Word origin
The term 'IR' can refer to various concepts depending on the context, but its origins can be traced back to the development of electromagnetic theory in the 19th century. The term 'infrared' was coined in 1800 by the British scientist Sir William Herschel, who discovered infrared radiation while experimenting with sunlight and temperature measurements. The abbreviation 'IR' became common in the 20th century as technology advanced, particularly in the fields of telecommunications and imaging. In finance, 'interest rate' has its roots in banking and economic theory, evolving over centuries as formal systems of lending and borrowing took shape, becoming a crucial concept in modern economies.
