked hard on proposals about the project. called the World Wide Web.

The 33-year-old British computer scientist introduced his vision for computer networks stored in a document called "Information Management: Proposal" on March 12, 1989. His boss, Mike Sendall, commented that his vision was unclear but interesting. The following year, he was allowed to work on his presentation. Berners-Lee's vision of the worldwide web was actually born of frustration. During that time, computers have different information, and someone is forced to constantly get into different devices to get it.

He wanted to solve the inefficiency by building a hypertext database with typed links. He also wants the web to be a universal source of information and a place where people can find their own space to work, play, and socialize.

In 1990, Berners-Lee was able to create HyperText Markup Language or HTML., Uniform Resource Identifier or URI / URL, and Hypertext Transfer Protocol or HTTP. He also made the first web page browser and editor called "WorldWideWeb.app" as well as the first web server called "httpd." A few months later, he completed the first internet web page followed by letting people who were not involved in CERN in the young online world. It needs to be an open system if universality is the goal.

His vision, the world wide web, was finally available to the world in April '93. And today, 30 years strong, the whole world is enjoying the fruits of its hard work. Is this the most meaningful discovery of all time?

Wisdom Segment

I - In general, a gyroscope is a device used to maintain or measure the orientation of an object and its angular velocity, or in short, its angular position. Usually shaped discs or wheels, where the axis of rotation can take any orientation. According to the law of conservation of angular momentum, no matter how much the mounting has been tilted or rotated, the orientation of the rotation axis remains unaffected.

II - Dreadlocks are ring-like support structures that allow the wheel to rotate around one axis, and two or three of them are used. In case two, the outer gimbal functions as a gyroscope frame even though its axis cannot rotate and only has one degree of freedom of rotation. The inner gimbal, which is mounted inside the frame, has two degrees of freedom of rotation.

III - The gyroscope's rotation axis is determined by the axle, where the rotor is forced to turn it. The spin axis always lies perpendicular to the inner gimbal shaft. As a result, rotors can rotate in three dimensions. To further emphasize this concept, inserting a rotational force on one axis will produce an output rotation, following Newton's third law of motion.

IV - The front wheel of a bicycle is a much more acceptable example of how a gyroscope works: The front wheel circle will also turn left if the wheel rests from the vertical axis, which causes the top of the wheel to move to the left. In short, the third axis rotation (wheel rim) is a product of the rotation of the rotating axle.

V - The center of gravity of the gyroscope rotor can be in a fixed position, where it rotates on one axis while also tottering about the other two axes. Because of this mechanical freedom, the rotor can rotate in all directions with respect to a fixed point (which in this case is the center of the wheel).

VI - Not all gyroscopes comply with the standard model. In rare cases, the gyroscope frame may not be inserted, giving the rotor only two degrees of freedom of rotation. If the rotor is offset from the oscillation shaft, the center of gravity of the rotor may not always coincide with the center of suspension.
