September Video: Concrete and other special interests!

Man, I am bummed you couldn't do materials engineering! I got my undergrad in physics and transferred to a nearby university for grad school in MSE. I guess that just goes to show you stuff. Also concrete is sick and I was totally ready for a concrete video.

I would gladly listen to ninety minutes on concrete. I'm a civil engineer and I only mind of know how it works.

Regarding chiropractors, I agree that it is very dangerous that people that aren’t medical doctors can practice on people, but I do have a positive story to share. My little brother was seemingly late developed as a child, he didn’t speak and he was crying way more than usual for his age. My mother (who is alarmingly new-agey in general) took him to a chiropractor she sees regularly to this day and he did his neck-cracking thing on my brother. Within days he was a normal child! I do believe that in some cases there are real use-cases for chiropraxy (is that a word?). Some chiropractors are also licenced physical therapists, which I believe is a good sign that you’re not dealing with a charlatan. Oh and we are in Europe, so we have health insurance and go to regular doctors.

I'll offer a concrete anecdote, a decade and a bit ago, I was a card carrying member of the Oil & Gas sector. We needed an anchor that would dissolve in seawater at 4C in X (I think it may have been something on the order of 1-2 months), so that our sensors eventually would float to the top of the ocean. They went to the local research org, and asked for help doing this. They were supposedly very excited, because normally they were tasked with the opposite, finding something that lasted as long as possible. Anyway, it's a story that stuck with me, and probably will.

Messages to / from aliens (if ...) : I don't see how we could exchange some type of knowledge or tech. But the one thing that would actually mean a hell of a lot would be simply to know, with proof, that there is other intelligent life out there. Just to know that we're not the only ones with the responsibility of carrying this torch. Because I'm not really confident that we won't fuck it all up somehow.

Section 31? Angela please. It's the worst Star Trek thing ever. Ever ever. Most of the new shows are really different than all the other new shows. How are you gonna know which ones you like without giving it a try? Prodigy is so lovely, although I hope they continue it somehow. Lower Decks was kind of really self-referential humour for supernerds, but the tone is really light. Nothing is serious. Don't let Picard kill it for you. That power is not in the hands of that show, this power is in your hands. You can decide that you don't allow Picard to kill ST for you. Just decide that. Just put the Star Trek stuff in a 3rd channel!

Angela, your Picard video is AWESOME! I'm not an expert on any of the technical stuff of video production. If you want to get into this more, do it, but not because you feel bad about the quality of your current works! And if people who came here for the Picard video (like me) but don't like the rest, here's the golden key: LET THEM. I got that from Mel Robbins' podcast. She calls it the "Let Them Theory". I'm not joking. Check it out, it's awesome.

There was one bit about roman concrete that sounded like a piece of actually new information. I found it on the wiki page: "Research in 2023 found that lime clasts, previously considered a sign of poor aggregation technique, react with water seeping into any cracks. This produces reactive calcium, which allows new calcium carbonate crystals to form and reseal the cracks.[16] These lime clasts have a brittle structure that was most likely created in a "hot-mixing" technique with quicklime rather than traditional slaked lime, causing cracks to preferentially move through the lime clasts, thus potentially playing a critical role in the self-healing mechanism.[1]" (https://en.wikipedia.org/wiki/Roman_concrete#Material_properties)

Not sure if you were really asking, or just used that as an outlandish example, but John Smith in Romania would be Ion Popescu probably - Ion is a version of John and Popescu has a mildly interesting meaning "son/daughter of the priest" since in Orthodox Christianity priests can marry (have to marry before they are ordained, they cannot marry after).

Hi Angela! I’m a chemist in the pharmaceutical industry, but with a related special interest in sand. I’m not sure about how the environmental impact for concrete production is determined, but I believe a substantial portion of it is due to the production of quick lime (CaO) from calcium carbonate by heating. This releases a mole of CO2 per mole of product. Your discussion of the failed roads in Iraq mentioned test beds. I had to work with ASTM test sand in the course of my work. I forget the exact method it was used in, but the test involved making a standard cube of concrete from this sand and other specified materials. Neat stuff!

I'm late. But I found your channel because of the star trek video, watched a bunch of your other videos, and am a structural engineer that designs water/wastewater concrete structures so I'll listen to that concrete talk all day. Though I will stop paying attention when you get into concrete finishes and all that, no one cares how nice the finish looks on your 5 million gallon sewage tank :P

Tell me more about the "guillotine solution": a fellow fan. Waiting for the long-form concrete video.

I like to think of fossil fuels as “Jurassic chicken soup”.

i'm so sorry i skipped the concrete portion. loved the video though

I have so much astigmatism that I once forgot the Youtube quality to 480p and now I just keep using it cause compression algorithms have come a long way and I don't care about the difference. I mean I do wear glasses but I just don't care. I've gotten used to a blurry world. Anyway, I joined here because of the concrete video.

Finally got around to watching this. Learned *so much.* Want to add: have you heard of Project CETI? (Yes, they went there) They're doing a lot of research attempting to decode Sperm Whale language. There's also a separate group that carried on a "conversation" with a Humpback whale. If I'm understanding that paper correctly, though, that dialog basically amounted to a crank call with the humpback disengaging at the end by figuratively flipp(er)ing off the researchers. Links: https://www.projectceti.org/news-research-insights#publications https://peerj.com/articles/16349/

Another vote for more concrete content. Here is a little concrete trivia...1) In WW1 & WW2 the US built some cargo ships from concrete as a way to alleviate a steel shortage. Not only did these ships not immediately sink to the bottom, but one even supported the D-Day invasion 2) the average front load washing machine has a 50ish lb. lump of concrete inside it to balance the motor.

I appreciate your perspective that climate change policy aimed at depriving the developing world of basic infrastructure is deeply unjust/unacceptable and that guillotining billionaires (or at least diverting their resources toward real and equitable solutions for climate change) is the way to go. I realize you are probably not trying to ruffle the feathers of your broader audience, which undoubtedly includes vocal capitalism stans, or be dismissed as a "terminally online commie," but I do want to encourage you and other creators, in whatever way you feel comfortable navigating the space, to voice these sentiments more. I just joined Patreon after watching your video on the top 10 things physics has done in the past 70 years, but my political brain is always sarcastically narrating how "ackshually Elon Musk [or other billionaire] is responsible for [insert physics/chemistry/biology/medicine breakthrough here] because without their vision, leadership, and capital, it would never have happened!" I would love to see a video where you talk about how basic science research is funded, and how often startups are spun off by university research departments (and often bought up by large corps) rather than billionaires like.. directing their little science automatons they own to create a brand new revolutionary product like lasers or cancer immunotherapy. So glad you're in this space, dude. Also, your Picard critique is spot on.. so disappointing.

Hi Angela! (since you said hi in the video) As another kid that grew up with Mythbusters and How It's Made, my brain is primed to readily accept random concrete engineering information, so I'm all for it! I get why you might not be confident making videos about technical subjects outside of your field of expertise interesting though. Maybe you could differentiate your special interest videos, either in groupings like this or perhaps on your side channel? You could call them "I'm not a ____, I'm a physicist!" (I *might* be a little salty having watched you rhythmically disclaim "I'm not a doctor!" in a medical pseudoscience video while never completing the punchline. Much adhd anxiety) ps: I thought the Star Trek video was great and never even noticed a quality change, even though I had you up on the TV. I think your combination of science communication skills, stream of thought humor, and apparent enthusiasm are what has drawn your audience. While production value is cool and all, we can already appreciate the knowledge, love, and authenticity you put into your content. So... try not to sweat it too much I guess? (I'm something of a subject matter expert myself as someone who found you randomly through a sci-fi book video a month ago on your side channel and is now on your patreon because they're starting to run out of content) pps: Every Angela I've met hates Angie (I'll ask if someone likes a nickname after I know them awhile, since people often introduce themselves formally). I blame the Rolling Stones.

Jokes on you, I'm all for learning about the material science of concrete. And other things. I come from a more practical background where family and friends are in the trade. So, it's one of those things where I see it and things like it all the time but haven't heard the science behind it.

I watch a channel called Essential Craftsman for the construction work I don't know why. They have a whole series on building a spec house which includes a lot of concrete work as well as several other videos where concrete is poured. The things (chemicals, physical) they do to the surface to achieve certain textures and looks is really interesting. Highly recommend you find those videos at least to watch some high skill concrete trade work!

I thought the Star Trek video was great! It made me discover your channel and I thought it was so great I started watching your other videos and now here I am. Once upon a time I studied chemistry, and while I never finished because it turns out I didn't have the patience for quantum at the time, it's kind of nice to get reacquainted with hard science topics and the physics I had a hard time with in college.

When you started talking about sand in concrete and were feeling bad for going on about it, the only thing I thought was: The sand people are easily scared. But soon they’ll be back, and in greater numbers!

GIVE US 40MINS ON CONCRETE!!! Or at least give us links to your fav vids on concrete 😝

100% here for concrete. Back when he was a consultant, my friend would go to an annual conference called World of Concrete and it always sounded so cool that there was that much going on in what seems like a very mundane thing.

I would listen to 40 mins on just concrete!

Re: names - why is "Sasha" a common "familiar name" in eastern European countries?

My family owns a concrete construction company (we place the concrete in private and commercial buildings, we don't mix it) and even though I'm not in the business, I grew up pouring concrete. I, too am interested in whatever you have to say about concrete!

If you're recording in 4k and it is exported from your editing software, I'd check the settings of FinalCut before you export it to the final video

I think all of it is really interesting! I am very interested in concrete, too. Joys of homeownership lol. Btw, I loved your Picard video. I kept falling asleep instead of watching Picard and your storyline and the alternate was better than what I had going on lol. I’m sorry you’re feeling anxious about your channel dying but I’ll keep watching as long as you post videos because you awesome ❤️

regarding the video quality… “It’s fine”. Thank you for talking about concrete, now I’m craving even more Dr. Collier’s Concrete Content™

this was a fun video :) during the concrete bit angela said "everyone's roman empire is concrete" and i found that funny and for that moment my roman empire was concrete too. i regret to inform you that there are animal chiropractors, and that they make videos on youtube. it's the worst. also seconding the epistemology type video. i was the one that recommended Inventing Temperature, which i guess Angela hated. It won't hurt my feelings to hear why, and i'm really interested in fact to know why.

VIdeo shows up for me in YT as 1080, not sure what's the problem, I don't think YT likes 4k too much, I guess content might be limited there

I wouldn’t feel too bad about the video quality tbh. Easier said than done, but there was a major decrease in price of lighting and mics during covid and that changed a lot. lmao. Everyone started podcasts and streaming ! I think a range of audio and sound qualities was more normalized. A lot of creators I watch don’t have “professional” equipment. It’s usually all done in the staging and processing.

I would totally watch a full video on any special interest! It just feels good to listen to someone be excited about a subject. Also, anyone interested in what would happen if we found an alien signal at Arecibo should read The Sparrow by Mary Doria Russell!

I work in a private school with kids starting at 4 and I am tasked with entering student data. Currently every other boy is named Oscar. That was an out of fashion name when I was young. One thing I found fascinating about names is the Swedish naming convention of tilltalsnamn. You can have multiple first names, no middle names, and the name everyone calls you isn't always the first one listed it's the one you put an asterisk next to on your documents. Or hyphenated first names, that's interesting too.

I would love a deep dive on names!

RE: previous video - I would LOVE to hear you talk about epistemology, even if it is inspired by a youtube comment.

PS - I'm a data guy. I love codes. And I'm finding scales to be really interesting these days.

Ummm... I would love to learn more about concrete. So... Play on!

Others have probably said this already but you should start a podcast!

I really was into the concrete topic and went "awww" when you interrupted yourself, I'd love to hear a longer form of that again :)

I have never seen a Star Trek episode or movie. And I definitely watch Angela's almost-four-hour video about Star Trek. I would love to see deep-dive videos on any of those special interests. I'm still waiting on that promised video about banning gas-powered lawn mowers. Actually, start that video ranting about lawn mowers then halfway pivot to why do we even have lawns and also take the HOA police to the guillotine. Personally, materials science is something I would LOVE to know more of, since (IMO) that's stuff we actually interact with every day. For example it's kind of fascinating to me the fact that in combustion engines, the moving metal parts actually never really touch each other, there's always a thin layer of oil between them. Also, how does thread-locker paste work? How is some paste going to prevent bolts from coming loose? Going back to cement/concrete: what is going on there that as long as you keep it revolving in that big tumbler it won't become solid? Anyways feels like I'm rambling now...

I think you're unnecessarily worried about the technical side of your recording. Watching/listening to you talk about whatever probably isn't everyone's cup of tea but I happily pay attention to most of what you record. If you wanted mass market appeal, a cartoonist and editor would help, but that'll be a production. Consumer protection re: medical is a big deal and a bottomless pit! Also kinda extends to the crypto gambling boom and MLM stuff. The US just loves markets where sharks are free to feed on the general population, caveat emptor is the whole policy. It's giving mirror universe

My partner has already made me sit through a treatise on why Roman concrete is superior to modern concrete (she would LOVE a full video on concrete from you). I feel like my body and brain are ready for further information. 🌋

No matter what video you make Your amazing personality will always carry it more so than the content Keep up the great videos you make 😀👍

If you want help troubleshoot your video woes I'd be happy to help. I used to work as a VFX generalist and later media systems, I know a lot about technical and artistic video stuff like you mention at the end.

At concrete and climate change, I'm of the same opinion. You can cut the CO2 down partially with not using gas for the heating and the naturally occuring CO2 is a great candidate for direct carbon capture at the plant. Something that many concrete companies are actively working on. The long term solution is still in material science imo, there are some very interesting substitutes in development but introduction of those can't be rushed. Its such a saftey critical material, that we know it so extremly well is a big factor in its utility.

"I'm not sure if you want to listen to 40min about concrete". I think you are still underestimating your viewers lol

I'm a vegan for climate change. I hope it helps. I'm a new subscriber. It's funny because I watch a lot of science videos but the algorithm never suggested your channel until the Star Trek video. So I went to your channel and watched some science videos. (I did watch the Star Trek video later).

i have a feeling your worries are kinda misplaced: make the videos you want to make and people will watch them, maybe not the same people all the time but like, probably, to be honest anyone who gets butthurt about what you post or demanding or mad or whatever should be ignored also this was in 1080p for me (i noticed the outfit changes in the Star Trek video! i didn't comment on it tho because i watch YouTube videos on my TV, so this is maybe like a tree falling in a forest with nobody around…)

If you hate your name, you can change it. You can hire a lawyer to walk you through it if you want, but your state / city government should provide the info if you want to do it yourself. I just changed mine and the hardest part was just waiting for the court to get off of its collective ass and do something.

I was really getting interested in the grain size discussion and then you cut it off. :-( Seriously, your presentation style makes just about any topic interesting, even if I wasn't interested in it before. And I can relate to the "unwanted nickname" thing. My given name is August and I absolutely detest when people want to call me "Augie".

Really enjoyed the concrete part (I am also a civil engineer and therefore not normal).You are absolutely correct about the media blitz on Roman Concrete every couple of years, and it gets pretty frustrating bc often responses are just like the people who say "No real physics has happened in the last 50 years" except it's the last couple hundred. Like yeah, Roman concrete is great and we are still learning more about it, but also, we have some incredible concrete now that they were not even close to back then (like concrete that floats).

I think you've gathered a solid audience for you content, it is more about you making videos you're passionate about than the subject itself.

My friends and I keep a list of the worst names we’ve ever encountered here in Utah. I will absolutely share if anyone wants to read it. 😂 Just as some interesting data!

Loved the concrete part! It was interesting :) Normal person here.

enjoyed the concrete part. have you ever mixed and laid concrete? fun stuff.

chiropractors can, at times, be useful. perhaps much of their work is something of a con, but some of it is of real benefit. i was sent to one (my choice) by a physician and the chiro fixed what ailed me. happened to a friend as well. never went again.

favorite phrase: "billionaire guillotine."

Dude, I don't remember anything being off in the Star Trek video other than it being 720p. Points on the show, pacing, lighting, costumes. All great. I mean this as a compliment, for a moment halfway in, I thought I was watching a Jenny Nicholson video. So don't sweat it! And I would absolutely watch a 3 hr lecture on concrete.

Good take re: climate change and concrete. We don't need to ban concrete or personal ownership of cars, we need democratic workers control over industry and the economy. No more billionaires! Great video, as always ! Cheers du Montréal !

I was fully engaged with your discussion on grain size when you cut off and changed subjects. I was ready to learn more about concrete. Replaying that part at the end with crickets was a good joke, though. I laughed.

I think people feel some genuine relief going to the chiros in the same way people feel good when cracking their fingers. Cracking your joints releases endorphins which makes you feel good. That's all chiros do. But it's only temporary and certainly doesn't do anything to fix whatever the issue was.

Maybe we should ask various indigenous linguists how to play phone tag with aliens...

ProZD already knew how Angela felt about concrete: https://www.youtube.com/watch?v=4ZK8Z8hulFg

let's all keep on track with this "billionaires on guilotine" idea!

I just saw a bubble chart of the occupations of donors to Trump vs. Harris, and Chiropractors are solidly Trumpers whereas everyone else in medicine is blue. Not saying Chiropractors are doing medicine but you get what I'm saying. This is just further evidence that Chiropractors are doing a thing along the lines of a Facebook post that gives medical advice. Also I had one of those "How to Survive Everything" books where they go over step by step instructions for surviving extremely dangerous but unlikely situations like shark attacks. It was written by a former Navy SEAL who I'm sure is pretty right wing and the part on airborne global pandemics was just like "stay home, and if you can't do that wear a high quality N95 mask and failing that, a surgical mask, and watch out if you order a pizza because that guy could get you sick, the whole thing should last about 2-4 weeks." It's illustrated, so they show the guy with the military buzzcut ordering a pizza and what proper masks look like vs. a bandana. It's literally three pages and we couldn't manage to communicate this information.

Two things. First, I'm constantly surprised how versatile these videos are. The Star Trek video is definitely not my cup of tea, but I see some parallels with Mr. Plinkett's original Star Wars review and also with Jenny Nicholson. So I'm not surprised the crowd yells for more. Second, I also must admit as a doomster I really enjoy these little interspersed comments about the lurking climate cathastrophy. This is something I never would write long comments about , but it's a great another layer. Personally I think the conclusions in the first edition of Limits to Growth are still very valid (this is the only excellent edition by the way). CO2 is the greatest dissipative waste by weight of industrial societies, so no wonder that he is the one who is causing problems first. Climate is just an accidental messenger of a deeper problem.

Mentioned here a couple times as well, but sharing things that you are passionate about is what I find important. More hot mineralogy talk...

OMG, you didn't even mention vibratory compaction!

Chiropracty is a first line treatment within the Veteran’s Administration medical system. Unfortunately, it’s here to stay.

Speaking of the 'cosmology crisis,' I saw a new (I assume) article headline stating that the widely hyped anomalous JWST observations were just (somehow) erroneous, and don't require throwing out all of cosmology after all. How surprising. :)

In Russian, first names come in three forms: formal, familiar and intimate. Example - Ivan, Vanya, Vanushka.

I agree with you about Chiropractors. Some "patients" have died from "adjustments". Same with acupuncture. Same with homeopathy. And it's not possible to "boost your immune system" except through sleep and vaccines.

Given the time involved, we should ask archaeologists what to put into alien messages. Like what would they have wanted Rome to say to us when they sent it from 1600 years ago?

I'm so glad you mentioned medical misinformation! As an M.D. I always talk to people about pseudoscience and misinformation in medicine. It can be a very heated topic because people have different experiences, from literal fad diagnoses to those who take advantage of disease processes that naturally get better on their own (very easy to get someone to believe that your sham treatment worked). I've found two things that are very hard for people to accept: (1) you can do everything right and still get the disease, and (2) some things do get better on their own. An excellent quote from Voltaire is: "The art of medicine consists of amusing the patient while nature cures the disease."

I never saw any child in school get teased or mocked or ostracized for being athletic, but gee, did anyone else on this Patreon get all of that for being smart? Adults tend to approve of kids doing well in class, unless you get a teacher with a personality disorder, but the other kids in this country seem to pick up real early on our culture's general disdain of intelligence, especially when it's combined with expertise acquired via hard work. We're living in the most technologically sophisticated society in history, and most of the people hold expertise itself in contempt. This will end well. I don't think this is an issue of education; the progressive era believed in education as the cure for human ills and it didn't work then. It's more of an issue of hubris, and it seems like every generation, every life in fact, needs to trip over its own hubris in order to acquire respect for expertise. Only now, they trip while holding blasting caps or Claymores, instead of sticks and rocks. Sigh. Never mind, it's too discouraging.

Two comments on concrete: Part of why Roman concrete looks good to us today is due to survivor's bias, where we only really see the stuff that lasted 2000 years. There is also some interesting things with the different mixtures, to your point about local materials being used in its manufacture. Engineering with Rosie (see, e.g., https://www.youtube.com/watch?v=pIz_cMqg3_A) has some explanations of where the CO2 is coming from in making cement and efforts to handle it (as another commenter mentioned, a sizable portion comes from removing the carbonate from calcium carbonate).

Roman Concrete: The Romans had quite good concrete for their time... And it lasts a very long time. But there is nothing particularly special about it. We could easily recreate it. The issue is, that our requirements are completely different. Roman concrete is not built to withstand 10t trucks driving over it nor does it work well for building high. We could use it elsewhere but its generally just much more expensive than other equivalent solutions. So yeah... people just use the fact that roman concrete survived for centuries as clickbait. Alien Communication: I think I misunderstand the point you made about how we should learn to communicate with animals on earth first? We do communicate with animals, we teach them all sorts of stuff. The issue is that we've not managed to make them understand advanced communication skills like language. IMO its reasonable to assume that any alien species able to send an answer is capable of some form of advanced communication. Anyway thanks for the interesting video

I liked the concrete content. One big issue with the durability is keeping it wet while it's setting or curing. I guess if it dries too fast it's not as strong. Modern workers maybe don't have the patience.

Echoing what has already been said, but a 40 minute concrete video would be fire. I was a geoscience major, so I'll get excited any time sand is mentioned.

I gotta ask: why did the Star Trek: Picard video get demonetized by YouTube? (And, btw, I did notice the Captain’s Robe pjs!)

I would like a 40 minute video on concrete

I want more concrete content, specifically on recreating Roman concrete. Can you reccomend a good source?

Thanks for the wonderful video. I was able to set the resolution to 1080

A little more than 50% of the CO2 from concrete comes from the limestone you need. There's just no good non-carbonate calcium in the world, it's a whole long- term chemistry problem. The fuel issue maybe we could solve one day by using hydrogen or maybe electricity (i met a guy once who showed how you can use microwaves to make Portland cement), but the calcium source problem is much more insidious. I'm just saying this because I've been a cement process engineer for like half my life and it's like 75% of my job to worry about CO2 emissions

"Billionaire Guillotine solution" - actually LOLed.

I tried watching Lower Decks since there was an offhand comment in the picard video that it's really good, but I barely made it through the first couple of episodes. It just seems like all the characters are talking overenergetically all the time and every line has to be a quip. It seems okay in terms of plot and characters (though I also get annoyed at stuff like the guy asking "where did you even get those flagons!?" as though you can't just synthesize almost anything instantly) but I just can't stand the dialogue. I have heard it improved with season 2 so maybe I should try starting there instead?

My dad is a chiropracter and it wasn't until I was in my early 20s that I realized the implications of this. That's not the only reason, but I don't talk to my dad any more.

I really liked the Star Trek: Picard video, but I'm also a ST fan so that makes sense. But generally speaking, I watch your videos because, like with my favorite teachers or friends, I'm interested in what you have to say. Btw, I suspect a video about baby names would do well on Youtube too, it has broad appeal and there's tons of little factoids you can include. Like how popular media can boost or invent certain names (Khaleesi has been pupular since 2014). Different languages, alphabets, how some countries have very strict rules, there are joke names, etc.

Antother video that begins with "So"

This is, without a doubt, the wildest no-context chapter list I have ever read

I don't need a full 40 minutes, but I do need to know why they chose that weird shade of green to coat the rebar used in concrete for roads. Take a ride down the Mass Pike and you will see piles of the stuff. Why that color WHY!!! It is so wier.d

I love how concrete et cetera got the most votes from the community yet Angela feels the need to apologise for talking about concrete et cetera. I mean, "love" isn't the right word, but it'll do. Also as someone with a fairly typical Irish name but an extremely unusual international name I've developed a whole complicated spiel about where it comes from and how to precisely explain the rules of pronunciation, so I def agree that name data is cool and interesting.

Oh, oh, I completely forgot I wanted to say one thing. If instead of making more videos about bad SF show you want to *watch* a video about a bad SF show, I highly recommend: https://www.youtube.com/watch?v=UauWDakHQo0 I think you're gonna enjoy it (the video, not the show), because dark matter is an important plot point in the show.

I think your point about people asking for more Star Trek videos is reflective of why there are so many prequels and sequels and remakes and soft reboots and the like, because despite what they say, people so often want more of the same thing they're already comfortable with. I also think that the (astro)physics foundation of your channel brings people here but the wonderfully eclectic nature of your videos combined with your casual and relatable delivery is what keeps us here. Just keep being yourself! :)

If not 40 minutes from you on concrete, have you run into any videos that do a good job about concrete? I might watch that. Science advances - How much is from corporate vs military/Nasa research. For example, plastics - Sabrina and It's a Wonderful Life that have references to people getting rich in plastics companies, and I wonder if it started with military stuff and companies took over, or if the initial development was industrial? Baby names - As a lover of The Good Place, I want to credit Kristen Bell's character in that show for the rise in Eleanor as a baby name. Though it started in 2016 I'm not sure if the timing works out. Subtopic - alternate spellings. I knew an Elinor and that's obviously not the typical spelling, is that always intentional or just didn't know the traditional speiling? Medical misinformation - Covid masking was so frustrating, I remember searching and finding many articles on it from the Sars-COV-1 timeframe. Nothing seemed clear about how much masking mattered on a population or individual level and I gave up on trying to really understand it. Just decided to follow whatever guidelines didn't seem too onerous on me personally. Med misinformation 2 - I've heard mixed anecdotes about how helpful acupuncture has been for some acquaintances I have with chronic pain. I assume it's mostly placebo but do wonder if any of it has real effects just coincidentally.

Regarding Medical Misinformation - it's not just chiropractors that have a great lobby and government protection to keep the money flowing. Agriculture, food processors, pharmaceuticals, and (to a lesser degree) medical doctors all have a vested interest in maintaining the status quo.

I can relate to the name etiquette thing. As you can see, I have a double first name. (It's common in Scandinavia and French speaking countries for instance.) It's one name, not two. I'm not "Per" or "Erik", it's "Per-Erik". But some people (often American, I'm sorry to say) think they can just change my name. For instance answering an email, where they can read my name in multiple places, with "Dear Eric". Yes, not even spelled correctly.

I would love a 40 minute ramble on just concrete actually

20 seconds in and it's already abundantly clear that Dr. C. *still* doesn't understand why we listen to her. I've just listened to a 4-hour-long critique of a Star Trek show even though I've only ever watched two episodes of Star Trek. I would watch 40 minutes on just concrete, even though I don't give a damn about concrete. It's about sharing a passion; when the speaker talks about something they're passionate about, the listeners don't need any other type of enticement. Frankly, I'd probably watch 4 hours on concrete.

Perfect timing. This is my Sunday night sorted. Thanks Angela.
