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:
Le vent dans les arbres d'automne,
Le piano muet qui s'étonne
Et ton souvenir dans mon coeur
Comme au printemps bougent les fleurs,
J'aurai beau le taire ou le dire,
Ma vie ne saurait être pire
Que ce manège déserté
Où plus rien ne viendra chanter.
Sans toi, cette vie m'emprisonne, sans toi, je ne suis plus personne
Que Noël carillonne ou pas, tu ne reviendras pas.
Ces trottoirs où la pluie voltige,
Le piano muet qui s'afflige,
Et ton souvenir dans mes yeux
Ca m'empêche de croire en Dieu.
J'aurai beau le dire ou le taire
De tous les bonheurs de la terre,
Celui que ta main m'a donné
N'aura pas de nouvelle année
Sans toi, cette vie m'emprisonne, sans toi, je ne suis plus personne
Que Noël carillonne ou pas, tu ne reviendras pas.
Cette neige sous les auspices
Et ce piano comme au supplice
Et ma voix là-bas qui se perd
Comme une vague sur la mer,
J'aurai beau le dire ou le taire,
Il y a quelque part un mystère
Quelque part une ombre qui dort,
Quelque part un autre décor.
Sans toi, cette vie m'emprisonne, sans toi, je ne suis plus personne
Que Noël carillonne ou pas, tu ne reviendras pas.
Sans toi, cette vie m'emprisonne, sans toi, je ne suis plus personne
