<<@veritasium says : Use code VERITASIUM to get 50% off your first monthly KiwiCo Crate! https://www.kiwico.com/VERITASIUM>> <<@yukon4511 says : Great video, but Dust? Seriously? Dust? Not even a chemical composition? Other jet engines operate in the same conditions, and don't have plugged turbine blades. Remember when they used to say it was ground level pollution in 3rd world countries? I guess that didn't fly with said operators.>> <<@BrianHarris-p7r says : This was exactly what I needed, thanks!>> <<@crimlex3733 says : I want to understand this so bad but I have a hard time wrapping my mind around it. I think there is a reason as to why I went into humanities/social science at university.>> <<@MiltonWarmikael-o1m says : Anne should place some tiny imperfections that take years to fail catastrophic.>> <<@davidb1412 says : My god, how much do these damn engines cost? Everything shown here is nothing short of magic. The fact that science has brought us to a place where this works is almost beyond imagination.>> <<@ganeshramg.s7715 says : Can anyone say why this can't be implemented with steam turbine>> <<@ivanbakalov6211 says : I love aviation, couldn't become a pilot, but this was one of the best and most detailed jet engine videos i ever saw ❤ thank you 🙏>> <<@manojisaac4978 says : Excellent video❤>> <<@YASHRANAreview says : india have genious minds still they are arent able to build one , the reason is very simple. the government have to create an entire " " for the scientist to deliver the results>> <<@pgabrielrr says : 9:37 I thought "this is reality itself rendering in real time before my eyes" and I started crying. Science is awesome.>> <<@pgabrielrr says : i like to imagine that jet engines for mechanical engineering is like the chip of a Ryzen Threadripper for electronics>> <<@guyyoav says : Tnx for the amazing info>> <<@aesir786 says : MORE SHOCKING FACT IS ABOUT A PHONE REDMAGIC 11 PRO its cooling fan does 24000 RPM whereas jet engine does 12500😂😂😂😮😮😮>> <<@hassanteymoury6317 says : Really beautiful>> <<@WilliamFortune-y4g says : Almost everything is molecularly a Crystal . Trees are made from cellulose which is sugar so it technically is a candy cane forest>> <<@pleum266 says : Please make this video a Thai audio track.>> <<@soulfunkjazz says : Fun fact: Half of a jet's price tag comes from its engines.>> <<@AWKuhns says : This is the best Veritasium video I’ve ever seen except for probably the next one. Thanks so much.>> <<@shug831 says : I can remember working at RR, Hillington, A Block, back in the 1980's where they were forging titanium fan blades. The steel dies were worked to +-0.0002" by hand. The question I have is, who makes the wax casting die that produces the wax blade?>> <<@Apisii43e4 says : I am an undergraduate mechanical engineering student and watching this video gives me a sense of appreciation for my engineering discipline and engineering and physics in general. 🔧 ⚙️ 🫡>> <<@sjoerd1239 says : That is all very well and interesting, but the blades still do not run hotter that their own melting point (or their immediately adjacent environment). For a production that relies on precise scientific explanation the bait language is BS and off putting.>> <<@stuckinthemud4352 says : So what you are saying is it's dramatically more simple than a car engine>> <<@stuckinthemud4352 says : lol wait until these guys find out that cars run at 200 and blow up at 250 or less.>> <<@Trentnathan77 says : I love these examples. But i cant help think if your an engineer or physicist they must think that most people are really just dopes. Thankyou people that make our little lives just work.>> <<@evanrossman2804 says : my best guess is the conductivity of the metal, the decompression of the air out the back side cooling down and a form of Leidenfrost effect, so the super-heated air never really comes into contact with the metal. But i don't have a degree in anything, so what do i know?>> <<@ashishroy8201 says : It's so crazy we made all that out of sand>> <<@pradyutsarma8021 says : don't miss that the majority of the dust, water during rain or any FOD (foreign object debris) is actually handled by the primary compressor fan, the first one, and due to the centrifugal force it forced to the bypass duct and it doesn't go through the main engine>> <<@DertyMike says : We slapped wings on a giant metal dildo, put rotating blades of death on them, and blow up luquid dinosaurs to travel vast distances in record times. Yet people still complain about a 15 minute delay.>> <<@74wrighty says : So cool Rolls Royce let you see how they are made.>> <<@benheitz4248 says : I thought after this video I’d feel safer in planes… I thought wrong>> <<@brianmurphy1227 says : This is one of the most well crafted and informative videos I have ever seen on any format. Not just YouTube. Thank you for this.>> <<@anthonycade9034 says : What about using a super magnet when cooling the crystals to get them to all line up the same way…maybe even stretch them?>> <<@NoodleDemon77 says : Imagine you tell your friends that you grow metal>> <<@mimimotor says : How to mislead the Chinese IP mafia>> <<@jaikris-eq3mo says : the unthinkable sky gods....>> <<@Nick_Bottom says : Telling a skilled worker that she should be replaced is gross. Kim should’ve slapped you.>> <<@Zombiesinyourbrain says : They grow silicone microchips in a similar way>> <<@jaycray says : You lost me at V squared>> <<@ash-e5f5n says : Can a piston be made with same process?>> <<@ash-e5f5n says : This is crazy thanks for taking the time to make vid I've leaned a lot I have a question on a race car I've seen temps 1200deg cylinder exhaust temps I'm sure they use 4030 aluminium or 6063 something along them lines Is this the same principle?>> <<@nostradeniz says : Incredible that you basically summarized the fundamentals of my entire statics, material science, strength of materials, and a good bit of my thermodynamics curriculum I studied when becoming an engineer all in about 10 minutes.>> <<@sawankumar-zu4qy says : my only question who created the universe>> <<@amanfromthewest7326 says : The twin towers melt at 451 degrees>> <<@podunkest says : I was shocked to learn, years ago, that in terms of crustal abundance, titanium is the 9th most common material in the Earth's crust and is basically every bit as abundant as Iron. The key difference, and the reason for it's almost mythical status, is that it's far more difficult to process and titanium loves binding to oxygen whereas iron is ridiculously easy to process in comparison. Titanium is more common than copper, nickel, tin, lead, zinc and even carbon in the crust.>> <<@mikethe1wheelnut says : You're missing a factor of 1/2 in your second equation for kinetic energy, 4:04..>> <<@richardcochran260 says : My first job after college during the 1980s was as a software engineer for Pratt & Whitney, working on software used by the engineers to design the complex shapes of those turbine blades and vanes with their cooling holes. Most of this was already explained to me during my time at P&W, but it's still fascinating to see it.>> <<@Bikewithlove says : Awesome episode, thank you :)>> <<@CoreVision24 says : Meanwhile my laptop melts at 3 Chrome tabs °C>> <<@PudingXD says : 11:18 For what I heard the first jet engine was a pulse jet engine made by the nazis around the similar time period>>
