What imposes those limits? Students also will read about the future of passenger train travel, from flying trains to trains that use huge magnets to levitate inches or centimeters off the track. Some trains safely reach speeds of more than 200 mph!

Students will gain a deeper understanding of the Cold War by delving into major social studies topics in this project-based examination. The volume presents a series of broad questions touching on major themes in the social studies curriculum.

En este ensayo, Santiago Ocampos propone una mirada crítica, sin perder el estilo poético de su prosa, para un viaje literario que va desde Sófocles a García Márquez, entre otros, hacia la esencia del ser.
