    High School Feynman's lectures: Newton’s Laws of Dynamics

    Thank you very much! I agree that Feynman explains it well, but I still have gaps in my knowledge.

    Undergrad Feynman lectures on physics: random walk

    I do not understand the formulas (6.11) and (6.12) in volume 1 of the Feynman lectures on physics, the entire paragraph between equations (6.10) and (6.12) is generally not very clear. Please explain (preferably in simple language, I'm 13). Thanks!
