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 ...

Dr. James McCaffrey from Microsoft Research presents a complete end-to-end demonstration of computing a matrix inverse using ...

ABSTRACT: “All is Number”—the universe follows a few profound mathematical rules, and pure thought can grasp reality. This paper explores the first principles of fundamental physics, focusing on the ...

Abstract: We propose a systematic and efficient extension of the multimodal transfer-matrix method to obtain the dispersion diagram of structures with 2-D periodicity specifically targeted to ...

Rebooting the ESP32 didn't help. I changed the number of LEDs several times, but could never address more than 60 LEDs, until I switched back to 2D Matrix and set the matrix to 1 x 1, and from there I ...
