This is just a report of a seminar.
By exploring truly modern aspects of quantum mechanics in the undergraduate laboratory students can understand Quantum Mechanics, which may be hard if students only think about those abstract theories. “Exploring Fundamentals of Quantum Mechanics in the Undergraduate Laboratory” was a lecture, which was presented by Professor Mark Beck. Before the lecture students learned quantum mechanics from a little of history to wave-particle Duality experimental phenomena, which was a huge step to cross. During the learning process, the heavy mathematical analysis usually bothered students a lot. Maybe the teaching materials or methods need to be changed. A suitable textbook will lead students to a new concept of learning quantum mechanics.
There were five presented experiments in this lecture. The purpose is to provide some visible results for students to understand comprehensive quantum mechanics. The first one was spontaneous parametric down conversion. The second one was to “prove” Photons exist. The third one was single-photon interference. The fourth one was quantum state measurement. The fifth one was to test of local realism. The first laboratory section included optical experiments, which provided one photon converted into two. Because of energy conservation and momentum conservation, the photons were produced at the same time. Since the optical experiment was visible, students could get clear images of the results, which helped them to comprehend the difficult quantum mechanics theories.

Winter Storm Warning in Northwest Oregon
Since winter storm is coming to Northwest Oregon, our campus closes at 2pm this afternoon.
When I was in Taiwan, I only got " typhoon day off". Now I got " Winter Storm day off", and most of students head home as soon as possible.

How are you
I have a chance to learn different language from my friend. Therefore, I want to take a note before I forget it.
Sa-lon = hello / hi
Ke Va a hal = how are you?

My work in our lab
The work for me to do in the lab is fabrication of fiber-based near-field optical probes, which are used for implementing high resolution Raman spectroscopy.
In addition to the fabrication process includes chemical etching and metal coating under vacuum conditions. We aim to measure directly the nanometer-sized amplitude of the NSOM probe when the probe is mounted on a Tuning Fork. We plan to use the "razor blade" method. By moving the razor blade across the image an intensity profile is recorded. This method allows simultaneous measurement of both the tuning fork output signal and the ac component of the optical intensity. Alternative we could use an interferometer set up.
A particular application of this work is to monitor, via nano-Raman, the eventual liquid-solid phase transition that mesoscopic fluid films undergo when subjected to confinement (between the NSOM probe and a solid substrate.

(HW) Report of Seminar-How long will LCDs remain the dominant display technology?
This is brief summary of my report about an overview of LCD technology and competing approaches to flat panel displays.
As technology improves, the displays of electric devices are changing to thin and light monitors. Therefore Liquid Crystal Displays are replacing the big and heavy CRT monitors. The structure of LCD is composed of two sheets of specially treated glass such as Indium Tin Oxide (ITO), contains a liquid crystal solution, and a pair of polarizers.
Type of LCD:

Bye 2013 Hello 2014
To begin with 2013 I flight back Taiwan to visit my family, and we had good time there.
Time fly, it's already one year nearly.
At the end of this year I got my Current Term GPA~ 3.83, and my professor took me out for dinner to celebrate.

Christmas gift
It's time to exchange Christmas Gifts, and you can see last minutes gift sale in different stores.
When I saw the word on the t-shirt, I can't control my self to stop laughing, but I didn't buy it.

Summary of science lecture
This was a summary of science lecture, which took place in the First Congregational Church.
(這個科學講座是因為學校有贊助,所以我們可以自由索票然後再到學校附近的教堂去聽演講。)
The speaker of " A Future of Radical Abundance : Nanotechnology Transforming Material Civilization" was Eric Drexler.
