This really is a nice visualization and helped the audience feel at ease and assured them that&#8211;if they pay attention&#8211;they will be able to follow this talk (here is a big generalization: this is something we are not so good at in math, helping our listeners feel like we actually want them there).<\/p>\n<p>&nbsp;<\/p>\n<p>Dr. Kleinberg was successful in showing how mathematicians and computer scientists think about abstract networks and how general approaches developed in graph theory can be used to approach problems in many areas of congressional concern. How do we identify the most critical nodes in a network? The most vulnerable edges? He talked about protecting our electric grid (a network we want to protect), and controlling the spread of disease (a network we want to disrupt).<\/p>\n<p>One application that I think the audience really appreciated focused on using mathematical ideas to find <em>early<\/em> indications that (parts of) our large banking system may fail. He showed a nice slide illustrating that certain types of data only show an <em>immediate<\/em> threat, whereas a more heterogeneous collection of data shows fragility in the system earlier, and how the spread amplifies as the trouble spreads. Finding earlier signals could have prevented the great recession of a decade ago, or at least given forewarning and thus we could have worked to minimize its devastation.<\/p>\n<p>He also discussed online social networks, and how information spreads over the internet; issues important in DC as we approach another election and examine the role social media played in our last presidential election.<\/p>\n<p>If you are inspired to learn more, you can check out his book <a href=\"http:\/\/www.cs.cornell.edu\/home\/kleinber\/networks-book\/\"><em>Networks, Crowds, and Markets: Reasoning About a Highly Connected World<\/em><\/a>, which is based on an inter-disciplinary course that he teaches to undergraduates, requiring no formal prerequisites.<\/p>\n<p><a href=\"https:\/\/stevens.house.gov\/\">Representative Haley Stevens\u2019s<\/a> office secured the room for our briefing, and helped with logistics.

This one was no different and several of them asked great questions. Interns are normally college students (who are not math majors) and I feel good that they will go back to campus, having heard a great math talk, in Congress. I don\u2019t think many college students (or many Americans more generally, if I have to be honest) think about the importance of mathematics in so many areas of concern for the health of our nation. I hope they go back to campus with a positive attitude about the beauty and power of mathematics.<\/p>\n<p>Our next briefing will take place in December, and AMS President <a href=\"https:\/\/www.brown.edu\/research\/conducting-research-brown\/about-office\/about-jill-pipher\">Jill Pipher<\/a> will be our presenter.
