Sound installation by Alex Allmont uses old LEGO to create a machine to generate electronic music - video embedded below:
Play house is an automata that mechanically computes and performs hooky and hypnotic acid house. Like a generative musical loom, a single drive turns a sequence of LEGO gears, levers and latches that mutate riffs and rhythm patterns. These are played out on analogue drums and synthesisers from the halcyon days of 1980’s dance music while the machine gradually shifts the timbre and space of the sound. In the piece the process of creation is laid bare so one can indulge in picking apart the interactions driving the score, seeing sound as it changes in sculpture, exploring our expectations in music, or simply rocking out to some fruity acid.
If Earth’s water were drained into a single drop, it would measure about 950 miles in diameter. Roughly three percent is fresh water, and just one-third of that is easily accessible. Meeting the growing need for water is a critical challenge. Many countries rely on desalination to produce fresh water, but current techniques are typically energy-intensive, using enough energy globally to power nearly seven million homes. That’s why today GE is launching an open innovation challenge to improve the energy efficiency of water desalination. Find out more about the challenge here.

Everything you need to know about checking the four upcoming lunar eclipses here.
Just in case some of you guys were curious what the different types of Lunar eclipses were, here’s a neat little gif-tastic diagram of the three types. Also handy is a calendar for the next ones, although the majority of America won’t be able to see a full total eclipse again until 2017.
The first of four eclipses in a series, the Lunar Saros 122. A saros is a fancy way of determining patters in relation to time relating to Earth-Moon solar geometry, so I present to you a Wikipedia article on the topic. For this eclipse cycle, though, their are no intervening partial eclipses of the Moon.
This is beautiful and it’s amazing to me that it had such a positive outcome and not lifelong hateful grudges, which is probably what these attackers deserved.
This is perfect and beautiful and amazing
Yep, those are tears coming down. This is one of the most beautiful pieces I ever read.
Damn, the level of compassion, strength and understanding you’d need to have in order to do this..
2 magnets disk on a axle
4.5 Volts 2Amp
2 aluminum bands on plastic
The Laplace rail is a good demonstration of the ‘right hand curl rule’
Using a hand as a guide If we have a current moving in the direction of the thumb, the magnetic field will be oriented in the direction of the curled fingers
When the current is applied the only way for the circuit to be completed is through the axle. Given the red terminal is positive the current is moving from left to right through the axle generating a circular magnetic field that is oriented towards the viewer.
The magnets on each end of the axle are now repelled by the field generated by the current and force the axle to move. If you were to switch the terminals the axle would move towards the viewer - this is demonstrated in the later half of the video which can be found here.
Bear On Stairs
Stop-motion looping animation by DBLG uses 3D printing to create models for each frame of a bear climbing stairs - video embedded below:
DBLG’s in-house studio projects are a platform for us to experiment with creative ideas and above all have fun. For The Stairs Project we wanted to explore the use of stop frame animation with 3D printing.

You want to say Hi to the cute girl on the subway. How will she react? Fortunately, I can tell you with some certainty, because she’s already sending messages to you. Looking out the window, reading a book, working on a computer, arms folded across chest, body away from you = do not disturb. So, y’know, don’t disturb her. Really. Even to say that you like her hair, shoes, or book. A compliment is not always a reason for women to smile and say thank you. You are a threat, remember? You are Schrödinger’s Rapist. Don’t assume that whatever you have to say will win her over with charm or flattery. Believe what she’s signaling, and back off.
If you speak, and she responds in a monosyllabic way without looking at you, she’s saying, “I don’t want to be rude, but please leave me alone.” You don’t know why. It could be “Please leave me alone because I am trying to memorize Beowulf.” It could be “Please leave me alone because you are a scary, scary man with breath like a water buffalo.” It could be “Please leave me alone because I am planning my assassination of a major geopolitical figure and I will have to kill you if you are able to recognize me and blow my cover.”
On the other hand, if she is turned towards you, making eye contact, and she responds in a friendly and talkative manner when you speak to her, you are getting a green light. You can continue the conversation until you start getting signals to back off.
The fourth point: If you fail to respect what women say, you label yourself a problem.
There’s a man with whom I went out on a single date—afternoon coffee, for one hour by the clock—on July 25th. In the two days after the date, he sent me about fifteen e-mails, scolding me for non-responsiveness. I e-mailed him back, saying, “Look, this is a disproportionate response to a single date. You are making me uncomfortable. Do not contact me again.” It is now October 7th. Does he still e-mail?
Yeah. He does. About every two weeks.
This man scores higher on the threat level scale than Man with the Cockroach Tattoos. (Who, after all, is guilty of nothing more than terrifying bad taste.) You see, Mr. E-mail has made it clear that he ignores what I say when he wants something from me. Now, I don’t know if he is an actual rapist, and I sincerely hope he’s not. But he is certainly Schrödinger’s Rapist, and this particular Schrödinger’s Rapist has a probability ratio greater than one in sixty. Because a man who ignores a woman’s NO in a non-sexual setting is more likely to ignore NO in a sexual setting, as well.
So if you speak to a woman who is otherwise occupied, you’re sending a subtle message. It is that your desire to interact trumps her right to be left alone. If you pursue a conversation when she’s tried to cut it off, you send a message. It is that your desire to speak trumps her right to be left alone. And each of those messages indicates that you believe your desires are a legitimate reason to override her rights.
For women, who are watching you very closely to determine how much of a threat you are, this is an important piece of data."
an excerpt from Phaedra Starling’s “Schrödinger’s Rapist: or a guy’s guide to approaching strange women without being maced” (via lostgrrrls)
HOLY FUCK THE TRUTH.
Can every one of my male followers read this? And please, before you get defensive (“I would never rape anyone!”) keep in mind, women being afraid of Shrodinger’s Rapists (oh my god i still can’t get over the encompassing brilliance of this phrase) is a conditioned, learned response from being immersed in rape culture and the evolution of sexism and sexual violence in our society from the day we’re born. And unfortunately, it’s very difficult to unlearn without the efforts of all genders to dismantle it. Which is where you come in.
It’s also just rude and disrespectful to patently ignore what someone has told you regarding their personal space, body, and time. Get a clue.
I will always reblog this. Always.
JPL Engineer explains how they are testing the next generation of Mars parachutes in the video “LDSD: We Brake for Mars”
One of the answers to the topic: Visually stunning math concepts which are easy to explain at Mathematics Stack Exchange.
I think if you look at this animation and think about it long enough, you’ll understand:
- Why circles and right-angle triangles and angles are all related
- Why sine is opposite over hypotenuse and so on
- Why cosine is simply sine but offset by pi/2 radians
Each of these cotton pillows feature a vivid image of a galaxy. Measuring 12” x 16”, they make a perfect accent for any room, or a bit of added comfort to your bed. Sold on Etsy.

THIS IS IMPORTANT.
Just a fraction of the cool stuff I learned when researching women’s history.
On the eve of the Boston Marathon, we at Spartan Race, along with the country, pay tribute to all the victims and survivors of last year’s attack.
Pictured are athletes and citizens who lived through the events and won’t let tragedy grind them to a halt. This series shot by Robert X. Fogerty for Dear World captures the resilience of those affected that can’t be dampened. Please visit their site to learn more about these people’s stories and pay tribute.
Boston is as strong as community as the world has. We are proud to be part of it. On Marathon Monday, we will be there and along with the rest of the world, we will be watching a city recover as one.
Robotic recreation of the Kangaroo form put together by Festo to demonstrate energy-efficient movement (this was initially announced on April the 1st, but turns out to be real) - video embedded below:
With the BionicKangaroo, Festo has technologically reproduced the unique way a kangaroo moves. Like its natural model, it can recover the energy when jumping, store it and efficiently use it for the next jump.
On the artificial kangaroo, Festo intelligently combines pneumatic and electrical drive technology to produce a highly dynamic system. The stable jump kinematics plus the precise control technology ensure stability when jumping and landing. The consistent lightweight construction facilitates the unique jumping behaviour. The system is controlled by gestures.
Meet Claudia Mitchell, the first woman with a bionic arm.
In 2006 she was outfitted with the arm to replace the arm she lost in a motorcycle accident. Her prosthesis, a prototype developed by the Rehabilitation Institute of Chicago is one of the most advanced prosthetic arms developed to date.
Mitchell, who lives in Ellicott City, was the fourth person- and first woman- to receive a “bionic” arm, which allows her to control parts of the device by her thoughts alone. The device works by detecting the movements of a chest muscle that has been rewired to the stumps of nerves that once went to her now-missing limb.
She hopes to upgrade to a prosthesis, still under development, that will allow her also to “feel” with an artificial hand.
A while after the initial surgery, surgeons took the first step by rewiring the skin above her left breast so that when the area is stimulated by impulses from the bionic arm, the skin sends a message to the region of her brain that feels “hand.”
Future arms will be able to perform even more precise movements, but even the first-generation device “has changed my life dramatically,” she said. “I use it to help with cooking, for holding a laundry basket, for folding clothes — all kinds of daily tasks.”
Technology like this gives hope for the future because it is a great example how science can actually improve the quality of people’s life!
You can see a video of her using her bionic arm here:
