An oil drilling site in Wyoming. The S.E.C. rule would have required companies to disclose their contributions to climate change and the risks they faced from a warming planet.
A PAC representing wind and solar energy interests spent $1.1 million to boost the Republican primary opponent of Chip Roy, an opponent of renewables. Now they are trying to save a Republican ally in Iowa.

A group of renewable energy investors paid for this projection on the side of the Energy Department building in Washington gloating over Representative Chip Roy’s defeat in a Republican primary for Texas attorney general.
Kinematics: The Velocity-Time Function Author’s Preface: A Collaborative Approach to Lesson Development The intention behind what I hope will be a series of articles on Kinematics (this one being the first) is to begin an open, collaborative process of lesson development on Physics Forums. In order to expedite this workflow, I am making deliberate use...
Introduction This project began life in 2017 when the author had just begun experimentation with GPIO pins on a Raspberry Pi 3. At that point in time a greatly appreciated Christmas present was an “Explorer Hat” module which provided the aspirant programmer with 5 volt tolerant input and output channels (analogue and digital) , capacitive...
In Memoriam In Memory of Dr. Thomas J. LeCompte (1964-2025), Detector Designer and Champion of Education and Science. Prologue Defining “the box” Someone who shows interest in science is initially a welcome development. So are fresh ideas from unexpected quarters. In contrast, there is a scientific community that is meticulously organized down to the last...
Introduction AI and Hybrid Codecs Modern Video codecs are all based on similar principles. Recently, these have been complemented by AI techniques, such as super-resolution, to form hybrid codecs. The current state of the art is one of transition to have one based only on AI eventually: https://deeprender.ai/ Codecs using only AI are several years...
A division by zero is primarily an algebraic question. The reasoning therefore follows the indirect pattern of most algebraic proofs: What if it was allowed? Then we would get a contradiction, and a contradiction is the greatest enemy of mathematical rigor. Many students tried to find a way to divide by zero once in their...
Introduction First, we need some background in Digital Signals. This can be mathematically quite advanced, but since I would like this article to be accessible to as wide an audience as possible, here is a link that explains what is needed (not even Calculus is required): https://brianmcfee.net/dstbook-site/content/intro.html Shannon’s Sampling Theorem An important point not emphasized...
