EIR 3

The third lesson of EIR was on 10 Nov.  Sorry for updating this so late. But I still can remember the thing that I learnt from that lesson.

I remeber that day my friend and me were a little bit late for the EIR class because we went for the Micro-electronics talking, and it ended late. And then when I was seated, I could not remember the user name and the password, then need to ask someone.  Soon there's another guy ask tutor what the user name and password were, she said that we were not children already, these were the things that we should remember, this was one of our responsbilities. That's true!!! We should not every time wait for teacher tell us what they are, there's no excuse for this.

I was introduced another searching engine which is scholar.google.com. That was my first time using this website, and before this lesson, I didn't even know got this website exists. I found that this is a better searching website for articles and books. A lot of results are articles written by experts and university professors. And many are PDF documents. It is very convenient for us. I typed "Developments of renewable energy sources in the world" which is my topic on scholar.google.com and http://www.google.com/ respectively. Both of the two website have their pros and cons.

I have more than 14 million results on google.com and only 16 thousand for scholar.google.com. Surprisingly, I couldn't find wikipedia on the latter. Because I am so used to wikipedia. Google.com has many categories options such as image, books and news, and scholar.google.com does not have, which make me tend to like google.com more than scholar.google.com at the first time. But when I look through the results displayed on scholar.google.com, I found that many of them were in PDF form, and a lot of them are articles, which gave me many useful information on my topic.

And I also learnt how to make my search result more precisely and narrow the results, which can get rid of the unuseful information.
