The Physics Minor Programme
The minor in Physics consists of (at least) six courses in physics along with (at least) two mathematics prerequisites MATH 151, 250, Calculus I & II.
Three Courses are prescribed:
The remaining three may be chosen from among the following:
Q: So, what good is a minor in Physics?
A: This is like asking, "What good is breathing?"
But seriously, there are several reasons to earn a minor in Physics as part of one's studies.
- One may wish to study physics as a cognate area for a technical or quantitative field such as mathematics or economics. The mathematical modelling of physical systems is an efficacious means of skills-building and preparation for advanced work in the particular discipline.
- One may wish to study physics as a cognate area for philosophy or theology. The modern sciences grew from Natural Philosophy and, of the sciences, Physics remains most close in spirit to these disciplines. Both the content — Nature's wonder and economy — and the process — model building — can be of considerable worth and utility to those who study philosophy and theology. Those whose sights are set on obtaining advanced degrees will find the study of physics especially beneficial.
- Some intend to proceed from Ave into a technical career, perhaps engineering or one of the many applied sciences. Persons with these intentions should take the minor in order to acquire the content knowledge and training which will facilitate their further studies or direct entry into technical fields.
- An often overlooked, but rewarding, career is Patent Law.
[There was a fella who worked as a patent clerk in Bern (Switzerland) about a hundred years ago. Things turned out rather well indeed for that chap.]
- There is strong demand for secondary school teachers of mathematics and the physical sciences. The minor programme in physics prepares and equips one to teach the content of high school and AP physics courses.
- Students intending to go to graduate school in biology will do well to take as many of the physics course offerings as their schedule permits. Modern biology relies heavily on experimental techniques and equipment, as well as theoretical and computational tools, that were originally designed and constructed to advance physics investigations.
- Music is nothing more than the propagation of correlated wavelike disturbances through a fluid medium. Music majors, take note!
- And finally, there are those who just think that Physics is really cool. These people should take PHYS classes for the sheer joy of it!
The FINE PRINT
The physics minor programme can augment most degree programmes at AMU with few scheduling repercussions.
The conventional strategy is the "SLOW and STEADY" approach, wherein one takes Calculus I and II in the Freshman year, University Physics I and II to satisfy one's Core Science (with lab) requirement in the Sophomore year, and then one (or more) upper-year physics class in each semester of one's Junior and Senior years.
At most this might require a wee bit of juggling to open up an elective slot in the final semester of one's Senior year, i.e., pushing a major elective forward to the Junior year, or redistributing the PHIL/THEO 400 classes across the Fall and Spring terms.
One is permitted/encouraged to take two classes in the Fall Semester of one's Junior year, i.e., taking an elective concurrently with PHYS 323. This strategy also makes it possible to participate in the study-abroad programme.
The canonical means of inserting Calculus II into the Spring semester of the Freshman year which involves sliding the THEO 105/205 sequence back one term and taking HIST/POLT 203 in either semester of the Junior year.
An alternative and less desirable strategy is to overload — Who needs sleep, anyway?
More juggling - and some overload - is required of Biology and Music majors. Our recommendation is to take as many physics classes as your schedule allows and not worry about getting the minor. If your heart is set on getting the minor, then start planning early. [Transfer or AP credit will certainly help.]
Biologists: Take both CHEM 211/212, and PHYS 221/222 in your second year. It might prove necessary to overload in one (or more) term(s) to meet all of the AMU Core, Biology major, and Physics minor requirements.
Music majors: Please consult with your advisor (and PK) about how we might push the Core Science (Physics) classes forward into the Sophomore year, and shift music electives from the Junior to the Senior year.

Nobel Prizes in Physics Awarded
The 2010 Prize went to the blokes, Andre Geim and Konstantin Novoselov, who successfully produced graphene, a genuinely two-dimensional material. Graphene possesses exotic properties owing to a number of quantum mechanical effects and has tremendous promise for technological advances.
The 2009 Prize was awarded in honour of two revolutionary breakthroughs in optical technology. One-half of the prize went to Charles Kao for the development of the optical fibres now widely used in telecommunications. The other half was shared between Bill Boyle and George Smith for their invention of the "charge-coupled device" employed to capture light signals in digital-electronic form (i.e., digital cameras).
The 2008 Nobel Prize in Physics was awarded for investigations of symmetry breaking in elementary particle physics. One half of the prize went to Y. Nambu, for his seminal investigations of spontaneously broken symmetry in the context of elementary particles. Spontaneous breaking of a symmetry of the putative Higgs field is invoked to provide mass to the various constituents of the so-called Standard Model of elementary particle physics. The other half of the prize was shared by M. Kobayashi and T. Maskawa for their discovery of a means of describing elementary particles which incorporated a manifest breaking of the CP [matter--anti-matter , left--right mirror] symmetries. CP non-invariance is a pre-condition for the existence of a matter-dominated state of the universe (rather than equal quantities of matter and anti-matter), and is observed via subtle longevity enhancements of certain short-lived mesons.
The 2007 Nobel Prize in Physics was shared equally by Fert and Gruenberg for their independent discoveries of the phenomenon of Giant Magnetoresistance. Giant Magnetoresistance has had tremedous technological spin-off by enabling ever-increasing bit density in magnetic storage devices. Equally important, it constitutes an application of both nanotechnology and spintronics.
The 2006 Nobel Prize in Physics was shared equally by Mather and Smoot for their leading contributions to cosmology through the COBE [COsmic Background Explorer] satellite precise observations of the cosmic microwave background radiation.
