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 ...
Flies with impaired mushroom bodies cannot form an odour association [31] and cockroaches with impaired mushroom bodies cannot make use of spatial information to form memories about locations. [32] Electrophysiological underpinnings of the cognition in different parts of the insect brain can be studied by various techniques including in vivo ...
where Δt is the time interval between two co-local events (i.e. happening at the same place) for an observer in some inertial frame (e.g. ticks on their clock), known as the proper time, Δt′ is the time interval between those same events, as measured by another observer, inertially moving with velocity v with respect to the former observer ...
Diptera is a large order containing more than 150,000 species including horse-flies, [a] crane flies, hoverflies, mosquitoes and others. Flies have a mobile head, with a pair of large compound eyes , and mouthparts designed for piercing and sucking (mosquitoes, black flies and robber flies), or for lapping and sucking in the other groups.
The common green bottle fly (Lucilia sericata) is a blowfly found in most areas of the world and is the most well-known of the numerous green bottle fly species. Its body is 10–14 mm (0.39–0.55 in) in length – slightly larger than a house fly – and has brilliant
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 ...

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.
