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?

Stunning Hope Cottage Includes A 2-Person Sauna - Tiny House for UsTiny House for Us Just when you think you’ve found your favorite tiny house design, something like this comes along and raises the bar another notch. It’s great to see what others are doing with small space design, and this might be the first time we’ve seen a full-blown sauna built into a tiny home. Described as a sort of “glamping bed and breakfast”, the Hope Cottage is located in La Conner, Washington, and was built to offer visitors a cozy place to escape it all. They managed to include all the normal luxuries you’d expect in a home; there’s a usable kitchen space, comfortable living area, roomy sleeping loft, and a full bathroom with shower, toilet, and of course a gorgeous FAR infrared sauna enclosed in glass and wood. As if the sauna weren’t enough, they managed to fit a shower in the bathroom too! They opted for stairs to the loft, making it more accessible for people of all ages and abilities. The Hope Cottage in its natural evergreen setting, with a garden shed right behind it.

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.

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:
Les cartes de pays imaginaires - Voyage dans les contrées de l'utopie «Souvent, l’objet du désir, où le désir se transforme en espoir, devient plus réel que la réalité elle-même. » Célèbre romancier italien, mais aussi philosophe, essayiste, critique littéraire, Umberto Eco a longtemps été fasciné par le symbolique et le métaphorique, qu’on retrouve par exemple dans ses livres pour enfants (les trois cosmonautes, la bombe du général,…). Il revisite aujourd’hui ces allégories qui lui sont chères dans « Le Livre des terres légendaires »; un voyage illustré dans les plus grands lieux imaginaires de l’histoire, peuplés d’habitants fantaisistes et coutumes étranges, qui prennent place dans des lieux aussi différents que la mythique Atlantide ou le petit appartement de Sherlock Holmes. On peut également y découvrir le royaume de la Reine de Saba, celui du prêtre Jean, des îles de Gulliver, l’Eldorado et le Pays de Cocagne,… Eco écrit dans l’introduction : La réalité de ces illusions est le sujet de ce livre ».

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.
Wakako Kawakami’s Striking Installations of Giant Textile Birds When Alfred Hitchcock directed his classic film The Birds, he left open the question as to why the birds turned their fixation towards humanity. The mystery surrounding his film made it one his most chilling pieces of work, portraying a bird’s-eye view of the world as if nature were judging us. Osaka based Japanese artist Wakako Kawakami takes a note from Hitchcock with her giant textile budgies that she installs in various locations.
