Hello everyone! This week on The Cosmic Companion, we explore exploration, exploring the human need to… explore. Later in the show, we’ll be talking with Jon Waterman, creator of Atlas of Wild America from National Geographic.From the dawn of time, humans have been driven by a primal urge: the need to explore. This innate curiosity has shaped our history, propelling us from the confines of caves to the vast expanse of our planet, and beyond.Let’s take a detour down memory lane. Somewhere between 75,000 and 50,000 years ago, a group of mobile Homo sapiens decided to take humankind’s first road trip out of Africa. Even without roads. Talk about wanderlust! This migration wasn’t just a change of scenery — it resulted in a monumental shift for our species, shaping human evolution.Jon Waterman appears on The Cosmic Companion 4 November 2023. Creative Commons 4.0 Attribution 2023 The Cosmic Companion.And who could forget the Ancient Greeks and Phoenicians? They were among the original sea-faring explorers, navigating the Mediterranean long before GPS and Google Maps. Wait. [HOLD EARBUD] I’m getting a notification that we have a surprise guest on the show this week. Yes, (is this real? are you sure, Max? Wow. Ok.) Everyone, in a special chronophone interview from 330 BCE, please welcome famed navigator, astronomer, and all-around curious fellow, Pytheas.  — χαίρετε! Name’s Pytheas. I’m just your average merchant from Massilia… what? Oh, it’s somewhere in what you would call the Provence region of southern France. Anyway, I’ve always had this thing for stories. The wilder, the better. [FULL OPEN] More than 23 centuries before your time, I heard tales of mythical lands, strange creatures, and seas that stretch beyond the horizon. Most folks just dismissed them as sailor’s yarns. No, no. That’s a thing. You’d be surprised how many sailors enjoy macrame…But me? Hearing these stories, I thought, “Why not go check out these legends for myself?” So, I packed my bags and set sail.Now, let me tell you, sailing the Mediterranean is a piece of honey cake. But the Atlantic? That’s a whole different kettle of fish. Literally. The fish are different. Heh heh. Fish… Anyway, there I was, circumnavigating the land you call Britain, or as it went by in its youth, Britannia. I always had a knack for astronomy, and I even figured out the North Star isn’t exactly north. Also, I realized that the Moon plays a role in tides. Good to know when you’re spending months or years at sea.But I wasn’t on the boat all the time. I also got to walk around parts of Britannia, including the legendary tin mines of Cornwall. The people there call themselves the Briton Celtics. I didn’t even know they played basketball.But, up north, the real highlight was the midnight sun. Imagine this: it’s the middle of the night, but the sun is still shining brightly. Great for getting more science done, if not for sleeping outdoors.So there you have it. I’m just a regular guy on an extraordinary journey. Not only did I prove legends of northern Europe true, but I also wound up with a good story or two to tell.Any idea where I can hitch a ride on a rocket? —  Maritime voyages of Ancient Greeks and Phoenicians not only expanded their trade routes but also led to advancements in astronomy, geography, and navigation. Talk about making waves!Then there was Marco Polo, the original globetrotter. [ARE WE TALKING BASKETBALL AGAIN?] His travels to Asia were like the ultimate vacation slideshow, except instead of awkward family photos, he brought back tales of exotic lands and cultures that blew everyone’s medieval minds.[MARCO POLO: Dude. I LITERALLY hung out with Kublai Kahn in Xanadu. No way you’re going to top that!]And let’s not forget about those brave souls who dared to explore the icy wilderness of Antarctica and the towering heights of Mt. Everest. These explorers faced harsh conditions and extreme dangers, but their spirit of adventure and discovery pushed them forward. Their journeys expanded our understanding of these remote places, while testing the limits of human endurance.Fortunately for us all, not all exploration is that strenuous, or hazardous. Next up on The Cosmic Companion, we welcome Jon Waterman from National Geographic to the show. We’ll be discussing the human drive to explore, and his new Atlas of Wild America. Fast forward to the 20th century, and our thirst for exploration led us to the final frontier: space. The Apollo missions were like an interplanetary camping trip — with fewer s’mores and more moon dust. When Neil Armstrong set foot on the moon in 1969, it was a giant leap not just for mankind, but for our collective spirit of discovery.As we look to the future in the 21st Century, the spirit of exploration continues to thrive. With advancements in technology, we’re not just exploring physical spaces but also virtual ones. The rise of virtual and augmented reality technologies, together with artificial intelligence, has opened up new frontiers for exploration, allowing us to experience places and ideas in ways previously unimaginable.As we stand on the precipice of a new era in space exploration — with missions to Mars and beyond on the horizon — we are reminded that exploration is not just about reaching new frontiers but also about pushing our limits and striving for a better understanding of our place in the universe.As we explore the depths of our oceans, the vastness of space, and virtual worlds — we carry with us this indomitable spirit of curiosity. Our future may lie in the words of J.R.R. Tolkien, who said, “Not all those who wander are lost.” So go ahead, pack your bags (don’t forget your towel!) [TOWEL], and let’s set off on our next adventure, becoming a better, wiser, species than we were before we took our first steps away from the familiar. Because at its core, that’s what exploration is all about.The Cosmic Companion is starting the first half of our winter break, taking three weeks off. After all the dumb jokes and crazy costumes this year, we need it! We will come back on 2 December, getting The Inside Story on Planets, talking with physicist Sabine Stanley from Johns Hopkins University. We’ll be discussing her new book, What’s Hidden Inside Planets?

Hello everyone! This week on The Cosmic Companion, we are pondering why Greece is the Word, discussing the birth of science in the ancient world, and what it means for us today. Later on, we'll be talking with Kenny Curtis and Jillian Hughes, hosts of the Greeking Out podcast, and authors of a new book of the same name, from Nat Geo Kids.Once upon a time, in the sunny lands of Ancient Greece more than 25 centuries ago, a bunch of curious folks decided to ask some big questions. "Why does the sun rise?" "What are stars?" "Why do planets move?". They were tired of attributing everything to the whims of gods. Much like overgrown toddlers, they wanted ANSWERS, and they wanted them NOW! (errr… then)...Jillian Hughes and Kenny Curtis appear on The Cosmic Companion 7 October 2023. Creative Commons 4.0 Attribution 2023 The Cosmic CompanionThe Greeks had a knack for asking questions that were way ahead of their time. More than 2,500 years before our age, a woman named Aspasia was known for holding gatherings of some of the greatest minds of her day, including Plato and Socrates. A gifted conversationalist, tales tell that she founded a school for girls, a groundbreaking advance for the era.  Democritus of Abdera had the crazy idea that all matter was composed of individual bits, which we call atoms. Building on the work of his mentor, one day around 425 BCE, he may have just been walking around, minding his own business when he thought, "What if everything is made up of tiny, invisible particles?" Boom! The concept of atoms was born.Then there was Pythagoras who had a thing for triangles. He may have been sitting around one day, doodling triangles in the sand when he realized that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. Mind blown! And thus, the Pythagorean theorem came into existence.During the 4th Century BCE, Hippocrates took one look at medicine and said, "This needs some work." [Not my words exactly, but… Yeah, sure.]He insisted that diseases were not punishments from angry gods but had natural causes that could be studied and treated. This revolutionary idea paved the way for modern medicine.Not long after, Agnodice of Athens practiced medicine dressed as a man, at a time when women were not allowed to be doctors. Thanks to her, laws in Athens preventing women from becoming doctors were overturned. [AGN: You're welcome!]But it wasn't all work and no play for these ancient scientists. Legend has it that Archimedes discovered his principle while taking a bath. He noticed that the water level rose as he got into his tub and realized this could be used to determine volume. He was so excited that he ran through the streets naked shouting "Eureka!" (which means "I found it!"). Now that's what I call a eureka moment!The birth of science in ancient Greece is a story of curiosity, ingenuity and occasional naked sprinting through the streets. The ancient Greeks might not have had all the answers, but they sure knew how to ask interesting questions!With questions come answers, and for a few of each, we're talking with Jillian Hughes and Kenny Curtis about their new podcast and book, Greeking Out, from Nat Geo Kids. ---Now. Let's talk about our friend Pythagoras. Remember him? The triangle guy? Well, his theorem is still used today in everything from architecture to video games. Yes, you heard it right! Every time you play a game of Fortnite or Minecraft, Pythagoras is there, making sure everything looks just right.Next up is Hippocrates, the father of modern medicine. His idea that diseases have natural causes was a game-changer. Today, doctors across the globe follow his principles. So, the next time medicine helps you out, remember to say a silent thank you to Hippocrates (but maybe skip on the leeches and bloodletting).And who could forget Archimedes? His principle helps us design ships and submarines. And yes, he's also the reason why your bathwater rises when you get in. So, the next time you're enjoying a relaxing bath, spare a thought for Archimedes (and maybe keep your "Eureka!" moment to yourself).Last but not least, Democritus' atomic theory is at the heart of modern physics and chemistry. It's why we can build everything from skyscrapers to smartphones. So every time you send a text or take a selfie, remember that it's thanks, in part, to a Greek guy who lived over 2000 years ago.So there you have it! The Ancient Greeks might be long gone, but their discoveries are still very much alive and kicking. It just goes to show that great science never goes out of style!Next week on The Cosmic Companion, we look at Global Warming: It's Not Just Hot Air!. We'll look at the science of climate change, and how our world could change in the coming decades. We'll be talking with Elizabeth Rusch, author of The Twenty-One, telling the story of a group of young people using the legal system to help reverse climate change.Make sure to join us, starting on 14 October, anywhere you see or hear The Cosmic Companion.

Interesting.Well, good evening, everyone! I must say, when I was told I'd be time-traveling, I expected to see the future of Greece, not to land in 'Grease.' However, I am not entirely to blame, by Jove!Here are "The Top 10 Reasons I Thought Grease was Greece:"#10 When my agent said he booked me on a tour of Grease, I thought he said Greece. A natural mistake.#9 I thought I saw young people in togas and a group of Spartan warriors. It turns out they were wearing "poodle skirts" and "leather jackets."#8 All the spontaneous singing and dancing made me think I was near a Greek theatre.#7 I saw chariots without horses. I'm a scientist. Studying those was just natural. #6 One of the horseless chariots had lightning bolts on it. I naturally believed it to be a chariot of Zeus.[ZEUS APPEARSNo. Not me. I wouldn't drive anything that ostentatious.FADE]#5 The sight of people eating in a diner reminded me of symposiums, though I have been told that wine has been replaced with milkshakes. Those are pretty good, honestly. Have you ever tried a flavor called "chocolate?" #4 Hearing about a beauty school dropout, and seeing a woman surrounded by other women in pink, I naturally believed them to be Aphrodite and her priestesses. She still owes me 10 drachma. #3 Watching a dance-off at the local gymnasium made me think of athletic competitions in Ancient Greece. Plato would have loved it.#2 Coming across what I thought was an open-air play, it turned out to be something called a "drive-in movie." I think those are going to be pretty popular in a few decades. #1 And, the NUMBER ONE REASON I Thought Grease was Greece is… [DRUM ROLL] Seeing this teenage drama unfold, I mistook it for a Greek tragedy.OK. I'm ready to go back. Send James Maynard in, already…[FADE. OFF SCREEN:-unintelligible-What do you MEAN the chariot flies? That's ridiculous.]Clear skies!
