Branches of Science
Branches of Science Classifying sciences involves arbitrary decisions because the universe is not easily split into separate compartments. This article divides science into five major branches: mathematics, physical sciences, earth sciences, life sciences, and social sciences. A sixth branch, technology, draws on discoveries from all areas of [...]
How Scientists Work
How Scientists Work Scientific research can be divided into basic science, also known as pure science, and applied science. In basic science, scientists working primarily at academic institutions pursue research simply to satisfy the thirst for knowledge. In applied science, scientists at industrial corporations conduct research to achieve some [...]
Greek and Roman Technologies
Greek and Roman Technologies The Persian Empire of Cyrus the Great was overthrown and succeeded by the empire of Greece's Alexander the Great. Greece had first become a power through its skill in shipbuilding and trading and by its colonization of the shores of the Mediterranean. The Greeks defeated the Persians, in part, because of their naval [...]
Science and Technology
Science and Technology The meanings of the terms science and technology have changed significantly from one generation to another. More similarities than differences, however, can be found between the terms. Both science and technology imply a thinking process, both are concerned with causal relationships in the material world, and both [...]
Hybrid Vehicles
Hybrid Gas-Electric Vehicles The weaknesses of batteries led to the marketplace failures of some pioneering electric cars such as General Motors’ EV1 and Honda’s EV Plus in the late 1990s. Customers refused to accept the limited range and power of these vehicles, and the manufacturers halted production. Development of such cars, however, [...]
New Blu-Ray Video Disk
New Blu-Ray video disk is made of paper A new type of Blu-Ray digital video disk made largely from paper has been developed by Sony and Toppan Printing in Japan. The two companies say such paper-based disks will be cheaper to make and less environmentally harmful. Blu-Ray disks, considered a successor to conventional DVDs, store data using [...]
Manhattan Project
Information of the Manhattan Project The beginnings of the Manhattan Project and atomic arms research and what caused its conception. In the 1930s scientists were finding very intriguing things about the use of the atoms power and atomic fission. Fission is the process by which the nucleus of a heavy element absorbs a neutron, which forces it [...]
What is a Robot?
What is a robot? Learn all about robots, including what kind of work they do, how they move, what they look like and more! Robots are not new. For many years, scientists have experimented with giving machines artificial intelligence, or computer brains. In the 1940's, crude computer-type machines were given the task of breaking codes. [...]
The Largest Optical Telescope
The Largest Optical Telescope What is the largest optical telescope; read about the keck telescope here! Measuring 387 inches and 9.82 m, the Keck telescope is known as the world's largest optical telescope. Formerly, the Hale telescope was the largest instrument of its kind until the Keck telescope was built in 1990. It is located at the [...]
The First Guided Missiles
The First Guided Missiles In 1898, a Russian physicist named Konstantin Tsiolkovsky (1857-1935) suggested that rockets could be used to travel to outer space. In those days all rockets were powered by solid fuel (chemical powders). Tsiolkovsky theorized that the use of liquid fuel would increase the range of the rockets. Tsiolkovsky is [...]
