A Slinky makes a handy model of earthquake waves. See for yourself which waves may send you rocking and rolling, and which ones may bounce you out of your chair. Before this activity, you may want to read about waves in the earth. You can also see illustrations of the motion of P and S waves and the motion of Rayleigh and Love waves. What do I need? • A Slinky (two if you have them) • A partner Assembly Stretch the Slinky 6 feet (2 meters) or more between your partner and yourself. What do I do? The vibrating parts of the Slinky move back and forth in the same direction as the wave is traveling. 2. This time, sections of the Slinky move up and down, perpendicular to the direction in which the wave is traveling. You can also shake the Slinky from side to side. S waves and P waves are known as body waves. 3. This circular-motion wave models an earthquake wave called a Rayleigh wave. 4. What's going on? Surface waves are long, slow waves.

Rheingold, Howard; Weeks, Anthony (2012-02-24). A few months ago, my friend took her car to the dealership to get an oil change. My friend is a teacher and so she appreciated the free WiFi as she was able to work on grading her report cards as she waited on the oil change. The good folks who changed her oil, also took a look at her battery. "How much?" Answer: $249.99 --- including labor and disposal of the old one. She thought $249.99 sounded a bit high as she remembered her husband recently buying one for less than $100 and she knew how to install the battery herself. A few minutes later, the service man returned and said that he could give her the battery for $199 (install and disposal of old battery still included).

Coming soon to a 3D printer near you: human tissue and organs
While the media focus on the possibility of 3D printing assault rifles, something far more meaningful has been going on in a number of university and commercial labs across the US: research to print human tissue and organs. Though printing every other widget under the sun is happening by leaps and bounds, getting viable organ tissue is moving in baby steps. One week ago, San Diego-based Organovo announced a new milestone in this field, using 3D printing technology to assemble functioning sections of human liver tissue, which are viable for testing drugs, for example. In a presentation at the annual Experimental Biology conference of the American Society of Pharmacology and Experimental Therapeutics held in Boston, Organovo demonstrated its success at creating a three-dimensional structure, albeit thin, of actual liver cells.

Today, there’s a massive hole in the way we issue commands to our machines. While the traditional mouse and keyboard, and even newer technologies like voice recognition and multitouch screens, have served us quite well, these controls simply don’t map well to the potential of wearable computing. Imagine Oculus Rift controlled by a D-pad, or Google Glass driving us all to mutter to ourselves all day. There’s a need for a go-anywhere, 3-D interface that will be fulfilled by some technology, and Thalmic Labs hopes their Myo can be just that solution. The Myo is a band that you slide on your forearm, where it can read the muscle-based electrical impulses driving the fine motor controls of your hand. The best analogy might be a Kinect that works from within. “Hands are the ultimate tool for input,” explains Thalmic’s Stephen Lake. But for now, the Myo team is after redefining active inputs rather than interpreting passive activities. That sounds really tough, right? “Is it risky?

Emprendedores de base social en todo el mundo están demostrando con hechos que el discurso de la sostenibilidad no es una moda sino un compromiso real por transformar la realidad del mundo a partir de un modelo de negocio innovador. La Fundación Schwab para el Emprendimiento Social, con sede en Ginebra (Suiza), explica que este movimiento de empresarios jóvenes es una “tendencia global creciente” que promete cambiar el mundo. De hecho, destaca que en la actualidad las universidades están dedicando cursos completos para fomentar este espíritu, mientras que las empresas y Gobiernos están impulsando este tipo de emprendimiento con la creación de fondos de inversión e incubadoras de negocios. La presidenta de la Fundación Schwab, Hilde Schwab, de hecho ha manifestado que el emprendimiento social ya es reconocido como un motor de cambio en la esfera económica global.

How to (Legally) Boost Your Music Library Without Spending a Dime
Free yes but I don't think that'd constitute legal compared to the methods in the article. There are (arguably) easier ways to go about doing this, and such action is quite dubious legally. I'm not preaching to you, just sayin... It's really no better than pirating music directly. I've told my dad and sister this and they're skeptical for whatever reason; it's just that this method doesn't seem like piracy since piracy is all done on torrents (people think). Years back I used to do this, but then I realized it was dumb - and not right. If you're gonna do it, just do yourself a favor and look to file-sharing sites first because if you're going to pirate music, you might as well get decent audio (Youtube is getting better with their video and audio upload quality, but when I did it, they didn't even have any resolution options, let alone HD ones, meaning the audio was poop). edit: I'll admit that creative copyright is something that's really hard to deal with.

How to Make Picture Frames from Reclaimed Materials | Designer Trapped
A big thank you to Dap for sponsoring this project. As always, all opinions are 100% my own based on my experience. Y’all, I could not possibly be more excited to show you how to make picture frames for maps today! GAH! I’m so in love with this project and it was so affordable because we used an old pallet to make them, which cost us NOTHING. Materials needed: An old pallet (or any other wood reclaimed wood you would like to use)Maps (I purchased all of my reproduction maps at this awesome Etsy store)DAP Rapid Fuse Wood AdhesiveClampsTable sawChop saw or hand sawDrill and drill driver Optional if you want to be able to change your maps and suspend from pipe: *NOTE: Your pipe fittings must match the diameter of your pipe. How to Make Picture Frames (the SUPER easy method): 1) You will need 4 lengths of wood for each print. 2) Grab your Rapid Fuse and some clamps. 3) Squeeze on a small amount of Rapid Fuse over both pieces of wood. Don’t believe it’s that easy. That’s it! SQUEAL!!!!
Today I’m going to show you how to build a DIY Downdraft Sanding Table to help eliminate dust in your shop! This is actually and update to an earlier downdraft table and sanding box I made last year. I wanted this one to be a little bigger and I refined the design a little too. Now I know you love sanding your woodworking projects, right??? You strap on the respirator, grab your sander, your preferred sanding grits (80, 150, 220 for me), now stand there for an hour or more working through your grits while your hand goes numb and you look like Indiana Jones coming out of the sand storm. Okay, so we all (at least the sane ones) hate sanding. Before we get started, make sure to follow me on Instagram, Facebook, YouTube and Pinterest to keep up with all my latest builds and free projects! Here is what you’ll need for the project: Affiliate links are provided in this post for your convenience. Building the Downdraft Sanding Table 1. Begin by cutting the pegboard to size. 2. 3. 4.
