What is the significance of logarithm?
Logarithmic functions are important largely because of their relationship to exponential functions. Logarithms can be used to solve exponential equations and to explore the properties of exponential functions.
Who invented logarithms and for what purpose?
The Scottish mathematician John Napier published his discovery of logarithms in 1614. His purpose was to assist in the multiplication of quantities that were then called sines.

How logarithm helped in making our life easier?
The simple answer is that logs make our life easier, because us human beings have difficulty wrapping our heads around very large (or very small) numbers. For example, it’s easier for me to read that my pool water has a pH of 7 (on a logarithmic scale) than a pH of 1 * 10-7 moles.
How are logarithms used in real life?
Much of the power of logarithms is their usefulness in solving exponential equations. Some examples of this include sound (decibel measures), earthquakes (Richter scale), the brightness of stars, and chemistry (pH balance, a measure of acidity and alkalinity).
How did logarithms come about?
Logarithms even describe how humans instinctively think about numbers. Logarithms were invented in the 17th century as a calculation tool by Scottish mathematician John Napier (1550 to 1617), who coined the term from the Greek words for ratio (logos) and number (arithmos).

Who discovered the symbol Infinity ∞?
John Wallis
The common symbol for infinity, ∞, was invented by the English mathematician John Wallis in 1655. Three main types of infinity may be distinguished: the mathematical, the physical, and the metaphysical.
Why did John Napier invent logarithms?
His Latinized name was Ioannes Neper. John Napier is best known as the discoverer of logarithms. He also invented the so-called “Napier’s bones” and made common the use of the decimal point in arithmetic and mathematics….

What was an important contribution of John Napier 1550 1617 )?
John Napier was a Scottish scholar who is best known for his invention of logarithms, but other mathematical contributions include a mnemonic for formulas used in solving spherical triangles and two formulas known as Napier’s analogies.
What are the impacts of the applications of exponential and logarithmic function in the society?
Three of the most common applications of exponential and logarithmic functions have to do with interest earned on an investment, population growth, and carbon dating.
