Applied Physics

Inventor and AC electricity proponent Nikola Tesla was on a mission to transmit energy through thin air almost a century ago, but, claims about a conspiracy to keep his work quiet aside, experimental…

In the comments section of my previous article I demonstrated an optical Theremin. This article is the build for that circuit. The circuit and circuits that are similar to it in function have also…

littleBits are color coded electronic modules that connect together magnetically to create simple electronic circuits. They are designed for ages 8 and up so hobbyists, designers, makers, and artists…

A way to microscopically view battery electrodes while they are bathed in wet electrolytes means it is possible to mimic the realistic conditions inside actual batteries. It may not seem possible…

Physics can give pointers for energy saving and an can provide materials scientists with tips for the development of high-temperature superconductors.  Nearly two percent of the electrical…

As I mentioned in my review of the Chem C3000, it’s sad that science kits usually can’t compete with more mainstream stuff like Guitar Hero. They also tend to be pricey, but the upside is that online…

Arc discharges are common in welding and lightning storms but what about about in altered gravity conditions? How often does that really come up? Not often, unless we ever send manned missions into…

The word 'synchronization' is part of our cultural lexicon - we 'sync up' with other people, 'sync our computers' and 'get in sync'.    There's a reason it resonates (we'll come back to our…

In a previous article I demonstrated how to build a conductivity tester out of Snap Circuits for your Science Play and Research kit. You can use the same circuit with a small modification to build…

Many owl species have developed specialized plumage to effectively eliminate the aerodynamic noise from their wings, allowing them to hunt and capture their prey in silence.  And owls are…
