Getting Back to Blogging

Looking back from all kinds of the step here — piling up the stories little by little about the Ph.D. student life here from 2012 to 2014, it is definitely interesting.

Another four years later — I am planning to get back to blogging.

Hello my dear cutie!

Repairing Iphone 4S Power Button yourself - DIY修理4S電源按鍵

I am writing down what I have prepared for this project.
簡單的紀錄一下修理的要點。

Issue: the power button could not be pressed anymore

狀況：4S電源按鍵失效（不能按）

Reason: the switch inside fatigueed.
原因：內部按鈕開關（關鍵）疲勞失效

The Pacific Rim on deep ocean power science workshop 2/23-2/26/14

夏威夷會議是一個很特別的合作型會議。 不僅只是讓環太平洋的國家如台灣日本美國夏威夷一同合作之外，跨領域的攜手合作就如同我夢寐以求般的理想，包涵了物理、燃燒、和海洋深層科學研究

Electric Field Flames Reveal in Schlieren Imaging Technique 流場還原成像技

你有觀察過燭火周圍的海市蜃樓嗎？我們要如何還原火焰流場的真相呢？Schlieren 成像技術已經有數個世紀的歷史了，這個方式可以很神奇的讓科學家真正的把原本肉眼看不到的流場變成看得到。下面這張schlieren圖，上面有個螺絲放在板子上，這是要告訴我們這張圖片成像的聚焦處是幾經微調到成像最清晰的地方，連螺牙都清晰可見。

Have you ever observed that the gases around a candle looks different? How does a regular flame jet reveals its truth of flow field? Schlieren  technique has been know for centuries for  scientists understand the invisible flow field. This technique is able to amazingly image flow field become visualize. The following is a schlieren image with a screw on top of the plate which tells you the image is accurate focused at the desired testing zone.

  

Behind the onion - Scientific X-ray Vision 科學超人眼

  On the left-hand side, it is a picture as everyone is able to take on the side-view of a flame. This image is as the same as what we normally taking in our daily life - we are imaging living three dimensional objects onto a screen. The screen gathers all the information of all the objects projected as a two dimensional picture. Is it possible to see what's in the middle between objects on the picture? How can we get to see only one slice located at the center plane of the flame? Superman gets his talent X-ray eye to see this world but we don't.

  

  左手邊這張照片，是一張你我都會拍攝的火焰側面玉照。他的拍攝方式如同我們一般相機拍照稀鬆平常，垂手可得 —— 把想要拍攝的三維空間成像投影在相機裡的屏幕上。這張屏幕把這個角度的所有投射物體變成一張二維空間的照片。我們有可能可以看到照片物體和物體香疊的中間有什麼嗎？有什麼辦法我們可以只看到照片中間一個平面（剖面）的火焰的樣子？超人有他天生的透視眼可以穿透物體看到一切，但是我們沒有這個技能。

  The right-hand side picture is a mathematically resolved image located right in the middle of the flame. I am  expressing my admire to those scientists open up all of mysteries of physical phenomenon by mathematics. They are hard thinkers. They are one kind of philosopher trying to make the life having more sense.

右手邊這張照片是一個數學方法解出來的圖片，他就是火焰正中間一個由上到下一個平面的照片。科學家們不遺餘力的努力挖掘不同的方法來找尋這個世界的奧秘。我非常的佩服他們。他們是思想家，也是一種哲學家，他們努力的讓這個世界更有意義。
