今日去左圖書館預約左

入面有冇得學wave既基本野?

我答埋呢個算啦
呢本書既主指唔係集中係wave,唔會講wave既basic concept
其實wave只係好少既一部分黎-.-

o....................................
但係wave
可能d科普書作者以為d人一定識
所以唔會特別講
學校又末教到
咁我咪想學下wave既野先

唉 無人討論下 虛數?
我覺得好神秘

虛數其實根本唔存在,係數學上既一個假設@@

我覺得 好似以前咁 d人覺得開方2 都係唔存在,慢慢就存在左
同埋 數學家本身都唔承認 虛數 e家都承認左
可能過多200年 物理知識 又多d 咁虛數 就明洗

仲有咩虛數時間

-終場ソ使者-

For my own comprehension, "虛數時間" would never occur in the physics world.
For example, if you want accelerating a particle as speed of light(even faster than light), you will find that it must not happen because of the following mathematical expression, that
            (where   )
(I had commented in a certain post.)
There is an equation of relating time in special theory of relativity that
,
you can imagine that v must not be equal or greater than c,
in equal case, t becomes infinity; while "虛數時間" will occur when v>c.
But, you know that there is no such a complex solution in physics, it's only foy mathematics, is a mathematical joke!!!

咩係v 咩係c
