My Laboratory: the Visceral Physics of racing and a primer in Motorcycle Physics.

You are visitor number   to this site this semester.

Welcome to PHYS1111/1112. 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.

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 have worked as a test rider/feature writer for a motorcycle.com and currently motorcyclejazz.com. I am or have been a contributor to several motorcycle, music industry, climbing and ski industry publications (see below).

My greatest desire is that you come share the view that physics as fun and worthwhile. Physics, though initially intimidating, is not a difficult subject if you can master a few basic physical 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.

Take a field trip in visceral physics.

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

1
Examine the PHYS1111/1112 Syllabus
2
Acquire the textbook and online resources. The textbook (required) for this course, Giambattista, 2nd Ed., is available as an e-book (recommended) through Connect. McGraw-Hill Connect (required). You'll also need a laptop,tablet or other mobile device capable of working with Connect. I highly recommend the e-book version of Giambattista which is much less expensive than the hardback and customizable. The license is good for up to a year and you may download and print the text should you desire a hard copy.
3
Go to the Aleks website and register for the custom tutorial I've created for you (our course code is: Math Prep for College Physics KADKN-WHYHL). Aleks is an inexpensive math tutorial that is not mandatory, but I will award points for anyone who completes the tutorial prior to the it's close (around the beginning of class). Last year there was nearly a 1:1 correspondence between "A's" and students who completed at least 75% of the tutorial.
4
Check out the Exam Policy, FAQ, and Calculator Policy.
5
Be aware of my summer office hours: After class (M, W, Th) or by appointment. Please note - when the door to my office is closed I am unavailable.
