Magnetic Amplifiers (ART572E)

When we analyze the history of electronics, we usually sequence technologies with passive components, valves, transistors, and the era of integrated circuits overlooking quantum electronics. But isn't there anything missing in that sequence? That is what we will see in this article. We will travel to the past, to the time of valves, and discover that there was already a similar technology, which was somewhat forgotten, that of magnetic amplifiers.

Do you know what a Typotron is? (ART565E)

The "zoology" of electronic components presents very interesting facts for readers who are interested in "archaeological studies" of this science. Not only what certain components did is interesting, many of which disappeared, but also the assigned names that followed a certain logic. We have already dealt with other articles on components ending in "tor" and we see that a large number of them have not reached our times. In this article we deal with components terminated in “tron”.

Makers, Inventors or Scientists (AT546E)

We are experiencing a strong transition in the way of life for people all over the world, accelerated by the pandemic that is plaguing us at the time of writing this article. There will be a disruption, in which our old customs will be totally forgotten, and we will move on to a new era in which customs will be different. In this article, we focus on what, in our view, this will mean for science and technology.

Energy Storage Technologies (ART561E)

In the past, the only simple and most used way to store energy was through batteries. Batteries have evolved, allowing ever greater amounts of electrical energy to be stored, but at the same time new forms of energy storage have been created, improved and are now very promising, some with important practical applications. In this article, we focus on these technologies and with special attention to their application with forms of energy generation which also evolve day by day, such as solar and wind power.

Back to the Future (ART423E)

With advances in technology, especially those involving quantum physics, we are increasingly realizing that a time travel may be possible in the future. Maybe it is not the way the well-known film "Back to the Future" preaches, as we're just crawling into the understanding of its phenomena. But there is something behind it. In this article we make some interesting considerations on the subject.
