    Most schools in Europe and Asia start their serious physics, chemistry, and biology education around the age of 13. There is a huge gap between the USA system and the rest of the world. Seeing physics pushed to the 12th grade in the USA breaks my heart. Also, there is no standard physics textbook in the USA. One school district on average only has one physics teacher. No wonder even some Princeton undergraduates with decent AP physics scores still struggle in physics courses, and Pre-MED students often complain that Physics is the hardest subject in MCAT. 
   As a professor with 10+ years of physics education experiences and a physics Ph. D. degree from Princeton University, and a mom of two very curious kids who love nature and science, what can I do? 
   By the time when I went to college at the age of 15, I have mastered AP-level physics well. I want to make what I was exposed to at an early age and what helped me to become a real scientist later, available for my kids and their peers.  
   So I created this series of video courses of introductory physics, which are comprehensive and accurate like classic textbooks, as well as interesting and inspiring like an eye-opening mentor. 

All course materials and lectures are in English only.

Ask questions in advance, whenever you want.

Typical Main lecture arrangements

Very often, 4 main lectures (4 weeks) are grouped in a row progressively to provide in-depth of active-learning:

Lecture A (To introduce brand-new topics through inquiry)

  • Question page

  • Recorded experimental demo

  • Questions and discussions based on observations

  • Hands-on experimental assignments.

  • Critical thinking question assignments

Lecture B (To understand related concepts clearly)

  • Question page

  • Draw some qualitative conclusions from previous assignment results.

  • Introduce professional physics terms and explain the concepts using animations

  • More recorded demo/hands-on experiments/critical thinking questions

  • Targeting at a clear understanding of new concepts (differences and connections)

  • Raise more questions regarding cause and effects.

Lecture C (To understand the physics laws--- why and how clearly)

  • Question page

  • Draw quantitative conclusions from previous assignment results. (Physics laws) 

  • More /critical thinking questions//hands-on experiments/ recorded demo 

  • Targeting at a clear understanding of physics laws (cause and effect) (why and how)

  • Raise more questions to apply the new physics laws into daily-life experiences.  

 Lecture D (To focus on applications, problem-solving and more advanced content) 

  • Question page

  • Examples of real-life applications. 

  • Assignments for real-life problem-solving. 

  • More difficult critical thinking questions and some optional hands-on experiments

  • Targeting at a deep understanding of more advanced topics. 

  • Related SAT II physics sample question practice and assignments.
