In Python Physics Lesson 20, learn how to calculate a rod’s moment of inertia using Python! This tutorial breaks down the physics concepts, formulas, and step-by-step Python coding techniques to ...

Abstract: Reducing the number of antenna elements within a fixed aperture while maintaining low sidelobe levels is a key challenge in sparse array design. Although various sidelobe suppression ...

Abstract: In this article, a circularly polarized antenna array using sequential rotation feeding technology is designed. The radiation unit of the antenna is based on cutting off two diagonal square ...

An array is not useful in places where we have operations like insert in the middle, delete from the middle, and search in unsorted data. If you only search occasionally: Linear search in an array or ...

This project implements a systematic trading strategy that rotates monthly between the S&P 500 ETF (SPY) and the Nasdaq-100 ETF (QQQ) based on their trailing 3-month performance. The goal is to ...

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 ...

In June 2025, photographs accurately reported Norway had developed and installed underwater turbines for energy production that were friendly to marine life. The meme in circulation falsely claimed ...

A young computer scientist and two colleagues show that searches within data structures called hash tables can be much faster than previously deemed possible. Sometime in the fall of 2021, Andrew ...

You are given an n x n 2D matrix representing an image, rotate the image by 90 degrees (clockwise). You have to rotate the image in-place, which means you have to modify the input 2D matrix directly.
