Lurking behind Einstein’s theory of gravity and our modern understanding of particle physics is the deceptively simple idea of symmetry. But physicists are beginning to question whether focusing on symmetry is still as productive as it once was.

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.

Garbage collectors in the Turkish capital have opened a public library comprised entirely of books once destined for the landfills.
The library, located in the Çankaya district of Ankara, was founded after sanitation workers started collecting discarded books.
“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.
