How To: Make Yin-Yang Modular Polyhedra

Last Thursday's post demonstrated how to Make Yin-Yang Pillow boxes, which were based on equilateral triangles and squares. The units for making these boxes were created by Phillip Chapman-Bell, who runs an amazing origami blog and has a spectacular flickr photostream. Using these units, you can make also make 4 of the 5 platonic solids. I made an additional template based on the regular pentagon so that the dodecahedron can be built completing the set.

News: Math Craft Inspiration of the Week: The Curve-Crease Sculptures of Erik Demaine

Erik Demaine is a Professor of Electronic Engineering and Comp Sci at MI, but he is also an origami folder who has had work displayed at the Museum of Modern Art in NYC. He makes some beautiful models and intricate puzzles, but in my opinion the really inspirational work is the curved creased models. In Erik's own words describing the above models: "Each piece in this series connects together multiple circular pieces of paper (between two and three full circles) to make a large circular ramp ...

How To: Get the 'But How?' and 'Cheney?' Trophies in Payday: The Heist

The easiest way to get these two trophies in Payday: The Heist is to load up the map Slaughterhouse. Now, to get the 'But How?' trophy, you have to let the armored car fall into the building by itself. But how? Well, after the armored car gets knocked onto the roof the building, just let it sit there. Do not shoot the support cables. If you survive two waves of enemies coming in to get you, the car will fall by itself.

How To: Install Linux to a Thumb Drive

Let's face it, CDs and DVDs are a thing of the past. We no longer use them as a storage medium because they are slow, prone to failure in burning, and non-reusable. The future is flash memory. Flash memory is cheap, fast, and efficient. Eventually, flash drives might even replace discs as the preferred prerecorded selling format for movies.

Scrabble Bingo of the Day: TRAVOISE

Scrabble Bingo of the Day: TRAVOISE [n] Today's word is in honor of Joel Sherman, whose record-breaking game last weekend netted him seven bingo plays, one of which was TRAVOISE. A travoise is a type of sled, but no… it's not like a toboggan or snow sleigh. Though it can be, it's not used primarily on snow, but on any soft ground, like forest floors and gentle soils.

How To: Make a Mini Cannon From a Lighter

I love this project. It involves fire, projectiles, electricity, and is easy to put together from commonly available parts. This mini cannon fires airsoft pellets, is fueled by alcohol, and is made almost entirely from parts found in a standard BBQ lighter. The total cost is under $5. About half of the BBQ lighters out there have a divide in the gas reservoir which makes them not work for this project. In case you have trouble finding a suitable lighter, the exact one I use in this video is a...

How To: GPU Accelerate Cracking Passwords with Hashcat

How to Crack Passwords Faster by Putting Your GPU to Work with HashcatSecurity on the internet is always changing. Not too long ago, having a 10 character password meant that you were safe from all forms of hash cracking. Hash cracking is when you take a string of characters that have been passed through a cryptographic hash and try to reverse them. The normal processors that are housed inside of our computer cases are general purpose. The processors are not meant for handling complex math an...

How To: Fix a Bricked iPhone or iPod Touch After a Failed Jailbreak

I can't believe it, but I've actually read about dozens of people getting their iTouch, iPhone, or iPad stuck in a bricked recovery loop and then going out to buy a new one. This is overly unnecessary. When it gets stuck in the recovery loop, some people mistake themselves by thinking that it is impossible to get the device back into DFU (Device Firmware Upgrade) mode. Getting the device back into DFU mode would at least allow us to jailbreak the device, essentially bringing it back from its ...

How To: Make Icosahedral Planet Ornaments

In honor of the new Astronomy World, I thought we should look at a few planetary icosahedrons. The icosahedron is the most round of the Platonic solids with twenty faces, thus has the smallest dihedral angles. This allows it to unfold into a flat map with a reasonably acceptable amount of distortion. In fact, Buckminster Fuller tried to popularize the polyhedral globe/map concept with his Dymaxion Map.

SUBMIT: A Photo with a Nostalgic Theme by December 19th. WIN: JOYSTICK-IT Arcade Stick

It is always a bittersweet moment to find yourself looking back on the fond memories that seem to have taken place in the distant past. When your favorite song from 10 years ago comes onto the radio, or when a sudden scent reminds you of the summers you spent as a child—these types of moments tend to trigger the fondest of memories. For this week's challenge, we'd like to see a photo that captures a nostalgic feeling, whether it be your favorite childhood food, meaningful memorabilia you've s...

News: Mathematical Quilting

I got hooked on origami sometime after Math Craft admin Cory Poole posted instructions for creating modular origami, but I had to take a break to finish a quilt I've been working on for a while now. It's my first quilt, and very simple in its construction (straight up squares, that's about it), but it got me thinking about the simple geometry and how far you could take the design to reflect complex geometries. Below are a few cool examples I found online.

Scrabble Bingo of the Day: GRUYERE

Scrabble Bingo of the Day: GRUYERE [n] One of the most famous types of cheeses made in Switzerland, made from the milk of a cow. It's a hard yellow cheese named from its town of origin, Gruyère. The cheese can be spelled with or without the grave accent (`) on the è, though in the United States it's usually without.

How To: Find and Observe the Garradd Comet

If you haven't seen one, a comet is one of the most spectacular astronomical objects in the sky, partially because it is so close to Earth. At the closest, it is only 1.3 a.u. (194,477,400 kilometers) away from Earth. Comet C/2009 P1 Garradd was discovered by Gordon J. Garradd on August 13, 2009. It never comes closer to the sun than Mars's orbit. Usually, a comet moves fast, but it has stopped moving so fast recently, making it really easy to observe. It can be observed by a telescope or wit...

News: Exercise Makes Me Tired

I just got my first Christmas gift to myself today. I have to say I do often just get myself a few items. It's the only time of the year I buy anything. So to myself I gave a pilates dvd. I did it this morning and now feel like taking a nap.
