[VIDEO] Why Are Astronauts Weightless?

Why astronauts in the space station are weightless?The most common answer is because there is no gravity in space. But of course there is gravity in space, especially where the space station is located (only about 400km from Earth's surface).

What is the right answer?

10 New Ways Twitter Is Changing The College Lecture

10 New Ways Twitter Is Changing The College Lecture | COVEMET | Scoop.it

Continuing our theme of using Twitter in education this week, we bring you a look at the ways Twitter is causing the current lecture model to evolve. The following analysis is brought to you by our content partners over at Online Universities.

 

Gone is the time when PowerPoint was the most impressive communication technology in the lecture hall. These days, students and professors enjoy the power of Twitter, a tool that allows for digital discussions to supplement and even guide lecture sessions. So how exactly is Twitter changing the college lecture as we know it?

 

Read on to find out about 10 different ways.

 

- Mobile devices are welcome in the lecture hall once again

- Lectures become a conversation

- Bashful students are speaking up

- More students get connected in large lectures

- Students stay engaged beyond the lecture

- Dorm discussions don’t happen as much anymore, and that’s OK

- There’s more information saved now than ever before

- Students think about lectures even when they’re not at school

- Review sessions happen anywhere

- Fewer classroom disruptions exist

@Mariana, knowmads is a concept developed by wildcat2030 cobining the words knowledge and nomad. It comes to mean a nomad in the sphere of knowledge. You can find much more in the Polytopia Project in http://spacecollective.org/projects/Polytopia/

Volcán Kick’ Em Jenny en las aguas de Granada Isl. al Norte de Venezuela

Volcán Kick’ Em Jenny en las aguas de Granada Isl. al Norte de Venezuela | COVEMET | Scoop.it

El volcán activo mar cercano es el Kick’ Em Jenny pero se encuentra en las aguas de Granada al norte de Venezuela. El Kick’ Em Jenny es un volcán submarino.

Kick’ Em Jenny (Granada)

Kick’ Em Jenny es un volcán submarino localizado a 10 kilómetros al norte de la isla de Granada (12º 30’ N, 61º 3’ O). Es el volcán más al sur en el arco volcánico de las Antillas Menores y el único volcán submarino activo. Tiene un diámetro en la base de aproximadamente 5 Km. y se eleva 1300 metros por encima del piso oceánico. Su cima se ha levantado de 235 metros debajo de la superficie del mar en 1962 a 160 metros veinte años después. Su nivel actual (noviembre 2002) es de 130 metros. Los estudios oceanográficos han descubierto que existe un cráter en la cúspide del volcán y las muestras recuperadas de piroclásticos están principalmente compuestas de basalto y olivino.

La primera erupción conocida fue el 24 de julio de 1939 y fue presenciada por un gran número de personas en el norte de Granada. Esta erupción envió una nube negra a 270 m sobre el nivel del mar y generó una serie de olas del mar o tsunamis que tenían amplitudes de aproximadamente 2 metros en Granada del norte y las Granadinas del sur. Numerosas erupciones históricas han ocurrido desde 1939 siendo las más conocidas las de 1943, 1953, 1965, 1966, 1972, 1974, 1977, 1988 y 1990, siendo la más reciente en diciembre del año 2001. Durante la erupción de 1965, temblores de intensidad 5 se sintieron en la Isla de Ronde. Durante la erupción de 1974, el mar sobre el volcán estaba presentaba turbulencia y exhalaba vapor.

Consecuencias para Venezuela

Si bien este volcanes se encuentran localizados a buena distancia de nuestras costas, aún siguen representando una amenaza importante para los recursos pesqueros y político-territoriales con los que cuenta Venezuela en el Mar Caribe.

La amenaza principal son los sismos provocados por estes volcan, es que genera desplazamientos en la placa Caribe los cuales posteriormente se convierten en tsunamis o mares de leva los cuales ponen en peligro ciudades costeras como Cumaná, Puerto La Cruz, Barcelona, La Guaira y en especial el Estado Nueva Esparta. Igualmente, un tsunami de suficiente fuerza podría destruir por completo los puestos navales de observación ubicados en Isla de Aves y desencadenar un problema de índole político-territorial.

Una erupción de gran intensidad de alguno de estos volcanes quizás no afecte directamente al país, pero podría alterar significativamente el ecosistema marino y generar pérdidas importantes a la industria pesquera nacional.
