2019-01-10T11:19:23-08:00 October 18th, 2004|Aerospace Engineering, Issue V, Physics, Volume V|

Electric or ion propulsion is the newest propulsion system that NASA has put into successful operation. The Deep Space 1 mission used the ion engine as its primary propulsion system and tested its capabilities for the 21st century. Its advantages over conventional propulsion include lower fuel weight, much higher fuel efficiency, and longer operational life. [...]

Curves of Steel: CATIA and the Walt Disney Concert Hall

2019-01-10T10:47:29-08:00 January 1st, 2004|Building & Architecture, Computer Science, Issue V, Volume V|

The Walt Disney Concert Hall, designed by architect Frank Gehry, makes extensive use of computer technology. Without the use of CATIA (Computer-Aided Three-Dimensional Interactive Application), construction of the concert hall would have been impossible. After a physical model is built, the model is scanned by a laser device that transmits coordinates to the CATIA program. [...]

The Changing Face of Paintball
