I have a BS and MS degree in Geology. During my studies I was required to take an abundance of math and math-intensive class including algebra, trigonometry, calculus, chemistry, physics, and geophysics. I have often used basic algebra in my position as a geologist and even in projects at home (e.g., cooking).
I have a BS and MS in Geology, am a professionally registered geologist in AZ, and have taught both Geology 101 and 103. Additionally, I have worked in several different geologic fields including environmental, mining, geotechnical forensics.
I have been using MS Excel for close to twenty years, primarily for geologic endeavors. I've used it to find the change in density with depth as you go deeper into the Earth as well as estimating the net present value of a potential sand and gravel pit.
I've been using Microsoft Word since the early 1990's. I've completed numerous homework assignments, research papers, and scientific/environmental reports via MS Word. I've had specific training on some of the earlier versions, but most of my learning has come from experience.
Although my degrees are in geology, I've done quite a bit of scientific writing associated with those studies. I wrote a 100 page Masters thesis and numerous geological evaluations and technical reports during my years in the consulting field. I'm also an accomplished screenwriter, a hobby I've been enjoying for over ten years.
