Human: what engineering jobs require the most physics and high level math? Assistant: Software Engineer for ANSYS lol	Human: what engineering jobs require the most physics and high level math? Assistant: R&D, simulation, control systems that interact with the real world.
Human: If there were a consumer car that was designed to drive for 1,000,000 miles...what would be different relative to cars we get now? I understand we can buy a car that turns over a million miles. I also understand that diesels like the long haul rigs are meant to just dump miles on miles on miles. I'm more wondering what would be different about something like a Toyota Camry if they designed it to hit 1,000,000 miles with nothing but fluid changes and brakes vs sedans we can get right now. So more specifically; engine and since I live in the rust belt...Rust prevention/negation. Assistant: Replacing rock salt with road pepper should do the trick 👍	Human: If there were a consumer car that was designed to drive for 1,000,000 miles...what would be different relative to cars we get now?

So more specifically; engine and since I live in the rust belt...Rust prevention/negation. Assistant: Electric but reasonably powered and batteries would be conservatively managed to maximize range, as well as order of magnitude higher QA process to ensure maximum quality cells are in the vehicles.
Human: I am correct in understanding that it would be practically impossible to get a job if I had a 6-9 year gap after graduation? Would there be literally no options or would there even be a slight chance that I could get hired? Assistant: Jesus OP answer some of these questions so you can at least get a reasonable answer. You gave far to little detail.	Human: I am correct in understanding that it would be practically impossible to get a job if I had a 6-9 year gap after graduation? Would there be literally no options or would there even be a slight chance that I could get hired? Assistant: Consider starting with recruiters. HR likes to shit their pants over what they call “redflags”
Human: Does previous non-engineering work experience matter when looking for an engineering internship? When I apply for internships, will having previous non-engineering related work experience (jobs such as food service or working a student job for your university) help or will possible employers not really care? Assistant: Hiring manager here. Add it as a line, but don’t go into detail. I’d like to know you can hold a job down and be responsible, but I don’t really care what you did at Starbucks. Excluding it makes me question how reliable you’d be, akin to when I got stuck with a VPs privileged kid who never worked a day in his life, who would up rolling in at 10am every day, sleeping in the bathroom, and sneaking out by 2pm when I was in my afternoon meetings.	Human: Does previous non-engineering work experience matter when looking for an engineering internship? When I apply for internships, will having previous non-engineering related work experience (jobs such as food service or working a student job for your university) help or will possible employers not really care? Assistant: If you don't have relevant experience, then show what you have. It'll at least let me as a hiring manager know that this isn't going to be your first time in a workplace or professional setting and I'm going to have to teach you the very basics of professionalism.
Human: Non-American engineers, how often do you have to deal with Imperial Units and how often does it complicate things? Assistant: Norway checking in. Not very often, except for pipes, valves, fitting and other pipe related items, which for some reason is either in inches or some weird metric measurement which is obviously a converted imperial measurement. When I do have to deal with it, it’s allways very annoying. And if we get into the 5000 different types of «tons», I flip my desk...	Human: Non-American engineers, how often do you have to deal with Imperial Units and how often does it complicate things? Assistant: Based in Norway. The company I work for never use Imperial for anything engineering related but we do convert to imperial units after the fact when shipping products to the US. Imperial units for radioactivity is tied directly to laws and regulations so we are pretty much required to use the same units.
Human: What would be a good substitute for sputtering of metal layers Atomic layer deposition sounds like a good idea to deposit layers between 10-200 nm but i was wondering if thermal evaporation would also be a good alternative? Assistant: What about simple electroplating? What metal are you depositing and what are you depositing on? Even if it's non-conductive, there are ways of making it conductive: https://www.youtube.com/watch?v=nGmxHLHyUPc	Human: What would be a good substitute for sputtering of metal layers Atomic layer deposition sounds like a good idea to deposit layers between 10-200 nm but i was wondering if thermal evaporation would also be a good alternative? Assistant: What is the use case? Environment? Budget? etc?
Human: Does anybody else wish they were paid hourly? Work in manufacturing (salaried), and just did the math - if I were paid entry-level operator wages (including 1.5x OT for >40 hr/wk), for the hours I worked last year, I would have made a whopping $1,478 less than I did. Unrelated, is anybody hiring WFH data analysts? Assistant: No? I work 40hrs a week, just like my contract states im paid for. If i stay late, i come in late next day. If i work Saturday, I don't come in monday. If you are working more than your contract dictates you be compensated for, you need to stop devaluing our profession. Demand to get paid for the hours you work, or stop working them.	Human: Does anybody else wish they were paid hourly?

Unrelated, is anybody hiring WFH data analysts? Assistant: Yeah, don’t average over 40.
Human: has anyone here earned a PhD that was paid for by their company? how did you go about applying for it? Assistant: Government but they are happy to fund grad degrees. At PhD you need a head science official to sign off classes. Once you're in they have programs that will let you take time off work to focus on the research	Human: has anyone here earned a PhD that was paid for by their company? how did you go about applying for it? Assistant: I had a chap working in my team who got his PhD like this. Basically the research he was doing was relevant to the work and was sponsored by us.
Human: What do you think of engineering/science that is the closest to magic? I'm trying to determine what is the most unexplainable, confusing pheneomons out there that we know of yet are unexplainable in the fields of engineering/science. What is the most shrouded in mysteries waiting to be discovered or realized. Stuff like that. I've read around a bit and I'm thinking along the lines of magnets, radios, electricity, etc. Or space and astronomy. Or Maybe the ocean and what lives under it. AI? Biotechnology? Biochemistry? Psychology or neuroscience? Thereotical mathematics? There's so much! Bonus: What field of study is it under? Trying to determine what to study. Assistant: Q-bits and quantum computing. That's shits nuts.	Human: What do you think of engineering/science that is the closest to magic?

Human: What's your least favorite part of your job? Assistant: The physical office environment. Background noise, HVAC settings, chair/desk, lighting, smells, etc. I have no control over it and my home office is better in just about every way.	Human: What's your least favorite part of your job? Assistant: IT. Everything has to get approved by IT and they hold up our projects moving forward because they operate on their own schedule. But god forbid you don’t give them what they want in a timely manner.
Human: Your stories about excellent technical engineers who were "forced" to become leaders? Maybe it was you or maybe someone you work with or someone you promoted as a leader yourself. Do you have any stories about excellent technical engineers who were "forced" to become leaders? As an example, let's say one engineer is an average communicator but excellent technically, the other engineer is an excellent communicator but average technically. Often times, the excellent communicator but average technical engineer asks to become manager or leader, while the average communicator but excellent technical engineer stays silent. You chose the technically excellent but average communicator engineer to become the leader; did that turn out to be a good decision? What were the plusses and minuses? Any interesting stories? Assistant: I don't know if I'd call myself an excellent engineer but I was recently promoted and I'm doing terribly. A few months ago my boss called me into his office and basically told me that I was being promoted to team lead whether I liked it or not. I have absolutely no idea what I'm supposed to do all day. One of the project managers is sort of covering for me but I'm probably going to get let go soon. Almost 15 years as an individual contributor and I've never felt less effective.

Assistant: My department director was a shitty scientist and even worse people manager.
Human: What engineering jobs / industries can an incompetent engineer work in for many years with a low risk of getting fired? I see government jobs high up on list ( hard to get into and even harder to get fired from) but I do not know why this is the case. Competitive companies such Pfizer, google , and ExxonMobil typically want the best of the best , so I could imagine that weak engineers get weeded out relatively quickly.

Human: What are the most important transferable skills an Engineering graduate of the future will need? In your opinion what do you think are the most important transferable skills for a new graduate engineer to hold. This can be technical skills or emotional skills? Assistant: Understanding the big picture. My young engineers will spend 8 hours designing a new part but never questioned if a new part was necessary. They rarely think to ask about the business case. Who is the customer? How many are they buying? What's the risk if we build/ship this and something goes wrong?	Human: What are the most important transferable skills an Engineering graduate of the future will need? In your opinion what do you think are the most important transferable skills for a new graduate engineer to hold. This can be technical skills or emotional skills? Assistant: Talk to people
Human: Any general tips or advice for dating an engineer? This seems like an appropriate place to ask :D Serious answers appreciated but Jokes are also welcome :P Assistant: Engineers are people too. #engineerlivesmatter	Human: Any general tips or advice for dating an engineer? This seems like an appropriate place to ask :D Serious answers appreciated but Jokes are also welcome :P Assistant: Grease their joints and charge their batteries frequently.
Human: Do Engineers in the US actually use MatLab on a regular basis? I’m a Biomedical Engineering major in my 3rd year, and I’m getting really sick of having to use MATLab for things that I could do far easier on Excel or Python. I know it’s useful and all, but my university likes to tell us that it’s an industry standard and that engineers use it all the time. Is this true? Assistant: I will get downvoted for this but I think/hope that Matlab is on its way out. Python is increasing in popularity and capability, and open source in general seems like a very natural way for engineers.	Human: Do Engineers in the US actually use MatLab on a regular basis?

Human: Engineering has often been potrayed as nerdy. In what I observed, this has changed over the last decade or so. Have you noticed this trend as well both in general and on the workfloor? For example, by seeing a lot more would be business majors entering engineering for the money? Assistant: I don't think this is a fair assessment. I've witnessed a mix, the nerds who know every fact about nothing, the jocks who can't take being wrong, the normal who just like things, it's a mixture. I've even seen all three on one person. What you see in the media is just a stereotype.	Human: Engineering has often been potrayed as nerdy. In what I observed, this has changed over the last decade or so.

Human: Engineers working full time, how do you motivate yourself to develop your skills during your free time? Hey guys. I'm 4 months into my first job after graduating. It's not something I'm interested in at all but I'd been searching for months and was grateful to get a job related to my degree (ME) even though the offer wasn't great at all. Now the issue is that I want to move to another industry, and that requires me to pick up some new skills, but can't seem to get started at all. My job is 8-5 with about an hour of commuting each way, so by the time I get back home and make something to eat I have a couple of hours before I go to sleep. I tried getting started one night but it seemed like my brain was extremely slow at picking up what I was looking at. I have no idea what to do, so any advice would be greatly appreciated. Thanks!

Human: Why is Saudi Arabia's 'The Line' a line? Is there any actual engineering or logistics reason that this megastructure is planned to be so long rather than a broader, shorter design, or even circular? It seems like it would be a logistical nightmare for construction and transportation. Also I can only assume there will be very minimal natural light at the ground floor in the centre of the two walls. Have they mentioned any solutions for this? Assistant: It's really stupid to make it 0.2 km wide and 170 km long. It has an area of 34 km^2. If it is built in a circle then the farthest apart anything could be would be 3.29 km. Instead the farthest distance anything could be is 170 km. Am I missing anything here? Is there something that makes this a good idea? edit. Correction. The farthest apart anything would be is 6.58 km. 3.29 km is the radius of the circle, not the diameter.	Human: Why is Saudi Arabia's 'The Line' a line?

Also I can only assume there will be very minimal natural light at the ground floor in the centre of the two walls. Have they mentioned any solutions for this? Assistant: It’s 100% not from an engineering standpoint because the external heat load of such a building is going to be huge since it’s got such a huge surface area in an extremely hot and sunny climate
Human: [Energy Management] In winter climates, what is the solution for how to electrify building heating without breaking the bank? Assistant: Insulation.	Human: [Energy Management] In winter climates, what is the solution for how to electrify building heating without breaking the bank? Assistant: Breaking the bank for the heating or the unit? Because by far the best electric heater is a heat pump. The ROI is only a few years as opposed to the cheaper but way less efficient electric resistive heating.
Human: What's the most ferromagnetic powder I can easily buy? I'm looking for powder as strongly attracted to a magnet as possible. I have some black iron oxide, and its' okay, maybe powdered iron would be better. There's NdFeB fro pretty cheap on Alibaba. For some reason I'm finding it difficult to get any numbers on and of these products, do I just have to buy a bunch and test them? Thanks for any advice! Assistant: Keep safe ! Powder can be really dangerous.	Human: What's the most ferromagnetic powder I can easily buy? I'm looking for powder as strongly attracted to a magnet as possible.

Assistant: NdFeB powder from China is pretty solid stuff (the only country that make it atm) it’s pretty exothermically reactive with oxygen unless it’s been treated with a phosphating process or some other conversion coating. It’s going to have the strongest magnetic performance though
Human: Is it normal to ask for a raise after my 90 day evaluation? Basically, I'm hella underpaid (65K), especially since I live in San Diego, CA. Granted, I got about 1 year of total engineering experience and I'm just trying to shoot for 80-90 a year. I'm doing Machine Vision Applications Engineering right now with this company. I've done everything they've asked so far so I feel like I got a good chance, just wanted to hear any tips on this subject from my fellow engineer.

Human: I'm a Math major and my friend is an Engineering major, and he is tormenting me with things like "sin(θ) = θ" and "e is basically pi which is basically 4". What sorts of things could I respond with that would make an engineer cry in the same way? Assistant: "you're an engineer? What kind of train do you drive?"

Human: Satcube has an 8 kg non parabolic antenna for satellite internet. I want to bring multi gigabit low latency internet to a <3 kg unit with low rain fade, low power use, backpackers can carry, and is easy to deploy. Based on my new and additional details and questions, what's your feedback? Background I want to bring multi gigabit satellite internet access to: * People living in and visiting areas only accessible by air taxi. This includes northern Alaska. * Indigenous people in less developed regions. * Low budget crews traveling to less developed areas to help the less fortunate * Backpackers, long distance travelers over non motor watercraft, mountain climbers, etc. * Scientists and tourists going to the north or south pole. * Disaster hit areas * Areas where electricity access is limited or not there. This is so low budget people described above can: * Provide literacy to remote, less developed areas. * Post and blog using recorded or real time video. This may include natural events of beauty like the aurora. * Have reliable internet even during heavy rainstorms in a forest. * Live over the internet video broadcast in 8K. Use of LongGOP VVC, 60 fps, 10 bits per channel, HLG HDR, and 4:4:4 chroma subsampling will be potential options. I eventually want to up it to 8K/16K with 3D light field support. This is to have true 3D for end viewers without headsets or special glasses. Ideas 1. Use satellites 500 km away. 2. If one antenna does not provide enough throughput, allow antenna bonding. It can be configured like a mesh network or use regular connection bonding. 3. Hot swappable power sources. 4. Use either: 1. The Ku band if there's a way to get 2 GHz of spectrum up and down. FDD is a given. 2. 4-4.18 GHz for the downlink and 5.925-6.105 for uplink only if steps are taken to prevent 6GHz WiFi interference. 3. 2.52-2.67 GHz combined with 4-4.18 GHz for downlink and 5.925-6.255 GHz for uplink. Same precautions needed. 5. A QAM level of 256 or higher. A higher level than 256 will be needed if less spectrum is used. 6. OFDM 7. Phased array antennas. 8. Intersatellite communications 9. Service sold on a wholesale basis and/or maybe first party basis. This is to allow creative but useful business models. 10. Network operators can use our gateway stations for their own networks. This is in addition to our own gateway integration. 11. Use either OFDMA or Sparse Code Multiple Access (SCMA) Questions 1. I know parabolic antennas for satellite communications get larger with wavelength. Is it the same for flat phased array antennas? 2. Is OFDMA or SCMA better? 3. In theory, which of the three frequency band ideas will strike a balance between antenna size, throughput, reducing power consumption, and resistance to rain fade? 4. If it's better to make small high throughput antennas for already developing Low Earth Orbit projects, what can be done to ensure: 1. The antenna can fit in a backpacking backpack. 2. Has 1+ Gbps throughput up and down. This is for 8K/16K light field video streaming. 3. Resistance to rain fade. 5. What's your advice? Assistant: I think you are crazy. Starlink is the closest but it is only ~100Mb/s, uses several hundred watts and could be used in a RV for example, but is not small enough for backpacking.

Human: hey guys, whats the best CAD Software for models with alot more than 10000 parts? currently using inventor... Assistant: Something that will help get you by if you still need to use inventor is to split your assembly into suitable sub assemblies if you haven't already and "append" them to a navisworks model. Just work on your sub assemblies in INV and visualize the whole assembly in Navisworks alongside it. You will have to manually hit "refresh" to see your changes but it might help you out a bit in the meantime.	Human: hey guys, whats the best CAD Software for models with alot more than 10000 parts? currently using inventor... Assistant: Decent strategy, price out NX and Catia then you should be able to justify hardware upgrades instead.
Human: If the engines in cars waste 70% of energy as heat, why don’t we reclaim that? This may be a stupid question, but couldn’t we use thermoelectric generators to reclaim some of this lost energy? Assistant: Low latent heat is difficult to recover efficiently. It’s why sterling engines aren’t used much.	Human: If the engines in cars waste 70% of energy as heat, why don’t we reclaim that? This may be a stupid question, but couldn’t we use thermoelectric generators to reclaim some of this lost energy? Assistant: I know BMW tried years ago but not sure what happened to the idea as it disappeared without trace. Probably negligible gains compared to the extra weight\cost etc. Edit: Found it: BMW TurboSteamer
Human: What thing you dreamed of inventing as a kid but soon realized it wasn't feasible as an adult? Assistant: Electric cars but not using batteries, but instead using extension cords overhead. Basically a massive network of extension cords to power our vehicles lol	Human: What thing you dreamed of inventing as a kid but soon realized it wasn't feasible as an adult? Assistant: As a kid I thought rust was like, something that formed on a surface… like a mold or fungus. So I wondered why proper didn’t create like… rust removal tape to just peel it right off and have pristine metal underneath
Human: Why Is It Impossible to Get An Engineering Job These Days? Honestly, I am curious if companies are just hiring people with 5+ years of experience for an entry level position that is meant for a new grad because they can get it considering all the people who are laid off due to pandemic. Assistant: No. My company is desperately trying to hire engineers right now	Human: Why Is It Impossible to Get An Engineering Job These Days?

Human: Would you say that too many people are graduating with STEM degrees (more specifically engineering degrees) right now? Even if COVID wasn’t a thing? I feel like I’ve seen that the numbers of people who are graduating stem keep growing and it’s only going to get much bigger with all the big pushes for stem in schools. Assistant: I do construction design/management and we literally cannot find an electrical engineer. They searched for two years before they found me, we just lost a guy about 6 months ago and there are zero mid-level guys out there and we have maybe two entry level candidates who we are asking to come interview, they weren't reaching out to us.

Assistant: Never too many engineers. Engineers CREATE new technology which creates more jobs for engineers. If we magically tripled the number of engineers in the US we would have a temporary surplus but that would turn into entrepreneurial engineers making more work.
Human: In this article about making F1 engine blocks, the article mentions "filling molds uphill". What does that mean specifically? Is it like filling the mold form an opening on the bottom instead of pouring it from the top? https://www.racecar-engineering.com/articles/f1/techexplained\_formula1\_engineblocks/ Assistant: You inject from the bottom to control the way liquid flows into the mold. Think about if you're pouring water from the top, it'll splash all over the place and have lots of turbulence (resulting in less consistent properties and worse surface finish). By filling from the bottom, you're basically smoothly pumping liquid uphill, giving a much more consistent cast. In my field we call it countergravity casting.

Is it like filling the mold form an opening on the bottom instead of pouring it from the top? https://www.racecar-engineering.com/articles/f1/techexplained\_formula1\_engineblocks/ Assistant: No idea about engine blocks, but solid rocket motors are generally filled bottom to top via a process known as bayonet casting.
Human: What type of engineer solves spontaneous problems like getting a container ship unstuck from a narrow canal? ME major. Still thinking on what kind of engineer I want to be. I really want to be the kind of engineer that is as "hands on" as possible, and would prefer to minimize time spent in front of a computer. I've been thinking about who gets called out to solve problems like the one in the Suez Canal a few weeks ago. What is that job title? It sounds fun as hell so I'd like to look into it if it is even a career I could look into. Assistant: Ocean engineering guys and naval architects would be doing this. And some experienced salvage guys in operations. The major global players are mostly Dutch and Belgian companies, but most have US and other international offices.

Human: Is there an official term for a thing which starts to work after you hit it? Assistant: Mechanical agitation (the term is used in the nuclear industry)	Human: Is there an official term for a thing which starts to work after you hit it? Assistant: The Fonzie Smack.
Human: Engineers of Reddit, what's going into your house? Say you are going to build a house. You have a reasonable budget because Engineers live in the real world, but you get to say what that budget is because it's your house. What nonstandard design features will this house have? Assistant: I live in SoCal. In 50 years there will be no water. If I was starting from scratch I would make sure the water capturing from rain was ace, install a grey water system (laundry machine, shower, and dish washer water used for toilet flushing), and make sure the landscaping was both fire resistant and low water use.

You have a reasonable budget because Engineers live in the real world, but you get to say what that budget is because it's your house. What nonstandard design features will this house have? Assistant: In a cold climate, an insulated and drywalled garage is a must have. If you spend alot of time, get a garage heater installed. Air exchanger for the house is a must too in my opinion. No more stank air when it's too cold to open the windows.
Human: Traffic engineers of Reddit, how would you redesign the highways, streets, and other infrastructure of your city? Say that you have the chance to redesign the transportation infrastructure of your city from scratch. Would you re-route highways away from downtown? Add more turn lanes? Have fewer intersections? How would you do it? Assistant: I'm not sure I understand the question. For us, the politics are front and center to our work and the primary constraints we have to work around. If I had my way, I'd slap a grid network of exactly 350m blocks with alternating synchronization of 60 second cycles in every city in the world. But that would require tearing up a lot of land and pissing people off, starting with urban planners. It would also be a terribly boring drive.

Say that you have the chance to redesign the transportation infrastructure of your city from scratch. Would you re-route highways away from downtown? Add more turn lanes? Have fewer intersections? How would you do it? Assistant: I would have computerized driverless vehicles so intersections can do this: http://vimeo.com/37751380 except maybe sped up 300% as well. The cars would either have smart glass that turns opaque when passing through intersections or would have pants holders for all passengers and interiors that are able to be hosed out, for obvious reasons.
Human: I'm setting up my vehicle for overlanding and I have some ideas for power storage I need some answers to. So basically I don't need much as far as power so I'm wanting to use a power inverter that works on power tool batteries. The trick now is figuring out how to charge the batteries. I'm thinking of putting a small solar set up on the roof rack but I don't know much about solar and what would be required to charge maybe 4 battery packs. I'm also wondering if there's a way to set up a small windmill since I'll be driving a lot. And a third question, could you use a gas motor for RC cars to turn the electric motor from rc cars to create a mini generator? Assistant: Also may want to check out sailboat forums. They've been self reliant for power for years.	Human: I'm setting up my vehicle for overlanding and I have some ideas for power storage I need some answers to.

Lithium batteries, solar charging, etc.
Human: Are there Mechanical Engineering Jobs that don't use CAD design (like Solidworks or AutoCAD)? So I have recently taken a course in college called Engineering Graphics where we learned to use Solidoworks and AutoCAD. The teacher was absolutely terrible for the class and my experience here has made me want to avoid ever having to use AutoCAD or Solidworks again, if a career using them is going to be anything like I experienced in school. The teacher was awful at explaining how things worked and gave us very demanding assignments that sometimes we couldn't finish correctly. The tests were what were the worst. We were only given 50 minutes to design these ridiculously hard parts in AutoCAD and Solidworks and I never finished them on time. I spent hours outside of class practicing the concepts and using the software but the class was still a ginormous nightmare. I did better in my math and problem solving classes and enjoyed them more than this class where we were learning a "technical" skill that is apparently "commonplace" in the engineering field. Sorry if this is coming off as ranting, I just need to get this off of my chest after my experience in here. I don't ever plan to touch Solidworks or AutoCAD again, but I would just like to know from fellow mechanical engineers, does your job require this software or anything related and do you know of any ME jobs that don't? Assistant: Been working as a MechEng for 14 years. Haven't touched CAD since college. With that said, I wouldn't rule something out just because you had a bad experience with a poor instructor. Design work can be fun and creative.	Human: Are there Mechanical Engineering Jobs that don't use CAD design (like Solidworks or AutoCAD)?

Human: What happens to semiconductor fabrication equipment of older process nodes when newer process nodes are developed and how does this affect active products using the older process nodes? For example, the Intel i486 was produced from 1989 to 2007 and used 600 to 1000 nm process. Intel was using around 65 nm in 2007. Do manufacturers make the older products on the newer equipment or just keep the old equipment and assembly lines around? How easy is it to transition production of a product to equipment for a newer node without changing the product? Is a 7 nm node capable of producing 600 nm designs, since it should be easier to construct bigger transistors and most likely have better yields? Assistant: An interesting problem arose that caused automotive manufacturers to run into chip shortages. Lots of chips in cars but cars are designed close to seven years out from day one introduction/production. So they’re using older bigger chips available at time of development and design. Thus as fab plants convert to smaller and smaller chips fewer fabs can build chips, chips designed and used for cars.

Assistant: How does machines make something that small? I only know of cnc and etching pcb’s… and I can’t imagine any of that style of manufacturing can get down to nanometers… is there a search word I can use on YouTube to settle my curiosity? Edit: I’ll answer my own question. I searched for integrated circuits and found this https://youtu.be/ThNW0EqOH7U
Human: Any engineers here who work for Elon Musk? What is your experience? I am currently in school for engineering. I would like to one day work on one of Elon Musk's projects ( tunnels, SpaceX, etc...) and am wondering how realistic or idealistic that would be. Assistant: I have a lot of friends there. Work till you burn out, or find a fragile equilibrium. If you like working around 60 hrs/week and want to get into those fields it's not bad, but It's far from my ideal job or first choice for an aerospace company. Designing bolts on a spaceship is no more exciting than designing bolts on a shopping cart.	Human: Any engineers here who work for Elon Musk? What is your experience?

Human: Is there such a thing as "Optical Engineering" or something like that? I've been really interested in getting more into the technical details of AR displays and what makes them work but I haven't been able to find any specific "engineering field" that covers it. Is it just something like Mechanical engineering with a specialization in optics? Assistant: Usually people wanting to get into optics will get their undergraduate in applied physics with a focus on optics or photonics.

I'm a Mechanical Engineer and I worked in AR Optics with several Optical Engineers, happy to answer questions. University of Rochester is by far the top school, because of Kodak legacy (and Corning), and University of Arizona has a lot of expertise on larger systems because they manufacture all the big telescope mirrors for NASA. Edit: https://kguttag.com has the best AR Optics industry analysis
Human: Everybody I work with seems to have at least one patent. Am I just a crappy engineer? How common is it for mechanical engineers to have patents anyway? Assistant: There’s success bias, here. Most don’t have patents, but you hear about the ones who do. It all depends on what you do and what markets you’re in. If you’re in academia, you have publications, but in industry a publication isn’t worth much. It doesn’t make you a bad engineer at all. Quit that negative self talk and get back to kicking ass.	Human: Everybody I work with seems to have at least one patent. Am I just a crappy engineer? How common is it for mechanical engineers to have patents anyway? Assistant: It all depends on what sort of work you do, really.
Human: Settle a debate: better to leave the air conditioning on when you’re out for a few days or off and re-cool the house? HVAC types- I’m in New England and it’s hot but not Portland OR hot. We’ll be out for 2 days and the temps will be in the 90s. We have several mini split systems in the house. When we leave it off for for a few hours the house gets up to the 80s but seems not to go above 83/84 inside. It’s fairly humid so the dehumidifier aspects are one of our concerns. If we do turn on the A/C we leave up pretty high but enough to cool a little. So on or off? Assistant: Since you asked engineers and none actually gave you an engineering answer, here it is. It is more efficient to turn it off. Newton's law of cooling tells us that it takes less energy to cool intially and it gets exponentially harder as the temperature is lowered. Therefore, keeping the house at a lower temp for an extended period of time uses more energy, because cooling the house from 84 down to your vacation setpoint uses very little energy in comparison to holding at that setpoint.

The only reason to consider running it is humidity, but that's not a big issue in new England unless you have a basement that's getting damp and you can get a dehumidifier for that.
