A system for generating electricity from the geomagnetic field and rotation of the earth is presented. The earth rotates through the geomagnetic field to form a potential difference between first and second terrestrial charged bodies. The first and second charged bodies are spaced apart in a direction substantially normal to the earth’s surface. The system comprises an electrical load, a first current path, and a second current path. The electrical load has a supply input and a ground output. The first current path is coupled to the first charged body and to the supply input of the electrical load, for supplying the potential difference to the electrical load. The second current path is coupled to the ground output of the electrical load and to the second charged body. As a result of this arrangement, an electric current related to the potential difference is generated in the electrical load.

“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!

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.
