Local news is in decline across Canada, and this is bad news for all of us. With less local news, noise, rumors, and misinformation fill the void, and it gets harder to separate truth from fiction. That's why CBC News is putting more journalists in more places across Canada, reporting on the ground from where you live, telling the stories that matter to all of us, because local news is big news. Choose news, not noise.

CBC News. What do Celine Dion and the song Old MacDonald Had a Farm have in common? The answer to that at the end of the show. My name's Tom Scott, and this is Lateral. Welcome back to Lateral, the show recently described by reviewer, as delightfully confusing. Other reviews have said that we are an excellent way to feel smart and then not, and great for falling asleep but in a nice way.

We take all feedback to heart, even the one that simply said, why? Fortunately, our guests today are here to provide three strong answers to the question why. First, from the YouTube channel VT Physics, we have VT Physics. Hello there, everybody. Welcome to the show. It is your first time playing, so I will ask the obvious question. What do you do online? What's your channel about? I tend to talk about physics and general science on my channel.

It covers everything from our day-to-day life to new tech and science. One thing you've done that I haven't even dared. to start is to move into short form. And like, a lot of the stuff you're making now is just quick debunks for short form stuff. How has that been for someone who started doing long form stuff? That's it. Well, making short form video is so much fun because you get to do them so quickly within a day or two. You can't produce a neat video that encompasses all the signs that you want to talk about, but in a fun and bite-sized manner. And I guess that's how it reached a, wide number of audience because there's simple concepts and yet's relatable. And I've had so much fun

making them this year because I got to collaborate with some of my favorite creators out there. And it's just been, yeah, one crazy year for me. It feels like the barrier to entry on long form is so much higher now that it's just really fun to just make short stuff. It is, yeah. And with somebody like me who's not very techy in terms of editing videos, and not having a super high-quality computer, you could literally edit a video within half an hour on your phone. And if anybody out there is interested in starting a short-form channel or even Instagram Reels covering news or science,

I really recommend that as a stepping stone for anything else. Which does give me a very nice segue into our next guest. From the YouTube channel VVTV and also VT Physics' little sister. Veevie, welcome to the show. Thank you. Thanks, Tom. Hi, everyone. I'm VVee from VVVTV. And yeah, I guess following in the footsteps of VT physics, my older sister, decided to also embark on the journey of like short form videos, like VT mentioned. Yeah, it's, I love talking about news. I actually, my background was in journalism. So it was really interesting for me to actually discover this style of news telling or story.

telling. So, yeah. If you get this many YouTubers on a call, it's like a limited amount of time before someone mentions the word algorithm. So I'll try not get too inside baseball here. But what's it been like for you starting out with shorts then? I personally found it easier to almost like go viral. That one hasn't been the same since COVID, has it? I know.

Viral in the content sense. because, yeah, I think I had some videos where you touch on, like, hot topics or things that's being really circulated, you jump on that bandwagon or you add a twist to it. It's actually, yeah, easier to kind of get your content seen. And obviously, with VT's advice and help as well, that journey has been a lot easier for me. Well, very best of luck on the show today, our two new players and relatively new YouTubers are joined by, someone who's been on the show plenty of times before, an old hand at both Lateral and YouTube, like myself.

A veteran. Right, sorry, a veteran. Now, that does feel more like you've been in a war than on a social media platform. But I don't know, we've all got our scars. Jeff Marshall, welcome back to Latour. Hello, Tom, thank you. Hello, Bibi, hello, B.T. You have been making videos about trains for,

I think, about as long as I've been making videos about curious things. Are any puns to branch out into short form? If anything, I've gone the other way. Worryingly, I am so old now, I've been doing this 10, 12, maybe 15 years, and I've dabbled with shorts, but if anything, I've decided that my future... I guess I'm fortunate enough to have established an audience, and if I don't put out a short every day, that's fine.

Sometimes they'll wait a week or two, and I'll put out like a much longer form video. So just this morning, I've been editing like a 25-minute bit of epic. It's terrifying, isn't it? Yeah, but it works. And I'm very fortunate to be in that position, and I do it. I do not do that. Well, welcome all three of you. Good luck to this show that as I record this, is not going out in full episodes on YouTube, and it's instead on Spotify. So good luck on this brand new medium.

As Lord Tennyson once wrote, There's Not to Reason Why. Oh, actually, no, it is actually yours to reason why. So let's charge into question one. Thank you to Eli Gerouskas for this question. When discussing their favourite games, Himari, might tell Ryan to perform a 214, 623 or 41236. Why? When discussing their favourite games,

Himari might tell Ryan to perform a 214, 623 or 41236. Why? Straight away, that sounds like soccer formations, like you get the classic 4-4-2, but it's not that, but that's what it made me think of. Interesting. I immediately go to like steps, like a dance machine, where you would like step on like a one, two, three, four, five, six,

and you'd go like two, one, four, and those are like the steps. This is where I show off some of my weird knowledge of like arcade dance games. There is now a machine out there which has all nine panels for that. Because Dance Dance Revolution was up, down, left, right. Pump it up with the diagonals in the centre. There is now one that has all nine. And VV, you are not too far away with that, certainly along the right lines. It's a dancing thing.

Is it a dancing thing? That's a physical thing, rather than something like a board game. Jeff, you picked up on the... Unfortunately, the wrong part of that play. Oh, okay, no, so it's not a dance part. Okay, not the dance part. Or is it more of a navigation thing? So if it's not dancing, could it be some sort of angles,

bearings, or steps that need to take in order to get to the next stage or next location? Now, next stage is probably a good one in there as well. Veevi's actually much closer than he might think. Okay, so it kind of... It sounds like it's like steps or like some kind of like panel, panel movement. Yeah. Okay, too...

Sorry, Tom, can you mind? You said game or games. You didn't specifically say board game or computer game or... I did not, no. Okay, so it has to be something physical rather than something that's digital. I think it's probably both in this case. I know it's an unhelpful clue.

but really like Vivi is it's not a dance game it's not one of those in arcades but honestly not far away oh oh I know I know I know could it be like okay I'm thinking six right

because I think you mentioned the upper number is six wait does a guitar have six does a guitar have six strings I just need to oh is it like guitar hero

Ah, again, not the right genre. Like, you have got there very early. This is a video game. Spot on video games. As I say, six is the upper number. Six is the highest number on a standard dice. Nine is actually the upper number here. Oh, nine, you said there was a nine.

Okay. It's a nine-sided dice. Himari and Ryan, the names aren't specific, but there is a bit of a different background between them. Himari and Ryan. I've watched the show before, Tom, and I feel like there's been so many, there's been so many questions where it's like, Himari's actually a panda, or like...

Oh, yeah, no, you've clocked on, you've clocked on very early here. No, there is, let's say a language barrier here, between the two humans, theoretical humans, but humans mentioned in this question. And are they competing against each other, or are they on the same team? Or would that matter? It wouldn't matter for this. I think it's safe to say they're giving each other advice or tips or... just discussing the game.

And I just check, they are humans. There's no computer interface. It's like an AI, an AI robot involved in playing one of the players. Okay, no, just making sure. Okay. Actual humans. Okay. And they're giving each other clues?

Or is it like a clue that Ryan has to guess? Or actually, is Himari just giving Ryan instructions to navigate somewhere? Veevi, you were so close with just your very very, first guess. Like, you are seeing that panel for the dance game and you are looking at the markings on that and you're giving numbers to that. You are so close, it's just not a dance game. Is it more like a battleship kind of game? But you did say it's not a board game, right? It's not, no. You're so close. You've got so close so early. And then I've managed to just kind of skim around the answer. If you look at the keyboard in front of you, you might,

be able to work this one out. Oh, is it to do with the directional arrows on the, on the, because one is bottom left, three is bottom right and all that. Is it that? What are you looking up there, Jeff? Not the numbers across the top of the Quitterkeeper, but on the right-hand side, the number pad, is it that? Hang on. Yes. Okay. Yes, it is. This is why I said you were so close. I'm going to, you're just, you were kind of right, just the wrong appendage. Can you give us one of the numbers again in the question? So, four, one, two, two, three, six. That makes like a U-shape. Yes, it does.

214. A pointing left bottom arrow. Yep. 623. Is a pointing right bottom arrow. Wait. So it's directions. It's directions, yes.

Absolutely right. It's which order you're pushing the keys in. Absolutely right. And if you have a language barrier, that's a great way of passing things back and forth, patterns you might need to push. Now the question is, have any of you played or know the genre of game where that might be useful?

No. I'm so old. Oh, no, Jeff, this was in arcades when you were... Oh, okay. Oh. Wouldn't have been a numpad back then? Would have been a joystick, but... Like Street Fighter? Yes!

No! Spot on! This is notation for beat-em-up video games. Wow. So anyone can understand it. regardless of the language. You might not be playing on a numpad. You might be playing on a joystick or anything like that,

but the numbers they use are the directions to push the joystick. Because you're right, Jeff, it's a lot easier internationally to say 4-1, 2, 3, 6, than it is to go, it's kind of a you-shaped half circle. Well, you don't have you in your language. Well, it's kind of like, right. So this is a notation for joystick movements in fighting games. That's great.

Each of our guests has brought a question along with them. We will start after that solve with Vivi whenever you're ready. This question has been sent in by Julian. In 1999, passengers on American Airlines suddenly experienced a noticeable improvement in comfort. Something that schools of mackerel already did. What changed? I'll repeat that. In 1999, passengers on American Airlines suddenly experienced

a noticeable improvement in comfort. Something that schools of mackerel already did. What changed? And you definitely said mackerel. The fish. The fish. So not just fish in general, but specifically mackerel. Yes. Oh, God, do I take the risk of sitting out on this one?

Because I don't know it, but my brain's just put something together. All right, if this is... Is it anything to do with business class? Vivi. No. Okay. Okay. So here's what I was thinking.

1999 is about the time that airlines started doing life flat beds in business class. I actually think it was maybe 2001 a little bit later than that. And the way they did it, I think it was British Airways that did it first, was they realized that you can fit more people in if you kind of do a herringbone pattern down. So people's, so one passenger's feet are next to the next passenger's head. Like there's a divider between them. They don't know that, but you can shift more people lying down

if you design the seats that way. I was like, oh, that's how macro... No, it's not. That was just wrong on the diversion we didn't need. Okay, fine. Is it anything to do with boarding, speed of boarding? Because that's always a great,

a great contentious topic, isn't it? How fast to get people on and off the plane? No, not to do with boarding. So it's once they're sat on the plane in place. Correct. I would say it's, yes, it's post-boarding, on flight, in flight. It must just then be like spacing or legroom or don't hold your seat back

or something that mackerel's do when swimming to give each other space while staying in a shoal. Is that the collective noun for fish? I think so they're swimming together but with maximum space in between or something. Well, Jeff, you're thinking about spatial comfort here, but I was more thinking about mackerel. Are they quite streamlined? is that to do with perhaps the way that's, I don't know, like air conditioning is controlled in an aircraft?

I was just thinking that when a predator plane suddenly arrives, they all scatter. Very good. Well, passengers can't really do that on a plane. They can if they try hard enough. The two thoughts from Jeff and VT around like the way mackerel swim, or you guys can continue thinking about the types of in-flight activities. So what's part of the experience in flight? You watch a terrible movie on a tiny four-inch screen.

What am I? You open some tiny packet of snacks that are flavorless. You complain about the lack of legroom and hope the person drunk of you doesn't put their seat back. What? Jeff, you mentioned the tiny screens. I would continue there. Continue there.

Okay. Not necessarily the screens. Watch Netflix, what? I'm just thinking about the intensity of light in an aircraft. Could Macquaras adjust their eyes somehow to reduce the brightness of external stimuli? Not light. Sound. Sound.

Sound. What? Yeah. Sound. I don't know what noise Mac will make. I don't know if I will make noise, Jeff. Do fish make noise? Do fish make noise? I don't know.

Do fish make noises? I have no idea. You're like the other side. It's, okay, so how do you make the noise environment on a plane better for the passengers? Well, the noise is the, uh-uh, of the airplane, isn't it? It's kind of this low, rumbling, deafening noise. Yeah, that's just constant. So how do they make that better? Did Macro have some built-in earplugs or something that humans don't have, and we've adopted?

Oh, no, what? You actually... I thought that was stupid, and you actually went, yes! No, that's not too far. Continue, continue on that kind of line of, like, noise cancellation? Anything to do with that? Now I'm just thinking of hitchhikers where they put the yellow fish in the ear. They're like, translate. That's where I've gone, but instead it's...

There's no way American Airlines gave out three noises. canceling headphones? No, you got it. Or could they just play a noise, like play some sort of background noise to cancel out? Do they figure out a way to like noise cancel inside the plane? So I think VT, Tom, you guys got it with the noise cancellation.

You guys are just missing... How? Yeah, in relation to mackerel. So it's something that schools of mackerel already did. Does it have to be a problem? bunch of macaroes, or can it be a single macro on its own? It schools of fish, so it's a bunch of, bunch of macros. They generate some kind of frequency that cancels out the noise of the ocean or something. What? They vibrate their fins at a certain resonance or something. It's going to

be something really, really, really bizarre. So, Jeff, you said they would, they, did the fish make noise? Technically, they're going to make a vibration in the water, right? And if you've got like 10,000 fish all swimming in sync, what you're going to get is this massive, like, resonant noise that attracts predators? Like, I said my thing about predator planes arriving, right? Like, not that, but predators arrive for the mackerel, because they're all swimming in sync, so they desync, which makes white noise instead of a resonance, right? Yes, yes, yes, yes, yes, yes.

I don't know how that translates to a plane, but I've got the fish bit. Yes, no, and I think, Tom, you said, like, oh, surely they weren't giving away... I said they weren't given away free noise-canceling headphones. Yes, Tom, they were. So in 1999, Boast actually introduced its first consumer active noise-canceling headphones. And they actually debuted it on American Airlines. And a lot of this technology was actually in schools of fish as well, including mackerel, where they generate less noise than just individual swimmers of the.

fish. Because of the random timing of each fish's movement, they'll actually partially cancel each other out. Therefore makes it harder for predators to detect. There's no way American Airlines was given those out for a long. And then, and then for the dinner service, they serve mackerel. Thank you to J.P. Etiuba for this question. In 2012, Margaret brought a tortoise she'd found in her garden to a wildlife rescue centre, concerned that it wasn't eating. Which 11 markings did the Wildlife Centre find on the tortoise that explained why? I'll say that again. In 2012, Margaret brought a tortoise she'd found in her garden to a wildlife rescue centre, concerned that it wasn't eating. Which 11 markings did the Wildlife Centre find on the tortoise that explained

why? This is going to be something like tortoise had tried to sort of duck under something and had left marks on its shell on the outside. It tried to go somewhere where it shouldn't have gone to not get food, but for some reason to avoid food. I'm assuming it's marks on the shell of the tortoise. And you said it wasn't eating. It wasn't eating. It wasn't eating.

And she was worried about that. And when they found those 11 markings, they knew exactly why it wasn't eating? Exactly why. Or was the tortoise sort of being antagonized by like a fox? or a cat or something, that was eating the tortoise food and leaving a mark on the tortoise. I'm just wondering whether it has to be 11 specific marks, as in did those mark, 11 marks come together to make a certain pattern, certain word, or were they separate markings?

You are actually getting closer with that. They are specific markings. Did he spell out a letter, or a word perhaps? Yeah. Had somebody been writing on the shell of the tortoise with a piece of chalk or something? Yeah, the markings were letters. You're right. Oh my gosh, I'm getting like an imagery now. And it's kind of creepy. Oh, hold on. What are you saying?

I'm seeing like, you know in The Shining where they had like red rum on the wall? And it's like spelled like murder. A haunted tortoise. Oh, that's really pleasant to say. Haunted tortoise. So Vivi are you thinking that it's the owner who's put those markings on the tortoise? Rather than...

Or is it an angry neighbour? The tortoise is stealing the lettuce from the angry neighbour's garden and they're writing on the tortoise. No, hang on. Is it... Why would you write on a tortoise? That,

Jeff, if you can answer that question, you've got the whole thing. Okay. I'm going to find out at about five minutes, aren't I? Okay. Why would you write on a tortoise? The 11 markings, did it spell anything? Oh, yes. Absolutely. So they were, okay. And the owner definitely knew that this is a live animal. Keep going, Viti.

I'm just thinking that it has to... It reminds me of perhaps the owner, maybe a blind owner, has to feel for any markings to realize that's what he has. Or is it Margaret, do you say? What she has? Margaret, yes, Margaret. In front of her, if she doesn't know, then she might have to feel those marking to work out what everything is in her house. You've spotted there's something strange about this tortoise, PT. I'll give you that much.

I think it's more like something strange about the owner. Yeah. Yeah, I think VT's under something there. So, owner is perhaps not the right word here. Margaret brought a tortoise she had found in her garden. Oh, it wasn't established that it was her tortoise. It could just be a rogue tortoise. It could just be a rogue tortoise.

Well, like a neighbour's tortoise that had escaped maybe in search of food and had come into Margaret's garden in search of food. So you just spell out something like, do not feed. That's not 11 markings, is it? Or do not feed. Help, my owner isn't feeding me. A tortoise had written on its own show. Vita, you said something earlier that you kind of moved away from,

which was just making sure that this was a live tortoise. Right. Is it just not alive? So, yeah, so I'm thinking, did Margaret Foneman, find a shell in her garden, thought that it might have been like a live tortoise and then brought it to the, yeah, brought it to the wildlife reserve. Getting very close here. Not just a shell, though. Oh, like, was it like, um, it was actually like a squirrel that was inside a shelf?

Oh, oh, no. No. Wrong spectrum. Okay. I love the image of that happening where you get to the wildlife rescue center, to put the shell down, and then just a bushy tail comes out one side, and they're very confused for a little while. No, no, this, I have missed one word out of the question here. Margaret definitely brought a tortoise. There's an adjective we've kind of skipped over there. A dead tortoise?

Not live, not dead. Hibernating. Not live, not dead. A stuffed toy? Oh, it's not a real tortoise. It's not a real tortoise. No. So what might those 11 markings, those 11 letters have been?

Bearing mind, this thing is good enough to fool someone into thinking that it's a real tortoise. Like, made in China? Spot on! That is 11 letters, made in China. We're on the underside of the tortoise. This is Margaret Parker, who spotted what she thought was a baby tortoise in her garden. She brought it inside, it wouldn't eat, She brought it to the Knoxwood Wildlife Rescue Centre,

explained that it had no appetite, and the volunteer put on the glasses, turned over the tortoise and saw Made in China. George Scott, the founder of the Rescue Centre, said she did the right thing. A lot of these ceramic models can be very convincing. Jeff, we will go over to you for the next question, please. All right. Hello, this question has been sent in by Jesselin.

Okay, the question is, buses, streetcars, and light rail vehicles in San Francisco often have the word particular, particular on their destination sign. Why is that? Buses, streetcars and light rail vehicles in San Francisco often have the word particular on their destination sign. Why is that? Buses, streetcars and light rail vehicles.

I love that I've been giving a transport theme question, by the way, because of David. Thank you very much. And they had it on their... Sorry, did you say their destination? The destination board. So that's going to be the thing at the front that tells the passengers where it's going.

The word particular is there. Those are very different things. Like, in San Francisco, your buses run, you know, all around the city and the area. Streetcars on a few lines. But light rail is a whole separate system with separate lines. Light rail, I would just say, is trams.

To me, that means trams. Maybe the Americans are called trams light rail. I don't know. Who's been to San Francisco? Who's ridden a street car? That's me. There's, yeah. They have the BART. They have Bay Area Rapid Transit, which is, if you imagine the Doctlands-like railway, Jeff, just much worse. Oh, no, I've been. Sorry, when I ask my own question, I have also been there. Okay, yes.

What's wrong with the DLR? Come on. Nothing, I'm just saying Bart's worse. Oh, I see. You said the word particular is on the vehicle or on the destination sign? It's on the destination sign, yeah. The word particular is there. And I'm guessing it's followed by other words, or there are other words that comes before that.

Nowhere in particular, they're just incredibly whimsy street... They're incredibly whimsical streetcars that don't follow an actual route. The light rail just goes to any destination the driver feels like. Tom, you don't. No. When you've said it, but you haven't given the right reason. Why could...

Okay, no, there's no... Why would a light rail have nowhere in particular on the front? That's the opposite of a railway. That's literally the... A railway is a rail. It goes to a place. It can't go nowhere in particular. I mean, like, I get it, though, because I've been to Lisbon or, like, Prague,

where you do take these, like, vehicles for tourist pictures, and you do it for, like, an attraction, a tourist attraction. could this be, I can see the attraction in it. I can see people going to San Francisco and like, take a streetcar, get an Instagram photo. So I can confirm that Tom is exactly right. It says nowhere in particular, but you haven't got the reason why.

So I feel I'm not giving all the points yet. You need to get why. I can confirm there is no place called particular in the San Francisco area. And it's not to do with the attraction of it, Like, not to do with... Not in a tourist sense, no. Oh.

I mean, I've been to cafes and restaurants where they put vehicles together as boots and you sit there to dine in. So it's not for tourists, but it's for visitors. I'll give you my own clue that's not on my question sheet. If you saw that coming down the road towards you as a tram going to nowhere in particular, what would you think? I'd be tempted to get on board.

that. Oh, honest. Well, then, that it's not working. So is it truly that it does not have a destination, or is it just hidden from... No, no, go on. Potential passengers. No, go on. The first bit, what you just said, yeah, it has...

So there's no destinations. Well, it does have a destination, but it's, it's... Oh, you're so... It's just out of service. There we go. Oh! They choose nowhere in particular. Out of service for whimsy?

Yeah. Since 1959, public transport in San Francisco has used the preset destination of nowhere in particular when they are out of service or repositioning their vehicles. It's to discourage you from getting on, which is hilarious, Tom, because you're like, well, I'm so getting on that. Out of service, I understand nowhere in particular. As a tourist, like, sure, that's just wimsy. You'd be like, yeah, where does that go?

Yeah, I do the same, except I knew this. I'd heard of this before. So when I got this as my question, I was like, I know this. I thought it was one of those mystery destinations that you pay probably too much to go on. Oh, yeah. Magical mystery tour.

But now what will happen is that some, some enterprising person somewhere, they renamed a town like in New Mexico. Somebody will now rename a place or their town or village, the particular, so that you'll say, so you can now say you're going to particular.

And then open a bar called nowhere. Nowhere. Yeah. Our next question comes from Cliff. Thank you very much, Cliff. In 1963, C.C. Williams spent hours jumping up and down on the spot the night before his exam. Why? In 1963, C.C. Williams spent hours jumping up and down on the spot the night before his exam. Why? Because the exam was in some kind of trampolining gymnastic skill.

Sorry, when you said trampoline, Jeff. Oh, no. My brain, I heard tram. And then I was just surprised by Palline, because we've just been spending so long talking about trams. Carry on, sorry. I think that's some kind of athlete, and the jumping is part of like a warm up. My mind kind of goes to, like, you know when people say, like, when you listen to throughout the night, if you listen to your notes, you will have that, like, memorized? Is this some kind of ritual where it's like, if you listen to your notes and you jump up and down, you can memorize it better?

I was just going to say that before exams, there are people who would punch, what do you call it, air punch or punch the air. Shuttle boxing. Yeah. To get your adrenaline going. And it's not a physical exam or is not some sort of sports that they are involved in, but it's just a written exam. And people actually do that to get themselves ready for the. exam. So I think it heavily relies on what the exam is, whether it involves any physical activities. Those are all very sensible answers, but not necessarily lateral ones here. I think I'm going to,

I'm going to say, drill in on some of the other reasons that might be in here and some of the other exams that might be involved. Wait, hang on. It's not like a dope testing or something, and he's trying to sort of get something out of his system, is it, or something? No. Okay, no. Like sweating out. Yeah, he's sweating out some kind of substance. Ah, yeah, or like, is C.C. Williams a human? I'm going to ask the question again, is C.C. Williams, a panda? Or a tortoise.

C.C. Williams is a human? Okay. And is that a physical exam that he has to pass? Yeah, it's not a written exam here. Okay, so it's a physical exam that he has to pass. And, I mean, boxers have to lose weights. is C.C. Williams, some sort of athletes like a boxer? What, they're trying to, like, burn up a pound of energy and sweat

by just doing some vigorous exercise to get them under a threshold. I mean, some of them wrap themselves in cling film so that they can sweat a bit more before... No, I've never... Is that a thing? I've never... Yeah, yeah. Don't they do that? I'm totally going to Google that day. Okay, all right. I've learned some. That's amazing. Okay, all right.

Is there something in the year as well, like in the 60s? Was it... Oh, good spot that this is 1963. That is relevant. Couldn't have happened before, I think, the late 50s here. What was invented in the 50s, everyone? Think, when did television come in? 40s, 50s?

Was it some kind of exercise thing on TV? Was it the first ever exercise show on television? VT, when you talked about losing weight to try and meet an arbitrary threshold, something along those lines, yes, he's trying to meet a single, very specific requirement. It's not weight. Height?

Oh. Yes. I mean, yeah, I've definitely heard of myths where you jump up and down to get taller. What, because it uncompresses your spine or something? What? No. What? Yeah, I've definitely heard of those before. You are correct with height, Vivi, but it's actually the other way round.

He is trying to compress his spine. By jumping up and down. By jumping up and down. So temporarily, for the exam the next day, he would be shorter. No, because I'm thinking, like, if you apply to me in the army of the police, there's a height, there's a minimum height, not like you want to be taller, not shorter. If you want to go, if you want to go on a roller coaster ride, you have to be a minimum height, taller, not shorter.

Oh, now you're close, Jeff. Oh, oh, rollercoasters. And my note say he managed to temporarily compress his spine enough to measure under six feet and technically, satisfy the requirement. Right. Now, how much of that is actually due to the jumping? Don't know, but apparently it did work, just temporarily. So there's a theme park which has a maximum... Oh, it's not right. It might feel like a roller coaster, Jeff, but it isn't.

Like a jockies? Oh, they do have to be short, but not jockeys here, no. No, but you got very excited when I said roller coasters as if... I did, as if... Because this has been described like that. Oh. as being the greatest roller coaster that could ever be. Like F1 drivers? Close.

Wrong axis. Do you have to be sure if you want to go into a submarine? VT with submarine, you couldn't be more wrong. Hot air balloon, for some reason. My brain has gone to. Literally getting closer, Jeff. Oh, um... Oh, astronaut.

Astronaut. Yes. For NASA's third astronaut selection, in 1963, candidates had to be no taller than six feet because the spacecraft were cramped. C.C. Williams was a highly qualified test pilot, but he was ever so slightly taller than six feet. So the night before his exam, he spent hours

jumping up and down on the spot, trying to compress his spine and just get in under the limit. And then when he was in space, did he extend back to his normal height? So this is a question we've had on lateral before, and yes, that happens. Astronauts get taller, and they have to have their spacesuits measured

a couple centimeters too big, because after a few days in space, they will get taller. And too bad, he couldn't jump to a shorter height. I feel like I should ask the physicist in the room. Your spine does compress over many, many decades, so that you're much shorter in your 70s than you were in your 20s by about a centimeter. I also heard that if you sleep on your back, and if you sleep on a hard bed, you actually get taller because you straighten out your spine. I need to do that.

VT, we will go over to you for the next question, please. Right. This question was sent in by Jeff Leiner. Why might pediatric students be asked for the normal range of porcelain in a child's blood thanks to Harriet Lane Handbook? I'd read that again. Why might pediatric students be asked for the normal range of porcelain in a child's blood thanks to the Harriet Lane Handbook?

Wow. Awesome. There were so many words in that question. So I got pediatrics, porcelain, child's blood, and Harriet Lane's handbook. The notes that you take during this show are ridiculous. They look like a crime description. People normally have levels of porcelain in their blood? Is that a thing? Not that I know of. No, right. That's a very valid question. So, porcelain's got to be a standard for something. I know very little about paediatrics.

And it's specifically pediatrics. So you would look for porcelain in a child's blood, but not necessarily an adult's blood. This could be applicable to adults too, I would say. Although the scenario here is that we are using the scenario with pediatric students, but the same handbook could be given to other fields in medicine. Porcelain, why porcelain? Porcelain is normally used for pottery and crockery, right? Yeah, you make pots, you make, yeah, it's clay.

I'm just doing free association in my head. It's the name of a Moby Alba. Yeah, I was thinking Moby. I thought that, I don't want to say that. Tom said it, that's fine. It's fine, I'll be the one that looks ridiculous in this episode. I was humming Moby in my head, yeah. Not any of his songs, just the word Moby over and over again.

Jeff, I think you mentioned something about porcelain in blood. Like, do we normally have porcelain in blood? I wouldn't have thought so. No, there's no way. It's fired clay. That's a manufactured thing. If that's in blood, something's gone really wrong. So what is it a metaphor for? It's not like there was a porcelain factory.

somewhere and then there was a disaster and then lots of porcelain particles were in the air, you know, for like months on end and all the local population got breathed in porcelain fumes. Is it like, for example, like a percentage of calcium is porcelain or something? Like I'm thinking along the lines of, hey, who knows whether you can make clay out of calcium? But I think you were right in doubting that anybody would have. have porcelain in their blood. Okay, so in that case, it's the question you ask to make sure the other person's paying attention and you want an answer of zero.

Or you want an answer of no, what? Can't, don't understand you, just to double-check the numbers? That is very close. Oh, okay. But why porcelain specifically? I mean, there is porcelain doll as a phrase. Like, they used to be, I don't know them they're popular anymore, but they used to be like quite rigid porcelain dolls of children that people would collect.

So that's an association with paediatrics. I think you got the first parts already, seeing that is to test whether somebody's paying attention or not. But why would they include it in a pediatric student handbook? Is it a euphemism for something else? Like... Not quite. Did you put a date on this?

Is this like back from the 1960s? This is a very old handbook, but it's not a modern handbook? This is a pretty old handbook, but they do update it afterwards. Apparently, they have different edits of this, and the concentration of porcidin and blood would change later on with each edit.

Okay. What if, rather than wanting a zero reply, like, what if it's like, in the handbook, if that's filled out, you know the student is lying about having done their homework because they've just put random numbers in each one. It doesn't quite hold together. It's almost the opposite of that is like, it's almost like the student is too studious or they've read the handbook one too many times. So it's just to count how many people have read

a certain book, how many a percentage of people are paying attention? They're just, they want to know how many times. Those who have read the handbook would know this number and I'm thinking of all my medical knowledge and knowledge about hospitals come from scrubs. So think about how in scrubs, they always have like medical rounds. I think they're called rounds, right? Yeah. Where they're asked questions from somebody who's more senior than they are. Oh, so could it be like if someone has just ticked it off without checking that?

question, they would know that they kind of just did like a lazy job? Yeah, so like somebody who with a photographic memory might be able to read that patient handbook and just give you the number of the concentration of porcelain in someone's blood. But then the moral of the story is that they don't want pediatric students or medical students in general to just memorize hard facts. They want them to think outside the bogs really question what they're reading or the facts that they've been given and think um think laterally rather than just focusing on facts. It's a trap basically.

It's so someone, so the medical student learns to go, porcelain, because if the seniors made an error, they need to be able to call them on that, that sort of thing. Wow. Yeah, yeah. So it's basically a prank that's passed on. So this is the Heron Lane handbook, which is a medical guide. And for decades, its editors have quietly included a fictional laboratory entry for the normal range of porcelain in blood. And currently, I think it stands at 9 to 24.11 milligrams per decimeter.

And that number, although it sounds really exact, are just based on editors' birthdays or anniversaries. And that's why I was seeing that when they update the NIC's edits of the handbook, that number is going to change periodically. And this prank, they expose students who relied just on photographic memories without questioning any possibility. And it also reinforces a core lesson of medicine. So you shouldn't be accepting everything you read uncritically. And even from a trusted source like the Harriet Lane handbook. Which just leaves us with the question from the very start of the show.

this in, what do Celine Dion and the song Old MacDonald had a farm have in common? Does anyone want to take a quick guess at that before I give the audience the answer? Both in the same key or tempo of one of Saline's hits? I don't know. It's not a chord sequence, but... E-I-E-I-O? It's good... Keep going, Vee-Vee-Vee. Like Selim Dion? Like C-E-L-I? Yes. The vowels in Selene-D-on are E-I-E-I-O in order. Well done, V-Vie-Vie. Thank you to all of our players, where can people find you? What's going on your lives? We will start with Jeff.
