Do you know logarithms? In school, we learn that logarithms are "x when x=log(a)b" or "the reciprocal of an exponential function," but this doesn't really explain what they are for. Logarithms are actually used in many data in our daily lives. For example, units of earthquakes, decibels to express volume, and many others. When they are used, they are used when "numbers are huge and difficult to handle" or "when the range of numbers is too wide and difficult to handle." In such cases, logarithms are useful because they compress large values. It is also said that human sensations can be unraveled with logarithms. The weight, temperature, and spiciness you feel when holding something... The degree of such sensations can be quantified with logarithms...! In this article, let's take a look at how logarithms are used in our daily lives! ★Contact us at [email protected] #mathematics#logarithms
