What actually happens if you sit in front of a laboratory particle beam accelerator? Well, you can try and find out, but I would suggest to have a look at this video first, which graphically ilustrates what happens. Very insightful. Also, you should keep in mind that these kind of particles are seen regularly in space. An effective way of dealing with them (using electromagnets) has been proposed, but is still in research. Enjoy!
Transparent plastic and some tape..that's all it took the scientists to invent a coffee cup that works in zero gravity. Yay!
The extreme test consists in dropping an egg from the top of a 22m (72ft) building. The shock absorbing gel awaits the egg at the bottom. This gel has been used for some time now in running shoes, to dampen the shocks. Really cool!
I remember chemistry class as very boring and with all kinds of formulas that made me fall asleep. Well...at the Ontario Science Center, kids can take passion in chemistry by watching a cool show. Here it is on video, one part of that show!
Who would've thought shampoo could me so much fun? Scientists of the University of Twente made a video of leaping shampoo. This is actually a fluid effect called Kaye effect. Some fluids in motion can manifest this interesting effect. I don't know about the practical applications of it, but it's very beautiful! Enjoy!
Fero-magnetic fluid is the stuff that Ferrari makes its car suspensions from. It's a fluid containing iron particles. When an electromagnetic force is applied to it, it tends to shape itself to the wave lines of the electromagnetic field. You can try something similar at home with some iron shavings on a plate, and a magnet underneath the plate. It's used in car suspensions because it can modify the stiffness of the ride almost instantly.
Her's another use for fero-magnetic fluid, this time with beauty in mind, and less practical. Enjoy it!
This little piggy ain't there? This mirror illusion is created utilizing two parabolic mirrors. The effect is astounding, creating something similar to a hologram because the toy seems to be there, but it actually isn't. Pretty cool mirror illusion.
Some clips of Thermite from Brainiac science abuse. Thermite burns at around 4000 °F (2500 °C) and can cut just about anything. Watch it destroy anything in its path! Cool.
A non-newtonian fluid under stress reacts as a solid. In this case they filled a pool with a mix of cornstarch and water made on a concrete mixer truck. It becomes a non-newtonian fluid.
Update: Liquid Armor is one of this fluid's applications.
Funny
A crazy and very funny video showing you a very scientific way in determining the height of a building. I don't know what's the deal with the contamination suits, so don't ask
Here's a funny explanation (true nevertheless) about the size of the Universe. The lecture is held by the internationally known Yakko from Animaniacs. Have phun, and enjoy!
Tech
I'm all against animal cruelty and such, but sometimes, these experiments can bring forward something that would benefit millions of people. I think that one such case is this. This monkey has a microchip implanted in its brain, and linked up to a robotic arm. The amazing thing is that the monkey can control the arm like an extension of its body, with incredible precision, and without any visible effort!
Cool experiment using an egg and a candle. The result is that you can see the inside of the egg just like an X-Ray (without the radiation
An awesome video of a sound resonance experiment. By raising the wavelength of the sound beautiful patterns (and more complex) appear in the powder. Just another demonstration that physics can be beautiful
Amazing
This little transformer can morph from a Humvee into a robot in a few seconds. Of course, there's not much future for it in real life, but it's freakin awesome to make as a science project!
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!
It's an interesting experiment. I'm not completely sure it's not a fake, but it's easy enough to try at home., so you should give it a try, and let me know how it works!
Although it isn't the best at it, and that it may have some concentration problems, it's clear that the chimp understants to some degree the goal and rules of the game. It's quite amazing!
Technology and Health News
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."
