The Wheel
The wheel is a circular and mechanical element that rotates around an axis. It can be considered a simple machine, and is part of the set called machine elements.
It is one of the fundamental inventions in the history of mankind, for its great utility in the production of pottery, and also in land transport, as a fundamental component of machines. -

The electricity
It is the set of physical phenomena related to the presence and flow of electric charges. It manifests itself in a wide variety of phenomena such as lightning, static electricity, electromagnetic induction or electric current flow. It is a form of energy so versatile that it has countless applications, for example: transport, air conditioning, lighting and computing -

Printing
Printing is a mechanical method intended to reproduce texts and images on paper, cloth or other materials. In its classical form, it consists of applying an ink, generally oily, on metal parts (types) to transfer it to the paper by pressure. Although it began as an artisanal method, its implementation in the mid-fifteenth century brought with it a cultural revolution. -

THE WATCH
The instrument is capable of measuring, maintaining and indicating the time in conventional units (hours, minutes or seconds). Fundamentally, it allows you to know the current time, although it may have other functions, such as measuring the duration of an event or activating a signal at a specific time. -

THE COMPASS
The compass is an orientation instrument that uses a magnetized needle to point the Earth's magnetic north. Its operation is based on terrestrial magnetism, so it indicates the magnetic south that corresponds to the geographical north and is unproductive in the north and south polar zones due to the convergence of the lines of force of the earth's magnetic field. -
THE FRIDGE
they are devices used mainly in kitchens and laboratories, which consists of a thermally insulated cabinet, with a main compartment in which a temperature between 2 and 6 ° C is maintained and also, frequently, an extra compartment used for freezing -
The radio
It is a means of communication that is based on the sending of audio signals through radio waves, although the term is also used for other forms of remote audio sending such as Internet radio.Radio communication is the technology that enables the transmission of signals by modulating electromagnetic waves. These waves do not require a physical means of transport, so they can spread through the vacuum. -
THE TELEVISOR
It is an electronic device intended for receiving and reproducing television signals. Usually it has a screen and commands or controls. The television is the final part of the television system, which begins with the capture of images and sounds at the source, and their broadcast and broadcast by different means. -
THE COMPUTER
It is a digital machine that executes commands to convert them into convenient and useful data that are subsequently sent to the output units. A computer is physically formed by numerous integrated circuits and many support, extension and accessory components, which together can execute diverse tasks very quickly and under the control of a program
