My laboratory: Motorcycle Physics.
Welcome to PHYS1111/1112. I really like teaching this class in the summer 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.
Important course information: Six things to do before the first day of class.
|Examine the PHYS1111/1112 Syllabus|
|Acquire the textbook and online resources. 1) The textbook (required) for this course, Giambattista, 2nd Ed., is available as an e-book (recommended) through Connect. 2) McGraw-Hill Connect (required). 3) Register for LearnSmart (student registration code: M8RQ-YQB7-6GK7-EEB9-6RV9, Sign up code: phys1111hackworth). Please note that you do not have to pay any additional fee for this. 4) 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.|
|Go to the Aleks website and register for the custom math refresher for College Physics I've created for you (our course code is: Math Prep for College Physics 9QFCT-LQDW3). Aleks is an inexpensive math tutorial that is not mandatory, but I will award 10 points for anyone who completes the tutorial prior to the it's close (during the first week of class). In prior years there has been a nearly 1:1 correspondence between "A's" and students who completed at least 75% of the tutorial. This tutorial is probably the most meaningful thing that you can do to prepare for this class. We have no time in this course for math review. I will assume that you are up to speed on day one.|

|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.|
