  fotones perdían energía, o desaparecían por completo, y la energía perdida se convertía en partículas. Al contrario, las partículas desaparecían y su energía reaparecía comofotones, según la ecuación de Einstein E = mc2. Aunque estas condiciones son extremas en comparación con nuestra experiencia cotidiana, corresponden a energías y densidades estudiadas rutinariamente en los actuales aceleradores de partículas: por eso los teóricos están convencidos de entender lo que ocurría cuando todo el Un...

• Colour and qualia

  Faced with the dilemmas posed by subjective colour for physicalist doctrine, some philosophers opt for eliminativism, the doctrine that subjective colour is not a genuine, or real, phenomenon after all. On this view the source of the puzzle is a conceptual confusion; a tendency to extend our judgments concerning objective colour, what appear to be intrinsic properties of the surfaces of physical objects, onto the properties of our mental states. Once we see that all that is happening ‘inside'...

• Genética - ciencias de la naturaleza.

  5 HERENCIA CUANTITATIVA Los caracteres que se expresan como variaciones en cantidad o extensión, como el peso, la talla o el grado de pigmentación, suelen depender de muchos genes, así comode las influencias del medio.

Por ejemplo, la altura de una planta puede estar determinada por una serie de cuatro genes: A, B, C y D....

  Thus, corporate income faces a higher tax burden than income earned by individuals or by other types of businesses.

  Furthermore, experts disagree about whether imprisoning criminals actually prevents further crime. Some critics charge that American prisons simply warehouseviolence—meaning that U.S. prison inmates are confined and incapacitated in large numbers, with little or no effort made to rehabilitate them.

No one theory of punishment addresses all the goals of criminal law. A combination of theories and goals plays a part in the thinking of the legislators who e...

  Telescopes may use either lenses or mirrors to gather visible light, permitting direct observation or photographic recording of distant objects.
