Popular Science Toys For Kids

DNA ... DNA consists of two long polymers of simple units called nucleotides, with backbones made of sugars and phosphate groups joined by ester bonds. These two strands run in opposite directions to each other and are therefore anti-parallel...

Cryptography ... Modern cryptography is heavily based on mathematical theory and computer science practice; cryptographic algorithms are designed around computational hardness assumptions, making such algorithms hard to break in practice by any adversary...

NASA ... Since February 2006, NASA's mission statement has been to "pioneer the future in space exploration, scientific discovery and aeronautics research." On September 14, 2011, NASA announced that it had selected the design of a new Space Launch System that it said would take the agency's astronauts farther into space than ever before and provide the cornerstone for future human space exploration efforts by the U. S. NASA was established by the National Aeronautics and Space Act on July 29, 1958, replacing its predecessor, the National Advisory Committee for Aeronautics (NACA). The agency became operational on October 1, 1958...

Learning ... Human learning may occur as part of education, personal development, schooling, or training. It may be goal-oriented and may be aided by motivation...

Science ... This sometimes left the study of human thought and society in a linguistic limbo, which was resolved by classifying these areas of academic study as social science... Similarly, several other major areas of disciplined study and knowledge exist today under the general rubric of "science", such as formal science and applied science... History and philosophy History Science in a broad sense existed before the modern era, and in many historical civilizations, but modern science is so distinct in its approach and successful in its results that it now defines what science is in the strictest sense of the term...

Earth Science ... Beneath the Earth's crust lies the mantle which is heated by the radioactive decay of heavy elements. The mantle is not quite solid and consists of magma which is in a state of semi-perpetual convection...

Photography ... Photography has many uses for business, science, manufacturing (e.g. photolithography), art, and recreational purposes...

Holography ... The holographic recording itself is not a plain image – it consists of an apparently random structure of either varying intensity, density or profile. Overview and history The Hungarian-British physicist Dennis Gabor (Hungarian name: Gábor Dénes), was awarded the Nobel Prize in Physics in 1971 for "for his invention and development of the holographic method"...

Management ... Since organizations can be viewed as systems, management can also be defined as human action, including design, to facilitate the production of useful outcomes from a system. This view opens the opportunity to 'manage' oneself, a pre-requisite to attempting to manage others...

Photonics ... Photonics as a field began with the invention of the laser in 1960. Other developments followed: including the laser diode in the 1970s, optical fibers for transmitting information, and the Erbium-doped fiber amplifier...

Ubiquitous Computing ... This paradigm is also described as pervasive computing, ambient intelligence., where each term emphasizes slightly different aspects. When primarily concerning the objects involved, it is also physical computing, the Internet of Things, haptic computing, and things that think...

Social Network ... Social networks and the analysis of them is an inherently interdisciplinary academic field which emerged from social psychology, sociology, statistics, and graph theory. Jacob Moreno is credited with developing the first sociograms in the 1930s to study interpersonal relationships as structures in which people were points and the relationships between them were drawn as connecting lines...

Satellite ... The world's first artificial satellite, the Sputnik 1, was launched by the Soviet Union in 1957. Since then, thousands of satellites have been launched into orbit around the Earth; also some satellites, notably space stations, have been launched in parts and assembled in orbit...

Environment (biophysical) ... Environmental science Environmental science is the study of the interactions within the biophysical environment...

Biotechnology ... For thousands of years, humans have used selective breeding to improve production of crops and livestock to use them for food. In selective breeding, organisms with desirable characteristics are mated to produce offspring with the same characteristics...

Forensic Science ... However ancient sources contain several accounts of techniques that foreshadow the concepts of forensic science that is developed centuries later, such as the "Eureka" legend told of Archimedes (287–212 BC)...

Economy ... A given economy is the end result of a process that involves its technological evolution, history and social organization, as well as its geography, natural resource endowment, and ecology, as main factors. These factors give context, content, and set the conditions and parameters in which an economy functions...

The Arts ... Art is a global activity which encompasses a host of disciplines, as evidenced by the range of words and phrases which have been invented to describe its various forms. Examples of such phraseology include: Fine Arts, Liberal Arts, Visual Arts, Decorative Arts, Applied Arts, Design, Crafts, Performing Arts, and so on...
