If you go to Google Images, and you type in the word "modeling," if you are like me, you might expect to see all sorts of equations, diagrams, and software interfaces allowing scientists and engineers to model complicated things. Instead, from the public's perspective, or perhaps from the perspective of the advertising industry, modeling means to model clothing. Fashion. Runways. The above image is from Top Ten Modeling Agencies. At first glance, this type of modeling is something we might be tempted to dismiss as irrelevant to our supposedly higher ambitions within mathematics, science, and engineering. But, this type of modeling is ubiquitous and serves as a good way to talk about modeling to others. Why not talk about models by covering fashion? You probably have heard of a "model house" or a "model kitchen." This type of model refers to model as prototype. Rather than modeling a pre-existing phenomenon like automobile traffic or heat exchange, model as prototype brings in design as a type of modeling. The model house may be one you'd like to live in. The model kitchen gives you ideas of how you'd like your kitchen to look and function. So, if you want to explain what you do as a modeler to others, begin with common terms and experiences. Meet people on their ground, with their understanding of model. And wear something suitable like a well-designed pair of jeans. You might be surprised when the next day, your friend shows up wearing the same clothing. You have become a model.
