  2. Patterns in nature - Wikipedia

    en.wikipedia.org/wiki/Patterns_in_nature

    Patterns in nature are visible regularities of form found in the natural world. These patterns recur in different contexts and can sometimes be modelled mathematically. Natural patterns include symmetries, trees, spirals, meanders, waves, foams, tessellations, cracks and stripes. [1] Early Greek philosophers studied pattern, with Plato ...

    en.wikipedia.org/wiki/List_of_natural_phenomena

    A natural phenomenon is an observable event which is not man-made. Examples include: sunrise, weather, fog, thunder, tornadoes; biological processes, decomposition, germination; physical processes, wave propagation, erosion; tidal flow, and natural disasters such as electromagnetic pulses, volcanic eruptions, hurricanes and earthquakes.

  4. Pareidolia - Wikipedia

    en.wikipedia.org/wiki/Pareidolia

    Pareidolia (/ ˌpærɪˈdoʊliə, ˌpɛər -/; [1] also US: / ˌpɛəraɪ -/) [2] is the tendency for perception to impose a meaningful interpretation on a nebulous stimulus, usually visual, so that one detects an object, pattern, or meaning where there is none. Pareidolia is a type of apophenia. Common examples include perceived images of ...

  5. Entoptic phenomenon - Wikipedia

    en.wikipedia.org/wiki/Entoptic_phenomenon

    Entoptic phenomena (from Ancient Greek ἐντός (entós) 'within' and ὀπτικός (optikós) 'visual') are visual effects whose source is within the human eye itself. (Occasionally, these are called entopic phenomena, which is probably a typographical mistake.) In Helmholtz 's words: "Under suitable conditions light falling on the eye ...

  6. Plant perception (physiology) - Wikipedia

    en.wikipedia.org/wiki/Plant_perception_(physiology)

    Plant perception is the ability of plants to sense and respond to the environment by adjusting their morphology and physiology. [1] Botanical research has revealed that plants are capable of reacting to a broad range of stimuli, including chemicals, gravity, light, moisture, infections, temperature, oxygen and carbon dioxide concentrations, parasite infestation, disease, physical disruption ...

  7. Phenology - Wikipedia

    en.wikipedia.org/wiki/Phenology

    Contents. Phenology. Not to be confused with Phrenology, Phonology, or Phenomenology. Phenology is the study of periodic events in biological life cycles and how these are influenced by seasonal and interannual variations in climate, as well as habitat factors (such as elevation). [ 1 ] Examples include the date of emergence of leaves and ...

  8. Pollination - Wikipedia

    en.wikipedia.org/wiki/Pollination

    Pollination. Pollination is the transfer of pollen from an anther of a plant to the stigma of a plant, later enabling fertilisation and the production of seeds. [1] Pollinating agents can be animals such as insects, for example beetles or butterflies; birds, and bats; water; wind; and even plants themselves.

  9. Irreducible complexity - Wikipedia

    en.wikipedia.org/wiki/Irreducible_complexity

    Irreducible complexity (IC) is the argument that certain biological systems with multiple interacting parts would not function if one of the parts were removed, so supposedly could not have evolved by successive small modifications from earlier less complex systems through natural selection, which would need all intermediate precursor systems to have been fully functional.
