analogy

Examples of analogy in the following topics:

• Analogies

  • Choose a suitable analogy that the audience will be able to connect with and relate to.
  • Keep analogies short and simple.
  • Extreme analogies can weaken rather than strengthen an argument.
  • Use analogies as a springboard rather than as the main focus of the presentation.
  • Define analogies and how they can be used as a linguistic tool in public speaking

• Distinguishing between Similar Traits

  • These are called analogous structures .
  • Similar traits can be either homologous or analogous.
  • These structures are not analogous.
  • The wings of a butterfly and the wings of a bird are analogous, but not homologous.
  • Some structures are both analogous and homologous: the wings of a bird and the wings of a bat are both homologous and analogous.

• Power

  • The circuit is analogous to the wheel of a car driven over a corrugated road, as seen in .
  • The regularly spaced bumps in the road are analogous to the voltage source, driving the wheel up and down.
  • The shock absorber is analogous to the resistance damping and limiting the amplitude of the oscillation.
  • The forced but damped motion of the wheel on the car spring is analogous to an RLC series AC circuit.
  • The shock absorber damps the motion and dissipates energy, analogous to the resistance in an RLC circuit.

• Color Schemes

  • Analogous colors are groups of colors that are adjacent to each other on the color wheel, with one being the dominant color (typically a primary or secondary color) and two on either side complementing (most often tertiary colors).
  • Red, red-orange, and orange are examples of analogous colors.
  • The term analogous refers to the having analogy, or corresponding to something in particular.
  • An analogous color scheme creates a rich, monochromatic look in an artwork.

• Homologous Structures

  • Bat wings and bird wings evolved independently and are considered analogous structures.
  • In the above example, the bird and bat wings are analogous as wings, but homologous as forelimbs because the organ served as a forearm (not a wing) in the last common ancestor of tetrapods.
  • Although analogous characteristics are superficially similar, they are not homologous because they are phylogenetically independent.
  • The wings of a maple seed and the wings of an albatross are analogous but not homologous (they both allow the organism to travel on the wind, but they didn't both develop from the same structure).
  • The wings of pterosaurs (1), bats (2), and birds (3) are analogous as wings, but homologous as forelimbs.

• Rotational Inertia

  • There are, in fact, precise rotational analogs to both force and mass.
  • This equation is the rotational analog of Newton's second law (F=ma), where torque is analogous to force, angular acceleration is analogous to translational acceleration, and mr2 is analogous to mass (or inertia).

• Introduction to comparing two relations for the same set of actors

  • This kind of question is analogous to the test for the difference between means in paired or repeated-measures attribute analysis.
  • This kind of question is analogous to the correlation between the scores on two variables in attribute analysis.
  • This kind of question is analogous to the regression of one variable on another in attribute analysis.

• Grob Fragmentation

  • Here a simple nucleophilic fragmentation at M is converted to an ethylagous analog by the insertion of a two carbon (ethyl) segment between the reacting moieties.
  • The non-ethylagous analog for the reaction is drawn in the gray-shaded box.

• Addition Reactions Involving Other Cyclic Onium Intermediates

  • Indeed, a cyclic sulfonium ion intermediate analogous to the bromonium ion is believed to best represent this intermediate (see drawing below).
  • These characteristics are attributed to a mercurinium ion intermediate, analogous to the bromonium ion discussed above.

• Convergent Evolution

  • Traits arising through convergent evolution are analogous structures, in contrast to homologous structures, which have a common origin, but not necessarily similar function.
  • The British anatomist Richard Owen was the first scientist to recognize the fundamental difference between analogies and homologies.
  • Bat and pterosaur wings are an example of analogous structures, while the bat wing is homologous to human and other mammal forearms, sharing an ancestral state despite serving different functions.
