system science

It is an interdisciplinary area, which includes studying complex systems in society, science and nature. It focuses on developing interdisciplinary foundations for use in areas including biology, engineering, social sciences and medicines. It is a scientific discipline, which is based on a range of thinking systems that include the chaos theory, control theory, complex systems, cybemetics, systems biology, system psychology, systems ecology, systems engineering and sociotechnical systems. If you are planning to study this interdisciplinary subject, make sure that you have the right information about its scope. These days system concepts find an extensive use for both research as well as applied purposes. The demand for professionals in this field is considerably high. Both the government and the industry need expert systems professionals, who can manage complicated technical and social systems. You can be one of those professionals, provided you possess the required skills to use the m

fundamental concept of string theory

The one that attracts me is the string theory. According to this theory the fundamental unit of all the substances is a mass less, extensible string. This theory is based on the extension and contraction of the string with the suitable changes in the energy.This theory attracts because of its power to explain the yet unexplainable facts. The first thing it can explain is the soul which is not yet accepted by science. But through this theory we can have a greater understanding of soul. Suppose the soul to be a string having certain energy. It can expand or contract according to the changes in the frequency (related to energy by E=hν). And it is a well known fact that our thoughts are like waves which travel through the mind and have certain frequencies. With the positive thoughts (meaning higher frequency) the energy of the soul increases and hence it expands and so our spirituality. Similarly if negative thoughts such as greed, lust, anger etc. pass through our mind then they will cont

intresting news about telescopes

Astronomy for kids can be rewarding, educational and of course fun too. With astronomy software children can take a virtual tour of our galaxy from their computer. For the hands on astronomer there are a number of telescopes for beginners available. From the simple reflecting telescope to the motorized equatorial mount refractor on up to the GOTO computerized telescope that will automatically point to any object in the night sky simply by entering information in the hand held computer keyboard. Any parent's job is to encourage children to want to learn. Who among us can look at the star filled heavens in amazement and not be filled with questions. School does not have to be boring when the whole universe can be a classroom. Take advantage of any interest your children show in star gazing and turn it into a life long educational pursuit. Who knows where it may lead too. For all you know your child may have the next Galileo or the astronaut that will colonize mars. But before we get

science Vs Technology

Science is search for the profound knowledge. Scientists investigate the world around us. They observe how things work and develop ideas about ways to make them work better. Sometimes they try to test an idea to explain how something works. Scientists perform experiments to find out how things work. The knowledge that they discover is useful for many things. It can help to build new machines. It can help scientists to develop new medicines or cure a disease. Technology is the use of scientific knowledge to create new things. An inventor is a person who creates a new idea or device to perform a task. An invention is the new technology created. An inventor with a new idea or design for an invention may decide to have the idea protected. The idea gets protection from the law in a paper called a patent. A patent prevents other people from making, using, or selling the new idea without permission from the inventor. Some inventions are simply a better way of doing or building something. They

fuel coming from water?

As the price of petroleum hits the roof, the search is on for alternative sources of clean, renewable energy. One promising candidate that's a ray of sunshine in our otherwise energy-scarce planet is none other than the sun.The technology is already available to tap this ever abundant power source. But as many of you already know, the sun isn't always shining. Once an overcast cloud sets in, the power meter drops back to zero. So researchers have turned to another more viable and abundant resource: water. If you still remember your high school chemistry, a water molecule is made up of two basic elements, namely, hydrogen and oxygen. Hydrogen is a highly combustible gas, most especially in the presence of oxygen. Due to its highly combustible quality, hydrogen has been commonly used as rocket fuel just ask NASA.In fact, if you've figured out a way to split a water molecule into its component elements, hydrogen and oxygen, and then burn these gases together to produce energy,

planet earth

One would have to come from outside the planet to discover Earth. There has been no one so far who said that Earth was discovered by aliens. In fact, planet Earth has been in the universe for a long time before humans existed.Earth is the third planet from the sun and was known by the Ancient Egyptians, Sumerians and the Greeks. Early humans thought that Earth was at the center of the universe and other planets, suns, stars and moons rotated around the Earth. The Earth was believed to be flat by the Arabs and Vikings. Early astronomers faced few problems, they noticed that some planets did not move in a straight trail and some stopped while moved backwards. Ptolemy concluded that other planets orbited inside little spheres and these spheres rotated around Earth.Nicolaus Copernicus proposed in the 16th century that Earth and the planets revolved around the sun instead. He had come up with a model of a solar system. His observations were based on Galileo's model. Some scientists from

basic structure of the atom

Let's start with the basic structure of the atom. Every atom has a nucleus that contains protons which are positively charged with negatively charged electrons in orbitals around the nucleus. The number of protons is equal to the number of electrons so that the atom overall is neutral. Now electrons will be in the lowest energy orbital that is possible to be stable. This will be the orbital closest to the nucleus. Let's take lithium as an example. Lithium is the third element in the periodic table and has three protons and three electrons. Two electrons are in an orbital close to the nucleus. This orbital can only hold two electrons as it is has a small radius. So the third electron goes in an orbital a bit farther away from the nucleus. We say that lithium has an electronic configuration of 2,1. An electronic configuration is just a way of saying where the electrons are! Now there are lots more orbitals further away from the nucleus that are empty in the case of lithium. They
