Klein Bottle Woolen Hats

What better to keep a mathematician's head warm this winter than a Klein Bottle inspired knit hat? You can get one for yourself (or your favorite mathematician) from Acme Klein Bottle.

Geek Cakes!

While I've been posting the occasional geeky cake here, I should have realized that there would be an entire blog devoted to the subject. Super geek cake categories:

• maths
• chemistry (check out the pictured cake!)
• physics
• gaming

Such yummy-looking geekiness!

Geeky Timepieces: Radian Wall Clock

This math-nerd clock tells time in both degrees and radians. You can get yourself one at CafePress.

Acme Klein Bottle

A Klein Bottle is a geometrical wonder. It's beautifully shaped, but has no distinct "inside" or "outside".  It would be the perfect gift for anyone with a love of geometry - or pretty glassware. the primary purveyor of such objects is Acme Klein Bottle, owned and operated by  Clifford Stoll. As he describes it: 

At last, Acme has conquered topological and engineering frontiers to manufacture genuine glass Klein Bottles. These are the finest closed, non-orientable, boundary-free manifolds sold anywhere in our three spatial dimensions.

These elegant bottles make splendid gifts, outstanding classroom displays, and inferior mouse-traps. With its circle of singularities, an Acme Klein Bottle can be said to exist inside of itself -- especially handy during time-reversals.

I think they would make the perfect geeky wedding or housewarming gift.

Mathematical Needlework

 Mathematicians Sarah-Marie Belcastro and Carolyn Yackel collaborated on the perfect book for knitters who love mathematics and mathematicians who love knitting: Making Mathematics with Needlework: Ten Papers and Ten Projects. From the description: 

Every chapter (except for the introduction) has four sections. First, there's an overview intended for both crafters and mathematicians, so it should be understandable to mathematicians who don't know anything about crafting and also for crafters who don't know anything about mathematics. Then, there's a section of detailed mathematics which is intended for mathematicians. All of the authors have made an effort to include basic information so that mathematical enthusiasts who are not professional mathematicians can follow the bulk of the material. The third section of each chapter contains teaching ideas, and these range from elementary-school level to graduate level. Finally, every chapter has a project, with instructions written for and tested by crafters.

For more on mathematical knitting - and a few patterns - check out sarah-marie's mathematical knitting pages.

qtπ tee

If you are the kind of girl geek who likes to proclaim her cuteness, Geek Bouteek's qtπ t-shirt might be just for you (left).

Prime Number Posters

If you love numbers Perfectly Scientific's Prime Number Posters are perfect decoration for your office, lab or bedroom wall. 

For years Perfectly Scientific Inc. has been producing high quality posters of the largest currently known explicit prime number. Each poster is printed on thick glossy paper and measures 29 inches by 40 inches **. Framed and unframed posters dating back to June of 1999 are available for purchase.

The current largest prime is 2^32582657-1 and looks, from a distance, like grey scale noise. It's not till you get up close (or use a magnifier) that you can actually see all the digits.

Get Ready for Fall: Pi Scarf

The greatest thing about this crocheted pi scarf created by Craftster mellifluousfondue is that you can make it as long as you like and the digits never run out!

Math Whiz Clock

OK, so its official name is the "Pop Quiz Clock", but that makes it sound like it's a chore. You don't even really need to be an arithmetic whiz to use it, assuming you are familiar with the layout of non-digital clocks. I like it for it's "I love math" sensibility. Unfortunately, there's no price or purchase information on the web site, so I don't know how you would actually acquire one for yourself.

And, yes, I know that the equation for "9" actually comes out to 9.005 (when rounding off, anyway). I figure it's within the margin of error for the second hand, so close enough.


(Via Nerd Approved, who for some reason appears to think the clock involves calculus)

Pocket Enigma Machine

The Enigma machine was the cipher machine used to encrypt and decrypt secret messages by the Nazi Germany during WWII. Allied cryptologists working in Bletchley Park in the UK were eventually able to break the cipher, which provided significant information and may have hastened the end of the war by at least two years.  While newer encryption technology is now used, you can own a little bit of history with the Pocket Enigma machine: 

Designed exclusively for and only available through Bletchley Park, Pocket Enigma is a little cipher machine with a single wheel that rotates on the CD mount in a compact disk case. It works on exactly the same principles as the real Enigma machine used by the German armed forces during WW II.

If you get two, you and your girl geek could exchange secret messages that almost no one would be able to decipher.
