Not studying or doing coursework worked for me right up until Calculus. Then I barely passed. It made me sad.

I don't know if I already put this here, but when I don't know the answer I declare the variable X to be equal to the correct answer, then answer X.

I like how on page 3 the teacher writes, "Page is to big" instead of "Page is too big". Perhaps this abortion of an essay (which I doubt is real) is the result of being taught by someone who is so dumb, s/he doesn't understand the difference between to, too and two.

If it is real, I'm surprised the teacher continued grading after the first page.
However, if you take out all the BS, he's at least got the story right.

On a similar note, someone in our class asked another person to spell "AC/DC", the joke being to tell them they got it wrong if they forgot the lightning bolt. However, they answered "AC-CD"

Here's a question(rather than an answer) on my final from last spring- I think that out of some 250 students only one appreciated it and came up with a nice answer for (c).

6. (10 pts) The Optimus function measures velocity of a semi-truck with
respect to time t. Optimus(t) = 14t + 10, in miles per hour.
(a) (3 points) Peter Cullen drives the semi for 3 hours, starting at
t = 0. How far did Peter drive?
(b) (3 points) What was the acceleration of the semi at time 2?
(c) (1 point) Interpret Optimus'(t) in words:

I don't get it.... but I'm guessing the answer was prime? I just get 14. Unless I've forgotten all my High school maths.

I wrote and gave the test. (thanks!) Another test I gave, but that I didn't write, had a question submitted by a grad student that involved the airspeed of an African Swallow. The Coordinator for the class changed the problem a bit: but she removed "African" and put "barn" instead. Sad day.

"But, Sir, if you wanted to be highly scientific about it, you could tie a short piece of string to the barometer and swing it like a pendulum, first at ground level and then on the roof of the skyscraper. The height is worked out by the difference in a gravitational formula, which I have determined here this time on a long sheet of paper with a very long and complicated calculation."


Someone else wrote:
Gravitational? I don't see how that works. On the other hand, the obvious thing here is that the ideal pendulum's period scales linearly with its length (and EDIT not much else)... Bohr would have got that right.
I heard the same story told by a phys prof, but not attributed to any existing person (it also doesn't get funnier by having happened or not).


The force of gravity varies slightly depending on far you are away from the center of the earth. When calculating the period of a pendulum, the force of gravity, g, is given by F = G \frac{m_1 m_2}{r^2}, Where m_1 and m_2 would be the mass of the barometer and earth, and r would be the distance away from the center of the earth. It's a very annoying way to arrive at a solution.

Whenever I remember I enjoy going back over my answers and adding operations that don't change the answer.
Like:
    Multiplying everything by cos(314159265*pi)
    Adding very complicated expressions including hyperbolic trig functions logarithms of many bases just making sure to raise to the power of zero
    Division by |epi*i|
    and whatever other fun stuff that does not change the answer

Back in high school I was taking a concurrent intro to Astronomy class. One of the tests had the question "Name the four fundamental forces." I totally spaced and wrote:
Gravitation
Strong Nuclear
Weak Nuclear
and... uh... your infinite mercy?

It only garnered a "wow that's sad" from the prof...

I think the student noticed that (x+1)3 could be expanded to x3+3x2+3x+1 - that's what the stuff on the right side was. Thus the "Very funny skeptical scientist". At least, that's what I'm guessing.

I'm thinking the student noticed that the answers were the same, and then realised afterward that the questions were the same (hence the answers being circled, and the expansion being a side-note).

P.S. If you're wondering why I put the same question twice, you should see how many people got the first one right but the second one wrong.

not math, but true story:

My dad was in high school bio, taking a test where there were several microscopes or other exhibits stationed around the room. Each student would move to a station, observe the exhibit, answer a question about it, and then move to the next station.

The ground rules for this type of exam were simply "DON'T TOUCH THE MICROSCOPES", but of course some jerk would always ignore that and try to improve/adjust the focus.

So my dad gets to one of the microscopes near the end of the test, looks into it, and can't see anything at all, except that whatever he is looking at is green. Someone had apparently "adjusted" the focus so much that he actually squished the lens into the slide. And the associated question is: "How does this organism reproduce?"

Having no idea what he's looking at, Dad writes:

"uh... the missionary position?"

The next day in class, the silence of students taking another pop quiz was shattered by the uncontrollable laughter of the young female teacher grading the exams.

I could see how. If someone uses substitution and they don't change the limits of integration, you'd get the wrong answer. I'm guessing that's what most people ended up doing.

I was once asked the standard-issue physics question about estimating the height of a building using a barometer. Except this particular test asked for all the possible ways we could think of, with no penalty for incorrect answers. I can't remember all of the methods I put, but amongst my answers:

1. Measure the barometric pressure at the top and bottom of the building and calculate the difference in altitude.
2. Drop the barometer from the roof of the building, and measure how long it takes to hit the ground. Calculate the distance the barometer fell based on that measurement (d=(1/2)*a*t2+v0*t, a=9.8m/s2 v0=0)
3. Drop the barometer from the roof of the building, and measure the difference in time between when you see the barometer hit the ground and when you hear the resulting thud. Use this to calculate the distance the sound traveled.
4. Drop the barometer from the roof of the building. Repeat until it hits a random passerby on the ground. Look in the news for a story that says "a man was badly injured today after being hit in the head by a barometer thrown off the roof of a X-foot-tall building." X will be the height.
5. Wait for a natural disaster to wreck the building. Take the barometer and smash the rubble until there are no large pieces left. The height of the building is approximately 0.
