Rotation matrices for x, y, and z axes are detailed, including a z-axis rotation matrix using cosθ and sinθ. Euler angles describe orientation, supporting forward and inverse kinematics. Key problems ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

A new study published in Nature Astronomy, led by Dr. Jie Yu, from the Australian National University, reveals that stars in ...

This pioneering book presents a study of the interrelationships among operator calculus, graph theory, and quantum probability in a unified manner, with significant emphasis on symbolic computations ...
