In selecting a career, disposition is important, whereas in choosing a college you essentially take an iq test<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Aynslie: I thought it was interesting that the author talked about the rise of medication in schoolchildren and high schoolers. Maybe this comes from a decline in recess and breaktime as people get older.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Vanessa: Kids are all pushed to sit down in class and be serious all day. Maybe some kids don\u2019t learn best that way and need ways to release their energy that are different from seated concentration. Included anecdote about her brother who was diagnosed with ADHD<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Prof Littman: In early America, there was discussion about boys beginning school when they are 10 years old<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Vanessa: Scientifically we can understand when kids are best tailored to study and work (based on circadian rhythms) but society doesn\u2019t always listen to these scientific findings.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Nate: Schooling is often crafted to serve an institutional purpose rather than our own personal development.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Aynslie: It\u2019s interesting that later in college you aren\u2019t made to sit all day, but earlier on in elementary and high school you are made to sit and concentrate more often and for longer periods<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Chloe: what did people take away about the story in the repair shop from section 2<\/span>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Aynslie: I noticed he talked about packing a wheel bearing\u2026<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Vanessa: I packed a wheel bearing. We put a sticky grease lubricant in the bearings before putting them into the hub.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Bill: If you pack a bearing full of lubricant, the grease can\u2019t move around in order to cover more of the bearing surface. This can cause a bearing to wear down or overheat.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Abby: Motorcycle term from later in the chapter<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Prof Littman: It also mentions a transaxle. It\u2019s the combination of a transmission differential and an axle, which some cars like Porsches have. He also mentions a flat 6.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Nate: A flat 6 gives lower rev but more output.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Bill: In a Porsche, a flat 6 is horizontal but not vertical.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Prof Littman: We are also introduced in this section to Lance. What is his deal?<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Rashmina: Lance is the operator of the Porsche facility who the narrator works for, but he only gives the narrator busy work.<\/span><\/li>\n<\/ul>\n<\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Chloe: In the next section, the narrator talks about seeming like you know what you\u2019re doing but not actually knowing. This was the string theory section.<\/span>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Prof Littman: He talks about practical vs theoretical. The narrator\u2019s physicist father talks about the theoretical shoelace which if you pull hard on one side it tightens. The narrator talks about the practical side, which would hold that pulling hard would cause the shoelace to break.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Chloe: Would anyone like to explain String Theory<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Prof Littman: It\u2019s called String theory because it is a way to understand particles in the universe. Scientists imagine matter is made up of strings that have resonances. The concept is that particles in nature are made up of \u201charmonics\u201d like a string that is pulled. The big message in this section, however, has to do with the theoretical vs the practical. There is also another motorcycle term: gas shocks. A gas shock is a piston in a cylinder that is filled with air.\u00a0<\/span><\/li>\n<\/ul>\n<\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Chloe: The next section is called The Mentor and we meet a new hippy character named Chas who the narrator says introduces him to the \u201cpleasure of metal\u201d. It is quite a long chapter, but I wondered what you guys thought about the idea of metal as a complex theoretical material and about the idea of \u201cselling\u201d craftsmanship<\/span>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Ben: People wanting to buy cars or items understand that they spend more for better craftsmanship and more speed.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Prof Littman: Customers already know what they want, but maybe they need to be instructed to achieve it. Unrelated: I posted a resource about how head markings on bolts affect tensile strength and yield strength. The author also talks about ways of improving the engine on page 87.<\/span>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">He talks about tuning the engine to about 80 horsepower. What causes an engine stroke?<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Nate: the revolution of the crank would be the full stroke<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Prof Littman: If you wanted to increase the stroke, you would put the journal further away from the flywheel within the crankshaft<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Also Prof Littman: You also want air to come in and out of the engine at high speed.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Bill: A muffler is usually at the end of the exhaust pipe and it is a chamber that sound coming out of the exhaust pipe goes into so that when it comes out it is not as loud (it gets dissipated by physics in the muffler)<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Prof Littman: Yes, the muffler affects the rate at which air comes in and leaves from the engine, which itself affects the power of the engine. If you wanted a more powerful car you would remove the muffler to get better car breathing.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Eugene: why would you want a light and fast flywheel. Isn\u2019t the point of a flywheel to store energy so wouldn&#8217;t you want a lot of mass?<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Bill: If you are starting and stopping cars quickly for racing, you want a lighter flywheel so that the mass doesn\u2019t affect breaking as much.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Prof Littman: The author also shows an image of and talks about match boarding. What is that? It is when you make certain that going from one piece to another piece of the engine, it is a smooth and compatible connection (from tube to tube for example).<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Chloe: The next section talks about blueprinting an engine. I think this means identifying the wear and tear of an engine and making sure the parts you put into an engine are usable and strong. To get us started in this section, it is interesting that my perception of why wheels changed by working with the motorcycle wheels and thinking about their alignment.<\/span>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Bill: I teach a course on watercolor painting, and I go around and comment on other people\u2019s paintings. I usually tell people to go walk around the room and then come back to their painting to look at it again with a different perspective.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Aynslie: In flying, you have to put complete faith in your flying instruments to see the bigger picture and not freak out or just focus on one thing while flying.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Prof Littman: I was thinking of the drawing of the skeleton. There is an exercise in painting where beginner painters are made to paint a face right side up and upside down. It usually looks better starting upside down because in that case you are thinking about the relationship between lines and angles without bias of thinking you know what a face looks like.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Abby: We also drew a skeleton in my high school.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Prof Littman: This section also talks about patterns of wear and mushrooming in engine valves and stems<\/span><\/li>\n<\/ul>\n<\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Chloe: The next section is on personal knowledge.<\/span>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Nate: I really like the new definition and interpretation of what an \u201cidiot\u201d is. It talks about how mechanics who don\u2019t really care about their craft are idiots because they aren\u2019t embracing their public role.<\/span><\/li>\n<\/ul>\n<\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Chloe: The next section thinks about stopping to make sure you understand what problem you\u2019re solving before moving to actually solve the problem. It is the issue of metacognition.<\/span>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Emily: I think it was interesting to see the vulnerability involved in accepting you could be wrong in some way.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Chloe: Yes, I think this is something that I sometimes get stuck in, not wanting to admit a mistake. I like the way he framed this problem in honesty and humility.<\/span><\/li>\n<\/ul>\n<\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Chloe: Last section talks about how our perception of service workers as automated script readers should inform our decisions as consumers to seek out more authentic and dedicated service.<\/span>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Nate: I thought about this when I worked at a restaurant. It seemed like pushing people to follow a script undermined the intellectual integrity and expression of the service workers.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Bill: I\u2019m worried about this issue especially in the context of AI.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Prof Littman: Yes, I also think an understanding of the big picture of systems and applications could also get lost in the context of AI, because AI just seems to care about the minutiae.<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">We also have to start to talk about the final presentation. Presentations should be group powerpoint presentations on small but interesting details of each motorcycle group.<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400\">4\/8 Discussion Notes<\/span><\/p>\n<p>&nbsp;<\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Class introductions to Professor Martinelli (guest speaker today)<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Prof Martinelli \u2013 originally from Rome, Italy \u2013 came to Princeton for grad school, never left (began teaching here), is an expert in fluid mechanics and locomotion<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">His talk:<\/span>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Computational fluid mechanics is at the intersection of engineering and computational mathematics<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Fluids are usually opposing motion (Drag force)<\/span>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">A fluid flow goes from a laminar (organized) motion to a more disturbed and chaotic motion after coming into contact with an object in motion<\/span><\/li>\n<\/ul>\n<\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Lift (force)<\/span>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Keeps airplane in the air \u2013 generate lift by making use of fluid flow on the wing surface<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Flow field behind the wing of an airplane is very messy (turbulent regime of fluid flow)<\/span>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Lift is generated by the most turbulent, tornado-like fluid flow on the wings<\/span>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">This also generates drag<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Professor Littman query \u2013 it is often taught that lift is generated by suction<\/span>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Prof Martinelli says this explanation is not actually true<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">The control volume approach (that Prof Littman tends to use) is in the long-run accurate, but the more correct explanation comes from the vortexes of fluid generating lift by spinning in a certain direction<\/span><\/li>\n<\/ul>\n<\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Other question about aspect ratio<\/span>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Aspect ratio is fixed as a function of how the airplane is made \u2013 need stronger engine to overcome induced drag which is inevitable<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Reynolds number<\/span>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">As you increase the Reynolds number, the drag in the wake of an object in motion becomes a far more turbulent regime and the drag\u2019s diameter decreases<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Adding dimples to a golf ball for example accelerates the process of increasing friction drag, creating more turbulence in the wake, and having the induced drag go down<\/span><\/li>\n<\/ul>\n<\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">In supersonic or subsonic speed fighter jets, the plane wings must be narrow to stay within the shock angle \u2013 less lift so stronger engines<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Acoustic Field<\/span>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Lots of interaction between the fluid dynamic structure and the acoustic field that is generated<\/span>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Speech is the result of a very very small pressure disturbance that the listener detects and can decode as language<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Integrated resistance &#8211;
