Being a Materials Scientist, I get this question a lot. And I hate getting this question because the answer is exceedingly obvious, but also exceedingly vague.
Allow me to illustrate with a brief excerpt from a representative (though fictional) conversation that I’ve had with basically every non-materials scientist I’ve ever had to make small talk with. (And if you’ve missed out, just let me know, and I’ll be sure to let you experience the awkwardness first hand)
“Hi Harold, I’m Colleen, pleasure to meet you.”
“Hi Colleen, uh…nice to meet you too. Um…so what is it that brings you to Chicago?”
“Well, I moved here about a couple of years ago, and I’m here on a public health fellowship to try to improve nutrition and reduce the incidence of obesity in the poorer neighborhoods of Chicago.”
“Oh wow. That’s really awesome. How do you like it?”
“It’s good. Pretty rough having to deal with red tape and Chicago bureaucrats, but there’s a huge need in these communities for better dietary education and access to good food, so I love it. How about you, what’re you doing in Chicago?”
“I’m a grad student in materials science at Northwestern.”
“Oh cool… What is materials science, exactly…?”
“Uh…materials science is the…study of materials…”
“Oh, um…that…sounds…neat?”
See!? Obvious answer = Totally non-descript.
Part of the problem is that Materials Science is a _huge_ field. It’s pretty hard to describe in just one sentence. The other is that outside of materials scientists, no one uses the term “materials science” to describe what are basically materials science research fields. Instead, you hear about specific areas of materials science such as “nanotechnology” or “solar cells”. And finally, well, the statement _is_ pretty vague.
Some people like to use “Materials Science is the study of ’stuff’ “, but replacing one vague word (”materials”) with an even vaguer one (”stuff”) doesn’t exactly serve to clarify matters.
However, I think I’ve come up with a slightly better (if still incredibly vague) one-line definition.
“Materials Science is the study of the ’stuff’ that the objects around you are made of”
So what do you think? Does that make slightly more sense? It doesn’t roll off the tongue particularly well, ** but I think the extra time required to say it gives the listener the chance to parse through all the vagaries. (It’s FEATURE, not a bug!)
If it does, here’s a little quiz.
What is it about the following objects, that a materials scientist would be interested in?
1) Tennis racquets
2) Automobiles
3) Laptops
4) Medicines
5) Fuel cells
** “Materials Science is the study of the ’stuff’ that other ’stuff’ is made of” is a bit more pithy and has alliterative appeal, but keep the two ’stuff’s straight can be a bit tricky, particularly if the listener has been imbibing a bit.
** Why not just “Materials Science is the study of what the world is made of?” Because, while “what things are made of” is indeed an interesting question, there’s much more to a materials science than just identification. Just wait and see…
