Physics 1111/1112
General Physics
Summer 15
Lecturer: Martin Hackworth

Instruction Assistant: Anna Hoskins



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: Five 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, 3rd ed., with Connect and LearnSmart is available as an e-book (recommended) directly through ConnectI 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 obtain binder-ready copy of the text should you desire at minimal cost. 2) the homework systemis McGraw-Hill Connect (required). If you bought the correct book at the bookstore a code for Connect is included. 3) You'll also need a laptop,tablet or other mobile device capable of working with Connect. 
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: QDKDW-NKKM3). Aleks is an inexpensive (you do pay a small fee for Aleks) math tutorial that, while not mandatory, is very useful. I will award 10 points for anyone who completes the tutorial prior to it's close during the first week of class. This tutorial is probably the most meaningful thing that you can do to prepare for this class if your math is shaky. We have absolutely no time in this course for math review. I will assume that you are up to speed on day one.  
Check out the Exam Policy, FAQ, and Calculator Policy.
Be aware of our summer office hours: After class (M, T, W, Th) or by appointment. Please note that Dr. Anna Hoskins will be in charge of office hours for this course. PS118, Approximately 11 - 2 Monday through Thursday. I have no office hours. Please note that I am unavaiable when my office door is closed.
