“claims to compress any input data by at least one bit”
“Now, suppose I compress 10 different files in this way — each of them compresses to a single ‘1’ or ‘0’ (a single bit).”
Why stop at a single bit? If it can compress any input by at least one bit, then it can compress an input of one bit into 0 bits. Infinite compression!
The cold plasma reactors are more often used in the last decades for diverse activities such as: the pollutant treatment from air or from solutions, plasti.
No matter how good your eyesight, there’s a decent chance that it’ll start to fade at a certain point in your life. Presbyopia is a common form of age-induced far-sightedness, where the lenses in the eyes become stiff and have trouble focusing on close-up objects. Now a Stanford team has developed a pair of high-tech specs called autofocals, which use fluid-filled lenses, depth-sensing cameras and eye-tracking technology to make sure whatever a wearer is looking at stays sharp.
The Division focuses on the detection of gravitational waves and the development of gravitational-wave astronomy. This comprises the development and operation of large gravitational-wave detectors on the ground as well as in space, but also a full range of supporting laboratory experiments in quantum optics and laser physics.
According to Einstein´s theory of General Relativity, accelerated masses produce gravitational waves – perturbations of spacetime propagating at the speed of light through the universe, unhindered by intervening mass. The direct observation of gravitational waves on September 14, 2015 added a new sense to our perception of the Universe.
In the future, we will for the first time listen to the Universe.

There’s egg on your face, literally. You tried to juggle some eggs, it all went wrong, and now you’ve got to shower and change your clothes.
Wouldn’t it be faster to just un-break the egg? Breaking it only took a few seconds, so why not do that again, but in reverse? Just reassemble the shell and throw the yolk and the white back inside. You’d have a clean face, clean clothes, and no yolk in your hair, like nothing ever happened.
Why don’t things happen in reverse all the time?
A team of researchers affiliated with several institutions in Spain and the U.S. has announced that they have discovered a new property of light—self-torque. In their paper published in the journal Science, the group describes how they happened to spot the new property and possible uses for it.
Scientists have long known about such properties of light as wavelength. More recently, researchers have found that light can also be twisted, a property called angular momentum. Beams with highly structured angular momentum are said to have orbital angular momentum (OAM), and are called vortex beams. They appear as a helix surrounding a common center, and when they strike a flat surface, they appear as doughnut-shaped. In this new effort, the researchers were working with OAM beams when they found the light behaving in a way that had never been seen before.
The experiments involved firing two lasers at a cloud of argon gas—doing so forced the beams to overlap, and they joined and were emitted as a single beam from the other side of the argon cloud. The result was a type of vortex beam. The researchers then wondered what would happen if the lasers had different orbital angular momentum and if they were slightly out of sync. This resulted in a beam that looked like a corkscrew with a gradually changing twist. And when the beam struck a flat surface, it looked like a crescent moon. The researchers noted that looked at another way, a single photon at the front of the beam was orbiting around its center more slowly than a photon at the back of the beam. The researchers promptly dubbed the new property self-torque—and not only is it a newly discovered property of light, it is also one that has never even been predicted.
