Science terminology consists of a list of physics or energy related terms.

Physics[edit | edit source]

"The branch of science concerned with the study of properties and interactions of space, time, matter and energy."
―Wiktionary
  • Celestial mass - See Celestial terminology for more information.
  • Electromagnetic radiation - A form of energy emitted and absorbed by charged particles. Different forms are determined by wavelength, including radio waves, visible light, and X-rays.
  • Energy - A quantity that denotes the ability to do work.
  • Force - A quantity denoting the ability to deform, orientate or accelerate an object in space.
  • Habitable zone - The range from a star where a liquid solvent can exist in all three phases of matter.  It is this region where complex, multicellular life forms can evolve naturally.
  • Ionising radiation - Radiation with the ability to remove electrons from atoms without requiring a temperature change. Commonly thought of as 'atomic radiation', and can cause radiation poisoning, cancer, etc.
  • Mass - The quantity of matter in a body.
  • Power - In the context of physics, the rate of change of energy over time. Measured in watts, which are equivalent to joules per second.
  • Tachyon - A type of particle that always moves faster than light.
  • Weight - The force on an object due to the gravitational attraction between it and the relevant astronomical object.

Chemistry[edit | edit source]

"The branch of natural science that deals with the composition and constitution of substances and the changes that they undergo as a consequence of alterations in the constitution of their molecules."
―Wiktionary
  • Atom - A building block of matter consisting of a nucleus consisting of protons and neutrons (except hydrogen-1, which has no neutrons) orbited by electrons.
  • Ion - An atom with a net charge, caused by either loss or gain of electrons.
  • Isotope - Atoms of an element which have differing numbers of neutrons. For example, deuterium is an isotope of hydrogen which has a single neutron as opposed to hydrogen-1's zero neutrons.
  • Molecule - Several atoms joined together in a specific structure.
  • pH - A measure of acidity or alkalinity (-log10[H+]). Neutral substances such as water have a pH of 7. Acids have low pHs and bases have high pHs.

Biology[edit | edit source]

"The study of life and living matter."
―Wiktionary
  • Biochemistry - The chemistry of compounds in living organisms and the processes they relate to, or the chemical characteristics of a particular organism.
  • Carnivore - An organism subsisting on meat.
  • Detrivore - An organism subsisting on non-living organic matter.
  • Evolution - The change of the genetic composition of a population over time.
  • Herbivore - An organism subsisting on plants.
  • Omnivore - An organism subsisting on both meat and plants.
  • Parasite - An organism subsisting on resources gathered or collected by or in another organism.
  • Liquivore - An organism that breaks down food into a liquid before ingestion.

Social sciences[edit | edit source]

  • Boltzmann entity - Boltzmann entities are sentient minds created from quantum fluctuations.
  • Sentience - Experiencing sensation, being aware of one's environment.
  • Sapience - The trait of possessing discernment and being able to apply relevant knowledge in an insightful manner.

Technology[edit | edit source]

  • FTL - Faster-than-light travel.
  • Megastructure - An artificial construct at least 1,000 kilometers in length.
  • Shields - a protective barrier around a spaceship
  • Sonic black hole - A phenomenon that absorbs phonons.
  • Wormhole - A corridor through space-time that allows instantaneous travel between two distant points.
