By observing tiny ripples in spacetime called "gravitational waves" that propagate away from colliding black holes, ...

Day 3: Light - Reflection Revise the laws of reflection and ray diagrams for plane mirrors. Study spherical mirrors: concave and convex (focal length, uses). Solve ray-diagram problems and ...

Namely, we first optimize the 3D position by using an efficient iteration algorithm based on the alternating optimization and concave-convex procedure methods. Then, the joint design of BF, PA and CPU ...
