The fractal geometry, makes reference to geometrical objects fractured, is a mathematical tool very powerful to represent in a computer and, with fidelity, structures that we can find, either in the nature or some things created by the man. Furthermore allows realize simulations more accurate of all kind of natural phenomenons. Also it's applied, in certain situations, to resolve all kind of problems. Would you like know how are made?

Have you ever tried to watch a Youtube high definition video with a slow computer? If you didn't try it, I tell you that, regardless the charge time, it's played slower than a lame and asthmatic turtle. However, if in that same computer, you download the video and play it with a good video player like VLC, you can see it perfectly. Do you want to know why? Follow reading "Why are the videos in Flash so slow?"

The processors aren't inmune to the radiactivity. This it produces soft errors, that are errors in the signals of its circuits, produced by the noise that generates the radiation on it. The consequences of the radiation over the machines aren't so devastating as over the human, because in the worst case we can reboot the machine, but the things that could do the machines affected by radiation to the humans, it could be dangerous. Deep in "The machines neither are inmune to the radiactivity"

The RSA is an encription algorithm of public key more used in the world. Its security increases exponentially with every bit that we add to the encription key, hence nobody have achieved break its security and maybe nobody do it never. If you want know how are posible the secure bank transactions over Internet, or how can be signed digitally e-mails and documents, besides of other things, follow reading. Read all about of "RSA: the security of your money depends of it"
