Assignments

   Students will be required to solve a number of problems. Each assignment will be graded
equally towards the total grade for the assignment contribution to the final mark. Assign-
ments are to be handed in by the specified due date, and will not be accepted past this
due date. Students that encounter unusual circumstances may be given permission for late
submission, but are strongly encouraged to contact the instructor prior to the deadline to
make arrangements.




                                               2
Examinations

   There will be three examinations, all of which will be written exams. The midterm ex-
ams are tentatively scheduled for the 16th of October and the 27th of November so that you
can receive your grade for the first exam before the last day to withdraw from the course
without academic penalty (Oct. 20th ). The final exam date will be announced later in the
semester. The midterm exams will cover all material covered up to the class preceeding the
examination, and the final exam will cover all of the course material.

Important notice

    If there are students in this course who, because of disability, may have a need for spe-
cial academic accommodations, please come and discuss this with me, or contact Disability
Services located in room 7-103.


Why Physics??????

    Some students in this class may be considering a degree in Physics, a joint or double
major involving Physics, or taking the course simply as a means to satisfy degree require-
ments in another stream of study. In any case, students may be wondering why Physics is
important.
    If you have found yourself asking “why” about a process, technology or event, you may
very well be a Physicist at heart. Physics deals with answering questions of “why” and
“how” things work at a fundamental level. Physics is the basis for most modern and future
technologies. Physicists have developed much of the technology that you and I use every
day. Here are some of the things you might be surprised to find out that Physics has brought
you over the years:

   • Dutch Physicist Christian Huygens designed the first internal combustion engine in
     1680. This is now a billion dollar industry.

   • In 1905, Physicist Albert Einstein developed the theoretical framework for lasers. In
     1954, Physicist Charles Townes demonstrated the first laser at microwave frequencies.
     This technology forms the basis for many industries including Telecom, CD and DVD
     players, etc., which are billion dollar industries world-wide.

   • Physicist John Atanasoff invented the first digital computer in 1939 based on vacuum
     tube technology. The modern computer industry is a billion dollar industry.

   • John Bardeen, Walter Brattain and Wiliam Shockley (Physicists) invented the transis-
     tor in 1956. This forms the basis for all modern electronics, including microprocessors
     for your personal computers, which represents a trillion dollar industry world-wide.

   • Physicist Tim Berners-Lee invented the World Wide Web at CERN in 1990 to meet
     the demand of efficient information sharing (first web browser).

                                            o
   • In 1895, Physicist Wilhelm Conrad R¨ntgen discovered X-ray imaging, which has
     become an invaluable tool for the practce of medicine.

   • Physicist Sir Peter Mansfield and Chemist Paul Lauterbur shared the 2003 Nobel prize
     in Physiology or Medicine for their work on developing the MRI, another invaluable
     tool used in the practice of medicine.

                                             3
    In addition to these accomplishments, Physics has brought us new frontiers in research
- for example nanotechnology. From the automobile engine to the World Wide Web, Physi-
cists have been and will continue to be integral in the development of future technologies.
If any of this excites you, you may well be a Physicist!

Information about careers in Physics

    So you find Physics exciting, but are not sure what you can do with a degree in Physics.
