In this Python astrophysics tutorial, I walk you through calculating the gravitational field produced by a ring of mass. Using numerical methods and Python libraries, we explore how to compute ...

Whether you’re solving geometry problems, handling scientific computations, or processing data arrays, calculating square roots in Python is a fundamental task. Python offers multiple approaches for ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Abstract: A novel 3-D nonuniform Fourier transformation (3-D-NUFFT) method is proposed for the efficient calculation of the array factors of conformal arrays. Interpolation in a least-squares sense is ...

Not only is the latter easier to read, it's hundreds of times faster than the for loop (and provides opportunities for hidden vectorization and parallelization). However, the Numpy abstraction stops ...

Python is convenient and flexible, yet notably slower than other languages for raw computational speed. The Python ecosystem has compensated with tools that make crunching numbers at scale in Python ...

# Welcome to Course 4's first assignment! In this assignment, you will implement convolutional (CONV) and pooling (POOL) layers in numpy, including both forward propagation and (optionally) backward ...
