Reflection blog post

OH YEAH! Last day of winter term 2012, time flies. I cannot believe four month has pasted, and summer is coming. HAHA~

I have to admit, I thought ALES204 is kind of useless at first, because I just about internet, blogging and tweet. No big deal, boring and easy. Later, I get the funny and knowledge behind that. I do not post personal feeling online, I believe what I think should think inside my heart, instead of telling people I know or I don’t. That was why I am not active online, even my best friend asked me to.

Now, I have Facebook, tweeter, audioboo, linkedin account and etc. Most of the accounts are used only in ALES204 class, but I keep using Facebook in my only free time. I find out information flow very fast on Facebook, text, video and pictures could be shared by other people, every friend can see what whatever I am doing. Like the page I created in Facebook, WOW, the most serious thing I have even done online. But, I like it, I never thought of Facebook can be professional. That is something new,.

Then, I did a wiki stub entry. In high school, my ENGL teacher told us we can never use Wikipedia as academic source, I never get that. I always thought back in high school, why not? Wikipedia always pump up at first choose, and all the information are there, one website included everything. Now, finally I know why. Anybody can edit Wikipedia as long as you have an account which can be created freely. I never know edit Wikipedia is that easy. Well, Wikipedia is a good tool to get a general idea, but never a good academic source.

The most useful lecture I think is the resume and cover letter one. I never done that before, it is very nice to learn the skill before I needed a job. I have learned great skill from this course, thanks to my dear professor and TAs.

Free post -- The sciences in Titanic

            I watched Titanic yesterday with my boyfriend, and we talked a lot about scientific-related life and dead in the movie, we even discussed what we would do in the same situation, the best way to stay alive when no boats are available.

            It was back in 1912, 100 years ago, the largest ship Titanic also named unsinkable sank in Atlantic Ocean in less than 3 hours. When the captain ordered the distress call, he was told only one ship response and it would take 4 hours to get there. According to a British historian – Tim Maltin, an unusual optical phenomenon explains why the Titanic received no assistance from a nearby ship. Also, atmospheric conditions in Atlantic Ocean at that night were ripe for super refraction that explains why the lookouts in Titanic could not see the iceberg.

            The Titanic was sailing from Gulf Stream, where the temperature is warmer. The air column was cooling from the bottom up on the way to New York; it created a thermal inversion, layers of cold air below layers of warmer air. Because of thermal inversion refracts light abnormally, it creates superior mirage. It makes objects appear higher than they actually are. It could confuse the vision. It happened in the Titanic, the lookouts were confused by superior mirage, they saw the sea surface higher than it actually is, and the superior mirage camouflaged the iceberg. It was too late when the Titanic lookout reported it in. When the Titanic signaled for help, but the abnormally stratified air was disrupting the signals. Also the distress rockets fired by the Titanic were too lower to see.

            Under the circumstance of no help from other ships, no enough boats for over 2100 people, and the Titanic was sinking, many people were dropped into the water, because of the crowded Titanic. Most of them were wearing life jackets, it prevented them from drowning, but it did not save them from hypothermia. The water was freezing; the people in the water would die because their bodies did not make enough of heat. According to Coco Ballantyne, a person can survive no longer than 20 minutes in 5^oC (or 41-degree F). In the movie Titanic, it was in the Atlantic Ocean, people’s hair started to freeze when they were in water. The water temperature was much lower than 5^oC, which means they have less than 20 minutes until the boats came back for them. Rose was the lucky one, she was flowing on the top of the water instead of into the water.
