In the past few years, a few things have happened. One is that we’ve learned that the number 11, like the years, is a symbol. It is often used to express the importance of a certain concept, such as a person’s life. Another thing is that we’ve learned that there are many types of elevens, which we can learn about.

St. Ursula

St Ursula is a famous saint from Europe who was a martyr during the Hun invasion of the fourth century. Her name is also commonly associated with the Order of Ursulines, a religious order that promotes the education of girls and young women. The cult of Saint Ursula and the Eleven Thousand Virgin Martyrs of Cologne is one of the most prominent relic cults in medieval Europe.

St Ursula’s story is a tragic one that has been interpreted in many ways. She is often pictured with a crown and a banner. One legend describes her as being beautiful and exceptionally virtuous. Another version claims she was a princess. However, these stories are not supported by history.

One of the earliest known versions of the Ursula story originated from the Cologne area. This is one of the few ancient versions of the story that does not mention Ursula as the main leader. Its origins are obscure, but it is believed to have been written around the second half of the ninth century.

While the legend has been widely circulated throughout the Middle Ages, it was not until the thirteenth century that a work based on it was compiled. Jacobus de Voragine compiled Legenda aurea in 1228-1298.

Another version was compiled in the tenth century. In this version, the phrase “11,000 virgins” appears for the first time. Various scholars and writers compiled martyrologies for the Virgins of Cologne. These included Usuard and Wandalbert of Prum.

Several thousand of the saints and virgins at Cologne were martyred, but the number of the actual martyrs is unknown. During the Dark Ages, the amount of historical documentation for events and people in Europe was very low.

Apollo 11

Apollo 11 made history as the first humans to walk on the Moon. Astronauts Neil Armstrong and Buzz Aldrin walked on the surface for two hours and thirty-one minutes. They collected 50 pounds of lunar samples, and spent a total of twenty-one and a half hours on the Moon.

After landing, the astronauts were transferred to the 58-room Lunar Receiving Laboratory. They then donned protective spacesuits. The crew was checked for diseases, and rubbed down with iodine.

NASA took safety seriously, and kept the astronauts in touch with Mission Control in Houston. This was done using the Unified S-Band Transponder, which transmitted all voice and video communications.

There were three main goals of the Apollo 11 mission: to land humans on the moon, return them safely to Earth, and collect materials for future human landings on the Moon. The astronauts also deployed a laser retroreflector to help with precise measurements.

In addition to the lunar landing, the mission included extensive photography of the Moon’s terrain and deployment of a seismic experiment package. It was also the last mission to fly the “free-return” trajectory.

During the initial lunar orbit, Armstrong and Aldrin used the laser retroreflector to measure lunar quakes, and they installed a seismometer. As for the moonwalk, they measured the distance between the Moon and the Earth, and they installed a solar wind composition device.

Aside from the moonwalk, the Apollo 11 astronauts also did extensive photographic work of the lunar surface, and deployed a television camera. Their televised image was viewed by an estimated 500 million people.

However, the biggest achievement of the Apollo 11 mission was the return to Earth. The astronauts were safe and well, and they returned to their launch vehicle.

Eleven-sided polygons

Most schools will no doubt be snazzed by the flurry of newbies and old hands. It’s a good idea to provide a little pixie dust to get them out of the door. The best way to do this is to set up a multi-person contest. This will ensure the prize pool isn’t all too narrowly focused on one or two students. If you’re lucky you might even wrangle up a sextet.

While the classroom is a veritable smorgasbord, the lab can be a little more exclusive. For the most part, I’m a fan of the tried and true. A couple of grad students can do the heavy lifting. Alternatively, one or two students can play the sexer sextet role while the rest slumber. Luckily, there’s no shortage of cool grad students at the school. In fact, a few students might actually be the stars of the class. This is the perfect opportunity to test out the best and worst of breed. Moreover, grad students can pick and choose from a variety of elective courses based on their needs and interests.

Eleven-sided uniform tilings in two-dimensional Euclidean space

Eleven-sided uniform tilings are tilings of the space in Euclidean geometry. Eight are semiregular tilings, and one is regular. This group of tilings is part of a larger class of aperiodic tilings.

These tilings are generated by a substitution system that involves the use of similar triangles. These tilings have paths that are a nearly perfect match for the Euclidean straight-line distance.

A truncated octahedron is an optimal solution to the Kelvin conjecture. It was discovered by Phelan and Weaire. They also discovered a better method for partitioning the space.

A square pyramid is not a good solution to the Kelvin conjecture. The worst angle that can be made by a triangle on an integer lattice is 30 degrees.

Several researchers have investigated combinatorics of periodic tilings. Daniel Huson has worked on the combinatorics of periodic tilings in two and three dimensions. He has written a number of papers.

Thomas Banchoff has investigated the intersections of perspective triangles, tetrahedra, and spheres. His results relate to Desargues’ theorem and Monge’s theorem. In particular, his results generalize to higher dimensional spheres.

Another researcher has developed an interactive tool for visualizing hyperbolic tilings. Martin Erren has a graphical applet. Other software includes Kaleidotile, which visualizes tilings of the sphere.

One of the most famous problems in geometry is the Kakeya-Besicovitch problem. It is a challenge to rotate a needle in a minimal area.

The Geometry Center has a collection of interactive on-line geometry. Some of the objects include Riemann surfaces, Escheresque tessellations, and Penrose tilings. There are also links to Escher’s periodic drawings.

There is also a section on perecquian configurations. These are shapes that are invariant under rotation, translation, and reflection.
