How To: Make a Hyperbolic Paraboloid Using Skewers

In Monday's post, we created a sliceform model of a hyperbolic paraboloid. In today's post, we will create a similar model using skewers. The hyperbolic paraboloid is a ruled surface, which means that you can create it using only straight lines even though it is curved. In fact, the hyperbolic paraboloid is doubly ruled and is one of only three curved surfaces than can be created using two distinct lines passing through each point. The others are the hyperboloid and the flat plane.

How To: Make Sierpinski Carpet Cookies

Since it is now the holiday season, I thought we could spend this weekend making some baked goods that have mathematical patterns on them. In this post, we'll look at making cookies that have a fractal pattern based off of a modification of the pixel cookie technique.

Modular Origami: How to Make a Truncated Icosahedron, Pentakis Dodecahedron & More

Last post, the Sonobe unit was introduced as a way to use multiple copies of a simply folded piece of paper to make geometric objects. In this post, we are going to explore that concept further by making two more geometric models. The first is the truncated icosahedron, which is a common stitching pattern for a soccer ball. The second was supposed to be the pentakis dodecahedron, but through systematic errors last night, I actually built a different model based off of the rhombic triacontahed...

Modular Origami: How to Make a Cube, Octahedron & Icosahedron from Sonobe Units

Modular origami is a technique that can be used to build some pretty interesting and impressive models of mathematical objects. In modular origami, you combine multiple units folded from single pieces of paper into more complicated forms. The Sonobe unit is a simple example unit from modular origami that is both easy to fold and compatible for constructing a large variety of models. Below are a few models that are easy to make using this unit.

Math Craft Monday: Community Submissions (Plus Polyhedral Stellation)

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...

You Won't Believe They Roll: How to Build Half Circle and Elliptical Wobblers

If you thought the last post on Two Circle Wobblers was wild, then wait until you see what happens when you build wobblers out of two half circles or two ellipses. In both of these cases, the center of gravity still remains constant in the vertical direction, allowing them to roll down the slightest of inclines or even travel a significant distance on a level surface if given a push or even when blown on.

How To: Make a Two Circle Wobbler from CDs

One of my favorite simple projects is building two circle wobblers. I love how such a simple object amazes with its motion. The two circle wobbler is an object made out of two circles connected to each other in such a way that the center of mass of the object doesn't move up or down as it rolls. This means that it will roll very easily down a slight incline. It will also roll for a significant distance on a level surface if you start it by giving it a small push or even by blowing on it!

NORTHWAY Games: Cool Indies by a Restless Company on the Road

Game design is sedentary work. Generally its practitioners do their work with their butts planted securely in front of a computer in an office (be it home or away) as their muscles and verbal skills atrophy. Even game journalists are prone to this condition. Not so with Colin and Sarah Northway (pictured below), the husband and wife team behind NORTHWAY Games. Not only do they make really cool indie games, but they do it with just a laptop while traveling the world meeting indie developers of...

How To: Create a 365-Day Photo Diary on Your Smartphone

A diary or personal blog is a great way to recapture the days behind you, but to a photographer, the best way to remember the glory days is with a picture—one single photograph that best describes the day and your mood at the time. Do it everyday for a year and you'll have 365 pictures that will not only bring a smile to your face, but will help you understand what was important to you in life.

News: Hate Final Cut Pro X? Try Adobe Premiere Pro or Avid Media Composer

It's no secret. Professional video editors everywhere are irate at the newest edition to Apple's popular non-linear video editing software, Final Cut Pro X. As of right now, Final Cut Pro X has 503 five-star ratings in the Mac App Store. Not bad. But it also has 671 one-star ratings and 414 users who aren't sure what they think. It's such a bad update that it even earned itself a skit on Conan.

News: It's Not an Interview, It's a Sales Pitch

One of the common mistakes I see a lot of candidates make when they go to an interview is that they think it is a question and answer session. They approach the interview with a mindset that their role is to be prepared to answer a bevy of questions thrown at them. This puts you in a passive role, playing defense. A much more effective approach is to go into the interview with the mindset that you are a salesperson, and the product you are selling is you. You want to convince the employer tha...

The Brooklyn Grange: A Farm up on the Roof

Up On the Roof: Urban Rooftop Farming and The Brooklyn Grange So sometimes something inspires me so much that it makes me want to run to the rooftop of my eastside L.A. apartment and shout out at the top of my lungs "LOOK AT THIS, THIS IS AMAZING!". The Brooklyn Grange is one of those kinds of things.

News: Dead Body Cab

Ok this is what you would do: get a big black bag, one big enough to fit a body in, and fill it with rotting meat and fake blood. Hail a cab and bring the bag into the back of the cab with you, you of course would have blood on your clothes to make it look more realistic. Tell the cab driver to take you to like a lake or construction site and offer to pay him 500$ to do it. If they take you then get out and struggle to get the bag out of the cab and tell the driver to help you with get it out...

How To: Make Ninja Darts for the Lighter Mini Cannon

In my recent article, How to Make a Mini Cannon with a Lighter, I demonstrated how to make a powerful combustion cannon out of parts salvaged from a standard BBQ lighter. The mini cannon was originally made to fire airsoft pellets, but I felt it was time to revive the project with something new.

News: Gigantic Carpet of 750,000 Begonias (Assembled in Just 4 Hours!)

Every summer the city of Brussels assembles an enormous carpet of begonias, under the advisement of one hundred experienced gardeners. The project is planned far in advance, with illustrations and scale models based on a chosen theme (previously chosen have been the arms and shield of a town or commemoration of important events). This year's theme features Saint Michael striking down the dragon, the official protective image of the city, founded over 1,000 years ago.

Grow While You Go: The Bus-Top Gardens of New York City

If you were to look on the roof of your local city bus, what would you find? A little bit of dirt, most likely, and a whole lot of space. Precisely the stuff you'd find in an empty container garden! Enter NYU graduate student Marco Castro Cosio's Bus Roots, a project which, through installing gardens on the rooftops of New York City buses, seeks to "reclaim forgotten space, increase quality of life and grow the amount of green spaces in the city."

News: Handmade Living Paper Dolls

Inspired by Jules Verne sea demons, Bea Szenfeld's “Sur la Plage” collection includes 12 pieces handcrafted with cardboard. The idea of unconventional material constraints is a classic art school "test", as well as a typical (and somewhat tired) formula for competitive design reality shows. However, Szenfeld's garments do transcend the material and would surely win any Project Runway challenge.
