All this today on Something You Should Know.
Ah, the Regency era. You might know it as the time when Bridgerton takes place, or as the time when Jane Austen wrote her books. The Regency era was also an explosive time of social change, sex scandals, and maybe the worst king in British history. Vulgar History's new season is all about the Regency era, the balls, the gowns, and all the scandal.
Listen to Vulgar History, Regency era, wherever you get podcasts. Something you should know. Fascinating intel. The world's top experts. And practical advice you can use in your life. Today, Something You Should Know with Mike Carruthers.
Have you ever not gotten enough sleep one night and figure, well, you know, I'll make it up on the weekend? Is that a real thing? Does that really work? Well, that's what we're going to start with today on this episode of Something You Should Know. According to Dr. Janet Kennedy, she's a psychologist who treats people with sleep disorders, the idea of catching up on your sleep doesn't work.
Sure, if you only got, say, two hours of sleep one night, you may want to sleep in a bit the next day, but in the long term, it's really not about the math. If you are chronically sleep deprived, you will never make up all the hours of sleep you've missed, and you really shouldn't try. It's about your routine. When you disrupt a regular sleep routine by staying up late, you confuse your body.
You may have to take a nap or drink caffeine to stay alert, which causes more confusion to your body. In fact, it turns out you cannot catch up on sleep, but you can even it out. And you do that by sticking to a regular sleep schedule as best you can, weekends included. And that is something you should know. Popular music is often called the soundtrack of our lives.

Chapter 2: How has technology changed the way songs are created?
And sometimes they're really good songs. And other people are able to crank out song after song after song. And why the difference?
It's a very difficult thing to have any hit songs. It's basically an impossibility to have multiple hit songs. And to become a legend requires a combination of skill and luck that almost no one is blessed with. So I always think, when I think about one-hit wonders, I often... think we think about them in a bad light or like, oh, you know, they weren't good enough to have another.
Honestly, they were lucky enough to have one hit, which is more than 99.9% of musicians can say. But it is just very, very difficult to stay on top for so long.
I love that because you're right. We look at one hit wonder people as almost as a failure. Like you had your chance. Look, you were right there on top and you blew it. When in fact, most people never get there. Are you able to look back at the history of popular music and point to a couple of songs that really...
either change the direction or turbo boosted something that were really big deals in the business.
there are tons of hits that come to mind i guess i can highlight a few of course you could point to i want to hold your hand by the beatles it really kicks off the british invasion it makes the style of rock music popular and the beatles end up being tremendously influential they didn't invent this but the beatles became so popular that if you wanted to be taken seriously
after a certain point you had to be writing and performing your own songs that was not a completely new idea but the beatles really turbocharged that idea in the 70s this song called rock your baby by george mccray comes to mind because it's sometimes called the first disco song i mean you could argue about that but
If you think about it in the context of disco, which was this revolutionary genre of music that was popular for about a decade, it's a genre that really turns many things on its head because the star in the disco community was the DJ, whereas previously the star in the music world was whoever was performing the song. But now Someone that could make hits was a guy that was just spinning records.
This was sort of a revolutionary idea. And I think Rock Your Baby by George McRae is a good example of what was to come throughout the 1970s. And I'll just give one, I mean, like I said, there's tons of examples. One other that comes to mind is... In 1991, there was a number one hit by a rap duo called PM Dawn called Set Adrift on Memory Bliss.

Chapter 3: What trends influence the themes of popular music?
I'm going to get you on MTV. I'm going to get you on radio. Wouldn't always work. But Clive and his record label compatriots held the keys to the castle. Now you can build an audience for yourself online and then a record label will sort of come in at the 11th hour and be like, all right, we're going to give you a deal. We're going to pour gasoline on this fire.
So if you want to be, you know, Taylor Swift or the biggest possible superstar, you still need the know-how of a label, but you can get your music out there. You can get it heard and you can build a legitimate career without going through a label. So we live in a completely different world than we did a few decades ago.
And the people who put music out online and some people become stars as a result, but probably most people don't. So what's the difference? What is it? Is it the music is just so much better? Or what is it that makes some online musicians successful?
Another good question that if I had the answer to, then you'd probably be interviewing me about my successful music career. But I think there are a couple things that we can point to that are different. A, because it's so easy. I mean, you certainly have more amateurs who are putting out music. And if you are talented, it's a little bit easier to cut through that noise.
At the same time, it's never always been just about the music. And in this day and age, the easiest way for people to get attention is on social media.
How, if at all, how is the technology by which music is delivered to people, which is so very different than it used to be, how has that technology impacted the way the music is created in the first place?
I think you often hear people talk about how songs have become shorter in the streaming age and there are incentives for that because the way streaming works is that you get paid after a 30 second stream and you get paid more if you command a bigger piece of the streaming pie. So if you have a bunch of really short songs, you'll command a bigger piece of that pie, you'll get paid out more.
And one thing I often think about is artists respond to incentives and that musical evolution is often downstream of technological innovation. What that means is that artists are responding to the incentives created by different technologies. And I bring up shorter songs because I think people do talk about that a lot.
But something that I came across is actually song titles have gotten shorter too. And this may seem like a weird, small thing to bring up, but I think it's a great example about how artists are influenced by the technology that they're interacting with. The reason that titles have become shorter, it was a trend that started in the early 2000s and then accelerated in the last decade.

Have you ever wondered, why are rainbows in the shape of a bow? Why do sunflower seeds, if you ever look at the seeds in the flower, why do they arrange themselves in such perfect spirals? Why are there some left-handed people, but not very many? The answers to questions like these become even more intriguing when you look at them through the lens of mathematics.
Eddie Wu is here to show just how much of the world is shaped by math, but we hardly notice it. Eddie is the head mathematics teacher at Cherry Brook Technology High School in Sydney, Australia, and back in 2012, he began recording his lessons and posting them on YouTube. creating WooTube, and he now has more than 600,000 subscribers and over 33 million views.
He's also author of a book called It's a Numberful World, How Math is Hiding Everywhere. Hi, Eddie. Welcome to Something You Should Know. Thanks for having me, Mike. So let's start with a rainbow, because every time you see a rainbow outside, it's always in the shape of a half circle, in the shape of a bow. But why that shape?
so i actually was very recently up in a plane you can see that actually the shape of a rainbow is not just you know sort of half of a circle it is actually a full circle and what is happening here is one of these most phenomenal ideas that i've ever experienced which is that i want you to picture mike uh the rain has just been falling for the last couple of hours but suddenly it's it's stopped the clouds are starting to part
And the sun is beginning to shine again. All right, what is happening in this moment? Well, firstly, even though the rain has stopped, there is actually still a lot of water in the air. All of these hundreds of millions of droplets kind of still suspended in the atmosphere.
And each one of those individually acts like a little prism and a little mirror that reflects light from the sun around Earth. all of the different directions. So every one of those hundreds of millions of raindrops in the air is doing that. It's refracting the light into its different component colors. But a raindrop is not a triangular shape. It's round.
And so what will happen is that light will refract but it will rebound on the inside of that roughly spherical raindrop and it will go back, it will reflect back in the direction roughly that it came from. Now, there are some of those raindrops in the air out of those countless number that will reflect back to your eyes and to mine that particular spectrum and all of those particular raindrops
are going to be in the shape of a cone. Now, if you look at a cone from the top, you don't see the whole sort of, you know, ice cream cone shape. You actually see the cross section of a cone, which is a circle. And that circle is the shape of the rainbow that you and I see. It's just that we usually only see half of it because the horizon is blocking its path.

Chapter 5: Why do some songs become hits while others don't?
And so every snowflake begins with a hexagon and as other water molecules grab on in the air and join the party, they form outwards in this symmetrical, beautiful shape. So again, it's microscopic. You almost wouldn't believe that it's there, but mathematics is the engine that makes our entire world run.
Well, it's always fun to look at life, different parts of our lives through the lens of math, because often the explanation is so surprising. I've been talking to Eddie Wu. He is the head math teacher at Cherrybrook Technology High School in Sydney. He is the creator of WooTube, that's W-O-O-T-U-B-E on YouTube, and he has over 600,000 subscribers.
And his book is called It's a Numberful World, How Math is Hiding Everywhere. And there's a link to that book in the show notes. Thanks, Eddie.
No, the pleasure is all mine, Mike. Thank you so much for letting me have the opportunity to speak with your audience.
So in the workplace, there are 12 basic skills. You're likely excellent at a few of them, mediocre at several of them, and really bad at a couple of them. So let's see if you can identify your weakest ones. Here are the 12 skills.
Self-restraint, working memory, emotion control, focus, task initiation, planning and prioritization, organization, time management, defining and achieving goals, flexibility, observation, and stress tolerance. And you may want to hit that little rewind thing and play that list back. Because here's why it's important to identify your weakest ones. They're not very changeable.
Yes, you can improve on them, but if you're really bad at some of these skills, it's going to be very hard to get good at them. So they should not be part of your job description. Instead, your job should include the two or three skills that you're really great at. Interestingly, in a survey of 2,000 workers, the majority of people said their job did not play to their strengths.
This is all according to Chuck Martin, who wrote a book called Smarts. And that is something you should know. I certainly, I really do appreciate the fact that you take time to listen to this podcast. It means a lot. And if you would like to share it with someone you know, that would mean a lot too. I'm Mike Carruthers. Thanks for listening today to Something You Should Know.
The Infinite Monkey Cage returns imminently. I am Robert Ince, and I'm sat next to Brian Cox, who has so much to tell you about what's on the new series. Primarily eels. And what else? It was fascinating, the eels. But we're not just doing eels, are we? We're doing a bit. Brain computer interfaces, timekeeping, fusion, monkey business, cloud, science of the North Pole, and eels.
