Two words in the diagram explained:
logarithm (connotation outside math, baroque)
How does one find the log of a number? The logarithm of a number is the power to which 10 must be raised to equal that number. Some examples are
- 10 squared = 100, therefore log10 of 100 = 2
- 10 cubed = 1000, therefore log10 of 1000 = 3
aqueous (connotation outside science, baroque)
Aqueous is an adjective meaning “of or containing water.”
