CASIO JAPAN DESIGN
Count on Casio calculators now and forever. For 60 years, Casio pocket calculators have been easy to read, easy to use and durable. Today, however, we are redesigning their core identity from scratch to create a new future for computing.

Wonderful stuff.

Not a Casio but...
I found and turned on my (50?) old Sharp Elsi Mate EL-331 solar calculator, it came to life straight away.

🎉 Wow, who knew the history of #microcomputers was just a parade of unpronounceable names and numbers? 😴 Let's not pretend anyone's life changed with a 20-pound "micro" computer, probably better at launching a spaceship than solving a math problem. 🚀 #Calculators everywhere are shaking in their pocket protectors. 📟

The first microcomputer: The transfluxor-powered Arma Micro Computer from 1962

What would you say is the first microcomputer? 1 The Apple I from 1976? The Altair 8800 from 1974? Perhaps the lesser-known Micral N (1973...

AI Today, Calculators Back in the Day

An article about the dangers of AI dependency reminded me of how I encouraged a middle schooler to do algebra by hand in my senior year of high school.

AI Today, Calculators Back in the Day

An article about AI dependency in 2026 reminded me of my advocacy for not relying too much on calculators back when I was in middle and high school in the 2000s.

https://arxiv.org/pdf/2603.21852 This is interesting! All functions on a scientific calculator can be reduced to just '1' and this dyadic function 'EML'. @NanoRaptor If you ever felt like creating an HP voyager calculator with a very limited number of buttons... I think we could get away with just '1' 'EML', roll down and x<>y. Maybe on. And the most important one '%'. :) #calculators #rpn

Quanta Magazine 🤓 wonders if digital proofs are the end of rigorous math as we know it. Maybe next week they'll tackle whether #calculators are ruining the joys of long division. 📉🔢

In Math, Rigor Is Vital. But Are Digitized Proofs Taking It Too Far? | Quanta Magazine

The quest to make mathematics rigorous has a long and spotty history — one mathematicians can learn from as they push to formalize everything in the computer program Lean.
