style=\"font-weight: 400\">Make sure to use the same standard to not round out the hardware<\/span>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Several tools, such as wrenches, may appear to be the same size and may fit a certain nut, but is not necessarily meant to be used<\/span><\/li>\n<\/ul>\n<\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">There are both Imperial and Metric standards for tools, and so in the lab, you may see both standards<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">If correct measurements and standards are maintained then the hardware can be weakened.<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p><span style=\"font-weight: 400\">Learning Objectives<\/span><\/p>\n<ul>\n<li

style=\"font-weight: 400\">Learn to use tools in a lab scenario<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Engine design, in this case, would specifically be compact engines in motorcycles<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Identify how philosophy and motorcycle design could intersect<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">To better understand the terminology in the design process: EX: carburetor\/ carburation<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">The evolution of motorcycle design and how motorcycles have changed over the years<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Exploring the part of the whole motorcycle, the purpose for each part, and identifying where each part belongs in the system<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Identifying the parts in a system and how the individual systems operate between one another<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400\">Read the introduction to Zen, which is chapter one<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">This will be discussed in class on Wednesday<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Do not get the bootlegged versions of the book<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">The first chapter is posted on canvas<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400\">As for riding the motorcycle<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">After completion, the students can ride the motorcycle assuming their license permits them to.<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400\">Wednesday\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">Discussion leader- Celia<\/span><\/p>\n<p><span style=\"font-weight: 400\">There remains a sense that there is no one in the book knows where the group is going<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Some clues hint that Chris may indeed know<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">The book is shown through a first-person perspective, from the narrator<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400\">Motorcycle metaphors<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">There was a scene where John and the rest were at a bar and John\u2019s motorcycle was not starting<\/span>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">They tried getting the motorcycle to turn on but it was choking and thus couldn\u2019t turn on<\/span>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">This happens when the valve allowing the air in the carburetor is blocked off, this explains why John smelt gasoline when he tried turning it on.<\/span><\/li>\n<\/ul>\n<\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Since the carburetor was choking due to the gasoline in the motorcycle, the motorcycle wouldn\u2019t turn on<\/span><\/li>\n<\/ul>\n<\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Page 14, where motorcycles have a more open design<\/span>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">This motivates people to work on their own motorcycles<\/span>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">This is opposed to how traditionally individuals may refer to a mechanic to fix their car<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p><span style=\"font-weight: 400\">Content of the Chapter<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">The chapter describes the group traveling along the roads with the narrator\u2019s son and couple<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">The group, especially the narrator, shows a preference for the sensory aspect of riding a motorcycle<\/span>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">The narrator describes the lack of a frame on a motorcycle, which makes him feel as though he is in the environment as opposed to merely viewing it<\/span>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">These ideas feel almost as if he was preaching this idea<\/span><\/li>\n<\/ul>\n<\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Riding rough terrain is also preferred because of the amount of connection they feel<\/span><\/li>\n<\/ul>\n<\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">John and the Narrator feel strongly about their own views on motorcycle maintenance<\/span>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">They both acknowledge one another and their viewpoints, but they still become extremely frustrated with one another<\/span><\/li>\n<\/ul>\n<\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">The whole book is an inquiry into values in regard to the philosophy of motorcycles and their relationship to the narrator<\/span><\/li>\n<\/ul>\n<p><strong>Aditi Notes for Monday 2\/5\/24<\/strong><\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Disassembling

wheel on the truing stand to check that it was working correctly. The front wheel was in good shape but the rear wheel had some waddling to it, the motion was side to side.<\/span><\/p>\n<p><b>Framework group<\/b><span style=\"font-weight: 400\"> &#8211; disassembled the forks with difficulty. For the first fork they grounded down the socket wrench then, holding the fork with the vice and the wrench with the vice grip, they were able to unscrew the first fork and extract the spring (suspension system). For the second fork, they tried this method to no avail so instead resorted to using a 5\/16ths socket and two adapters, with the help of Professor Littman, they were able to unscrew this fork by putting a socket and the adaptors (which we ground flat) into an impact driver and hitting the contraption into the restrictor rod using a mallet.<\/span><\/p>\n<p><b>Engine group<\/b><span style=\"font-weight: 400\"> &#8211; attempted to use electrolysis to polish the engine but the machinery in the labs was in use so they were unable to do this.

They also worked with the brake cable, adjusting it. Today they will work on the springs but they may have to put new springs on because the old ones were slightly too soft. Professor Littman has purchased new springs which may be a little too small but they are stiffer.<\/span><\/p>\n<p><span style=\"font-weight: 400\">During precept today, we spent some time looking at the workshop instruction manual for our Triumph Tiger Cub. Professor Littman drew a model of the sprockets and explained this to our class. We determined that the rear wheel is going about 15.5 revolutions per second when the engine is going 100 revolutions per second. We also determined that the top speed of the motorcycle is about 66 mph. During the next class, we will assess the torque required for the engine and the rear wheel as well as the tension on the chain.<\/span><\/p>\n<p><b>Reading:<\/b><\/p>\n<p><span style=\"font-weight: 400\">Chapters 12-15 in <\/span><i><span style=\"font-weight: 400\">Zen and the Art of Motorcycle Design<\/span><\/i><span style=\"font-weight: 400\"> (not many motorcycle references)<\/span><\/p>\n<p><b>Chapter 12<\/b><\/p>\n<p><span style=\"font-weight: 400\">Discussion led by: Hasan<\/span><\/p>\n<p><b>Motorcycle references<\/b><\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">None<\/span><\/li>\n<\/ul>\n<p><b>Content<\/b><\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Starting in Cooke City (after they have gone up to the high prairie), they finish this chapter in Gardiner, Montana.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Pg 135 \u201cChris seems to understand my remoteness better than they do\u2026\u201d suggests that the narrator relies on Chris to control and be cognisant of his emotions.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Pg 136 \u201cit\u2019s a problem of our time\u2026\u201d commenting on how people specialize in one thing but are not exposed to anything else.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Pg 137 \u201cremembers that Phaedrus had a high regard for DeWeese\u201d although neither one of them fully understood the other.

Today they will take care of the electrical system and fix the throttle cable as Professor Littman identified as faulty parts of the motorcycle.<\/span><\/p>\n<p><span style=\"font-weight: 400\">During precept today we revisited the workshop instruction manual for our Tiger Triumph Cub. This time we used the information to calculate the tension on the chain and the torque required in the engine. We determined that 5 ft lbs of torque are required in the engine to get the rear wheel to slip at the lowest gear. A higher gear would require more torque (Torque = r x f when they are at right angles to each other). The required tension on the chain is about 30#.\u00a0<\/span><\/p>\n<p><b>Reading:<\/b><\/p>\n<p><span style=\"font-weight: 400\">Chapters 15 &amp; 16 in <\/span><i><span style=\"font-weight: 400\">Zen and the Art of Motorcycle Design<\/span><\/i><\/p>\n<p><b>Chapter 15<\/b><\/p>\n<p><span style=\"font-weight: 400\">Discussion led by: Sarah<\/span><\/p>\n<p><b>Motorcycle references:<\/b><\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Pg 175 chain adjuster.\u00a0<\/span><\/li>\n<\/ul>\n<p><b>Content:<\/b><\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">John and Sylvia leave.

The book is the narrator\u2019s fictional travel log about his trip across the country.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Travel portion<\/span>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">End up in San Francisco.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">(Will) Left off when they were in Bend, and the narrator was lamenting being on the West Coast because everything moves so quick and seems so impersonal.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">(Littman) Head down the coast of California to San Francisco in the last leg of the journey. When they get to the more coastal, urban areas, people become less social and more to themselves.\u00a0<\/span><\/li>\n<\/ul>\n<\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Narrator\u2019s relationship with his son Chris<\/span>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">(Sarah) Chris is realizing that his relationship with his father is changing. Starts crying a bit more, has a breakdown.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">(Gabrielle) Chris has more and more meltdowns until the narrator sends him home to protect himself and Chris. Chris doesn\u2019t want to leave and the narrator realizes that Chris is similar to Phaedrus and might on the trajectory to become him.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">(Littman) The Narrator\u2019s dream about Phaedrus starts the tension between Chris and the narrator. The narrator makes the decision to send Chris back on the bus, but doesn\u2019t tell him until much later thinking Chris will be relieved. Instead, Chris has a breakdown. As Phaedrus comes out more and more, Chris seems relieved. Chris realizes his father is a \u2018fake\u2019 and that they don\u2019t have a \u2018quality\u2019 relationship. The book ends with the narrator turning into Phaedrus and Chris seems, again, relieved, breaking the tension.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">(Sarah) We only get the perspective of the narrator, which shifts our perspective on the book.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">(Littman) The narrator was not really living a quality life.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">(Bryan) The narrator early on is fairly cowardly, never accepting or engaging with Phadrus thoughts of quality (dream also shows this).\u00a0<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">(Sarah) A small moment where they are on the road and it\u2019s raining, and the narrator puts the blinder down (for the rain), but decides he doesn\u2019t like it, raising it. Chris stands up and says that he can finally see.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">(Littman) Metaphorical that Chris is no longer in his father\u2019s shadow but stands up and can see past his shoulders?<\/span><\/li>\n<\/ul>\n<\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Philosophy<\/span>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">(Sarah) Learns about philosophy at University of Chicago.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">(Littman) The Narrator gets into University of Chicago through a trick and gets on the Committee of Analysis of Ideas and Study of Methods (does not get into the Philosophy department). Wants to argue with Plato, Socrates, and Aristotle. Narrator tries to work out why Plato, Socrates and Aristotle did not think that rhetoric and the arts were not as important as science and reason. A soul is like quality in the narrator&#8217;s mind. Socrates says a person seeking truth is in a \u201cchariot\u201d and there are two horses pulling him along: a black horse that is passionate and keeps getting in the way of the chariot, and a white horse that is reason. The narrator reflects on his interaction with a professor where he disagreed with this story, and \u2018outwitted\u2019 the professor. However the narrator feels criticized, which makes him depressed and subsequently insane.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">(Littman) Mythos is the older Greek stories &#8211; myths. Logos are the newer Greek stories rooted in logic and reason.\u00a0<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400\">See Zen and Art of Motorcycle Maintenance page on website for summary\/important parts of each chapter.\u00a0<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400\">The next book, Shop Class as Soulcraft, has a lot of motorcycle references.

On your engine, probably not that important. But if you want to increase the fuel efficiency, you want to have a rich charge at the beginning for ignition, and then a lean charge when the temperature is high so you burn less fuel. In this case, you need to get a swirl on the cylinder, the shape of the piston is very important.<\/span><\/li>\n<\/ul>\n<\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Q: Shape of our motorcycle affecting its aerodynamics?<\/span>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">A: It\u2019s pretty lousy, not a streamline, which creates a lot of drag. Compute the frontal area with the rider and use some formula related to turbulent weight, and then you can estimate drag. Most of the drag is going to be affected by the frontal area and the person riding it.<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<hr \/>\n<p><strong>Ryan Brunswick 4\/8 &amp; 4\/10 Notes<\/strong><\/p>\n<p><strong>4\/8 Notes &#8211; Guest Speaker: Bill Becker\u00a0<\/strong><\/p>\n<p><span style=\"font-weight: 400\">Evolution of the Motorcycle Wheel<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">1790 first wooden prototype<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">1885 first motorcycle with motor<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">1895 spoked wheel with metal rim and hub\u00a0<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">1960 Modernized motorcycle design\/front wheel spokes and rear wheel used cast<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Todays using wheels with magnesium or even aluminum\u00a0<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400\">Major wheel design influences\u00a0<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Weight<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Speed\/efficiency<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Technological advancement and industrial revolution\u00a0<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400\">Material property considerations\u00a0<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Strength\u00a0<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Flexibility\u00a0<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Cost\u00a0<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Conductivity\u00a0<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400\">Rim and spokes made out of steel for our wheel. <\/span><span style=\"font-weight: 400\">Best Performance at the lowest cost = efficiency\u00a0<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400\">Dead Load = Motorcycle weight itself\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">Live Load = Additional weight like passengers\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">Static Load = Wheel at rest\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">Dynamic Load = Wheel in motion\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">Acceleration of back wheel (Rotary torque), applying break, turning the motorcycle, colliding with an object or maybe a curve. <\/span><\/p>\n<p><span style=\"font-weight: 400\">Spokes divided into groups of 4. 40 for British wheel. 4 spokes in a cluster because. <\/span><span style=\"font-weight: 400\">One to transfer energy from hub to rim.

They did a wring twist and trying to make it right.<\/p>\n<p style=\"font-weight: 400\">Troubleshooting: electrical system, mapping out how to route it thorough the system. carburetor and getting the screws right.<\/p>\n<p style=\"font-weight: 400\">Guest:<\/p>\n<p style=\"font-weight: 400\">Professor Ju, MAE department. Research area is in combustion and propulsion. Working with NASA on propulsion system. using renewable electricity to do manufactured materials, ammonia, and hydrogen. Leading DOE energy earth shot. Teaching rockets and hydrogen propulsion for rockets.<\/p>\n<p style=\"font-weight: 400\">Ignition. Light too early, high early combustion, longer resin time in the engine. NOx: nitrogen in high temperature, nitrogen reacts with oxygen to create NOx, NOx. Created acid rain. PH values of swimming pools. Causing human health issues.<\/p>\n<p style=\"font-weight: 400\">\u00a0It has to be regulated from all propulsion aircrafts. From 1990, car companies have to sacrifice efficiency to regulate NOx emission. The higher the temperature, the higher the NOx. Ignition earlier, you are causing the engine to knock. Two things which make you want to delay the ignition. Less time for engine knock.<\/p>\n<p style=\"font-weight: 400\">If you go to the pump station, you have to choose an octane number. It is the engine running of fuel. They have a standard test engine, putting the fuel and running the engine. In a gas engine you suck the air and keep the fuel, you have a spark. The speed of a flame is less thana. Meter per second. The engine consumes the fuel in 10 milliseconds. Knock means the mixture is so reactive that the rest of the fuel starts to auto-ignite. Once the flame ignites by itself, the speed of ignition rises and can cause detonation. The detonation can be 50x higher. It could destroy the engine right away.<\/p>\n<p style=\"font-weight: 400\">To prevent this, you use octane number. The higher, the more anti-knock. The fuel allows you to operate at a higher pressure more efficiently. Engine temperature is important to. The hotter the engine the higher the knock.<\/p>\n<p style=\"font-weight: 400\">Diesel engine doesn\u2019t have a spark, they auto-ignite.<\/p>\n<p style=\"font-weight: 400\">Octane measure is real fuel, if you have 100% octane, octane is 100. It will be less resistant to knock. Alcohol octane number is close to 110. 110 happens when you increase the pressure needed for a knock.<\/p>\n<p style=\"font-weight: 400\">Alcohol has high octane numbers; inner density is lower.<\/p>\n<p style=\"font-weight: 400\">High pressure=higher efficiency. Same with rockets.<\/p>\n<p style=\"font-weight: 400\">The highest temperature normalized by the lowest temperature. Lowest temperature is the. Environmental temperature. Making the temperature higher.<\/p>\n<p style=\"font-weight: 400\">In the world there is big emphasis on decarbonization. Using battery to prevent this. In the near future this will happened. How do we reduce the energy sectors in manufacturing.<\/p>\n<p style=\"font-weight: 400\">In China, EVs occupy 50% of new car sales in China. Less than 10% in the US.<\/p>\n<p style=\"font-weight: 400\">China, 10 years ago wanted to shortcut the route to EVs. For that to happen. They need two things.\u00a0 Price has to be low. Electricity has to be cheaper. China\u2019s coal powerplant increased dramatically, to make energy cheap. China is both helping and hurting the climate issue. Every two weeks China builds a new coal mine.<\/p>\n<p style=\"font-weight: 400\">In the US if you increase dramatically renewable electricity, you cannot use batteries to stop it. You cannot pump water to the reservoir. You use peak hours of fluctuating electricity. For 10 years it will still be there. For large scale energy stories,<\/p>\n<p style=\"font-weight: 400\">Milai cars in Japan. Have a hydrogen gas tank in the car.<\/p>\n<p style=\"font-weight: 400\">If you compress hydrogen into 200 bars for cars to use, you lose 15% of efficiency to use it.<\/p>\n<p style=\"font-weight: 400\">Transportation, safety, and density make hydrogen not a great choice for somewhere like Japan.<\/p>\n<p style=\"font-weight: 400\">Liquid ammonia; much higher density compared to hydrogen. Don\u2019t worry about the burning. Transportation, safety etc. problem with ammonia is if you burn it, it takes thousands of ppm of NOx. You\u2019re creating thousands of PPMs.<\/p>\n<p style=\"font-weight: 400\">Gas turbines: jet engine.<\/p>\n<p style=\"font-weight: 400\">Princeton have two gas turbine engines. They can be up to 30% efficient.<\/p>\n<p style=\"font-weight: 400\">Combined cycle is very preferable.<\/p>\n<p style=\"font-weight: 400\">In 20 years\u2019 time:<\/p>\n<p style=\"font-weight: 400\">Batteries will be widespread.<\/p>\n<p style=\"font-weight: 400\">Hydrogen will be the clean energy generator. You can clearly change it.<\/p>\n<p style=\"font-weight: 400\">Green, blue, and dark hydrogen. Dark hydrogen from natural gas. Green hydrogen is from electrolysis. Blue hydrogen is electrified paralysis of methane from hydrogen and carbon.<\/p>\n<p style=\"font-weight: 400\">AI; and driverless cars are going to be the future.<\/p>\n<p style=\"font-weight: 400\">Africa and. Asia. Africa and Asia are incomparable in terms of size.<\/p>\n<p style=\"font-weight: 400\">For KSA in the next 20 years, oil will still be around. In the long term, these countries will move on to nuclear energy, etc.<\/p>\n<p style=\"font-weight: 400\">The government of Saudi should look at green energy.<\/p>\n<p style=\"font-weight: 400\">Marine engines and ammonia.<\/p>\n<p style=\"font-weight: 400\">You create enormous amounts of N20, it\u2019s a two or four stroke engine. They continue on one engine. If you have CO2\/hydrogen. Burn alcohol it\u2019s much better than ammonia.<\/p>\n<p style=\"font-weight: 400\">Guest left.<\/p>\n<p style=\"font-weight: 400\">Presentation on the 6<sup>th<\/sup>. Reading on Monday. Next week Ch.8 and the afterword.<\/p>\n<p><strong>April 17 notes:<\/strong><\/p>\n<p>Fahd bin Faisal<\/p>\n<p style=\"font-weight: 400\">Cap screws:<\/p>\n<p style=\"font-weight: 400\">Top ones for US bolts.<\/p>\n<p style=\"font-weight: 400\">No markings.<\/p>\n<p style=\"font-weight: 400\">3 radial lines.<\/p>\n<p style=\"font-weight: 400\">6 radial lines.<\/p>\n<p style=\"font-weight: 400\">The bolts would look identical. But the yield strength differs. More markings, more yield strength.<\/p>\n<p style=\"font-weight: 400\">Readings:<\/p>\n<p style=\"font-weight: 400\">Chapter 6:<\/p>\n<p style=\"font-weight: 400\">Contradictions of a cubicle:<\/p>\n<p style=\"font-weight: 400\">Dilbert cartoons: engineer in a cubicle.<\/p>\n<p style=\"font-weight: 400\">The point made in the beginning is: results-based and performance-orienting. That is very easy to say, but you are not really producing anything either.<\/p>\n<p style=\"font-weight: 400\">\u201cproduction of goods instead of production of brands\u201d<\/p>\n<p style=\"font-weight: 400\">Indexing and abstracting:<\/p>\n<p style=\"font-weight: 400\">Ziff-Davis company: still exist. Book isn\u2019t sure whether they are still around, but they are.<\/p>\n<p style=\"font-weight: 400\">He got hired for the job because he had a masters. He was being paid more. His job was to read a paper, and then rewrite the abstract. He thought it to be quite dumb. Supposedly writing an abstract for nothing he knows about.<\/p>\n<p style=\"font-weight: 400\">His credentials got him the position, but he isn\u2019t confident in it.<\/p>\n<p style=\"font-weight: 400\">Interaction with his supervisor: she critiques his work; she had his job previously. When she is critical, she pays specific focus on the grammar and not the content. The company isn\u2019t doing anything worthwhile, they\u2019re just in business.<\/p>\n<p style=\"font-weight: 400\">Issues of credentials:<\/p>\n<p style=\"font-weight: 400\">How important credentials are to a job.<\/p>\n<p style=\"font-weight: 400\">Soft skills are more important than learning a trade in this world.<\/p>\n<p style=\"font-weight: 400\">Recruiters saying that your grades don\u2019t matter. You\u2019ve shown a display of \u201cmiddle class self-discipline\u201d in that you can do disciplined study of a specific field.<\/p>\n<p style=\"font-weight: 400\">Ranking has some effect on graduate school.<\/p>\n<p style=\"font-weight: 400\">Teamwork-pull getting people to work together. The ego-breaking attitude.<\/p>\n<p style=\"font-weight: 400\">The crew vs the team.<\/p>\n<p style=\"font-weight: 400\">How do you figure out whether you\u2019re doing a good job?<\/p>\n<p style=\"font-weight: 400\">Individual agency and through it figuring out if you\u2019re doing a good job.<\/p>\n<p style=\"font-weight: 400\">Through good organization and insight, you can balance and improve individual output.<\/p>\n<p style=\"font-weight: 400\">Steve Jobs at Apple-left and Apple did poorly. Comes back and turns it back around. The metric here is how well the whole company is doing.<\/p>\n<p style=\"font-weight: 400\">Chapter 7:<\/p>\n<p style=\"font-weight: 400\">Thinking as doing:<\/p>\n<p style=\"font-weight: 400\">Education nowadays focuses in knowing why and not how. People don\u2019t know how to perform tasks, but just know the ways of doing it.<\/p>\n<p style=\"font-weight: 400\">Knowing how is more important than knowing why.<\/p>\n<p style=\"font-weight: 400\">People have a know-how of a particular system. they know how to operate but know how to improve upon. Other people can make radical improvements that knob-twiddlers won\u2019t be able to do.<\/p>\n<p style=\"font-weight: 400\">People who work on electrical systems know that thy need to make their work tight, dry, and clean.<\/p>\n<p style=\"font-weight: 400\">Ohms law: relationship between voltage\/current and resistance.<\/p>\n<p style=\"font-weight: 400\">Story of fixing an electrical system that isn\u2019t working. It\u2019s a wet day, so he brings out a WD40, a water displacement, it replaces the water with the surface of oil. If something\u2019s wet, you spray it with WD40. If it\u2019s a sandy day, you can use an air hose instead of the WD40.<\/p>\n<p style=\"font-weight: 400\">Tasset knowledge of the firefighter and chess master.<\/p>\n<p style=\"font-weight: 400\">Formulaic thinking, how some people tend to think in patterns. You start with the example of firefighters. Also talks about the IBM\u2019s deep blue. Also, the ultimate chess master in 97. Ability to predict move and see patterns. Mechanics see patterns from prior experiences.<\/p>\n<p style=\"font-weight: 400\">Training sets are what these neural networks do. Through the patterns they give you an answer.<\/p>\n<p style=\"font-weight: 400\">Neural networks are nothing but pattern recognizers.<\/p>\n<p style=\"font-weight: 400\">A mechanic figures out connections, without really understanding what\u2019s going on underneath.<\/p>\n<p style=\"font-weight: 400\">Chapter 8 and concluding remarks next week.
