Louis Antoine
Louis Antoine (23 November 1888 – 8 February 1971) was a French mathematician who discovered Antoine's necklace, which J. W. Alexander used to construct Antoine's horned sphere. He lost his eyesight in the first World War, at the age of 29. Early life Louis Antoine was born in Mirecourt. He studied at the lycee in Nancy. His father was a director of a manufacturer of matchsticks. After this, he studied at the Collège de Compiègne.

Antoine's Necklace
In mathematics, Antoine's necklace is a topological embedding of the Cantor set in 3-dimensional Euclidean space, whose complement is not simply connected. It also serves as a counterexample to the claim that all Cantor spaces are ambiently homeomorphic to each other. It was discovered by . Construction Antoine's necklace is constructed iteratively like so: Begin with a solid torus ''A''0 (iteration 0). Next, construct a "necklace" of smaller, linked tori that lie inside ''A''0. This necklace is ''A''1 (iteration 1). Each torus composing ''A''1 can be replaced with another smaller necklace as was done for ''A''0. Doing this yields ''A''2 (iteration 2). This process can be repeated a countably infinite number of times to create an ''A''''n'' for all ''n''. Antoine's necklace ''A'' is defined as the intersection of all the iterations. Properties Since the solid tori are chosen to become arbitrarily small as the iteration number increases, the connected components of ''A'' must ...

People From Mirecourt
The term "the people" refers to the public or common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independent sovereignty and therefore secession. Indeed, judge Ivor Jennings identified the inherent problems in the right of "peoples" to self-determination, as i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Braille
Braille ( , ) is a Tactile alphabet, tactile writing system used by blindness, blind or visually impaired people. It can be read either on embossed paper or by using refreshable braille displays that connect to computers and smartphone devices. Braille can be written using a slate and stylus, a braille writer, an electronic braille notetaker or with the use of a computer connected to a braille embosser. For blind readers, braille is an independent writing system, rather than a code of printed orthography. Braille is named after its creator, Louis Braille, a Frenchman who lost his sight as a result of a childhood accident. In 1824, at the age of fifteen, he developed the braille code based on the French alphabet as an improvement on night writing. He published his system, which subsequently included musical notation, in 1829. The second revision, published in 1837, was the first Binary numeral system, binary form of writing developed in the modern era. Braille characters are f ...
