Seven Brief Lessons on Physics - 5 stars
5 stelle
The first six lessons are concise, accessible explanations of modern physics. If you are reading this you are likely somewhat familiar; I have not seen them explained so lucidly. Those make this worth 4 stars. The last brief is on what it means to be a human consciousness, grasping these concepts, experiencing the world, and perhaps not outlasting the turtle. That last lesson earns this its 5th star.
