Introduction Nuclear energy: between emotional debates and incomprehension, it is time to really understand what nuclear energy is, in what forms we exploit it, and future projects to face present and future environmental challenges. We will first explore the basic principles of this energy by looking at how an atom and its nucleus are made up. Next, we will explore our engineering techniques to harness this energy. And finally, we will understand what nuclear fusion consists of, its advantages and disadvantages, and the various future projects for exploiting this energy....

Today, we are tackling transistors, these small electronic components that have revolutionized the world of computing since their very first creation in the 1920s. What is a transistor, how does it work and why is it? what so important? And what is the future of transistors? Let’s explore this. The story of its invention At the beginning of the 20th century, modern electronics grew with the aim of better controlling the electric current applied to a circuit in order to build increasingly sophisticated machines....

Human success on the planet has been made possible thanks to our ability to communicate in the purpose of solving complex problems as groups. However, some groups have not always agreed together, causing multiple conflicts that shaped our history. Cryptography has shown itself as a tool to make communication between two parties secret to any other partie. This tool has been way more important than we think, and we will explore how it shaped history in the past, in the present and in the future....

The concept of abstraction is fundamentally essential and rooted in human existence. Since 200,000 years, humans have accumulated an immense set of knowledge in many different fields. Doing so has been possible with abstraction, a concept that helps us grow our knowledge in a lot of different ways. We will explore what abstraction is with a philosophy perspective, to help us understand abstraction in computer science and the human brain....

When understood, some concepts can give the learner a completely new perspective of the world. Thermodynamics is one of them. This is a broad and generic subject that gives opportunity to parallel it with a lot of aspects in the world. Today we will parallel it with psychology, and more particularly to the human mind. Thermodynamics is the science of heat, work, temperature and their relations to energy. Let’s decompose these:...
