Numbers are names too

Numbers are names too In my last entry, Jonathan Foley asked an interesting set of questions: What is up with the whole abstract course nomenclature? Im sure this is great for MITers, but it seems rather arcane to the outside world. Why not call Course 9 Biology? Why not go the full distance and dispell with names, each student can be RFID tagged? I know he was mostly kidding, but since we do have a lot of numbering systems at MIT, and since they make no sense to anyone whos not here, I decided to ramble at some length about them today. Confession: I am actually talking about the numbering system because Campus Preview Weekend is coming up soon. I love CPW, and this year I signed up both to host a prefrosh (it could be you! if youre a girl) and to lead a tour of my UROP lab. But the one thing I really dont like about CPW is that I suddenly have to convert to telling people my major in words instead of numbers, and I always say the words too fast and people cant understand me and I have to repeat myself and I dont like it. (You try saying biology and brain and cognitive sciences five times fast.) So Im going to teach you the numbering system, and youre going to come to CPW and already know the numbers, and I wont have to look like an idiot. Everybody wins! Course numbers. Every major at MIT is assigned a unique identifier. Most commonly, this is a number, but a few departments have letter names or letter modifiers. Students at MIT almost exclusively refer to their majors by number unless they are talking to someone whom they suspect does not know the numbering system. I made a super-handy chart listing all the department numbers and all the sub-department majors, including the number of people who were awarded a degree in that major/sub-major in 2005. (Yes, I made it in Word. Yes, I do know how to write HTML, more or less, but I didnt feel like it.) FYI, undesignated sort of means same degree, fewer classes many people, for example, pick up an undesignated major as a second major. The actual number assigned to each department is a matter of historical contingency, and doesnt relate to the content of the department or the time period it was originally formed. In that sense, then, Jonathans right biology could just as easily have been course 44 rather than course 7. The numbers are pretty arbitrary. I would note, however, that doesnt mean theyre stupid after all, the actual words given to nouns in spoken languages are also a matter of historical contingency and arbitrary assignment (we call it biology because the ancient Greeks used the root bio to refer to living things, but they could just as easily have used something else). So, arbitrary, yes. But its the system we use, and its a pretty effective shibboleth, if I do say so myself. Other Questions. 1. M commented, 4 classes per semester It does not look strikingly difficult to me, but maybe because I havent had any experience with psets. It is a little harder than it looks. :) Each unit is supposed to be equivalent to one hour per week, so a typical 48-unit schedule is designed to take up almost 50 hours a week between class, lab, and homework. 2. M also asked, Mollie, Im doing the IB course with HL Math, Chem ang Bio. Say if I get admitted to MIT, I will probably have covered classes like introductory statistics. Can I get credit for those classes and bypass them? My teacher says if Im going to schools like MIT, I should probably not bypass any classes, especially if that class is lab-based. What do you think? Julie answered for me: And your teacher is right: unless the MIT class offers an advanced-standing exam and you pass out of it, its better that you take the class again at MIT. MIT usually does not offer credit for classes taken elsewhere, and for good reason: MIT classes are extremely demanding and often are not matched in rigor and content by other institutions. Ill add a few things. First, the classes youd take in high school might not be equivalent in subject matter (not just difficulty, but actual subject matter theyre different) to the courses at MIT. In my statistics class (9.07), we spent a lot of time on tests like ANOVAs, t-tests, and F-tests. In Adams statistics class (6.041), they spent a lot more time on really obscure probability and assumed strong familiarity with multivariable calculus. Its unlikely that a high school course would cover both those ends of statistics with enough depth for you to test out. Second, advanced standing exams are usually available for a limited set of classes, so not all classes can be tested out of. Youll get a better idea once youre here, particularly if you speak to the undergraduate coordinator of your intended department. 3. Dan asked, Whats the difference between organic chemistry, molecular biology, and biochemistry? They all sound so darn similar. I may sound dumb to some people for asking this, but who cares, right? And Jonathan Foley answered, They can be organized in terms of content and abstractness. Organic Chemistry deals with the chemistry of carbon containing molecules. While some focus on biologically relevant reactions, it principly the study of a class of chemistries rather than biology. Biochemistry deals with chemical processes ocuring in living things (i.e. catalyzed by enzymes) like the reactions of metabolism; biochemists break down biological pathways to chemistry that is actually occuring in a particular process (eg. what amino acid residues in the active site of an enzyme catalyze a given reaction). Molecular biology typically looks at biological pathways from the macromolecule level (proteins, DNA, RNA), typically central molecular processes such as transcription, translation, cell cycleetc. In other words: Organic chemistry is chemistry, biochemistry is chemistry that pertains to biolgy, molecular biology is molecular scale biology. (Hey, do you guys want my paycheck for the week? What am I doing over here?) Ill merely add that Ill buy Jonathans description, and that its amazing how much detail its possible to use when learning material in upper-level courses. I went into 7.23 (Immunology) thinking, Man, what is this class going to be about? Ive learned about antibodies and B cells and T cells a zillion times in other biology classes. I just dont know what else there is to learn! And, um, whoa buddy, was I wrong. FYI: Immunology is really complicated. 4. Lizzy asked, So you said you had two professors e-mail you backhow did you turn down the one whose lab you didnt join? (I know my question sounds silly, but Im first afraid that if I try to get a position, no one will want meand second, that if I get any positions, Ill get more than one and I wont know how to respond to the labs I dont join.) Another question are there UROPs at the other biomedical research places in Cambridge, such as Broad and Whitehead? And finally, how does your boyfriend know the skiiers? (*is jealous that he does*) First, yes, there are UROPs at Whitehead (none at Broad that I know of, because the new building isnt done yet!). You just have to find an MIT faculty supervisor to get funding from the UROP office, and Whitehead faculty have appointments in the department of biology. Second, professors are usually pretty relaxed about getting new UROPs I dont think anybody would be offended if you got two offers and picked the other guy. After all, most of the professors are pretty good friends with each other. Personally, I think I just emailed the other professor and said I had taken the job in Morgans lab. The other prof, Yasunori, is on the same floor as my lab, and he still says hi to me in the halls, so I dont think he was too broken up over it! Third, Adam knows most of the US ski team because hes a nationally-ranked freestyle skiier, and hes gone to camps and competitions with all of those guys since they were little. (Hes probably going to Nationals again this year, which is over our spring break! Yay!) Im trying to twist his arm to get him to introduce me to the Flying Tomato, but so far no luck. 5. Wenhao Sun asked about the weather. Seriously though, how cold is it really? Ive heard people say its really really really cold, Ive heard that its just cold enough to complain, and Ive heard that its cool and breezy (but I heard that from a friend from Wisconsin, so Im going to take that with a grain of salt). I guess its a pretty opinionated response, so how about some numbers? Thanks! It does get cold here theres usually a week or two in January where the wind chill gets down around -10F (-23C), although most of the winter is much warmer. Boston is a lot more moderate than cold places in the middle of the country (like Columbus, Ohio, where I grew up), because we have a giant ocean next to us which keeps the temperature in check. I personally have very little sympathy for people who claim to not be able to live in Boston because of the weather (and, lord, those southern California kids love to complain). My prescription: a nice poofy jacket, an illegal space heater, and the Tech Shuttle. It also helps that most of the campus is connected either above ground or by underground tunnels. ;)
