Must be future engineers...
 

While visiting Annapolis, a lady tourist noticed several students on their hands and knees assessing the courtyard with pencils and clipboards in hand.

"What are they doing?" she asked the tour guide.

"Each year," he replied with a grin, "the upperclassmen ask the freshmen how many bricks it took to finish paving this courtyard."

When they were out of earshot of the freshmen, the curious lady asked the guide: "So, what's the answer?"

The guide replied: "One."

I'll have to run that one by my kids tonight.

I use that one as extra credit on tests each semester.

I like the obvious ones that are always overthought! Well done.

I like to ask grad students this question:

What is the shortest distance between two points?






You see, the average student immediately goes back to some half remembered statement from a 7th grade teacher but the question that they answer is "What is the shortest distance between any two points?" rather than the one I asked. The answer to the question I asked? Zero.

It is as important to understand the question as it is to know the answer.

I'll have to remember that one for this semester.:tu

Re: Must be future engineers...
 

I must not understand this question then. If the answer is zero then they are the same point, making it one point. I would argue the answer, a straight line, is correct to the question you posed, otherwise there are not two points. (I am an electrical engineer, just out of school, but I got the degree lol.)

Am I wrong?

Re: Must be future engineers...
 

The question is "between two points" which means that you get to pick them. In this case, you pick them to be coincident since that would be the shortest distance (you can also place them infinitely close such that the distance approaches zero).

For "any two points" you do not get to pick the points, merely state that the distance (in 2 and 3 dimensional space but not in higher spaces) is represented by the straight line path between the two points.

The word "any" makes them completely different questions.

Re: Must be future engineers...
 

Agreed, but then couldn't your straight line be infinitesimally small? This way the length of said line approches zero... Correct?

Re: Must be future engineers...
 

a point is not a line. basic geometry.

The whole point is to pick on the lack of accuracy in the English language.

Re: Must be future engineers...
 

I understand that.. My point is that if you can place two points infinitesmally close together, you can draw and infinitesmally small line between them... thus making that answer still true. However, if the points are coincident (sharing the same space) then the answer is zero and not a line because the line wouldn't be between them.

No where did I say a line was a point, even though, technically you could argue an infinitesmally small line is a point because a point has no length or diameter, or width or anything.

I completely derailed this thread, sorry.:bh
