Arguing with an Engineer

Arguing with an engineer is a lot like wrestling in the mud with a pig. After a few hours, you realize that he likes it.

Definition of Engineering Definition of Engineering

According to ABET, Engineering is:

“The profession in which a knowledge of the mathematical and natural sciences gained by study, experience, and practice is applied with judgment

to develop ways to utilize, economically, the material forces of nature for the benefit of mankind.

Engineering and Science Engineering and Science

“Both the engineer and scientist are thoroughly educated in the mathematical and natural sciences, but the scientist primarily uses this knowledge to

acquire new knowledge, whereas the engineer applies this knowledge to design and develop usable devices, structures and processes. In order words.

The scientist seeks to know, the engineer aims to do”.

• Art and Engineering Drawings!

• Similarities– Starts with a blank

page– Visualization– Ideas transmitted

from mind to paper

• Differences– Usually a solution

to a ‘problem’– More logical– Design is actually

created

Joke for the Day Joke for the Day

Engineers and LawyersThere was once an engineer who found a magic lamp. When he rubbed it, a genie jumped out and said to him, "You have three wishes. But there is a catch - this wish system of mine was designed

by a lawyer, so whatever you wish for every lawyer in the world will get double of!"The engineer replied, "That's no problem, I can live with that." He then said, "For my first wish, I

wish I had a Ferarri." "OK", said the genie, and a Ferarri appeared in front of the engineer. "But remember, every lawyer

in the world now has 2 Ferarris," the genie told the engineer.The engineer remained unperturbed and said, "For my second wish, I wish for a million bucks." So

a million bucks appeared in front of the engineer and the genie said, "remember, every lawyer in the world now has 2 million bucks."

The engineer was non-committal and then said, "I always wished I could donate a kidney!"
