The Discovery of Radio Waves

When the concept of electromagnetic waves was first proposed around 1864, it was met with great skepticism. As a result, the idea languished for a long time. It took several decades for a handful of dedicated persons — infatuated with the mysteries of electricity and magnetism — to finally put the theory on a solid footing.

In this article, we’ll take a look back at this period that launched the serious study of radio waves. We’ll examine the contribution of James Clerk Maxwell, the man most responsible for the concept. Next, we’ll look at the work of several notable scientists who came after Maxwell, and see how they confirmed the existence of radio waves.

Know Your Basics

To master the art of electronics, it's important for you to learn the basics. I'm talking Ohms Law, serial and parallel discrete components, and simple signal sources. This might seem self-evident, but since the introduction of the increasingly popular microcontrollers and standard sensors and effectors, it's possible to create electronic devices without ever touching a capacitor or resistor.

Electronics Padawans

As the Jedi Padawans demonstrate in Star Wars, acquiring the first 80% of knowledge and skills may take a few weeks or months, but getting a handle on the remaining 20% usually takes years of study and practice under the leadership of a master.

My First Time Machine — Well, at Least My First Flux Capacitor

With a circuit simulator and a basic knowledge of components and circuit theory, it’s possible to simulate just about any electronic device that can be built. Trouble is that circuit simulators and the underlying models are inherently limiting. However, the great thing about simulation is that you can define your own universe in software. So, go ahead, define that flux capacitor.

Easing Into STEM

I’m often asked what the best way is to support STEM (Science, Technology, Engineering, and Math) education with electronics. At the high school level, as soon as I start talking about Arduino boards and sensors, teachers tend to run away. It’s intimidating to set up an electronics workshop from scratch. Think of all the necessary infrastructure that needs to be constructed — from multimeters and soldering irons to parts bins — and the components to fill them.
