淬炼智慧的火花

    ①瞬息爆发的闪电,可以照亮静谧的夜空;突然萌生的灵感,激发人们创作不朽篇章。在科学研究领域,偶然迸发的智慧火花,往往能催生意想不到的创新。

    ②回溯科技史,那些曾经点亮文明星空的光亮,至今令人难忘。阿基米德发现浴盆里的水因自己坐入而外溢,顿悟测量王冠中黄金成分的办法,提出浮力定律;瓦特看到壶盖被水蒸气推开,脑海中闪过电光火石般的灵感,继而开创了蒸汽时代。不少真理的探索、创造的诞生,看上去竟然得益于偶然事件。那么,这是否意味着,想要在科学上有所作为,只需等待偶然迸射的智慧火花呢?

    ③其实不然。智慧之火花,恰恰是长期砥砺实践的结晶。马克思曾对此作过一个比喻,“最好是把真理比作燧石——它受到的敲打越厉害,发射出的光辉就越灿烂”以牛顿发现万有引力定律为例,以往人们总是把它和苹果落地的偶然性联系在一起。其实在这之前,伽利略、开普勒就分别在物体运动和天体运动领域研究出了斐然成果。“如果说我看得更远一点的话,是因为我站在巨人的肩膀上。”牛顿继承前人成就,悉心钻研力学与天文学,对物体运动规律的理解日渐深刻。正是在这种背景下,苹果落地的现象才会在他的心中激荡起涟漪。_______________________________。

    ④伽伐尼发现电流的故事,令人深思。一次,他无意中把一只解剖的青蛙放在静电机旁的桌上,一位助手用解剖刀触及蛙腿的神经时,发现蛙腿突然收缩,另一位助手则发现静电机突然放出火花。面对奇特未知的现象,助手们也只是感到惊讶而已,但博学多才的伽伐尼却被其中的奥妙紧紧攫住。从此他锲而不舍地钻研,终于为电流和电池的研究开辟了道路。现实中,从火花到燃烧是需要一定条件的。如果自身不是可燃体,即便四周火花飞溅,也无法持续释放光与热。智慧的火花来之不易,只有及时为它添火加柴,才能点燃梦想和希望,照亮探索科学真谛的道路。

    ⑤“悟已往之不谏,知来者之可追”。点燃智慧的火花,还应保持敏锐,葆有时不我待的忧患意识。正因此,面对稍纵即逝的灵思妙想,不少人的办法是“先捉住、再消化”。诗人马雅可夫斯基,总是随身带着小本子和笔,随时为作诗储备矿藏;发明家爱迪生,经常记录新鲜题目和见解,然后再回过头来翻阅、思考。苏东坡诗云:“作诗火急追亡逋,清景一失后难摹。”捕捉智慧的火花并非易事,这离不开枕戈待旦的警觉和锲而不舍的精神。

    ⑥勺水渐积成沧海,拳石频移作泰山。从经年累月的潜心钻研、电光火石的灵感乍现到熊熊燃烧的智慧火焰,人类取得的累累硕果背后,都历经了一番煅烧、冶炼的过程。笃信实践出真知、勤奋出灵感,积蓄沉潜的韧劲儿,智慧的火花必能在我们身边频频闪耀。

【注释】淬(cuì)炼:指反复经受考验,磨练。工艺中,淬炼即把加热至红热的金属(如钢)立刻浸入冷水,增加物体的强度和硬度,减小物体的韧性。

作诗火急追亡逋,清景一失后难摹:(我)急忙提笔写下了这首诗歌,恐怕稍有延迟,那清丽的景色便从脑海中消失,再也难以描摹。

    The wedding tradition of “something old, something new, something borrowed and something blue” has been around for hundreds of years. The tradition of carrying or wearing one of each item is said to bring luck and fortune to the newly married couple. Have you ever stopped to think what the saying really means? What is its origin and what does each item represent?

    The original saying dates back to the Victoria times and states, “something old, something new, something borrowed, something blue and a silver sixpence in your shoe.”

    Something old   A bride may wear or carry something old to represent her continued ties to her family and her old life. Many brides wear a piece of family jewelry as their old item. Some brides wear the wedding dress worn by their mother or grandmother. In many cases, something old may also be something borrowed.

    Something new   Wearing something new is supposed to represent success and hope in the bride's new life and in her marriage. If the bride purchased her wedding dress new, it may represent her new item, but any item that is new may be used. Something “new” is usually the easiest kind to fill.

    Something borrowed   The borrowed item should be something borrowed from a friend that is happily married. It is said that their happiness will rub off on you and bring lasting happiness to your marriage. Some brides borrow an item of clothing, a piece of jewelry, a handkerchief or perhaps a beaded(带珠子的) purse.

    Something blue Wearing something blue dates back to ancient times when a blue wedding dress was worn to represent purity, fidelity and love.

    Silver sixpence   Placing a silver sixpence in the bride's left shoe is said to be a symbol of wealth. This not only refers to financial wealth, but also a wealth of happiness and joy throughout her married life. Since most brides probably don't even know what a sixpence is, this part of the tradition is not used very often in modern times. However, if a bride would like to include it in her wedding, she can purchase a silver sixpence from many companies that sell bridal supplies such as garters(袜带) and invitations.
