So. I know this is a long shot, but I'm hoping I might be able to find someone in the #Ottawa Metro areas willing to part with one or both of these #calculators... Both of which have been discontinued by #HewlettPackard 🧮 🤓🥼
To my knowledge, this is the last mass produced RPN calculator - and it’s itself an homage , not without its problems. Still, a pleasure to use , and the lack of RPN calculators is something that saddens me. #calculator#calculators#hp#retro
I’ve had the Casio fx-CG500 for about a 18 months and it is one of my favorites. It is slower than the HP Prime and the TI-nspire CX II CAS, but still blows the TI-89 Titanium out of the water as far as speed goes. The huge touchscreen gives it a unique UI that is easier to navigate than the TIs. I’ve found that this is the best of my collection for linear algebra, and it is the easiest of my CAS calculators to use.
The fountain pen is a Hongdian 1851 Forest Rainbow <EF> inked with Diamine Emerald. I've been using it for about 3 weeks, and it is an absolute joy! It has quite a bit of heft but is perfectly balanced when posted, and the nib is smooth and consistent. The anodized aluminum is stunning in person!
Come and see the first pocket scientific calculator HP-35 🔢, aided in its development by Slovenian engineer France Rode, an excerpt from Prešeren's works on punched tape 📚, and a century-old IBM 010 card punch.
🧮🔢 In the museum, we also have a nice collection of calculating machines and calculators. Can you imagine having to carry around a Facit C1-13, weighing 6.75 kg, for simple mathematical calculations? 😃
A neat little thing you can do in most operating systems is to enter a mathematical equation in the system’s search field and get the result back.
This also works on GNOME Shell but if it’s not working for you, go to Settings → Search and make sure that the App Search toggle switch is on at the top and that the Calculator app’s toggle switch is on under Search Results.
(For some reason, the latter was off for me on Fedora Silverblue.)
school memory: calculator racing to 100 against a friend: enter "1 ++" then hit the = key really fast until the display showed 100. The Casio FX-82 was the fastest at this. Modern (algebraic) calculators can't do exactly this
💡🔢 A brand new addition is this Wang 700B programmable calculator from 1969 with an astonishing 32 Nixie tube displays 😍🤩. More details to come once we get to know it better.
mu42 is an emulator for the Pioneer series calculators HP10B, HP14B, HP17B, HP17BII, HP20S, HP21S, HP22S, HP27S, HP32S, HP32SII and HP42S and for the Clamshell series calculators HP19BII and HP28S. It base on the sources of the famous HP calculator emulator Emu48 and is published under the GPL. The emulator PC version is running...
"math isn't important anymore because of calculators"
(which I actually heard tonight from someone who should know better)
makes it clear that we, as a society, have really failed to empower people to understand what math actually is in the first place.
iPadOS 18 could ship with built-in Calculator app, after 14 Calculator-less years
Imagine making a sophisticated piece of hardware, and yet the news that keeps popping up is how that hardware is missing calculator functions. So much so, that when you do decide to finally make a calculator app for your hardware, it's apparently news.
Can't tell whether this is hilarious or depressing.
