It's another Monday, which means once again, it's time to highlight some of the recent community submissions posted to the Math Craft corkboard. Additionally, I thought we'd take a look at the Mobius Strip.
It's another Monday, which means it's once again time to highlight some of the recent community submissions posted to the Math Craft corkboard. Additionally, I thought we'd take a look at the process of stellation and make some stellated polyhedra out of paper.Rachel Mansur of Giveaway Tuesdays posted a video from animator Cyriak Harris, which zooms into fractal hands, where each fingertip also has a hand and fingers. A few more details can be found here, as well as some other really cool pic...

Natural processes often create objects that have a fractal quality. Fractal branching patterns occur in plants, blood vessel networks, rivers, fault lines, and in several electrical phenomena. Many of these processes take lifetimes, or even occur on geological timescales. But this is not the case for electrical phenomena. They often occur near instantaneously. One example would be the branching patterns that sometimes occur in lightning.
By "God," I mean Morley Davidson, John Dethridge, Herbert Kociemba, Tomas Rokicki and about 35 CPU-years.
Think credit card numbers are just a meaningless jumble of digits? A sort of number soup? Think again! Your credit card number isn't even number at all but rather a composite of four separate numbers, each of which plays an important, fixed role.
Use motion math and layers in Adobe After Effects to establish a moving relationship between two objects. Control layers in After Effects using motion math.
It's Monday, which means once again, it's time to highlight some of the recent community submissions posted to the Math Craft corkboard. In this post, we'll also make a flexagon, which is a type of transformable object.
It's Monday, which means once again, it's time to highlight some of the recent community submissions posted to the Math Craft corkboard. I also thought that we'd try and create something known as an "Orderly Tangle" or "Polylink".

WonderHowTo is made up niche communities called Worlds, so if you've yet to join one, get a taste of what's been happening this week in the highlighted Worlds below...
In this math made simple series of tutorials the author shows how to find a percent of a number. He shows that to compute x percentage of something we need to movie decimal point in the percentage number two places to the left. There fore to compute the percentage of a number we multiply it with the modified percentage number which has its decimal moved two places to the left. He goes and demonstrates this method by solving many sample problems. If you are looking to find out the percentage o...
Another week has passed on the online battlefield as the CISPA legislation continues to grind away at our freedom. Here at Null Byte, we try to keep our community informed and knowledgeable at the same time—and that means creating content for them to learn from.
Following the first part in this series on advanced cracking techniques, we are going to go over how we can intelligently crack passwords using the old-fashioned bruteforce method. These unique cracking techniques aren't widely used, because most crackers are Script Kiddies who have no idea what the concepts are behind cracking passwords, thus, word won't get around too quickly.
How did it happen? How did your ultra-secure WPA password on your wireless network get broken into? Well, you might have just found yourself at the mercy of a cracker.
Here's a Math Craft project that takes less than 20 minutes, has an attractive, practical result, and is at least a little mind-blowing due to folding along curves.
It's Monday, and once again it's time to highlight some of the community submissions posted to the Math Craft corkboard. In addition, I thought we'd take a look at having fun with the geometrical properties of polygons and circles by using one of the best circles I know, the penny.
The noble board game has stalwartly staved off elimination in the face of more technologically advanced video games for four decades. Try as they might, video games just can't seem to surpass them as an easy-to-use diversion for large groups of seated indoor people.
With over 60 commercials, chances are you've seen one of the Get a Mac spots run by Apple, which brands Mac as intuitive and hip, compared to their boring and clunky PC counterpart. You also probably saw Microsoft's response in their I'm a PC campaign. But who are Mac and PC users really? Do jeans and hoodie-wearing yuppies really use Macs? Are the suit-and-tie types strictly operating PCs?
Need to know how to use your Texas Instruments graphing calculator for your college math or statistics class? You're in luck... watch this video tutorial to see how to test a population mean with a TI-83 graphic calculator.
Need some help with the mean for your math class? The mean is otherwise known as the "average" of a group of numbers. This video tutorial will show you how to find the average "mean" of a group of numbers.
In this math lesson, you will learn how to find the square root of a number without using a calculator. You can even find the square roots of large numbers by following this simple algorithm. The above video demonstrates how to find the square root by hand.
Besides Wikipedia and teachers (in that order), textbooks are the go-to source of information during our school years. Today, we take a look at what happens when the people writing these voluminous tomes get attacked by a sudden bout of ennui.
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 ...
If you haven't participated in this week's Math Craft project on the platonic solids, maybe this will inspire you to do so.
Giveaway Tuesdays has officially ended! But don't sweat it, WonderHowTo has another World that's taken its place. Every Tuesday, Phone Snap! invites you to show off your cell phone photography skills.
Google's hard at work beefing up their new Google+ social network, and while they continue to improve new features like Circles and Hangouts, they haven't lost track of their other online features already widely in use. If you're already a part of the Google+ project (currently closed to invites right now), you've probably noticed the changes in Picasa Web, but Gmail has been getting some great updates as well—and you don't have to be in the Google+ network to use them.
Developers have created many tools for testing the strength of passwords (1, 2); there are also plenty of tips for coming up with a strong password in the first place. But why do the grunt work when an app could generate a perfectly secure one for you?
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.
Food is the meeting place of left and right brainers: Culinary arts call for creativity, but is also deeply rooted in the What, Why and How of basic science—baking powder vs. baking soda, the rising of dough, the falling of a cake, etc. Below, two plays on left brain principles—the Möbius strip and the law of gravity—both executed with right brain flair.
If you're a believer in the power of logic, may as well skip the game tomorrow. Two math professors at the University of London have supposedly determined who will win the World Cup, and have displayed their findings as a sophisticated infographic:
Oh Alice Waters and her magical Edible Schoolyard! Back in 1994, Alice Waters and King Middle School principal Neil Smith, worked with the community to refurbish their 1930's cafeteria kitchen into a wonderland of food education. The kitchen along with a one acre garden was the begining of what turned into the Edible Schoolyard project.
Pie and pi lovers rejoice: whether you like eating pies or calculating their area, 3/14 is your day. March 14 is a holiday for both bakers and math nerds: Pi Day, where the day and month correspond to the first three digits of the most famous mathematical constant.

It's once again Monday, which means it's time to highlight some of the most recent community submissions posted to the Math Craft corkboard. I also thought we'd take a look at building a model that has appeared in numerous posts. It's the simplest of the intersecting plane modular origami sculptures: The WXYZ Intersecting Planes model.
It's Monday, time to highlight some of the community submissions posted to the Math Craft corkboard. One of these posts inspired me so much, I think it merits a closer look. Today, I present a "simple" method for making a golden spiral using just a straight edge, a compass, and a template, inspired by RJ Ellicock's golden ratio post.
We've provided Google insiders, Google's community managers, authors, and celebrities for you to add to your circles. This week, we've discovered over 100 brilliant photographers for you to follow.
