I love Wikipedia. In fact, I spend about an hour each day surfing through random articles of things I know little about and find interesting. If I run into something I have no idea about, I make a mental note to Wikipedia-it as soon as I can.  I use Wikipedia more than I use Google and maybe as much as Facebook.</p>
<p>The other day, while pillaging information from Wiki, I stumbled upon an article- <em><a href="http://en.wikipedia.org/wiki/Six_degrees_of_separation">Six Degrees of Separation</a></em>. According to the article:</p>
<blockquote><p><em><strong>Six degrees of separation</strong></em> (also referred to as the &#8220;Human Web&#8221;) refers to the idea that, if a person is one step away from each person they know and two steps away from each person who is known by one of the people they know, then everyone is at most six steps away from any other person on Earth.</p></blockquote>
<p>Being the semi-nerd that I am, I was immediately fascinated with this idea. No matter how big the world is, in theory, you are only six degrees of separation from another certain person in the world. I Guess this backs up the old saying, “it’s a small world.”</p>
<p>Moreover, this reminded me of the physics concepts of action at a distance and non-locality. The Copenhagen Interpretation asserts that quantum mechanic systems violate the locality principle (i.e. that distant objects cannot have direct influence on one another: an object is influenced directly only by its immediate surroundings). In fact, experiments have shown that entangled quantum states do violate said principle, as entangled states collapse simultaneously upon measurement of one of their entangled components, regardless of the spatial distance between the two states. Gosh, that is a mouthful. Basically, non-locality allows for instantaneous action at a distance: the interaction of two objects which are separated by a space (it could be as large as half the universe or larger!) with no known arbitrator of the interaction. Einstein had a fit because it meant faster than light communication, violating special relativity! Einstein never really liked quantum mechanics anyway but the theory remains very powerful and useful today.</p>
<p>This leads me to think that the interaction of two individuals separated by a distance could be true even if those individuals are unaware of the interaction. Only six degrees of separation (at most) from any other human being that you don’t know? Wow. It would be neat if love could be the interaction. Is it possible that two minds are linked from the moment they are born, and no matter the distance one feels what the other feels? When they meet, do they share the bond of love? If it works for electrons in the same atomic system then it can work for us! <img src='http://www.oscarnuno.com/wp-includes/images/smilies/icon_wink.gif' alt=';)' class='wp-smiley' /> </p>

<p>Today, while holding my Blackberry during lunchtime, my mind drifted. What I was wondering was if my Blackberry actually &#8220;touched&#8221; my hand as it laid on it. My brain told me it was touching my hand, and the brain was relayed this information by Merkel cells, Meissner&#8217;s corpuscles, and possibly Pacinian corpuscles. I think there is one more Mechanoreceptor but I don&#8217;t remember which right now. So, my brain was detecting light touch, but was I really holding the Blackberry?</p>
<p>If we could zoom in to the atomic level, the atoms composing the Blackberry and the atoms composing my hand, will they be &#8220;touching&#8221;? I do not think so, as the electrons from hand and phone would repel, there is electromagnetic repulsion among the electrons. Atoms cannot really touch even when they &#8220;collide&#8221;. Also, there is no chemical reaction occuring between my hand and phone. Gravity is pulling the phone down into my hand, and according to Newton&#8217;s Third Law, the phone is pushing into my hand, therefore, my hand presses equally and opposite into the phone. However, at the atomic level, classical physics breaks down and gravity no longer works, making the case that I cannot hold the phone. Biology tells me I was holding my phone, whereas Quantum physics tells me I could never touch it. What should I believe? What might bake your noodle later is&#8230; what if the phone is holding me? <img src='http://www.oscarnuno.com/wp-includes/images/smilies/icon_biggrin.gif' alt=':D' class='wp-smiley' /> </p>

			<content:encoded><![CDATA[<p><img class="alignnone size-full wp-image-96" title="Fission" src="http://www.oscarnuno.com/wp-content/uploads/2009/03/fission.jpg" alt="Fission" width="270" height="206" /></p>
<p>Solo quería tomar unos minutos para informarles sobre algo. Voy a la Universidad y estoy estudiando pre-medicina, así que ya he tomado mucha biología, química, y física. Mi español le puede sonar erróneo, pero esto es debido a que tengo toda mi vida en Estados Unidos y nunca tome clases para escribirlo. Sin embargo, lo que le voy a presentar no tiene nada de erróneo porque esta basado a prueba de muchos Físicos y Químicos (muchos ganadores de premio Nobel) y esta verificado por el resto del mundo.<br />
Si empezamos desde el principio, en 1901 Max Planck seguido por Albert Einstein,<br />
descubrieron que la energía viaja en partículas pequeñas. Ernest Rutherford y Niels Bohr después concretaron como eran los átomos, una carga positiva en el centro (protón), y una carga negativa girando en orbita alrededor del protón a casi la velocidad luz. En los 1930s, James Chadwick descubrió la tercera parte importante de los átomos, los neutrones que tienen masa pero no carga eléctrica. En suma, todos los elementos tienen las tres cosas, el protón (cuyo junto el neutrón forman la masa), el electrón, y el neutrón. Protones y neutrones siempre están juntos (la excepción es hidrogeno) en todos los elementos.<br />
La Física atómica avanzo en pasos gigantes gracias a hombres como Paul Dirac, Werner Heisenberg, Erwin Schrodinger, Enrico Fermi…etc. (Todos ganadores de Nobel). Este ultimo, Fermi, un Italiano, y su equipo usaron ciclotrones (aceleradores de partículas, por ejemplo, protones y neutrones) para bombardear Uranio (92) que es el ultimo elemento en la tabla periódica que ocurre naturalmente, y notaron que al hacer esto surgían nuevos elementos transuránicos. Esto fue debido a que el núcleo de Uranio atrapo un protón cuando iba pasando o capturo un neutrón que se transmuto en protón, y esto, como lo saben, cambia el número atómico y es otro elemento mas arriba de posición en la tabla.<br />
Si tuviéramos un ciclotrón para bombardear, por ejemplo, a Iridio, pudiéramos obtener Platino, y si tuviéramos Platino lo pudiéramos convertir en Oro. Claro, que el Platino es mas caro que el oro, y el Iridio es muy difícil de obtener, ¡asi que hacerse uno rico de esta manera no es eficaz (aunque posible, no es eficaz)! Tal vez, ustedes están en su mente diciendo que de todos modos eso no es posible, pero ya hicieron los experimentos y los átomos de los elementos si pueden cambiar si les ponemos más protones o los podemos partir en elementos más bajos en la tabla, o de menor número atómico. Por eso ya tenemos muchos elementos como Americio y Plutonio, que son sintéticos.<br />
Si me permiten elaborar en lo que acaba de decir, de partir los átomos. En 1939, Otto Hahn, Lise Meitner, y Otto Frisch descubrieron que neutrones eran capables de partir los elementos. Hahn, bombardeo Uranio (92) con puros neutrones y esto causo que este elemento se quebrara en 2 elementos mas abajo en la tabla periódica, Bario (56) y Kriptón (36). Ósea, [U (92)+ neutrón-----> Ba (56) + Kr (36)] note que la suma es el numero de protones de Uranio. Al partir el Uranio, se libera mucha energía debido a que neutrones parten átomos y estos átomos partidos sueltan más neutrones que vuelven a partir más átomos y así causan Fisión (fission), y una reacción en cadena. Por eso, pudimos obtener bombas atómicas y energía nuclear. Todo esto que les cuento es espectacular y muy interesante, pero para muchos, esto no se lo pueden imaginar y suena imposible, sin embargo, si uno tiene la mente abierta y tiene deseo de aprender, lo puede comprender. Todo lo que escribí no fue de una página de internet sino de libros escritos por estos mismos ganadores de Premio Nobel que descubrieron todo eso. Esta todo comprobado, y los invito a investigar que todo lo que dije es correcto. ¡Pueden empezar con los nombres de las personas que mencione! Gracias por su tiempo y suerte en sus metas.</p>
