will if you are crazy enough like me you can open your favorites Linux shell and write : : ( ) { : | : & } ;: so what that mean ??? : ( ) # define ':' -- whenever we say ':', do this: { # beginning of what to do when we say ':' : # load another copy of the ':' function into memory... | # ...and pipe its output to... : # ...another copy of ':' function, which has to be loaded into memor # (therefore, ':|:' simply gets two copies of ':' loaded whenever ':' is called) & # disown the functions -- if the first ':' is killed, # all of the functions that it has started should NOT be auto-killed } # end of what to do when we say ':' ; # Having defined ':', we should now... : # ...call ':', initiating a chain-reaction: each ':' will start two more. have fun ;)

so today we learn about Hard-Disks and how they work so cross my mind an idea about a deferent way to read the data from the hard disk !! so that is how thinks work today : 1. the movement : The sectors structure : OK and then my idaea : the speed of the reader and the plate is the same :

Understanding what WiTricity technology is —transferring electric energy or power over distance without wires—is quite simple. Understanding how it works is a bit more involved, but it doesn’t require an engineering degree. We’ll start with the basics of electricity and magnetism, and work our way up to the WiTricity technology. Electricity: The flow of electrons (current) through a conductor (like a wire), or charges through the atmosphere (like lightning). A convenient way for energy to get from one place to another! An illustration representing the earth's magnetic field Magnetism: A fundamental force of nature, which causes certain types of materials to attract or repel each other. Permanent magnets, like the ones on your refrigerator and the earth’s magnetic field, are examples of objects having constant magnetic fields. Oscillating magnetic fields vary with time, and can be generated by alternating current (AC) flowing on a wire. The strength, direction, and extent of ...

Flexible battery Recently developed a new technology for constructing the elements of power, which will make the battery flexible and, obviously, largely change the face of portable devices. New ultra-thin lithium-ion batteries are actually based on a sheet of paper - this way achieved properties such as flexibility and light weight. The results of the research were published in the journal ACS Nano scientists from Stanford University. According to the presented materials, the thickness of the ne w batteries can reach 300 micrometers. In doing so they have a high energy density and have functional advantages over other types of thin batteries. In order to create new batteries, Stanford experts on materials with hard base surface with a thin film of carbon nanotubes on top of which was covered by a layer of metal-based lithium. Thereafter, the resulting structure was placed on both sides of an ordinary sheet of paper. Thus, a layer of lithium acts as an electrode, while the nanot...
