Laura: Hello and welcome to another episode of, uh, Lex Education, the comedy science podcast, where comedian me, Laura Lex tries to learn science from her, ah, nerdy, younger, non comedian brother Ron.
Ron: Hello. I'm, um, brother Ron.
Laura: For more Lex education content to keep up with us in the discord private chat. For extra bonus episodes, find us on patreon.com lexeducation. A lot of the podcasts I've been listening to lately just sort of like, just run that at the top in their spiel. And I'm like, that's clever. Yeah, they don't do it as a grovelling apology. They just do it as a, like, of course you would. That's how this works. You know, Mackie, you must. They also don't have dogs crabbing about the lining. So I'm not saying it's something we have to do every time, but I thought I'd roll it in today and see how it went.
Ron: Yeah, okay, nice.
Laura: Why have you pulled that face? Have you got some begging coming up late?
Ron: A lot of grovelling in the notes.
Laura: Hey, I'm not saying we can't do both every episode, but I thought that flowed quite nicely.
Ron: Yeah, yeah, no, that was good. Yeah, I think, um. Do you want some notes? Yeah, um, I think maybe do it in your own voice next time for a bit more of a. No, you didn't. You turned on kind of a sort of silky, like, you know, like you're doing a thing.
Laura: Yeah, but imagine you've never listened to this podcast before, and you just download this episode to give it a go. There might be somebody listening to this. Who? For them, that's, you know.
Ron: Yeah.
Laura: And they want silky smooth podcasting. And then ever so slightly, my voice returns to it. Screeching, irate, horrible tone. But they're already suckered in by then.
Ron: Um, no, I think more what you want.
Laura: Oh, hello. Join a patreon for stuff.
Ron: But that's not your voice either.
Laura: What is my voice then?
Ron: This one.
Laura: Hello, join the Patreon. Join us on patreon.com.
Ron: We'Re not even supposed to be plugging Patreon. We're supposed to be playing the cheerful Eiffel festival.
Laura: Oh, well, they can't come and see that. If this is the first episode they've.
Ron: Ever listened to, why are we only appealing to them?
Laura: Because the other guys are in now. They're in the cult. They're stuck.
Ron: They're clearly fucking not.
Laura: Um, yes, right up, uh, top. Hey, guys, this Sunday at the Bedford in Balam, which I'm pretty sure I put out a promo video the other week calling it the Balham in Bedford. So don't go to Bedford. Go to the Bedford in Balham. It's on Bedford Hill. And come and see our cheerful, earful live show we are doing.
Ron: You're not gonna read the notes then? I. Right.
Laura: Uh, no. Okay, I will.
Ron: I pray.
Laura: For the love of a good fuck, please buy tickets. Please. They bumped us up to the big room and we're letting Giles down. We're not letting Giles down.
Ron: We're really letting Giles.
Laura: No, because I said small room, and he said big room, and I said small room, dude.
Ron: Yeah, because he believed in us and we've let him down.
Laura: So we're doing a spooky Halloween episode, fancy dress. Welcome but not essential. We, for example, will not be in fancy dress. Uh, I will be exhausted because I will be driving home from Edinburgh if I can afford a fourth hotel for one tour night. Um, and we're going to be talking about the science of werewolves.
Ron: Yeah.
Laura: Just like Mackie Mackie. You're a werewolf.
Ron: Turn the gain out. See if we can.
Laura: She's so near the microphone.
Software that generates the transcript every week annoys me. I'd find it more annoying if it stopped
We're back in Ron's kitchen. By the way, um, did everybody like our AI generated rendition of Ron's kitchen?
Ron: It's bang on.
Laura: Yeah, because basically the, um, what's it called? Software that makes the transcript every week that we put out for no apparent reason.
Ron: Um, you can stop, man.
Laura: I can't stop now because I'm doing it. So it would really annoy me if it stopped now. I'd find it more annoying if it stopped than the pointless work I do. But maybe one day there'll be a deaf person that wants to get involved and wants the transcript. And for them, super worth it. Anyway, um, yeah, the software that generates that also every week offers, do you want your AI episode art? And I'm always like, no. And then sometimes I look at it out of curiosity, but it clearly only uses the first five minutes as prompt. Um, so it's every week it's like a dog and a cat and just some nonsense. But I quite enjoyed your kit.
Ron: Let's start posting those more.
Laura: I post them sometimes.
Ron: Oh, nice.
Laura: You could do it too, if you like.
Ron: I wouldn't know how.
Laura: It's in our headliner, which is what we use for transcript.
Ron: Interesting. Yeah.
Laura: Mhm.
Ron: Do it in your own voice, Mackie. You're good enough, man
Ron: Anyway, enjoy this first physics exam.
Laura: Yeah. How is it, Ron? You've edited it?
Ron: It's a good episode, actually. If you look at the notes, there's loads of episode titles, even from the first 25 minutes.
Laura: Is that all you've edited so far? Huh?
Ron: The first 25 minutes? Yeah. What's
00:05:00
Ron: this? What's this beef about?
Laura: No, no, no.
Ron: Why m being like this?
Laura: Cause you were mean about my voice. Oh, yeah.
Ron: No, my note was, do it in your own voice. As in, like, your voice is nice. You don't have to do this other voice.
Laura: It's my own voice.
Ron: That wasn't your own voice, Mackie.
Laura: Was that my voice?
Ron: I said, do you want a note? And you said, yes.
Laura: I thought it would be a nice note.
Ron: It was. It was. You're good enough, man. You don't have to put on this other voice.
Laura: Shut up, Ron.
Ron: Anyway, enjoy the episode. Test, test, test. Iran. Um, um, um, um, uh.
Laura: Oh, God, it's 44 pages. That's eight pages longer than last night.
Ron: It's okay. We have snacks tonight. Not enough. Uh, we're boozing tonight.
Laura: God, I've been boozing for hours.
Ron: Yeah, you did crack that wine when you got home. That's okay.
Laura: I'm dreading this exam. How? Because it starts on page two
Look, we're already on question number two.
Laura: How?
Ron: Because it starts on. Sorry, page number two. I mean, it starts on page two.
Laura: Oh, I'm dreading this. Oh, no. And it's a circuit. I fucking knew it would be a circuit.
Ron: Oh, this is why you tried to pitch that terrible system about if you pass an exam, you get to do another one because you knew that you'd fail this one.
Laura: No, I just said, maybe we won't do higher tier unless I get 75%, at least on the foundation. Because if I, like, get 10% of this, right, what is the point of doing, uh, an entire exam where I only get one question, right?
Ron: What's the fucking point of any of this?
Laura: Well, there's content and then there's bad tent.
Ron: Do you honestly think we're gonna make bad tent?
Laura: Yeah, I guess I do.
Ron: Well, knuckle up. Because we got. We got 44 pages to knuckle up.
Laura: You can't say knuckle up.
Ron: Knuckle. We missed some good knuckle up chat there. Something happened with the mic. That'll be fine. Um, all right, Laura, you ready?
Laura: I mean, sort of.
Question number one. A student investigated how the current in a filament lamp varies
Ron: Question number one. A student investigated how the current in a filament lamp varies with the potential difference across the lamb.
Laura: Oh, shit. Hang on. Am I allowed any formulas or anything?
Ron: Yes.
Laura: The physics equation sheet. Where's that? Where's that? I need that.
Ron: I can send you that.
Laura: I need it.
Ron: You do need it. There you go.
Laura: I really want to get into the fancy biscuits. Oh, is she? Yeah, because I just sent older sister of the podcast is trying to persuade me to move to Bristol.
Ron: Do it. Is that what you point?
Laura: You're leaving?
Ron: Yeah, but then we're closer to the rest of the family and I'll be there for at least another year.
Laura: I want to live near the rest of the family.
Ron: You want to listen to Sarah?
Laura: Yeah, I mean big Sarah.
Ron: Big, big Sarah.
Laura: Big Sarah. Don't tell it. You call her big Sarah.
Ron: Big S. Laura, what is compound p? We never learned any of the circuit symbols.
Laura: Oh, I think I remember that.
Ron: We did cover this.
Laura: No, I don't think we did, but I think I remember this genuinely from school. I think that's a switch. I think that's a switch. I think it's a, uh. So obviously you can't see this. Listen, at home, it's breaking the circuit like a little gate. Oh, Mackie, I haven't given you any dinner. Okay, I need to feed Mackie. In a minute. Um, and it's got two little, like, bangle ends, circles.
Ron: We can't spend this much time on the description of a small drawing of what we both know to be a switch.
Laura: Yeah. Yes, I got it right.
Ron: 1.2. Complete the sentences. The ammeter in the circuit measures.
Laura: Current. Okay, he seems happy.
Ron: The voltmeter in the circuit measures charge. Are you happy with both those answers?
Laura: No.
Ron: Do you want to change either of those answers?
Laura: Does the voltmeter measure potential difference? Is that what the slide is? Is that voltage? It was the slide. Huh uh. Let's change volt. How many helps do I get on physics? 5262? More than two. One more than two.
Ron: What about minus one? And I really fuck you up on one of the answers.
Laura: Uh uh. Oh, God, it feels like the last 24 hours didn't happen. And this is just a continuation of last night.
Ron: We did this for 2 hours last night?
Laura: Fucking. And this is eight pages longer.
Ron: Yeah, that'll be because of diagrams, though.
Laura: It better be. Ron.
Ron: Yeah, I'm scrolling.
Laura: Should I change voltmeter?
Ron: I can't tell you that. I
00:10:00
Ron: don't have the mark scheme open.
Laura: Right now, but you know.
Ron: Yeah, because this is for kids. This is. And Laura, this is for the dumb kids.
Laura: A, uh, voltmeter measures.
Questions get harder towards the end of the day, Laura says
Ron: We can't spend this long on question two.
Laura: Well, why? Question two is the same as any other question, and if you'd help me, it would go quicker.
Ron: No, Laura, they get harder towards the end.
Laura: Do they?
Ron: Did you not notice how all of the big, long questions were towards the end of the day?
Laura: There's only one big long question. No, there were multiple.
Ron: I think you're really thick.
Laura: I think you're really rude, and I'd rather be thick than rude.
Ron: I'm being really rude to you because I know respect you.
Laura: Well, I love you.
Ron: I love you, but I don't respect you.
Laura: Well, I don't need respect. I've got strangers on the Internet.
Ron: You've got wine.
Laura: It's not even wine, actually, Ron. It's vodka.
Ron: No.
Laura: With passion fruit juice and vanilla flavouring.
Ron: Sparkling vodka. Right.
Should I change my answers on question two? Don't tell me
We're moving on to questions.
Laura: No, because should I change my answers? Don't have to tell me.
Ron: I can't even remember what your answers are, whether you need to change your answer. I have. I'm not looking at that right now.
Laura: Should I change my answer? You were extending the length of question two. Should I change my answers?
Ron: You tell me.
Laura: No, don't help me.
Ron: Do you want to use one of your two helps on this right now?
Laura: Can you please just tell me if I should.
Ron: You want to use half of your helps?
Laura: Half of one help. Uh, half of one help. Because it's.
Ron: This would be one of your helps.
Laura: No, uh, Ron, half of one help.
Ron: This would be your head.
Laura: Oh, fuck you, then. Leave it as it is. I don't care. It's a reflection of your shitty teaching.
How will increasing resistance of the variable resistor affect each of the following quantities
Ron: How will increasing the resistance of the variable resistor in figure one affect each of the following quantities. Sir. Current in the circuit.
Laura: Sir? Uh, current in the circuit.
Ron: I just. I just read it wrong.
Laura: Oh, you don't read the tables? I read the tables.
Ron: Yeah, but this is more of a question, so.
Laura: Currently in the search, episode five of exam and you're here reading a table. Here's your fucking mouth. Out my table.
Ron: Current in the circuit decrease, stay the same or increase.
Laura: What was the question? How will increasing the resistance of the variable resistor. Okay, uh, increasing the resistance will decrease the current.
Ron: The mic keeps coming out.
Laura: Hmm. Wonder why. Potential. Hm. Difference across the lamp stays the same.
Ron: Stays the same. Total resistance in the circuit increase. Happy with all your answers there?
Laura: Sure.
Ron: A charge flow of 15 coulombs passes through the filament lamp in a time of 60 seconds.
Laura: Oh, I just got an email about a magical family out of.
Ron: What is it? Where could we go?
Laura: Let's do it. Uh, it's the Brighton lights, and it's in December. Oh, we went to this last year. It was quite nice.
Ron: Oh, this was last year? Then why are they even.
Laura: No, no, they're saying if I want.
Ron: To go calculate m the current in.
Laura: The lamp, do you want to go? It's in December in Brighton. Uh, I sat on that moon, I think, through all of it, maybe.
Ron: Okay, calculate the current in the lamp. Use, um, the equation.
Laura: Fucking just want to die.
Ron: Come on. The quicker you do this, the quicker we can stop.
Laura: Yeah, well, I've lost my pen. There it is. Can you get the fancy biscuits? All right, well, they've come out earlier than I was anticipating, so. 15. Charge flow. 15 coulombs pass through the filament lamp in a time of 60 seconds. Uh, okay, so 15 over 60 equals.
Ron: None of these fancy biscuits.
Laura: I don't know, I just liked the box in the little m and s garage today. Yeah, and I thought you were my. In my biscuits. I'm gonna get some different biscuits.
Ron: They're not labelled.
Laura: 00:25 a ron.
Ron: And what was the sum you did to get it?
Laura: 15 over 60.
Ron: Naught .25 a. Happy with that?
Laura: Mm hmm.
Ron: When the current in the filament lamp is 0.12 a, the potential difference
00:15:00
Ron: across the lamp is 6.0 volt. Calculate the resistance of the lamp. Use the equation.
Laura: Okay. The equation they give me is resistance equals potential difference over current. So the potential difference I know is six. That's over current, which was what I just worked out was 0.25. I, um, believe so. The resistance would, um, be six divided by a quarter, which is 1.5, isn't it? But I am just going to cheque that on a calculator because I don't trust my brain. Hm. Wait a minute. Six divided by 0.25 equals 24. So I'm glad I checked my brain. I think it's 24 ohms. Um. Oh, me. 00000.
Student plotted graph for each component after replacing lamp with resistor
Ron: All right, laura, question 1.6. The stew.
Laura: Why is saying that so excitedly?
Ron: Because I thought it was going to be question number two. Led to scrolls so far, but it wasn't.
Laura: There's caramel in that.
Ron: There's, uh, dust in this one.
Laura: Were cheaper because they're very near their best before.
Ron: Oh, um, yeah, kind of compacts and then becomes chewy. It's not chewy on the first bite. Um, they replaced the lamb.
Laura: I was very tempted then to say, name of your last sex tape, but it didn't really work. So we're siblings, literally, like, name of your last sex tape. Because this sells so badly, you get a different career.
Ron: Student repeated the investigation after replacing the lamp with a resistor at a constant temperature and then a diode. The student plotted a graph for each component, drew one line from each component to the graph.
Laura: Hmm. Um. Okay. The options I've got here are diode, filament, lamp and resistor. And then I've got four graphs. Shit in Christ current. I, um, mean, do you think that.
Ron: Sound of just Mackie's mouth is going to be on the podcast?
Laura: She's really nibbling her feet a lot at the moment.
Ron: Yeah. Um.
Laura: Um. God, I don't even know how to go about answering this. What investigation? Was there an investigation happening? Fuck. Oh, the panic mist just makes everything so I've got like a, like a musical f forte shape, just a straight line, a real wiggly worm. Um, and then like a whoop, the tail's alive kind of a guy. Those are the different crafts I got. I don't know, uh, I don't know at all. Student repeated the investigation. After replacing the lamp with a resistor at a constant temperature and then a diode, the student plotted a graph for each component. What is this talking about? I just don't know. Hey, let's go. Tales. Uh, alive is, um, tales alive is the bottom one. Yeah, that's the lamp.
Ron: Um, can you answer it in?
Laura: What do you mean? Start with the top, then diode. Uh, that's the wiggly worm, third one. I don't know. Okay, um. Then filament lamp. D. Nah, I've actually changed my mind about the filament lamp. I'm gonna call that one the straight line.
Ron: Okay.
Laura: And then the resistor is gonna be the tails. Alive. Okay, fuck it.
Ron: 1.7. Figure two.
Laura: You get two marks for that. When there's the three. Fuck off. I had to do three questions. There's only two marks.
Ron: Easy questions.
Laura: I don't know what they mean.
Ron: The figure two shows an ammeter. The ammeter is not connected to a circuit. What type of error does the ammeter display?
Laura: Um. Um. A rand. A positive error. A random error. A random error, Ron?
00:20:00
Laura: Well, it says 0.02, so it's positive in that it's showing some positivity in that it's like picking up what no one's written down. So it's more than it is. Is that what a positive error means? We've never talked about this. This is so wildly in the dark from anything we've ever talked about. Like, my mum is writing a letter of complaint to the school board as we speak, that I've been sent into the lion's den with nothing.
Question number two. What type of error does the ammeter display
Ron: Question number two.
Laura: Fine.
Ron: What do you want me.
Laura: What do you want me to do? You can't just ask me questions about something I have never experienced in my life. Well, you should have taught it to me then.
Ron: Do you mean now?
Laura: Well, you're not allowed to look at me like I'm thick then.
Ron: But if I don't do this, then it's just you doing an examined. Um.
Laura: But you're not even saying anything. A thick look doesn't help the podcast in any way, does it?
Ron: Because it gets this out of you.
Laura: Say something, you coward. Mackie, enough spinning.
Ron: Do you want your bit of help?
Laura: I don't even know. Cause apparently it's gonna get harder.
Ron: I can give you a free bit of help on this one. Yeah, go on, read the question again.
Laura: The ammeter is not connected to a circuit. What type of error does the ammeter display?
Ron: Yeah.
Laura: Zero two.
Ron: It's not connected to a circuit.
Laura: Yeah, yeah.
Ron: So what should it be saying?
Laura: Naught point. Naught. Naught. So it is a positive error.
Ron: Read the options again.
Laura: But.
Ron: Read the options again.
Laura: A positive error, a random error or a zero error?
Ron: Yes.
Laura: Is it a zero? Everything? It should be showing zero. Yes, but that doesn't make any sense because zero would be right, not an error.
Ron: You're so fucking stupid. Zero, uh, because it's zero is wrong. And it's like when your scales is wrong and you tear them. Yeah, yeah. That's called a zero error.
Laura: Well, no one's ever told me that, uh, I would say this was anything but a zero error, because it's not.
Ron: Showing a zero, and it's an error that it's not showing a zero.
Laura: Okay, an error on zero. Then.
Ron: You get it. Why are you writing?
Laura: My brain just immediately discounted that as going like, no. Do you think it's like when I play video games, I have to have my controls inverted? Do you think I just think inverse.
Ron: We think super differently about everything.
Laura: Yeah, yeah. Like, do you think that that ammeter has anxiety? Like, even when nothing is being asked of it, it's functioning and not going ought to.
Ron: No. Um, it gets broken. Right. Random error.
Laura: You said no, I said zero error, you stupid culk. Yeah, like a McCauley Culkin. Singular.
Ron: Right. I'm changing. You get a free bit of help there. Science rate.
Laura: You. Enough. You help me just out of shit.
Ron: You're so dumb, you have to be helped. What are you doing?
Laura: Nothing. Uh.
Ron: Why?
Laura: What do you mean, why?
Ron: Just joking. Mackie, can you stop noncing yourself on the carpet, please?
Which particle in the atom was discovered first in the chemistry exam
Scientists.
Laura: Ah, we had this question yesterday.
Ron: Scientists developed different models of the atom as nude. Mackie, stop it. Developed. New discoveries were made. Which particle in the atom was discovered first?
Laura: This came up the other day, didn't it?
Ron: Came up yesterday in the chemistry exam.
Laura: Should I go for the same thing again?
Ron: How confident I am.
Laura: Never confident. What are you doing?
Ron: Just checking a message. People care about me. Can't pull that face. It's not. Yeah. Oh. It's not like bloody, um, Rob Beckett or something. Just dropped into my dm's m to be like, oh, carry on, Ron. You can do that physics exam.
Laura: I text you all the time.
Ron: Yeah.
Laura: I'm basically like Rob Beckett, except wildly unsuccessful.
Ron: What are you doing?
Laura: What did I go with? Um, I'm gonna go with what I went with before. Electrons and just back myself.
Ron: Thank you.
Laura: They can't ask the same question in physics and chemistry. That's trade's description.
Ron: In an experiment that led to the nuclear model of the atom. Mhm, alpha
00:25:00
Ron: particles were directed at a sheet of gold foil.
Laura: Yep. Rutherford.
Ron: Figure three shows the part.
Laura: Figure three. Young rippersnapper.
Ron: Figure three shows the path of three alpha particles passing close to a gold nucleus.
Laura: Ooh.
Ron: An alpha particle has a radius of 1.7 femtometers.
Laura: What the fuck is a femtometer?
Ron: It's a, uh, really, really small measurement.
Laura: Why is there so much brand new stuff coming up in this exam?
Ron: Because you didn't listen.
Laura: You've never said femtometer.
Ron: We did a whole lesson on femtometer.
Laura: We did not. Because I'd have had a great time talking about feminist metres.
Ron: Femtometers. Um, daddy thinks femtometers. M the radius of a gold nucleus is 4.2 times larger than the radius of an alpha particle. Calculate the radius of a gold nucleus in femtometers.
Laura: Oh, God. Okay. Uh, an alpha particle has a radius of 1.7. Radius, uh, of gold nucleus is 4.2 times larger than that. Okay. That's just a straightforward sum, isn't it? 1.7 times 4.2. Okay. Sometimes I get so creeped out by the question and how many words there are in it. I just can't see that, actually, it's just multiply these two things.
Ron: Sometimes they do just need a little bit of maths.
Laura: Yeah.
Ron: In. Because you could know nothing about any of this.
Laura: And get that. Seven, uh .14.
Ron: Alpha particles are detected by. Are deflected by the gold nucleus. What are the charges on an alpha particle in a gold nucleus? What's an alpha particle?
Laura: I don't know. Uh, where's an alpha particle?
Ron: This we have definitely covered.
Laura: Is that a neutron?
Ron: If it was a neutron, why wouldn't we just call it a neutron?
Laura: That's a great point. I don't know anything about anything. Was an apple pie a proton? No, because then we'd call it proton. It's got a combination of some stuff I just had. No.
Ron: Laura.
Laura: No Laura.
Ron: We've been recording for 24 minutes.
Laura: Yeah.
Question two asks whether a nucleus can be positively or negatively charged
And we're on question two.
Ron: We are on page nine, though, to be fair.
Laura: Uh, creaming.
Ron: Don't you shout creaming at me. Which one is it? Pick one of the fucking answers.
Laura: Oh, God. Can I look at the periodic table?
Ron: Yeah.
Laura: Will that help?
Ron: No, it's not what you need.
Laura: But that'll tell me whether a, uh, nucleus of a. No, it won't, because that won't tell me about the electrons, will it?
Ron: Read the three options.
Laura: An alpha particle and a gold nucleus are both neutral. An alpha particle and a gold nucleus are both positively charged. An alpha particle is positively charged, and a gold nucleus is neutral. Oh, uh, wait. A nucleus can't be neutral. So it has to be an alpha particle and a gold nucleus are both positively charged. Because nucleus can't be neutral. Unless it's got no protons. And none of them have that, do they? So, middle one, Ron.
Ron: Okay.
Laura: It's like the gathering. Read the whole car.
Ron: Yeah. Don't just panic. Grow. Read the question.
Laura: Do you want your trifle yet?
Ron: Why do I have to eat a whole trifle? When you sent me that picture of.
00:30:00
Laura: The trifle, I texted you and I said, do you think it would be funny if you had to eat a whole trifle while we did this exam? And you said, that trifle doesn't look very big. I'll leave it to your comedy judgement. And me with the trifle thought it's quite a big trifle. I think this will be funny.
Ron: All right. But every time you take ages, you have to have some.
Laura: No, because I don't like trifles.
Ron: I don't like trifles.
Laura: Why did you say you would eat old?
Ron: I didn't. I said, use your comedy judge.
Laura: And I have, and I won't be. Well, get me the trifle then, because I hate cream.
Ron: I hate cream as well.
Laura: Well, you have to eat it.
Ron: You should eat, like, some of the pickles from the fridge.
Laura: There's a big trifle. Wrong. You have to eat it with this base.
Ron: Comedy values going up.
Laura: Can, uh, you pick the trifle up a bit with the spoon?
Ron: Wah uh wah. Here's my trifle.
Laura: Okay. All right.
Question nine. Which statement describes the force between the alpha particle and the gold nucleus
Question nine.
Ron: Which statement describes the force between the alpha particle and the gold nucleus?
Laura: Contact force. Force of attraction, force of repulsion. There is no force uh, a contact force, I think. Okay, wait, no, because if they're both positive, then there would be a repulsion. I'm gonna go. Repulsion run.
Ron: Okay.
Laura: Ron. M doesn't like cream. And there's lots of cream in this trifle.
Ron: Comedy gold.
Laura: I'm just gonna poop to death tomorrow.
Ron: I'll be fine. I don't think I'm actually allergic to milk.
Laura: Yeah, only a doctor told you you were.
Ron: I think allergy tests are bullshit.
Laura: Do you?
Ron: I think so, yeah.
Laura: Like crystals.
Ron: Crystals are bullshit? Yeah, sometimes. What do you mean?
Laura: Everything has energy. Imagine if I got big into crystals.
Ron: I can. I can see it for you.
Laura: No, I have quite. Is the trifle bad?
Ron: This? It's all one.
Laura: Yeah, trifle's gross.
Ron: It's not like it's not all one texture, but it's so all one. Um, vary.
Laura: Do you want to put some pistachios in it?
Ron: No. Maybe I'll put this biscuit in there, try and shatter off some shards.
Laura: Um, the next question, Ron, it says which. Which.
Ron: Yeah, I've got to be trifle, so you can do most than it's.
Table one lists different models of the atom in alphabetical order
Laura: Now I've lost where we are. Which alpha particle in figure three experiences the largest force from the gold nucleus? Um, I'm going to go with particle a, Ron, which is a basically doing a hairpin bend off the gold nucleus, uh, where the others are just slightly, like, wisping away.
Ron: Okay.
Laura: Oh, and now it's table time. Table one lists different models of the atom in alphabetical order. Bohr nuclear plum pudding. Tiny spheres that cannot be divided. Which model in table one was developed first? I think it was plum pudding. Okay, probably.
Ron: Which was developed last?
Laura: Well, I don't really remember the other three, but I know Nios Bohr worked with Kenneth Branagh. Wasn't hedged.
Ron: Mm hmm.
Laura: So that by the time you're developing the atomic bomb, you must know what an atom looks like. So I would assume Bohr, but then I don't really know what nuclear refers to. Maybe they just thought everything was. I'm gonna go with Bohr. That feels like a logic that I won't be mad at myself if and when that's wrong.
Radioactive isotopes have different half lives. Which isotope is least stable
Ron: All right, we're on question number three, page eleven. Flying through m. Some isotopes admit nuclear radiation. Carbon twelve and carbon 14 and both isotopes of carbon complete the sentences. The nucleus of a carbon twelve atom and the nucleus of a carbon 14 atom have the same number of.
Laura: And the options are alpha particles, electrons, neutrons and
00:35:00
Laura: protons.
Ron: Really full of trifle already, to be honest.
Laura: Yeah. Do you think you can finish the whole thing? How was the biscuit edition?
Ron: It was the best bit. Biscuits are nice, trifles bad.
Laura: Just put loads of biscuits in.
Ron: That's gonna slow me down.
Laura: We've got ages, m. Uh, the nucleus of a carbon twelve atom and the nucleus of a carbon 14 atomization have the same number of neutrons. I'm gonna say neutrons. Wrong. And a different number of protons.
Ron: Final answer?
Laura: Yes.
Ron: Okay. Different radioactive radio. Radioactive isotopes have different half lives. What does half life mean?
Laura: Uh, okay. It is the time taken for half the nuclei in a sample to decay.
Ron: Okay. Table two shows the half life of some different isotopes of carbon. Which isotope is the least stable?
Laura: Mhm. So it's gonna be the one with the smallest half life, which is carbon 18 coming, uh, in at 0.09. So I'm gonna say carbon 18, Ron.
Ron: Okay, final answer?
Laura: Yep.
Ron: Look at us go.
Laura: I don't know why you're getting credit for it. It's me.
Ron: I taught you all this.
Laura: Am I getting it right then?
Ron: I didn't say that.
Laura: But that's how it feels. Huh? Huh? Did I get that thing wrong about neutrons and protons?
Ron: We have consistently through all three exams.
Laura: Ah. Okay, let's go back. Let's go back. Yeah, I'm allowed to go back.
Ron: Work.
Laura: No, because not to go back to that. I'm allowed to go back. You can go through your exam paper at any point, Ron.
Ron: Go back then.
Laura: Okay, so now I think the nucleus of a carbon twelve atom and the nucleus of a carbon 14 atom have the same number of protons and a different number of neutrons. Right?
Ron: Let me just type that in.
Laura: You're not typing anything. I'm allowed to go back through my exam book.
Ron: Yeah, I'm typing it in. More marks.
Draw one line from each term to an example of the term
Workers in a nuclear power plant love doughnuts must be aware of nuclear irradiation and radioactive contamination. Draw one line from each term to an example of the term.
Laura: Okay, we've got radio contamination and nuclear irradiation. Uh, and the examples are exposure to a beam of gamma rays. Well, that would probably be new. Radioactive contamination, I think. Uh, exposure to ultraviolet radiation from the sun, accidental transfer of plutonium onto a human body. Maybe that would be radioactive contamination. Yeah. And then the fourth one is using a mobile phone. Ron, I'm going to say radioactive contamination is accidental transfer of plutonium onto a human body. And nuclear irradiation is exposure to a beam of gamma rays.
Ron: Final answer?
Laura: Yes.
Ron: We're gonna take a break from this.
Laura: He means the trifle just for people listening. He's not about to just have a recording break.
Why are workers required to boggle? Do you have boggle
Ron: Why are workers required to boggle? Do you have boggle?
Laura: No. I think we gave it back to you, didn't we?
Ron: Yeah. I miss Boggle.
Laura: I'll get you boggle for Christmas.
Ron: Thank you.
Laura: Back to Brighton.
Ron: One of my friends lost one of the dice.
Laura: Hmm.
Ron: Yeah.
Laura: Can you make a new one?
Ron: Make a new dice?
Laura: Yeah.
Ron: Couldn't see how you could get a.
Laura: D six and just put some labels on it with letters on it.
Ron: No. M. Yeah.
Laura: Draw on it with a sharpie.
Ron: That wouldn't work.
Laura: It would.
Ron: I think that would.
Laura: That would work.
Ron: I don't think that would work.
Laura: Get a white d six and just.
Ron: I don't see how it could possibly work.
Laura: Why? You could even just draw a key that you kept outside of the boggle box.
Ron: I don't see how that could work.
Laura: Well, then you're a thickie.
Ron: Why are, uh, workers required to walk across a sticky floor before leaving and paying the power station?
Laura: Um, to make ASMR videos for the Internet? No. The options are to remove alpha particles from their shoes, to remove gamma radiation, or to move radioactive dust. I'm gonna go with dust. It's probably dust.
Ron: What is dust?
Laura: What is dust? Baby, don't hurt me.
Ron: Course or fine.
Laura: Ah. Uh. I can't remember why I went with in the end. Fine. I think it's fine. I watched your sternum puke then.
Ron: Yeah. I don't like trifle.
Laura: Why did you let me spend seven pounds on a trifle?
Ron: I spent seven pounds on that.
Laura: I don't know. I didn't look at the price. I was quite depressed today.
Ron: Yeah.
Laura: I wish I'd kicked that little boy.
Ron: Yeah.
Laura: We should hurt my girl.
Ron: Rage brigade. Go.
Laura: I hate things that upset her. Huh?
Ron: That's, uh, why you've got low self esteem.
The places where people work and live contribute to the nuclear radiation
The places where people work and live contribute to the nuclear radiation. They are exposed.
Laura: Whoa. This table shows the mean daily dose of radiation caused by two different jobs. Aeroplane pilot, 0.072. That's loads because a nuclear power station worker. 0.050.
Ron: Calculate the number of days a nuclear power station worker must work before receiving the same dose that an aeroplane pilot receives in one day.
Laura: Oof. Um. Um. Okay, so is that 0.072 divided by 0.050? Let's see what that sum comes out with and see if that looks viable. Yeah, why not? 144 days. Ron. How are my friends leaving me voice messages right now? Busy.
Ron: The process of nuclear fission takes place in nuclear power plants. The process of nuclear fusion takes place in the sun.
Laura: There's something very funny about that. Good work, AQA.
Ron: Draw one line from each process. Do its fuel.
Laura: Ooh. Okay. Nuclear fission. Uh, so this is power plants. The options are hydrogen, iron, lead and uranium. I'm pretty sure it's uranium. For nuclear fission. The power plant one. Nuclear fusion is hydrogen. I'm sure the sun is hydrogen. It's not iron or lead. I'm gonna go hydrogen. Yeah.
The UK uses renewable energy resources to generate some of its electricity
Ron: We're on to question number four. The UK uses renewable energy resources to generate some of its electricity.
Laura: Not a bloody enough king Starmer.
Ron: This pie chart shows that.
Laura: Mhm.
Ron: Calculate the percentage of energy generated using hydroelectric power.
Laura: Okay, so the pie chart shows 56% wind, 10% solar and 29%, uh, um, biofuel. Carry the one. Uh, that makes that 95%. So it must be 5% hydroelectric. Ron, love that for you.
Ron: You can just do the exam on your own for a bit. I need a wee.
Laura: Oh, well, I need to feed Mackie, so should we have a little pause?
Ron: No, you need to churn through it.
Laura: No.
Ron: And then I'll feed Mackie.
Laura: You won't feed her properly. You'll feed her disgusting things.
Ron: Why would I do that?
Laura: Because you hate her. Huh? And you hate me.
Ron: I don't hate Max.
Laura: Look, she so can't bear to be away from me that she's just sitting in the middle of the floor forlornly rather than on any of the comfortable chairs.
Ron: Because she's a dog.
Laura: No, she never sits on the floor.
Ron: She's so, uh, rapid.
Laura: She's gorgeous and brilliant.
Ron: All right, okay. Pausing here.
Laura: One day more tomorrow. And yet with you, my life has changed. Watch em on em catch them as they fall never lie up another three fall home hear a little slip they're a little tongue one more day until the storm do I follow where she goes? To the barricades of freedom. Will I join my brother? Okay, I've put some tea on.
Ron: Okay. I feel rotten.
Laura: You recording?
Ron: Yes. A remote village in the UK.
Laura: Oh, wrong. You sound dismal. What do you need?
Ron: I need minus trifle. Please take it away.
Laura: No, you have to finish it.
Ron: I can't bear to be near it. It's deflating in there.
Laura: No, you've eaten it.
Ron: A remote village in the UK uses a hydroelectric generator to provide electricity. The
00:45:00
Ron: mass of the water that passes through the hydroelectric generator each day is 2.5 million kilogrammes. The change in vertical height of the water is 15 metres. That's not standard. Form gravitational field strength. Is that. Calculate that.
Laura: Okay? Right. Calculate the decrease in gravitational potential energy of the water. Gravitational potential energy equals mass. Mass of the water is 2500 thousand, uh, times gravitational field strength, which is 9.8 times height, 15. So it's another simple sum using the numbers provided, isn't it, Butler? Yes, Winston. Times 9.8 times 15 equals one. My answer is three. Six. 7500,003, 67500.
Use the physics equation sheet to answer these next two questions
Ron: Okay, use the physics equation sheet to answer these next two questions. M. Write down the equation which links energy, power and time.
Laura: Energy, power, and time. Um hmm. M. Okay, so there's two options on this sheet. We've got power equals energy transferred over time, or power equals work done over time, energy. It's about work done, I think, isn't it?
Ron: What? What are you saying?
Laura: Write down the equation which links energy equals power. Write down the equation which links energy, power and time.
Ron: Yeah, yeah, yeah.
Laura: And on the sheet, yeah, I've got power equals energy transferred over time, or power equals work done over time. Okay, I'm gonna choose power equals energy transfer over time symbol.
Ron: It gives you the fucking symbols. There's energy, capital e, power, capital p and time, little t. Look at the symbols in the formula because trifle makes you evil. Can you see how those are the same three symbols?
Laura: Yeah, fine. Power equals energy transferred over time is what I'm writing down.
Ron: One mark.
Laura: God, there's no space for creativity in physics. I think that's where I fall down.
Ron: The hydroelectric generator transfers electrical power of 3000 watts to the village.
Laura: I don't know.
Ron: Calculate the energy transferred in 60 minutes.
Laura: Wonder where that episode finished. Ron, do you reckon you left it on a cliffhanger halfway through a sentence? Yeah, I believe in the first one because I edited the biology exam. And I believe with that one, I did a clever thing where I sort of started a question and then, like, stopped it. You were like, oh, the next question's about blah, blah, blah. And then the episode ended. And then when I did the second episode, it rewound a little bit so you sort of remembered where you were.
Ron: Oh, wow.
Laura: Yeah.
Ron: That's nice. Uh, profess. I didn't do that for the chemistry one. I've got time to do that for physics.
Laura: You could do. How do you think I'm going to have done, guys, on the physics? If you know your physics, you'll already know what I've got right and what I've got wrong.
Ron: Yeah. Where do you reckon she comes versus chemistry and biology?
Laura: Yeah, um, I've written some more begging. Wow. Ron's really got some pleading going on. So. Yes, cheerfully. It's. It's Sunday the 20 October. It's this week. If you're listening to this in the weekend of release, um, I think. Are they still doing the day tickets where you can just go and see everything for one ticket so you can see us, you can see Olga kok Abaglia, shaman, Pappy's Zoe Lyons, trusty hogs, Margaret Kevin Smith from do the right thing, which is Ron's favourite. He's put it in, um, by accident. Caps lock, my time capsule. I've actually been on that one, so you could go.
Ron: And Tom Scott, I don't know, he's a youtuber. Um, but like a really famous one and he retired, so you can't. He doesn't make new YouTube videos anymore. People. People that listen to us will know who Tom Scott is.
Laura: And I think Garonia Maguire on the way. They were podcast.
00:50:00
Laura: They've got Chesney Hawks as a live guest.
Ron: Fuck Chesney Hawks. He played a piano that John Lennon once owned, according to Fiona Bruce.
Laura: Wow.
Ron: Um. M. Um. Um. Um.
Laura: Thank you, Julian Garrity. Yeah, that's right. We were gonna fall off a cliff edge. And then Julian, he's a straight talking, fast shooting legend. He sees a podcast in need and he comes in to save it. He knows his impulses and isn't afraid of a bit of instant gratification. He signs up, he gets a register announcement, and respectfully, he's a ride as well, packing a fat hog that shoots zip lines that he uses smoothly and skillfully to bring all of his many, many lovers to leg shaking orgasm. He can make the best carbonari you've ever tasted in 18 minutes. Thank you, Julian.
Ron: Thank you, Julian.
Laura: Thank you, Julian.
One of the highlights of my tour has been meeting lab rats
And also, I wanted to say, so my tour is. Is rampaging around the country at the moment, and one of the highlights has been meeting the various lab rats that I haven't met yet because they been too far away from all the live shows we've done.
Ron: Yeah.
Laura: And it's been really lovely meeting lab rats that I'm like, I recognise your name. And then the odd person who's a lurker has come to say hello. Ron's trying not to sleep. I don't even know what that noise was. There's been the odd lurker, Ron.
Ron: Yeah.
Laura: At all. And they've just come over and said, hi, I love the podcast.
Ron: And some of them. Some of them have said some really nice stuff.
Laura: Some of them have said some beautiful stuff. And it's been lovely. Um, but we need to end the episode because Mackie's trying to fudge herself to death now in my arms, and I don't want that. Thank you, Julian, but we are on another cliff.
Ron: If you sign up for the Patreon now, next week, you get your register thing. So go on, guys. Do it, please.
Laura: Okay? We love you. We'll see some of you on Sunday at cheerful earful. And take care of yourselves. Scuttlebug. This is why you must stop scuttling, you beautiful little werewolf.
Should we bring Mackie as well dressed as a werewolf on tour
Should we bring Mackie as well dressed as a werewolf?
Ron: I assumed Mackie would be with you.
Laura: No, she'll be at home with you.
Ron: Why?
Laura: Because I'm going to several cities.
Ron: Yeah, if you always take Mackie, you always take her on tour with you.
Laura: Yeah, but she can't come next week.
Ron: Why?
Laura: I've got to do a BBC recording while I'm there, and she can't come to that. And I have. So here's my week that you're babysitting for. I'm going to London on Wednesday. After the show in London, I'm going up to Crewe as a halfway stop to Glasgow, where I'm doing a daytime recording. On Thursday afternoon in Glasgow, I'm driving from that down to Newcastle to do a tour show. I'm going from Newcastle up to Edinburgh, ready for a tour show there the next day. Have to come out of Edinburgh to afford a hotel to stay in. Back into Edinburgh for three shows the next day, down to Carlisle after those shows to sleep halfway to London, ready for cheerful Ethel on Sunday. Yeah, not really fair to take the dog for that.
Ron: No.
Laura: Plus she wants to see girlfriend of the podcast. You're gonna have to carpet your kitchen. Yeah, you're gonna have to get a big rug in here. Okay. Bye bye, everyone. Is it raining rain? Episode Ron, uh, say class dismissed.
Ron: Pencils, uh, down.
Laura: Oh, yeah.
