And evening! It's Laira. Thank you so much for joining us tonight. We are absolutely delighted to be here in the British Library. Can you give them a cheer for letting us do a show? So, to your extreme left, as you can see, she's in the set of people who are the geek songstress. She also has a physics degree. Put your hands together for Helen Arney! Thank you very much. And in the centre of our group, here's our experiment guru. He's the one who loves to push that envelope. It is Mr Steve Walts! And finally, it's Anne. And, finally, it's Anne. And finally, it's our stand-up mathematician and Australian map marker! These are edits that are happening on Wikipedia. So, Greens, our circles are deletes. White circles are edits. The larger the circle, the greater the edit. And as new people join Wikipedia, you see a blue bar across the top. And they've used strings and bells, depending on which type of thing it is. So, you can actually hear what's happening. That's Wikipedia being edited. Isn't that fantastic? The Fenn diagrams are what people are familiar with. Sometimes people think oily diagrams are vendigames. So, I'm going to show you the difference. I'm going to use a group of three things. I'm going to use people who are infestible of the spoken nerd. That's us three. Things, so people who are Australians. And things that have an effect named after them. Now, when you draw a Venn diagram, every single area has to be considered. Every single possible combination of things has to be considered. So, things that have an effect, named after them, that aren't in spoken nerds or Australian. Obviously, the links affect the butterfly effect and so that. Things that are Australian that have an effect, that's doppler, the doppler effect. He's actually Austrian, but I couldn't find the Australians. I'm sure, I'm sure, I'm sure they're all so. I'm sure they're all so. I'm sure they're all so. Do you want to see a seven-way? Multiple nerds, guys, up on the way. There it is. That's beautiful. I love you guys. We've seen some phenomenal bits of data visualization. That has changed the course of history. And I'm going to show you this. This was recently declared to be the worst bit of data visualization ever. The Guardian crowned this, the absolute worst. It's in a guide of how to contact a startup to get a job. This is the section on how to choose a startup. And this is the infographic that was distributed. If you're wondering what the chickens represent, nobody knows. This is from a government presentation I came across. There you are. There's software designed to make charts this complicated, easy for you. What was that? That's reasonable. You've seen what... I wonder if, right, they've taken into account that I literally just... I thought, well, I can check. If I come out of this, if I copy that diagram and put it into Photoshop, I could then go in. I could select. I could use this as a reference point because for a billion, I can get the number of pixels for that. And I can calculate the actual number of pixels that make up this particular... And then I suddenly realise what I was doing with my life. But it is a common problem that you do get this as of the front cover of magazine from the US. There is no rhyme or reason behind the various... This is quite a famous one that was picked up a couple years ago. No rhyme and reason between these. And also, what point are they trying to get across? So those don't match either of the two optional... Maybe there's a third one we're unaware of, right? So these are called bubble plots. I am personally offended by bubble plots. But it gets worse. So here we go. This was a infographic about ways to promote your local business. To promote your local business on a website. There are the classic errors like who needs a scale? And just the word percentage. Just hanging out. No actual percentages involved. We need a mathsy word to put on the label your axis. But it doesn't matter what we're... Going up on the left is the note, the frequency from low to high. So it's low notes all the way up to the highest notes that you can hear. And then along the horizontal axis is time. Yeah. And the different colours are... They're just a code for the intensity of the sound at any one point. And red is more intense than blue. So the most intense is the loudest, the most intense is red. And the least intense is kind of that dark blue. Alright, okay, so let's have a... So if I play it, you've listened to the sound while watching the screen. I think you'll be able to match the two together. So that is a wolf whistling bird. You've actually got a microphone where I can actually have a go at this. And this is what we're doing in the breakout room in the interval. We'll do it in 10 minute chunks. So we'll do three 10 minute chunks during the breakout rooms. You can actually come and have a go at this yourself. But because I'm on stage, I get the first go. Okay, so then we've got a suggestion of what you'd like me to try and reproduce. Hello? Hello? Okay, first of all, the spoken nerd. Or as Matt says, it's feasible of the stuck in need. Oh, it looks Australian, isn't it? It's a lot more colour to it. I think your aura is very green, Matt. I don't even know if you can... Do you like Darth Vader sort of? I have your father. Oh. Luke. I have your father. I am the best one. What about white key? You do some white noise. Like a shhh, some noise. Hopefully, as geeky people, you might know who Alan Turing is. Don't need to go there. Okay, you're good. So, his centenary, and Jonathan Swinton, who's sitting right at the back, had this fantastic idea why don't we, in the year of his centenaries birth, replicate an experiment little known to the public that Alan Turing was investigating, which was number patterns in Sunflowers. So, we, in 2012, got the public to grow Sunflowers and look at the spirals that you see inside Sunflowers. Amazing. What, they sent you the pictures, they sent you the numbers, what happened? They did. Oh, okay. And what was really lovely about you? Did you add these lines? No. They sent you these pictures. Yes, they sent me. What was really lovely is that there, when you involve the public in doing science, wonderful other things happen that we wouldn't do a scientist. So, I thought I would share a few of those things. So, this is Isabel, 10 years old. She showed us how she was counting spirals in her Sunflowers. So, to finish this half before we head out into the break out rooms where there are, I think, one, two, three, four different rooms for you to actually get your hands on all these bits of science and exhibitions. Oh, oh, oh, oh, oh, oh, oh, oh, oh. Darling, it's all wedding anniversary next week. My gift for you is carefully chosen. It's perfect for the couple who have everything. I'm getting us both cryogenically frozen. Be a prevent you from getting cholera. Did you? What did you do in the interview? Are all of you going to go and see the British Library beautiful science exhibition? Yeah, definitely. I'll work here instead. We're all out back. What's the thing you care about more than Vendoragans? How many Twitter followers I have? Okay. Is there anything you care about more than that, Steve? I care about having more Twitter followers than those guys. Well, let's have a look. Let's have a look. So, this is Helen and Steve's Twitter follower account. I know, but you've done a smaller circle there, but that's disingenuous, isn't it? That's so close together. I've done a smaller circle by area. Oh, it is by organ. But me and Helen are doing better than Matt. Surely. Oh. Oh! Wow. You're welcome to be afterwards. Right. We all noticed that the bottom, they all, everyone converges. So when people's hands are down, we're all together. Right. And so if you find someone different height, if you've got a high five, you'd be horribly mismatched, but low-fiving your bang on. No. Right. And so the conclusion is maybe we've evolved to hold hands. Oh. And that ladies and gentlemen is your data. Thank you very much. I think the audience will happily agree with me that an OHP equals OMG. Yeah. All right. So this is why we're not bothering to do PowerPoint slides. Right. Because if you got a, oh, hang on. Frozen. No one has them. Yeah. Why is that? What are you doing? Steve, what are you doing? Oh, you, you could still talk. Oh, sorry. I was speaking left out. Wow. So you brought notepad to the party. Upgrade. I just say live action maths is hard to be. I thought it's one from the ridiculous humour all the way up to kind of mathematical stuff that was even way of my head brilliant. It's really good. You
