vertex
英 ['v??teks]
美 ['v?t?ks]
- n. 頂點(diǎn)；[昆] 頭頂；[天] 天頂
助記提示
1、vert- + -ex.
2、字面含義：that which turns, the turning point. => whirling column, whirlpool. => highest point, the point opposite the base in geometry.
3、其原始含義或者說最初含義為：whirling column, whirlpool. 也就是：漩渦，漩渦所涌出的漩渦柱；想象一下升起的漩渦柱頂端的頂點(diǎn)。再想象一下咱們物理學(xué)中的“鐘擺模型”，其自由轉(zhuǎn)動(dòng)只會(huì)低于其中心的轉(zhuǎn)動(dòng)點(diǎn)。
4. 轉(zhuǎn)折點(diǎn)---頂點(diǎn)就是發(fā)生轉(zhuǎn)折的點(diǎn)。
中文詞源
vertex 頂點(diǎn)來自拉丁語vertex,頂點(diǎn)，最高點(diǎn)，來自vert-,轉(zhuǎn)，詞源同convert,versus,-ax,最高級(jí)后綴，詞源同apex,next, approximate.
