3. Arrow pushing - Wikipedia

   en.wikipedia.org/wiki/Arrow_pushing

   Arrow pushing or electron pushing is a technique used to describe the progression of organic chemistry reaction mechanisms. [1] It was first developed by Sir Robert Robinson.In using arrow pushing, "curved arrows" or "curly arrows" are drawn on the structural formulae of reactants in a chemical equation to show the reaction mechanism.

4. Arrow (symbol) - Wikipedia

   en.wikipedia.org/wiki/Arrow_(symbol)

   Upward arrows are often used to indicate an increase in a numerical value, and downward arrows indicate a decrease. In mathematical logic, a right-facing arrow indicates material conditional, and a left-right (bidirectional) arrow indicates if and only if, an upwards arrow indicates the NAND operator (negation of conjunction), an downwards arrow indicates the NOR operator (negation of ...

   The Arrows block contains eight emoji: U+2194–U+2199 and U+21A9–U+21AA. [3] [4]The block has sixteen standardized variants defined to specify emoji-style (U+FE0F VS16) or text presentation (U+FE0E VS15) for the eight emoji, all of which default to a text presentation.

9. Recurve bow - Wikipedia

   en.wikipedia.org/wiki/Recurve_bow

   In archery, a recurve bow is one of the main shapes a bow can take, with limbs that curve away from the archer when unstrung. A recurve bow stores more energy and delivers energy more efficiently than the equivalent straight-limbed bow, giving a greater amount of energy and speed to the arrow.
