A burst of colour on a monochromatic panorama, a field of flowering quinoa plants in the Bolivian desert is a thing of beauty. A plant ready for harvest can stand higher than a human, covered with knotty blossoms, from violet to crimson and ochre-orange to yellow.
Quinua real, or royal quinoa, flourishes in the most hostile conditions, surviving nightly frosts and daytime temperatures upwards of 40C (104F). It is a high-altitude plant, growing at 3,600 metres above sea level and higher, where oxygen is thin, water is scarce and the soil is so saline that virtually nothing else grows.
The tiny seeds of the quinoa plant are the stuff of nutritionists' dreams, sending demand soaring in the developed world. Gram-for-gram, quinoa is one of the planet's most nutritious foodstuffs. Once a sacred crop for some pre-hispanic Andean cultures, it has become a five-star health food for the middle classes in Europe, the US and increasingly China and Japan.
That global demand means less quinoa is being eaten in Bolivia and Peru, the countries of origin, as the price has tripled. There are concerns this could cause malnutrition as producers, who have long relied on the superfood to supplement their meagre diets, would rather sell their entire crop than eat it. The rocketing international price is also creating land disputes.John Singer Sargent
(1856 - 1925) was an American artist, considered the
"leading portrait painter of his generation" for his
evocations of Edwardian era luxury. During his career, he
created roughly 900 oil paintings and more than 2,000
watercolors, as well as countless sketches and charcoal
drawings.

Golden rectangle
A golden rectangle
is a rectangle whose side lengths are in the golden ratio,
one-to-phi, that is, approximately 1:1.618. A distinctive
feature of this shape is that when a square section is
removed, the remainder is another golden rectangle, that is,
with the same proportions as the first. Square removal can
be repeated infinitely, which leads to an approximation of
the golden or Fibonacci spiral.
Droste Effect
The Droste effect is a specific kind of recursive picture, one that in heraldry is termed mise en abyme. An image exhibiting the Droste effect depicts a smaller version of itself in a place where a similar picture would realistically be expected to appear. This smaller version then depicts an even smaller version of itself in the same place, and so on. Only in theory could this go on forever; practically, it continues only as long as the resolution of the picture allows, which is relatively short, since each iteration geometrically reduces the picture's size. It is a visual example of a strange loop, a self-referential system of instancing which is the cornerstone of fractal geometry.
