Article Evaluation
leave notes about your observations and learning from the three articles.

John Alexander Low Waddell
John Alexander Low Waddell is a Canadian Civil Engineer. The article gives a clear outline about Waddell's work. Article is written in a very neutral tone. Citation was done properly by the author. The reference works for most sources. If reader wants to learn more about Waddell, he or she can always find the right external link for further research.

Engineering Education #North America
The North America session of the engineering education is divided into Canada, United States, and Mexico. However, I do think it can be further divided into different sub-section. Currently, much of the information are squeeze into one giant paragraph or dump into a very general title such as, United States, and Mexico. The Mexico section is particular not clear. Rather focusing on the engineering education, the section is talking about the 20th Century Mexican revolution.

Time Value of Money
The article has given a very full explanation about time value of the money. Starting from the history of this concept, then calculation method and examples. Since the "time value of mone y" is very mathematical term, the article did not put any personal opinion into the writing. Links and reference are all from reliable source.

In the talk page, many people were arguing about the previous opening sentence was not clear enough. The opening sentence is the best when it is short and precise.
