I did both I guess. And because I could not share it, teachers never bothered.

This gives me food for thought. I have young children, all under 10. The challenge is learning how to inspire them; you found a crutch that made learning less of a chore: converting the syllabus into chunks of code. I can already see that the my two eldest will both need very different answers, but if I can figure out what theirs is, I can hopefully help them focus where my childhood mind would wander during study se…

You sound like a good parent. For me finding these small ways to cope with the boring reality of schooling really made the difference

Last year I bought I used TI for my daughter who needed it for school. I got her the oldest version, the one which takes AAA batteries and communicates with the outside world through a serial link. A project like this brings to mind the possibility of stuffing a Raspberry Pi Zero in the battery compartment, hooking it up to the school WiFi, using a terminal app on the calculator to communicate with the Pi and in that…

One of my university teachers allowed us a double sided letter sized piece of paper during the exam and we could put whatever we felt like on it.

This was brilliant because 1. In real life, you don’t memorize random facts. That’s what reference books and the internet is for. 2. Making the cheat sheet actually forced us to understand the material so they we could sum it up and for it on the page. By the time we were done writing the sheet, we had memorized most of it anyway.

Yet another demonstration how school is completely out of touch with the jobs they’re claiming to be preparing you for.

Must be a market specific model, because that one shows up for me in the .com tld but not in the regional one :-( But from there I've started digging and they have so many different models with similar appearances... Anyone knows the difference between fx-82ES and fx-82SPXII?

FX-115ES Plus-2 is the model for the USA market. For other countries the same device (but in another color) goes by FX-991ES Plus-2. https://www.casio.com/sg/scientific-calculators/product.FX-9...

Thanks!! The naming is so confusing... How are we supposed to know that "115ES" and "991ES" are in fact the same thing?

I had an Econ teacher that did something similar but it was a note card. Thing was she reused the same bank of questions every semester and provided a study packet of sample questions that was a super set of the questions on the final. Some kids got wind of this and encoded the answers to the study packet on the index card. They were bizarrely accused of cheating.

It's because school is preparing students for life, where it would be outrageous to have written notes while presenting or speaking. What's next, someone else writing the words for you?

Whats next, paying someone in a poorer country to write your things for you while you 'work from home'

Yeeeah that's already being done for a a bunch of IT courses. Check out some of those "freelance work" sites, it's fairly obvious a bunch of those are someone's homework...

That’s interesting but I don’t understand how it’s at all similar.

With sufficient preparation I could pass any physics test without actually understanding physics. A Chinese room within the mind, if you prefer a philosophy reference. Thinking about it, I really should’ve gone with that analogy first — it keeps this in the category of languages.

I know you pulled it out of your ass, but your thought on the uncertainty principle and black holes is actually intriguing. A wave function that is fully localized in momentum space (as in has one definite momentum) has to be maximally spread in position space (as in its possible positions are diluted to the point of being everywhere so the odds of observing it anywhere are effectively zero).

IIRC some quantum properties like uncertainty have funny ways of being preserved in relativity. They pop out of the equations as unexpectedly nice coincidences, but they feel to good to be true. Like they clearly hint at some profound truth, but its on the tip of everyone's tongue yet no one can grab it.

I vaguely recall certain types of entanglement change in an interesting way under the Lorentz transform (don't hold me to that).

How is having the transcript of the presentation cheating and not just being prepared?

It's because school is preparing students for life, where it would be outrageous to have written notes while presenting or speaking. What's next, someone else writing the words for you?

It's because school is preparing students for life, where they would never have any chance to look anything up, and could thus only use their own memory.

And that "you won't always have a calculator with you" thing math teachers loved so much? Yeah that didn't age well.

Its a great mystery to me why American students have to buy expensive programmable calculators for course work. I vaguely remember reading that it is the result of lobbying by calculator manufacturers. In my country even undergraduate science/engineering students dont need a programmable calculator. Some undergraduate programs like CS don't need any type of calculator.

I got mine for 25 cents. They're fun.

A university teacher allowed us to use everything during the exam, including a laptop with an internet connection. The only rule was that you weren't allowed to use any communication with other people, like messaging someone or asking questions on forums. Needless to say, everyone passed that exam.

For myself, the most-hated part of every exam session was having to memorize everything. That's what made me fail every single exam I've ever failed. I just can't bring myself to stuff information into my head and then give it back later. It's not a storage device. Yet most other teachers insisted that I need to do everything from memory. 95% of my school and university "education" was to memorize something, then recite it, and then forget it forever.

This is not calculus specific, but how did you look up logarithms? With printed tables??

The same way as pi, e and other constants, log(17) is just that. I never had to convert them to some decimal approximation in calculus classes Edit: Ok, I remember now there was a statistics exam when we had something like Student's t-distribution tabulated on the exam sheet but I had to scrape my brain to find an example, it does happen though

> The only time I remember needing a calculator in my entire education

I’m not asking about calculus classes. You specifically said “my entire education”

So you never needed to convert log(17) to decimal in your entire education? Or you just converted it by hand like the Neanderthals did?
