| 14:52 | | * abudhabi__ has inherited a slide rule and learns to use it. |
| 14:53 | < abudhabi__> | This would have been fairly brilliant in school for tests banning calculators. So long as the teacher wasn't super old. |

| 15:07 | < Alek> | they're pretty awesome when you know how to use them. |
| 15:07 | < Alek> | slide rules and abaci can actually be faster for many calculations than using calculators. |

| 21:07 | <@macdjord> | Alek: I am dubious of such claims; I'm pretty sure that comparing an /average/ calculator-user to a lifetime expert slide-rule/abacus user. |
| 21:22 | < Kizor> | Isn't a calculator like a firearm in that you don't need to start your training from the user's grandfather in order to produce someone capable of using it? |
| 21:23 | <&McMartin> | Kiiinda |
| 21:23 | <&McMartin> | We here were all trained as algorists from the age of six, at the *latest* |
| 21:23 | <@celticminstrel> | I’m doubly dubious of such claims. How can a physical device be faster at computation than a computer? |
| 21:23 | | macdjord is now known as TorracTinsmith |
| 21:23 | <@celticminstrel> | Tho admittedly a slide rule works on a “lookup table” principal rather than doing the actual calculation… |
| 21:23 | <&McMartin> | Yeah, training in a slide rule takes One Session |
| 21:24 | <&McMartin> | The big issue with them is that there are dex checks~ |

| 21:25 | < abudhabi__> | celticminstrel: It's an analog computer. Highly specialized, as such things need to be due to their nature. There's nothing inherently stopping it from being similarly fast, as the major limiter is the user's manual dexterity in both cases. |
| 21:26 | <@celticminstrel> | Hmm… I suppose that’s true. You do have to press buttons to use a calculator. |

| 21:29 | < abudhabi__> | McMartin: One of my university teachers once told us a story about how, back in his day, he gave an answer to the tune of "63.875" on a test, due to using a slide rule to aid in operations. The actual answer was 64 because it was something stupid like 8x8. |
| 21:29 | < abudhabi__> | The examiner allowed it. 😛 |
| 21:31 | < abudhabi__> | To be clear, I'd still prefer to use a calculator, but the use case I presented prohibited calculators. Not sure how useful it would wind up being, because when using slide rules, you do have to have at least know the order of magnitude of the result. |
| 21:32 | < abudhabi__> | Which implies rather decent grasp of basic arithmetic, which is the thing being tested. |
| 21:33 | <&McMartin> | also for trained abacists: they can perform the operations at a much higher rate than an average calc user can punch in the numbers. Punching in numbers is actually quite slow |
| 21:36 | <@Torrac> | McMartin: That's my point. I've seen the speeds a professional data-entrist can get on a 10-key number pad. |
| 21:38 | <@Torrac> | The average calc-user is rather slow at entering the numbers because there are a *lot* of amateur calc-users. Whereas nobody uses an abacus unless its either their hobby or their profession, either case making them an expert. |

| 23:55 | < bluefoxx> | I just loaned one of my best friend's my slide rule because he seemed interested in learning to use one. It's a pretty clever device, but for my day-to-day an electronic calculator is more practical |
