Historians love to debate each other. So some of them pointed out that the first half of this revolution looks a lot different from the second. Let's chat about industry, cars, and Henry Ford.

Hank introduces us to the "simplest" of the animals, complexity-wise: beginning with sponges (whose very inclusion in the list as "animals" has been called into question because they are so simple) and finishing with the most complex molluscs, octopuses and squid. We differentiate them by the number of tissue layers they have, and by the complexity of those layers.

Irene Villa ha sabido convertir la adversidad en el motor impulsor de su vida. Tal como afirma, “la clave a veces está en cambiar el foco a la situación”. En su mensaje positivo, destaca valores como el optimismo, la fe en uno mismo, la determinación, el trabajo en equipo y el perdón. De este último asegura que “es la base para tener una vida plena y feliz”. Y añade que “el odio, la frustración y la autocompasión no sirven de nada, porque no te permiten crecer”. En este vídeo, Irene Villa reflexiona sobre la importancia de la aceptación, la autoestima y la fuerza de voluntad como claves para enfrentarse a los reveses de la vida.

Su historia conmocionó a España y al mundo. En 1991, un atentado con bomba cambió por completo la vida de Irene Villa. Con doce años perdió las dos piernas y tres dedos de una mano. Pero no perdió las ganas de luchar y se aferró a la vida con más fuerza que nunca. Su ilusión por la vida, su afán de superación y su pensamiento positivo la han llevado a convertirse en un ejemplo digno de admiración. En la actualidad es psicóloga, periodista, escritora y madre de tres hijos. También integra el equipo de competición de esquí adaptado de la ‘Fundación También’, donde ha conseguido varias medallas. Ha recibido innumerables galardones, tanto nacionales como internacionales. Es fundadora y presidenta de la Fundación Irene Villa, dedicada a la inclusión laboral y el deporte adaptado para personas con discapacidad. En 2013 fue elegida una de las ‘Top 100 Mujeres Líderes’ más influyentes de España.

En este vídeo, Gregorio Luri destaca la importancia de la lectura y la literatura como parte de la formación esencial de las personas desde la infancia. Según el filósofo y pedagogo, “aprender a leer es la tarea de una vida”. Y añade, “la lectura nos permite participar en el diálogo que mantienen entre sí las grandes mentes de nuestra cultura”. Gregorio Luri defiende que una buena lectura debe constituir, de vez en cuando, un reto para el lector, ya que esto le ayuda a mejorar su vocabulario y a hacer una reflexión más profunda sobre lo leído.

“Maestro de escuela” es el atributo que mejor define a Gregorio Luri. Obtuvo el Premio Extraordinario en la Licenciatura en Ciencias de la Educación y también en el Doctorado en Filosofía. Ha trabajado como maestro de primaria, como profesor de filosofía en bachillerato y como docente universitario. Trabaja como columnista en varios diarios y ha publicado más de una veintena de libros sobre filosofía, historia y educación.

As more and more fossil ancestors have been found, our genus has become more and more inclusive, incorporating more members that look less like us, Homo sapiens. By getting to know these other hominins--the ones who came before us--we can start to answer some big questions about what it essentially means to be human.

Electricity is all around us, all the time. It makes our lives easier, safer, more fun and most of us never think about it. But is there such a thing as too much electricity? Electronic devices emit an electromagnetic field, which is suspected to cause cancer. We read countless sources on this topic to summarize the results of the latest research for you.
