Write a brief autobiography of ‘a mask.
Answers
Answer:
A cloth face mask is a mask made of common textiles, usually cotton, worn over the mouth and nose. When more effective masks are not available, and when physical distancing is impossible, cloth face masks are recommended by public health agencies for disease "source control" in epidemic situations to protect others from virus laden droplets in infected mask wearers' breath, coughs, and sneezes. Because they are less effective than N95 masks, surgical masks, or physical distancing in protecting the wearer against viruses, they are not considered to be personal protective equipment by public health agencies. They are used by the general public in household and community settings as perceived protection against both infectious diseases and particulate air pollution.
The design of the mask took a big step forward in the 19th century. In 1827, Scottish scientist Robert Brown discovered "Brownian motion," which theoretically proved the protective effect of masks on dust.
In 1848, the mask made by American Lewis Hassley for miners obtained the first patent for a protective mask, which was a milestone in the history of face masks. Masks at this stage were closer to gas masks. Hassley applied for the patent in 1849 with the patent number 6529, which is still available in the archives in the US.
In 1861, French biologist, microbiologist and chemist Louis Pasteur proved the presence of bacteria in the air, which made more people pay attention to the design of modern masks.
Answer:
Explanation:
A mask is an object normally worn on the face, typically for protection, disguise, performance, or entertainment. Masks have been used since antiquity for both ceremonial and practical purposes, as well as in the performing arts and for entertainment. They are usually worn on the face, although they may also be positioned for effect elsewhere on the wearer's body.
More generally in art history, especially sculpture, "mask" is the term for a face without a body that is not modelled in the round (which would make it a "head"), but for example appears in low relief.
