I am an engineering student. In my opinion: We learn something. When we do not share what we have learned, we both forget what we have learned and deprive of what we have learned from others. Therefore, as an engineering student, I will try to share with you what I have learned by Allah’s leave. I hope I will succeed on this path. The articles I will share will be about electronics, programming, mathematics, and physics. Because that is my area of interest. Finally, I want to finish my writing with the following words: “Teaching means learning twice.” –J. Joured–
