（安：會唔會可以降低啲要求：唔需要”非常有料到”，而係”somehow 有料到”？）
所以我就話有另一種可能性。
.
一係就 intellectual level 差唔多。
一係就 intellectlly compatible。
Compatible 嘅話，佢可以 level 低我好多。
例如啲機械人卡通，有隻大機械人，唔識飛嘅。
但係有一隻細機械人，可以變成一對翼，同隻大機械人合體。
咁大機械人就可以飛喇。
.
大機械本身就唔識飛，而果隻細機械人飛嚟都無用。
但係兩隻合體，就變成好勁嘅野。
.
（Me：你想唔想像到我嘅意思呀？呢個比喻 O 唔 OK 呀？駛唔駛諗個再勁啲咖？
安：唔駛。呢個比喻最得意之處係，”細嘅機械人飛來都無乜用”。
Me：OK 喎… 我講嗰陣，都諗唔到呢樣野…）

However, the path integral formulation is also extremely important in direct application to quantum field theory, in which the “paths” or histories being considered are not the motions of a single particle, but the possible time evolutions of a field over all space.
Much of the formal study of QFT is devoted to the properties of the resulting functional integral, and much effort (not yet entirely successful) has been made toward making these functional integrals mathematically precise.
