The idea of return can be associated with a comeback or a setback .
Return is the process and result of returning (going back, going back, returning). For example : «The singer's return to the country is scheduled for tomorrow at four in the afternoon» , «Please note that the products on sale cannot be returned» , «A protest on the highway caused complications in the return after the long weekend» .
In certain contexts, return is a payment , a reward or a profit that is obtained. We speak of return on investment to refer to the benefit received from a certain amount invested. This concept, which is also known as ROI , allows us to know the performance of an investment .
Return as a bribe
In Argentina , the term "return" is often used to refer to bribery or kickbacks . In this sense, return implies a gift that constitutes the crime of bribery .
An official may assign the execution of a public project to a certain company in exchange for receiving a return. This company, therefore, invests two million pesos in the project and gives a gift of two hundred thousand pesos to the official.
In Argentina, it is referred to as a return to bribery or kickbacks.
The term in various fields
The idea of return also appears in technology ( future technological return ), in engineering ( return period ), in telecommunications ( return channel ) and in philosophy ( eternal return ), among other fields.
Future technological return is understood, for example, as an argument used to support the need to invest large amounts of money in basic scientific programs (those carried out without short-term objectives, but with the aim of obtaining more knowledge about reality or the foundations of nature) whose chances of success are not promising at first glance, or which require a long period of work to see results.
The return period
The idea of return period appears in various areas of engineering to refer to the time expected to elapse between two low probability events .
In hydraulic engineering, a common example is the average time between two floods of equal flow, or greater than a previously defined flow. In seismic engineering, on the other hand, it can be understood by observing the average time between two earthquakes whose magnitudes exceed a certain value .
The return period is also called recurrence period and is a statistical concept used to evaluate an event taking into account its level of rarity .
The concept in telecommunications
Thanks to the return channel, it is possible to communicate between the provider of an interactive service and its receivers, since the latter's responses are sent to the servers of the former. This is very common in Digital Terrestrial Television (known by its acronym DTT ), since it gives users the possibility of sending direct responses to the provider.
For the exchange to be effective in this area, it is necessary to have an Internet connection at both ends. The most common types of return channel are the telephone line , Ethernet , Bluetooth and WiFi .
The eternal return
Philosophy defines eternal return as a repetition of the world that consists of becoming extinct in order to be born again.
According to this conception, the world returns to its origins through conflagration , that is, it burns down completely. When nothing remains but its ashes, the world is rebuilt to give rise to the same succession of events as in its last period of existence.
