ClassicalGuitarShed.com can help you on the journey. If you want to rise to new levels in your playing, it just takes time and strategic work. To play classical guitar well, you need to know: * how to hold and touch the guitar - form and positioning * how to move your fingers and hands - efficient, clean, and fluid * how to learn pieces - reading music, understanding what you see, ingraining, polishing * how to craft the music so it is beautiful - swells and fades, rhythm, touch * how to practice so all these skills improve over time and don't go away At the root of beautiful playing is a solid technique (aka “the way your hands move”). You may have beautiful music in your head, but if your hands can't play it, it won't come out of the guitar. But bad technique puts a limit on your playing. Speed, tone quality, and control can suffer. Good technique gets stronger and more instinctive with every practice. It forms the bedrock foundation for your music. And you may want to understand music so you learn it more easily and it makes more sense. This can help you avoid the excess frustration and dismay that comes with shoddy practice and prolonged confusion. But playing the notes is not enough. Like an actor bring words to life, we breathe life into our pieces. And we can do this in an organized way, day in and day out, reliably. Great musicians can play wonderfully in any mood. They do not rely on emotions. Instead, they create music that affects our emotions. This is a trained skill, not an inborn talent. Playing classical guitar is a long-term study. It's something we do in our homes as part of our days. We play for ourselves, for the quality it adds to life. We may enjoy playing guitar for others, but most of the time we are alone with our work. There are methods and formulas for great practice. We can use our time well so that see more progress. We can fix the problems and erase the mistakes. And we can enjoy conquering the plentiful challenges that classical guitar music offers. If you plan to play classical guitar for any length of time, it is worth it to get help. It's not something we can do on our own, like folk music. I have a structured and organized course to help you play classical guitar.

The evolution of the magnetron — a device for generating microwave radiation — from World War II radar systems to the household microwave ovens illustrates how engineers think about “best.” *Learn More: Companion Book* Explore the ideas in this video series further with its companion book: _The Things We Make: The Unknown History of Invention from Cathedrals to Soda Cans_ (ISBN 978-1728215754) https://www.amazon.com/Things-We-Make-Invention-Cathedrals/dp/1728215757 *Other videos in this series* _Episode 1:_ Building a Cathedral without Science or Mathematics: The Engineering Method Explained https://youtu.be/_ivqWN4L3zU _Episode 2:_ Controlling Turbulence and Evolution: How Engineers Overcome Uncertainty forthcoming https://youtu.be/9RAMqFg7laE _Episode 3:_ The Steam Turbine: The Surprising Relationship of Engineering & Science forthcoming https://youtu.be/-8lXXg8dWHk 0:00 Titles 0:07 Engineering Notion of “Best” The video opens by contrasting an absolute notion of “best” — the Renaissance ideal of da Vinici’s Vitruvian man — with an engineering relative notion as illustrated by the work of industrial designer Henry Dreyfuss, who developed drawings of ordinary people with their far-from-ideal proportions. Dreyfuss’s approach demonstrates that an engineering solution can only be judged based on how it handles the constraints unique to its situation — a balance of cultural forces, societal values, availability of material resources, and even urgency. This means that the notion of best changes with time. 1:04 Cavity Magnetron The cavity magnetron, which powers mobile radar, was created by British scientists in early 1940 in response to fears that Nazi planes would bomb London. This device generates microwave radiation of sufficient power and of the right frequency to detect individual planes. 2:09 First Notion of “Best” The standard of “best” used by the physicist-engineers who developed this magnetron was simply that it worked — prior to this nothing had sufficient power. The device worked in the laboratory, but now it needed to be mass manufactured to equip thousands of British, American and other allies planes and ships with radar. 2:42 Second Notion of Best To mass manufacture the magnetron the British turned to Raytheon and their vacuum tube engineer Percy spencer. For engineer spencer, the notion of best changed: now the issue was one of prioritizing speed of production while maintaining reliability. 3:00 Tolerance Central Problem The slightest deviation in the cavity’s diameter along the length of the cylinder would change the frequency of the radiation and blur the results from the radar. The tolerance was exacting: The diameter of these cylindrical cavities must deviate by at most one ten-thousandth of an inch (about 2.54 microns). 3:36 spencer Magnetron Compared to Prototype A World War II magnetron, likely used in the Pacific Theater, is compared to the laboratory prototype. 4:16 Laminations Bill explains how engineer spencer used a time-honored engineering rule of thumb — break complex problems into smaller, more manageable pieces — by creating thin layers, called laminations, which, when assembled, construct a complete magnetron. 5:44 New Notion of Best for Microwave Oven To reversion the magnetron for an oven the idea of best had to change. At first the goal was to replace the conventional oven and to cook fast. 6:06 1946 Microwave Oven The first microwave oven, which appeared in 1946, was aimed at restaurants, which is a commercial, not a consumer, use. 6:57 New Notion of Best for Consumer Oven To become a household item — a consumer oven — needed a new notion of best as seen in the ads of the first successful consumer oven. They now aimed for a standard 115 volt outlet and an oven that fit onto a kitchen counter and into a household budget. 7:27 Evolution of Oven Magnetron A detailed discussion of the changes from the World War II magnetron to those used in the consumer oven. 9:48 Mythical Story of Microwave Oven Invention Bill mentions a likely apocryphal story, from a popular magazine, of the oven’s invention after a candy bar melted in spencer’s pocket. 10:14 Problems with Mythical Story Bill explains how simple stories like a melting candy bar obscure the engineering method and strips away all the richness of how engineers create. 10:47 Review of Video Series Bill review the engineering creativity discussed in the previous videos in this series. 11:10 Why Understand the Engineering Method Hiding that creativity dissuades our best and brightest from recognizing engineering as a supremely creative endeavor, which robs us of the next generation of mental firepower, the new wave of engineers, who can help solve the problems our world faces. 11:27 Contact info Bill can be reached at bill@engineerguy.com or at 217-689-1461 text/voice (use WhatsApp if outside US) 11:31 End Titles

Menig Amsterdammer is opgegroeid met herinneringen aan een dagje Artis. Toen ging je er misschien heen om enkel de dieren te bewonderen, maar tegenwoordig staat Artis in het teken van nog véél meer dan alleen het dierenrijk. De oudste dierentuin van Nederland viert de hele maand mei haar 185-jarig bestaan, waarbij via speciale activiteiten de mooiste verhalen aan bod komen. Met lezingen, rondleidingen en een belevingswandeling kun je een duik nemen in de wondere wereld van Artis. Ter ere van dit jubileum spraken we vier medewerkers van de belangrijkste onderdelen van Artis: het Park, het Groote Museum, Micropia en het Planetarium. Zij nemen ons mee door de geschiedenis en al het moois wat Artis te bieden heeft. Oorsprong Wat ooit begon als een klein stukje grond waar het ‘Genootschap Natura Artis Magistra’ de natuur dichter bij de burger wilde brengen, groeide al snel uit tot een grote verzameling bijzondere dieren. De wilde dieren werden onder andere gedoneerd door staatshoofden, waardoor het park zich vulde met exotica: zo kon je bijvoorbeeld de inmiddels uitgestorven buidelwolf en quagga bewonderen. Maar Artis is ook met z’n tijd meegegaan. Nu vind je er een kleinere collectie dieren zodat elk dier meer ruimte heeft, en ligt de focus ook op uitzet in het wild. Zo is het park dat ooit alleen diende als dierentuin nu een uitgebreider educatief instituut. Het Park Sinds Job als 4-jarig jongetje voor het eerst in Artis kwam, droomde hij van een baan als dierverzorger. Inmiddels werkt hij 15 jaar in het Park, waar hij twee keer per week de gieren mag verblijden met grote stukken vlees. Bezoekers van alle leeftijden kunnen dit grote eet-spektakel bijwonen, waarbij Job gepassioneerd vertelt over de bijzondere dieren. Zijn grootste wens? Dat hij bij jonge bezoekers net zo’n interesse en liefde voor dieren en de natuur kan opwekken, zoals dat ook ooit bij hem gebeurde. Het Groote Museum Kelly werkt in het oudste museumgebouw van Amsterdam, namelijk het Groote Museum. In het Groote Museum werden vanaf 1855 alle niet-levende dieren verzameld, maar ook fungeerde het die tijd als een soort cultureel centrum, waar de rijkere Amsterdammers zich destijds verzamelden en filosofeerden over de natuur. Nu is, na 75 jaar gesloten te zijn, iedereen hier welkom om te leren over het lichaam, planten, dieren en vooral: hoe al die dingen met elkaar verbonden zijn. Micropia Dat Loek enthousiast wordt van microben is aan z’n grote glimlach af te lezen. Hij omschrijft de micro-organismen als het machtigste leven op aarde; iets waar de meeste mensen zich niet bewust van zijn. Maar dat én meer kun je leren in Micropia. Vergeet hier vooral niet de kus-meter uit te proberen, waar je erachter kunt komen hoeveel microben je eigenlijk uitwisselt tijdens het zoenen… Planetarium Artis geeft niet alleen aandacht aan het allerkleinste ter wereld, ook aan het állergrootste: het heelal. In het Planetarium kun je een reis maken door ons universum, langs de planeten en de verste sterren van de Melkweg. Sterkundige Milo zegt het geheel terecht: als je de natuur snapt, dan wil je ervoor gaan zorgen. En dat is misschien wel de kern van modern Artis: wij kunnen bestaan, doordat alles wat je ziet in Artis ook bestaat. Wij zijn FC Centrum, een FanClub voor onze oude binnenstad. Hier vind je mooie en bijzondere verhalen over het centrum. We zetten de spotlight op al het goede dat onze binnenstad te bieden heeft; bijzondere ondernemers, leuke kroegen, inspirerende buurtinitiatieven en verborgen plekjes om tot rust te komen.

In the next few days, we’ll make history: for the first time ever, an international left-wing movement will be running in elections in two different countries, just a week apart. Our political parties MERA25 will be on the ballot in general elections in Greece, and in the German state of Bremen. In a sense, these two bids couldn’t be more different. In Greece, our party has been in parliament for four years, and we’re led by a former finance minister. In Bremen, we’re building something from the ground up, with a dedicated local group of mostly first-time activists. But both cases are a chance for us to put DiEM25's groundbreaking proposals, radicality and spirit of internationalism to the electorate. So on tonight’s livestream, we’ll be checking in with the candidates and campaign teams. What is electoral campaigning like in 2023? What challenges have they faced? And what’s the historic significance of the coming few days? Tune in and put your questions to us! 0:00 [Introduction] Mehran Khalili 1:20 Yanis Varoufakis 24:48 Judith Meyer 31:45 [MERA25 Bremen] Johannes, Leander and Jan 41:18 Nomazulu 47:48 Questions and comments from the chat 49:07 MERA25 Bremen] Johannes, Leander and Jan 51:32 Erik Edman 1:01:28 Lucas Febraro 1:05:04 Julijana Zita 1:08:33 [Conclusion] Mehran Khalili SUPPORT US --------------------- Join DiEM25: https://diem25.org/join​ Donate to DiEM25: https://diem25.org/donate Subscribe: https://www.youtube.com/c/DiEM25official #Germany #Bremen #Greece

Charles Parsons designed a superior steam engine called a turbine, but was ignored until he crashed a celebration of Queen Victoria's Diamond Jubilee. His turbine still generates most electricity. *Other videos in this series* _Episode 1:_ Building a Cathedral without Science or Mathematics: The Engineering Method Explained https://youtu.be/_ivqWN4L3zU _Episode 2:_ Controlling Turbulence and Evolution: How Engineers Overcome Uncertainty forthcoming https://youtu.be/9RAMqFg7laE _Episode 4:_ The Microwave Oven Magnetron: What an Engineer Means by “Best” https://youtu.be/p8IO9u9IuOs *Video Summary* 00:00 Titles 00:08 Intro To understand the relationship between engineering and science, Bill notes he will share in this video the story of how an engineer created a revolutionary engine by taming the extraordinary power of steam. 00:24 Power of Steam Bill explains that steam can power engines because it expands: one cup of liquid water will expand into 1,600 cups of steam. 00:46 Reciprocating Steam Engines Bill explains that this dramatic change of volume exerts a force that engineers tapped into in the early eighteenth century to drive reciprocating steam engines. He explains the operation of such an engine, focusing on the piston/cylinder where steam expands and the levers that translate the back and forth motion (reciprocating) of the piston to rotating motion. 2:07 Engine Wastes Steam Bill notes that while the reciprocating steam engine revolutionized the world, it wasted much of the steam’s energy. Once the steam has expanded to about sixteen times its original volume it lacks the “oomph,” the force, to overcome the friction of the heavy piston within the walls of the cylinder. And friction in the arms that convert reciprocating motion into circular motion chew up some of the steam’s energy. 2:30 Charles Parsons’s Novel Steam Engine But, in the late nineteenth century a novel steam engine appeared that used the energy from an expansion of an astonishing four hundred and seventy nine times a cup of water’s volume. That novel engine was perfected by Charles Parsons. While a huge leap forward, no one would buy his engine. 2:47 The Turbina & Queen Victoria In frustration Parsons built a ship called the _Turbinia_ to convince everyone of the superiority of his engine. To attract attention he crashed a naval display honoring Queen Victoria’s Diamond Jubilee in 1897. 3:33 Advantages of Parsons’s Engine Parsons’s engine eliminated the need for the piston and cylinder and levers of the reciprocating engine. 3:45 Aeolipile Parsons fused two two ways of using steam to rotate a shaft. The first is the aeolipile, designed by Hero of Alexandria in about 130 BC. 4:47 Branca’s Steam Device In 1629 an Italian engineer, Giovanni Branca, designed a giant boiler shaped like a human head. From its mouth a jet of expanding steam struck a paddle wheel — much like a water wheel — which turned gearing. 5:45 Parsons’s Turbine Bill explains how Parsons succeeded by cleverly combining the action of the aeolipile and Branca’s device by placing thirty wheels along a shaft — half rotated with the shaft, half were affixed to the casing. 8:00 Infinite Complexity This design is simple in concept, but Parsons described the execution as of “almost infinite complexity” because of an astronomical number of dimensions and configurations of wheels and blades and every other design variable in his turbine. 09:19 Why Parsons Succeeded What separated Parsons from the thousands of inventors before him was, he said, the “data of the physicists.” Parsons drew on the data of a forgotten French scientist, Henri Victor Regnault, who spent nearly thirty years documenting the properties of steam. From the data tabulated by Regnault, Parsons could determine that _in principle_ a functioning turbine _could_ be built. 10:15 Science as Rules of Thumb For Parsons, scientific knowledge helped rule out what wouldn’t work, narrow the possibilities of what does, and shorten the path to a solution: scientific knowledge was being used as a rule of thumb. Thus the relationship between science and engineering is that science supplies gold-plated rules of thumb. 10:49 Electricity Generation Although the turbine was a nineteenth century invention, Parsons’s turbine still enables the daily lives of nearly every human on the globe as its descendants generate the world’s electricity. 11:03 Next Video In the next video Bill explores a single word from this definition of the engineering method: What exactly does an engineer mean by “best.” 11:15 End Credits

What if we could actually USE nuclear waste? Subscribe if you love optimistic science and tech stories... Watch Johnny’s explainer on nuclear power here - and subscribe to his channel! https://youtu.be/QzTgZ6kOEM8 Nuclear waste is scary. Maybe you’ve seen it as glowing green goop in The Simpsons, or as a radioactive threat on the news. Either way, you likely know it has been a major block to the use and improvement of nuclear power. Over the last few decades, experts, politicians and the public have had heated debates over what to do with this radioactive material created by nuclear power plants. But what if there were a way to not just store nuclear waste, but actually USE it? This video is about the effort to make electricity out of nuclear waste. Really. It turns out, we developed the tools to do this decades ago. This story is about a technology we left behind and the people who want to bring it back. For this video, I had the privilege of visiting one of the largest and oldest research centers in the US, the Argonne National Laboratory. I’m incredibly grateful to the researchers and staff I met there, and for their time in showing me their work. I also had the opportunity to speak with representatives from Oklo, a company working on new forms of nuclear power, including recycling nuclear waste as fuel. One of the best parts of making Huge If True is meeting and learning from people pushing what we can do in the hopes of improving the world for everyone else. Chapters: 00:00 Nuclear waste isn’t what I thought 02:21 How I got obsessed 03:27 How much energy is in nuclear waste? 06:20 How do you get electricity? 06:50 What is uranium? 07:28 How does a nuclear reaction work? 08:05 Why is nuclear waste dangerous? 08:40 What do we do with nuclear waste? 09:35 How do you make electricity from nuclear waste? 11:21 Why doesn’t the US reuse nuclear fuel? 12:20 Is recycling waste feasible? 13:41 What is Huge If True? Corrections: 07:09 The number refers to the total number of nucleons (either a proton or a neutron) in the atom, not the neutrons alone. A U-235 atom contains 92 protons and 143 neutrons (an atomic mass of 235). The U-238 atom also has 92 protons but has 146 neutrons (an atomic mass of 238). I should have said these *differ* by the number of neutrons in the atom. Thanks to the commenters who pointed this out!

Two examples of how engineers solve problems _before_ they have scientific certainty: How they control whether or not fluid flow is smooth or turbulent, and how they engineer useful enzymes. *Learn More: Companion Book* Explore the ideas in this video series further with its companion book: _The Things We Make: The Unknown History of Invention from Cathedrals to Soda Cans_ (ISBN 978-1728215754) https://www.amazon.com/Things-We-Make-Invention-Cathedrals/dp/1728215757 *Other videos in this series* _Episode 1:_ Building a Cathedral without Science or Mathematics: The Engineering Method Explained https://youtu.be/_ivqWN4L3zU _Episode 3:_ The Steam Turbine: The Surprising Relationship of Engineering & Science https://youtu.be/-8lXXg8dWHk _Episode 4:_ The Microwave Oven Magnetron: What an Engineer Means by “Best” https://youtu.be/p8IO9u9IuOs *Video Summary* 00:00 Titles 00:07 Laminar and Turbulent Flow To illustrate how engineers work their way around uncertainty Bill introduces one of the most complex phenomena in nature yet one of utmost importance to engineers: the transition from laminar to turbulent flow. To illustrate these types of flow he examines the smoke rising from burning incense pointing out that the smoke near the incense flows smoothly (laminar flow) and further away becomes violently swirls (turbulent flow). 00:51 Engineering & Turbulence He notes that to this day a fundamental understanding of when that transition from laminar to turbulent flow occurs puzzles scientists, yet, engineers must know when the transition occurs to control which type of flow occurs. Of prime importance is the smooth, laminar flow of air over an aircraft wing. Yet, without a fundamental scientific understanding of how to achieve that laminar flow we have flown across the Atlantic Ocean routinely since the first commercial passenger flights in 1939. 1:23 Reynolds’s Apparatus Although twenty-first century science cannot fully understand turbulence, a nineteenth-century engineering professor, Osborne Reynolds, built an apparatus to find a formula used by engineers to predict the transition from laminar to turbulent flow. Reynolds learned that a) below a particular flow rate no turbulence occurs, b) that the transition occurs abruptly, and c) that there is an upper limit to the flow rate above which smooth flow cannot be sustained. 3:10 Reynolds’s Explanation To understand this behavior Reynolds compared the flow of water to a military troop. He reasoned that the orderliness of marching troops depends on three characteristics: speed, the number of soldiers in the troop, and discipline. The speed of the troop corresponds to the flow rate of the fluid, and the size of the troop to the diameter of the pipe. And the “discipline” is something called viscosity. It’s the resistance to flow. 3:51 Viscosity: Water vs Honey To understand viscosity, Bill compares the different rates of flow for water and honey: the water flows readily, while higher viscosity honey flows slowly. 4:04 Reynolds’s Number Reynolds gathered three characteristic of fluid flow — the diameter of the pipe, the velocity of the fluid’s flow, and its viscosity — into a single relationship: The diameter times the velocity divided by the viscosity. He observed that when this combination of variables was less than about 2,100 the flow was laminar and above that value the flow could became turbulent. 5:16 Technological Importance of Flow With this relationship engineers could know what to change to achieve laminar or turbulent flow. Bill mentions three designs where engineers want to control the type of flow: mixing pharmaceuticals, cooling steel, and directing the flow of air around a truck. 5:51 Science vs Engineering Reynolds’s approach doesn’t describe turbulence at a molecular level, his description was phenomenological (that is, a description of what is observed). This difference underlines the striking difference between science and engineering: the scientific method strives to reveal truths about the universe, while the engineering method seeks solutions to real-world problems. 6:10 Scientific Breakthroughs Only Change Boundaries We might think that today’s science would subsumes all of engineering. Yet scientific breakthroughs never remove the need for engineering: Humankind developed the engineering method to reach beyond codified scientific knowledge. Instead, the advance of science only pushes out the boundary between the certain and uncertain, and so resets the boundary where engineers work. 6:35 Directed Evolution To illustrate that even today engineers step beyond scientific certainty, Bill tells the story of Nobel Laureate Frances Arnold’s evolution of enzymes that can be used under the harsh conditions of industrial use. 12:01 Next Video Bill mentions that in the next video he will explore the relationship of engineering to science. 12:10 End Titles

Bill reveals the long-lost methods used by Medieval engineers to design stone cathedrals. Methods that required no science, mathematics, or literacy, yet which reveal the engineering method. *Learn More: Companion Book* Explore the ideas in this video series further with its companion book: _The Things We Make: The Unknown History of Invention from Cathedrals to Soda Cans_ (ISBN 978-1728215754) https://www.amazon.com/Things-We-Make-Invention-Cathedrals/dp/1728215757 *Other Videos in this Series* _Episode 2:_ Controlling Turbulence and Evolution: How Engineers Overcome Uncertainty https://youtu.be/9RAMqFg7laE _Episode 3:_ The Steam Turbine: The Surprising Relationship of Engineering & Science https://youtu.be/-8lXXg8dWHk _Episode 4:_ The Microwave Oven Magnetron: What an Engineer Means by “Best” https://youtu.be/p8IO9u9IuOs *Video Summary* 0:00 Titles 0:07 Intro In this first video of the series Bill notes that the engineering method is among the the oldest of human responses to fulfill human needs. 0:28 Göbekli Tepe Bill illustrates this with a brief discussion of the ruins of Göbekli Tepe, a stone structure in southeastern Turkey built thousands of years before Stonehenge and the pyramids. A structure whose use and purpose remains mysterious. The age of Göbekli Tepe highlights that engineering existed long before science — at least what we mean by “science” today. 0:56 Precision of Göbekli Tepe The precision of the placement of the stones in the ruin and their manner of preparation indicate that it is an engineered object. 2:39 Do Engineers Need Science? This leads to the question “Do engineers need science to create.” To answer that question Bill considers the design of Sainte-Chapelle — a stunning thirteenth century stone building. He notes that it was designed and built — as were all medieval cathedrals — by mason who knew no science, or mathematics and who could not even read, nor did they have a measuring stick. 3:13 Gothic Cathedrals: Light The medieval engineers strive to build cathedrals that could house large stained glass windows that could let in sunlight. 3:54 Pointed Arches Medieval masons used pointed arches in their cathedrals to create high ceilings. 4:16 Pointed vs Circular Arches The pointed arch allowed mason to build higher ceiling using less stone, as clearly seen in comparing Sainte-Chapelle to the Pantheon in Rome. 5:00 Width Circular Arch The width of the circular arch grows proportional to its height. 5:29 Width Pointed Arch The width of a pointed arch doesn’t expand because the pointed arch changes shape as it grows taller. 5:39 Proportional Rule Bill explains that these early engineers used a “rule of thumb” inherited from antiquity — one used to build Roman buildings like the Pantheon — to size the supporting walls underneath the arches. The rule was simple: The width of the supporting wall should be between a fifth and a fourth of the arch’s span. 6:51 How Medieval Engineers Sized Walls These early engineers could not perform the mathematics needed to implement this rule, so, as Bill demonstrates, they turned this into an action that required no calculation or measurement with a marked rule. 9:06 Why Arch Divided into Three Section As Bill notes, this is just how the geometry works out. It is the same rule as used to size the supporting wall for a semi-circular arch. 9:52 Rule of Thumb A rule of thumb is the heart of the engineering method: it allowed the masons to build without understand at a deep level the properties of stone or knowing mathematics. 10:29 The Engineering Method This is defined as “Solving problems using rules of thumb that cause the best change in a poorly understood situation using available resources.” That’s a sharp contrast with the scientific method, because these rules of thumb are only guides that offers a high probability of success, but no guarantee. 10:40 Rule of Thumb Never Disproved And, unlike a scientific theory, a rule of thumb is never, in a sense, disproved. That hundreds of cathedrals are still around today, standing for eight or nine hundred years is proof. Instead of being disproved, this rule of thumb for stone became outdated, not wrong, as iron and steel I-beams replaced stone. 11:10 Do Engineers Still Use Rules of Thumb? Bill considers the question “is engineering based on rules of thumb antiquated in our scientific age?” He notes that that line of thought misunderstands the purpose of the engineering method, which is to solve practical problem before we have full scientific knowledge. 11:33 Next Video Bill notes that in the next video he’ll explore how engineers work their way around that lack of scientific understanding, how they overcome uncertainty. 11:45 End Titles

ClassicalGuitarShed.com can help you on the journey. If you want to rise to new levels in your playing, it just takes time and strategic work. To play classical guitar well, you need to know: * how to hold and touch the guitar - form and positioning * how to move your fingers and hands - efficient, clean, and fluid * how to learn pieces - reading music, understanding what you see, ingraining, polishing * how to craft the music so it is beautiful - swells and fades, rhythm, touch * how to practice so all these skills improve over time and don't go away At the root of beautiful playing is a solid technique (aka “the way your hands move”). You may have beautiful music in your head, but if your hands can't play it, it won't come out of the guitar. But bad technique puts a limit on your playing. Speed, tone quality, and control can suffer. Good technique gets stronger and more instinctive with every practice. It forms the bedrock foundation for your music. And you may want to understand music so you learn it more easily and it makes more sense. This can help you avoid the excess frustration and dismay that comes with shoddy practice and prolonged confusion. But playing the notes is not enough. Like an actor bring words to life, we breathe life into our pieces. And we can do this in an organized way, day in and day out, reliably. Great musicians can play wonderfully in any mood. They do not rely on emotions. Instead, they create music that affects our emotions. This is a trained skill, not an inborn talent. Playing classical guitar is a long-term study. It's something we do in our homes as part of our days. We play for ourselves, for the quality it adds to life. We may enjoy playing guitar for others, but most of the time we are alone with our work. There are methods and formulas for great practice. We can use our time well so that see more progress. We can fix the problems and erase the mistakes. And we can enjoy conquering the plentiful challenges that classical guitar music offers. If you plan to play classical guitar for any length of time, it is worth it to get help. It's not something we can do on our own, like folk music. I have a structured and organized course to help you play classical guitar.

Since 1823, the Union has been promoting debate and discussion not just in Oxford University, but across the globe. The Oxford Union is deeply grateful and encouraged by the messages of support in response to our determination to uphold free speech. During our 200 year history, many have tried to shut us down. As the effects of self-imposed censorship on university campuses, social media and the arts show no signs of dissipating, the importance of upholding free speech remains as critical today as it did when we were founded in 1823. Your support is critical in enabling The Oxford Union to continue its mission without interruption and without interference. You can support the Oxford Union here: https://oxford-union.org/supportus

Miss Marple has a remarkable nose for danger. She is a rat, and she detects land-mines by smelling them. She was born in the training lab of the Belgian company, Apopo, in Tanzania. Here African Giant Rats - the size of a cat - are taught to sniff out explosives hidden in the ground. After a year’s training she is sent on her first mission to neighbouring Mozambique, whose 30 years of war have left millions of mines hidden in the earth. A whole unit of rats walks delicately back and forth over the minefields, attached to lines. When they’ve finished, the fields are safe again. Hundreds of lives have been saved, thousands of crippling injuries avoided. Miss Marple is a true hero rat!. --- Welcome to the official Get.factual youtube channel! 🌍 We are a documentary streaming channel covering history, science, technology, and nature.

This photo is the largest catalog of stars ever collected by a single instrument. It captured 3 BILLION stars in the Milky Way and takes up 10 terabytes of data. But it doesn’t just show stars — it also captured cosmic dust, and here’s why that’s important.
