Department Mission

Our mission is to teach students the scientific method so they can understand modern scientific descriptions of the universe and come to objective conclusions about the natural world. Like all members of the SI community we aim to educate the whole person, emphasizing the academic, extracurricular, and spiritual development of our students.

We would like to see graduates of SI ...

To this end, we strongly advise students to take all three of our core classes (Biology, Chemistry, and Physics) as well as a 4th year elective course.

Course Outcomes

Topics for enduring understanding

  • Physics is the study of the most fundamental laws of nature. Physicsts are concerned with the behavior of the universe and its constituents ranging from the smallest subatomic particles up to enormous galaxy clusters.
  • Physics is an experimental science, meaning that all theories -- no matter how elegant -- can be rejected if in conflict with the results of a single experiment. To quote Karl Popper: "Science may be described as the art of systematic over-simplification...In so far as a scientific statement speaks about reality, it must be falsifiable; and in so far as it is not falsifiable, it does not speak about reality."
  • Physicists should "get their hands dirty." Laboratory work allows us to interact with the world in a simplified, controlled way. There is a place for calculations and abstract mathematical manipulation, but this kind of effort should lead to a deeper understanding of the real world.
  • As important as the content of physics is the method: students with a physics education are expected to repeatedly ask and answer the fundamental question 'How do we know?'. Physics is not a dogmatic discipline: everything is up for grabs.
  • Physics is more than just the memorization of content: it is a framework for understanding the world as it is. To quote Nobel prize-winning physicist Richard Feynman: "You can know the name of a bird in all the languages of the world, but when you're finished, you'll know absolutely nothing whatever about the bird... So let's look at the bird and see what it's doing — that's what counts. I learned very early the difference between knowing the name of something and knowing something."
  • The rational world-view taught in a physics class will be more important to our students in their future lives than any specific course content.
  • One reason physics is so powerful is that a small set of core ideas can be applied to a broad range of phenomena.

Essential questions

  • Galileo Galilei once said "Mathematics is the language with which God has written the universe." Some modern physicists are proposing that the universe is "made of mathematical equations." Is it true? Is the universe made of math?
  • Are all the physical laws in the universe potentially understandable by humans? In other words: dogs will never understand algebra; is there some theory out there we ourselves could never understand? Or is the scientific method sufficient to understand everything we want?
  • Will physicists announce a complete "theory of everything" in your lifetime?
  • Is there more than one complete, consistent description of the laws of physics? Could an alien civilization create laws of physics as good as ours at describing the behavior of the world but which is fundamentally different in its approach? Do we ourselves work with more than one set of separate & consistent laws of physics?
  • Is there a "center" of the universe, or any absolute reference frame or priveleged position? How are conservation laws derived from symmetries in nature?

        • “You can’t break even.” [Allen Ginsberg]
        • During exchanges of energy, some amount is always converted into a random form (thermal energy). [common]
        • The entropy of a closed system is statistically bound to increase. [common]
      • Third Law
        • As temperature approaches absolute zero, the entropy of a system approaches a constant. [Wikipedia]
        • “You can’t quit.” [Allen Ginsberg]
        • If all thermal and kinetic energy is removed from a system, the system’s temperature is absolute zero.  Thanks to the Second Law, this state is impossible to achieve. [common]
      • “Zeroth” Law
        • If two thermodynamic systems are in thermal equilibrium with a third, they are also in thermal equilibrium with each other. [Wikipedia].
        • (Note that the “Zeroth” Law is a common-sense notion that was introduced as an axiom for philosophical reasons. We will not dwell on it.)

      • Energy is a “zero sum” game.
      • Like work, heat describes the transfer of energy between two systems.
      • Heat tends to flow from high temperature to low temperature systems.
      • Entropy is a measure of the amount of disorder in a system.
      • The ideal gas law written as PV = NkT and as PV = nRT are one and the same; the latter is written in molar quantities.
      • The density of water is about 1000× higher than the density of air
      • Entropy is a statistical description of the degree of disorder in a system.
      • The increase of entropy in a closed system is a statistical prediction.

Methodology

Instructional methodology

  • Instructors will use a variety of methods in order to achieve the highest and broadest possible understanding among the students. The methods can include, but are not limited to: standard lecture, problem set assignments, standard quizzes and exams, discovery and formal laboratory exercises, long and short-term projects, multimedia presentations, computer simulation, demonstrations, one-on-one instruction, peer instruction, “studio”-based instruction, and “Modeling” of the sort David Hestenes has promoted at Arizona State University.
  • It is understood that physics needs to be fun, approachable, and interesting. Instructors will, from time to time, share new discoveries, old ideas, and stories that capture the history, mood, and excitement we associate with natural science.
  • Instructors will deal head-on with student’s alternative conceptions of physics. As Randy Knight points out in his excellent book Five Easy Lessons,

“Students enter our classroom not as ‘blank slates,’ tabula rasa, but filled with many prior concepts…. Student’s concepts are rather muddled, not well differentiated, and contain unrecognized inconsistencies. By the standards of physics, their concepts are mostly wrong.” “Students’ prior concepts are remarkably resistant to change. Conventional instruction – lecture classes, homework, and exams that are predominately or exclusively quantitative – makes almost no change in a student’s conceptual beliefs.”

Knight’s solution is to follow the Five Easy Lessons: (paraphrased here)

  • Keep students actively engaged and provide rapid feedback. A short list of active engagement methods includes interactive lecture demonstrations, nearest neighbor discussion activities, collaborative group activities, computer-based laboratories or other guided-discovery laboratories, and take-home experiments.
  • Focus on phenomena rather than abstractions. Use experiential labs. Work inductively, from the concrete to the abstract. Ask the questions “How do we know …?” and “Why do we believe … ?”.
  • Deal explicitly with students’ alternative conceptions. Students have to recognize and accept that there really is a conflict between their wrong predictions and reality. Left to themselves, many students will brush the conflict aside as of no relevance.
  • Teach and use explicit problem-solving skills and strategies. These include interpretation, pictorial, graphical, and reasoning skills. Make explicit the assumptions, decisions, and reasoning that are part of an expert’s problem-solving strategy but which usually go unsaid.
  • Write homework and exam problems that go beyond symbol manipulation to engage students in the qualitative and conceptual analysis of physical phenomena. Balance qualitative and quantitative reasoning. Emphasize reasoning, de-emphasize formulas and equations. Deal directly with phenomena and observations. Derivations have little efficacy for students at this level.

In their Understanding by Design Handbook, Wiggins and McTighe describe quizzes and tests as “simple, content-focused questions that assess for factual information, concepts, and discrete skills.” Academic prompts are “open-ended questions or problems that require students to think critically, not just recall knowledge, and to prepare a response, product, or performance … under school exam conditions.”
