Geek fun: Twisted Architecture. I didn’t set out to tie knots in Norman Foster’s Hearst Tower or wrinkle his Gherkin, but I got carried away. It’s one of the occupational hazards of working with Mathematica. It started with an innocent experiment in lofting, a technique also known as “skinning” that originated in boat-building. I wanted to explore some three-dimensional forms, and a basic lofting function seemed like a quick ticket to results. I dashed off the function Loft, which takes a stack of three-dimensional contours and covers it with a skin of polygons. Loft uses Mathematica‘s GraphicsComplex primitive to factor out the geometries of the polygons from their topologies.
The contour point coordinates are collected in the first argument. I tried out Loft by embedding it in a Manipulate, and was happily on my way discovering some interesting new forms. Even this trivial parameterization of a scaled and twisted half-sphere yields an amazing variety of forms, each of which suggests interesting avenues to explore.

Mathematica Solution for Financial Risk Management. Financial Data on Demand: Building an Interactive Web Service with Mathematica. Blog : The Ongoing Stock Market Crash. The ongoing gyrations of the stock market over the past few months have spread panic not just throughout the markets, but into the rest of the economy and the political sphere. There are some who assert that this is due to the recent downgrade of the American credit rating by Standard & Poor’s (S&P), but an analysis with Mathematica suggests that other factors may be at play. Using the FinancialBond function for a zero-coupon continuously compounding bond price, we discover the inverse relation between bond prices and yields (y) given below. As the bond price increases, the yield y decreases. As bonds are bought, their prices go up and the corresponding yields drop. Instead, it may have been the news about the redetermination of the size of the 2008–2009 decline in GDP from 4.8% to 8.9% that caused the panic, or recent evidence that the economy has stalled and might possibly decline in the second half of the year.
However, what these charts do not reveal is the extent of the downturn. Diet. HomeDecor. The principle is simple and seductively clever: solar lights that store energy during the day and release light at night. These can be purchased ready-made in a variety of colors (yellow, blue and red) but they can also be built at home.
A simple, less-technical approach involves buying a conventional solar-powered yard lamp and then essentially harvesting it for key pieces to put in a jar. This is simply a way of taking an existing solar lamp design and appropriating its parts to make something more attractive for display around a house or home. A more electronically-savvy individual can take the more complex route and built a solar lamp from the ground up using small solar panels – though the aesthetic result may not be as impressive. Whatever route you choose to go, these are fun and sustainable gadgets that make it easy to go green, automate the process of turning on lights at night and can add some color to your porch, patio, garden or windowsill.

Patrick selected "a range of species from the world's main temperate zones, essentially from the northern hemisphere (North America, Europe, the Himalayas, China, Japan). A few of the species were collected in Korea and Japan, such as Elastostema umbellatum, Pilea petiolaris, and Ixeris stonlonifera. I also incorporated a few species from the southern hemisphere's temperate zones, such as Berberis darwinii and B. linearifolia from Chile and Phygelius capensis from South Africa. "It was obviously impossible to include tropical species in the Paris outdoors, on a façade with northern exposure swept by air currents from the Seine.
Yet I insisted that the biodiversity represented in this vertical garden echo the cultural diversity of artists the world over, whose works were on exhibit in that very museum," (The Vertical Garden, 2008). Vertical Gardening. Vertical Gardening:The Key to a Lack of Floor Area Vertical gardening is another branch of the many faces of vegetable container gardening. The vertical vegetable garden layout is a particularly good idea if you do not have a large footprint area on the ground where you can grow things. Growing Upwards! Vertical growing is particularly suited to climbing plants such as runner beans, French beans, peas, squash, cucumbers and courgettes, melons and even marrows.
This can be done in many ways depending on the plants being grown. Another common and easy method of vertical growing for things like beans is to make a kind-of wigwam shape with bamboo sticks stuck into the container, and tied at the top. Ready-constructed tomato cages or spirals are a good example of the type of supports that are readily available on the market for your tomato plants. The structure can be moved to a position above the pots so they can all climb onto it from both sides. Use Your Airspace! No dig gardens.
