Conduct n Classroom conduct n n n Please respect your classmates: keep quiet during class Bottom line: if you are not here to learn please go somewhere else (includes reading other course materials, web surfing/email, etc) or you may be asked to leave Cheating n the following actions are considered cheating n n n 09/06/11 copying another student’s answers (during class participation, assignments, or exams) having any materials in an exam other than those specifically allowed by the instructors the penalties are severe: see http: //www. uwo. ca/univsec/handbook/ Introduction 20

Some Advice for this Course 1) Don’t tune out n n for many of you, the 1 st sections will seem like review don’t be fooled: n there will be new material n later chapters build on the earlier ones 2) Don’t panic when things get complicated n n n 09/06/11 most problems can be broken down into simpler ones but you’ll need to understand how they fit together ask your TA or instructor for help in advance Introduction 21

Some Advice for this Course 3) Look at the derivations. . . at least a bit n n frequent complaint: Too much time is spent on derivations alternative: “just give me the equation”. But then: n you won’t understand its limits n you won’t be able to modify a formula for similar cases n you won’t learn to think like a physicist/engineer 4) Use the resources/do the work n n n 09/06/11 come to class, ask questions do the sample problems, ask your TA to workout the solution read the textbook Introduction 22

Ways to get assistance: n Help from people n n n Peer-tutoring: always available and encouraged Web. Ct e-mail n you can contact me electronically via the Mail tool in Web. CT. Or, as a last resort, use the regular emails n please allow 2– 3 working days for a response n n Resource room, Material Sciences Addition. Times to be announced – multiple times to be designated Private Tutors n 09/06/11 The Dept. of Physics & Astronomy (http: //www. physics. uwo. ca/) has a list of tutors Introduction 23

Make-ups n Labs: n n 1 lab can be skipped without penalty in Fall term no make-ups see the lab manual package for more details Tutorial Tests: n n n 1 test can be skipped without penalty no make-ups if you skip more, you’ll need documentation from your Dean 09/06/11 Introduction 24

What is Physics? n You will get different answers from different people n Several possible answers: n n The science of matter and energy and their interactions Physics is the study of nature at its most fundamental level By Isaac Asimov “Don't you believe in flying saucers? Don't you believe in telepathy? — in ancient astronauts? — in the Bermuda triangle? — in life after death? No, no, no, and again no Don't you believe in anything? “ "Yes", I said. "I believe in evidence, in observation, measurement, and reasoning, confirmed by independent observers 09/06/11 Introduction 25

What do Physicists do? You have learn about some areas in High School (e. g. , projectile motion, Newtons laws, electricity) ⇒ but there are much more! Physicists… • study atomic particles and their collisions • investigate galaxies far away, • study meteorology and global warming; • build satellites, • study the aurora, • improve medical instruments • develop complex theoretical basis to connect different area of physics • examine matter with light, electrons, ions and positrons To apply your engineering skills, and to interact with other scientists, you will need the basics of Physics. Providing you with these basics is the purpose of this course. 09/06/11 Introduction 26
