Matter is the Stuff Around You

Matter is everything around you. Matter is anything made of atoms and molecules. Matter is anything that has amass. Matter is also related to light and electromagnetic radiation. Even though matter can be found all over the universe, you usually find it in just a few forms. As of 1995, scientists have identified fivestates of matter. They may discover one more by the time you get old. 

You should know about solids, liquids, gases, plasmas, and a new one called Bose-Einstein condensates. The first four have been around a long time. The scientists who worked with the Bose-Einstein condensate received a Nobel Prize for their work in 1995. But what makes a state of matter? It’s about the physical state of molecules and atoms.

23 de abril: DÍA INTERNACIONAL DEL LIBRO

20140423092022-20140422185249-dia-del-libro-2012.jpg

El Día Internacional del Libro es una conmemoración celebrada a nivel mundial con el objetivo de fomentar la lectura, la industria editorial y la protección de la propiedad intelectual por medio del derecho de autor.  

El día 23 de abril fue elegido como Día Internacional del Libro, pues coincide con el fallecimiento de Miguel de Cervantes, William Shakespeare y el Inca Garcilaso de la Vega en la misma fecha en el año 1616 (aunque realmente no es así: Cervantes falleció el 22 y fue enterrado el 23, mientras que Shakespeare murió el 23 de abril del calendario juliano, que corresponde al 3 de mayo del calendario gregoriano). En esta fecha también fallecieron William Wordsworth (en 1850) y Josep Pla (en 1981).

La Unión Internacional de Editores propuso esta fecha a la Unesco, con el objetivo de fomentar la cultura y la protección de la propiedad intelectual por medio del derecho de autor. La Conferencia General de la Unesco la aprobó en París el 15 de noviembre de 1995, por lo que a partir de dicha fecha el 23 de abril es el "Día Internacional del Libro y del Derecho de Autor".

1st conditional

IF + SUBJECT + PRESENT SIMPLE , SUBJECT + WILL + INFINITIVE

SUBJECT + WILL + INFINITIVE + IF + SUBJECT + PRESENT SIMPLE

We use the First Conditional to talk about future events that are likely to happen.

  • If we take John, he’ll be really pleased.
  • If you give me some money, I’ll pay you back tomorrow.
  • If they tell us they want it, we’ll have to give it to them.
  • If Mary comes, she’ll want to drive. 
The ’if’ clause can be used with different present forms.
  • If I go to New York again, I’ll buy you a souvenir from the Empire State Building.
  • If he’s feeling better, he’ll come.
  • If she hasn’t heard the bad news yet, I’ll tell her.

The "future clause" can contain ’going to’ or the future perfect as well as ’will’.

  • If I see him, I’m going to tell him exactly how angry I am.
  • If we don’t get the contract, we’ll have wasted a lot of time and money.

The "future clause" can also contain other modal verbs such as ’can’ and ’must’.

  • If you go to New York, you must have the cheesecake in Lindy’s.
  • If he comes, you can get a lift home with him.

22 de abril: DÍA DE LA TIERRA

20140422112821-images.jpg

Hoy la Madre Tierra es protagonista. Este martes 22 de abril se celebra el Día de la Tierra.

El 22 de abril de 1970 el político y activista ambiental Gaylord Nelson propuso la creación de una agencia medioambiental y su petición no cayó en saco roto. Se creó la Environmental Protection Agency (Agencia de Protección Ambiental) y una serie de leyes destinada a la protección del medio ambiente. Por eso cada 22 de abril se celebra en muchos países el Día Internacional de la Tierra.

El senador estadounidense luchó para que el mundo entero se concience de los problemas de la naturaleza, la contaminación y la necesidad de mantener la biodiversidad.

Este año, el Día de la Madre Tierra se centrará en las ciudades verdes, con el objetivo de movilizar a millones de personas para lograr un medio ambiente saludable y sostenible. «En la actualidad, más de la mitad de la población mundial vive en las ciudades. A medida que la población urbana crece y los efectos del cambio climático empeoran, nuestras ciudades deben evolucionar», según explica la ONU.

Animal Groups

Almost all animals fall into one of two groups. Adultvertebrates have a spinal column, or backbone, running the length of the body; invertebrates do not. Vertebrates are often larger and have more complex bodies than invertebrates. However, there are many more invertebrates than vertebrates.

Vertebrates

  • Fish breathe through gills, and live in water; most are cold-blooded and lay eggs (although sharks give birth to live young).
  • Amphibians are cold-blooded and live both on land (breathing with lungs) and in water (breathing through gills) at different times. Three types of amphibians are frogs and toads, salamanders, and caecilians. Caecilians are primitive amphibians that resemble earthworms. They are found in the tropics.
  • Reptiles are cold-blooded and breathe with lungs. They have scales, and most lay eggs. Reptiles include snakes, turtles and tortoises, crocodiles and alligators, and lizards. Dinosaurs were reptiles, although some scientists believe that some were warm blooded.
  • Birds are warm-blooded animals with feathers and wings. They lay eggs, and most can fly (although many, including penguins and ostriches, cannot).
  • Mammals are warm-blooded, and are nourished by their mothers’ milk; most are born live (however, the platypus lays eggs). Most mammals also have body hair.

Invertebrates

  • Sponges are the most primitive of animal groups. They live in water (usually saltwater), are sessile (do not move from place to place), and filter tiny organisms out of the water for food.
  • Coelenterates (jellyfish and polyps) are also very primitive. Their mouths, which take in food and get rid of waste, are surrounded by stinging tentacles. Some coelenterates are jellyfish, corals, and sea anemones.
  • Echinoderms include starfish, sea urchins, and sea cucumbers. They live in seawater and have external skeletons.
  • Annelids or worms come in many varieties and live in all sorts of habitats — from the bottom of the ocean to the inside of other animals. They include flatworms (flukes), roundworms (hookworms), segmented worms (earthworms), and rotifers (philodina).
  • Mollusks are soft-bodied animals, which often live in hard shells. They include snails, slugs, octopus, squid, mussels, oysters, clams, scallops, chitons, and cuttlefish. Mollusks are the second-largest group of invertebrates, with 50,000 living species.
  • Arthropods are the largest and most diverse of all animal groups. They have segmented bodies supported by a hard external skeleton (or exoskeleton). Arthropods include insects, arachnids (spiders and their relatives), centipedes, millipedes, and crustaceans like crabs, lobsters, and shrimp.
