如果係phy個方面,只要有數學公式就得(有公式既係難過冇既好多,所以係高階好多)
就咁係圖書館借本advanced physics,advanced quantum mechanics呢d,你打開第一頁已經想喊
簡單黎講,學好課堂既先睇啦
科普書就幾時都可以睇,因為易明-.-

冇人講難同易架-.-
每個人都有唔同既能力,
我覺得數學易過中文,但有d人覺得中文易過數學,我都唔知點答你好-.-
化學既科普既text book係唔同,科普通常都唔講原理
我地阿sir岩岩講左 因為copper(II)+dichromate如果係molten state會變做啡色
咁樣你個result會唔明顯 但係你gel狀態
支野插住左的係colourless的acid
D copper(II)同dichromate會滲少少上去但又唔會好多
睇到result之外又明顯 因為個d acid係colourless

Cr2O72- ion moves to +ve electrod;
Cu2+ ion moves to -ve electrode.
the colourless solution around +ve electrode becomes orange.
P.S.
In alchemy, the symbol of copper is like the modern symbol of female.
(early represented for planet Venus, and the Goddess Venus.)
