Comments:
I am an Analytical chemist at a biopharmaceutical company. I use it to calculate concentrations for buffers and sample preparation. I use it to calculate the kinetic energy and heat imparted to drug components during formulation to determine the effects of heat inactivation based on different rotational speeds. I use to process data. But most importantly, I use it to when devising investment schemes to make a profit off the money I set aside for a future retirement to have a seven figure 401K and savings/stocks. Explain that to your students. Or they can be ignorant and calculate how much time they can take off their sentence by good behavior. Math is important to everyone. It is the very foundation of all true science!
