Educational Video: Shear and Torsion

I found series of videos on youtube.com illustrating the concept of shear and torsion affecting the structures during the earthquake. The instructors are from U of Illinois and supported by NSF and NEES (www.nees.org). In the video, the instructors deliver the complex concepts of shear and torsion in very simple way so that the audiences can understand the concepts very easily. Let's watch the videos below:

Machu Picchu

Machu Picchu

It is one of the Seven Wonders of the World. This is mystical place and a great spot to divinity. It is the Peru’s most popular place, so most of you like to see the place. People of Machu Picchu feel that they are the creators of god. This place offers you strange forces of nature that permit the individual to attain a contrary cosmic state.

The place is located at 2300 meters above the sea level. So, you can enjoy the vicinity of the place. One day is enough to visit the spots around Machu Picchu.

While planning to visit Machu Picchu, you need to understand a little about the geography of this area, because the location is remote and inaccessible.
