ed. Wiley 2005).
Homework system and electronic text: WileyPlus.
INSTRUCTOR: Victor Karpov
Phone: (419) 530-4622
Office: MH 5012
Hours: MW 1:00-4:00 or by appointment
Official prerequisite: Physics 2130 (Mechanics, Heat, Sound)
Recommended prerequisite: Math 1860 (Calculus II)
CLASS TIMES: Class meets MWRF from 11:00 to 11:50 AM for lectures, exams, plus problem sessions on Tuesdays and lab at various times. You must register for a Tuesday discussion group, plus a lab section. Lectures will be MWF in MH1005; there will be an exam or quiz ALMOST every Thursday in DC1019 (check syllabus). The final exam will be during the week of 12/9/2007 in DC1019; exact day and time TBA.
SUBJECT MATTER: The full sequence PHYS2130-2140 provides an introduction to the fundamental concepts of physics. The material for PHYS2140 is contained in Volume 2 of the text, which is one of the most widely used physics textbooks in the world. The division of topics in the text is roughly (a) electromagnetic fields, (b) optics, and (c) atomic and nuclear physics. Of these textbook sections (a) is the largest, because so much of modern science and engineering (from computer chips to lasers and solar cells) is based on the use of electromagnetic fields and waves. The propagation of these fields in space and time is governed by the four equations known as Maxwell's Equations. However this division of topics is becoming outdated. From a fundamental point of view, the subjects of the course are the structure of matter and the laws of nature. In a nutshell the world is made of protons, neutron, electrons and photons; these interact with each other by means of the gravitational, electromagnetic, and nuclear interactions. The principal goal of this course will be to achieve an understanding of these concepts and their applications. Classroom examples and assigned problems will be chosen to illustrate the general ideas and the ways they are applied in practice, not to provide a catalog of results or methods.
STUDY ADVICE: It is very important to keep up to date in this course, doing the reading and the assigned problems on time. When doing the homework problems, after reading the chapter, try to avoid looking at the book if possible. Your first thought should not be "What formula can I find that gives the thing they are asking for?" Instead, ask yourself (1) "What basic principle applies to this problem?" and (2) "What equation does that principle give me in this particular case?" Once you have written down the one or two basic equations that apply to your problem, the solution then follows from straightforward mathematics, usually just elementary algebra. The goal is to learn the general principles of physics and how to apply them in a variety of situations, not a list of standard procedures for solving a certain set of problems, because that list will be out of date tomorrow. If you master the general principles and the methods of applying them, you can in the future go beyond textbook examples to solve whatever problems you encounter.
GRADING: The course grade will be made up of the following components,
weighted as shown.
Final exam 20%
Midterm exams (3) 30%
Quizzes (7) 20%
Daily quizzes 10%
Laboratory 10% (But you must pass the lab to pass the course.)
Grades are based on absolute standards, not on a "curve": there are no predetermined percentages of A's or of F's. Our goal is that everyone earns an A! Note that the current University Catalog (p.23) defines C as the lowest "acceptable" grade, even though grades from D- through C- are passing. The target grading scale for PHYS2140 for Fall 2006 will be as follows:
V. G. Karpov ** Fall Semester 2007
There are three required items:
1. The lab manual (Laboratory Experiments for Physics 2140).
2. The Turning Technologies RF classroom communicator.
You can't share these with anyone and you can't do without them. You must have your own RF remote unit (like a TV remote control). If you took PHYS 2130 in Fall 2005 with Professor T.J. Kvale, then you should already have this unit. Otherwise you should be able to buy one from the UT bookstore (perhaps a used one at reduced price). Always bring your remote with you to lecture -- it will be used to take daily quizzes, which will be part of the course grade.
3. The online homework system
You must have access to the online homework system, WileyPlus. Again, if you took PHYS 2130 in Spring 2005 with Professor T.J. Kvale, then you should already have this access. You need only go to http://edugen.wiley.com/edugen/class/cls42765/ and register for the new semester, Physics 2140. Our homework assignments must be submitted there and they will count toward your course grade. This system is designed especially to accompany our textbook, which is "Fundamentals of Physics" by Halliday, Resnick and Walker, 7th edition, Volume 2 (Wiley, 2005). In fact, WileyPlus gives you access to the entire textbook plus the Student Solutions Manual (ssm), and the Interactive Learning Ware (ilw). Thus if you prefer, you need not buy a textbook at all.
There are three ways you can purchase access to WileyPlus if you don’t already have it:
(1) You can buy it on the Internet directly from John Wiley and Sons publishers for $56.95 at their website, http://egradeplus.wiley.com. (You click on "purchase a registration code", then "physics", then "Halliday", then enter OHIO and select UNIV of TOLEDO, and then you find you have a shopping cart in standard web-purchase style.)
(2) You can probably buy it at the UT bookstore.
(3) You can buy "Fundamentals of Physics" Volume 2 by Halliday, Resnick and Walker, 7th edition, new at the UT bookstore, with the WileyPlus included in the package. This is the most expensive of the three, but has the advantage that you have a real book to keep, which will be useful to you as a physics reference book for many years.
Instructions for WileyPlus registration will be given in lecture.
For the textbook alone the ISBN is 0-471-42960-0.
For the textbook with WileyPlus included the ISBN is 0-471-69226-3.
