MENTE NUEVA DEL EMPERADOR, LA /CYTComo dice Martin Gardner en el prlogo a esta obra, "los grandes matemticos y fsicos encuentran sobremanera difcil o poco menos que imposible escribir un libro que los profanos podamos entender". Sin embargo, Roger Penrose, uno de los ms notables fsico matemticos de la actualidad, ha emprendido la tarea de producir un libro destinado al pblico culto en general, en donde expone principios de la teora de la relatividad, de la mecnica cuntica y otros.

Only about 1.75 inches thick, and hard as a rock.
Size: 2.7"H (Standard)
This is nowhere near the 2.7 inches advertised. After waiting 4 days for it to expand, it never got higher than 1.75 inches from bottom to the highest point. Also, I'm not sure what kind of Talalay they claim to use; this was hard as a rock.

Great Pillow!
Size: King (Pack of 1)
Excellent product. I have been searching for a pillow that wasn't too soft or too hard and supported my neck. I now wake up without a stiff neck and a headache. Wonderful!
