Technology can help make our world simpler and more advanced. Digital advances can support and accelerate sustainable development, e.g. B. reducing extreme poverty, reducing mortality, providing sustainable agriculture and decent work, and achieving universal literacy.
Digital technology itself is an electronic tool, system, device and resource that can generate, store or process data. Examples of digital technologies closest to us are social media, online gaming, multimedia and mobile phones.
Digital technology has evolved faster than any innovation, reaching about 50 percent of the world’s population in just two decades. By improving connectivity, financial inclusion, access to commerce and public services, technology can help a lot in life.
One of the things that has helped the development of digital technology is education. Digital learning is any type of learning that uses technology. This can happen in all areas of learning, such as B. in digital physics technology, which we will discuss in this article.
The word “digital” comes from Latin – digitus, finger – and refers to one of the oldest counting tools. When information is stored, transmitted, or passed on in digital form, it is converted into numbers, which at the most basic machine level are “zeros and ones”.
The definition of digital technology includes all electronic devices, automated systems, technological devices and resources that generate, process or store information.
The difference between analog and digital technology is that in analog technology, data is converted into an electrical rhythm with multiple amplitudes, while in digital technology, information is converted into a binary system, that is, zero or one, with each bit representing a symbol of two amplitudes is .
Digital physics technology is a digital technology that incorporates physics into the process. Some examples of digital physical technologies that we actually encounter in everyday life.
Starting from the Pramana Research Journal titled Physics Behind Digital Technology written by Sreelatha and Showrilu, various forms of storage such as floppy disks, hard drives and CDs are some examples of digital physics technology applying the concepts of magnetism, laser physics and optics.
Semiconductors and quantum mechanics, both concepts in the natural sciences, paved the way for the development of integrated circuits. The invention of the Giant Magneto Resistance has made it possible to shrink hard drives in recent years. In order to be able to read data from compact hard drives, sensitive reading heads have been required in recent years. The sensitive read head can read data from compact hard drives used in laptops and some music players.
Digital physics technology, in the form of a CD, focuses an infrared laser on a metal disc to indicate “holes” and “earth” representing “0” and “1”. The return signal is modified by the photodiode sensor. The scanner divides the photo into small pixels. This creates an array of binary digits, each representing the brightness and color (RGB) of the pixel. In display devices, the concepts of cathode ray tube, liquid crystal and plasma physics play an important role.
Based on the principles of physics, there are amazing new advances in imaging technology. This technology allows physicians to look inside the body to watch vital organs at work, identify blockages and growths, and even detect signs of underdeveloped disease, all without the trauma of exploratory surgery. As a result, remarkable advances in the diagnosis of syncytial diseases have been made in the history of medical science.
Image processing is a technique for analyzing, enhancing, compressing, and reconstructing images. Pattern recognition is a process of information reduction. The assignment of visual or logical patterns to classes is based on the characteristics of those patterns and their relationships. This technique is widely used in astronomy, medicine, industrial robotics and remote sensing by satellites.
In the case of digital signal transmission, the concept of total internal reflection is used in an expanded manner via optical cables. Other techniques such as microwave transmission and IR transmission are also based on fundamental concepts in physics. Their ability to transmit large amounts of data will be measured at the limits of physics.
Computers actually have digital physics technology too, because the sending and receiving of signals works according to the principles of physics. They convert analog radio waves into digital signals, represented by electrons darting across the board.
GPS navigation is sensitive to nanosecond calculations derived from Einstein’s general theory of relativity. PET Scan uses 3D body imaging made possible by particle physics. Even the World Wide Web at your service is a creation of physics, conceived by Tim Berners-Lee as CERN for the transmission of large physical data files.
