"Lessons" is the eighth episode of the first season of the HBO original series The Wire. The episode was written by David Simon from a story by David Simon and Ed Burns and was directed by Gloria Muzio. It originally aired on July 21, 2002.
One of Wallace's young charges wakes him for help with their math homework. Wallace appears unusually tired and irritable, but he awakes to assist with the child's school work anyway. The young kid is unable to do a simple story problem. Wallace asks a similar question, but uses the language of the drug business, instead of busses, which the kid solves in seconds. Poot shows up during the math lesson and encourages Wallace to come to work rather than lying around all day, which he has frequently been doing recently. He is reluctant and refuses to leave his room. He then asks to borrow money from Poot, who begrudgingly obliges. Afterward, Poot reports his concerns over Wallace's activities to D'Angelo, who wants to talk with Wallace face-to-face. Meanwhile, at the print shop (a Barksdale front), Stringer berates the staff for not acting like professionals.
2112 (pronounced "twenty-one twelve") is the fourth studio album by Canadian rock band Rush. Released on April 1, 1976, it features the seven-part title suite composed by Geddy Lee and Alex Lifeson, with lyrics written by Neil Peart telling a dystopian story set in the year 2112. It is sometimes described as a concept album although the songs on the second side are unrelated to the suite. Rush repeated this arrangement on the 1978 album Hemispheres.
2112 is one of two Rush albums listed in the book 1001 Albums You Must Hear Before You Die (the other being Moving Pictures). In 2006, a poll of Planet Rock listeners picked 2112 as the definitive Rush album. In 2012, it was ranked second on Rolling Stone's list of 'Your Favorite Prog Rock Albums of All Time', as voted for in a reader's poll, one of three Rush albums included (the others being Moving Pictures and Hemispheres).
A deluxe edition was released in 2012 as both a CD/DVD and a CD/Blu-ray. The CD featured the entire album remastered, as well as three live bonus tracks from their 1981 concert at Northlands Coliseum. The DVD and Blu-ray included the album in three different HD formats, as well as on-screen lyrics, liner notes, and a digital comic book depicting the story of the title track.
Science is a systematic enterprise that creates, builds and organizes knowledge in the form of testable explanations and predictions about the universe.
Contemporary science is typically subdivided into the natural sciences which study the material world, the social sciences which study people and societies, and the formal sciences like mathematics. The formal sciences are often excluded as they do not depend on empirical observations. Disciplines which use science like engineering and medicine may also be considered to be applied sciences.
During the middle ages in the Middle East, foundations for the scientific method were laid by Alhazen. From classical antiquity through the 19th century, science as a type of knowledge was more closely linked to philosophy than it is now and, in fact, in the West the term "natural philosophy" encompassed fields of study that are today associated with science, such as physics, astronomy and medicine.
In the 17th and 18th centuries scientists increasingly sought to formulate knowledge in terms of laws of nature. Over the course of the 19th century, the word "science" became increasingly associated with the scientific method itself, as a disciplined way to study the natural world. It was in the 19th century that scientific disciplines such as physics, chemistry, and biology reached their modern shapes. The same time period also included the origin of the terms "scientist" and "scientific community," the founding of scientific institutions, and increasing significance of the interactions with society and other aspects of culture.
Science, also widely referred to as Science Magazine, is the peer-reviewed academic journal of the American Association for the Advancement of Science (AAAS) and one of the world's top academic journals. It was first published in 1880, is currently circulated weekly and has a print subscriber base of around 130,000. Because institutional subscriptions and online access serve a larger audience, its estimated readership is 570,400 people.
The major focus of the journal is publishing important original scientific research and research reviews, but Science also publishes science-related news, opinions on science policy and other matters of interest to scientists and others who are concerned with the wide implications of science and technology. Unlike most scientific journals, which focus on a specific field, Science and its rival Nature cover the full range of scientific disciplines. According to the Journal Citation Reports, Science's 2014 impact factor was 33.611.
Although it is the journal of the AAAS, membership in the AAAS is not required to publish in Science. Papers are accepted from authors around the world. Competition to publish in Science is very intense, as an article published in such a highly cited journal can lead to attention and career advancement for the authors. Fewer than 10% of articles submitted are accepted for publication.
In the US state of Texas science is one of several academic events sanctioned by the University Interscholastic League. It is also a competition held by the Texas Math and Science Coaches Association, using the same rules as the UIL.
Science is designed to test students' knowledge of scientific fact, understanding of scientific principles and the ability to think through scientific problems.
Students in Grade 7 through Grade 12 are eligible to enter this event. Students in Grade 6 may compete with permission of the district executive committee, but can only compete in each junior high division (see below) only one time throughout their academic career.
For competition purposes, Grades 7 and 8 compete in separate divisions (Division I for Grade 7 and Division II for Grade 8) while Grades 9-12 compete together, with separate subjects covered on each test as follows:
