Hey everyone! I am on a quest to understand the world in which we live in better. In doing so I'm making a stop at Physics. I was suggested the book "A Theoretical Minimum - What you Need to Know to Start Physics". I am in love with this book and cannot put it down. At the moment I am reading about vectors. Before I move on I want to make DAMN sure I understand what is being said, technically and conceptually. Now, I have taken a college level physics course but got lost along the way and ended up dropping. After reading this book I understand so much more where certain things come from; I understand these are concepts/discoveries that are built from those who have come before us. Anywho, Keeping the subject matter of this particular book in mind, Are there any kind of interactive programs/visuals that would help in understanding of topics such as: vectors, vector addition/multiplication, trigonometry( understanding sin, cos, tan better), etc... I'm looking to understand this visually as well as paper calculations and numbers. I thank you for taking the time to read!
