Quantum physics is a branch of science that studies how matter and energy behave at the smallest scales like atoms and subatomic particles. Unlike classical physics, which explains everyday objects like cars and planets, quantum physics deals with strange and often unintuitive behaviors. For example, particles can exist in more than one state at a time (called superposition), and they can be "entangled," meaning the state of one particle instantly affects another, no matter how far apart they are.
Why Quantum Physics Matters
Though it may sound abstract, quantum physics plays a big role in our everyday lives. Technologies like lasers, MRI machines, and even smartphones rely on principles of quantum mechanics. It also forms the foundation of cutting-edge fields like quantum computing and quantum cryptography, which promise to revolutionize how we process and protect information. In short, understanding quantum physics helps us grasp the invisible forces shaping our modern world. Shutdown123
