To find out the meaning of the word “dummy”, take a look at the dictionary. For what areas are dummies necessary? We find the following definition: dummy is a model that completely repeats the original, its shape, color, structure, but does not fulfill its functions. Thus, if there is no original, in some cases it can be successfully replaced with an identical model.
For example, camera models provide security. Installing a full-fledged video surveillance system is an expensive procedure, and a fake can well serve to ensure security at the household level.
Models in art
Artists most often use copies of objects. These are models of vegetables and fruits, stuffed animals and birds. Drawing a still life of fresh fruits, the painter is very limited in time - the products can deteriorate, change color. When large-scale work is written, time becomes a whole problem. The dummy will successfully fix it.
Wax or polystyrene fruits do not have an expiration date and can pose as much as needed. Similarly, with plaster casts of the famous statues of Apollo, Venus of Milos - the original in the world is only one, and there are as many copies as you want.
In cinema and animation, dummies play a huge role. The famous film "Titanic" would never have been released, if not for a copy of the ship. This dummy drowned during the filming, and the crew had the opportunity to correct certain frames. It’s even scary to imagine that it would be possible if every new film flooded a whole ship.
In the animation, superheroes save the world by jumping on the roofs and running along sheer walls. If an animated film is being shot, then the foam characters of the main characters are released onto the walls, and the entire scene is collected in special programs on a computer.
Models in science
It is difficult to imagine the training of future doctors without the use of dummies. Often you need to show, try and step by step to disassemble this or that procedure. Of course, future doctors use not only plastic models. Nevertheless, dummies are an indispensable part of practical exercises.
In mechanical engineering, human models equipped with special sensors are used to test vehicle security systems. Crash tests of the transport model are carried out, and the need for corrections is judged by damage to the dummy.
The use of dummies in human life is limited only by his imagination. The more realistic they are, the more reliable and more accurately the actions carried out with them.
