## NetLogo Activity, Monday, Week 2 - Epidemic on a Network

Which of two common network types is a more efficient "percolator"? In this activity, we'll build on the previous NetLogo activities, and build networks (uniform random and preferential attachment) over which epidemics will spread. Of course, percolation through a network isn't limited to epidemics; for example, we can use similar approaches to model the transmission of ideas, rumors, inventions – even religions – over social networks.

## Douglas Cullen

Doug Cullen is geosystems teacher in Fairfax County Virginia. As part of the geosystems curriculum he introduces his students to complex systems and systems modeling utilizing Stella. He is trying to include some agent based modeling (netlogo) to the curriculum to model some of the ways that human activities impact Earth systems. The geosystems curriculum also includes emphasis on state of the art technologies for studying Earth systems including image processing and analysis using Idrisi and ImageJ and the use of ArcGIS for spatial analysis.

## Michael Stueben

I am a math/computer science teacher at Thomas Jefferson High school for Science and Technology.

I began teaching in 1975. Somehow, mathematics, and high school teaching have taken over my life. They have

become my hobbies as well as my profession.

In 1998, the Mathematical Association of America published my book Twenty Years Before the Blackboard.

In 2006 I was awarded (by the MAA) the Edyth May Sliffe Award for Distinguished High School Mathematics Teaching.

I am currently interested in Java programming, genetic algorithms, and networks.

## Kathleen Murphy

Kate teaches Robotics, Advanced Robotics, Video Game Design and Development, Web-based Game Design and Development, and Problem Solving Strategies at KIPP Houston High School. She has an M.A. in Anthropology from the University of Michigan and an M.S. in Computer Science from the University of Wisconsin. Teaching is her fourth career. Prior to teaching she spent about 20 years designing and developing knowledge-based systems and experimenting with genetic algorithms.

## Mary Sagartz

Interested in math and computers in high school, I have a BA in math and computer science from the University of Wisconsin - Madison. I earned my Master's in computer science from the University of Illinois, Champaign/Urbana. The College of Engineering selected me as their finalist in the Excellence in Graduate Teaching.

After a stint at Sandia National Laboratories and another stint at child rearing, I began teaching at Annunciation Catholic School, where I teach computers to mid school students and robotics to 4th and 5th graders.

## Arlo Barnes

Arlo James Barnes, 15, will be a junior next year, possibly at the Academy for Technology and the Classics Public Charter Middle-and-High School [ATC]. He only dabbles in computing and programming but is always eager to help with teaching curricula based around such topics. He believes in a well-rounded education including studies of complexity, chaos, and networking, along with the classical disciplines and respect for all things living and otherwise. He has been involved in varying capacities with Project GUTS, the Santa Fe Complex, and other science-and-math-based organizations. In a team with three other high-schoolers, he competed in the 2009-2010 New Mexico Supercomputing Challenge. He plans to go to college and hopes to be more involved with the Santa Fe Institute in the near and far futures, and take a job in some science-related area, or with Google. This is his first time being at the Santa Fe Institute beyond the Gatehouse.
