So we finally solved the to-go coffee cup problem - a lid with a flap that NOW LOCKS IN BOTH DIRECTIONS! Solving our dependency on fossil fuels must be right around the corner! (of course, petroleum products are likely used in making that there lid)
In the current exhibit of Rembrandt's drawings, the museum provides magnifying glasses so you can inspect the detail and block everyone else looking at the picture. I wasn't actually allowed to take this photo of the traveling piece, but, you know, it's cute.
This one is actually by one of Rembrandt's students, whose work was not allowed to be signed and was usually attributed to the master. Poor 17th-century chumps.
What is a linear equations solver: An equation is a condition on a variable. A variable takes on different values; its value is not fixed . Variables are denoted usually by letter of alphabets, such as x, y , z , l , m , n , p etc. From variables we form expression. Linear equation in one variable : These are the type of equation which have unique (i.e, only one and one ) solution. For example: 2 x + 5 = 0 is a linear equation in one variable.
Juvenile bird (note yellow cere).
Kea – Nestor notabilis (family Strigopidae)
A protected rare species of alpine parrot endemic to New Zealand.
Found in forested and alpine regions of the South Island.
Little is known about their population except that it seems to be in decline (c. 5000 birds).
The Kea was once killed for bounty as it occasionally preyed on livestock, especially sheep. It is now known that only a few kea learn this trick and most kea seen on dead sheep are scavanging an already dead carcass.
It only received full protection in 1986.
Kea nest in burrows or crevices among the roots of trees. They are regarded as one of the most intelligent birds in the world, and for their insatiable curiosity, both vital to their survival in a harsh mountain environment. Kea can solve logical puzzles, such as pushing and pulling things in a certain order to get to food, and will work together to achieve a certain objective.
The Kea is a large parrot about 48 cm (19 in) long and weighing about 1 kg (2.2 lb). It has mostly olive-green plumage with a grey beak having a long narrow curved upper beak. The adult has dark-brown irises, and the cere, eyerings, and legs are grey. It has orange feathers on the undersides of its wings. The feathers on the sides of its face are dark olive-brown, feathers on its back and rump are orange-red, and some of the outer wing feathers are dull-blue. It has a short and broad bluish-green tail with a black tip. Feather shafts project at the tip of the tail and the undersides of the inner tail feathers have yellow-orange transverse stripes. The male is about 5% longer than the female, and the male's upper beak is 12–14% longer than the female's. Juveniles generally resemble adults, but have yellow eyerings and cere, an orange-yellow lower beak, and grey-yellow legs. Kea range from lowland river valleys and coastal forests of the westcoast up to the alpine regions of the South Island such as Arthur's Pass and Aoraki/Mount Cook National Park, closely associated throughout its range with the southern beech (Nothofagus) forests in the alpine ridge. Apart from occasional vagrants, Kea are not found in the North Island, although fossil evidence suggests a population lived there over 10,000 years ago. The population was estimated at between 1,000 and 5,000 individuals in 1986, contrasting with another estimate of 15,000 birds in 1992. Both estimates depend heavily upon the assumptions made. The Kea's widespread distribution at low density across inaccessible areas prevents accurate estimates. Their notorious urge to explore and manipulate, combined with strong attraction to anything new or different in their environment makes this bird a pest for residents and an attraction for tourists. Called "the clown of the mountains", it will investigate backpacks, boots or even cars, often causing damage or flying off with smaller items. People commonly encounter wild Kea at South Island ski areas. The Kea are attracted by the prospect of food scraps. Their curiosity leads them to peck and carry away unguarded items of clothing or to pry apart rubber parts of cars—to the entertainment and annoyance of human observers. They are often described as "cheeky". A Kea has even been reported to have made off with a Scottish man's passport while he was visiting Fiordland, and theft of car keys, leaving tourists stranded, is a story that has passed into legend.
Mortality is high among young Kea, with less than 40% surviving their first year. The median lifespan of a wild subadult Kea has been estimated at 5 years, based on the proportion of Kea seen again in successive seasons in Arthur's Pass, and allowing for some emigration to surrounding areas. Around 10% of the local Kea population were expected to be over 20 years of age. The oldest known captive Kea was 50 years old in 2008. At least one observer has reported that the Kea is polygynous, with one male attached to multiple females. The same source noted that there was a surplus of females. Kea are social and live in groups of up to 13 birds. Isolated individuals do badly in captivity but respond well to mirror images. In one study, nest sites occur at a density of 1 per 4.4 km². The breeding areas are most commonly in Southern Beech (Nothofagus) forests, located on steep mountain sides. Breeding at heights of 1600 m above sea level and higher, it is one of the few parrot species in the world to regularly spend time above tree line. Nest sites are usually positioned on the ground underneath large beech trees, in rock crevices or dug burrows between roots. They are accessed by tunnels leading back 1 m to 6 m into a larger chamber, which is furnished with lichens, moss, ferns and rotting wood. The laying period starts in July and reaches into January. Two to five white eggs are laid, with an incubation time of around 21 days, and a brooding period of 94 days. An omnivore, the Kea feeds on more than 40 plant species beetle larva, other birds (including shearwater chicks) and mammals (including sheep and rabbits). It has been observed breaking open shearwater nests to feed on the chicks after hearing the chicks in their nests. The Kea is classed as Nationally Endangered in the New Zealand Threat Classification System and Vulnerable in the IUCN Red List.
An equations is a combination of one or more terms separated with equal symbol "=". Terms can be numerical, alphanumerical, expression etc. Different type of equations.How to Solve Equations : In these types of equation we can find the value of variable like a, b, c.

This colourful new view shows the star-forming region LHA 120-N44 [1] in the Large Magellanic Cloud, a small satellite galaxy of the Milky Way. This picture combines the view in visible light from the MPG/ESO 2.2-metre telescope at ESO’s La Silla Observatory in Chile with images in infrared light and X-rays from orbiting satellite observatories. At the centre of this very rich region of gas, dust and young stars lies the star cluster NGC 1929. Its massive stars produce intense radiation, expel matter at high speeds as stellar winds, and race through their short but brilliant lives to explode as supernovae. The winds and supernova shock waves have carved out a huge cavity, called a superbubble, in the surrounding gas. Observations with NASA's Chandra X-ray Observatory (shown here in blue) reveal hot regions created by these winds and shocks, while infrared data from NASA's Spitzer Space Telescope (shown in red) outline where the dust and cooler gas are found. The visible-light view from the MPG/ESO 2.2-metre telescope (in yellow) completes the picture and shows the hot young stars themselves as well as the glowing clouds of gas and dust that surround them. Combining these different views of this dramatic region has allowed astronomers to solve a mystery: why are N44, and similar superbubbles, giving off such strong X-rays? The answer seems to be that there are two extra sources of bright X-ray emission: supernova shock waves striking the walls of the cavities, and hot material evaporating from the cavity walls. This X-ray emission from the edge of the superbubble shows up clearly in the picture. Links NASA’s Chandra X-ray Observatory NASA’s Spitzer Space Telescope Notes [1] The designation of this object indicates that it was included in the Catalogue of H-alpha emission stars and nebulae in the Magellanic Clouds, compiled and published in 1956 by American astronomer–astronaut Karl Henize (1926–1993). The letter “N” indicates that it is a nebula. The object is often called simply N44.
A number which satisfies the given equation is called a solution or root of that. ‘solve equations online’ means that if the variable (literal) involved in this is replaced by the number, then both sides of that become equal. The process of finding the particular value of the variable (literal) which makes both sides of the equation equal is called solving the equation. Below are rules that need to be followed in solving equations.

Hope this is more difficult than the last one. It's really white, I just decided not to color correct it...
Day 1 Clue: Most of these have a handle, but this one doesn't.
Day 2 Clue: Usually these are used outdoors, but this one works indoors or out.
Opening night. About Chicago street artist Brendan Scanlon/SOLVE, murdered in 2008 at the age of 24. It was good to see this show was totally packed in zero degree weather. (Oh, and I met two of my Flickr contacts for the first time.)
