- How does a computer/calculator compute logarithms? (zachartrand.github.io)
There are many functions on a scientific or graphing calculator that we are introduced to as high school students that, we are told, just work. You select the function, put in the value that you need to calculate, hit “=” or “ENTER”, and SHABAM! You have the correct answer to some arbitrary number of digits that you are ensured are all 100% accurate.
- Mount Persis (summitpost.org)
Mt. Persis is Mt. Index’s little sister. One might say Persis is Index’s stunted twin, for the two peaks share a lot of “facial features.” Both are steep walled on the north and east sides and both are rugged but relenting on their south and west sides. This is understandable, as both peaks are part of a granodiorite intrusion emplaced in the early Tertiary Period (50-60 million years ago).
