Barbie dolls are not real people. The pictures of actors and models in magazines are barely real people (thanks to Photoshop). The actress in this car commercial is not a real scientist.
It does, however, show anyone watching commercials during the NCAA Men’s Basketball Tournament a stylish woman of color driving a nice car and doing complex-looking mathematics* in her head.
It shows someone who is not white, not male, not bearded, not with crazy hair, not with disheveled clothes, not with sub-par social skills doing complex-looking mathematics* in her head.
As we increasingly recognize that recruiting and retaining a diverse STEM workforce requires presenting individuals in that field with whom they can identify, we have a car company showing us that. This actress may not be a real scientist, but my four-year-old daughter won’t know that her concepts of who can be a scientist will have been expanded positively by a commercial while Daddy watched Duke play basketball on TV.
*I do not have the gift for going “oh, that is X equation” on sight. So, I will leave it up to you, dear readers, to evaluate the actual complexity and accuracy of the mathematical imagery.

Also incredible that she can write out equations on the driver’s side window while driving…
Especially without using her hands.
It’s about time that real scientist be recognized in media.
