Of course, students two and three will be the best engineers. Student one will give you all the wrong answers that are in the texts, all the wrong answers when typos are made, etc. Student four will give you lots of wrong answers, on the advice of self-proclaimed experts. (after all, being somebody's "mum" doesn't make this woman any more likely to be able to cook a good steak.) Students two and three each will be valuable engineers, and are the sorts who are more likely to catch other people's mistakes, and verify that their own answers are consistent with nature.I tend to disagree. There are no good engineers in the bunch, but all of them have good qualities (er, behaviours | practices | habits..).
Tachyon said asked "Which student will make the best engineer?", and all but the last are equal. If he askeed his mum why, would be as equal as the rest.
You can't be a good engineer and stick only to one practice. You have to understand the theory, experiment with proper procedure to ensure you understand the theory, and that the theory is sound and applicable....
basically, your reasoning against one and four is wrong. Tyepos my pipmpersnickle. Who's to say "mum" has to be his mother (it's a codename for the best engineer on earth, a true expert).
What if four had a faulty thermometer, and three didn't know how to conduct the experiment properly (which by the way was faulty. It took him waaay too long to cut the meat and take the sample, that all his results are 10 degrees off, due to loss of heat whilst he cut).
Anyway, like I said, a good engineer will have all of the four qualities.
update: oh yeah, when you assume, you make an ass out of you and me, and mostly you, cause you're in charge of the project (and i'm the dumbass who hired you :D)
