As some of you Mad Science readers will remember, we recently covered the separation of water into hydrogen and oxygen using electrolysis. Passing a current through water can rend it apart, but we can also recombine that oxygen and hydrogen to make electricity! This is the principle behind those vehicles run by hydrogen fuel cell engines.
I write this post as an afterthought on the recent mass burnings of the Quran by U.S troops. Let me lay down the facts first to clear any misunderstandings:
It seems the Republicans aren't happy about Obama. But then again, they never will be. As the time for re-election draws near, the Republican Party is scrambling to chose their candidate who will beat Obama. So far, Mitt Romney (we'll discuss the candidates soon) has somewhat dominated the scene, with spurts of awesomeness from Rick Santorum and Newt Gingrich. Ron Paul stays steady, currently holding the second most number of delegates (yes, we'll go over terms also).
Let's face it, the world we live in is far from the fairy-tale land we want it to be, where violence doesn't exist and weapons are not needed. Our foremost goal in life out there in the scary world is simply to survive. And if we need a few tools to accomplish this, we should use them, right?
Here is our entry for the Greek building contest. It is a model of the theater at Epidaurus. Here are our favorite images and descriptions out of those we used to build it: 1 2 3 4
In this article, I'll show you how to make a simple touch-triggered switch. This is very useful for various electronic projects, from a simple bedside light to a flat panel touch keyboard. The circuit can vary in switching power depending on the transistors you use. For example, if you're looking into creating a 120V light that turns on when touched, you'd need two powerful transistors and an isolation relay. However, a simple flashlight that turns on when touched would only take a couple of ...
Sage Workshop: Intro to Poetry/ Autobiography Unit Essential Question: How can my five scenes are used in my writing?
There was a huge ban wave recently on Xbox Live. In the unfortunate event that you decided to do something against Microsoft policy, and have consequently gotten yourself banned from Xbox Live, you may have come to the realization that doing whatever got you banned from Xbox Live in the first place was not worth the risk.
Scrabble Bingo of the Day: CABRESTA [n/pl.] A cabresta (also cabestro or cabresto) is simply a lasso, a rope formed with a running noose that's used on ranches and Western plains for catching horse and cattle. Cabresta comes from the Spanish word halter, which refers to the headgear used for leading or tying up livestock and other animals. But halter also used to mean to hang someone by roped noose, which could be how it became popular as a term for a noosed lasso.
The already robust and ingenious Nmap tool has received a whole slew of new scanning scripts that can be used to do all sorts of naughty endeavors. Notably, the SQLi module, since it is a necessary evil that we must cover here at Null Byte. This major update is going to fuel today's lesson.
Null Byte is looking for forum moderators! Last Friday's mission was to accomplish solving HackThisSite, basic mission 9. This mission delves a little further into Unix commands and remote directory traversal (which is just a fancy term for going through folders blindly).
Scrabble Bingo of the Day: * FINNESKO [n/pl.] A finnesko is a boot made of tanned reindeer skin, with the reindeer's fur on the outside. It's an especially good, warm boot for subarctic regions. These boots originate from the Sami, indigenous people from the cultural region of Sápmi, located across four countries in the Arctic Circle; Norway, Sweden, Finland, and Russia. This area is also referred to as Fennoscandia.
Scrabble Bingo of the Day: * CAGANER [n] A caganer is a small figurine of a person defecating in place, pants humorously around the character's ankles. It's a traditional Christmas decoration in Catalonia, Spain and in neighboring areas, where it's placed within the nativity scene.
I've come across a few very stubborn Xbox consoles in my day. A previous Null Byte demonstrated how to fix the Xbox with just eight pennies and some electrical tape. But if you've got one of those hell-born boxes that just refuses to be fixed in any way, shape, or form, there is always one last ditch approach. I'm talking about the infamous "towel trick". It works over 90% of the time, from my personal experience. Though, please note: This is only a temporary fix.
MineCon 2011 (held at the Mandalay Bay in Vegas) was in a word, awesome. The crowd was overwhelmingly young, the vibe was fun and nerdy, and best of all, the costumes were inspired. Below are my favorites, which unfortunately aren't of the best quality (lighting was low and super yellow, which wasn't helped much by my standard point-and-shoot). If you happened to attend Minecon as well, post about your experience to the community corkboard... if you're pictured below, please comment!

Most kids who play video games will never become professional gamers. Those that do are part of a very select group— it's like being a professional actor or athlete. It's nice work if you can get it. For everyone else, the sad realization usually arrives sooner or later that time spent playing games might not have the practical rewards that homework or working hard at your job might deliver.

Video game controllers are our windows into the soul of the machine, our sole means of interacting with them. More often than not, consumers seem displeased by their controllers; it's comforting to blame sticky, poorly laid out buttons for messing up your game than your own lacking skills. The original "fatty" Xbox controller was so large it caused mass consternation and prompted Microsoft to replace it with a smaller version in a matter of months.
Electronic Arts is the biggest game publisher in the world, and have been for years. And yet, their only successful internally developed games nowadays are the EA Sports mega-franchises like Madden. Most of their success has stemmed from their ability to buy other companies on their way up, squeeze the creativity out of them, and then sell them to someone else or just let them go. This week they made their largest acquisition ever when they purchased PopCap Games for $750 million upfront—as m...
In the world of developers, a "sandbox game" is video game where players are free to "roam a virtual world and change any factor at will"; these types of games demand creativity on the player's part, with no linear/"correct" way to play.
Tower defense games have covered a lot of creative ground over the last five years. They've gone from simple desktop amusements to a staple of the indie game scene, having been integreated into nearly every other type of game and released on every platform. They have taken place in ancient times, the far future, and on alien planets. But one place they (and most other types of video games) have never taken place is the real world. Not a virtual recreation of the world, but on the very terra f...
Yale University has opened up its museum archives to the public in digital form, providing free online access to high-resolution images from its cultural collections, making it the first Ivy League school to do so in this fashion. Currently, there's over 250,000 "open access" images available from their new online collective catalog, with the goal of providing scholars, artists, students and all other worldly citizens royalty-free, no-license access to images of public domain collections with...
Have you ever heard symmetrical is sexier? Yep, according to scientists, symmetry is inherently more attractive to the Homo Sapien eye. Back in the days of Helen of Troy, Phidias, Plato and other great philosophers all observed the golden ratio, "a sum where the quantities to the larger quantity is equal to the ratio of the larger quantity to the smaller one". Confusing? Let's apply it to the human face only: the features of the human head were measured in calculated, precise proportions to d...
Always wanted a fluorescent dog but didn’t want to commit? Well, here’s your solution. Researchers at Seoul National University developed fluorescent puppies that only glow when you want them to. Just inject the special pups with doxycycline and they’ll glow like a black light poster for a few weeks. Then, they return to dull, furry normal.
Muay Boran Muay Boran (Ancient Boxing) is an all-inclusive term for the ancient boxing arts of Thailand, from which modern Muay Thai was born. In the old days, fighters would wrap their hands with strips of twisted hemp cloth or hemp rope. Although it is commonly thought that fighters would dip their wrapped hands in broken glass, this is largely a myth. They did, however, dip their hands in water in order to harden the rope.
Meanwhile, back in Marwencol, the SS took me, tied me up and started to cut me... The SS had me tied up. The girls went into the church. They eliminated the SS. Her coming and saving me proved to me that she loved me. So, this is my wife, Anna.
Do you have some "Fertilize All" bags that you'd like to use but perhaps: 1. You don't want to use it right when you plant because your neighbors won't have anything to fertilize when they stop by and therefore won't get the most Coins/ XP they can from their visit.
Tawkon has developed an app for the iPhone, Android, and Blackberry that measures the radiation levels at any given time. The demonstration below shows how the radiation levels go up for each phone when a "death grip" is applied. What's a death grip, you may ask? A death grip is a simple term used to denote a hand that has recently killed. What a troublesome thing to have.
In a recent survey of more than 5000 UK jobseekers by TotalJobs.com, it was found that 60% spend less than two hours working on each application following a job search, all inclusive of the time it takes to write a CV and covering letter, and to prepare for an interview.
And Dumbfounded Most Watching Game 1 of 2010 World Cup I just finished watching the Mexico - South Africa 2010 World Cup opener and boy was it a good one. The finish of a tie, wasn't totally cool to me, until I realized what I missed.
