Theme: Biodiversity: Eco-Math link through Linear Algebra A Brief Introduction Biodiversity and the Hudson River Flowing from the Lake Tear of the Clouds, North the Hudson River journeys 315 miles and drops 4,322 feet in elevation before emptying itself into New York Harbor. The Hudson River is home to diverse populations of fish, birds, and mammals that cohabit and compete among themselves for resources. Recently the American shad, Atlantic sturgeon, river herring (blue back herring and alewife), American eel, and largemouth bass are in decline. Intense economic harvesting pressure and overexploitation cause coastal and marine species to decline. Therefore, harvesting and fishing should be managed properly and carefully to avoid decline of current population. Food web analysis provides important information regarding the nature of competition among various organisms. Cluster analysis in graph theory is a popular method to seek partition of a given data set into several clusters so that the data points within the same cluster are more similar than those belonged in the separate clusters. In this project we will use cluster analysis using the concepts of linear algebra to study the competition among various species in a given food web, in particular, competition among various Hudson River species. Students will find a partition of the competition graphs based on the Hudson River food web such that the strength of competition (for shared preys) between two clusters (two groups of predators) is as low as possible; however, the strength of competition within the same clusters is as high as possible. Big Idea behind this project Study and analyze Hudson River Food Web and its competition graph to interpret the strength of species competition. Particularly we will be exploring the followings: • Which predator species are more connected than others? • What happens if a specific species (particularly, a prey) dies out? Particularly, how does the removal of a particular species affect its predators and also the overall competition among all predator species? I Students Learning Outcomes 1. To solve systems of linear equations using matrices. 2. To identify and use vector properties (spaces, subspaces, bases, inner product). 3. To identify properties of matrices (inevitability, eigenvalues, eigenvectors). 4. To use computer technology to solve problems. 5. To learn how to apply core mathematical concepts (particularly eigenvalues and eigenvectors) in solving real-world problems. 7. To understand interdisciplinary approach and the significance of it in real-world applications. General Education Learning Goals 1. To understand interdisciplinary approach and the significance of it in real-world applications. 2. To address a problem and resolve the problem with scientific methods.

Physics, as one of the natural sciences, aims to discover the fundamental laws of the universe. Using theoretical and experimental methods, physicists study the basic structure of matter, space, and time. Knowledge of these laws allows us to understand the fascinating world of natural phenomena as well as to create new technologies that benefit every aspect of human life. The main branches of classical physics are mechanics, thermodynamics, electromagnetism and optics. In PHYS 1.3/PHYS 1441 we will explore the first two branches. The topics we will discuss in this course include Newton’s laws of motion and universal gravitation, the motions of planets and satellites, the properties of liquids and gases, and the nature of heat. In this course we use tools of calculus such as derivatives and integrals.
