Aluminum is a key component in many items we take for granted today, including aircraft, electronics, kitchenware, and buildings. Although aluminum is a now a common material, it was not always so easily

Short video of NASA's Dual Asteroid Redirection Test mission being launched by SpaceX from Vandenberg SFB, California. Quality is so-so, not the best I've taken of a night launch. During this launch there

Introduction Many communication and storage technologies rely on data compression to increase throughput or apparent storage capacity. Data compression is a way to reduce the size of data by taking advantage

In last week's physics post we covered basic kinematics in one dimension. This post covers in detail how to solve each of those problems. Problem 1 a. What is the velocity of a satellite that travels 75km

Covers the differences between Adam & Eve's creation and sin

While browsing some site a few days ago I came across the question, "Why don't people trust science any more?" As I suspected upon first seeing the question, the person who posed it went on to

Initial framework for cryptocurrency acceptance by local governments

Introduction This is the first in a series of posts covering physics. Why bother create a bunch of posts covering what many people here probably already know? The main reason for me to do this is because

Overview One of my current projects is a book covering DIY computer system design for readers who have little knowledge of electronics. There are plenty of books and online how-tos out there instructing

Cheap, reliable energy has made the modern world possible. Where once humans and animals burnt calories to provide the raw power to perform work, machines now burn fuels or consume electricity in their

The Space Force's space surveillance network is a collection of systems used to identify and track ICBMs as well as satellites, spacecraft, space debris, and other objects near Earth. Various agencies

In this video we take a look at something power plants monitor in order to figure out if they need to produce more, or less, electrical power. By monitoring the frequency of the alternating current, power

In the third video on capacitors we discuss how plate area and plate distance affect capacitance, as well as what dielectrics are and how they can be used to optimize capacitors. If you enjoyed this video,

Others have talked about the various threats to your privacy (and sometimes security) that today's world of wireless devices poses. Let's take more of a technical look at how wireless devices can threaten

Railguns have long been popular elements in sci-fi and games. In this video we take a brief look at the very basics of how railguns work. If you enjoyed this video, you can find me on Odysee as well as

Magnetic fields are an integral aspect of all electrical and electronic systems. In some cases magnetic fields and their effects are unwanted, and in other cases they are central to the operation of a

A supplement to the phased array video I previously posted. This covers why, for example, a boresight angle of 45 degrees may require a phase shift other than 45 degrees.

We often see it takes hours, days, and in some cases weeks to create a suitable vacuum in a system used for experiments or in industry. In this video we take a look at why it takes so long. An example

Phased arrays are antenna systems composed of numerous smaller radiating elements positioned in a linear or grid arrangement. They are often used in military, air traffic, and weather radars. This video

The Defense Support Program (DSP) has provided ballistic missile early warning for decades. This video takes a brief look at how DSP satellites work. If you enjoyed this video, you can find me on Odysee
