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.
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.
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 ».

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.
The Hermitage Sacred Tree Profile: Hawthorn (Lore, medicine, magic, and mystery) Hawthorn branches and leaves In honor of Samhuinn, a festival of beginnings and endings, today we’ll explore the most sacred of trees–the hawthorn. This is the 6th post in my “Sacred Trees in the Americas” series where I examine abundant trees in the Eastern and Midwestern parts of the USA, exploring their many qualities: physical, magical, herbal, mythological, and so on. Previous posts have include Eastern Hemlock, American Beech, Sugar Maple, Eastern White Cedar, and Hickory. There are few trees quite so enigmatic in either western herbalism practice or contemporary druidry as the sacred hawthorn—and this is the first of the sacred trees of the Americas series that is included in the traditional Ogham, although I want to add to our knowledge of this tree. I remember when I was a child, running through the hawthorn grove behind my house. As an adult, I would be thrilled to come across a hawthorn in full fruit, ready and waiting for a harvest.

Le Divan Fumoir Bohémien How Does Ethnicity Influence Game Design? - remeshed.com remeshed.com Catt Small, of the Brooklyn Gamery and Code Liberation Foundation, and Asia Hoe, working on their five stages of grief action game at Global Game Jam 2014 “My ethnicity affects every aspect of my life, the same as it does for everyone. How I view the world, how I communicate, how I feel and think. Over our recent series of articles on women of color in game development, we’ve spoken with game developers from many different backgrounds about their games, accomplishments and advice for up-and-coming game developers. One aspect of the conversations that stood out was the discussion of ethnicity, and how it affected the game developer, and game design. I spoke with twelve developers: five Black women, four Latin/Hispanic women, two Asian women, and one Native American woman. And isolation affects their career. “The first time I had the opportunity to write code with another black woman was twelve years into my career,” said Angie Jones, developer of Diva Chix. “I don’t see them.

Make Your Own Wood-Fired Hot Tub Fancy having a hot tub? I’m sure many would, but the expense of buying and running one is just out of the question, especially if you’re trying to stay off the grid. Well here we have the answer – a wood fired hot tub that you should fit in perfectly with your homestead. This fantastic DIY guide was put together by Skiing Magazine and was featured in their February / March 2009 issue. It’s not the easiest job, but building your own wood-fired hot tub can save you thousands of dollars if you’re willing to dig a hole and learn some basic concrete skills. Line the pit with plastic sheeting, using roofing nails to tack it into the dirt. Get a professional to help you estimate how much concrete you’ll need. Buy a submergible stove for around $750 and place it in the narrow part of the keyhole pit. You’ll need a way to drain the tub. Make an insulating cover out of two-inch closed-cell foam to hold in heat. via MidlyInteresting Now check out this DIY 2 week hot tub project: Recent articles
