Dope Tech Episode 2

<<@anns666 says : Same Problem in space>> <<@eltamarindo says : For those looking for the location in question, Vertasium is likely basing this quote without further research: "Eventually, Intel’s May and Woods traced the problem to their chip packaging modules. These packaging modules got contaminated with uranium from an old uranium mine located upstream on Colorado’s Green River from the new ceramic factory." The Green River point source may have been in Utah and the ceramics factory may have been downstream on the Colorado River in Grand Junction. "The CoorsTek facility in Grand Junction, Colorado, officially opened its doors in 1977.">> <<@lebonjean7146 says : Interestingly, these modules could have been used to make real random generator at a time it didn't exist.>> <<@rxsolomon says : Even without compromised packaging, smaller and smaller DRAM cells could be flipped by alpha particles in the environment. In the early ‘80s I helped Texas Instruments sell a fast, highly integrated error detection and correction chip, the ALS632. “The SN74ALS632 is a vintage 32-bit parallel error detection and correction circuit (EDAC) originally manufactured by Texas Instruments. It was a core LSI (Large-Scale Integration) logic device developed for minicomputers and high-performance microprocessors in the 1980s to identify and correct system memory faults.”>> <<@FlashBureau says : A Short that actually finishes its thought without holding context hostage? That's not content, that's a unicorn delivering a full thesis in 60 seconds. Veritasium out here flexing on 99% of the platform.>> <<@angelg3986 says : So that area is still poisoned 🤢 with uranium I guess>> <<@ovpupfish says : Alpha particles have very little ability to penetrate. Those affected junctions must have had the alpha emitter on the very bottom face of the packaging next to the junction. When the test was done with alpha emitters, was it done without the ceramic packaging?>> <<@Tan_cannon says : So is nuclear weapons are safe behind the firewall ?>> <<@DSWL_ says : ☝🏻🤓 truly fascinating ya big fkn nerds>> <<@kleinebre says : With respect, neither sound like Mr. May's own custom guitar.>> <<@matthunter1424 says : Now we are being asked to test semiconductors to 20 Gy of XRAY. Boards used in AI datacenters are remarkably complex and to assure proper assembly they need high doses of Xray. Typical dental XRAY is a few mGy.>> <<@jt92 says : It's actually refreshing to see an actually informative, well-written short with no shitty background music.>> <<@fyrstormer says : They should've rebranded them as true random number generators.>> <<@Donbros says : That is awesomly practicsl engineering example>> <<@Donbros says : Honestly its kinda bs if they are so sensitive to a tad bit uranium>> <<@markmeadows7093 says : So I wonder what that stuff is doing to our bodies. I am going to have to research this.>> <<@JonArnett says : My working theory was cosmic rays, not terribly far off.>> <<@waroftheworlds3173 says : All hail the jobs of the manufacturing plant.>> <<@Play_Streams says : Intel have really seen everything.>> <<@russk5513 says : Is it amazing what a little "Contamination" can do to product outcome in unexpected ways? Such as the global grounding of aircraft with Pratt and Whitney engines of a particular series that had the powdered Blade and Hub turbine metal contaminated and even now aircraft that's only 6 years old sits on the ground waiting for rebuilt engines(1 year) to be installed.>> <<@jonmarquez128 says : This was a contamination found in the ceramic mixtures used in making of electronics.>> <<@sergeyd5777 says : 1) Uranium does not emit Alpha particles. And those isotopes that do, they have a very short lifetime (counted by months). 2) Alpha radiation is not penetrating. It can be literally stopped by a sheet of paper.>> <<@radarmusen says : Sounds like they discovered a new kind of detector.>> <<@davidthacher1397 says : I would call this a high level take.>> <<@bennybongosbigolebonanza894 says : Is that a PRAM? I have a vintage Simmons e-drum that has interchangeable PRAM’s containing different drum sounds. It looks just like that. Neil Peart could change his mid-fill. (Joke).>> <<@andrewbeattieRAB says : AS LONG SS the people on the river were able to buy computers with absolutely clean chips before they died from cancer.>> <<@davidespinosa1910 says : Alien technology for 1978 ! 0:15 👽👾🛸>> <<@choobeedog says : Single event upset = bad first date>> <<@tonylopez5937 says : Please consider not embedding the text of the spoken words into the video. It blocks the images and distracts my attention from the visual and spoken content of the video. If I want to read exactly what someone is saying, I'll turn on the closed captions. Thank you.>> <<@ChrisNotTheKing says : New Horizons vs. Voyager 2 ... who'd win a battle?>> <<@robfut9954 says : I’m pretty sure this was Green River in Utah, not Green River in Colorado>> <<@DjF7-l8r says : 🎩💙🍷🖖❄️>> <<@acmenipponair says : This by the way nowadays saves our astronauts from dying. Because while the number of alpha particle decays that hit a RAM chip is quite small when you leave the packaging uranium and thorium free (and nowadays RAM chips are not even casted in huge ceramics anymore, only a small layer), finding out why the RAM flips happened is important for outer space vehicles. because there the cosmic rays as well as the solar winds produce way more radioactivity than here on earth. And nowadays our chips are so small, that also a beta decay can reset a bit of RAM or a harddrive, SSD etc. And imagne is the bits of important settings of your vehicle, for example navigation settings, get changed. Then you don't fly past the moon, but hit it with full speed. But because science knows nowadays that this is possible - they do counter measures against it, like reductive backups, where the computer of the vehicle checks for bit differences as well as better shieldings.>> <<@kanab...prates2103 says : Ohh, so that's the new Private Equity owned channel!>> <<@MarinusMakesStuff says : My heart goes out to all YouTube channels that haven't been bought by private equity yet. Sad to let Veritasium go after all these years. Derek, I followed you since the start.>> <<@KaramChand-zm6zj says : 😮>> <<@hellmalm says : Also gave birth to ECC (Error-Correcting Code) memory. Because bit flips can be really dangerous in let's say an airplane control system. And yes bit flips can occur with background radionation that increases at higher altitudes because of cosmic solar radiation. So since the 1990s Modern Avionics (1990s-Present) have ECC memory.>> <<@usertutubo06 says : There's radioactive uranium in the river. Oh no! save the chips!>> <<@DMAZ1776 says : I assumed it was click bait based on the first line. I appreciate one person not stealing content out of context for shorts and views. Well done! 🎉>> <<@Waldie23 says : Ya the amount of carbon 14 decay is enough background radiation to split the discernment clean off a athieest’s conscience ?>> <<@abberss says : Externalities are a bitch. PUNISH POLLUTERS>> <<@김진영-o1d5j says : The production quality is amazing I enjoyed every second of it.>> <<@TurklesMusic says : At the alpha particle level … amazing!>> <<@tomsunhaus6475 says : Remarkable! Explains why Intel occasionally has problems.>> <<@STOP_FAKENEWS says : intel is dead, so trump DEMANDED taiwan to give all of TSMCs secrets to intel, - america is finished>> <<@mizoid says : Why am I looking at this at an odd hour?>> <<@MultiSenna12 says : This real technology and software is not technology>> <<@PetCactusA_HarmlessLittlePrick says : Oops. 🤦🏻‍♂️ 🤦🏻‍♀️ 🙄>> <<@MrMeltdown says : Nowadays, They also use CRC internally which can detect and correct one bit errors>> <<@TheBooban says : And then they gave away this knowledge to competitors for free.>>
