An X-ray machine, usually referred to as an X-ray generator, is a device used to take images of the inside of an object. They are best known for their use in the medical field where they can help medical professionals see inside the body to make a diagnosis (such as looking for a broken bone or tumor). However, they are also important for tool used in security such as with x-ray luggage scanners at airports. Basically, X-ray machines work by passing a beam of X-rays (a type of electromagnetic radiation) through an object. Some of these beams pass through and some are absorbed. The differing pattern of radiation is detected by a special detector screen or device to produce the final image. The X-ray machine was one of the most important medical advancements of all time. Let’s find out who invented this device.
The revolving door is a specially designed building entrance that features a central shaft with three to four doors (also called wings) attached. These doors, usually made of glass so that people can see each other, revolve in a circular pattern to allow people to enter and exit the building. These doors are popular with large building because they are sealed to the weather. This means that they prevent drafts and reduce the cooling or heating requirements for a building. They are also sometimes used in high security settings to allow only one person to enter/exit at a time. Let’s find out who invented this unique type of door.
The Etch A Sketch is a children’s drawing toy that has remained popular since its introduction. The basic Etch A Sketch features a gray screen and red frame with a knob on each side of the bottom of the toy. These knobs can be twisted to create lines on the screen. The left knob creates horizontal lines and the right creates vertical lines. The inside surface of the screen is coated with aluminium powder and a stylus scrapes the powder away as the knobs are turned to create the lines. This is a relatively simple device, but has been rated as one of the best toys of all time. It was inducted into the National Toy Hall of Fame in 1998. Today, the Etch A Sketch is owned by the Ohio Art Company. Let’s find out who invented this popular toy.
The safety pin is a pin which also includes a clasp and spring. The clasp protects the person using the pin from being pricked by the sharp pin and it also closes the pin to provide a strong fastening. These pins were traditionally used for cloth baby diapers (nappies) because the baby is protected from the pin, but are also used for fastening fabrics/clothing or attaching accessories to clothing. The earliest similar invention was the fibula, an ancient type of brooch that dates back thousands of years, but this invention was eventually forgotten. Compared to the fibula, the modern safety pin is a very recent invention. Let’s take a look at the story behind the safety pin.
The snowmobile is a powered vehicle specifically designed for traveling on snow or ice. They are similar to an all-terrain vehicle (ATV) and can be used in any area covered with snow or ice. In most cases they are ridden solo or with a single passenger. Like a motorbike or ATV, they are unenclosed and the rider is open to the elements. Snowmobiles are propelled by an engine that drives a continuous track(s), with skis at the front of the vehicle to provide control. They were originally developed because transport during the winter season was difficult. They are still very important for this task, but are also popular for recreational purposes and racing. Let’s find out who invented this important winter vehicle.

Most gummi bears are made out of sugar, glucose syrup, colors and flavors, starch, citric acid and gelatin, although other ingredients may be used in certain cases. These ingredients are mixed and heated, and this mixture is then poured into molds and allowed to cool. Let’s find out who invented these popular treats.

They have been one of the most popular brands of hard candy for many years and 2012 marks 100 years since they were invented.
Auto-Tune is a hardware and software pitch correction system designed to correct off-key singing or instrumental music recordings to produce perfectly tuned vocals and/or music. It can also be used to distort the voice/music to create a unique “robotic” effect.

Today, the producers of many top artists use Auto-Tune to create pitch perfect songs. However, the use of the software is the subject of much debate in the industry. Let’s find out who invented this controversial audio processor.
