Willow Springs International Raceway - Solo GT Light Race. The Physics of Motorcycles.

Hello - Welcome to PHYS211/212. I really like teaching this class and I hope that you will enjoy taking it.

I have always been interested in Physics because I have always been curious about how the things worked. Physics answers those questions. My interests: climbing, motorcycling, skiing/snowboarding, and professional audio all involve visceral physics - the challenges are often in the form of physics problems that you solve with your mind and body. If you are interested in my adventures in visceral physics (humiliations galore) check out motorcyclejazz.com, music, or my Facebook.

As an applied physicist I have been able to participate in many of the activities I enjoy at a professional level. Experience in acoustics and audio engineering formed the basis of a long career in professional audio. I hold an expert motorcycle roadracing license and work as a test rider/feature writer for a motorcycle.com and motorcyclejazz.com. I am or have been a contributor to several motorcycle, music industry, climbing and ski industry publications (links to some of my work are listed below).

My greatest desire (ok - not my greatest desire, but close) is that you come share the view that physics as fun and worthwhile. Physics is not a particularly difficult subject if you can master a few basic principles. It's front loaded though, so maximum effort in the beginning yields big dividends later.

Please do not hesitate to ask me physics questions that are related to things that you are interested in. This course it will be a great success if you develop a better understanding about things that you enjoy as a result of having been here.

Office hours: PS 117B as needed after class or by appointment.

Important course information: Five things to do before the first day of class.

1	Examine the PHYS211/212 Syllabus
2	a) Acquire the textbook and online resources. The textbook for this course, University Physics, Bauer/Westfall, 1st Ed. (required), is available as in hard copy or as an e-book online through the Connect website. b) Set yourself up with a McGraw-Hill Connect account (required): section 01 (Pocatello 10 a.m.), section 02 (Idaho Falls 5 p.m.). I highly recommend the e-book version of Bauer/Westfall which is much less expensive than the hardback and customizable. The license is good for two years and you may download and print the text should you desire a hard copy. c) Set yourself up with a Learn Smart account (free). Please note: Learn Smart will now be available directly from your Connect site beginning 1/15/13.
3	Check out the Exam Policy, FAQ, and Calculator Policy.
4	Be aware of my office hours: After class on Tuesday, Monday and Wednesday from 12 - 1:00, or by appointment. Please note - when the door to my office is closed I am unavailable.
5	Join our class Facebook page.

You need the Acrobat Reader for the notes.
