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
PHYS219 in one slide:
study of the dance of the charges and the fields
Charge Q
Current I=Qv
Electric field E
Electric force FE
Magnetic field B
Magnetic Force FB
F=mα
Charge acceleration α leads to EM waves:
Oscillating E, B that move with the speed of light c
it is a bright dance!!!

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.

Syllabus (more)
• Homework: The Computerized Homework in Physics (CHIP) system
is used: http://chip.physics.purdue.edu/public/instruct.html
• 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
Units of Measurement
A few exceptions: electron volt : 1eV=1.602x10-19 J
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
EMERGENCY PREPAREDNESS
– A MESSAGE FROM PURDUE
To report an emergency, call 911. To obtain updates regarding an ongoing
emergency, sign up for Purdue Alert text messages, view www.purdue.edu/ea.
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.
