Science and human knowledge
Science is the overall system of human knowledge. It's acquired by observation of processes and phenomena in nature and society, processed rational, scientifically acceptable methods. It is an objective, systematized and argumentative knowledge of the laws, facts, phenomena and their probable causes. Verified by observation, experiment and correct thinking. It is not just a collection of knowledge. Also a way of thinking and seeing reality, based on reason, logic, criticism, doubt, objective, free and independent thinking. Science is also an objective, systematic, logical, precise and verifiable method (method of collecting, describing, classifying, defining, measuring, experimenting, explaining and evaluating empirical fact). It's main characteristics are objectivity, systematization, argumentation or verifiablity, logic and precision.
Branches of Science as human knowledge
Some of the branches are astronomy, mathematics, physics, quantum physics, technology, biology, chemistry, geology, psychology and other. Some fields of science see nature as matter in motion, obeying certain laws of nature. For this reason the most fundamental science is generally understood to be physics (knowledge of nature).Physics is a natural science that deals with movement, energy and matter. Through theory, physicists are doing experiments. Experiments are investigate phenomena. Theory describing the physical phenomena in a simplified mathematical models. Laws are expressed in mathematical form. The experiments give results through measurements and comparisons with the results of the count given by the theory. The theory most well anticipated results of experiments in a wider area and makes the laws of physics. Laws are subject to change and restrictions if a later more accurate and more extensive experiments show that this is necessary. The goal is to find the laws that describe the substance, motion and energy of the tiny microscopic subatomic level, to large macroscopic level.
The foundations of physics laid the Isaac Newton and Galileo Galilei discovering the laws of mechanics in the 16th and 17th centuries. There are several types such as classical, the theory of relativity, quantum, mechanics, thermodynamics, nuclear and other branches of physics.
Humanity at the beginning of development selected the wrong technology and the use of fossil fuels, which resulted in irreversible pollution of nature. In addition, consummation of the invention has not been carried out with a rational purpose. This is why rational technology is needed from materials that can be recycled, which would be as close as possible to the nature.

Water
Water is an element without which there is no life we know. In fact, the two oldest ways to find water are rivers and rainwater storage. With technology is also possible to get water. These are high concentration photo heat and water condensing systems.
Food
Food is the second element without which there is no life we know. Of course, the best quality food is growing in nature. Technologies that can be of help in obtaining food are watering and processing plants of planted vegetables and fruit in ground. There are also devices for preparing and storing food. Foods should be equally distributed in all parts of the Planet and should stop food throwing.
Clothing
For different weather conditions ranging from summer to winter, we need equipment for making clothing and footwear, so that we can protect us.
Medication
To have good health, medicines for various diseases are needed. For instance, this is helped by devices for the detection of diseases, operations and drug production.
House
The best houses are made of natural materials, such as wood, stone and glass. This materials are top quality and are considered to be highly energy efficient.
Electrical current
By using technology, humankind is moving towards the ability to create a home that will be completely independent and ecologically adapted to nature. For now, it can not be completely independent (if we include power heating), due to current technologies that can not produce enough energy in all parts of our Planet. The mentioned technologies that produce electricity are solar, wind and hydro power. For now, the closest to this goal is high concentration photovoltaic thermal system, smart flower, electric solar windows, semi-flexible panels and classic solar panels that use solar energy to produce electricity. For wind energy are used wind turbines with special propellers and a classic wind turbine. There are also water turbines that can be used in rivers and in the sea. In addition to this, there are generators and power saving devices. In the wild you can use devices with thermo-electric technology for charging battery (mobile phone, computer, GPS).
Transportation
The problem of today are fossil fuels, that are used for transport and so pollute the nature. It's therefore recommended to transport with electricity that does not pollute the environment. Perhaps the future also brings air transport in a safe and fast way, so there is no need to build roads.
Orientation
In order to be able to navigate at a greater distance in nature, orientation is required. For example, it used to be the Sun, the Stars and the signs of nature. Devices with which this is enabled with great precision are GPS, maps and compass.
Packaging
One of the biggest environmental problems is plastic packaging. Plastics take several hundreds to several thousand years to break down. Much is used to store food and other products. It would be best to make the packaging of glass, hemp and other natural materials.
Information
Information and energy is a very important part of the world that surrounds us. The devices that came into being and most of the technology that humanity has created is possible with computers. Using information and knowledge without computers today is unthinkable. Soon there will be a big turnaround in the emergence of quantum computers that will be many times faster and smarter.
