It was in November on a train from Helsingor to Copenhagen that a friend told me I should definitely visit Niels Bohr Institute in Copenhagen upon knowing that I will stay in CERN for 1 month. Though I have studied his theories of complementarity in high school, it never occurred to me that he is a Danish and works in Copenhagen. So it became a great preliminary thing to do as Copenhagen is my stop before Geneva.
去年十一月在由丹麥赫辛格往哥本哈根的火車上，一位朋友在聽到我要到CERN駐村後，提到我應該到哥本哈根的波耳實驗室拜訪。雖然高中的時候有讀過他的互補原理（見互補原理），卻從來不記得他是丹麥人。因為剛好要到丹麥開會，就順便在駐村之前拜訪了波耳實驗室。
The librarian Ms Pors showed me around of how the building is, and how the interactions of the scientists (which were the names occupied my whole physics textbook when I was 16) were like. There was Einstein, Kramer, Heisenberg, Pauli, etc.
波耳實驗室現在有部分被保存為博物館，其他部部分仍然保持前端科學研究，屬於哥本哈根大學的一部份。接待我的圖書館員Pors小姐帶我從過去的歷史講著那些有名的（課本上一定會看到的）物理科學家像是波耳、愛因斯坦、海森堡等人是如何在二次世界大戰前後在這個建築物內討論物理。
The best part of it was seeing Bohr chose the Yin-Yang sign as his code of arms — as the interpretation of wave-particle duality. It was also a pleasant surprise that he not only does physics, a huge part of Bohr’s writing were philosophy, and sometimes about Biology. The almighty librarian Ms. Pors said however, Bohr never directly mention the influence of eastern philosophy on his research. 😉
最有趣的部分莫過於Pors小姐說當波耳被丹麥皇家頒給榮譽的時候，他選擇了太極的符號作為他的家徽，因為那是詮釋他在物理上的發現最好的符號。而他不僅僅是個物理學家，也曾寫過許多哲學著作，有些時候甚至從物理的角度去思考生物的本質。不過Pors小姐表示波耳本人並沒有提到東方哲學對於他是否有什麼思想上的影響。
Another interesting thing is what Abraham Pais mentioned the discussion where Bohr had this moment of realising it should be “uniformity” instead of “harmony”. (See book Niels Bohr’s Times In Physics, Philosophy and Polity).
另外就是波耳的書寫…
My biggest impression at the Bohr Institute was how he advocate for the open science – that the world must all aware of where we are at for our technology and scientific research, and that it should not be influence by political powers to conceal research results. In a way, this believe also contributes to the creation of CERN.
而印象最深刻的部分為波耳所稟持著科學必須被開放、整個世界都有權利也必須知道人類科學研究的進展而不應該受政治所影響（如美國與俄國冷戰、第二次世界大戰的原子彈研發）等等，而這也是CERN當初創立的宗旨之一。
And the original drawings Ms. Pors have accidentally step upon when showing me the drawing room. The early designs of cloud chambers and magnets.
還不小心的在抽屜裡找到了當年的雲室與磁鐵設計圖。
There was also his discussion of the uncertainty of time with Einstein. (See Bohr-Einstein Debate)
還有波耳與愛因斯坦對於時間也具有不確定性的辯論。
This visit left a lot of fruitful thoughts that would need to explore later this month. How do physicists debate, approach the reality, and how do they construct?
這次拜訪讓我對於科學家之間如何辯證、如何接近「reality」還有如何建構各種的理論感到越來越好奇。
