  2. SCIENCE
  3. -------
  4. scientific method:
  5. One possible way of getting knowledge in science, based on empiricism
  6. (acquiring information through our senses).
  7. Other ways (than the scientific method) of acquiring truth in science exist,
  8. e.g. deductive reasoning from axioms, which is based on rationalism rather
  9. than empirism.
  10. Scientific method means usually working in these steps:
  11. 1. Ask a question about the world.
  12. 2. Form a hypothesis based on the question.
  13. 3. Design an experiment to test the hypothesis.
  14. 4. Carry out the experiment.
  15. 5. Analyze the results and extract new knowledge from them.
  16. theory:
  17. An explanation of an aspect of the real world that can be tested using the
  18. scientific method. A theory can't be proven, only disproved or supported by
  19. evidence, using inductive reasoning.
  20. theorem:
  21. Statement which can be proven or disproven using deductive reasoning.
  22. - science:
  23. Systematic effort that searches for and organizes verifiable knowledge which
  24. can be used to make predictions about the universe.
  25. Some sciences can fall under multiple categories (e.g. linguistics can be
  26. a social science but also a formal science, depending on the specific
  27. subfield).
  28. Science (and its research) is eiter basic (studies the basic natural laws)
  29. or applied (applies basic knowledge in practice, e.g. medicine, technology,
  30. ...).
  31. - strict sciences:
  32. Use very reliable methods, principle and tools (scientific method,
  33. deductive reasoning, falsifyability, math, ...) of gaining knowledge.
  34. - formal sciences:
  35. Study the abstract formal languages of science, create tools to be used
  36. by other sciences, don't generally use scientific method and empiricism,
  37. though these can be used in their context too (e.g. "experiments with
  38. numbers"). Formal sciences produce theorems, which can (and should) be
  39. completely proven. Use deductive reasoning.
  40. - mathematics
  41. - logic
  42. - statistics
  43. - theoretical computer science
  44. - information theory
  45. - theoretical linguistics
  46. - empirical sciences:
  47. Primarily use the scientific method, produce theories, which can't be
  48. proven, only disproved or supported by evidence. Use inductive
  49. reasoning.
  50. - natural sciences:
  51. Try to be as exact as possible, maximize objectivity and minimize the
  52. influence of the observer, are highly skeptical, require
  53. falsifiability.
  54. - physics
  55. - chemistry
  56. - biology
  57. - medicine
  58. - earth sciences
  59. - social sciences:
  60. Study individuals and their relationships on a high level. While still
  61. using the scientific method and scientific principles, they allow
  62. other methods of gaining knowledge (speculation, ...), are not
  63. strictly exact, are more subjetive and allow the observer to interact
  64. with the subjects (which is often the only way to gain knowledge).
  65. - psychology
  66. - sociology
  67. - anthropology
  68. - history (partly)
  69. - archeology (partly)
  70. - economics
  71. - geography
  72. - linguistics
  73. - law
  74. - humanities:
  75. Study the aspects and products of human culture, do not use scientific
  76. method and so don't produce theories (nor theorems). The methods are
  77. speculative and critical.
  78. - philosophy
  79. - literature
  80. - religion
  81. - arts
  82. - history (partly)
  83. - archeology (partly)
  84. - pseudoscience:
  85. Something that tries to look like strict science but doesn't fit the
  86. definition of it.
  87. - astrology:
  88. Does not correctly predict the world, doesn't use scientific method, often
  89. gives unfalsifyable theories.
  90. - numerology
  91. - alchemy
  92. - flat earth theory
  93. - homeopathy
