PPT-Ecology and You: Ecosystem Perturbation

Group 5 Lorelei Patrick Peter Stiling Riaz Khan Xavier Gonzales Adelaide Rhodes Facilitators Donata Henry and Conrad Toepfer Learning Outcomes Predict the outcome of perturbation on ecosystems. 1 What are perturbation methods Perturbation methods are methods which rely on there being a dimensionless parameter in the problem that is relatively small 1 The most common example you may have seen before is that of highReynolds number 57357uid m We may have heard the word “ecology” before without really understanding what it means.

It enables us to make progress when a physical system is too complicated to be analyzed exactly. The essential idea is to solve the behavior in steps. First we approximate the system by some simple Hamiltonian whose Schrödinger equation we know how to solve. Then we add the bit missed out, and use perturbation theory to calculate how our previous results (energy . Lecture 12. P. erturbation theory examples. HWK 4 is due Wednesday.. 150. Non-degenerate.
