As a cybersecurity engineer, I cannot hype up NIST enough. They maintain this security database that contains all known software vulnerabilities in existence. Every major company, government and military is using this database to check for vulnerabilities in their infrastructure. Thank you NIST.
@anon you do realize the fact that they sell the references that are required for companies to meet national standards means that NIST is able to be self sustaining, right? If your complaint was for making your peanut butter 2ç more expensive because they have to calibrate their equipment every so often, it would make sense.
@Ben Hook we use SECP256K1 in blockchains, Bitcoin, Ethereum, which isn’t a NIST curve. It’s Koblitz curve. SECP256R1 on the other hand is a NIST curve. I used to wonder why Satoshi chose non-standard curve. I assume this is one of the reasons why.
@Patrick Sanders Because that the lame power of conspiracy nuts, aka cookers. They pretend they have secret knowledge to hype themselves, and the sad thing is that they may well believe their own delusion.
Deeply interesting! I love to read, listen and watch content like this. From my point of view, serves as an introduction to the behind the scenes of how things in the world are organized. This video in particular made me wonder whether the equivalents to institutions like this exist in other countries like Mexico or Japan.
Here in Germany we have DIN (German Institute for Normation / Standardization). The standardize a lot of stuff, from paper sizes (just think of DIN A4) to combustion fuel compositions. I don't know for sure if they have their own SRMs or if they use EN, ISO or NIST SRMs but they standardized a LOT of materials and regulatories.
The Charpy test is indeed an important standard test for steels. It measures the toughness, or resistance to brittle fracture, using a standard notched specimen. Materials prone to brittle fracture are to be avoided (or mitigated). Ductile fracture does not sound so good either, but if something is going to fail, ductile failure is safer and preferable as it requires exceeding design loads to achieve this. Brittle failure is of concern because it can occur at less than design load conditions. The typical units of measure are energy (absorbed) in Ft-Lbs for imperial unit system, Joules for SI units. Metals and most solid materials become more brittle as temperature is decreased. Higher values measure in this test are better than low values. Brittle high strength steel may yield single digit values, whereas low strength austentic stainless steel may yield 300+ Ft-Lbs, meaning it takes a lot more energy to break it in a notched impact specimen, even though it is not nearly as strong. Different metal alloys and heat treat conditions will have different temperatures at which they become brittle (Ductile to Brittle Transition Temperature, or DBTT). The temperature at which the test is performed is based on design standards and factors such as the end product's minimum design temperature, and the material's expected DBTT. If the material is produced correctly, it will meet or exceed certain impact energy values at a given temperature. If not, it may produce low values and indicate sub-standard material. The notch of the specimen, which is the designed point of failure is machined to precise dimensions for the purpose of consistency. I am a Metallurgical Engineer and thought I should delve into sharing my personal understanding of that part of the video.
@Scott Rackley Good point. Toughness is not a required or necessary property in some materials and some applications. It is in structural and pressure containing products, but typically not in tooling. In fact in tool steels, low toughness often times is very acceptable in order to get the high strength or wear resistance that is required. Hence tool steels when they fail, tend to fail in a brittle manner.
Charpy is just one way to measure one variable in a steel. Many times in tool steel you don't really care too much about that value, and are looking for wear resistance, such as drawing forms.

Great video and I do not know if anyone proposed that here, but it would be really interesting to see HOW are they measuring exact values of elements or nutrients in various samples in another video :)
Using basic chemistry tests. Chromatography, spectrometry, spectrophotometry, reactions with Lowry, BCA and other kind of chemicals with standard curves, etc
What an episode... N.I.S.T is freaking awesome!!!! absolutely mind blown how accurate their Standards are. Its amazing!!!! Great video as always VT!!!!
@anon whats actually amazing is how you’re spamming comments about your non existent tax dollars instead of getting a job, and not realizing an organization that sells 50 units of standard limestone year on year for over a century along with thousands upon thousands of other standards is clearly a valuable resource. Unlike you.
As someone in the analytical chemistry field, these standards are vital. It is how analytical labs are able to charge such a price for what seems to be them just analysing a sample.
@Kenneth C nobody does it because its required for consumer trust, yet extremely hard to make profitable. For a business, buying a couple SRM units every year is a rounding error. Use your brain.
@teranyan If a single SRM batch requires hundreds of labor hours and a million dollar lab and tens of thousands of dollars in reagents and supplies to analyze, yeah its justified. Use your brain for once. Consumer peanut butter isn’t $1000 a unit because consumer *factories* have economies of scale and don’t need teams of scientists to test every batch, precisely because standards agencies like NIST produce the standards needed to calibrate the industrial testing equipment in the factory.
I'm a pharmacist and always ensured my students knew that the temperature monitoring devices (basically a thermometer) for the refrigerator/freezer that holds medications must have a certificate of calibration tracing its accuracy back to NIST, as well as ensuring they knew those devices do in fact "expire" and should be re-calibrated or, more practically, replaced. Great video to get to see the rest of NIST's world!
@Carlos L that's a critical job! I need confidence that my vaccines have been kept at refrigerated temperature before they go in anyone's arm. The temperature monitoring is only a small example I'm sure of all the devices that patients rely on to perform with a high level of precision (and accuracy).
@Xnoob Speakable they're digital, but outside of that I have no idea LOL. But over time, they will 'drift' and read 1 degree higher or lower than actual.
The director of NIST seems to me to be one of the most approachable and likeable civil servant to whom I've ever had any exposure. You're a cool dude, sir! Your general state of apparent happiness is enviable.
@anon you know, YOU'RE RIGHT! LOL. Thank you for pointing out that mistake. And, now that I'm reading all of this again, $183K per year, HALF of that which the president made up until just a few years ago, that's too much for peanut butter in the public space.
Proper storage conditions would help, but some substances, like B vitamins degrade easily. I imagine they test older stock against newly made material to verify before it can be sold.
This is like a Human Archive. Archeologists are going to find this place in the future and have a mindfuck trying to figure out what the area was used for.
NIST also played a pivotal role in standardizing internet communication protocols. Without them, the Internet would be a much more chaotic and much slower
@Jordan you seemed to miss the part about standardizing communication protocols. Which makes sense considering idiots like you cry government overreach at everything but can't get up off their arse to vote for someone else
Should there be a gathering of materials like the dust every decade or so to check in chemical and other differences to the environment over the years?
I love how passionate that guy is about his job. You can tell he loves so much about what he does, and he is so excited about it and it makes me really happy to see.
Despite how it looks like, and oddity that he is so popular, this guy exactly is desperate only for recognition and for all to think, that he is very smart and unique, kinda sickening A lot of times he is proven to be wrong, but he never acknowledges that And why some truly great creators a friends with him is also a mystery Always quadruple check what you hear from him, that’s a very good chance that he talks total BS
@Daniel Z Yep, taxpayer funded salary working for the corrupt government. He could care less about all the crimes the government commits so long as he gets that fat paycheck. Typical of government employees
Just makes me think that, in general, there's so many people with really deep knowledge and skills that are working away constantly to keep our world safe and operational. It's very useful to remember how we're all so dependent on people like this.
I am not a science nerd or in any profession that depends on this kind of information and I was fascinated and amazed by this information. Thanks for making this available to your average little old lady. We are never too old to learn.
Worked at A Military Calibration Lab (PMEL) as a scheduler. Opened my eyes to not only Standards but how temperature and humidity in the lab is so important. Never appreciated prior to that as a Mechanic how much work went into that sticker on the equipment.
How often are these things updated? Because dust in our houses now is probably very different from 90s dust based on different microplastics, products we use on our bodies and furniture etc.
@mattg706 He may be talking about the particular jar. He also didn't specify that he wouldn't be able to find out how old it is. I did find it odd too and still do.
Its updated occasionally. I'm not sure how they decide the expiration schedule but the website shows House Dust as revised in 2018 and expiring in 2025.
I was really surprised to hear him say "i dont know if i can tell you how old this is". For such an extensive process it seems like such a small yet important detail to leave out when dealing with a lot of these things.
It's amazing how complex our world is and how we depend on systems that 99.9999% of us have no idea exist and can't possible be thankful for. Thanks for giving me this knowledge and sharing such important research with the world Derek. :)
@Rob Woodring can I send it via HAM radio or its equivalent? That'll cut a lot of time off the objective. If I have to produce two display monitors, it's gonna be a while. :)
@Inverted Flow the good thing is that when the material scientist that works with semiconductor is using their computer for work, they might not understand fully how the Google Chrome software or any other work related software is working, but software engineer will!
Yep - my father is a soil chemist that runs quality control programs for soil testing labs. There's way more of these labs than you think, because they're used by farmers to determine what kind of fertilizer to put on their fields (among many other things). What's fascinating is that because the QC program is so large, the excess soil is highly desirable by labs to use as reference and calibration material for equipment. And that's how he ended up selling buckets of dirt internationally.
I've been following your channel for like 10 years and this right here is a holy grail video. I have had this EXACT question (the one this video answers) in my mind probably since the age of 5. My fascination with Nutrition Facts on boxes has been life-long and I have always wondered _how_ they get that data, and _how_ they _prove that it is exactly accurate to what I am eating_ . And now this video shows me that it's because of a thing called an *SRM* or, *Standard Reference Material* ! Genius.
Many government agencies are less than worthless and people interact with them unwillingly(At gunpoint when you get right down to it.), but NIST is different. As a machinist, I've known about them for decades and regularly benefit from their work.
Agreed. By all means folks, have your gripes with the government but something like NIST could never come into being without a functioning, well-funded government.
Oh my, I love this video so much. I have long been fascinated and humbled by the standardization efforts in the world. ISO, ANSI, and innumerable technical standards, all of which probably at some point in their development interact with the tangible products NIST produces to actually substantiate their standards. These are the mechanisms that make modern society function. They are foundational to the quality, reliability, and consistency of almost every single moment of our lives. It would be a dream to contribute to that.
I owe my thanks to the sponsor of this video and to veritasium so that I can finally have my own domain that I can use to make a website for all of my socials
I like how human civilization eventually came up with such a system. We frequently do not realize how amazing some of these quality of life things are since we're so used to it being a background part of our everyday lives (which is good)
@_Wayward_ I got a lot from the video. Multiple examples of needless complication. If you want to make peanut butter, start smashing peanuts. Sell the products of your smashing efforts. Peanut butter. End of story. Hint: 50 lbs of shelled and skinned peanuts yields 50 lbs of peanut butter.
I’m in my undergrad, and I worked on a project that was examining mercury deposition. One of the things that was done for the project was measuring certain samples we collected for mercury. Reference standards were used for that, we used soil standards. It was very interesting to learn about how important these standards are.
I am always happy to see that a branch of the government is efficiently doing it's work. I don't know how to feel about the fact that this is a... poop-related work, though.
CNC Kitchen is a guy on Clip-Share who built a testing machine that works in exactly this manner, and shares tests of 3D printing materials and techniques so everyone can improve their processes. He also does a bunch of other quantitative testing, and it's incredible that someone was willing to take on such a job just for the Clip-Share revenue.
I'm a medical lab tech, and I find NIST to be fascinating. We use standards (we call it QC) to make sure that our analyzers and methods are working properly and giving accurate results so that you get the care you need next time you're in a hospital. Our stuff's not cheap either.
NIST is one of, if not the, most under appreciated of all US government agencies. I was lucky to be able to tour their metrology lab in Gathersburg, MD in 2007. It was just mind blowing.
As a metalurgical engineer, We use standard materials all the time. Typically, different grades of steel and iron to calibrate spectrometers for chemistry readings to verify the heat. Any sort of materials engineer uses some form of standard material, it's nice to see where they come from.
As a pharmacy student, I find this quite fascinating as we would learn of formularies and drug standards - and finally witnessing such an organization like this exists really broadens my horizons for how important "standards" are to the practice of various professions even non-medical ones, really!
@Veritasium. Just curious how do they determine what chemicals or bacteria came from the human feaces. Since we use strong or mild chemicals to clean our toilets and some through away dead fish etc in the toilet which could also contribute to bacteria etc. I am sure there is a way to exclude such sources, however cannot think how this is done.
For several years, I worked right across the street from NIST in Gaithersburg, but I never knew that they had a warehouse in there! I certainly am aware of what they're doing in general, but was completely oblivious of this. Neat!

This is one of my favourite videos of yours, ever! Soooo interesting, and I learned things I never thought about that now gives me immense satisfaction just knowing. Thank you, Derek & the wonderful people at NIST!
I would hope so. The point of a standard reference material is not to have a perfect material free of defects, but rather to have a material that has been analyzed so extensively that it can be used to calibrate measurement tools. So if I have a sensor that's made to detect a particular set of manufacturing errors, I callibrate it using a reference material with a precisely measured amount of each error. My sensor is accurate and calibrated correctly when it measures the same amount of error measured by a reputable source, such as NIST.
Didn't Veritasium already do a video about this place a couple of years ago? I remember watching one, and I can't think of who else would have done it among the youtubers I watch. Edit: nvm it was Tom Scott

I used to work as a chemist in a materials testing lab, and we used NIST metallic standards constantly. Our machine shop even machined a lot of those charpy standards for NIST!
I worked at a place called E.W.I.(Edison Welding institute) ours were made from plate that were fused with proprietary welding materials to determine whether or not it was an acceptable application for the customer. We also machined "dog bones" to test tensile strength.
I work in a hospital lab and we use standards all the time to calibrate our test methods and make sure they're running properly. It's interesting to see how the companies that make their calibrators and control material have to calibrate their instruments using a standard from NIST.
I work for a company that produces every type of analytical measurement instrument you could ever think of. We use NIST reference materials every day to qualify our instruments. We call them SARMs though, standard analytical reference materials. We use NIST steel spheres to calibrate our density measurement machines. They produce a great product, and are vital to industries like mine. Keep up the good work guys!
@ben let's say that you know a scale can accurately measure 100 lbs, 150 lbs and 200 lbs because you used only references of those three weights to calibrate it. Does it mean the scale can only measure those 3 weights? No, it means it can measure any weight between 100-200 lbs within a small margin of error.
@ben to expand on what James said, take note that the NIST rep said they take samples. Chemically those apples are very similar, but to account for those small differences that's why they blend them. That's why it's a "standard" instead of "chemical model of Granny Smith" apples. It's a baseline, nothing more, nothing less.
@ben That variation is irrelevant to the standard and device being calibrated. If I know my scale can accurately weigh an object to a very precise degree then it doesn't matter what I weight after that.
It's oddly satisfying to know that this amount of science, analysis and 'know how' actually exists. I often question myself and everything, that leads me to wonder what 'everything' is in everything... lolol
Working in the lab of a sewage treatment plant, was interesting for a while, but then became insanely boring, but one neat thing was the fact that the more accurate our scales were, and also our ability to dispense the necessary items for testing, the smaller the test sample could be, and therefore the less of those necessary items would be used as well. Our scale was so accurate that we could weight our fingerprints. We would have elementary school kids tour the plant from time to time, and we would pick one to pickup a beaker while we turned our back, then we could correctly tell them how many fingers they used to pick it up with. We did have to instruct them to use the pads of their fingers not the tips to make it fair, but as long as they played fair, we had a 100% correct “guess”, and the kids absolutely loved it. We also typically picked a kid that was somewhat socially awkward, which made them the big shot hoping to help them socially.
@Yeekthoven I'd say "carve that into a stone tablet and bring it to me on foot" but you can imagine how geeky the people how invented writing systems and stone tools were.
@A J Wright geeks don’t build the world they destroy it. All these technological advancements are leading to nothing good. We’re destroying our environments, atmosphere, bodies, and eventually our own species through weaponry or AI. All because “geeks” can’t resist biting the apple.
When I was in the military, I used to work in calibration (AFSC 2P0!!!) so I knew a lot about the NIST tracability for our standards ... but all this stuff was pretty damn neat to see, and a side I never knew about.
I work in an analytical lab here in Brazil and I use a lot of this peanut butter reference material as a quality control for mycotoxins, fatty acids and metal ions in food. It smells so good though! And thanks a lot for these people that work at NIST and make this reference materials. You guys rock!
@Unified Theory of Life There's a difference between radiant heat dissipation and kinetic energy transmission. It's the principle used in controlled demolitions of structures that were designed to withstand these heavy impacts. While a giant ~205000kg jet slamming into that building at 750km/h would only have generated around 7-8 giganewtons, the explosion of 90000 liters of jet fuel added anywhere between 70 and 150 giganewtons, which brings it to the realm of what is used to bring down even larger buildings. For comparison, the demolition of the significantly taller Mina Plaza only took around 6000kg of explosives, which was of a class that would have generated only around 50 to 80 giganewtons, barely over half the force that plane crash event generated. While the efficacy of force delivery is certainly much higher in controlled demolitions, it's not hard for 30+ floors of falling structure to make up for the rest, especially when structural integrity gets compromised more and more with each impact. Additionally, most demolitions prefer to go over the force requirement if possible and add more explosives / reduce section distance between explosives, not because there isn't going to be enough force, but that it's simply cleaner of a job when there's less structure to take impacts. I'm sure the fires didn't help things stay structurally sound either, but to be honest they may very well have been completely irrelevant at this point. The structure doesn't have to be exposed to radiant heat, just vibrate enough to the point that it lowers its structural integrity so that it can no longer support the weight of what's above. Once that gives, impact force from the falling section will create further vibrations that further destabilize the structural integrity of what remains. If you're lucky, or unlucky in the case of demolitions, it stays standing. Most of the time, it does not. On a related note, this is the reason why skyscrapers (and increasingly even mid-rise buildings nowadays) built on the pacific ring of fire (Japan, New Zealand, Taiwan) employ technologies which allow for the structures to take reduced vibrations from earthquakes. The main difference is the way the energy is delivered, with earthquakes predominantly consisting of maintained lateral forces, as opposed to one big delivery from an event like 9/11 or a controlled demolition, but earthquakes can easily deliver enough kinetic energy to destabilize a building.
I love this! I think in a different life, I would have liked to go into the sciences as a career. Unfortunately, I am terrible at math. Even a science/research that is seemingly "mundane" like this is very fascinating to me. :)
I learned two things today. 1. These people's work is definitely underrated. Now I understand how some foods and products can exist for years and taste the same. Consistency is key and these people are definitely helping with that. 2. I'm never eating peanut butter anymore. 😅 Never again.
Most bigger peanut butter brands do not contain aflatoxins in any major amount and there is no need to fear for liver cancer from eating most peanut butters in developed countries. There's a bit more that can get by with smaller brand natural peanut butters but again, not something to really worry about. On that note, aflatoxin is a toxin found in molds from peanuts, corn, other grains and in less developed countries that make peanut butter in less sanitary conditions, more may slip by. Derek makes purposefully misleading comments like this all the time.
Possibility of toxins aside, peanut butter is one of the most calorically dense things in your kitchen Unless you're on a bulk, you shouldn't need all those calories anyway lol
Hi Derek! Awesome video as usual. I appreciate that you expose me to topics I never would known about but still interacted with. Can you cover the concept of "targeted ads", "online reviews", "the high income job market", "the need for pillows", "visas/passports/international boundaries/citizenship" ? I'd love to see what side of these topics you'll uncover!
This was all very interesting, but now I just want to know how long the mixing period is for each standard unit. Is the mixing period for house hold dust the same as peanut butter? I'm assuming there is some sort of standard with the viscosity of each material. What other secrets are they hiding in these srms?
@bill ted Everything has a margin of error. We cannot get down to a discrete level of detail. We don't need to though. Significant Digits exist for a reason. It only needs to be good enough.
Handling a 50 micron spherical ruby single crystal from NIST to calibrate X-ray diffraction equipment has been one of the scariest experiences I ever had as a researcher... I had nightmares about dropping it on the floor and losing it
@Butters Da Baller Fun fact: the head gap on an audio cassette player is not much bigger than 2 microns, possibly even smaller. A human blood cell is more than twice that in diameter.
@Fred Werza the Phrozen Sonic Mini 8K has 22micron XY resolution for less than $500. It’s remarkable. The biggest limitation holding 3d printers back now is chemistry and time.
I always wondered how society got by without places like this, and apparently it turns out they do exist and they're exactly what you'd imagine. A bunch of engineers standing around and saying, "This is standard."
I'm curious how many people work there. You'd think it would require a whole range of experts from different fields to standardize such a variety of materials. Perhaps it's not as difficult as it seems in many cases but I bet they have different people for things like industrial materials and microbiology for example. Fascinating
What I find amazing about these videos is how US government agencies affect not just the lives of Americans but people around the world. From NASA to NIST to the CDC, etc.. it's truly amazing how these agencies affect people around the world directly or indirectly.
This whole video is super interesting! And surprisingly, even the sponsor segment was something I've actually used and am familiar with instead of some random site I'll never use lol

This video in particular made me wonder whether the equivalents to institutions like this exist in other countries like Mexico or Japan.
We don't follow same standards but there are standard institutions everywhere. In Europe, we don't follow the FDA but we have our own organisations

The start of Idiocracy.
Or for court cases they’ll need a collection of “reasonable persons”
How does NIST ensure the particles in the SRMs haven’t degraded from the the initial values for old materials?
Proper storage conditions would help, but some substances, like B vitamins degrade easily. I imagine they test older stock against newly made material to verify before it can be sold.
just blend the old particles and powderize it
This is like a Human Archive. Archeologists are going to find this place in the future and have a mindfuck trying to figure out what the area was used for.
This is like the periodic table of everything that surrounds us, except it's not elements lol
NIST also played a pivotal role in standardizing internet communication protocols. Without them, the Internet would be a much more chaotic and much slower
@Jordan you seemed to miss the part about standardizing communication protocols. Which makes sense considering idiots like you cry government overreach at everything but can't get up off their arse to vote for someone else
@Brent Fisher I guess you'd like China?
@Brent Fisher They're the same thing
@Farrel Rafi dude stop being racist and dick riding me
@Jordan Give me an internet run by big government over an internet run by big media, any day.
Should there be a gathering of materials like the dust every decade or so to check in chemical and other differences to the environment over the years?
I love how passionate that guy is about his job. You can tell he loves so much about what he does, and he is so excited about it and it makes me really happy to see.
Despite how it looks like, and oddity that he is so popular, this guy exactly is desperate only for recognition and for all to think, that he is very smart and unique, kinda sickening
A lot of times he is proven to be wrong, but he never acknowledges that
And why some truly great creators a friends with him is also a mystery
Always quadruple check what you hear from him, that’s a very good chance that he talks total BS
@FlyveHest - Wait, was 'shelf' a typo or an intentional pun? 😛
@Daniel Z Yep, taxpayer funded salary working for the corrupt government. He could care less about all the crimes the government commits so long as he gets that fat paycheck. Typical of government employees
@Tucker Southard you could work for the mafia instead, same thing as the government
Uh, but it's all funded by violence and force and coercion, aka government.. why are you applauding this
amazing video exposing us to the people that do invisible yet crucially important work!
I think this might be your most fascinating video to date. Makes one want to write a story about it. Kudos.
Thanks for commenting/
Just makes me think that, in general, there's so many people with really deep knowledge and skills that are working away constantly to keep our world safe and operational. It's very useful to remember how we're all so dependent on people like this.

I am not a science nerd or in any profession that depends on this kind of information and I was fascinated and amazed by this information. Thanks for making this available to your average little old lady. We are never too old to learn.
I love your name! Lol
Worked at A Military Calibration Lab (PMEL) as a scheduler. Opened my eyes to not only Standards but how temperature and humidity in the lab is so important. Never appreciated prior to that as a Mechanic how much work went into that sticker on the equipment.
Read it too fast and got "humility in the lab" ... hehe that too.
Why would you work for one of the most criminal organizations in the world? For money of course, but you have no principles?
How often are these things updated? Because dust in our houses now is probably very different from 90s dust based on different microplastics, products we use on our bodies and furniture etc.
@mattg706 He may be talking about the particular jar. He also didn't specify that he wouldn't be able to find out how old it is.
I did find it odd too and still do.
@mattg706 That was specifically for the peanut butter reference which would not need to be updated as peanuts are still peanuts.
Its updated occasionally. I'm not sure how they decide the expiration schedule but the website shows House Dust as revised in 2018 and expiring in 2025.
I was really surprised to hear him say "i dont know if i can tell you how old this is". For such an extensive process it seems like such a small yet important detail to leave out when dealing with a lot of these things.
This was a phenomenal video. Thanks!

@LabGecko nonsense, it'll just take you a while out in the wild to find a semiconductor tree. At which point you're halfway there!
@Rob Woodring can I send it via HAM radio or its equivalent? That'll cut a lot of time off the objective. If I have to produce two display monitors, it's gonna be a while. :)
@Inverted Flow the good thing is that when the material scientist that works with semiconductor is using their computer for work, they might not understand fully how the Google Chrome software or any other work related software is working, but software engineer will!
@J Miller That's awesome
Yep - my father is a soil chemist that runs quality control programs for soil testing labs. There's way more of these labs than you think, because they're used by farmers to determine what kind of fertilizer to put on their fields (among many other things).
What's fascinating is that because the QC program is so large, the excess soil is highly desirable by labs to use as reference and calibration material for equipment.
And that's how he ended up selling buckets of dirt internationally.
I've been following your channel for like 10 years and this right here is a holy grail video. I have had this EXACT question (the one this video answers) in my mind probably since the age of 5. My fascination with Nutrition Facts on boxes has been life-long and I have always wondered _how_ they get that data, and _how_ they _prove that it is exactly accurate to what I am eating_ . And now this video shows me that it's because of a thing called an *SRM* or, *Standard Reference Material* ! Genius.
Many government agencies are less than worthless and people interact with them unwillingly(At gunpoint when you get right down to it.), but NIST is different. As a machinist, I've known about them for decades and regularly benefit from their work.
This is what happens when you use persuasion. Standards get made and people work as a team.
Agreed. By all means folks, have your gripes with the government but something like NIST could never come into being without a functioning, well-funded government.
Oh my, I love this video so much. I have long been fascinated and humbled by the standardization efforts in the world. ISO, ANSI, and innumerable technical standards, all of which probably at some point in their development interact with the tangible products NIST produces to actually substantiate their standards. These are the mechanisms that make modern society function. They are foundational to the quality, reliability, and consistency of almost every single moment of our lives. It would be a dream to contribute to that.
We want more on NIST!

I like how human civilization eventually came up with such a system. We frequently do not realize how amazing some of these quality of life things are since we're so used to it being a background part of our everyday lives (which is good)
@_Wayward_ I got a lot from the video.
Multiple examples of needless complication.
If you want to make peanut butter, start smashing peanuts.
Sell the products of your smashing efforts. Peanut butter.
End of story.
Hint:
50 lbs of shelled and skinned peanuts yields 50 lbs of peanut butter.
@1cont LOL is that all you got from the video? You aren't the sharpest are you?
@_Wayward_ only a sheep would spend a thousand dollars for standardized peanut butter.
@1cont some sheep forget they are sheep. Don't forget again
@_Wayward_ some sheep really think that the farmer created the hay.
I’m in my undergrad, and I worked on a project that was examining mercury deposition. One of the things that was done for the project was measuring certain samples we collected for mercury. Reference standards were used for that, we used soil standards. It was very interesting to learn about how important these standards are.
I am always happy to see that a branch of the government is efficiently doing it's work.
I don't know how to feel about the fact that this is a... poop-related work, though.
@Steven Liddicoat just like they did the FICO scored before Market Crash in 2008.
I’m pretty confident that a private company could still execute this function better than government.
@Shrek Eyes I wouldn't trust any company to do this however
Very rare for the government to be efficient

CNC Kitchen is a guy on Clip-Share who built a testing machine that works in exactly this manner, and shares tests of 3D printing materials and techniques so everyone can improve their processes.

"This is something that wouldn't be viable to make you peanut butter and jelly with."
Now that sounds like a challenge to me.

I'm a medical lab tech, and I find NIST to be fascinating. We use standards (we call it QC) to make sure that our analyzers and methods are working properly and giving accurate results so that you get the care you need next time you're in a hospital. Our stuff's not cheap either.
NIST is one of, if not the, most under appreciated of all US government agencies. I was lucky to be able to tour their metrology lab in Gathersburg, MD in 2007. It was just mind blowing.

As a metalurgical engineer, We use standard materials all the time. Typically, different grades of steel and iron to calibrate spectrometers for chemistry readings to verify the heat. Any sort of materials engineer uses some form of standard material, it's nice to see where they come from.
As a pharmacy student, I find this quite fascinating as we would learn of formularies and drug standards - and finally witnessing such an organization like this exists really broadens my horizons for how important "standards" are to the practice of various professions even non-medical ones, really!

@Veritasium.
Just curious how do they determine what chemicals or bacteria came from the human feaces. Since we use strong or mild chemicals to clean our toilets and some through away dead fish etc in the toilet which could also contribute to bacteria etc.
I am sure there is a way to exclude such sources, however cannot think how this is done.
For several years, I worked right across the street from NIST in Gaithersburg, but I never knew that they had a warehouse in there! I certainly am aware of what they're doing in general, but was completely oblivious of this. Neat!

This is one of my favourite videos of yours, ever! Soooo interesting, and I learned things I never thought about that now gives me immense satisfaction just knowing. Thank you, Derek & the wonderful people at NIST!
Do those standards include common, almost standard, manufacturing errors?
I would hope so. The point of a standard reference material is not to have a perfect material free of defects, but rather to have a material that has been analyzed so extensively that it can be used to calibrate measurement tools. So if I have a sensor that's made to detect a particular set of manufacturing errors, I callibrate it using a reference material with a precisely measured amount of each error. My sensor is accurate and calibrated correctly when it measures the same amount of error measured by a reputable source, such as NIST.
Didn't Veritasium already do a video about this place a couple of years ago? I remember watching one, and I can't think of who else would have done it among the youtubers I watch.
Edit: nvm it was Tom Scott

I used to work as a chemist in a materials testing lab, and we used NIST metallic standards constantly. Our machine shop even machined a lot of those charpy standards for NIST!
⬆️⬆️ look up my handle he sells all microdosing and psychedelic stuff 💊🍄🍫🍫….
Must be a really reliable machine shop.
@Smirnoff Jetski y u do dis
ok but why dont black people do this
I worked at a place called E.W.I.(Edison Welding institute) ours were made from plate that were fused with proprietary welding materials to determine whether or not it was an acceptable application for the customer. We also machined "dog bones" to test tensile strength.
my grandpa was an NIST employee but i don't think it had anything to do with this lol
I’ve worked at NIST and many other research labs ( university, industry, etc). Scientists at NIST are the most meticulous by far.
Thanks for watching Tell Hernandez ⬆️👆 I referred you to her she will introduce you to something highly profitable.....
I work in a hospital lab and we use standards all the time to calibrate our test methods and make sure they're running properly. It's interesting to see how the companies that make their calibrators and control material have to calibrate their instruments using a standard from NIST.

I work for a company that produces every type of analytical measurement instrument you could ever think of. We use NIST reference materials every day to qualify our instruments. We call them SARMs though, standard analytical reference materials. We use NIST steel spheres to calibrate our density measurement machines. They produce a great product, and are vital to industries like mine. Keep up the good work guys!
@ben let's say that you know a scale can accurately measure 100 lbs, 150 lbs and 200 lbs because you used only references of those three weights to calibrate it. Does it mean the scale can only measure those 3 weights? No, it means it can measure any weight between 100-200 lbs within a small margin of error.
@ben to expand on what James said, take note that the NIST rep said they take samples. Chemically those apples are very similar, but to account for those small differences that's why they blend them. That's why it's a "standard" instead of "chemical model of Granny Smith" apples. It's a baseline, nothing more, nothing less.
@ben That variation is irrelevant to the standard and device being calibrated. If I know my scale can accurately weigh an object to a very precise degree then it doesn't matter what I weight after that.
@• I love SARM's
somebody said SARMs? 👁
This is such a fascinating video.
It's oddly satisfying to know that this amount of science, analysis and 'know how' actually exists. I often question myself and everything, that leads me to wonder what 'everything' is in everything... lolol
"gut flora" is certainly a phrase i never expected to know about in my lifetime... cool that it's happened on my birthday, too.

NIST helps me on a daily basis just with its libraries for MS. it's great it exists

Working in the lab of a sewage treatment plant, was interesting for a while, but then became insanely boring, but one neat thing was the fact that the more accurate our scales were, and also our ability to dispense the necessary items for testing, the smaller the test sample could be, and therefore the less of those necessary items would be used as well. Our scale was so accurate that we could weight our fingerprints. We would have elementary school kids tour the plant from time to time, and we would pick one to pickup a beaker while we turned our back, then we could correctly tell them how many fingers they used to pick it up with. We did have to instruct them to use the pads of their fingers not the tips to make it fair, but as long as they played fair, we had a 100% correct “guess”, and the kids absolutely loved it. We also typically picked a kid that was somewhat socially awkward, which made them the big shot hoping to help them socially.
@Yeekthoven I'd say "carve that into a stone tablet and bring it to me on foot" but you can imagine how geeky the people how invented writing systems and stone tools were.
@A J Wright geeks don’t build the world they destroy it. All these technological advancements are leading to nothing good. We’re destroying our environments, atmosphere, bodies, and eventually our own species through weaponry or AI. All because “geeks” can’t resist biting the apple.
@Yeekthoven Nah, geeks helping geeks --- and the geeks who'll build the world, baby.
@A J Wright Dweebs helping dweebs😂
10/10 wholesomeness coming from a sewage plant 💕💕💕
The one and only government agency I can trust, as it always puts out the correct standard everyone else double checks and can tell is correct!
weird how incredibly important this is
When I was in the military, I used to work in calibration (AFSC 2P0!!!) so I knew a lot about the NIST tracability for our standards ... but all this stuff was pretty damn neat to see, and a side I never knew about.
I still have several empty steel NIST test dust buckets from my time at Dyson.

I work in an analytical lab here in Brazil and I use a lot of this peanut butter reference material as a quality control for mycotoxins, fatty acids and metal ions in food. It smells so good though! And thanks a lot for these people that work at NIST and make this reference materials. You guys rock!
@Bobson Dugnutt well that shut him up
@KairiRoseEquinote he didn't say it was a one stop town.
@Unified Theory of Life 3 floors is not a high rise so I’m not going to bother reading anything after that. Anyways have a nice day 😌
that's super interesting! I used to be a data analyst so all of this is so cool to me lol
@Unified Theory of Life There's a difference between radiant heat dissipation and kinetic energy transmission. It's the principle used in controlled demolitions of structures that were designed to withstand these heavy impacts. While a giant ~205000kg jet slamming into that building at 750km/h would only have generated around 7-8 giganewtons, the explosion of 90000 liters of jet fuel added anywhere between 70 and 150 giganewtons, which brings it to the realm of what is used to bring down even larger buildings. For comparison, the demolition of the significantly taller Mina Plaza only took around 6000kg of explosives, which was of a class that would have generated only around 50 to 80 giganewtons, barely over half the force that plane crash event generated. While the efficacy of force delivery is certainly much higher in controlled demolitions, it's not hard for 30+ floors of falling structure to make up for the rest, especially when structural integrity gets compromised more and more with each impact. Additionally, most demolitions prefer to go over the force requirement if possible and add more explosives / reduce section distance between explosives, not because there isn't going to be enough force, but that it's simply cleaner of a job when there's less structure to take impacts. I'm sure the fires didn't help things stay structurally sound either, but to be honest they may very well have been completely irrelevant at this point.
The structure doesn't have to be exposed to radiant heat, just vibrate enough to the point that it lowers its structural integrity so that it can no longer support the weight of what's above. Once that gives, impact force from the falling section will create further vibrations that further destabilize the structural integrity of what remains. If you're lucky, or unlucky in the case of demolitions, it stays standing. Most of the time, it does not.
On a related note, this is the reason why skyscrapers (and increasingly even mid-rise buildings nowadays) built on the pacific ring of fire (Japan, New Zealand, Taiwan) employ technologies which allow for the structures to take reduced vibrations from earthquakes. The main difference is the way the energy is delivered, with earthquakes predominantly consisting of maintained lateral forces, as opposed to one big delivery from an event like 9/11 or a controlled demolition, but earthquakes can easily deliver enough kinetic energy to destabilize a building.
Wow never realised peanut butter's such an eye hazard 😂
I love this! I think in a different life, I would have liked to go into the sciences as a career. Unfortunately, I am terrible at math. Even a science/research that is seemingly "mundane" like this is very fascinating to me. :)
super intresting! thank you very much for this video!

I learned two things today.
1. These people's work is definitely underrated. Now I understand how some foods and products can exist for years and taste the same. Consistency is key and these people are definitely helping with that.
2. I'm never eating peanut butter anymore. 😅 Never again.
Most bigger peanut butter brands do not contain aflatoxins in any major amount and there is no need to fear for liver cancer from eating most peanut butters in developed countries. There's a bit more that can get by with smaller brand natural peanut butters but again, not something to really worry about. On that note, aflatoxin is a toxin found in molds from peanuts, corn, other grains and in less developed countries that make peanut butter in less sanitary conditions, more may slip by. Derek makes purposefully misleading comments like this all the time.
@Turnt SNACO Yes
don't worry, if you eat standard peanut butter, you will produce standard sh*t, assuming your body is standard :)
What do you mean? I'd really love some peanut butter right now
Possibility of toxins aside, peanut butter is one of the most calorically dense things in your kitchen
Unless you're on a bulk, you shouldn't need all those calories anyway lol
Hi Derek! Awesome video as usual. I appreciate that you expose me to topics I never would known about but still interacted with. Can you cover the concept of "targeted ads", "online reviews", "the high income job market", "the need for pillows", "visas/passports/international boundaries/citizenship" ? I'd love to see what side of these topics you'll uncover!
This is really interesting. How very important this is. Just amazing. Thank you to everyone working so hard at NIST.
Truth in a bottle? Sounds like canned knowledge. The Akademiya has picked up some interesting new hobbies XD
It’s fine, it’s just the creative inventory
Don’t the samples degrade over time? E.g oxidation of the fats in the peanut butter
I knew that the NIST was a thing, but I didn't know how they provided the information to companies and researchers. This is so interesting.
A great example of one of the millions of the things the government does, that no one in the public thinks about but is critical for our daily life's.
This was all very interesting, but now I just want to know how long the mixing period is for each standard unit. Is the mixing period for house hold dust the same as peanut butter? I'm assuming there is some sort of standard with the viscosity of each material. What other secrets are they hiding in these srms?
This is so amazing.
Mundane but so perplexed at the same time. Kudos to the team at NIST & to you for bringing this to light.
Does it actually affect the world, or just the US?
Thanks for watching Tell Hernandez ⬆️👆 I referred you to her she will introduce you to something highly profitable........
I think this is the closest to get to the SCP foundation in real life.
I sometimes have this half philosophical thought-half irrational fear that nothing is ever reproducible but this kinda changes that. pretty cool
@goodiesohhi I agree. But those are probably fighting words down over at NIST.
They most likely go past significant and take pride in doing it.
@bill ted Everything has a margin of error. We cannot get down to a discrete level of detail. We don't need to though. Significant Digits exist for a reason. It only needs to be good enough.
Remember the white paper he showed . It said even NIST has a margin of error.
If i had herd about this 25 years ago, this would be my dream job. That sounds fascinating and rewarding.
Government bloat. Go get a government check or EBT. Same thing.
I literally drive by NIST like 8 times a day as a Paramedic in the area. Never knew what they actually did there.
Wow I would love to work in this warehouse. I'm glad we have a place like this making sure standards are kept at a certain level. Thank you NIST.
Thank you for this. I literally had no idea about NIST and the awesome stuff they are doing
Handling a 50 micron spherical ruby single crystal from NIST to calibrate X-ray diffraction equipment has been one of the scariest experiences I ever had as a researcher... I had nightmares about dropping it on the floor and losing it
@Butters Da Baller Fun fact: the head gap on an audio cassette player is not much bigger than 2 microns, possibly even smaller. A human blood cell is more than twice that in diameter.
@Fred Werza the Phrozen Sonic Mini 8K has 22micron XY resolution for less than $500. It’s remarkable. The biggest limitation holding 3d printers back now is chemistry and time.
@notahotshot I'm a technical person, been using PCs since 1992, so I'm not to be trifled with on these matters
@Fred Werza
If you don't know what you're talking about, on the topic of 3D printers, just say that.
@David Pawley I just can't wrap my head around how a sub-$1000 printer can have 25 micron accuracy --- that's half the width of a scalp hair!
Google Domains is not available even in all EU countries. 💩
I always wondered how society got by without places like this, and apparently it turns out they do exist and they're exactly what you'd imagine. A bunch of engineers standing around and saying, "This is standard."
The answer is, the world got along absolutely fine, if not better since there was no resources wasted
Amazing I live in an era where I can watch content like this for free. Thanks, mate
Thanks so much for highlighting NIST!!! Standardization is so important and under appreciated!
I'm curious how many people work there. You'd think it would require a whole range of experts from different fields to standardize such a variety of materials. Perhaps it's not as difficult as it seems in many cases but I bet they have different people for things like industrial materials and microbiology for example. Fascinating
Dr. Steve is very likable and passionate about his job.
What I find amazing about these videos is how US government agencies affect not just the lives of Americans but people around the world. From NASA to NIST to the CDC, etc.. it's truly amazing how these agencies affect people around the world directly or indirectly.
