” Unfortunately, there is a lot, lot, lot to be discovered still. To reconstruct evolutionary history, we have to know how the mechanisms operate in detail, and we have only the vaguest idea of how they operate at the genetic level, how genetic change relates to development and to function. . . . I am implying that what would be discovered would be not only details, but some major principles.”
接著是Australopethecus 阿法南方古猿, 就是鼎鼎大名的露西所屬的種類。美國的自然歷史博物館 American Museum of Natural History 跟台灣台中科學博物館都看的到露西的標本, 剛挖掘到的露西遺骨只有部分零碎的骨骸, 至多也只有40%找到(47 out of 207骨頭找到), 而且這40%的骨頭也都很零碎。
我記得很清楚的一個晚上, 13歲老大Gabriel 問我” Mom, are you OK with only one side left?” 我沒有想到這個孩子貼心的在乎我的感受, 我很坦然地回答他”Daddy loves me, God loves me and I love myself, son. I will be just the same” 短短的對話, 只見他開心的微笑說”As long as you are OK.”
吃飽喝足後, 家裡也清理完畢…..大家集合看電影! 我們看了這部 The Boy Who Harnessed the Wind 御風男孩。大哥之前有讀過這本小說, 一直說好看! 今天來看電影版的。
家裡有國中以上的孩子, 我也推薦這部電影 Hotel Rwanda 盧安達飯店。這兩部電影都是根據真實故事拍攝的, 我相信看完後你的孩子對非洲國家會有更多的同理心並更珍惜自己擁有的一切。我13歲的兒子看完御風男孩後跟我說”Mom, I will never take things for granted again!”
Noble Gas 裡面有King Randon, Queen Xenon, Prince Krypton, Prince Argon, Princess Neon and baby Helium. 他們是一群熱愛世界和平的王公貴族, 與世無爭…祥和的過自己的日子! (Noble Gas 的特性就是他們太和平了, 很難進行化學反應。)

Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.
舉例來說,Sodium (Na) 有11個電子, Chlorine (Cl)有17個…
Na 的 Valence Number +1, Chlorine’s Valence Number is -1.
