Tier II NATS class requires completion of two tier I classes Math involved at all stages – but emphasis will be on concepts Familiarity with: Algebra – manipulating equations Basic Exponents e.g. solve 2x=4 Very basic trig. e.g. know what sin, cos and tan mean.Acalculator/computer/iPhonethatperformsthesefunctionsAcalculator/computer/iPhonethatperformsthesefunctions Familiarity helpful: Astronomy, geology etc… Most of all – a willingness to think! We can help anyone who wants to help themselvesPYTS/ASTR 206 – Introduction17zYour last science class?Your last science class?z You might not even like science …but you’ll be dealing with scientific decisions for your wholescientific decisions for your whole life e.g. what will society do about this… Where will we get our energy from a few decades from now? What are acceptable pollution levels? How much should we spend on the space program? Any guesses on the current amount?? When someone says their results are scientific – what do they mean?PYTS/ASTR 206 – Introduction18z More general comments…z In the classroom Use common sense and courtesy Turn cell phones and other communication devices off!
