• 86: Eyevolution 2 Eyelectric Boogeyeloo & Digital Piracy w/ Sabrina Cruz

  How many eyes do these animals have, and more importantly what are they doing with them? And how long has copyright piracy been around, and would YOU download a car? Also Ella finally drops her fake british accent.Images we Talk About:Bullfrog Parietal EyeBumble Bee OcelliScallop EyesScallop Eye MirrorsThe Home Taping is Killing Music LogoTimestamps:(00:00:00) Intro(00:04:01) Eyevolution II(00:56:16) Digital Piracy(01:45:06) OutroSupport us with a Max Fun Membership!Join our Discord!We also learn about: How many jingles does this man have up his sleeve?? 2 eyes or not 2 eyes, what do you need glasses for - to see boobs? why have an odd number of eyes when it’s a BOGO deal developmentally, even more amazing than his eye of agamoto - Dr Strange has 2 camera eyes, “I grow fearful of the untrue eye”, bull frogs can’t doom scroll, the pineal eye is a skylight to the pineal gland, ommatidia means little eye, each compound eye only sees one image from the thousand of ommatidia, this is Caroline’s first eyevolution rodeo - we can’t answer all the questions, now you can be annoying correcting people about bug vision, ocelli are also called little eyes, triangular ocelli flight stabilization, Robobee, ocelli are useful because they’re auxiliary, they’re a fast different readout, there are so many more interesting sci fi choices for eyes, maybe they evolved ocelli to not crash when they see a sexy bug, having zero eyes would be going to far, oh wait nevermind, where we’re going we don’t need eyes, “not the implications”, well I’ll answer one of those questions, what do you need eyes for looking at boobs? YEAH I DO ACTUALLY, he complex eyes like a telescope of scallops, THEY DON’T EVEN HAVE A BRAIN, have we gone too far? the living square mirrors in scallop eyes, no one believed scallop TV would work, fair use and fair dealings, early book sellers were book copiers, authors did not make profits on early copies, Martial was the first person to be reposted on 9gag, the library of alexandria operated like OpenAI, book publishers after the printing press were like Universal Music Group - concerned over their rights - not artists, crown approved ABC books, the mid 1600s is the first use of piracy of intellectual property, ruining vinyl records with the cassette tape skull and crossbones, the 2013 Hugh Jackman Oscars performance, Napster’s origins and Metallica’s not so metal killing of it, Piracy was a technical and social phenomenon, YOU WOULDN’T STEAL A FONT, video game antipiracy that reminds you of the creative mind behind the product, none of this is legal advice, the cost of piracy is easy to calculate but the benefit is impossible to measure.Sources:The Parietal EyeCompound EyesHolger Krapp's Fantastic Paper on Ocelli2022 Paper on OcelliOtacilia KhezuThe Scallop's EyesScallop TVEd Yong on Scallop EyesPiracy sources coming soon!

• 85: David Bennett & Why Humans Like Harmony in Music

  What is it about harmonies in music that just sounds so good? Can science (and our amazing musical guest David Bennet) help us get to the bottom of it?Timestamps:(00:00:00) Intro(00:06:24) Why do we like Harmony?(00:56:10) Our Music Theory Questions(01:24:04) OutroSupport us with a Max Fun Membership!Join our Discord!We also learn about: Listening to Carly Rae Jepsen academically, the musical expert said Caroline has good music taste, I’m down hereeeeee, harmony is just the interaction of any two notes, Tom thinks about high school choir harmony all the time, even babies like harmony, even the oldest flutes have the same holes in them, octaves are so similar we call them the same note, watchmojo ranking of intervals, Carly Rae Jepsen - It Has Many Notes!, a spicy dissonant interval can be good in moderation - like a spicy seasoning in food, Tom is just grinning getting to ask these music questions, we invited you as a guest and you bring this dissonance to our home?? the messy sounding tones match to messy looking ratios, why can we even distinguish pitch? we use pitch in communication so much, animal sounds are the only things that make pitch, animals can recognize intervals, we call bird song song - but to them it’s probably more like language, it sounds cheesy - but in every human voice there’s a harmony, we’re asking the question backwards - we needed to understand harmony to be able to decipher a pitch, hearing the difference between notes IN YOUR HEAD, what we hear in our head is different than the world around us, harmonies are audio cheesecake - something we evolved to enjoy pumped to the max, “we can make cheesecake with our mouths”, cheesecake is just molecules, did you not have to learn human evolution in music school? oh my guilty pleasures are Tchaikovsky’s later works, Ella humble bragging about her spotify wrapped, this is going to come off as hostile but hasn’t enough already been said about the Beatles, how different generations experience the Beatles, more like DavidLegoStopMotion, it took 5 years after a dissertation on how to have a career as a musician on youtube, try song ideas and listen to them later, music theory is Descriptive not Prescriptive, liking technical music, the only way you’ll practice is if you enjoy it, the dopamine hit from the cheesecake of practice, can you send that advice to my mom 10 years ago, but you did practice… yeah, teenagers are good at learning instruments because they have free time, start learning music with the music that you love, learning sheet music at the same time as playing is like learning to write as you’re learning to speak, you learn to write after you’ve practiced speaking for years, you’re full of good ideas David who knew.
