The History of Logarithms Mid-Unit Assignment 2
The Engineer:
As an engineer, you will focus on finding information about how
logarithms were used to solve problems at the time it was invented.
Also, consider how similar problems were solved before logarithms
were created. Consider:
 What tools were needed to complete calculations before the
invention of logarithms?
 What tools were used, or needed, after logarithms were created?
 How do we use logarithms today that differs from the way they
were used when they were invented?
 How do you use the tools of logarithms to solve problems?
All types of engineers use natural and common logarithms. Chemical engineers
use them to he parton model and quantum chromodynamics for example L. B.
OKUN (1984) argued that “scaling is not absolute even for Q2 → ∞, ν → ∞,
and Fi(x) must be a logarithmic function of Q2” (para. 1), and pH solutions, which
are measured on a logarithmic scale. Exponential equations and logarithms are
used to measure earthquakes and to predict how fast your bank account might
grow. Shaffer and Johnston (2013) explain that “Biomedical engineers use them to
measure cell decay and growth, and also to measure light intensity for bone
mineral density measurements.” (para 2)
