Développement du cylindre Hilbert and Cohn-Vossen wrote about the cylinder: "The circular cylinder is the simplest curved surface. It can be obtained from the simplest curves -the straight line and the circle- by moving a straight line around the circunference of a circle while keeping it perpendicular to the plane of the circle. Another way to get the cylinder is by rotating a straight line about an axis parallel to it. In this page, the cylinder will be closed by two parallel planes perpendicular to the axis. The main interest of this page is to see how a cylinder can be developed into a plane. The lateral surface area of a cylinder is the area of a rectangle. To calculate the Total Surface Area of a cylinder we must add the lateral surface area plus the top and bottom circles (the two circles that make up the ends of the cylinder). Do you remember how to calculate the volume of a cylinder?
Family Educational Rights and Privacy Act (FERPA) Family Policy Compliance Office (FPCO) Home The Family Educational Rights and Privacy Act (FERPA) (20 U.S.C. § 1232g; 34 CFR Part 99) is a Federal law that protects the privacy of student education records. The law applies to all schools that receive funds under an applicable program of the U.S. Department of Education. FERPA gives parents certain rights with respect to their children's education records. Parents or eligible students have the right to inspect and review the student's education records maintained by the school. Schools may disclose, without consent, "directory" information such as a student's name, address, telephone number, date and place of birth, honors and awards, and dates of attendance.

Digital Bodleian Géométrie 3D We live in a three-dimensional world. Every object you can see or touch has three dimensions that can be measured: length, width, and height. The room you are sitting in can be described by these three dimensions. In the world around us, there are many three-dimensional geometric shapes.
about Hey there. My name is Maria Popova and I’m a reader, writer, interestingness hunter-gatherer, and curious mind at large. I’ve previously written for Wired UK, The Atlantic, The New York Times, and Harvard’s Nieman Journalism Lab, among others, and am an MIT Futures of Entertainment Fellow. Maria Popova. Brain Pickings is my one-woman labor of love — a subjective lens on what matters in the world and why. Founded in 2006 as a weekly email that went out to seven friends and eventually brought online, the site was included in the Library of Congress permanent web archive in 2012. Here’s a little bit about my seven most important learnings from the journey so far. I think of it as LEGOs — if the bricks we have are of only one shape, size, and color, we can build things, but there’s a limit to how imaginative and interesting they will be. Please enjoy. For more on the ethos behind this labor of love, here is my On Being conversation with the wonderful and generous Krista Tippett:

7 Strategies To Help Students Ask Great Questions Bring TeachThought Professional Development To Your School! 7 Strategies To Help Students Ask Great Questions by Terry Heick Questions can be extraordinary learning tools. A good question can open minds, shift paradigms, and force the uncomfortable but transformational cognitive dissonance that can help create thinkers. The latter is a topic for another day, but the former is why we’re here. 8 Strategies To Help Students Ask Great Questions 1. The TeachThought Learning Taxonomy is a template for critical thinking that frames cognition across six categories. It imagines any learning product, goal, or objective as a “thing,” then suggests different ways to think about said “thing”–mitosis, a math formula, an historical figure, a poem, a poet, a computer coding language, a political concept, a literary device, etc. 1. 2. 3. 4. 5. 6. A literary device–a metaphor example, is usually studied in isolation. Self--Identity what you do and don’t understand about the metaphor The upside? 2. 3. 4. 5. 6.
The Hermitage How to lose weight (in the browser) And what if we got together a bunch of experts who work on large sites to create a definitive front-end performance guide? And not just one of those boring guides made for robots, what if we did something fun? What about getting together Briza Bueno (Americanas.com), Davidson Fellipe (Globo.com), Giovanni Keppelen (ex-Peixe Urbano), Jaydson Gomes (Terra), Marcel Duran (Twitter), Mike Taylor (Opera), Renato Mangini (Google), and Sérgio Lopes (Caelum) to make the best reference possible? That's exactly what we've done! And we'll guide you in this battle to create even faster sites. — Zeno Rocha, project lead. Of course it matters and you know it.

A Map of Learning Theory Concepts, Theorists, Paradigms and Disciplines Learning theory is complex, and while the graphic below may initially seem to reinforce that idea, it actually makes a complicated topic very digestible. Richard Millwood is an assistant professor at Trinity College Dublin, and he also runs Core Education, a nonprofit that helps schools use technology for better learning outcomes. As part of his work for the HoTEL Project (Holistic Approach to Technology Enhanced Learning), Millwood created this guide to learning theories. On his blog, Millwood describes his motivation to collect information and resources about learning theories featured in the map: Learning theory has been a contested scientific field for most of its history, with conflicting contributions from many scientific disciplines, practice and policy positions.

The Difference Between Being In Love And Just Being Attached Is it love, or is it just attachment? We all have those friends who jump from relationship to relationship, and each time, they are “totally and completely in love.” For those of us who have been single longer than two of their relationships combined, we can't help but wonder how someone can possibly be “in love” with all these people. I mean, come on. Yes. But what if your feeling is wrong? You know those relationships you got out of, and after a few months, you couldn't believe you ever said those three beautiful words to someone you wouldn't want to be seen with today? Well, it's usually because it wasn't love. I have no real insight in knowing if your love is real or if it's just insecurity masked in AXE body spray, but I can give you some general pointers. Because you don't want to attend a wedding where the only thing the bride has to say about the groom is that “he's always there.” Love is passionate; attachment is apathetic Love is selfless; attachment is self-centered
