On September 14, 2015, 14-year-old Ahmed Mohamed was arrested at MacArthur High School in Irving, Texas, for bringing a disassembled digital clock to school. The incident ignited allegations of racial profiling and Islamophobia from many media sources and commentators.

The episode arose when Mohamed reassembled the parts of a digital clock in an 8-inch (20 cm) pencil container and brought it to school to show his teachers. His English teacher thought the device resembled a bomb, confiscated it, and reported him to the principal. The local police were called, and they questioned him for an hour and a half. He was handcuffed, taken into custody and transported to a juvenile detention facility, where he was fingerprinted and his mug shot was taken. He was then released to his parents. According to local police, they arrested him because they initially suspected he may have purposely caused a bomb scare. The case was not pursued further by the juvenile justice authorities, but he was suspended from school.

Following the incident, the police determined Mohamed had no malicious intent, and he was not charged with any crime. News of the incident went viral – initially on Twitter – with allegations by commentators that the actions of the school officials and police were due to their stereotyping of Mohamed based on his Sudanese ancestry and Muslim faith. Afterwards, U.S. President Barack Obama as well as other politicians, activists, technology company executives, and media personalities commented about the incident. Many of them praised Mohamed for his ingenuity and creativity, and he was invited to participate in a number of high-profile events related to encouraging youth interest in science and technology. Although Mohamed was cleared in the final police investigation, he became the subject of conspiracy theories – many of them contradictory, citing no evidence, and conflicting with established facts – which claimed that the incident was a deliberate hoax.

On November 23, 2015, Ahmed's family threatened to sue the City of Irving and the school district for civil rights violations and physical and mental anguish unless they received written apologies and compensation of $15 million. This lawsuit was dismissed in May 2017 for lack of evidence. The family also sued conservative talk show hosts Glenn Beck, Ben Shapiro, and another Fox News commentator for lesser amounts on the grounds of defamation of character. Both cases were dismissed with prejudice for First Amendment free speech reasons. In late 2015, his family decided to accept a scholarship from the Qatar Foundation and move to Qatar.

Epiousios (ἐπιούσιος) is a Greek adjective used in the Lord's Prayer verse "Τὸν ἄρτον ἡμῶν τὸν ἐπιούσιον δὸς ἡμῖν σήμερον" 'Give us today our epiousion bread'. Because the word is used nowhere else, its meaning is unclear. It is traditionally translated as "daily", but most modern scholars reject that interpretation.

Since it is a Koine Greek dis legomenon found only in the New Testament passages Matthew 6:11 and Luke 11:3, its interpretation relies upon morphological analysis and context. The traditional and most common English translation is daily, although most scholars today reject this in part because all other New Testament passages with the translation "daily" include the word hemera (ἡμέρᾱ, 'day').

The difficulty in understanding epiousios goes at least as far back as AD 382. At that time, St. Jerome was commissioned by Pope Damasus I to renew and consolidate the various collections of biblical texts in the Vetus Latina ("Old Latin") then in use by the Church. Jerome accomplished this by going back to the original Greek of the New Testament and translating it into Latin; his translation came to be known as the Vulgate. In the identical contexts of Matthew and Luke—that is, reporting the Lord's Prayer—Jerome translated epiousios in two different ways: by morphological analysis as 'supersubstantial' (supersubstantialem) in Matthew 6:11, but retaining 'daily' (quotidianum) in Luke 11:3.

The modern Catholic Catechism holds that there are several ways of understanding epiousios, including the traditional 'daily', but most literally as 'supersubstantial' or 'superessential', based on its morphological components. Alternative theories are that—aside from the etymology of ousia, meaning 'substance'—it may be derived from either of the verbs einai (εἶναι), meaning "to be", or ienai (ἰέναι), meaning both "to come" and "to go".^:172

🔗 Books 🔗 Women's History

Around the World in Seventy-Two Days is an 1890 book by journalist Elizabeth Jane Cochrane, writing under her pseudonym, Nellie Bly. The chronicle details her 72-day trip around the world, which was inspired by the book, Around the World in Eighty Days by Jules Verne. She carried out the journey for Joseph Pulitzer's tabloid newspaper, the New York World.

🔗 Mathematics

In geometry, circle packing is the study of the arrangement of circles (of equal or varying sizes) on a given surface such that no overlapping occurs and so that no circle can be enlarged without creating an overlap. The associated packing density, η, of an arrangement is the proportion of the surface covered by the circles. Generalisations can be made to higher dimensions – this is called sphere packing, which usually deals only with identical spheres.

While the circle has a relatively low maximum packing density of 0.9069 on the Euclidean plane, it does not have the lowest possible. The "worst" shape to pack onto a plane is not known, but the smoothed octagon has a packing density of about 0.902414, which is the lowest maximum packing density known of any centrally-symmetric convex shape. Packing densities of concave shapes such as star polygons can be arbitrarily small.

The branch of mathematics generally known as "circle packing" is concerned with the geometry and combinatorics of packings of arbitrarily-sized circles: these give rise to discrete analogs of conformal mapping, Riemann surfaces and the like.

The Sweden Solar System is the world's largest permanent scale model of the Solar System. The Sun is represented by the Ericsson Globe in Stockholm, the largest hemispherical building in the world. The inner planets can also be found in Stockholm but the outer planets are situated northward in other cities along the Baltic Sea. The system was started by Nils Brenning and Gösta Gahm and is on the scale of 1:20 million.

🔗 Video games 🔗 Computer science 🔗 Science

A human-based computation game or game with a purpose (GWAP) is a human-based computation technique of outsourcing steps within a computational process to humans in an entertaining way (gamification).

Luis von Ahn first proposed the idea of "human algorithm games", or games with a purpose (GWAPs), in order to harness human time and energy for addressing problems that computers cannot yet tackle on their own. He believes that human intellect is an important resource and contribution to the enhancement of computer processing and human computer interaction. He argues that games constitute a general mechanism for using brainpower to solve open computational problems. In this technique, human brains are compared to processors in a distributed system, each performing a small task of a massive computation. However, humans require an incentive to become part of a collective computation. Online games are used as a means to encourage participation in the process.

The tasks presented in these games are usually trivial for humans, but difficult for computers. These tasks include labeling images, transcribing ancient texts, common sense or human experience based activities, and more. Human-based computation games motivate people through entertainment rather than an interest in solving computation problems. This makes GWAPs more appealing to a larger audience. GWAPs can be used to help build the semantic web, annotate and classify collected data, crowdsource general knowledge, and improving other general computer processes. GWAPs have a vast range of applications in variety of areas such as security, computer vision, Internet accessibility, adult content filtering, and Internet search. In applications such as these, games with a purpose have lowered the cost of annotating data and increased the level of human participation.

The Cosmopolitan Railway was a proposed global railroad network advocated by William Gilpin, formerly the first territorial governor of Colorado (1861–62), in his 1890 treatise Cosmopolitan Railway: Compacting and Fusing Together All the World's Continents. Gilpin named his capital city of Denver as the "railroad centre of the West".

🔗 Statistics

In statistics, Halton sequences are sequences used to generate points in space for numerical methods such as Monte Carlo simulations. Although these sequences are deterministic, they are of low discrepancy, that is, appear to be random for many purposes. They were first introduced in 1960 and are an example of a quasi-random number sequence. They generalize the one-dimensional van der Corput sequences.
