Queen's Bohemian Rhapsody played on old computer & electronics equipment. 'nuff said, right? Sit back & enjoy!

This little robot (device) can hold in place in equilibrium a pendulum. When the guy gives the pendulum a nudge, the robot automatically adjusts for it so it doesn't fall. Really cool!

I love this stuff. It's very ingenious, and what's especially tricky is the handling of the cube by the computer. So you got to admire the ingenious idea this guy had of doing it. Rather brutal, but it works! Cool!

Here's the ultimate overclocking PC. You submerge everything except the hard disk in mineral oil. For visual effect, you put in with it a blue neon light, and of course, some bubbles. It has an amazing look, and I suspect that it's dead silent.

A cool video animation showing what parts an engine is made of, and how it's put together. If you're a motor freak (like me) I'm sure you'll love it. Enjoy!

Here is a hilarious video material from a local TV station probably from some while back on how to clean and maintain your computer's mouse, and properly clean its ...ahem...balls. I really don't think this was a joke for them, as they don't even smile for one moment. Enjoy the hilariousness!

If you're a computer geek (like me) than you'll truly appreciate this commercial, and even think it's hilarious. If not (and congratulations, btw) you'll find amusing the fact that people are willing to invest so much in their PC. Either way, enjoy this funny video!

This guy's name is Harold Gomez and he's comedian. When I saw this clip it just cracked me up...I need a pop-up blocker. ROTFL. =))

Here's an extremely realistic water simulation (the most accurate I've seen so far actually) which will take gaming into a new age of realism. You'll probably need a physics acceleration card for it, but with that kind of realism, who cares?

A guy, with lots of spare time on his hands decided to make a graffiti machine. It's actually similar to a plotter printer. It can draw by a system of pulleys which coordonated by the computer make the graffiti machine draw each point of the original image on the wall. Nice.

It's not new that the brain works in some mysterious ways, and as time passes we're getting closer and closer to understanding what makes it tick. It defines who we are, and it's what separates us from the rest of the animal world. But this "super-computer" can sometimes misfire, and make false assumptions, simply because it hasn't got enough information or because 90% of the time the respective supposition is correct!

Well, if all the maneuvers done in an air show look simple to perform on a computer airplane simulator, there's another factor that you forgot: the extreme g-forces acting on the pilots body. Here's a video with a French pilot training on a Mirage 2000 fighter for an upcoming show. Besides the cool maneuvers you can actually feel the pain in his breething!

It's truly a breathtaking view. It's probably only used in movies for now, but if it will make it to the computer games industry, it would truly represent a revolution! Wow!

Computer geek or no computer geek, it's really hard to concentrate with those things in your face. God Damn! What was I talking about?

Small robots that walk on water like insects? The kitchen table, the walls of a room or the arms of an armchair that are self-cleaning? Two phenomena that Xiao Cheng Zeng, a professor of chemistry at University of Nebraska in Lincoln (USA), considers possible in the near future, and based on the same characteristic: super hidrofobia. Thanks to the computational performance of the super computer of the Riken Institute in Japan, the researcher is able to reproduce the conditions that give the area the property is to "roll" away the drops of water. In nature this phenomenon is observed on the bristles of caterpillars or on lotus flowers, and allows insects that often are seen on ponds slip skate on water. As the authors of the study reported the caterpillars or insects skaters get the super hydrophobia surface through a "two-tier" surface which means a waxy base on which there are microscopic structures like hair, often covered in turn by smaller "hair". These gradients decrease the surface area in contact with the drop of water. The result is that the drop rolls instead of sliding, as it would be a hydrophobic surface.

The new devices can operate at 30 degrees above zero, rather than less than 70. This is the characteristic of the new generation of semiconductors, researched at the Italian Institute for the Physics of Matter (INFM-CNR), and in the Ludwig Maximilian University in Monaco of Bavaria and the ETH Zurich (the study). Today there are two ways to record information on a medium: the electronic format, in which the binary language is the passage of electrons (the transistors) and magnetic (MRAM memory), more recently, in which the binary language is given by state of magnetization. To communicate these two systems could boost significantly the computational schemes, pending the distant quantum computer. Doubling the processing power and memory of a chip while maintaining the size, without the need to go in nano-scale (a scale, that is, a billionth of a meter) are just two of the technology that promises magnetic semiconductors suggest a near future. These devices were made over ten years ago, but so far required temperatures far below zero to work. The problem now seems outdated as the known semiconductors gallium arsenide containing traces of manganese, a metal which has ferromagnetic properties at around 200 degrees below zero. To increase the temperature threshold, above which the ferromagnetic behavior disappears, the researchers deposited on a semiconductor film of iron - metal known for its magnetic properties - the thickness of a few nanometers. Iron and manganese interacted so effectively that the new material, has a ferromagnetic behavior up to 30 degrees above zero, a jump of over a hundred degrees above the starting temperature. This result is a technological response parallel to that of the race to miniaturization and the research was selected the American Physical Society as one of the most important published in Physical Review Letters

A new instrument to simultaneously measure the magnetic field and the atomic structure of matter at the nanoscale has been developed. The applications of this are future generations of high-density memories Snapshots of the weakest and microscopic magnetic fields generated by just a few molecules of a nanometer (billionth of a meter). The researchers have obtained the S3 Center of the National Institute for the Physics of Matter (INFM-CNR) of Modena and the University of Modena . This is a scanning microscope combined with a new highly sensitive magnetic sensor. The microscope scans close with his point - made up of a few atoms - the area of the test and how it relates to the roughness with a resolution of several nanometers. Beside the point, the sensor records the magnetic field intensity, but with high detail ( millionth of a meter). In this way the researchers were able to get together for the first time, images of atomic structure and magnetic properties of a thin layer of nano-magnet on a support of silicon. "The microscope allows us to measure directly the properties of nano-molecular magnets on the surface, even at temperatures close to absolute zero, to minus 270 degrees," says Marco. "Above all," says the researcher, "it helps us to understand the magnetism on the molecular scale."

The switch that turns off and on to command the superconducting property of the new device is a trivial electric field. In practice, what has been done by Andrea Ankle and colleagues at the University of Geneva in the first superconducting transistors. The operation, represents a milestone of applied physics and paves the way for the development of a new generation of microchips - and therefore computers - much faster than at present. To understand how and why the device is considered so promising it must be from another discovery, made last year by the same group of university research in Switzerland and published in Science. In one study, physicists have created a single crystal in which two metal oxides (strontium titanate and lanthanum aluminate) are separated. Between these two materials, researchers have found a layer of free electrons (electronic cloud) and 0.3 Kelvin - that is just above absolute zero - traveling without any resistance. At that temperature, the crystal becomes a superconductor. Scientists have now discovered how to turn off and turn on the superconductivity of this crystal at will, or modules, simply by applying an electric field to the point of contact between the two oxides. The result is a version of superconductive field effect transistors (FET) devices known in applied physics, able to switch from one state to a semiconductor insulator, and basic digital information in electronics (the fact that the current can pass or not is used as a binary 1-0 to store information). As the field effect transistors is a semiconductor, however, it always has resistance to the passage of current. This means that the speed at which you can get the electrons when the device is "on" is limited which means heat develops beyond a certain limit. This side effect is damaging the transistor. A superconducting transistor, however, can pass electrons (and record information) much more quickly, as it does not oppose any resistance to the passage of current and, therefore, not heat. There remains the problem of extremely low temperatures required for superconductivity. A limit that research is a long time trying to overcome.

The sense of justice and the practical idea of efficiency are encoded in different ways and in different areas of the brain. A study in Science. Giving a lot to very few, or just a little at everyone? According to a study published on this number of Science, most people follow the second choice, relying on fairness. The neurophysiologists at the University of Illinois and California Institute of Technology have succeeded, through magnetic resonance imaging, to identify which brain areas are involved in taking such decisions. Scientists have concluded that two different parts of the brain, the insula (a small area of bark MEP to the perception of physiological states) and the putamen (Part nuclei that control voluntary movement), are activated when judging respectively fairness and efficiency. A third area, the caudate nucleus, is the coordination of the first two areas.
