The QWERTY layout has more than 3,000 words that are typed on the left hand alone and about 300 words that are typed on the right hand alone (the aforementioned word "minimum" is a right-hand-only word). In contrast, with the Dvorak layout, only a few words are typed using only the left hand and even fewer use the right hand alone.
Bias against left-handed people is bias or design that is usually unfavorable against people who are left-handed. Handwriting is one of the biggest sources of disadvantage for left-handed people, other than for those forced to work with certain machinery. About 90 percent of the world's population is right-handed, [1] and many common articles ...
Chirality for a Dirac fermion ψ is defined through the operator γ 5, which has eigenvalues ±1; the eigenvalue's sign is equal to the particle's chirality: +1 for right-handed, −1 for left-handed. Any Dirac field can thus be projected into its left- or right-handed component by acting with the projection operators 1 / 2 (1 − γ 5) or 1 / ...
The left hand is a non-superposable mirror image of the right hand; no matter how the two hands are oriented, it is impossible for all the major features of both hands to coincide across all axes. This difference in symmetry becomes obvious if someone attempts to shake the right hand of a person using their left hand, or if a left-handed glove ...
Conventionally, it is given by the right-hand rule, where one simply points the forefinger of the right hand in the direction of a and the middle finger in the direction of b. Then, the vector n is coming out of the thumb (see the adjacent picture). Using this rule implies that the cross product is anti-commutative; that is, b × a = −(a × b).
10. The manual alphabet can be used on either hand, normally the signer's dominant hand – that is, the right hand for right-handers, the left hand for left-handers. [1] Most frequently, the manual alphabet is signed just below the dominant shoulder of the signer. When used within other signs or in a context in which this is not plausible ...
In English and most European languages where words are read left-to-right, text is usually aligned "flush left", meaning that the text of a paragraph is aligned on the left-hand side with the right-hand side ragged. This is the default style of text alignment on the World Wide Web for left-to-right text. Quotations are often indented. Flush ...
The digit ratio is the ratio taken of the lengths of different digits or fingers on a hand. In modern sciences, the 2D:4D ratio has become the most commonly studied digit ratio and is calculated by dividing the length of the index finger of a given hand by the length of the ring finger of the same hand. Some studies claimed that males have a ...
