!Mira que luna! Look at that moon! Resources for learning English
Fernando Olivera: El rapto.- TEXT FROM THE NOVEL The goldfinch by Donna Tartt (...) One night we were in San Antonio, and I was having a bit of a melt-down, wanting my own room, you know, my dog, my own bed, and Daddy lifted me up on the fairgrounds and told me to look at the moon. When "you feel homesick", he said, just look up. Because the moon is the same wherever you go". So after he died, and I had to go to Aunt Bess -I mean, even now, in the city, when I see a full moon, it's like he's telling me not to look back or feel sad about things, that home is wherever I am. She kissed me on the nose. Or where you are, puppy. The center of my earth is you". The goldfinch Donna Tartt 4441 English edition

  • IN THE world of particle physics, there is no such thing as nothing. Particles of matter, and their anti-matter counterparts, are forever flitting in and out of existence. Theorists have predicted that the presence of such transient visitors has little effect on everyday life. However, a group of experimental physicists has just shown this view to be mistaken.
  • Atomic nuclei are bundles of protons and neutrons which, along with electrons, are the basis of matter. But protons and neutrons themselves are made of more fundamental particles called quarks. These quarks have fractional electrical charges and combine to give each particle its overall electric charge, whether positive in the case of protons or neutral in the case of neutrons. They also give each particle its magnetic properties.
