Discussion Overview

The discussion revolves around a humorous incident involving a fake exam created by students in a classical mechanics course, which included complex physics problems. Participants reflect on the nature of the problems presented and whether they could be classified as chaotic, coupled, and damped systems.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants find the prank amusing and clever, noting the laid-back reaction of the classmate who received the fake exam.
  • There is curiosity about the specific physics problems in the fake exam, particularly regarding their complexity and whether they could be considered nonlinear.
  • A participant questions the logistics of how the fake exam was presented without raising suspicion, suggesting that it was easier due to it being a take-home test.
  • Another participant raises the question of whether the problem can be classified as a chaotic, coupled, and damped system, inviting further exploration of these concepts.
  • A link to a related resource about bouncing balls is provided, potentially as a reference for understanding similar dynamics.

Areas of Agreement / Disagreement

Participants generally agree on the humor of the situation and the cleverness of the prank. However, there is no consensus on the classification of the physics problem as chaotic, coupled, and damped, as this remains an open question.

Contextual Notes

The discussion includes assumptions about the nature of the physics problems and the classification of systems, which are not fully resolved. The complexity of the problems and their specific characteristics are not detailed.

In university we had a take home exam for a fourth year classical mechanics course. Some classmates made a fake exam with problems involving a sphere suspended by springs in the center of another sphere bouncing down the stairs and some other such incredibly complex stuff not entirely outside of the realm of what we had studied and gave it to another classmate. I guess he tried his best for about an hour before he went to the prof with it.

Wow, that's so mean :frown: :smile:

and I think it can count as academic offense (if that were final exam).
 
Welcome to PF Underwaterbob :smile:

Ha ha, that is hilarious. Cruel, but hilarious.
 
Very clever! That is funny. How did he react when he realized it was a joke?

He was a very laid back guy, some said narcoleptic judging from his behavior in class. There was minimal outrage. :biggrin:

Interesting problem - definitely nonlinear. Please post it at PF.

He gave up after one (1) hour? That is a good joke.
 
How did they give it to him without arousing suspicion? Doesn't the teacher usually hand out the tests?
If I were the teacher I'd have forced the entire class the take the fake exam.

OP said it was a take home test. I am assuming that this would make it easier to do.

That does sound like an interesting problem. Was it held by 6 springs in an orthogonal configuration or was it more chaotic?

Does the problem describe a chaotic, coupled and damped system?
