Sandstorm (vehicle)

Sandstorm is an autonomous vehicle created by Carnegie Mellon University's Red Team, for the 2004 and 2005 DARPA Grand Challenge competition. It is a heavily modified 1986 M998 HMMWV.

Sandstorm qualified in first position in the 2004 DARPA Grand Challenge. It traveled the fastest and farthest (7.4 miles) during the race before high centering on an embankment.

The sensors used by Sandstorm in 2004 included three fixed LIDAR laser-ranging units, one steerable LIDAR (in the globe on top), a radar unit (developed in collaboration with the Duke University Robotics Team), and a pair of cameras for stereo vision. Sandstorm also had an Applanix POS/LV system, providing a GPS and inertial navigation system for determining geographical position.

Since the 2004 race Sandstorm has been continually tested and modified, logging hundreds of test miles. Testing includes an unprecedented continuous 200 mile test run at an average of 28 miles per hour.

The 2005 version of Sandstorm used six fixed LIDAR units, the steerable LIDAR, and short- and long-range radar.

Sand Storm (video game)

Sand Storm is a 1992 action game in which you are shooting an anti-air ballistic weapon. The premise of the game is similar to that of Sabotage. You must defend your home base from planes (which drop bombs), Patriot Missiles, and Scuds. If a missile or bomb touches the ground, some of the buildings in the base are damaged. Each building can be damaged three times. In other missions, you can direct a missile into designated enemy buildings.

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.
