Title: Languaging in Hampton Roads Episode 10: The Ebb and Flow of Coastal Carolina Languages Hosts: Prue Salasky and Jill Winkowski Date: Oct. 31, 2024 Length: 34.15 min Publication Frequency: Fourth Friday (approx) of each month Co-hosts Prue Salasky and Jill Winkowski delve into the history and language of Hatteras and Ocracoke Islands, part of the Outer Banks, OBX, of North Carolina, our neighbors to the south and part of our geographical culture in Hampton Roads. They interview two experts on the region. Scott Dawson, whose family traces its roots back to the 1600s on Hatteras, has devoted countless hours to researching the language and culture of the Croatoan people and their early encounters with English settlers. An amateur archaeologist and historian, he has identified artifacts and produced word lists of the Carolina Algonquian spoken on Hatteras Island when the first English settlers arrived in the 16th century. (https://www.coastalcarolinaindians.com/category/research-databases/blair-a-rudes-indigenous-language-collection/). He credits the efforts of English scientist and polymath Thomas Harriot (Hariot) working with Croatoans Manteo and Wanchese for much of what's known today about the indigenous residents, their culture and language. We also learn more about Thomas Harriot and his scientific accomplishments, among the greatest of his generation. Dawson is a founder of the Croatoan Archaeological Society (http://www.cashatteras.com) and also opened a museum on Hatteras to tell a different version of the “lost colony” of Roanoke Island (https://www.lostcolonymuseum.com). . Linguistically, sociolinguist Prof. Walt Wolfram, William C. Friday Distinguished University Professor at N.C. State, places the dialects spoken on the Outer Banks islands as part of the Tidewater diaspora. For example, the brogue spoken on Ocracoke, he says, is closer to that of Tangier Island in the Chesapeake Bay than to that of nearby mainland communities. A scholar of language variation, Wolfram contrasts the vibrancy of the distinctive English dialect of the Lumbee in Robeson County with the rapidly declining use of Ocracoke's traditional dialect. He is also the director of the North Carolina Language and Life Project which documents dialects and speech variations. Listeners can find speech samples for the Lumbee, Ocracoke Islanders and many more by searching for The North Carolina Language and Life Project on YouTube. The changes in language use and dialect over 400 years in these coastal communities first tells the story of English settlement and its impact on indigenous communities. Then ongoing changes reveal shifting demographics and how geography intersects with language and identity.

Historically Thinking: Conversations about historical knowledge and how we achieve it

In October 1569, a captain of a French ship off the northern coast of Nova Scotia was summoned on deck. Alongside was a canoe, and in it were three Englishmen–David Ingram, Richard Browne, and Richard Twide. They claimed to be the survivors of a group of 100 men marooned on the Gulf coast of Mexico by an English slave-trading expedition. From that point, the three of them had walked north for 3,600 miles, making the journey in about a year. Thirteen years later, in August 1582, David Ingram was interviewed and his answers recorded by none other than Sir Francis Walsingham, Elizabeth I's secretary of state and chief of intelligence. Shortly after the publication of his testimony, and ever after, Ingram has been regarded as one of the great liars of his era. He described such impossibilities as large cities, kings carried about in crystal chairs, American natives working with and using iron, and the appearance of penguins and elephants along the eastern seaboard of North America.  Add to that the claim of his extraordinary journey, and little wonder that Samuel Purchas in 1625 observed of his account that “the reward of lying is not to be believed in truths.” But Dean Snow, who once believed like most people that Ingram was at best given to tall tales, has changed his mind about Ingram's journey. In his new book The Extraordinary Journey of David Ingram: An Elizabethan Sailor in Native North America, Snow reconsiders the evidence and recreates the context of Ingram and his journey through an America that just fifty years after his long walk had faded away. Dean Snow is Professor Emeritus of Anthropology at Penn State. A past President of the Society for American Archaeology, he is particularly known for his work on archaeology of native North America with a long-standing focus on the Haudenosaunee (or Iroquois) people. For Further Investigation If you haven't already, get a great overview of David Ingram's era in Episode 303 when Lucy Wooding described some of the characteristics of Tudor England; and while we didn't talk about him in the conversation, Dean Snow has a lot to say about Thomas Harriot. If you listen to Episode 109, you can find out why Thomas Harriot is one of the most fascinating intellectuals that you have never heard of. When Dean Snow referred to Francis Drake escaping from the Battle of San Juan de Ulua in small ship, he was not getting. Drake's Judith was just 5o tons. By way of comparison the Pride of Baltimore II, a modern reconstruction of a early 19th century Baltimore sailing ship, is 97 tons. And that doesn't mean it's a particularly big ship... The Susquehannock town that Ingram visited was probably the "Schultz site"; you can find out more about the Susquehannocks' culture and landscape here. There are apparently a lot of crystal mines in upstate New York, enough for a great vacation.

Paweł Strzelecki opowiedział o czterystuletniej historii hipotezy Keplera, która mówi, jakie jest optymalne (najgęstsze) upakowanie jednakowych kul w przestrzeni trójwymiarowej. Początek tej historii sięga epoki wielkich odkryć geograficznych i wypraw sir Williama Rayleigha, którego asystent - Thomas Harriot, matematyk, astronom i etnograf - układał tabele, podające liczby kul armatnich w stosach o kwadratowej podstawie. W samej końcówce XX wieku, po wcześniejszych nieudanych próbach wielu różnych osób, hipotezę Keplera udowodnił Thomas Hales, matematyk z Uniwersytetu w Pittsburghu. Jego dowód wymaga wprawdzie użycia komputera do obliczeń (jakich - o tym powiem kilka słów), niemniej, został opublikowany w Annals of Mathematics i jest ogólnie akceptowany przez matematyków.

Episode: 2267 Thomas Harriot, England's Galileo.  Today, England's Galileo.

Jake and Dave Yapp‘s Audio Freqs

Here's some recycled material about the moon! You're welcome! The moon has had a massive impact on every culture, so before we get into the science, let's do a whistle-stop tour of what we used to believe about the moon on a spiritual  level. The Aztecs called the moon Mictecacuiatl and believed it travelled through the night sky hunting for victims to consume… As did the Maoris in New Zealand, calling it the ‘man-eater'. The Tartars of Central Asia called it the Queen of Life and Death… All very ‘deathy', isn't it? Early Hindus believed the souls of the dead returned to the moon to await rebirth, and some European stories, not just rather turgid Christmas TV adverts for department stores, tell of a man in the moon - banished there, having been sentenced to death by god for gathering sticks on the Sabbath, because, you know the old saying - Sabbath and Sticks / Do not mix, ok I made that up. Most excitingly, though, everyone's loony - yes - about rabbits. I had no idea. In Chinese mythology, the goddess Chang'e is stranded on the moon after overdoing the old immortality potion, and only has moon rabbits for company. I mean, how high could they jump? Aztec cultures revered the moon rabbit, some Hindus believe the moon is inhabited by a hare, and in Japanese and Korean folklore the Moon Rabbit is believed to be pounding the ingredients for a rice cake, which is presumably, er, rice. Moon rice. Anyway. SCIENCE: The moon's cycles were well understood by… the Chaldea, a small Semitic nation living in a marsh in south-east Mesopotamia, and the Chinese astronomer Shi Shen had also worked out solar and lunar eclipses, roundabout the same time as Anaxagoras in Greece worked out that the sun and moon were giant spherical rocks, and that one reflected the light from the other. Archimedes designed an accurate planetarium, presumably with an adjoining Waxworks and grossly over-inflated ticket price. Ptolemy, around 120AD said that the moon was about 60 earth-radii away and that the moon's diameter was 0.292 of that of earth, honestly, what a nincompoop! Look at the reality! 59, and 0.273! Tchoh! Just to remind you - there weren't any telescopes yet. And, to be honest, almost nothing happened for the next, nearly 20,000 lunar cycles… Until Galileo drew one of the first drawings of the moon from what he'd seen through a telescope. But, if you want to show off at a dinner party, he wasn't the first. An Englishman called Thomas Harriot, who had bought a ‘Dutch Trunke' (ie a telescope, invented the year before in 1608) drew a map of the moon several months earlier, on July 26th 1609. Not only that, he helped Sir Walter Raleigh figure out how to stack cannonballs on ships' decks efficiently which made him think about atomism, and he's credited with bringing potatoes to Britain.  But Galileo worked out that the contours were caused by mountains and craters, from his experience as an artist using chiaroscuro, a theory which went against thousands of years of thought that the moon was perfectly smooth. 1837 was a landmark year. Wilhelm Beer and Johann Heinrich Mådler published books which finally put to rest any fancy ideas people had espoused about vegetation existing on the moon, along with Selenites (moon-people, after the Greek goddess of the moon, Selene [pron: Seleeni]) And other myths have been debunked - apparently, no matter what Aristotle, Pliny the Elder, and the emergency services say, we don't all go a bit loony when there's a full moon (although, well, I can only speak for myself). The first metaphorical rock we managed to chuck at it was Luna 2, a Russian spacecraft on 14th September 1959. It would be ten years and several missions later before Neil Armstrong walked on it and infamously said ‘Wow! I'm walking on the freaking moon, here!' on July 21st, 1969, a mission that used less computational power than you get in one of those birthday cards that plays a tune. In 1967, an Outer Space Treaty had been ratified, ruling that everything in outer space, including the moon, could not be owned by any nation, and not used for anything other than peaceful means. Which is a relief as the American military were eyeing it up for a military base as early as the fifties. Whether we fight or not, on a full moon or not, Ted Nield in his book Supercontinent writes movingly that many, many millions of years from now, when every trace of us, even the radioactive signatures from our nuclear power and bombs has decayed to nothing, when the continents have shifted until our planet is no longer recognisable, our footprints on the moon could be the only thing left to prove we ever existed.

Renaissance Man Thomas Harriot was noted for many things - devising the theory of refraction, creating mathematical symbols including ‘greater than' and ‘lesser than', and being the first person to draw the Moon through a telescope. But the contribution for which he's most remembered is bringing back the potato to Britain - an event commonly credited to 3rd December, 1586.On first spotting the vegetable on Roanoke Island, he wrote: ‘They are a kind of roots of round form, some of the bigness of walnuts, some far greater, which are found in moist & marish grounds growing many together one by another in ropes, or as though they were fastened with a string. Being boiled or sodden they are very good meate.'In this episode, Arion, Olly and Rebecca ask what a ‘versifier' is; come up with a new name for Accountancy; and discover the bizarre means by which Antoine-Augustin Parmentier popularised spuds in France…Further Reading:• ‘The history of the potato: The humble vegetable that changed the world' (Sky HISTORY): https://www.history.co.uk/articles/the-history-of-the-potato-the-humble-vegetable-that-changed-the-world• ‘Thomas Harriot (1560 - 1621) - Biography' (MacTutor History of Mathematics, St Andrews University): https://mathshistory.st-andrews.ac.uk/Biographies/Harriot/• ‘History through the eyes of the potato' (Leo Bear-McGuinness, TEDx 2015): https://www.youtube.com/watch?v=xROmDsULcLEFor bonus material and to support the show, visit Patreon.com/RetrospectorsWe'll be back on Monday!

Foundations of Amateur Radio If you've been around radio amateurs for a little while you're likely to have heard about the Solar Cycle and that it affects radio propagation for HF or High Frequency, also known as shortwave communications. The frequencies in the range of around 3 to 30 MHz, or 100m to 10m wavelength. One of the main ways it's used is for is for long distance or global communication and one of the most common ways that's done is using the ionosphere around the globe to refract a radio signal. In September 2020, the Solar Cycle 25 Prediction Panel, announced that Solar Cycle 25 had commenced in December 2019 and radio amateurs around the globe rejoiced. The first question for me was, why Solar Cycle 25? You might think of the Sun as a stable light in the sky. As it happens, the bright light hides all manner of ferocious activity. One of the measures of this activity is the number of dots observed on the surface of our Star. These dots are called sunspots. As Solar activity increases, the number of sunspots increases. The activity is cyclical, it increases and decreases over time. Each increase and decrease combined is known as a Solar Cycle. On average a cycle lasts about 10.7 years. Simple maths gives you that Solar Cycles started somewhere around 1750. That seems a little strange. Our Sun is 4.6 billion years old. There are paintings on the rocks at Ubirr in the Northern Territory of Australia that are 40 thousand years old. The pyramids in Egypt are 45 hundred years old. The Solar Cycle has been going for a lot longer than the 7 million years there have been humans on the planet, let alone dinosaurs who experienced the Solar Cycle 66 million years ago. Using fossil records we've determined that the Solar Cycle has been stable for at least the last 700 million years. Chinese astronomers recorded Solar activity around 800 BC and Chinese and Korean astronomers frequently observed sunspots but no known drawings exist of these observations. The first person to draw sunspots was John of Worcester on the 8th of December 1128. Five days later, half a world away in Korea on the 13th of December 1128, the astronomers in Songdo reported a red vapour that "soared and filled the sky", describing the aurora borealis in the night sky that resulted from those very same sunspots. In the early 1600's there was plenty of activity around the recording of sunspots. Thomas Harriot appears to have predated Galileo Galilei by more than a year with notes and drawings dated the 8th of December 1610. There's plenty of other names during this period, Father and son David and Johannes Fabricius and Christoph Scheiner to name three, but I'm moving on. The Solar Cycle, was first described by Christian Horrebow who more than a century later in 1775 wrote: "it appears that after the course of a certain number of years, the appearance of the Sun repeats itself with respect to the number and size of the spots". Recognition of the Solar Cycle was awarded to Samuel Heinrich Schwabe who noticed the regular variation in the number of sunspots and published his findings in a short article entitled "Solar Observations during 1843" in which he suggested that the cycle was 10 years. Stay with me, we're getting close to Solar Cycle number One. In 1848 Rudolf Wolf devised a way to quantify sunspot activity. His method, named the Wolf number, is still in use today, though we call it the relative or international sunspot number. In 1852 he published his findings on all the available data on sunspot activity going back to 1610 and calculated the average Solar Cycle duration as 11.11 years. He didn't have enough observations to reliably identify Solar Cycles before 1755, so the 1755-1766 Solar Cycle is what we now consider Solar Cycle number One lasting 11.3 years with a maximum of 144.1 sunspots in June of 1761. Until 2009 it was thought that there had been 28 Solar Cycles between 1699 and 2008 with an average duration of 11.04 years, but it appears that the 15 year Solar Cycle between 1784 and 1799 was actually two cycles, making the average length only 10.7 years. I should also point out that there have been Solar Cycles as short as 8 years and as long as 14 years. With the announcement of Solar Cycle 25 comes improved propagation for anyone who cares to get on air and make noise. The current predictions vary depending on the method used, ranging from a very weak to a moderate Solar Cycle 25. There are predictions for the Solar maximum, the time with the most sunspot activity, to occur between 2023 and 2026 with a sunspot range between 95 and 130. By comparison during the previous Solar Cycle, in 2011 the first peak hit 99 and the second peak in 2014 hit 101. I have purposely stayed away from electromagnetic fields, geomagnetic impacts and the actual methods for HF propagation, I'll look at those another time. I can tell you that we've gone a little beyond counting dots on the Sun to determine activity and we have a whole slew of satellites orbiting our Star doing all manner of scientific discovery, all of which helps our understanding of what's going on in the massive physics phenomenon 8 minutes and 20 seconds away by radio. That said, Solar eruptions are still pretty unpredictable, much like the weather around us. Not because we don't want to know, but because this is a very complex one to solve, much like ionospheric propagation is hard to forecast, much easier to measure actual performance and much more accurate. So, if you want to know how well propagation is going to be today, turn on your radio and have a listen. If you want to know how great it's going to be tomorrow, look at the forecast, but bring an umbrella, or an FT8 transmitter. I'm Onno VK6FLAB.

Harriot's story is tied to SO MANY other notable historic things, including a lot of business with Sir Walter Raleigh. He’s really not a household name like many of his contemporaries, even though he was neck-and-neck with them in terms of discoveries.  Learn more about your ad-choices at https://news.iheart.com/podcast-advertisers

'Looking diligently': calculation an observational scrupulosity in the astronomical work of Thomas Hariot.

In this talk I will look at the role of observational scrupulosity in the astronomical manuscripts of Thomas Harriot (1560-1621) relating to his telescopic observations of the moon, sun-spots, the moons of Jupiter and the 1618 comet. I will reflect on his interest in the observations of Tycho Brahe, and Brahe’s attempts to make his observations and measurements more accurate (particularly his computational tables regarding the ‘leges refractionum’ which aimed to quantify the differences between the real and apparent positions of celestial objects). I will pay particular attention to Harriot’s unpublished (and unfinished) treatise ‘Thomae Harrioti Collectio et comparatio quorundam obseruationum quae putabuntur accuratissimae, quia factae magnis instrumentis et a praestantibus Mathematicis: vt inde iudicium fiat de obseruationum certitudine in genere; et an vlla praestare possit ad minutum’ [By Thomas Harriot. A Collection and Comparison of certain observations, which are considered to be most accurate, because they were made using large instruments and by famous Mathematicians: so that from hence a judgement might be made of the certainty of observations in general; and whether any of them can be done better to the minute] and the criticisms which Harriot offers of the astronomical observations of Tycho and his colleagues, and aim to show the role which accurate computation played in his own astronomical work.
