  2. Symmetry in biology - Wikipedia

    en.wikipedia.org/wiki/Symmetry_in_biology

    Symmetry in biology refers to the symmetry observed in organisms, including plants, animals, fungi, and bacteria. External symmetry can be easily seen by just looking at an organism. For example, the face of a human being has a plane of symmetry down its centre, or a pine cone displays a clear symmetrical spiral pattern.

  3. A Guide to the Scientific Knowledge of Things Familiar

    en.wikipedia.org/wiki/A_Guide_to_the_Scientific...

    The object of The Guide to Science was to present answers to over 2000 questions about common phenomena. [1] There are questions dealing with man-made objects such as candles, stoves and chimneys, as well as answers seeking to explain natural phenomena such as thunder, lightning (including a mention of ball lightning [7]), clouds, dew, and ...

  4. Chirality - Wikipedia

    en.wikipedia.org/wiki/Chirality

    Many other familiar objects exhibit the same chiral symmetry of the human body, such as gloves, glasses (sometimes), and shoes. A similar notion of chirality is considered in knot theory, as explained below. Some chiral three-dimensional objects, such as the helix, can be assigned a right or left handedness, according to the right-hand rule.

  5. Recognition-by-components theory - Wikipedia

    en.wikipedia.org/wiki/Recognition-by-components...

    The recognition-by-components theory suggests that there are fewer than 36 geons which are combined to create the objects we see in day-to-day life. [3] For example, when looking at a mug we break it down into two components – "cylinder" and "handle". This also works for more complex objects, which in turn are made up of a larger number of geons.

Animal Locomotion: An Electro-photographic Investigation of Consecutive Phases of Animal Movements is a series of scientific photographs by Eadweard Muybridge made in 1884 and 1885 at the University of Pennsylvania, to study motion in animals (including humans).

  7. Pareidolia - Wikipedia

    en.wikipedia.org/wiki/Pareidolia

    Satellite photograph of a mesa in the Cydonia region of Mars, often called the "Face on Mars" and cited as evidence of extraterrestrial habitation. Pareidolia (/ ˌ p ær ɪ ˈ d oʊ l i ə, ˌ p ɛər-/; [1] also US: / ˌ p ɛər aɪ-/) [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 ...

  8. Visual agnosia - Wikipedia

    en.wikipedia.org/wiki/Visual_agnosia

    At an associative level, the meaning of an object is attached to the perceptual representation and the object is identified. [2] If a person is unable to recognize objects because they cannot perceive correct forms of the objects, although their knowledge of the objects is intact (i.e. they do not have anomia), they have apperceptive agnosia ...

  9. Chirality (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Chirality_(mathematics)

    An object that is not chiral is said to be achiral. A chiral object and its mirror image are said to be enantiomorphs. The word chirality is derived from the Greek χείρ (cheir), the hand, the most familiar chiral object; the word enantiomorph stems from the Greek ἐναντίος (enantios) 'opposite' + μορφή (morphe) 'form'.
