Meter? …or Metre?

↓ More info and sources below ↓

Why is a meter a meter? The meter is the world’s ultimate measure, but how did it become “the” meter? What is this measurement based on? The story of this revolution in measurement traces its roots to the French Revolution. Scientists decided that an equal and united people should have equal and united measures. So they sent a pair of young astronomers out to measure the world, and invent the meter. Little did they know they’d find nothing but war, deception, and strife along the way. As a result of this ill-fated mission, the meter carries an error that still persists today. Still think the metric system is so perfect?

This episode would not have been possible without one incredible book: “The Measure of All Things” by Ken Alder.
There’s so much more to this story that we couldn’t fit in the video, and this book has it all. War, madness, deception, shame, spies, the dawn of the Enlightenment, the birth of modern economics, lots more beheadings… Highly recommended!

This video shows the most spoken languages in the world, between the years 1900 and 2023.

It is difficult to define what constitutes a language as opposed to a dialect. For example, Chinese and Arabic are sometimes considered to be single languages, but each includes several mutually unintelligible varieties and so they are sometimes considered language families instead. Conversely, colloquial registers of Hindi and Urdu are almost completely mutually intelligible, and are sometimes classified as one language, Hindustani, instead of two separate languages. Such rankings should be used with caution, because it is not possible to devise a coherent set of linguistic criteria for distinguishing languages in a dialect continuum.

There is no single criterion for how much knowledge is sufficient to be counted as a second-language speaker. For example, English has about 450 million native speakers but, depending on the criterion chosen, can be said to have as many as 2 billion speakers.

There are also difficulties in obtaining reliable counts of speakers, which vary over time because of population change and language shift. In some areas, there is no reliable census data, the data is not current, or the census may not record languages spoken, or record them ambiguously. Sometimes speaker populations are exaggerated for political reasons, or speakers of minority languages may be under-reported in favor of a national language.

This chemistry video tutorial explains the concept of heisenberg's uncertainty principle in a simplified way. His principle applies mostly for small particles and events. As the uncertainty in the position of a particle increases, the uncertainty in momentum decreases. This video contains some math practice problems that illustrate Heisenberg's uncertainty principle.

Earth’s climate is changing in a big way, and it’s because there's more carbon dioxide in the atmosphere than at any point in our species’ history. But Earth’s climate has changed before. How do we know that this time we’re the cause? We know thanks to tiny bubbles of ancient atmosphere trapped in ice. #climatechange #globalwarming

Preparing a child for kindergarten can be a daunting task for any parent. Beyond the challenges of managing separation anxiety, some may also try and get their children “up to speed” by teaching them the alphabet or how to count from 1 to 10. For families whose first language is not English there are also language and cultural barriers to contend with. But what are the most important skills on day one? In Portland, Ore., a kindergarten preparedness program offers parents strategies to help prepare their children to hit the ground running. Teacher Donna Shinagawa shares six tips with us.

Math riddles are a fun way to train your brain: they combine mind-sharpening math and puzzles that develop analytical thinking. Few of us care about the agility of our minds while we’re still young. But math brain teasers won’t let your brain grow weak and will help you keep a sharp mind at any age.

Remember to keep track of your correct answers to check yourself at the end! If you solve 0 to 10 riddles, you probably didn't pay much attention to math at school? Start with the easiest puzzles and try to crack at least one a day - soon, you'll see the result! If you have 11 to 24 correct answers, you're likely to use math now and then in your everyday life. And if your score is 25 to 31 solved riddles, congrats! You must be some math genius!

President-elect Donald Trump ran on a pledge to abolish the U.S. Department of Education. After his election victory, a flood of educators and activists have asked the same question: Can he really do that?

The short answer: It’s possible, but he couldn’t do it alone. Members of Congress would have to approve a plan to reorganize federal agencies, and Trump would face a lot of hurdles in winning their support.

And even if the agency closed, its responsibilities—like administering Title I funding, the Individuals with Disabilities Education Act, and student loans—would be transferred to other federal agencies.

Conservative pledges to shut down the Education Department date back to the presidency of Ronald Reagan, shortly after the agency’s 1979 creation. None have followed through on that promise—so far.

A Feynman diagram is a picture of what happens when particles interact with each other. I in this video I explain what you need to know to understand Feynman diagrams, show you what all the particles in the standard model are, as well as which lines we use to represent them. And the general rules the fundamental particles follow as well as which particles take part in interactions via the fundamental forces.

This is a replay of EdWeek's webinar, "Joining Forces: Tapping Teacher Specialists to Serve All Students." Adams 50’s Steve Sandoval—a 2016 Education Week Leader to Learn From—created an “interventionist framework” out of frustration that his district's talented education specialists were isolated by separate certifications, regulations, and funding streams. Learn how the Adams 50 school district in Colorado brought together an array of education specialists—who typically work only with select students—to use their teaching strengths to benefit all students. ____________________

Clase de español - El alfabeto

En esta clase aprenderemos el alfabeto, con ejemplos para cada una de las letras. "N" de Navarra, "M" de Madrid, "O" de Oviedo, "P" de Pamplona, "S" de Soria

En España, cuando tienes que deletrear alguna palabra, muchas veces se nombran las letras junto al nombre de una ciudad para evitar confusiones. Si tuviéramos que deletrear "SOL" por ejemplo, sería: "S" de Soria, "O" de Oviendo y "L" de león.

El alfabeto o abecedario Español, es el único del mundo que incluye la Ñ, que los españoles suelen usar como representación de su idioma.

También veremos ejemplos de un sonido muy complicado para quienes quieren aprender Español, la doble letra "R", como en perro.

In which John Green teaches you about the conflict in Israel and Palestine. This conflict is often cast as a long-term beef going back thousands of years, rooted in a clash between religions. Well, that's not quite true. What is true is that the conflict is immensely complicated, and just about everyone in the world has an opinion about it. John is going to try to get the facts across in under 13 minutes.
