- 1向量(數學);病媒(生物)
A vector is something that has both a size and a direction — like "5 kilometers, going north." Scientists and math teachers use it to show forces, movement, or wind. In biology, a vector is also an animal (often an insect) that carries a disease from one living thing to another — for example, a mosquito is a vector for malaria.
From the word’s history
Learned borrowing from Latin vector 'carrier', from vehō 'to carry', the root of vehicle.
借自拉丁文 vector「攜帶者」,來自 vehō「運送」。
組成From Latin "vector," meaning "one who carries" — related to the word "vehicle."
同家族的字
- vehiclecomes from the same Latin root meaning "to carry"
