Smart rings may seem like something from an impossible (or at least highly unlikely) vision of the future, but surprisingly enough, tech you can wrap around your little finger isn't anything new. Just take this itty-bitty abacus from the 17th century as proof.
Already on Android for the past few months, this conceptually simple calculator app is finally available to iOS users. What may seem basic in theory becomes extraordinary in MyScript's execution, leaving you with a buttonless calculator you'd never think to want but can't imagine living without.
If you're going to have a calculator watch, why trifle? Why bother with something that only performs basic arithmetic? You're trying to make a statement, right: that math is important to you. You should be able to do basic operations in your head. If you're going to wear a calculator on your arm, please wear a badass…
Google's search-based calculator is a bit of a God-send when it comes to impromptu math, but now the Big G has gone and extended its functionality by rolling out a full-on, 34-button scientific calculator.
The folks at Google are no strangers to science, science fiction, fantasy, or geek culture in general. Evidence of their fandom is plentiful, most commonly in the form of easter eggs and April Fools' jokes, for which the company is famous. But you do have to know where to look. Consider this your guide to the ten…
Long before anybody dreamed of a shiny iPad or glistening ultrabook, engineers and scientists used to get down to business with mechanical calculators to compute their solutions. While the concept of a mechanical calculator sounds ludicrously simple these days, a peek inside one reveals that they're anything but.
This 1942 ad for a comptometer is just perfect because first of all, I had no idea what a comptometer was (a mechanical calculator, basically) and second, the spec sheet is wonderful: no glare dials, elimination of non-essential zeroes, and a "Keystroke Censor."
Asteroids headed for Earth are scary. So get to know them a little! You can use the Impact: Earth! calculator to see what kind of damage an asteroid will cause. It's totally not as scary when you crunch the numbers.
If we were given Casio's Prizm calculators in math class, perhaps I wouldn't have failed so dismally. Or maybe I would've got even worse marks—spending the 60 minutes of every class searching for Solitaire and Minesweeper.
Who needs Texas Instruments? Not Matt Stack, creator of the Open SciCal. His homemade, 100% open source graphing calculator not only blows away the functionality of store-bought devices, but is the "ultimate status symbol among the nerdiest of the nerds."
In 1996, you could get a Palm Pilot 1000 with a 16MHz processor, 128KB storage, and a 100-name address book for $300. Times sure have changed! Like, what about a TI graphing calculator?
It's just a calculator. But a very nice one, designed by Canon's camera group, and it uses recycled PowerShot lenses for the glass elements. It's thirty dollars.
We're kicking off our series exploring memorable gadgets from memorable people with one of the most influential tech giants: Steve Wozniak, co-founder of Apple. – JC
Nerds of the world jump of happiness, for HP has brought the legendary HP 15C Scientific Calculator and the HP 12C Financial Calculator for the iPhone and iPod touch, complete with custom skins and programming.
From a fitness and educational standpoint, I understand the idea behind the Alpha Mat. It provides a plyometric type of workout while engaging the mind with numerical sequences—but it's missing a key ingredient.
It must be creative pipe week here at Gizmodo, because people keep sending in their awesome creations. And this might be the best one yet: a functioning TI-83 calculator with a pipe built into it.
