Video games are roughly described as an electronic game with some rudimentary form of interaction in terms of the player having control of some aspect of the game, and there being a point to playing. Video games weren’t invented until after the invention of the computer since a […]

Opera is a form of stage musical, quite different from typical Broadway musicals, and is often considered more cultural because it incorporates classical music and period costumes. Despite the use of classical orchestras, and a distinctive style of singing, opera actually describes a type of stage drama where singing is the main method of delivering lines instead of the more usual method of speaking a part. The renaissance era in Europe, especially in Italy, was […]

Radio refers to both the technology used to broadcast programs, and also the underlying science of radio waves, which are actually electromagnetic radiation that travels in waves just like light. Radio, even though it is used to broadcast audio signals is not in fact sound, though sound also travels in waves, but much much slower than radio waves. Because radio is electro magnetic, it’s discovery goes back to around the same time that electricity was […]

Unlike the telephone, computer, or television, electricity wasn’t really invented since it is a naturally occurring phenomenon that is easily seen whenever lightning rods are present during a powerful storm. Electrical storms can release more electricity in a single storm than the entire world uses in a year, most of the time storms and lightning is quite safe, but whenever electricity is present, the natural attraction of the current is to the ground, and anything […]

As […]

Since the invention of the wheel people have been using carriages drawn by horses and donkeys for transport, but the invention of the car truly redefined transport since speed was no longer limited by the speed of the slowest running horse. Desire for a horseless carriage has been around for many hundreds of years, and some of the first experiments predate the industrial revolution. Cars, which are also known as automobiles have gone thru many […]

Cellphones, also called mobile phones, are an invention that in the late 1990s and into the 2nd millennium have become so ubiquitous many people can’t imagine life without them anymore. Cell phones work wirelessly using radio waves to communicate with a tower that transfers the call to the network, and then to the phone of the other party. The idea of using towers arranged in a cellular pattern with each only handling a small area […]

Paper clips are such a simple invention most people would be forgiven for thinking they must have been invented thousands of years ago, perhaps by ancient ancestors who first learned to work with tin or iron. Steel is notoriously difficult to work with, and especially so when small items like wire for a paper clip are being produced. In fact paper clips couldn’t have been invented earlier than 1830, the year an American doctor named […]
