Part II: Surviving the First Year of College
This part covers the survival tips of the first two undergraduate years. So now you’re in college, and you have every intention to be a physics major (actually, what I’m about to describe applies to anyone who is taking a physics class, not just for physics majors). In most US universities, as a freshman, you do not have a major-specific academic advisor, mainly because most freshmen do not have an officially-declared major. What you would probably get during your first week is a ”generic” advising based on what you INTEND to go into. In all likelihood, assuming that you have all the necessary background, it is a safe bet that you would need the complete sequence of Calculus (typically a year, or 3 semesters worth). This would cover all the basic calculus and analytical geometry (level of Thomas-Finney), and towards the end of the sequence, may superficially cover more advanced topics such as vector calculus and partial differential equations. As a physics major, you will need more mathematics than this, and that includes a separate mathematics course in the two advanced topics that I have mentioned, and maybe even a course an complex analysis. These are the courses that you may have to take after you complete the calculus sequence (more discussion on mathematics in the next installment of this series).
The introduction physics courses can vary from school to school. Typically, the broad dichotomy would be Intro Physics with or without calculus. As a physics major, you would take the former. This means that, if you do not have any calculus background, you may have to delay your first physics class after you have at least completed the first semester of your calculus class (high-school students, take note of this!). The typical intro physics courses in US universities would be at the level of Halliday-Resnick. It is typically covered in 2 or 3 semesters and is intended to be a general survey of many different aspects of physics. These courses tend to be accompanied by laboratory work, which is intended to be an introduction to a systematic experimental study of various physics concepts.
I would like to expand on the importance of such laboratory work, mainly because for many students, this is looked upon as a waste of time, especially if the experiments and laboratory conditions are less than ideal. There are certain things that cannot be taught, but can only be acquired. These are what we call skills. The reason why one has to physically DO something during a laboratory session is to acquire such skills. This does not just mean physical skill, such as the ability to read an ammeter, to be able to perform a task with the least amount of errors, etc., but also mental skills, such as analytical ability to look at the object of the experiment and figuring out why certain things are done certain ways. This include the ability to critically analyze the experimental data to extract relevant information. Upon completion of such exercise, one must then be able to clearly explain in words and pictures (graphs) what one did, and the results. Again, such ability is important for obvious reasons and it is a skill that can’t be taught. It can only be acquired through practice!
Note that what I have described above is not just applicable to physics majors. Such skills that can be acquired are important to anyone, regardless of one’s major. In fact, I would make the assertion that acquiring such skills is MORE important for most students in a physics class than knowing the material. It is a fact that the majority of students in a physics class are not physics majors. Although the knowledge of physics is important as a foundation for other classes, for most of the students, the skills that can be acquired through physics classes and laboratories are the more valuable traits that they will carry with them throughout their academic life and beyond. The ability for critical analysis and knowing the reliability of data and results are important skills that are useful in all everyday life.
If you are an undergraduate in a US university, there is no excuse for not enrolling yourself in The Society of Physics Students (SPS). This organization is open to all students, not just physics majors. As part of your membership dues, you are a year subscription to Physics Today, a journal that practically all physicists read and contains timely information on the world of physics and physicists. You will also get newsletter and information specifically targeted for undergraduates like you, and also entitles you later on for significant discounts and even free registrations to attend various physics conferences. In other words, if you have even half a brain, enroll in this! The benefits are just too great to not to. Go to the physics department at your school and ask if they have a chapter of the SPS there. You can enroll via your school’s chapter. If there isn’t any, go to the SPS website at http://www.aip.org/education/sps/index.html and you may enroll there as an individual member. It is NEVER too early to be a member, so do it as soon as you are settled. If you are not in a US university, you may still subscribe to Physics Today by going to their website at http://www.aip.org/pt/
Throughout your first 2 years, the BEST thing you can do for yourself is to get excellent grades. This, I’m sure, goes without saying, but you have to realize that typically, these are the easiest and the most important courses you will see in your undergraduate years. They are the foundation that you will build on for your other courses, and they are the ones you have a better chance of achieving the highest grades. Do not be discouraged if you feel that at this stage, you are one of the many anonymous ”numbers” in a large class. Most classes at this level tend to be huge and it isn’t easy to distinguish oneself from the crowd (you will have plenty of opportunities to distinguish yourself later on). But do not let this stop you from seeing the instructor during his/her office hours, or using the Teaching Assistants if you need help. They have been PAID to do just that!
In the next installment, we will discuss the transition between the intro classes and the more advanced undergraduate classes, and your first tentative steps towards distinguishing yourself from other students.
