This is a Triple J podcast. Hello, welcome to another episode of Science with Dr. Carl. My name is Lucy Smith. This week I learnt that our guts have a circadian rhythm. I didn't know that. You're gonna find out why in this week's episode. Plus, there is a TikTok trend that is yet to come across my feed, but people believe that our third eye, or that region, is magnetic and they've been testing the theory. Does it work? Is it true? Dr. Karl will explain all. That is all on the way. Let's get into it. Dr. Carl is joining us from Perth this morning. Dr. Carl, you've made a new bestie, an underwater bestie. Can you tell us about them?
Uh it's my friend the cuttlefish. And I love it to pieces, and it loves me, and there's five of them in this tank. So we're doing our T V series, How Things Work. This is our third uh series. Um doesn't quite outrate um our good friend Bluey, but it's still pretty good. Um and they changed colour, and finally I've worked out how they changed it, and they've learned a few different things along the way. So firstly, their skin is not just boring skin like ours, but it's actually a remote. Remote control electric electrically driven uh optical display with its own local smarts as well as being controlled by the central brain. And it's got at least three different ways of making colour. And for making the brown colours, um the way it does that is that it um
has little tiny balls of brownish dye, you know, yellow, orange, you red, etc. And they're they're too small to see with the naked eye. They're in things called chromatophores. They're little balls that are too small to see with the naked eye. And then it flattens them out into a large disc and suddenly you can see it. And then there's a different mechanism for the blue colours and they also make white stuff. And you can see the patterns rippling across their body. And this little guy was pushing up against the glass and we were just It was like a cosmic moment, man. I I got besties now.
Really? So did you look each other in the eye?
Uh they got a W shaped eye, so our eye has sort of a roundish aspect. This sort of goes up and down and but what that means is that if you look at it from any angle, it can see you. And the weird thing is they got all their hands coming out of their head, which is different from us, but I still am bonding to my friend the cuttlefish.
Your new bestie the cuttlefish, just beautiful. And if you want to watch the the series, how things work, you can do so anytime over on ABC IV or on ABC Australia's YouTube channel. Let's get into your questions. Dr. Carl's besties from across the nation. We'll start with Roseanne in Nar Melbourne. Roseanne, you got a question about music.
Yeah,
hi
hi doctors. I'm just wondering. Um, I listen to all types of music and you know, there's supposed to be only about eight notes. Um, are we ever gonna run out of a combination of musical notes at all? Or This is a
thing, Roseanne. A lot of people will kind of 'cause you see these copyright cases and these um different things pop up where people feel like songs are too similar or maybe they're for lack of a better term, ripping each other off. And a lot of the justification is often, well, there's only eight notes in a scale. Like how much can we really we've been making music since the dawn of time. How different can it possibly be? Doctor Carl.
Um okay question. Yeah. So so you've got your classic eight notes in an octave, but actually there's twelve notes altogether. And you when you start off at the beginning and you go to the end you've doubled the frequency. So each note is the twelfth root of two. bigger than the note before it. But then in the seventeen hundreds, Bach and all those other people came along and they came up with the well tempered clavier, which means that, okay, mathematically, that's what we want to have, but it doesn't sound right. Let's just change it a little bit. So that's called tempering. So imagine you got your twelve notes and you make uh something that's, you know, ten notes long. Yeah, you've got twelve possibilities.
