Transistors
A transistor is an electronic component whose function is to act as a switch as well as an amplifier. Automatic computations are done through the use of billions of nanoscopic transistors that are contained in computers, phones…etc.

Quantum Computers – Algorithms
Introduction This article is Part 3 of a series on quantum computing. In Part 1, we covered an overview of the history, principles, types, and quantum computing applications. In Part 2, we explored its computational mechanism, including quantum mechanics experiments and principles, quantum gates, mathematical representations of qubits, and quantum measurement. We also dived into …
Noise cancellation
We all listen to music or watch videos using headphones every day. We all commute to school using trains and buses. However, unwanted noise generated by these vehicles can reduce the quality of our listening experience. So, companies, such as Bose, came up with the technology called noise cancellation. This technology enables us to listen to the sound more clearly as if we are listening in a quiet place. Some of you might have AirPods, Bose headphones, Beats headphones, etc. These headphones are famous for their noise cancellation technology. In this article, I will explain how this technology works.
Neuralink
Neuralink is a company that was created in an effort to “merge computers with human brains. They are developing a device—same name as the company—that will first be used to help paraplegics with simple tasks such as using an iPhone and making mouse clicks on a computer—by making no physical movement. It is essentially a chip connected to wires which fan out into the human brain, capable of both recording brain activity and stimulating it.

Does Free Will Exist?
Introduction We make a lot of decisions in our life–from what to get for dinner to which career to pursue. Even the smallest of the decisions (like choosing to do a quick stretch) is what consists of our everyday life. We often believe that we are in control of our own actions, and as a …
Miniature Robots (Part 1)
Introduction Within the last decade, it has become possible to design and create sub-gram miniature robots. The demand of miniature robots comes from the potential for their applications, ranging from artificial pollination to complex surgeries and search and surveillance missions. Miniature robots can have the potential to complete or assist tasks that are difficult for …
Introduction to Aerodynamics
Air travel is one of humanity’s greatest inventions but how exactly are such giant balls of metal able to fly? The answer is based on a branch of physics called aerodynamics. Aerodynamics is defined as the study of the interaction between an object (usually a solid) and air. There are 4 main forces of aerodynamics that allow planes to fly:
Introduction to Superconductivity
In a superconductor, due to the absence of resistance, once current is generated, it will continue to flow eternally even without a power supply (e.g. battery). Superconductors are used in Maglev trains, MRI scanners, particle accelerators…etc.
Semiconductors and LEDs
Semiconductors are made up of a crystalline material. The most commonly used element in semiconductors is silicon. Silicon has a crystalline structure at room temperature and its atoms are arranged in a way that makes it very stable at room temperature.
