Quantum Mechanics Atomic Physics And Molecular Physics
Quantum mechanics is the branch of physics treating atomic and subatomic systems and their interaction based on the observation that all forms of energy are released in discrete units or bundles called “quanta“. Remarkably, quantum theory typically permits only probable or statistical calculation of the observed features of subatomic particles, understood in terms of wave functions. The Schrödinger equation plays the role in quantum mechanics that Newton’s laws and conservation of energy serve in classical mechanicsi.e., it predicts the future behavior of a dynamic systemand is a wave equation that is used to solve for wavefunctions.
For example, the light, or electromagnetic radiation emitted or absorbed by an atom has only certain frequencies , as can be seen from the line spectrum associated with the chemical element represented by that atom. The quantum theory shows that those frequencies correspond to definite energies of the light quanta, or , and result from the fact that the electrons of the atom can have only certain allowed energy values, or levels when an electron changes from one allowed level to another, a quantum of energy is emitted or absorbed whose frequency is directly proportional to the energy difference between the two levels. The further confirmed the quantization of light.
The Main Branches Of Science
Mainly Science is divided into four main branches. They are,
- Natural Sciences
- Formal Sciences
- Applied Sciences
Each of these branches has sub-branches according to the nature of the subject. And also, there are overlapping science subjects. These subjects build with two sub-branches of the above main subject areas. The Formal Sciences act as a tool for both Natural and Social Sciences to build the applied science area. As I mentioned above, all of these areas are bound with each other.
If you are a student you may study about biology, Chemistry and Physics under the name of science subject. So, Sometime you may say these three subjects are the main branches of science. But these three study areas are only sub-branches of the natural sciences. All of the general people indeed see science through only these three main windows. But when we consider all of the studies, it can identify these four major categories.
If you are going to talk about only about chemistry, biology, and physics. You have to divide these three gems under Life science and Physical science, sub-branches of natural sciences. Next, lets see about this main subject.
Basic Principles Of The Physical Sciences
The foundations of the physical sciences rests upon key concepts and theories, each of which explains and/or models a particular aspect of the behaviour of nature. As in other sciences, these key concepts and theories came to discovery using the scientific method, which must be found using scientific evidence:

2 Physics A branch of science that involves the study of the physical world: energy, matter, and how they are related
3 Physics In physics, equations are important tools for modeling observations and for making predictions. Mathematics is the language of physics.
4 Measurements The Système International dUnités, or SI, uses seven base quantities, which are shown in the table below.
5 SI The base quantities were originally defined in terms of direct measurements. Other units, called derived units, are created by combining the base units in various ways. Ex. Speed , Newton , Volume The SI system is regulated by the International Bureau of Weights and Measures in Sèvres, France. This bureau and the National Institute of Science and Technology in Gaithersburg, Maryland, keep the standards of length, time, and mass against which our metersticks, clocks, and balances are calibrated.
6 SI Prefixes are used to change SI units by powers of 10, as shown in the table below.
7 MKS The MKS system of measurement is used in physics. MKS stands for meters, kilograms, seconds All measurements must be converted to meters, kilograms, and seconds
8 Measurements A measurement is a comparison between an unknown quantity and a standard. Measurements quantify observations. Careful measurements enable you to derive the relation between any two quantities.

Artificial intelligence, known as AI, is a field of computer science that looks at machines and their abilities as far as intelligence goes. Machines don’t have natural knowledge like humans do instead, they build knowledge by perceiving their environment.
Citizen science is research conducted by amateur or nonprofessional scientists. It can also be called public participation, and it is expected to grow in popularity thanks to technological advances that are available to laypeople.
What Are The Differences Between The Two Main Branches Of Physical Science
Though there is overlap between them, physics concerns the movement of physical objects in time, while chemistry concerns the transformation of physical matter from one type to another. Both are concerned with what matter is made of, but generally, physics looks at this question on a much smaller scale.

It Began With Isaac Newton
Prior to Newton, astronomers described the motions of “heavenly bodies,” as they were then called, using complex mathematical models without a physical basis. Newton showed that a single theory, describing what we now know as gravity, simultaneously explains the orbits of moons and planets in space and the trajectory of a cannonball on Earth. This added to the body of evidence for the startling conclusion that the “heavens” and Earth are subject to the same physical laws.
Perhaps what most separated Newton’s model from previous concepts, however, is that his theory was predictive as well as descriptive. Based on aberrations in the orbit of Uranus, astronomers predicted the position of a new planet, which was then observed and named Neptune.
Who Is Father Of Science
Galileo GalileiGalileo Galilei pioneered the experimental scientific method and was the first to use a refracting telescope to make important astronomical discoveries. He is often referred to as the father of modern astronomy and the father of modern physics. Albert Einstein called Galileo the father of modern science.

What Are The Formal Sciences
The difference between natural science and formal science is, at formal science, all theories are not going to prove with the real word like natural sciences. All theories in formal science come with human imaginations. Lets see the major areas of formal science.
All of the above sciences are need to be study under the care and according to a system. For this, mathematics can be used as a tool.
For study about the most intelligent activities, the Logic is used. Therefore this subject area is used for computer science as a tool.
All scientific researches need the statistics as a tool to organize and analyze the data and results of the study.
Subjects like economics, philosophy study under the decisions.

The Major Branches Of Science
Science is a systematic study of the nature and manners of an object and the natural universe that is established around measurement, experiment, observation and formulation of laws. There are four major branches of science each branch is categorized in different type of subjects that covers different areas of studies such us chemistry, physics, math, astronomy etc. The four major branches of science are, Mathematics and logic, biological science, physical science and social science.
The first branch is mathematics & logic. Mathematics and logic deals with abstract concepts. It goes hand in hand as both are needed in relation to finding out how social sciences and natural sciences work. They are also both needed in forming laws, theories and hypothesis. Even scientist needs this branch of science, as they would not come to a conclusion without any formulation.
Another branch of science is Biological science. This on the other hand deals with the study of living things. Biological science is divided into different sub topics. One of them is Zoology. It is a category under biology that focuses on the study of animal life. The study includes, and are not limited to, evolution, classification of both extinct and the living, structure and habits. Zoology also deals with embryology, which is the study of the animals’ development of the embryo, from fertilization to fetus.
What Is Earth Science
Earth science is a field of natural science that deals with the materials of the earth and its atmosphere. People who work in earth science can contribute to the societal understanding of the earth and how humans can protect it. There are many earth science types and career applications. Some types of earth science include meteorology, geology, oceanography and environmental science. Earth science is a popular career field, and it contains many career options, including:

Differences From Other Sciences
One reason why mathematics enjoys special esteem, above all other sciences, is that its laws are absolutely certain and indisputable, while those of other sciences are to some extent debatable and in constant danger of being overthrown by newly discovered facts.
As opposed to empirical sciences , the formal sciences do not involve empirical procedures. They also do not presuppose knowledge of contingent facts, or describe the real world. In this sense, formal sciences are both logically and methodologically a priori, for their content and validity are independent of any empirical procedures.
Therefore, straightly speaking, formal science is not an empirical science. It is a formal logical system with its content targeted at components of experiential reality, such as information and thoughts. As Francis Bacon pointed out in the 17th century, experimental verification of the propositions must be carried out rigorously and cannot take logic itself as the way to draw conclusions in nature. Formal science is a method that is helpful to empirical science but cannot replace empirical science.

Physical science is an encompassing term for the branches of natural science, and science , that study non-living systems, in contrast to the biological sciences. However, the term “physical” creates an unintended, somewhat arbitrary distinction, since many branches of physical science also study biological phenomena. Note that neither mathematics nor engineering belong to the sciences. Basic physical science topics include:
- Astronomy – the study of the universe beyond the atmosphere of the Earth
- Chemistry – the science dealing with the composition of substances, their interactions with energy and each other
- Many of the earth sciences, including:
- Geology – the study of the planetary structure of Earth and the physical processes which shape it
- Hydrology – the study of the movement and distribution of water across the Earth’s surface
- Meteorology – the study of weather patterns and other atmospheric phenomena
- Oceanography – the study of the ocean as a physical system
- Soil science – the study of the pedosphere
In What Branch Of Science Does Technology Belong
The question may be found in the following link. I have been asked in the comments to provide my question on this Stack Exchange site.
Actually, technology per se isn’t science. But then, neither is mathematics. Technology is normally about the creation of things. Science is about using a certain methodology for trying to discern the truth about the world and natural processes. If you define natural processes broadly, including human processes, then social science is also science.
But mathematics is about using logical process to explore the implications of basic assumptions .
But both science and mathematics are about ideas, whereas technology is about things.
Technology, as in iPhones and respirators and all, is about the creation of useful things. That is basically why you can patent inventions, but you can only copyright scientific papers.
Some sorts of technology, say vaccines, depend on science to assure safety and efficacy. And some sorts of technology depend on mathematics, such as computers and bitcoin.
Computer Science has elements of both science and technology. But one normally gets a PhD in CS for discoveries on the scientific side, even if the science is an exploration of something created on the technological side. CS actually has elements of mathematics as well, such as in algorithm analysis and computability theory.
