I use algebra almost everyday in my masters program, solving for variables for fluid velocity, pressure, temperature, etc. I also use it in more common place applications, such as when I built my wood shed and had to determine how many of each type wood I needed to buy.
My oldest son has Aspergers. My wife and I were extremely involved in his education and performance at school. He went from not being able to eat in the cafeteria in kindergarten to being a straight A honors student. He just started his Freshman year at Boston University and is double majoring in Computer Science and Linguistics (how ironic).
Aspeger's Syndrome (AS) children need a lot of structure in their life and they usually obsess on a given topic, which may change as time goes by. They have difficulty focusing in distracting environments and do not learn the same way as other children. As a result, they do not pick up on the social cues that non AS children do and have extreme difficulty interacting socially with peers and adults.
I use calculus almost daily when I am working on my masters program in fluid dynamics. Many fluid properties depend on rates of change or integrals of other properties. For example, conservation of mass of a fluid is related to the change in velocity (which is a derivative).
Differential Equations is another fundamental course required for mechanical engineers. Ordinary and partial differential equations are an everyday part of my Masters classes. I have used DifEq's to solve complex fluid flow and heat transfer problems or convert non-linear equations to linear equations so that they are easier to solve.
As a submarine officer, I use geometry to assist me to surface contacts when looking out of the periscope. Knowledge of geometry allows my to calculate a surface ship's course just by knowing what bearing the contact is on and observing his "Angle on the Bow" which is the angle that the ship presents to me. I used geometry just a couple months ago when I was building a wood shed. I calculated the slope of the roof and then had to calculate the angle to cut the boards so that they would match up, and then cut the end at an angle so that the face would be vertical.
I have a BS in Mechanical Engineering and am working on my MS in Mechanic Engineering (emphasis on fluid mechanics). Mechanical engineering encompasses many topics such as thermodynamics (of which I took three undergrad courses and received an A-, B- and A-), heat transfer (A), fluid mechanics (A), solid particle kinematics (A-), and strength of materials (B+). My 16 years of experience in the Navy working on nuclear submarines has reinforced my knowledge of thermodynamics and other topics.
I have developed several databases over the years. My most current one tracks over 400 students and 100 staff members enrolled in over 50 courses at any one time. It can generate reports based on classes currently enrolled, show which students are missing required courses, generate course completion reports and a variety of other reports. A significant amount of VBA is used to calculate various items, such as student's age based on DOB, class grades based on quiz/test scores and their weighting factor.
I have been using MS Excel since 1989 when I worked at Raytheon as a co-op student in college. I have developed complex spreadsheets using various formulas to calculate profit and loss for business plans, as well as using conditional formatting to make certain cells stand out under certain conditions. I have created pivot tables, charts, etc and have at one time or another used almost every feature in Excel.
I have been using MS Outlook for years now. The US Navy (my employer) uses it for their email system, and I use the calendar function to plan my day. I give all my employees access to my calendar to view my schedule, and they send me meeting invites for a variety of meetings. I use the task feature to keep track of my projects and sometimes I assign task to other people to perform. I have a variety of rules to move incoming emails to various folders to keep my emails organized and I also have a rule to open up a dialog box to alert me to important emails.
MS Powerpoint is used to create presentations for training or to update your boss on a project you are working on. I have created hundreds of presentations in my career. These presentations have included charts, tables, text, animations, transitions, etc. I have used slide masters to setup templates so all my slides look the same and therefore don't become distracting.
I use MS Word on a daily basis in my job. I have created documents with a table of contents that is automatically generated from using standardized section styles, page numbering. I have used footers that automatically number the pages, and sections, used outlines, numbered and bulleted, formatted text in almost any way imaginable. MS Word is not just an electronic typewriter. With a little knowledge you can easily format a document with professional results and I have used almost all the features in it at some point in my life.
Physics covers a variety of topics, to include Newton's laws of motion, optics, electromagnetic and sound wave propagation. Having a degree in Mechanical Engineering helps me understand many of the topics in physics in more depth than physics traditionally covers, which helps me find ways to relate the topics to the student.
Another useful tool to a submarine officer is trigonometry. While observing a surface contact through a periscope, I can calculate how close a contact will come to us based on his angle and range. By calculating the sin of the angle and then multiply by his range I can calculate "Distance to Track" which is a measure of how close the ship will come to us. Other useful parameters can also be determined by calculating the sine and cosine of the target's angle, such as range rate, which can tell me when the target will get to certain points.
