PHYS 219 Fall semester 2014 Lecture 01: Course Overview Dimitrios GIANNIOS Physics & Astronomy Department Purdue University Course website:

PHYS 219: General Physics Course Description: A broad survey of electricity, magnetism, light, and modern physics for technology students, focusing on the examples and applications especially appropriate to the technology field with generally conservative use of mathematics but giving fully quantitative treatments on selected key topics. Instructor: Giannios, Dimitrios

The Historical Context Galileo’s work around 1620 starts the scientific revolution that culminates in 1686 when Newton’s Principia is published  theory for understanding motion and gravity By ~1750, a new topic becomes popular – Electricity – By 1850, the fundamental laws of Electricity and Magnetism are reasonably well established at the macroscopic level Maxwell’s unification of Electricity and Magnetism and the prediction of Electromagnetic Waves With this understanding, Newton’s Laws, classical Physics receive a new challenge!  Birth of Theory of Relativity  Quantum Mechanics are born

Course Syllabus Lecturer: D. Giannios; Office: PHYS 325; Office hours: 8:30-10:30 AM on Fridays or by appointment [ I will try to check s a few times each day throughout the semester. You are strongly encouraged to use Blackboard for PHYS219 to follow announcements, updates on the class and ask questions: u] u Recitations: Ajith Rajapaksha; Office Hours: TBD Lab Coordinator: Andrej (Andrew) Lewicki; Office PHYS 142; Course Web Page: You can find it at: Text: Vol. 2 of “College Physics – Reasoning and Relationships” by N.J. Giordano, Brooks and Cole (Boston, MA) 2013

Course Syllabus (continued) Lectures: 10:30-11:20 Monday and Wednesday in PHYS 112. Help me so that I can help you: Questions are encouraged before, during or after any lecture During all lectures, turn off your cell phones, pagers and laptops Assignments: The reading and homework schedules are enclosed This material should be read before attending lecture Recitations: 10:30-11:20, Friday in PHYS 112. The purpose of recitation is to allow a discussion of the homework problems. Laboratory: There is a laboratory associated with this Lab sections meet once a week; during the semester You will perform approximately 11 lab experiments Please consult your class schedules to determine when and where your lab section will meet. Lab Coordinator: Andrej (Andrew) Lewicki; Office PHYS 142;

Syllabus (more) Homework: The Computerized Homework in Physics (CHIP) system is used: The homework assignment for each week typically consists of ~ 10 CHIP Homework Problems. Using the CHIP web-based system, you can enter your homework answers into your CHIPs account The time cutoff for answering homework on CHIPs for full credit will be 10:30 AM on the Friday that the homework problems are due You can also submit ONE answer to any question within 1 day after recitation is completed (before 10:30 AM on Saturday) for 50% credit Exams: Three exams will be given (closed book) Exam I: Thursday, Sep. 25, 8:00-9:00 PM; PHYS 112 Exam II: Thursday, Nov. 6, 8:00-9:00 PM; PHYS 112 Final Exam: The Office of Schedules and Space will determine the date and location

Syllabus (last) Grades: There is one overall letter grade for the course, determined on the basis of 600 points as shown below. Two one-hour exams (100 points each=200 points total) Homework (150 points) Laboratory (150 points) Final Exam (during finals week; 100 points) Total 600 points Course Outcomes: The expected outcomes of this course are to develop an ability to identify, formulate and solve simple problems that require concepts from electricity, magnetism, optics, and modern physics.

Progress of science/engineering marked by the transformation of the qualitative to the quantitative using mathematics. The scientific world is quantified using four levels of mathematics Functional relationships: V=IR; Q=CV; F=-kx Dynamical Models: Differential equations Probabilistic Models: Boltzmann statistics, Fermi-Dirac statistics, etc. Fields: Electromagnetic field equations

If you feel uncomfortable with your math skills, please do something to improve them! Algebra Scientific Notation Simple Vector Concepts Some math you will need to know: One equation, one unknown Sine, cosine, tangent, exponents Pythagorean Theorem, geometry Exponential (scientific) notation

Units of Measurement

Metric Unit Abbreviation

Scientific Notation --Examples

How to learn the material 1. Read about it (read textbooks) 2. Listen to someone; discuss it (come to class, view You Tube tutorials, Wiki pages, etc.) 3. Work as many problems as possible (do the homework, plus more)

What Are Your Responsibilities? Come to class on time. Know all the pertinent information about the class, including: the course number instructor's name the date, time and location of all examinations Know the contents of the syllabus Have sufficient general knowledge to understand the course material Retain material discussed in class Give yourself time to think about the course material Ask questions about topics you are unsure about Know the course material well enough to understand the terminology used in homework and exam questions

To report an emergency, call 911. To obtain updates regarding an ongoing emergency, sign up for Purdue Alert text messages, view There are nearly 300 Emergency Telephones outdoors across campus and in parking garages that connect directly to the PUPD. If you feel threatened or need help, push the button and you will be connected immediately. If we hear a fire alarm during class we will immediately suspend class, evacuate the building, and proceed outdoors. Do not use the elevator. If we are notified during class of a Shelter in Place requirement for a tornado warning, we will suspend class and shelter in [the basement]. If we are notified during class of a Shelter in Place requirement for a hazardous materials release, or a civil disturbance, including a shooting or other use of weapons, we will suspend class and shelter in the classroom, shutting the door and turning off the lights. Please review the Emergency Preparedness website for additional information. EMERGENCY PREPAREDNESS – A MESSAGE FROM PURDUE
