Explore the third chapter in a series on special relativity, focusing on Lorentz transformations. Delve into concepts such as boosts, Galilean transformations, Newtonian relativity, and Einstein's groundbreaking insights on the constancy of the speed of light and relative velocity changes between inertial reference frames. Discover the mechanical Minkowski diagram, also known as the mechanical Lorentz transformation or spacetime globe. Learn how these concepts build upon the foundations laid in previous chapters on the challenges of relativity and spacetime diagrams. Gain a deeper understanding of the fundamental principles that revolutionized our view of space and time in just 12 minutes.
