How Do Binoculars Work

Binoculars work like a pair of matching telescopes, except they provide a magnified stereoscopic view of faraway objects. Their main advantages over a single lens monocular (telescope) is that they provide depth perception, they’re more comfortable as they allow viewing with both eyes and the visual acuity is better because the brain has two sets of visual data to process.

How Does A Gaming Joystick Work

Joysticks essentially translate the movement of your hand into a digital format that a piece of software can then interpret to perform an action.

They’re used in a number of ways, from flying supersonic aircraft to controlling wheelchairs – to name just two – however joysticks are probably most commonly encountered as a major element of people’s gaming systems. […]

How To Curl Hair With Flat Straighteners

When human hair lacks enough natural moisture, or when it’s exposed to high or low humidity, it may become brittle and/or rough. To this end, hair straighteners, or flat irons, can be used as a quick and easy way to make frizzy and curly hair temporarily straight. […]

How Does Atomic Force Microscopy Work

Atomic force microscopy (AFM) is a branch of scanning probe microscopy that includes several dozen ways of scanning the surface of a tiny specimen to create an image. It can resolve images of objects mere nanometers long, over 1,000 times sharper than the best optical microscopes. […]

How Smart Glass Works

Smart glass is a general nickname for glass that is electrically switchable between tints or shades. There are several different types of smart glass technology, however the most prolific are suspended particle devices (SPDs). […]

How Do 5.1 Headphones Work

There are two types of 5.1 surround-sound headphones: simulated and non-simulated.

Non-simulated, or ‘true’, 5.1 headphones use multiple speakers embedded in the headphones’ two earpieces to generate multi-angle sound placement, while simulated varieties employ complex sound-processing algorithms to create the same effect.

How Do Ejection Seats Work

Ejection seats are a type of in-cockpit motorized chair that, in an emergency situation, can rapidly propel themselves – along with their occupant – out of an aircraft.

The propulsion force is delivered by either the detonation of an explosive charge located under the seat or by rocket motor, with the ejection out of the cockpit occurring in two key stages. […]

Top 5 Biggest Massive Mining Machines

The world is still primarily reliant on fossil fuels for energy generation.

With billions of people across the globe, this means the demands that are placed on the mining industry are huge. Extracting these fossil fuels as efficiently as humanly possible is of utmost importance, and for best efficiency and ability to meet this demand, you need scale. And the five machines featured across the next six paragraphs definitely fit the bill scale. […]
