Science and its branches; things I'm interested in.

This is an extensive list of my interests in the scientific field. I've mentioned a few on my profile already in the "Who I'd Like To Meet" section but they will be mentioned again and explored further with a small explanation on what they actually are (in case anyone reading this does not know).

There are three main branches of science (Natural Sciences, Social Sciences, and Formal Sciences), those branches divide in sub-branches which then divide in other smaller branches.

• Natural Sciences study the nature of our physical world and the universe. Likewise, they are divided in three main branches: Physics, Chemistry and Biology.

• Social Sciences study human societies from across the globe along with the relationship of human beings with their social environment. The main branches are: Psychology, Sociology, Anthropology, Economics, Archaeology, History, Geography, Law, Politics.

• Formal Sciences use formal systems to produce knowledge and explore the nature of different disciplines. The most important branches are: Mathematics, Logic, Computer Science, Data Science, Statistics, Systems Science, Artificial Intelligence, Information Technology.

Now that we've finished our introduction to the main branches of science, let's start explaining the ones I actually take interest in (this is going to be an alphabetical list rather than a "more important to less important" list). Omitting only a few sub-divisions, they are:

• Acoustics: known as the science of sound. It studies the mechanical waves passing through matter. It studies vibrations and focuses on the production, control, transmission, reception, and effects of sound. It studies concepts like ultrasound and infrasound.

• Aerodynamics: the science of movement in a flow of air or gas. It deals with the motion of air and other gaseous fluids and with the forces acting on bodies passing through such a fluid. It focuses mainly on explaining the principles guiding the flight of aircraft, rockets, and missiles.

• Aerostatics: known as the science of air pressure. It studies the equilibrium of gases (such as air) and the equilibrium of solid bodies floating in gas-filled spaces. An example of those studies are hot-air balloons.

• Algebra: study of algebraic structures and manipulation of statements within those structures. In simple terms, algebra is the branch of mathematics which deals with abstract symbols rather than numbers.
  For example: a + b = c

• Asteroseismology: the study of the internal structures of stars by means of their intrinsic global oscillations (or study of stellar oscillations). It focuses on tracking the oscillations of stars, which are characterized by their frequencies, typical lifetime, amplitudes and mode identification. These oscillations are determined by the stellar interior, which it is possible to determinate the structure of the observed star thanks to them.

• Astrobiology: study of extraterrestrial life. It combines the knowledge and techniques from many fields, including astronomy, biology, chemistry, geology, atmospheric science, oceanography and aeronautical engineering. Which means it deals with subjects such as the environment necessary for life to survive, the limits under which life can survive, what life might look like on another planet, and more.

• Astrobotany: study of plants in space. It revolves around the need to understand how plants adapt and respond to spaceflight and how they are affected by space environmental stress.

• Astrodynamics: the study of the motion in space of natural and artificial bodies upon which the major force is gravity. The motion observed is the trajectory, which is a key design parameter that influences the characteristics of the mission, including coverage or operational areas, ability to be accessed from Earth, launch vehicle selection, amount of time the spacecraft spends in sunlight, and its exposure to charged particle radiation. 

• Astrogeology: study of extraterrestrial geology. It deals with the geology of the solid bodies in the solar system, such as the asteroids and the planets and their moons.
  These studies are then compared to the ones of Earth's geology to see its evolution process against the one of the other planets. 

• Astronomy: the study of everything in the universe beyond Earth’s atmosphere. That includes objects we can see with our naked eyes, like the Sun, the Moon, the planets, and the stars. It also includes objects we can only see with telescopes or other instruments, like faraway galaxies and tiny particles.

• Astrophysics: study of behaviour of interstellar matter. It's branch of space science that applies the laws of physics and chemistry to seek to understand the universe and our place in it. The field explores topics such as the birth, life and death of stars, planets, galaxies, nebulae and other objects in the universe. 

• Cartography: the art and science of graphically representing a geographical area, usually on a flat surface such as a map or chart. It may involve the superimposition of political, cultural, or other nongeographical divisions onto the representation of a geographical area.

• Chaology: study of chaos or chaos theory (commonly known as the butterfly effect). Chaos theory states that within the apparent randomness of chaotic complex systems, there are underlying patterns, interconnection, constant feedback loops, repetition, self-similarity, fractals and self-organization.

• Chemistry: study of properties and behaviours of substances. It deals principally with the properties of substances, the changes they undergo, and the natural laws that describe these changes.

• Cosmochemistry: the study of extraterrestrial materials aimed at understanding the nature of the bodies in our solar system. Research in cosmochemistry covers an enormous range of disciplines and techniques, including mineralogy, petrology, major and trace element chemistry, isotope compositions, radiometric ages, magnetism, and radiationexposure effects.

• Cosmology: the study of the origin, development, structure, history, and future of the entire universe. Cosmology is divided into two branches. Observational cosmology studies the universe using telescopes and other equipment to examine the direct evidence of the universe’s development and structure. Physical cosmology studies the structures and development of the universe and the physics that created them. It uses a mix of theory and experiments to construct and research cosmological models.
  Cosmology draws on advances from many scientific disciplines, including astrophysics, plasma physics, nuclear physics, particle physics, relativity, and quantum mechanics.

• Criminology: Criminology is the study of crime and criminal behavior, informed by principles of sociology and other non-legal fields, including psychology, economics, statistics, and anthropology.

• Dynamics: a branch of physics that examines the influences on the motion of an object. Physics examines the relationships between physical properties and forces and their manifestations in interactions between objects. The four main elements of dynamics are mass, energy, momentum, and force.

• Gemology: the scientific study of gemstones. They study their structure and reactions to stressors (heat, pressure, etc...) and how to identify them. 

• Geometry: a branch of mathematics concerned with properties of space such as the distance, shape, size, and relative position of figures. It is one of the oldest branches of mathematics, having arisen in response to such practical problems as those found in surveying, and its name is derived from Greek words meaning “Earth measurement.” 

• Graphology: the study of the way that people make letters and words when writing by hand. This is sometimes used to learn something about a person's character.

• Mathematics: the science of structure, order, and relation that has evolved from elemental practices of counting, measuring, and describing the shapes of objects. It deals with logical reasoning and quantitative calculation, and its development has involved an increasing degree of idealization and abstraction of its subject matter.

• Mechanics: science concerned with the motion of bodies under the action of forces, including the special case in which a body remains at rest. Of first concern in the problem of motion are the forces that bodies exert on one another. This leads to the study of such topics as gravity, electricity, and magnetism, according to the nature of the forces involved. 

• Mineralogy: scientific discipline that is concerned with all aspects of minerals, including their physical properties, chemical composition, internal crystal structure, and occurrence and distribution in nature and their origins in terms of the physicochemical conditions of formation.

• Mycology: the study of fungi, a group that includes the mushrooms and yeasts. Many fungi are useful in medicine and industry.

• Neuropsychology: the branch of science that studies the physiological processes of the nervous system and relates them to behaviour and cognition, in terms both of their normal function and of the dysfunctional processes associated with brain damage.

• Palaeontology: scientific study of life of the geologic past that involves the analysis of plant and animal fossils, including those of microscopic size, preserved in rocks. It is concerned with all aspects of the biology of ancient life forms: their shape and structure, evolutionary patterns, taxonomic relationships with each other and with modern living species, geographic distribution, and interrelationships with the environment.

• Physics: the science which deals with the structure of matter and the interactions between the fundamental constituents of the observable universe. In poorer words, physics is the science which studies matter (any substance that has mass and takes up space by having volume), its fundamental constituents, its motion and behaviour through space and time, along with the related entities of energy and force.

• Psychology: scientific discipline that studies mental states and processes and behaviour in humans and other animals.

• Psychopathology: the study of mental disorders and unusual or maladaptive behaviours. An understanding of the genesis of mental disorders is critical to mental health professionals in psychiatry, psychology, and social work.

• Psychophysics: study of quantitative relations between psychological events and physical events or, more specifically, between sensations and the stimuli that produce them.

• Quantum physics: discrete natural unit, or packet, of energy, charge, angular momentum, or other physical property. Light, for example, appearing in some respects as a continuous electromagnetic wave, on the submicroscopic level is emitted and absorbed in discrete amounts, or quanta; and for light of a given wavelength, the magnitude of all the quanta emitted or absorbed is the same in both energy and momentum. 

• Robotics: design, construction, and use of machines (robots) to perform tasks done traditionally by human beings.

• Theology: philosophically oriented discipline of religious speculation and apologetics that is traditionally restricted, because of its origins and format, to Christianity but that may also encompass, because of its themes, other religions, including especially Islam and Judaism. The themes of theology include God, humanity, the world, salvation, and eschatology (the study of last times).

• Thermodynamics: science of the relationship between heat, work, temperature, and energy. In broad terms, thermodynamics deals with the transfer of energy from one place to another and from one form to another. The key concept is that heat is a form of energy corresponding to a definite amount of mechanical work.

And that's all! If anyone reading this is interested in any of these; I'd love to be friends (if we aren't already).

(Keep in mind: I am not an expert in any of these fields. I'm just a guy who's interested in science and every once in a while goes ahead to learn new things about it.)
