A police officer in Taiwan wears a white motorcycle helmet in conjunction with a high-visibility vest. According to a 2004 study, the wearing of reflective or fluorescent clothing correlated with a 37 percent lower risk of a rider sustaining a crash-related injury; likewise, white helmets demonstrated a 24 percent reduction.
The term visible difference is a more neutral, encompassing descriptor for any physical characteristic that sets an individual apart from what is generally considered the societal norm. [4] This could be due to congenital conditions, acquired conditions, diseases, or even personal choices like tattoos or piercings.
In 2016, the International Astronomical Union (IAU) organized a Working Group on Star Names (WGSN) [2] to catalog and standardize proper names for stars. The WGSN's first bulletin, dated July 2016, [3] included a table of 125 stars comprising the first two batches of names approved by the WGSN (on 30 June and 20 July 2016) together with names of stars adopted by the IAU Executive Committee ...
Their bold, creative, charismatic personalities often make them more visible. Onlookers admire their natural, dramatic, humorous presence. After all, they're ruled by the Sun.
A visible ring of feathers around a bird's eye; the eye-ring is often paler than the surrounding feathers. By contrast, an orbital ring is bare skin ringing the eye. In some species, such as little ringed plover, the orbital ring may be quite conspicuous. [97] eyestripe Also, eye line / eyeline.
Eidetic memory (/ aɪ ˈ d ɛ t ɪ k / eye-DET-ik), also known as photographic memory and total recall, is the ability to recall an image from memory with high precision—at least for a brief period of time—after seeing it only once [1] and without using a mnemonic device.
The visible range of light is defined by what is readily perceptible to humans, though the visual perception of non-humans often extends beyond the visual spectrum. The resulting perception is also known as vision , sight , or eyesight (adjectives visual , optical , and ocular , respectively).
Daily experiences of matter and the Universe are characterized by very low energy. For example, the photon energy of visible light is about 1.8 to 3.2 eV. Similarly, the bond-dissociation energy of a carbon-carbon bond is about 3.6 eV. This is the energy scale manifesting at the macroscopic level, such as in chemical reactions
