I would allow it, it's brilliant. The main learning benefit of cheat sheets comes from writing them, not from using them.

[-] [email protected] 94 points 3 weeks ago

This. Most classes in uni allowed us to have a limited number of cheat sheets and after writing them I rarely used them. Open book exams are a different beast though.

[-] [email protected] 58 points 3 weeks ago

One of my math professors would always ask if people wanted an open book take home exam or an in person exam. Those who had taken his classes before knew to never vote for the take home open book, but were always outweighed by the new folks. Hardest exams I took in college by a large margin

[-] [email protected] 12 points 3 weeks ago

Sounds kinda adversarial from the teachers perspective.

[-] [email protected] 5 points 3 weeks ago

Ehh moreso that the expectations of the student with all possible resources available are much higher than an in person exam from rote. Some proofs on the in person exam would be trivial as they were similar to ones in the textbook. Take home proofs could go several pages and require you to extrapolate from what was learned so far.

I take certification exams that are open book. I still create an index aka cheat sheet because typing it out makes me internalize what I’m reading. It’s also easier to refer to an index of a couple of pages vs several books in a time-bound exam.

As someone who spent a few years teaching math, this would be a cause for celebration! I would have had a classroom pizza party the next day. This is creative usage of problem solving math that I could only dream about a classroom of students could come up with.

[-] [email protected] 17 points 3 weeks ago

A great teacher would surreptitiously plant the idea to do this.

[-] [email protected] 7 points 3 weeks ago* (last edited 3 weeks ago)

Depends on the class.

I had a statistics course that allowed us one single sided page, but as long as your printer could handle infinitely small print, she didn’t care if you had magnification. You could hypothetically have keychain bible print for your entire book as a cheat sheet, it just wouldn’t help you in the allotted time.

My cheat sheet for R was nothing but codes because I’m not a coder at all (R and basic Linux are my entire coding experience, and it was fucking miserable) and that helped if I remembered to label the fucking codes. And LOL nope.

But I cheated in other classes by doing such nonsense as writing vocab on my shoes… in college language courses, which I paid for myself.. so dumb and counter productive.

I was never smart enough to cheat in regular school.. I just brute forced the work.. ironyyyyyyyyy

First mistake was to not specify a sheet size

OK, based on the comments, it's AI.

This one isn't. A sheet of paper from mythbusters.

[-] [email protected] 54 points 3 weeks ago

it's AI

Looks a lot larger than A1 tbh

Telltales: floor too shiny, machines on the sides dont make sense, inconsistencies in piping in the ceiling, random floating bits on the top right, a few big shadows that dont match the windows instead of many smaller ones

This image… I don’t know if it is AI or it isn’t… but it certainly feels like AI…

[-] [email protected] 30 points 3 weeks ago* (last edited 3 weeks ago)

That's how they make paper and a lot of other flat goods like tape. The manufacturer makes these gigantic rolls then there's this entire industry called converting where a company, a converter, takes it and process it down into a finished product. They may add adhesives, lamination or printing to it during the process.

You can go to a store and buy 3M tape but 3M doesn't actually make it like that. They make a 12ft wide, 10,000 ft roll that someone buys and forklifts into a machine that cuts it into a bunch of smaller rolls that you can buy

[-] [email protected] 11 points 3 weeks ago

Those machines are referred to as slitters. I designed and built 2 for 3M Abrasive division back in the 1990's. Talk about a process that involves less than reliable hardware, (I never met an air bar or pneumatic web sensor I didn't hate), and enough wishful thinking to achieve the speeds 3M wanted them to run at that would make an Alchemist proud. I was constantly amazed that my designs even worked at all.

The Adobe stock photos link says its generated.

[-] [email protected] 4 points 3 weeks ago

Holy shit. Ok I'm gonna make an ai to feed generated prompts into a generative AI, let it run for a week and sell the mountain of slop as stock photos.

[2] is ai generated or so it says. [4] is real but not as big, and not quite a ton, it says '307kg'.

[-] [email protected] 4 points 3 weeks ago

Called a Tambur, usally between 15-25 tonns. Reason not bigger / heavier is that then it starts to damage "crushes" it self.

Heard of someone writing in multiple colours and using tinted transparent plastic sheets to read it.

[-] [email protected] 18 points 3 weeks ago
[-] [email protected] 55 points 3 weeks ago

Should have specified that the paper must also be orientable

[-] [email protected] 51 points 3 weeks ago

I think that might be racist.

[-] [email protected] 15 points 3 weeks ago

At the very least spaciesist.

[-] [email protected] 12 points 3 weeks ago

Definitively dimensionist.

[-] [email protected] 51 points 3 weeks ago

I mean, defining the cheat sheet limitation in such a way for Math students is really just asking for it ...

[-] [email protected] 18 points 3 weeks ago

If the parameter is that it’s 1 sided then you don’t need to be this creative, just have a longer sheet

[-] [email protected] 4 points 3 weeks ago

I think the joke here is the one sided part. Paper sheet has two sides.

The shape student is using is called möbious strip and its pretty famous mathematical object for being shape with only one plane. Another one is Klein bottle and im sure there are other ones too.

[-] [email protected] 3 points 3 weeks ago

Yeah, but that would make them have two sides, one (or both) with writing on it.

I wouldn't even be mad. As long as they could explain what a Mobius Strip is, they can use it.

[-] [email protected] 25 points 3 weeks ago

just points

[-] [email protected] 17 points 3 weeks ago

Something something sheets are planar, but then also allow it because it's great.

[-] [email protected] 7 points 3 weeks ago

I'm no math teacher but I'd call that worth extra credit!

[-] [email protected] 6 points 3 weeks ago

Should get bonus points.

[-] [email protected] 6 points 3 weeks ago
[-] [email protected] 6 points 3 weeks ago

How else are you going to have a 1-sided sheet?

Hmm. Would the surface of a sphere qualify as a sheet? But I feel that is cheating. The inside would count as another side if you could only get to it.

Id only allow it if it was a seamless piece of paper (not taped together) lol

[-] [email protected] 20 points 3 weeks ago

i don't think that's fair because such papers don't exist
