NASA reports that the sun erupted late last night with a large solar flare—an M8.7 class flare. The classification is calculated according to the peak flux of 100 to 800 picometer x-rays near Earth measured from the GEOS weather satellite. There are 5 letter classifications for solar flares, each with a linear 1-9 number scale of severity. M is the fourth most powerful class, with X leading the way. But last night's earth-directed coronal mass ejection (CME), captured by the Solar Dynamics Ob...
This is probably the least "Mathy" thing I will ever post. In my opinion, it's impossible to have architecture that isn't mathematical in some sense, so I am posting it anyway. Two years ago, I made a papercraft version of a cathedral in Christchurch New Zealand (It was severely damaged in an earthquake earlier this year) and cut holes for all of the windows and lit it with LED lights. I gave it to my Mom as a Christmas gift. I thought it made for a pretty amazing "Christmas Village" piece.
In light of this week's Giveaway Tuesdays Photo Challenge, we've posted a thorough guide to experimenting with bokeh photography. Most of the resources require a DSLR camera, and an intermediate understanding of some of the more technical components of photography.
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.

There are a lot of fantastic video games out there. Indie Games Ichiban's bread and butter is making sure that you steer clear of the bad ones and embrace the good. But really, the biggest goal here is to help everyone have more fun. To that end, today a game is not recommended, but an event. If you like games—not just video games—but tabletop, board and even hopscotch, then PAX Prime is one of the best events you could possibly go to.
Meet DareDroid: sexy nurse, geek couture and mobile bartender, engineered into an all-in-one technologically advanced garment. Created by fashion designer Anouk Wipprecht, hacker Marius Kintel, and sculptor Jane Tingley, the team calls themselves the Modern Nomads (MoNo), and their series of garments fall into Wipprecht's invented family of "Pseudomorphs". Pseudomorphs are tech-couture pieces that transform into fluid displays—which is exactly what DareDroid does.
Finally, summer is just around the corner! And while there are delicious fruits and vegetables available nearly every season, summer yields some of the very best picks. Equip yourself with one or more of the tools below before your next trip to the farmers market.
Oat bran has the ability to lower cholesterol plus it contains fiber, iron, calcium, and trace minerals, vitamins A, E, & K and several of the B vitamins. Here's the nutritional lowdown. But really, how many bowls of oat bran can you eat every day? Luckily it can be added to lots of the foods you already eat without changing flavor or even texture. Here's how:
In the mid '90s, there was no such thing as a widely available indie video game. Brick-and-mortar stores were the only places for consumers to buy games, and magazines were the only outlets to hear about them. For video game creators, the need for a publisher to market and distribute was logistically essential to attract players.
Dactyloscopy isn’t going anywhere. Forensic science has much relied on fingerprinting as a means of identification, largely because of the massive amount of fingerprints stored in the FBI’s biometric database (IAFIS), which houses over 150,000 million prints. And thanks to the departure of messy ink-stained fingertips, biometric analysis isn’t just for solving crimes anymore.

How far would you go to be resourceful? Early Britons used each others' skulls as drinking cups and bowls. Recently, researcher Silvia Bello found human skulls with the top cut off laying in Gough's Cave, England. Skillful cut marks make it look like fellow humans scraped off the dead skin to clean the bone, and chips around the rim of the skull cup make it look like the edges were evened out for a better drinking experience. Researchers have found other skull cups in France and Germany, but ...
The costume I mentioned in my last post is taking longer than I thought it would be, but it's almost done! I'm hoping to finish it either this evening or tomorrow. All the little mods I've added have taken up more time than I thought... but isn't that always the way it goes? It seems like every time I plan out a project, it always takes me at least an hour or so more than I originally planned, usually more.
The New York Times reports on the perks of opting for digital TV antennas vs. paying for cable TV. With the exception of the occasional spotty signal, young viewers are finding antennas are the preferable choice, considering savings add up to half the usual cost for cable TV and internet access.
Johnny Knoxville and the Jackass boys have finally returned from their whirlwind world tour promoting Jackass 3D. Along with their return comes the long-awaited Honorable Mentions for the Jackass 3D Prank Contest. So, straight from the source, a note from Knoxville:

PopSci's Gray Matter explains how to "hack light", a simple project that calls for glow sticks, diagonal cutters and Drano. Here's the science behind it:
Ok, so these aren't exactly "donuts" in the traditional sense. They are beer-battered, deep-fried donut peaches. And my God, they look so insanely delicious! Get the story behind this genius idea at Lunch at Sixpoint. Recipe below.
China's latest futuristic project is a massive "3D Express Coach", a clever project proposed by Shenzhen Hashi Future Parking Equipment Co. as a solution to traffic in the extremely overpopulated country.
The Farmer's Market is finally here! I'm getting busy setting mine up and filling it with crops and I've seen some great pictures popping up on my feed of my neighbor's farmer's marketplaces.
Do Sale Signs Bother You? My main man ran over a large rock with our lawn mower taking a chunk out of the blade. I heard it hit and the mower stopped dead in its rotation. The mower now has this grinding sound and I don't know better... but I have a feeling that a few teeth out of the gears has been snapped off inside the engine.

This one smells like a fish story. It is not. Tuesday April 13, Dave and I got up to surf westward at 7 in the morning. First rate waves. Headache cold water....sun blocked by the cliffs. Fast, clean, beach break. 3-4 foot sets, mostly lefts. About 15 dolphins swam by. Blase blase. We always see dolphins. But then some bigass whale with barnacles breaches. We are speechless. It is about 20 feet from us. We follow it for about thirty seconds and pinch ourselves. Have-you-ever? No...
Architect Enrico Dini is an innovator in the world of 3D printing. Dini is racing to produce the first marketable printer that can print full scale structures on site. Development has been seven years in the making (which has left him nearly bankrupt, and cost him his marriage).
LEGO technic builder Sariel presents a mighty impressive weekend project: a motorized LEGO hand that emulates actual human movement. This feat of plastic engineering runs on a combination of electric motors and pneumatic valves.
The seated hammer curl using resistance bands is used to target primarily the biceps, however because the wrist remains perpendicular to the ground rather than parallel, the forearm also gets a workout.
External shoulder rotation exercises are done to work the rotator cuff. The rotator cuff consists of four muscles. They include the supraspinatus, infraspinatus, subscapularis, and teres minor. Each muscle works to rotate the arm externally (laterally) and internally (medially). The following are instructions for the cable external rotation shoulder exercise:
The largest muscle in the back is scientifically known as the latissimus dorsi. You might see it referred to as the "lats" or "wings." The lats are used any time you pull something. For example, when you open a fridge or a car door, you are primarily using your lat muscles. The lat pulldown is a great way to target the back muscles. The following are instructions for performing this exercise:
The superman exercise can be used to work the lower back (erector spinae muscle). This exercise also works the hamstrings, butt, and shoulders. Some experts maintain that the superman exercise overloads the spine in a potentially unsafe manner. Thus, contralateral supermans are usually preferred. The contralateral superman exercise involves raising only one arm and the opposing leg (e.g. left arm, right leg). With this technique, there is a reduced load on the lumbar spine. The following are ...

With this technique, there is a reduced load on the lumbar spine. The following are instructions for contralateral supermans:
The Smith machine shrug is a great way to target the trapezius muscle. Despite popular belief, the trapezius is not part of the shoulders. It is a back muscle that allows the shoulders to move in different directions (e.g. elevating and lowering the shoulders).
The double crunch exercise involves two movements: a traditional abdominal crunch and a reverse crunch or knee-in. The reverse crunch portion of this exercise is supposed to target the lower portion of the abdomen. However, it is important to note that whenever the knees move toward the chest from a supine position (on your back), the hip flexors are the prime movers.
The V-up is one of the more challenging ab exercises. While it may appear simple, there are several factors that make this exercise difficult to execute properly. Some of these factors include timing of the movement, counterbalancing, hip positioning, flexibility, and abdominal strength.
Flutter kicks are often used to work the lower abs. Generally, flutter kicks are performed at the end of an abdominal workout when the abs are fatigued. In reality, this exercise does very little for abdominal development. The main muscles worked are the hip flexors. So if you are trying to get the most out of your abs workout, there are better options.
The scissor kick is often used to target the lower abs. However, this exercise does a poor job of working the abs. The hip flexors do most of the work. This exercise can be used in a continuum of ab exercises, but it should not be used as a primary ab exercise.
This exercise is good for abdominal strength and endurance. It is safe and easy to do. The crunch is one of the most incorrectly performed exercises. This exercise works best when done slowly.
The supine abdominal bridge is a great core exercise. It is relatively easy to perform and requires no fancy equipment. While the abs are the primary focus, the supine abdominal bridge also works the thigh and hip muscles (e.g. gluteus, hamstrings, quadriceps). They each allow the "bridging" of the hips to take place. Here is how this exercise is done:
The prone (face down) bridge or plank is a great exercise if you are trying to develop the core. This exercise is unique in that it is done from a static position. There are no repetitive movements. The prone bridge strengthens the lower back, as well as several muscles in the upper body. If you are new to exercise, consider starting with a modified version of the prone bridge, then progress to a full bridge. A workout mat is recommended.
The modified prone (face down) bridge or "plank" is a great exercise if you are trying to develop the core muscles. This exercise is unique in that it is done from a static position. There are no repetitive movements. The modified prone bridge strengthens the lower back, as well as several muscles in the upper body. A workout mat is recommended.
