In some ways, brothers Michael and Scott Coughlin are your classic odd couple.
Michael, 23, is intense and introverted, a skilled ballroom dancer as well as a scientist. Scott, 22, is easygoing and social, a sports junkie who often ends sentences with the words "and stuff."
But the two Burnsville natives have something major in common: a passion for physics. Indeed, their academic accomplishments put them among top scholars in the country, and both are studying gravitational waves as part of the same international research project.
The brothers say collaboration and support for each other, not competition, are key to their success.
"We're competitive about everything but our academic accomplishments," said Scott.
Growing up, that included everything from video games to sports.
"Nowadays, that would just set us back," said Michael. "Each of our successes pushes the other one forward."
Scott is a recent recipient of a prestigious Fulbright Scholarship, which will allow him to earn a Master's degree studying gravitational wave physics next year at Cardiff University in Wales. He will graduate from Northwestern University, triple majoring in classics, math and economics, this month.
