Technology has made great strides in recent years. It’s going at an impressive pace, and keeping up with it is not easy. Think of smartphones in their many forms of telecommunications technology, from 4G to 5G. Optical fibers, a simple glass structure, have enabled high-speed wired internet in our homes at affordable prices using the emission of small amounts of light: photons. Not only that, IoT and Industry 4.0 allows us to make our systems smarter, and to control them remotely using ultra-efficient wireless technologies to improve our functionality in both local and industrial visibility. The emergence of artificial intelligence and quantum computers will be able to solve many questions related to science in the field of relativistic quantum mechanics, in chemistry and biology, and in studying the incoming signals from the universe in an attempt to answer the following question: Are we alone in the universe? But first of all, why are we “forced” to stay on Earth and find it difficult to “simply” leave and visit other “near” planets that belong to our solar system? As you know, getting out of the atmosphere requires enormous energies, and it takes a long time to reach nearby areas (like the moon). Have we been punished? The mere fact that the speed of light exists and the impossibility of reaching it is actually a punishment. Everything revolves around quantum mechanics. Think quantum computers, which we’ll see in detail, or basic electronics with transistors and integrated circuits, which are appropriately assembled according to electrical engineering laws, and allow smartphones and wearables to function, and then think of all the electronics from our increasingly numerous, connected electric cars. The purpose of this series of articles is to shed light on the main topics (in my opinion) of both pure physics and technology. Starting with quantum mechanics, we’ll end with energy. At the end of each article, you will find a short list of articles and books to dive into the topic. Obviously, in some cases, a high level of physical and mathematical knowledge is required, but I have tried to simplify and give everyone the opportunity to approach quantum physics and the different aspects of technology. Some technical knowledge, as you will notice, needs clarification. I fell in love with electronics at the age of twelve, when I first opened a television valve and then made a simple RC circuit (engineers will understand what I’m talking about). Since then, I’ve enjoyed every minute of the adventure. After my engineering studies, I continued my other passion, physics, my scientific and technical journey, during which I met scientists and engineers from many countries and had the opportunity to discuss various topics. Knowledge of science and technology, seeing a scientist and engineer, or vice versa, allowed me to see things from a research perspective (why do gravitational waves bomb us?) As well as from an engineering perspective (how do we detect gravitational waves?). With this series, I invite you to take a tour of my time machine and go through the different stages of diving into physics and technology. are you ready? Are you sitting comfortably? The car is a DeLorean, but believe me, the interior LED headlights, LCD screens, and audio will explain it all. And I forgot to mention that it does not contain parking sensors. We’ll start with quantum mechanics. Why quantum mechanics? Our best description of the nature of the particles that make up matter is described by this still misunderstood science. The holy grail of any matter is quantum mechanics. We’ll then see how quantum computers are created and relativity is explained, Einstein’s theory, which has changed and changed physics with the discovery of gravitational waves and space travel in the future. Is time travel possible? Why did we go to the moon? Artificial intelligence will lead us along the way to discover the existence of other planets. Artificial intelligence will be the new Einstein. So we’ll talk about AI from various aspects, including the industrial aspect. After this broad overview focused primarily on physics, we will move to technology in the field of telecommunications, particularly electric vehicles, microelectronics, and energy. We will apply the concepts of quantum mechanics to analyze what the technology has been able to achieve from a microscopic perspective. With the rise of cloud computing, the increasing adoption of artificial intelligence, and the increasing use of big data driven by the Internet of Things, the layers of data communication have never been faster and more numerous, and wired and wireless communications have not been as engaged as they are now in both devices and devices. Software challenges, which require more efficient electronics (think the upcoming 5G and 6G). One of the issues that will affect us all is energy. There is a lot of energy around us, free energy or open source energy, as I like to call it, just applying physics to collecting large amounts of electricity for each application to power or recharge various electronic systems. Physicists are trying to discover the scientific meaning of all this energy that affects us every day; Engineers want to harvest them, to be able to operate their machines in an environmentally friendly way. We want our devices to be free of batteries. What are we waiting for? How do smart grids make energy management effective? For several years, the need for energy efficiency in distribution systems, along with the widespread integration of renewable energy sources, has increased the demand for new technologies driven by the emergence of new materials. Power electronics is the key to tackling many of the efficiency challenges. The emergence of new microelectronics to support high transfer speeds with 5G and fast charging will see the participation of new broadband semiconductors such as gallium nitride and silicon carbide. GaN and SiC will see widespread use in areas such as electrical mobility, 5G, audio, and the entire powertrain sector. Technological development is accelerating its applications, and silicon will soon leave the high-energy field. Refueling at home: DC wallbox is a fast charging solution for your garage and can be connected to the PV system in your home. Power devices will improve efficiency and performance in automotive and energy-saving applications, as well as in all high-voltage industrial applications. Robust, efficient and cost-effective energy appliances with high energy density play a major role in enabling global economies to effectively reduce carbon emissions. Climate change is driving the use of alternative energy sources, followed closely by vehicle electrification. The Covid-19 pandemic has increased demand for electronic devices such as computers, tablets, cell phones and servers to convert energy more efficiently. This trend will continue with the release of new technologies such as 5G devices and the entire Internet of Things. Managing energy transmission and consumption also remains essential for companies to cut costs. All of this is happening on a planet where there will be more and more people, more electronic devices, less resources, lands devastated by climate change, and more waste. Technological progress is the only weapon to advance humanity’s recovery and future. One of the good news about the coronavirus pandemic is that the crisis appears to be accelerating the shift from fossil fuel-based energy sources to renewables. As the energy ecosystem takes a green turn, the pandemic can accelerate this process. Economically advanced countries are implementing more ambitious climate policies and increasing carbon taxes, with an emphasis on a green transition to stimulate economic recovery. Increased sales of electric, hybrid and hydrogen cars will weaken the demand for oil. In conclusion, we will take a historical overview to understand the differences between the past and the near future. Are we ready for the upcoming technology? What role should education play? But wait, it’s not over yet; I’ll take you on a journey into a parallel fictional world where you’ll meet the four scientists who marked an era: Einstein, Maxwell, Newton and Tesla. In a mock encounter, they will encounter contemporary technologies and express their reactions and ideas about how our lives have evolved thanks to their inventions. Enjoy!
