This page is for the one day version of the Cratering lab which is used for Cheng's summer SMART outreach program. ==== Main Differences From Intro Lab Version ==== * It is a 1 day, 3 hour lab for the summer SMART program. * Omit everything related to fitting and Chi-Sq. ==== Outline ==== - Motivation : Describe cratering and pose question of how would you estimate the yield of a nuclear bomb, or the energy of an asteroid that made a crater on earth or the moon? - Scientific Process : - Develop a specific and testable question to explore. - Use theory or build a model to describe how you expect the system to behave. Understand your underlying assumptions. - Design an experiment to test the model. - Conduct your experiment. - Evaluate how well your data do, or do not, match your model. - Use your model to predict something beyond the range you tested. - Test your prediction. - Use your model to estimate energies for the Sedan crater and the one that killed the dinosaurs. ==== Examples of Scaling Laws ==== * Metabolic Rate as a function of Body Weight. From the mass of a mouse to the mass of an elephant span 6 orders of magnitude. Corresponding metabolic rates cover about 4 orders of magnitude. * Average Life Span vs Mass. * Brain Mass vs Body Mass. * Aerodynamics. Wind tunnel tests. * Financial Markets.
