Science

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 (journal)

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.

Science (UIL test)

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.

Eligibility

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:

4-Chloromethcathinone

4-Chloromethcathinone (also known as 4-CMC and Clephedrone) is a stimulant drug of the cathinone class that has been sold online as a designer drug.

Legality

Clephedrone is an Anlage I controlled drug in Germany.

Sweden's public health agency suggested classifying 4-Chloromethcathinone (klefedron) as illegal narcotic on June 1, 2015.

As of October 2015 4-CMC is a controlled substance in China.

USS Wassuc (CMc-3)

USS Wassuc (CMc-3), originally a steel-hulled, coastal passenger vessel built in 1924 at Elizabethport, New Jersey, by the New Jersey Drydock and Transportation Corp. of New York City as SS Yale, was acquired by the U.S. Navy on 20 December 1940. SS Yale then began conversion to a coastal minelayer at the New York Navy Yard. Classified CMc-3 on 30 December 1940 and renamed USS Wassuc on 10 January 1941, the ship was commissioned at the New York Navy Yard on 15 May 1941.

East Coast operations

After commissioning, USS Wassuc proceeded south; touched at Norfolk, Virginia; and then sailed back northward to the Washington Navy Yard where she arrived on 4 June. She subsequently moved to the Mine Warfare School at Yorktown, Virginia, on 23 June, where she relieved USS Cormorant (AM-40), freeing that minesweeper to begin an overhaul. During her service at Yorktown, Wassuc participated in experimental mine work under the aegis of the Bureau of Ordnance (BuOrd).

Completing that tour in mid-August, Wassuc moved to the Marine Basin at Brooklyn, New York, for extensive alterations that were not completed until after the Japanese attack on Pearl Harbor had plunged the United States into World War II. Two days after Christmas of 1941, Wassuc departed Tompkinsville, Staten Island, New York, bound for Yorktown, Virginia, to receive mine warfare instruction duties and further work under the auspices of BuOrd.
