„Handle so, daß die Maxime deines Willens jederzeit zugleich als Prinzip einer allgemeinen Gesetzgebung gelten könne." -- Kategorischer Imperativ, Immanuel Kant (1724-1804)
「粉身碎骨」，在這個案例上倒不至於。但是下場如何呢？其後果的首要考慮，是硬碟資料的存亡。它到底可以承受幾 G 的加速度呢？另外，「在旅程完結之際」，到底必須承受幾 G 的加速度？只用地表的重力加速度 9.8 m/sec2（1G）來計算終端速度，顯然不夠充分，因為她真的用力把電腦往前摔（稍微往前是必要的，砸到腳可不好玩）。地板，聽起來是結實的磁磚或水泥，而不是榻榻米，這一點關係至為重大，因為它決定了分母，一不小心就會讓除法的結果趨近於無窮大。不過因為還沒有太多做這種實驗的機會，經驗實在有限得很 [b]，目前難以推估。總之，「在旅程完結之際」，負加速度一定是很多、很多 G，再加 1G。
[註 1] 2001 年 911，我在學校裡的一個咖啡廳，聽到電視上的恐怖攻擊新聞快報，隨即看到當時德國總理 Gerhard Schröder 的公開談話，接著跟著大家一起默哀，不過，沒聽到有人在數 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 [c]（天啊！我是在做夢嗎!?）。印象深刻的是這一句：「今天，我們都是美國人」（Heute sind wir alle Amerikaner.）。剛剛才發現，這句話應該是社會民主黨（SPD）黨團首席 Peter Struck 講的 [2]。這句話的意涵是，自由世界的團結一致（Solidarität/solidarity）。
話說柏林圍牆剛築起的冷戰時期，西德總理是康拉德．艾德諾（Konrad Adenaur, 1949-09-15 to 1963-10-16）。1963 年 6 月 26 日，美國總統約翰．甘迺迪（John Fitzgerald Kennedy, 1917-05-29 to 1963-11-22）來到西柏林，演講時準備了小抄，以德語發音講了一句膾炙人口的名言「我是柏林人」（Ich bin ein Berliner）[3]：
Two thousand years ago, the proudest boast was civis romanus sum ["I am a Roman citizen"]. Today, in the world of freedom, the proudest boast is "Ich bin ein Berliner!"... All free men, wherever they may live, are citizens of Berlin, and therefore, as a free man, I take pride in the words "Ich bin ein Berliner!"
他講這句話的意涵，也在於「自由世界」的團結與擁護。他以新約聖經使徒行傳 [4] 裡保羅的話做為引言。保羅當時四處傳教，招致「禁閉」與「凌虐」，他以「我是羅馬公民」（拉丁文：civis romanus sum）的身分，來維護涉己的法律程序正義，以保護自己的權利與安全。
[註 2] 其實，"Ich bin ein Berliner." 聽起來有點詼諧，因為我吃過 "Berliner"。那是一種圓圓的夾心麵包，上面通常灑了白色的糖粉。最好的辦法還是按這裡，看看 Google 給你的影像。到柏林旅遊的人，別忘了買一個來吃吃看。除此之外，也要記得嚐嚐路邊的 CPM（Currywurst-Pommes-Mayo），也就是切塊的德國香腸淋上辣醬跟咖哩粉，加上薯條配美乃滋。在台灣，很難吃到附加美乃滋的薯條，後來我都乾脆用麥當勞的蛋捲冰淇淋代替美乃滋，這樣起碼在視覺上得到一點補償…請看看這裡的圖片吧。Hmmm... 就快受不了∼
I am proud to come to this city as the guest of your distinguished Mayor, who has symbolized throughout the world the fighting spirit of West Berlin. And I am proud to visit the Federal Republic with your distinguished Chancellor who for so many years has committed Germany to democracy and freedom and progress, and to come here in the company of my fellow American, General Clay, who has been in this city during its great moments of crisis and will come again if ever needed.
Two thousand years ago the proudest boast was "civis Romanus sum." Today, in the world of freedom, the proudest boast is "Ich bin ein Berliner."
I appreciate my interpreter translating my German!
There are many people in the world who really don't understand, or say they don't, what is the great issue between the free world and the Communist world. Let them come to Berlin. There are some who say that communism is the wave of the future. Let them come to Berlin. And there are some who say in Europe and elsewhere we can work with the Communists. Let them come to Berlin. And there are even a few who say that it is true that communism is an evil system, but it permits us to make economic progress. Lass' sie nach Berlin kommen. Let them come to Berlin.
Freedom has many difficulties and democracy is not perfect, but we have never had to put a wall up to keep our people in, to prevent them from leaving us. I want to say, on behalf of my countrymen, who live many miles away on the other side of the Atlantic, who are far distant from you, that they take the greatest pride that they have been able to share with you, even from a distance, the story of the last 18 years. I know of no town, no city, that has been besieged for 18 years that still lives with the vitality and the force, and the hope and the determination of the city of West Berlin. While the wall is the most obvious and vivid demonstration of the failures of the Communist system, for all the world to see, we take no satisfaction in it, for it is, as your Mayor has said, an offense not only against history but an offense against humanity, separating families, dividing husbands and wives and brothers and sisters, and dividing a people who wish to be joined together.
What is true of this city is true of Germany--real, lasting peace in Europe can never be assured as long as one German out of four is denied the elementary right of free men, and that is to make a free choice. In 18 years of peace and good faith, this generation of Germans has earned the right to be free, including the right to unite their families and their nation in lasting peace, with good will to all people. You live in a defended island of freedom, but your life is part of the main. So let me ask you as I close, to lift your eyes beyond the dangers of today, to the hopes of tomorrow, beyond the freedom merely of this city of Berlin, or your country of Germany, to the advance of freedom everywhere, beyond the wall to the day of peace with justice, beyond yourselves and ourselves to all mankind.
Freedom is indivisible, and when one man is enslaved, all are not free. When all are free, then we can look forward to that day when this city will be joined as one and this country and this great Continent of Europe in a peaceful and hopeful globe. When that day finally comes, as it will, the people of West Berlin can take sober satisfaction in the fact that they were in the front lines for almost two decades.
All free men, wherever they may live, are citizens of Berlin, and, therefore, as a free man, I take pride in the words "Ich bin ein Berliner."
