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?

The Best Tools for Visualization Visualization is a technique to graphically represent sets of data. When data is large or abstract, visualization can help make the data easier to read or understand. There are visualization tools for search, music, networks, online communities, and almost anything else you can think of. Whether you want a desktop application or a web-based tool, there are many specific tools are available on the web that let you visualize all kinds of data. Here are some of the best: Visualize Social Networks Last.Forward: Thanks to's new widget gallery, you can now explore a wide selection of extras to extend your experience.

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.
