A left-handed bowler competes on the opposite side of the lane from the right-handed bowler and therefore deals with less breakdown of the original oil placement. This means left-handed bowlers have to adjust their shot less frequently than right-handed bowlers in team events or qualifying rounds where there are possibly 4-10 people per set of ...
Over 90% [1] of gastropod species have shells in which the direction of the coil is dextral (right-handed). A small minority of species and genera have shells in which the coils are almost always sinistral (left-handed). Very few species show an even mixture of dextral and sinistral individuals (for example, Amphidromus perversus). [2]
Historical one-handed versions have blades varying from 45 to 80 cm (18 to 31 in) in length. The weight of an average sword of 70 cm (28 in) blade-length would weigh about 700 to 900 g (1.5 to 2.0 lb). [20] There are also larger two-handed versions used by ancient and medieval armies and for training by many styles of Chinese martial arts.
Cross-dominance, also known as mixed-handedness, hand confusion, or mixed dominance, is a motor skill manifestation in which a person favors one hand for some tasks and the other hand for others, or a hand and the contralateral leg. For example, a cross-dominant person might write with the left hand and do everything else with the right one, or ...
Jan-Michael Gambill is the opposite case of Kulikovskaya, since he played with a two-handed forehand and backhand, although he served with his right hand. Other famous examples of a two-handed forehand are Fabrice Santoro and Monica Seles .
A type of military backsword – a British 1796 heavy cavalry sword purchased by Sweden in 1808. A backsword is a type of sword characterised by having a single-edged blade and a hilt with a single-handed grip. [1] It is so called because the triangular cross section gives a flat back edge opposite the cutting edge. [2]
In biology, 19 of the 20 natural amino acids are homochiral, being L-chiral (left-handed), while sugars are D-chiral (right-handed). [1] Homochirality can also refer to enantiopure substances in which all the constituents are the same enantiomer (a right-handed or left-handed version of an atom or molecule), but some sources discourage this use ...
For example, the electric field vectors of left-handed or right-handed circularly polarized waves form helices of opposite handedness in space. Circularly polarized waves of opposite handedness propagate through chiral media at different speeds (circular birefringence) and with different losses (circular dichroism). Both phenomena are jointly ...
