Today we woke up with sad news knowing that the American engineer William English, a fundamental part of the research and development process of the first computer mouse, died last July 26 due to respiratory failure at 91 years of age.
William English’s legacy as a co-inventor of the mythical “mouse” joins a long list of great creations that have made giant strides in the world of technology in recent years. From the glorious network of networks to the increasingly widespread 3D printing technologyThey have all entered our lives to change them forever.
Therefore, from Tuexperto, we have taken the opportunity to look back and remember what some of these great advances have been with a personal selection of 5 inventions that marked a before and after in the technology sector. Let’s go there!
The computer mouse or “mouse”
We use it every day, although perhaps not so much laptop users. Be that as it may, all or almost all of us have used this peripheral at some point in our lives while we used to use the computer to play, work or navigate.
Everything a must whose origin dates back to the 40s of the last century. Specifically, in 1946 the trackball came to light, a precursor system of the mousse that included a cursor controlled by a trackball that allowed moving the digital information displayed on the screen.
It was somewhat later, in the early 1960s, that William English and Douglas Engelbart, who worked at the Stanford University research center, designed the first prototype computer mouse as we know it today.
The device was built inside a wooden box, and consisted of perpendicular wheels at the bottom, a button at the top, and a cable. A design something rudimentary that was subsequently polished until its world presentation in 1968.
What can we say about the Internet that has not already been said. The Internet is one of the great landmarks of humanity, beyond having revolutionized the world of technology and that of telecommunications. A revolution called to change society to unsuspected limits, with no point of return.
His insight has been so extensive and so profound that it has forever changed the way we relate to and work with. A semi-anarchic information transmission model, which even today companies and states alike have not been able, or have not known, how to put a stop to it.
It was the 1960s. Various private and public organizations had been trying to connect one computer to another for some time, until the Bell company (today renamed AT&T) achieved an unprecedented milestone: they were able to transmit binary data (zeros and ones). ) over a copper telephony cable and through a modem.
It was then that the Pentagon gave order to create ARPAnet, a network that would link several nodes in the form of a network to first link some universities and then cross the entire country from coast to coast.
GPS technology is found today in many devices. Another of those miracles of technology that begin their journey in the framework of a military investigation.
Although it was originally known as the Navstar Global Positioning System, what we know today as GPS was conceived in the Pentagon, with the launch of the first GPS satellite operational in 1978.
This system, as we said at the beginning, It was designed for military uses, especially for monitoring tasks. It was not until 1993 that the United States Government declared that the system had full operational capacity to allow its use in other sectors, such as transportation, in 1995 under the acronym SPS.
Although we associate drones as a cutting-edge technological ingenuity, the concept of drone is quite old. Beyond the military robots that we see today, drones have been used for decades.
Since the end of the 19th century and throughout the 20th century, there have been several experiences with drones since the American Civil War, going through the two great world wars, of course the Cold War, until almost reaching our days, when the CIA begins to fly with drones in Afghanistan in the year 2000.
Athough it does not seems, war is not the only use we can make of drones. Fortunately, there are infinite applications in the field of conservation, rescue, infrastructure, distribution of assets, and even medical assistance.
Let’s not deny it, the mobile and its wonderful Internet connection are an inseparable part of our lives. Mobile connection technology improves at breakneck speed, the change from the first 2G networks to the new arrival of 5G being palpable, which the vast majority of users are already enjoying.
Not for nothing, the evolution of the mobile communication network has been strongly marked by each generation (the famous G), by assuming a paradigm shift in standards, technical capacity and new features that differentiate it from the previous one.
Another of the great technological milestones of our century, and that even today no one explains himself. 3D printers are here to stay, and their very existence is a revolution, allowing almost anything to be built at minimal cost.
The beginnings of 3D printers go back to the 80s, with some adaptations and advances on the concept of conventional printers and their inkjet systems. These changes allowed to transform the technology of printing with ink to printing with materials. Today, we can see a wide variety of applications of 3D printing technology, adapted to very different sectors.
