 Electrons, protons, neutrons, and photons. These are the fundamental building blocks of everything you see around us, from the tiniest grains of sand to the biggest stars in our cosmos. But they defy Newton's laws. So to understand them, we need to introduce a new set of principles called quantum mechanics, which we will learn in this course, modern physics. But why study them, you ask? Because the technology that shapes our very lives is based on these rules, from semiconductors that allow you to store gigabytes of information in your pocket to fusion reactors that could one day provide us with limitless energy. This modern physics course will unlock the secrets behind these all. Are you excited? Let's dive in. This course covers the main topics of class 12 CBC, modern physics sections. But the units are centered on big themes. Like can we consider atoms to be like tiny solar systems? Or how do we determine the age of the fossils? This ensures that everything that you learn inside is used to answer relevant questions of nature. So you don't feel like you're just learning some abstract things only for your exams. And speaking of exams, to give you complete mastery, inside every unit you'll find videos, practice questions, exercises, and practice questions. Quizzes and unit tests. So together let's explore the wonders of these modern physics and I get a glimpse of how our technology works. I'll see you inside.
