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 technique is described for obtaining approximate solutions to the wave equation when a dielectric variation exists in the direction of propagation. The method consists of approximating the ...
Differential equations are fundamental tools in physics: they are used to describe phenomena ranging from fluid dynamics to general relativity. But when these equations become stiff (i.e. they involve ...
In January I wrote a piece titled “ 5 Physics Equations Everyone Should Know .” Lots of you weighed in with your own ...
Since that day, LIGO — composed of two highly sensitive laser interferometers located in Hanford, Washington and Livingston, ...
Math equations used to be a daily chore for many elementary schoolers. But entering adulthood means those less mathematically inclined often never have to think about them ever again. And it appears ...

Math equation mystifies people as they forget 'special rule' - can you solve it in 30 seconds?
A back-to-basics brain teaser is dividing the internet. BholanathDutta shared the sum 100 + 100 × 4 = ? on X, formerly Twitter, sparking debate among users. At first glance, many people speed to the ...
Abstract: To address the stability constraints associated with small elements in the traditional explicit wave equation-based discontinuous Galerkin time domain (DGTD) method for multiscale modeling, ...
In 2020, Jenna Marbles — one of the most popular YouTube creators of all time —posted her last video. Five years later, her devoted fanbase still wonders: where is she, ...
