all right should i introduce myself it's recording hello everyone my name is noah and i'm a chemist i'm very qualified because i'm a chemistry major i am currently taking biochemistry inorganic chemistry 2 inorganic chemistry lab and i've already taken general chemistry of organic chemistry 1 organic chemistry 2 organic chemistry lab analytical chemistry instrumental chemistry and i will in the future take physical chemistry i also work in a chemistry lab uh where we do analytical chemistry and i have just been accepted into the alpha fold two teams where i chemistry chemistry chemistry chemistry chemistry chemistry chemistry
chemistry chemistry chemistry chemistry chemistry why don't you come see if you're chemistry with some [ __ ] first [ __ ] are a mixture so i don't roll with that i only i only roll with like pure compounds okay so also on the couch we have phoenix hello chemistry qualifications biology i've taken biochem i've taken iv chemistry which i mean at this point is becoming less and less relevant um what else have i done i've taken organic chemistry baby orgo i've taken a bridge orgo and orgo one for some reason yeah i do chemistry what's
your chemistry qualifications gen chem we're go biochem and that's it [Applause] and there's others but they are important because they're not chemistry people dr stone this is real chemist who reacts to dr stone so noah what is that machine it might be an nmr machine because the nmr machines do look wacky like look at how wacky these look like i would believe it if like this was nmr i wouldn't put it past them to have an actual machine there yeah that's you can put pictures of nmr but it also looks wacky yeah and it's even
higher yeah yeah it wouldn't be fumey it's not it's fake chemistry it's a bad shower this sounds japanese oh it's real chemistry class is always like oh [ __ ] if you have a mixture you failed you need to purify everything you need to recrystallize you need to do a distillation to make it so [ __ ] pure is this why you're only holding 40 is this why you're only horny for compounds yes yeah wait so how do you predict that they're going to get the alcohol the ethanol fermentation easiest way yeah and how does
it how do they do that how do you ferment well basically all you need is a yeast you can use other stuff but traditionally it's used with yeast and it just needs like some starch like some sugar right so they're probably going to like grind up some berries or something and give it to yeast oh yeah and ferment it why is nitol so so cool and epic like night that's a good question the real key to being a chemist is reading wikipedia articles for chemistry nytol in popular culture oh my god is it dark is
it darker stone it doesn't say why it's used for etching though like why it's good at ethnic etching it just says that it can explode cool for all you kids out there interesting they didn't show the yeast though yeah yeah yeah just onto just like they're just hoping to just cook because if you just do that yeah but there's also a chance that like something else can go in there and like produce like neurotoxins but i guess they don't yeah this is what we did last semester shut up it's been like at least six months
right because it's winter i mean look at his beard it's like mine yo literally doctor wait what's the other guy's name please the other guy's name actually dr stone or is it just like yeah he's a doctor could you could you guess what the dr stone actually refers to this yes the stone people now [Music] we gotta show this to like elementary schools [Music] what is the likelihood that that tree manages to stay alive for that long for how how long has it been it's a camper tree it's 3 700 years most trees can't stay
alive i think like the oldest tree living now is like around that age so probably not unless it was i think joshua trees have the longest sun trees or one of the longest live trees there's a 700 year old camper growing in the middle middle of kaiashima station yep that's not 3 000. that's not quite yeah yeah the oldest tree alive uh is a bristlecone pine uh and it's around five five thousand years old so like it's possible to treat but definitely not that species of tree what's like the main reason that trees die is
it like wow what are the reasons it's actually a biology question natural disaster is probably a big one predation diseases do they have to i mean what natural disaster can be worse than this they only divide at the end of their buds the rest is just the cells elongating the rest of their growth yeah yeah oh well they they divide from the middle as well they have the what the mares and the meristem biology 1108 come back to me cambium cambium they divide from a ring of cells in the in the trunk called the cambium
and that so they have like horizontal growth and they also have vertical growth why why do plants age i know like there's like a height limit to trees but minecraft i have an insight as to why they might have chosen a camp for tree apparently in like buddhist mythology there was like this um famous priest and like there's a statue of him that was like well preserved within a camp for crease i think it might be another symbolism well symbolism isn't science and you organize i have a question though in 3700 years don't you think
a natural disaster would have taken down the tree yeah because also like just like chance of like some physical harm having lightning strikes because we saw it was like in an open field you know so one of the the least realistic aspects of this are the what kind of tree was it cantha a camphor tree living for 3000 years how about the people turning to stone oh no supernatural disaster what's the science behind it although it's not strictly scientific i notice that um like it's just implied like it's just supposed to be like accepted and
implied that like we should like if you're in this situation like it would be morally right to like restart humanity right even though like we see yeah exactly we see like how without humanity like nature recovers and like everything returns to its natural equilibrium because as a chemist the first thing that you learn is you should build bombs and kill people um it's not just like humans should continue right they haven't like explicitly said it but they implied that like humans should um like like we should revive everyone and continue the expansionist like philosophy of
the modern human era there's they could also just like revive some people revive the cool people you know yeah anyway i think the episode the episode pretty good not enough chemistry for sure you're gonna get so much more of that i can't just wait until they make uh antibiotics antibiotics why do they synthesize them or do they like got me characters i really wanted i i had heard like that it was like a chemist that was doing it i really wanted like the chemist to just have died and it was just like the one guy
who like his love like was the only reason that he survived and then he had to like learn chemistry afterwards wow a textbook that just meet propaganda it's fine we've given them a 3700 year cooldown i did learn in my microbiology class that aldehydes are used as antimicrobial agents yeah formaldehyde loser aldehyde smoke i there would probably be aldehydes in the smoke but i don't know if the reason why smoking meat cures it is because of the aldehydes like there's like just so much stuff in the smoke that like um kills stuff somebody's dying something's
dying it's a combination of i'd say at least perhaps the aldehydes but originally i think it's like desiccation and removing the water activity dehydrating dehydrating and even just like carbon monoxide it's heating you know heating pasteurization only goes up to like 55 to 65 degrees celsius but not like super eating i'm not like cooking it yeah it's kind of impossible to eat all that fish yeah much for three people have you seen matt stoney okay buddy [Music] calcium carbonate as the most important thing after etching fluid that's really the only other chemical they made i
mean it's not stone age tools stone age tools so it's got fire taken care of yeah fire taken care of obviously so it's a weak base that's used for many things i don't know how they're going to use it i mean what does that create then i guess is the question well calcium well carbonates a buffer yeah it's a buffer yeah so like but like i but yeah their body buffers their own ideas like when i was watching this for the first time the first thing i thought of was concrete but oh that seems a
little further yeah but maybe like for a preservative i guess but they already have smoke oh for fertilizers [Music] hold on hold on like i'm pretty sure you need a stronger base to make a saponification reaction like you've got calcium carbonate you got sodium carbonate they said they're taking the sodium carbonate i think they're equally as strong bases ph eight to nine and then we need to look up the pka of calcium carbonate well sodium but they're the same because it's just that in that case why did they not just keep on using the cells
why didn't they have to go do you need the sodium ion we learned about it we learned about the spot occasion in orgo and there's no sodium doesn't participate in the mechanism do you remember that yeah okay so why is the highest component of detergent sodium bicarbonate instead of calcium bicarbonate do you think this the sodium axis of preservative i don't know oh maybe because this all but you wouldn't need that for so yeah yeah i don't know hold on maybe so that it's more antimicrobial because they're looking for a soap not just to wash
their hands but to make sure there there's no bacteria well if anyone's wondering the uh pka of carbonic acid which would you know you just react water with carbonate is 10 which is and you only need eight for some quantifications so it is possible for i i forgot to say this about fertilizer it like so they're just using it to balance the pa ph but that only matters if you have acidic soil right i don't know what kind of soil that region yeah but the calcium carbonate comes from shells which aren't they similar to bones
they have bone meal in minecraft [Music] [Music] is saying if you bring everybody back there's going to be suffering yeah and senku's saying if you don't bring everybody back they're all going to die which okay yeah but i think there's also a middle point where there's enough people from everyone to survive but not all the bad people that will take over everything who draws the line though i guess i mean just the three of them yeah yo this is literally an allegory for social media three white guys that know how to code white japanese they
just look white because japan likes white people calcium carbonate i was wrong this can be used for supply but my favorite reaction of all time which if i would ever get a tattoo it would be the reaction um calcium carbonate you have to put this on the screen so they understand calcium carbonate um plus heat uh creates calcium oxide and co2 right which is the reaction that happens when you create concrete right which they're doing like mortar right they're using calcium carbonate to create it but co2 co2 is cringe wait well you said this is
your favorite yeah it's my favorite because it represents the cost of um like it it shows so succinctly like the the cost of industrialization do you know the fourth use of calcium carbonate let me see if i can figure out so concrete soap well soap is that's like so broad though because you could use it as a base and bases can be used as like so much so if if it's just like it's used as a base in this reaction that doesn't count there's a fourth [Music] what can calcium carbonate be i mean yeah as
a basis ah corrosive i honestly don't know of any poison or or uh i forgot yeah and then also um like erodes with water so so then why is that still standing oh well like slowly right so like enough to like leach into the soil and like poison the plants but not enough to like you know yeah heavy metal ions like copper are used to as antimicrobial agents and they're sterilized actually but they can't be used in situations where a human has to come in contact with it because it's also poisonous for us my mother
your mother you better answer your mother should i answer them [Music] this man's gonna drown [Music] yeah ethanol and nitric acid probably not gun powder [Music] is that accurate to how people make on powder nowadays i actually look this up not because [Music] you need charcoal which is easy to get you need sulfur nitrate because you know for any amateur bomb makers out there the hardest part of that to get is actually the nitrate i feel like not the sulfur derive it from nitric oxide the nitric acid it's pretty close to nitrite d can you
just oh you use the calcium carbonate to deprotonate the nitrate nitric acid into nitrate god damn this [ __ ] is buzzing okay so you got the hardest part the nitrate and what else you've got yourself now let's see if they're accurate and they make charcoal to also make the powder immediately [Music] literally anything for views literally so this the fourth use of calcium carbonate was just from its basic properties so it doesn't count just like i said raspberry pi cs we are now a danger to this uh residence hall for how much information stop
doing science it's too dangerous i'm gonna drive to the beach and pick up some shells i mean are you enjoying the show and stuff yeah i'm enjoying the show yeah is it and you would say it's uh chemically accurate was it were there any chemical inaccuracy i feel like the biggest chemical inaccuracy is probably the etching process which is integral to the plot because like it's within the it's i feel like that part is a bit more fantastical but otherwise good chemistry yeah acuity 3d that's how we have to end it can you tell the
camera to like uh subscribe and uh the other thing coming yes that's it please like subscribe and comment to nico cabo autocabro that's not no please don't that's not my channel this is not your channel nico avocado yo what channel is this then god dance yeah this is actually a mukbang
