  2. Halteres - Wikipedia

    en.wikipedia.org/wiki/Halteres

    The majority of insects have two pairs of wings. Flies possess only one set of lift-generating wings and one set of halteres. The order name for flies, "Diptera", literally means "two wings", but there is another order of insect which has evolved flight with only two wings: strepsipterans, or stylops; [2] they are the only other organisms that possess two wings and two halteres. [6]

  3. Common green bottle fly - Wikipedia

    en.wikipedia.org/wiki/Common_green_bottle_fly

    The presence of female flies eating or ovipositing on a carcass may attract other female flies to do the same, perhaps through chemical cues. [12] Females exhibit preference for certain oviposition conditions over others; they attempt to maximize the survival potential of their offspring by laying eggs in only the best places.

  4. Insect flight - Wikipedia

    en.wikipedia.org/wiki/Insect_flight

    The force component normal to the direction of the flow relative to the wing is called lift (L), and the force component in the opposite direction of the flow is drag (D). At the Reynolds numbers considered here, an appropriate force unit is 1/2(ρU 2 S), where ρ is the density of the fluid, S the wing area, and U the wing speed.

  5. Time perception - Wikipedia

    en.wikipedia.org/wiki/Time_perception

    The most well-known version of this illusion is known as the stopped-clock illusion, wherein a subject's first impression of the second-hand movement of an analog clock, subsequent to one's directed attention (i.e., saccade) to the clock, is the perception of a slower-than-normal second-hand movement rate (the second-hand of the clock may ...

  6. Flying and gliding animals - Wikipedia

    en.wikipedia.org/wiki/Flying_and_gliding_animals

    Fossils of flying animals tend to be confined to exceptional fossil deposits formed under highly specific circumstances, resulting in a generally poor fossil record, and a particular lack of transitional forms. Furthermore, as fossils do not preserve behavior or muscle, it can be difficult to discriminate between a poor flyer and a good glider.

  7. Why some airlines' planes fly slower than others - AOL

    Despite the occasional pilot informing passengers (proudly) of an intention to “make up time in the air,” people usually assume planes are going as fast as they safely can, like a speed limit ...

  8. Pollenia rudis - Wikipedia

    en.wikipedia.org/wiki/Pollenia_rudis

    The flies tend to frequent dry areas because of their aristae antennae. The aristae are sensitive to minute temperature and pressure changes. During the winter, adult P. rudis' have a habit of overwintering. This ritual begins when the weather starts to get cold. The flies will inhabit the old tunnels created by past insects.

    Relative velocity time dilation is where time moves slower as you move faster. The classic example of this is the twin scenario . One twin blasts off in a spaceship traveling close to the speed of ...
