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...
Here at WonderHowTo we're overflowing with top-notch origami tutorials. However, when it comes to the lesser known art of kirigami, we could always use a couple more enthusiasts. Kirigami is a form of origami that (unlike origami) involves making intricate cuts, and the results are often incredible.
The best way to lay out hand-cut dovetails is with a ruler and simple math. This approach works for any dovetail layout, no matter the width of the board or the number of pins and tails. Also, learn how Rogowski quickly sets the dovetail angle with a simple reference guide drawn on the back of his workbench bench hook. Make an easy dovetail layout.
Not all tapes are created equal, so here are a few tips for making accurate measurements. “Measure twice and cut once,” is the mantra of all carpenters, but it won't make a difference if the measurement is inaccurate or your math is wrong. Accurately use a tape measure.

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.
Eric Gjerde is a master of origami who devotes much of his energy on origami tessellations. Some of his pieces fold nearly flat, forming layers that add just a hint of depth. These pieces look beautiful when lit from behind, due to the variations in brightness and color. Other pieces utilize three dimensions more fully, with repeated structures rising out of the flat page.

I wish there was more information about this impressively massive sonobe model, but all I can glean is that it appears to have been made by Imogen Warren, and was posted by Room 3. So awesome.
Just watched PBS origami doc Between the Folds last night. If you haven't seen it, I highly recommend it. It's a beautiful film, really inspiring. Lots of Math Craft-related subject matter. Available instant on Netflix, or for rent on iTunes.
The Museum of Mathematics, curated by George Hart, will be opening in 2012. Here are a few activities you can check out in the meantime.
This is just too cool. As soon as I saw this, I thought, "Math Craft!"
Back in August, Scientific American posted a slideshow fitting for Math Craft. Click through to check out a slideshow depicting beauty found in mathematical structures—including a beautiful knot theory chart befitting of this week's project.
A beautiful object by artist Torolf Sauermann; see more of his math art here.
I'll be putting up a real welcome post along with a quick project idea in a couple of hours, but if you managed to navigate to here before that time, I just want to say thanks for coming and wish that you return in a few hours.
Best snow art I've ever seen. And Wonderment has seen some good stuff: penis, AT-AT, more penis. (Ok, we like the little boy stuff.) But we also like math, and this snowdecahedron is one stylish geometric form plopped right in the middle of the sidewalk in Porter Square, Cambridge, Mass. Nice work, sushiesque.
Flickr user fdecomite showcases his beautiful portfolio of geometry-inspired papercraft. His dedication to the craft is astounding. Get ready to take a journey down the rabbit hole cuz this work gets trippy.

In 2008, Audiosurf came out on Steam, creating the psychedelic music game genre. If you haven't played it in the intervening three years, you're missing out on one of the coolest things in video games. The player selects any MP3 on their computer, then the game builds a unique level based on that song, which the player must then navigate whilst playing a block-matching, Tetris-like puzzle game. It's an incredibly compelling audiovisual experience, one with immense replay value and surprisingl...
When it comes to graphing and comparing functions, the TI-83 graphing calculator is the end-all device for math and science students. But one of the most entertaining aspects of Texas Instruments' powerful algebraic and trigonometric calculator is not the equations themselves, but rather the art that can be "equated" on them—just think of them as the mathematical equivalent of the Etch A Sketch.
If you take two flat mirrors and place them front to back and look at them, you can see an infinite number of reflections. While this is a self-replicating pattern and can be somewhat mesmerizing, it isn't anywhere as interesting as looking at the chaotic scattering of light that can occur between 3 or 4 spheres.
There are a couple of strategies for reducing fractions and each of them require a strong knowledge of multiplication tables. In this tutorial, learn how to cancel numbers when reducing fractions with help from a real math teacher.
