Qais Lectures on Physics
May 24th, 2024
Physics (from Ancient Greek: physikḗ, which means 'knowledge of nature'), is the natural science that studies the structure of matter, the interactions between the fundamental constituents of the observable universe, its motion and behavior through space and time, and the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, and its main goal is to understand how the universe behaves. It is scope of study encompasses not only the behaviour of objects under the action of given forces but also the nature and origin of gravitational, electromagnetic, and nuclear force fields. Its ultimate objective is the formulation of a few comprehensive principles that bring together and explain all such disparate phenomena.
If you want to become a successful physicist, you have come to the right place … This page was prepared for young physicists thrilled by the challenges posed by studying physics.
First, you should know that the English is a prerequisite. You should learn it to be able to read, write, speak and understand English. All textbooks and publications are in English. If you want to be a researcher and publish your results, you should know that all publications are in English.
To be a successful physicist, you must have the knowledge, skills and understanding these main and important topics:
First, you should be proficient in mathematics to be a successful physicist. You should be good at mathematical concepts and how to apply them. In these lectures, I will mention the main mathematical topics we need to study in physics. Math is considered the language of physics, so if you dislike mathematics, you may want to pursue other educational options.
Before you begin studying physics and working through the topics, courses, as well as research, you need to be familiar with Mathematics.
These lectures are hand-writing. The final draft of classical mechanics will complete Soon !

To the best of our knowledge, the universe is governed by four forces. Gravity is the dominant force at the largest scales. The two nuclear forces hold away at the very smallest distances. The electromagnetism applies to everything in between. Electromagnetism controls the interactions between atoms and molecules at the atomic level. Remarkably, four straightforward and sophisticated equations encompass the entire explanation of the force of electromagnetic. The Maxwell equations are the name given to this. Few areas in physics, or any other field for that matter, can explain how such a highly varied collection of occurrences can arise from so little. This course aims to present the Maxwell equations and explore some of the several narratives they hold.
The goal of these lectures is to help you start to comprehend the quantum world and some of its strange behaviors. This is a bit of a step into the unknown, as should already be evident, and our classical intuition will not serve us well in the quantum world. Luckily for us, the language of mathematics describes the quantum world remarkably well for reasons that we still do not fully comprehend. Throughout these lectures, we will adopt an approach that embraces this mathematical description and uses it to develop a fresh sense of how the universe actually functions.
PART VI: Statistical Mechanics & Thermodynamics
