(美國)美國密蘇里州堪薩斯城10歲女童拉曾(Clara Lazen)在上課時發現新的分子,估計是史上年紀最小的新分子發現者。tvb now,tvbnow,bttvb+ Y! I: ]& F8 n5 T

拉曾在科學課上聽畢老師介紹分子形成後,即場以粒子模型砌出過往從未被發現的分子“tetranitratoxycarbon”,其緊密結構讓它有儲存能量的潛在特質,或能研發為炸藥。老師伯爾(Ken Boehr)見到後嘖嘖稱奇,致電老友、在加州大學任教的策勒(Robert Zoellner)求助。策勒用電腦分析拉曾的發現,認為分子構造可行。5.39.217.769 P& W H% l# v9 p( F; S5 A9 N

策勒後來在化學期刊發表論文,把新分子的特性記錄下來,讓其他學者能嘗試製造,拉曾和伯爾被列為論文共同作者。策勒表示:“我從未與一個10歲的學生合作。”tvb now,tvbnow,bttvb) c, f. D5 J k: W* l1 v2 `3 `

伯爾表示,希望拉曾的例子更以吸引更多學生對科學感興趣,拉曾則表示,她當初只是“見到這些(粒子)可以連在一塊……看起來比較好”。(香港明報)7 F& K& d1 H- N

I am kind of confused about this news. How can a fifth grader understands the characters of nitrogen, oxygen and carbon ? What criteria did she use and then combined these 3 elements together and form a complicated combination -- tetranitratoxycarbon ? Did she know when she constructed the structure of these combination, it can store energy and release energy as well ?! Well, I think the credit should be given to her teacher -- Mr. Boehr who took her structure seriously and understood the potential of it, then called Dr. Zoeliner.
