Eleven is a number which is used to count numbers, and it has been used in various mathematical contexts. For example, we can count the players on an association football team, or we can count the number of sides of a polygon. We can even use eleven to measure a tiling of a two-dimensional Euclidean space.

St. Ursula

The legend of St. Ursula has intrigued the world for centuries. It is a mythical tale about a British princess, who was betrothed to a pagan prince. She decided to go on a holy pilgrimage to Rome before marriage.

Ursula, along with her travel companions, were massacred by the Huns in Cologne. According to the legend, the Huns were a nomadic race from Central Asia. They conquered much of Europe in the fourth century.

Saint Ursula was raised by God to protect women. Her mission was to spread her message of love and faith among women. Before her death, she announced that she was on a pan-European pilgrimage.

In the ninth century, a sermon, titled Passio Ursulae, was written. It explains the history of Ursula. Several thousand virgins were also martyred in Cologne. Some were virgin handmaids of the royal entourage.

Other texts mention eleven virgins. These include five virgins of Cologne. Nevertheless, no account mentions all 11,000.

The 11th-century burial was identified as that of Ursula and her companions. A number of the skeletons were found to be of small children.

However, the story of Ursula and her companions has received a wide range of explanations. The chief is an error of interpretation.

Another possible explanation is that the Huns were not the source of the story. Instead, it is more likely that the story is based on an earlier version.

Various scholars, including Sirmond and Leibniz, have given their own version of the story. According to these, Ursula was a daughter of the Romano-British king Dionotus. One version also states that she was the sister of the Christian king of Great Britain.

Eleven-sided polygons

When was the last time you actually took a close look at an 11 sided polygon? In this classy context, it’s a good idea to take a gander at some of the aforementioned eminently polygonal slurs before stepping up to the keyboard. A quick search on your smartphone should do the trick. This activity is bound to wrack up some enlightened sprites. The next challenge is figuring out which of them are tethered. Luckily, there is a plethora of apps that can help you get to that next level. That’s not to mention that you’ll find a handful of knuckleheads with whom you can hang out over a few glasses of booze. For the more tech savvy sexes, you can even set up your own virtual office. You don’t have to break the bank to do it, either.

With the right tools in hand and a little luck, you’ll have a solid smorgasboard to boot. If you’re looking to dabble in the edusphere, you’re sure to find some interesting tidbits among the edifices abound. Make sure you take a peek at this page before tackling your next assignment. As the last item on your to-do list, you’ll be happy you did.

Messier object M11

M11 is a large, bright open cluster in the constellation Scutum. It is the most densely populated open cluster in the Messier catalog. There are approximately 2900 stars in the cluster. This makes it one of the most abundant star clusters in the universe.

Despite the density, M11 is actually only about 14 arcminutes across. As a result, it is easy to find with binoculars. Moreover, it is an ideal target for small telescopes. With a moderate power telescope, you can even frame M11 within the Milky Way.

While M11 is relatively youthful, it contains several red giants. The total luminosity of the cluster is over ten thousand times that of the Sun. In addition, it contains a significant number of yellow giants.

M11 also has a number of variable stars. One of these is the RV Tauri type, which varies in brightness from magnitude 4.8 to 9. Also, many of the variable stars are eclipsing binary stars.

M11 is located in the Scutum Star Cloud, a large star cloud in the Scutum constellation. This cloud is the brightest part of the Milky Way, outside of Sagittarius.

In fact, the size of the Scutum star cloud is so great that M11 appears to be a globular cluster. Although the cluster is only one quarter of a degree wide, it contains eight hundred stars.

M11 is best viewed during dark, moonless nights in May and August. Although it can be seen with the naked eye, it will be hard to get a good view without a pair of binoculars.

As for the name, M11 is a reference to the V-shaped formation of stars in the cluster. Its center is a bright point of light. It is about 6,000 light-years from Earth and is only 14 arcminutes in diameter.

Eleven-sided convex uniform tilings in two-dimensional Euclidean space

A group of eleven convex uniform tilings exists in the Euclidean plane. They include trihexagonal tiling, which is part of the triangular-hemiapeirogonal tiling. The vertex of a trihexagon is a point that intersects two bordering tiles.

Other known tilings in the plane include square, octagon, hexagon, and polygon. These tilings can be divided into seven frieze groups. For example, square tiling has four squares at every vertex. However, it can also be defined as a tiling with a single prototile.

In addition to the above tilings, there are several tilings that use irregular pentagons. One of these is the Hirschhorn tiling. It was published in 1985 by Michael D. Hirschhorn and D. C. Hunt.

Another is the Delaunay triangulation. Using the Delaunay triangulation, a line can be triangulated to form a square or a hexagon. When used in conjunction with the Conway criterion, this criterion is sufficient to tile the plane.

Anisohedral tiling is a special case of monohedral tiling. To form an anisohedral tiling, the transitivity class must be the same. This classification has been difficult for a number of years, but it is now completed.

In addition to these uniform tilings, there are 14 nonconvex uniform tilings in the plane. These are described by the vertex configuration. Some of these are known as star polygons, and others by reverse orientation vertex configurations.

There are also a number of other tilings that use regular polygons. Many of these tiles are useful for puzzles and games.

The tilings can be extended to other spaces. For example, tessellations of non-Euclidean spaces are often used in quilting and Islamic art. Escher was an artist who also frequently used tessellations. He used them in his famous pavements.

Eleven players on an association football team

One of the oldest sports to be formalised in the sandbox is football or soccer as the Brits like to call it. Some cite it as the predecessor to cricket. The earliest precursors to the modern game may have been the Aztecs. As the sport matured and evolved into what it is today, its various incarnations have branched out into international competitions.

Football is played on a rectangular field called the pitch. It is roughly 120 yards long and has a diameter of about 18 yards. The most notable thing about the pitch is that it must be mirror image. It also has to have a goalpost at each end.

A typical game consists of two 45-minute halves followed by a 15-minute half. Matches involving two or more teams usually end in a draw. The match may go to extra time if the scores are tied. On average, a football game lasts about 90 minutes.

The most popular of the association football leagues is the English Premier League. There are about 200 professional clubs, most of whom play in the top flight. Although the competition is fierce, a high standard of play is maintained.

One of the major reasons for this is the amount of money clubs are willing to spend on kit. This is especially true in England where kit costs can run into the millions of pounds. In some cases, it is worth the extra money to win the title of best team in the country. Even if a club does not qualify for the top flight, the rewards are well worth the effort.

Eleven players is the optimum number of players for various roles on the pitch.
