Hacia donde vá la computación?
Si quisiéramos resumir el estado actual de la computación, diríamos que está basada en la combinación a ultranza de 0s y 1s, hacia atrás, hacia adelante, hacia arriba y hacia abajo, pero en un solo plano, al modo como trabajaba la geometría euclidiana (ver esquema de la izquierda). No obstante y, con solo eso, es posible ver : fotos, animaciones, dibujos, pinturas, fotos, escuchar variados sonidos,denostar de nuestro presidente y disfrutar de la lectura de los bitacoristas de nuestro agrado. Macanudo,verdad?.
Pero lo real es que si a tu ordenador actual, le pides que factorice o, busque cierta información al azar, no archivada convencionalmente, se demorará una eternidad. Si insistes y le solicitas amablemente que determine la mejor elección, entre varias posibilidades, tendrás que premunirte de gran paciencia, porque la máquina "puede loquearse".
Los ordenadores actuales, enfrentan problemas a- de diseño, no disponen por ejemplo de los sutiles y sofisticados circuitos en paralelo, que permiten desviar, bypassear, procesar y adquirir información en poco espacio, como lo hace el cerebro humano y b-de espacio, porque ciertos ordenadores (supercomputadoras), que si pueden resolver algunos de los problemas señalados anteriormente, necesitan extensos espacios, evento impráctico e impensable, en tanto la tendencia es a aminorar el tamaño, por razones de mercantilismo y de accesibilidad hacia todos los seres humanos.
En tal virtud, la tendencia vigente es a reducir más y más el tamaño de los transistores y por ende de las unidades de computación (bits). El menor tamaño de un transistor actual es de un 1/4 de micrón, cada véz más cerca del tamaño de moléculas inorgánicas. Por lo tanto hoy se piensa en reemplazar, ceros y unos por :moléculas, átomos o, electrones (computación cuántica). En este caso la alegoría estaría representada por una esfera (como la de la derecha, reducida en tamaño a 0.000 000 0001 nm), en la que una unidad de información :qubit¨= un electrón (0), inactivo, puesto en actividad (1), por rayos láser, partiendo del centro, en forma de onda con las alas desplegadas (no como simple punto), avanzaría hacia afuera con miles de posibilidades, siguiendo múltiples direcciones, pudiendo también interconectarse con otras ondas (más qubits), simultáneamente. Ya no hay planos, solo espacios topológicos, semejantes a los fisico-matemáticos de Riemann.
Estamos hablando entonces, de una computación de vasto alcance. El británico Roger Penrose piensa que algo de esta perspectiva debe premunir también, al funcionamiento cerebral. A este nivel (electrónico), la fisica predecible ya no funciona y en lugar de ver al 0 y al 1, en forma independiente, no los podremos distinguir, el 1, será :1 y 0 a la véz. Solo hablaremos de probabilidades de localización, velocidad y carga energética de los qubits. Cuando se resuelvan algunos problemas de la computación cuántica como : escalabilidad (incremento definido in crescendo de qubits), sostenimiento de la coherencia cuántica a lo largo de los procesos, iniciación controlada y coneccion permanente de los procesos a redes mundiales, entonces encontraremos en nanosegundos, la tarjeta no marcada y el mejor camino a seguir.
Al lado de esta opción, existe otra, la de realizar operaciones informáticas empleando el modelo que usa la naturaleza, para memorizar y reproducir los esquemas corporales de plantas, animales y seres humanos : combinación ad infinitum de 4 letras :adenina (A), timina (T), citosina (C) y guanina (G), como sucede en el DNA y RNA orgánico. Estas letras, tampoco ocupan mucho espacio: simplemente se enrrollan entre sí en forma de finos filamentos.

Towards where goes the computation?
If we wanted to summarize the present state of the computation, we would say that it is based on the combination at any cost of 0s and 1s, backwards, forwards, upwards and downwards, but in a single plane, to the way as euclidian geometry worked (see :scheme of the left). Despite and, with single that, it is possible to see: pictures, animations, drawings, paintings, designs, to listen varied sounds, to revile our president and to enjoy the reading of the bloggers of our affability. Very good, right?.
But the real thing is that if you request to your present computer, that factorice or, looks for certain information at random, not filed conventionally, it will be delayed an eternity. If you insist and solicit him amiably that it determines the best election, between several possibilities, you must have great patience, because the machine "can be crazy".
The present computers, face problems of design, do not have for example the subtle and sophisticated circuits in parallel, that allow to turn aside, bypass, process and to acquire data in little space, like it makes the human brain and b-of space, because certain computers (supercomputers), that can solve previously indicated problems, need extensive spaces, an event impráctic and unthinkable, in as much the tendency is to lessen the size, for public accessibility and mercantilistics reasons.
In such virtue, the tendency is to reduce more and more the transistors size and therefore of the units of computation (bits). The minor size of a present transistor is : 1/4 of micron, very near the size of inorganic molecules. Therefore today one thinks about replacing, zeros and ones by : moléculas, atoms or, electrons (quantum computation). In this case the allegory would be represented by a sphere (like the one of the right, reduced in size to 0,000 000 0001 nm), in which a information unit : one qubit=one inactive (0) electron, activated by laser beam, starting off of the center, in waveform :active electron (1), with the unfolded wings (not like simple point), would advance outwards with thousand of possibilities, following multiple directions, also being able of interconnecting itself with other waves (more qubits), simultaneously. No longer there are planes, instead we will have topológical, similar spaces to the physical-mathematicians of Riemann.
We are speaking then, of a computation of vast reach. The Briton Roger Penrose thinks that something of this perspective must also have the brain. At this level (electronic), the predictable classic physics, no longer works and instead of seeing the 0 and the 1, in independent form, we will not be able to distinguish them, 1 will be 1 and 0, at the same time. Single we will speak of probabilities of location, speed and power load of qubits. When some problems of the quantum computation were solved like: scalability (increase defined, in crescendo of qubits), support of the quantum coherence throughout the processes, controlled initiation and coneccion permanent of the processes to world-wide networks, then we will find in nanoseconds the marked card and the best way to follow.
Next to this option, it exists another one, the one to conduct computer science operations using the model that employs the nature, to memorize and to reproduce the corporal schemes of plants, animals and human beings: : combination ad infinitum of 4 letters :adenine (A), timine (T), citosine (C) and guanine (G), as it happens in organic DNA and RNA. These letters, do not occupy much space either: simply they are rolled up to each other in fine filament forms.

Te felicito, es de lejos el mejor blogger peruano que conozco hasta ahora. Muchos temas quizas no los entiende la mayoria pero si que es superinteresante. Siempre me fascino la idea que ninguna computadora pudiera siquiera hacer lo que hace una mosca eso es debido a que la computacion siguio los lineamientos de Von Neumann, pero creo que ahora hay una mayor tendencia a explorar el comportamiento de las celulas cerebrales y el campo llamado Cellular Automata.Lo del tema de la memoria es superinteresante porque la naturaleza almacena mejor la informacion y lo hace de una manera distribuida asi mas o menos como lo hace Goggle no almacena sus datosen un solo lugar sino topologicamente en diferentes nodos de la red. Sumamente Interesante tu blog. Felicitaciones otra vez soy tu mas asidua lectora.

Gracias desde el fondo de mi corazón, Litta, por el apoyo moral.
Si te place saberlo, te diré un secreto, no escribo con la mente lo hago con el corazón,un abrazo:vmechanm.
Excellent, love it! »

Everything typed made a great deal of sense. However, consider this, suppose you were to create a awesome headline?
I ain't saying your content is not good, but what if you added something to maybe grab folk's attention?
I mean "Hacia donde v� la computaci�n?" is a little boring.
You could glance at Yahoo's home page and watch how they create article headlines to get viewers to open the links. You might add a related video or a related picture or two to grab people interested about everything've written.
Just my opinion, it would bring your posts a little bit more interesting.
Visit my web blog :: mc9060
First off I want to say great blog! I had a quick question which I'd like to ask if you don't
mind. I was interested to find out how you center
yourself and clear your thoughts prior to writing. I
have had trouble clearing my thoughts in getting my ideas out.
I do take pleasure in writing however it just seems like the first 10 to 15 minutes are wasted simply just trying to figure out
how to begin. Any recommendations or hints? Many thanks!
