These coasters will match perfectly with your number lamp and your equation bookshelf, so long as all you care about is, uh, math.

The math coasters, which are available in a variety of classy colors (as pictured above), are sold in sets of five for $22. Numbers are, unfortunately, not included. It’s Etsy, though… if you search long enough, you’ll probably find something to complement your coaster set.

Perfectly at home at concerts, coffee chops, and the panels of hip webcomics–and crafter Casstasstrophie, who made these bags for a swap, happily shared the method to her math-loving madness. She made the emblem in Photoshop, which means anyone who can hack out a design can personalize to their heart’s content.

As a lit geek, I find this bag both adorable and terrifying, but Ernest Hemingway’s beard, for instance, would be completely acceptable for me. I have to check out this tutorial.

So geek is ThinkGeek’s thinking that they even have a recipe for Pi-tini:

The Pi Symbol Ice Tray sells for $9 USD. If you can shake anything 3.14 times, then I salute you. You are a true nerd. Plus you have ultra-accurate muscle control.

Just punch your date of birth into Bandai’s new Human Relations Calculator, press a button, and it’ll tell you your fortune. And if you add a couple of birthdays together, you can find out what sort of a relationship you have with the other subject of your math problems. Divide, and you’ll get fortunes for your neighbors and family; subtract the dates and you’ll find out how you jive with co-workers; add ‘em and learn about your friends; or multiply and learn about your love interests.

I guess the good news in all of this hocus-pocus is that the Human Relations Calculator only works in Japanese, so you don’t have to worry about what it says – unless, of course, you happen to speak the language. There are also a handful of mini-games in case you grow tired of the forune telling shenanigans. If you’ve just got to try one of these, they’re available from Amazon Japan for ¥2885 (appx. $30 USD). There’s also a simplified web version you can play with here. It all makes perfect sense now, right?

One of the rarest bits of gadget history you can find, this beautiful specimen of the highly collectible Hewlett-Packard HP01 LED calculator watch is available for auction over on eBay. There’s just over 2 hours left in the auction so if you want to get your geek on, you’d better get your bids in fast!

The Chemist shirt would have been much better if the ladies in it looked better.

Now there’s a sad geek shirt. You know what makes it worse? One Pluto year is equivalent to 248 Earth years, but Pluto was a planet for only 76 Earth years. What? You don’t think that’s sad? I don’t care.

Shirt with G.I. Joe-ish font ftw! I know the message has a kind of anti-geek twist, but it’s still awesome.

The Pi versus i shirt succeeds in making Math fun!

And I think the T-800 Bach shirt is a fitting way to end this post. I actually can’t decide if it’s funny or not because it’s such an old joke, but… Yeah it’s still funny.

Here’s the square root watch; I guess all that’s left to say is you can get this for $40 over at SkyMall. Also,what is 8:15 in square root time?

Now this, this would be the entrance exam at a Mensa Preschool. It’s made by Triple Nine Society, and while it’s a hell of a lot more difficult than the square root watch, it’s way cheaper at $12.60. It’ll be 9:27 by the time you figure out what 8:15 is with this one.

Of course these timepieces make for fun gifts, but they’re not really really smart or geeky because even if you put the equation for black holes in place of, say, 11, I’d still know it’s 11 because it’s on the upper right hand area of the clock. Upper left hand. Lower left? Can I phone a friend?

A real geek watch would ask you for the time. Solve that.

The Takumi CRASH Calculator apparently is designed to crash itself when it feels like it. Why, I don’t know.

Maybe the description from the product page will help shine some light on the manufacturer’s intentions:

Everybody has an impulse to CRASH! We seek for the excitement of crashing in this calculator. You will be driven to crashing with the unpredictable action it makes. Calculate to crash, get an answer to crash… Enjoy yourself by operating this uncontroll”

Now it all makes sense, doesn’t it? Idea Frames sells the CRASH Calculator in black, orange and light grey versions for the rather lofty price of $60 bucks a piece. And if you can believe it, they’re already so insanely popular that they’re currently sold out. I guess if you happen to have three Jacksons burning a hole in your pocket, you could buy one for the hell of it.

Just don’t try running the U.S. Treasury with one of these. I think that’s what Alan Greenspan did, and look where that got us.

The equation bookshelf comes from the imagination of estúdio breder. According to the designer, the incorporation of parentheses, square brackets and braces around your books and other tschotchkes isn’t just for show. It’s actually created to help you prioritize the sequence in which you plan on needing them. Put your most significant objects in the parentheses, then work your way out, just like you do when working a math problem.

At this point, it looks like the shelf is just a conceptual design, so we can only hope that the artist decides to produce these. If only I had one of these on my wall, so I could calculate the probability of that happening…

The clear, ice-like acrylic case inspired the name “Alaska” for this LCD calculator. While the pictures might make it look white, you can really see all the way through it, meaning that it transforms into whatever color lies beneath it.

When looking at the calculator from off-angle, the numbers virtually vanish beneath the tall cylindrical buttons. However, when looking head-on, the digits are completely visible. I also dig the cool dot-matrix LCD screen that’s got mod square pixels. The manufacturer, Area Plus, also makes a version with removable buttons “for fun & play game,” but I’m not sure why you’d want to do that.

The Alaska acrylic calculator can be found on Japanese online boutique Cataloger, and retails for ¥3675 (about $32 USD).

It’s got a full calculator with an LCD screen and the mouse even has a scroll wheel. Ergonomically, it definitely looks a bit sketchy. While I really like the idea of being able to do some quick math on the fly, I’m concerned that I might accidentally press some of the keys while “mousing.”

The mouse is compatible with Windows, Mac and Linux computers, and UK retailer Prezzybox offers ‘em for £14.95 each (appx. $30 USD.)

The Choc-U-Lator is cleverly packaged in a wrapper that would fool just about any chocoholic. While it’s not very fancy, and only does really basic math, it’s still a pretty fun little gift for the chocolate addict in your life. It’s available from my Japan’s Rakuten online mega mall for just ¥500 (about $4 USD plus overseas shipping.)
