I want to learn quantum physics in an easy way

Quantum Physics Made Easy: A Beginner’s Guide

1. Why Quantum Physics?  
   - Studies nature at atomic and sub-atomic scales.  
   - Reveals phenomena like wave–particle duality, uncertainty, superposition and entanglement.

2. Key Concepts (Intuitively)  
   • Wave–Particle Duality: Particles (e.g. electrons) sometimes behave like waves (diffraction).  
   • Heisenberg’s Uncertainty Principle: You cannot know both position and momentum of a particle exactly.  
   • Superposition: A quantum system can exist in multiple states until measured.  
   • Entanglement: Two particles share a linked state, even when far apart.

3. Prerequisites  
   – Basic algebra, trigonometry, complex numbers  
   – Introductory classical physics (Newtonian mechanics, basic waves)  

4. Learning Path  
   a. Conceptual Overviews  
      • “Quantum Mechanics: The Theoretical Minimum” by Leonard Susskind & George Hrabovsky  
      • MIT OpenCourseWare – “8.04 Quantum Physics I” (video lectures)  
   b. Visual & Interactive Tools  
      • PhET Simulations (University of Colorado)  
      • Veritasium, MinutePhysics, PBS Space Time (YouTube)  
   c. Introductory Texts  
      • “Introducing Quantum Theory” by J. Polkinghorne, P. Filk & C. Müller  
      • Feynman Lectures on Physics Vol. 3 (chaptered for beginners)  

5. Study Tips  
   1. Start with thought experiments (double-slit, Schrödinger’s cat).  
   2. Focus on physical intuition before diving into math.  
   3. Work through simple problems to see principles in action.  
   4. Discuss ideas—join online forums or study groups.  

6. Further Steps  
   – Advance to formal courses in linear algebra and differential equations.  
   – Explore lab demonstrations or quantum programming (e.g. IBM Quantum Experience).
