Movernos ¿hacia dónde?
Rubén Álvarez Mendiola / Editorial Educación Futura El gobierno de la República tendrá que explicar ahora a la sociedad entera cómo espera que nos sigamos moviendo.

Throwback Thursday: How Big is Our Observable Universe? (Synopsis)
Posted by Ethan “The mind, once expanded to the dimensions of larger ideas, never returns to its original size.” –Oliver Wendell Holmes But it isn’t just your mind that expands as time goes on and you increase your knowledge, but the entire Universe as well.

This Week In Science: Walruses Invade, Cyanide Clouds, And A Surprising Discovery On The Moon
World Science Festival Staff Seven days; lots of science in the news.

Did I ever tell you how exciting snails are?

Why big animals do not have higher cancer risks

Más allá del aula y del tiempo
Jorge Pedraza Salinas Es difícil poder establecer donde termina la influencia de un maestro. Una cosa si es posible decir.
