Question me an answer.

Question me an answer. PROPOSTION. Youve been reading this blog all this time without ever getting to know me. I mean, the real me. On Friday or thereabouts, Im going to do an entry introducing myself in a survey-type format. If you have any personal questions youd like me to answer, just leave them in a comment and Ill let you know. DID YOU KNOW? The entry title comes from some fantastic old 1970s movie that my grandfather had on one afternoon while I was growing up. All I remember is a guy in a paisley suit dancing around on a dock with a Vietnamese childrens choir and singing even though your answer may be wrong, my question will always be right! as they sing things like 1776! and he replies When did Columbus sail the ocean? and the song goes on like this for like 23 minutes, because there was a tap dance break or something in the middle, and at the end of the song the Vietnamese children are so annoyed by this guy that they push him into the river, which he totally deserved, and he just sits there splashing for a while and the harp plays festive arpeggios that lead us into the next scene. Has anybody seen that one? But I digress. ANONYMOUS QUERY! Youre a chemical engineer student, right? I really love chemistry, and I also love building and planning things (I make my own little doomsday devices)so Chemcials + engineeringcan you tell me what a real chemical engineer would do? Ive always been meaning to do the how does a chemist differ from a chemical engineer? entry, and now youve gone and given me an excuse. Look what youve done now. The short answer is the old adage Chemical engineering is the practice of doing for a profit what an organic chemist does only for fun. Well, thats not entirely accurate, but it is true that the work done by a chemical engineer usually vastly differs from that done by an organic chemist. Chemists usually concern themselves with work at the molecular levelcharacterizing a new metal-ligand catalyst via spectoscopy (5.04), finding the best set of reactions to synthesize a particular drug (5.13), or determining the exact geometry of a molecules electrons during a chemical change (5.60 and 5.61). A chemical engineer isnt going to be concerned so much with exactly what molecules look like or how they react, but rather what their gross properties are and how to optimize these reactions for research and industrial applications. For example, as you might know by now, my job as a chemical engineering researcher is to turn turkey carcasses into oil. Now, my grad student Andy and I already know how the turkey carcasses turn into oil, kind of you just heat them to 500 C, magic happens. And we know whats causing a problem in this processthe normally-delicious Maillard reaction is forming giant brown-black polymers akin to bread crust in the 250 C reactor. However, to solve this problem, were not really looking at the Maillard reaction at the molecular level. Were considering it basically only in the context of glucose + glycine = ugly black polymer. Rather than trying to determine theoretically how we might prevent the Maillard reaction, were varying the parameters of the reactor used and measuring the output and composition of the products. Our work is not so much theoretical as practical, and the questions we ask are not What cofactor could be added to slow down this reaction? but How can we detect the presence of glucose and glycine in our final reaction mixture? or How can we best model the fuel companys reactor in our design? A lot of chemical engineering is data analysis, it seems. This semester Ive spent a good four or five hours poring over Excel spreadsheets every week. MATLAB is also a major component of many Course X classes, much to the chagrin of programming-averse sophomores. Accordingly, the classes in chemical engineering emphasize real-world problem solving and situation analysis just as much as they do textbook examples. In 10.301: Process Fluid Mechanics, half the course was spent fitting viscosity data to smooth curves and verifying particle settling rates, while the other half was spent in a theoretical discussion of shear stress. This week in 10.302: Transport Processes, I have just about the most awesome problem ever to solve, involving the design of a ceramic plasma coating implement that operates at 10,000 K with a convective coefficient of 30,000 W / m K. Unlike some chemistry classes, in which youre just oxidizing your primary alcohols all night, I can always see exactly how what Im learning might be applied in industry. And what does a chemical engineer do in the real world? Well, according to career fair, a chemical engineer might work for an energy company like Shell or BP, or a pharmaceutical company, which would be just perfect with a degree in the newly-created Course 10B: Biochemical Engineering. Heck, maybe theyd even work for a chemical company. One thing thats pretty cool about any engineering major at MIT is that you end up getting, through your required classes, quite a bit of experience with other types of engineeringin particular, a lot of what you see in Course 10 relates closely to Course 2: Mechanical Engineering and Course 3: Materials Science and Engineering. As a result, its possible to find a job with chemical applications in areas that would initially seem to be only tangentially related. So, in conclusion, Chemical Engineering at MIT is the most perfect major at any college, ever and opens a million doors to boundless possibilities limited only by your imagination. Okay, hope that helped, Anonymous if that it your real name. BONUS! More adventures in German grammar. Yesterday in German I we learned how to say number above 20, all the way up to 999,999. Then somebody asked how you say ten to the sixth. Zeun hoch sechs. apparently. Weve got our first major test am Donnerstag, and today was essentially a review for that occasion. About half the class was confused about when to use the accusative case for articles and pronouns until one student, who had spent last summer interning in Germany as part of the MISTI program, came up with this gem of a mnemonic Nominative: Er ist ein student. Accusative: Er isst einen student.
