Gotta go. My ride is here.
Ready to tackle big math problems.
Big math in the train.
The big slide rule is now hanging in my office in case I need to solve any big math problems.

@th

*envy*

That's awesome!

@futurebird @th invented by big math to sell more i'll take three
@th when your log is really big
@th There was one of these hanging in my middle school computer lab when I was a kid! We learned Napier's Bones, abacus, and slide rule as an intro to our computer course
@th logarithms forever!
@th @bleeptrack Ha! We had one of those on the wall at school too. I even learnt how to use it at school. 😃
@th I don't know how or what it is used for but it looks nice.
@th Great memories! Every math class had one of these back in the 50s and 60s.
@th When I saw the thumbnail, I thought it was behind glass that you break in case of big math problem emergencies
@th Whoa! Can you estimate how precisely you can calculate with it? :)
@th that one is double sided I seem to remember. Got a smaller Multilog upstairs somewhere and always found the folding pi scale most useful. Now where do I put the decimal point?
@th
If you like slide rules, we have many at the Computer History Museum, in first section of the exhibition.
When I take groups around, younger folks look ar them in amazement. Older folks recall them fondly.

Calculators: Abacus

Abacus, 500 AD

@th if you store books on it, it'll become big numbers library.
@th That is beautiful! Where did you get that?

@th

I had to look up a couple of those scales.

@th I had a sudden image of an Apollo-13 era engineer needing to urgently solve a world-ending catastrophic math problem with your giant slide rule and wildly thrusting it into the hanging pictures, knocking them all down, with the camera lingering on the shattered picture frames as a schmaltzy accent on the human cost of massive progress
@th I'm jealous! I want one for my office too
@th This rules. Also slides, presumably.
@th you must get FOUR digits of accuracy with that!

@th Thought of this yesterday when somebody was showcasing a card game with reflection questions and one of them asked »was war Deine größte Lehre im vergangenen Jahr« (what was your biggest lesson learned in the past year), with the ambiguity that »Lehre« (lesson learned) is also the word used in »Schieblehre« (slide rule).

I guess for you the answer to that card would have been clear!

@th "you won't always have a calculator"
@xssfox @th a calculator in your pocket is a ridiculous concept, but if you have a large spare room you could build a small data center and use it to run an LLM that can multiply two 4-digit numbers with >90% accuracy

@th

I remember this kind of things (at that scale): They were used in school by the teachers to demonstrate how to use a *Rechenschieber* (this how it is called in German language).

@th The one I have is definitely a lot smaller.....

@th A sliderule that size is clearly used for

long division

@th nice & really big!!! These are from my collection... used to do calcs a lot back to high school😁😁👍👍
