## Where do you use math in your profession?

One of the most difficult challenges that math teachers face today is motivating their students. This becomes more difficult when faced with the all famous question: "What am I going to use this for?"

Help me with some real world examples of modern day math. Please let me know your profession and what type of math you use to share with our students.

Thank you everyone so much for the contributions! They are great and I wasn't expecting such a turn out. My goal is to gain enough examples and to use them at the start of each lecture. I'm hoping that these examples in the beginning of class will spark the student's interest for the reaming of the lecture and to show that that we really do use math.

There is a difference between having to learn something and wanting to learn something. When we have to learn it we just try to get through it. When we want to learn it, this is when we make breakthroughs. Stimulate the interest in students so that they want to learn math and we increase our probability in someone discovering the next breakthrough.

Another one that is used a lot in photography is the angle of reflectance The incident ray, the reflected ray and the normal to the reflection surface at the point of the incidence lie in the same plane. These are both basic physics but it shows how we use such advanced concepts without even being smart enough to realize it : ) They are ll around us.
