Every year on February 4th, Create a Vacuum Day is celebrated mostly in the United States. When we refer to the term ‘Vacuum’, we, the general mass mean the vacuum cleaner indeed. The word vacuum originated from Latin word which means ‘Empty’. The real vacuum space can be referring to space where the gaseous pressure is much more less than the atmospheric pressure.
First laboratory vacuum was produced by Evangelista Torricelli in 1643. Till then vacuum is in great use. In 20th century vacuum was widely used in varied technology purposes. The then computers were made using the technology of vacuum. But the only drawbacks were that it would take much more space. So it is replaced by modern technology. But still vacuum is in talk by means of space-technology.
