The Prospects of Invisibility Cloaks: Bending the Laws of Light

2017-11-11T17:29:05-08:00 June 27th, 2011|Electrical Engineering, Ergonomics, Issue II, Material Science, Physics, Volume XIII|

Current research and experimentation with metamaterials have led to advancements in the development of invisibility. Metamaterials can be used to make objects appear invisible by bending light around those objects through refraction instead of away from those objects by reflection. Though no natural material exhibits this behavior, engineers are working to design cloaking devices with [...]

Edible Structures: The Application of Structural Engineering in Cake Design

2017-11-11T17:13:48-08:00 December 14th, 2010|Building & Architecture, Civil Engineering, Food & Drink, Issue I, Volume XIII|

Rarely are cakes thought of as miniature buildings, but they are actually governed by the same physics that keep homes and offices upright. As such, multi-layered cakes are subject building like forces and need a support system that will hold the weight of the different layers. They share many structural elements with modern day skyscrapers [...]

Where Does My Decaf Come From?

Spread the Sound: A Brief History of Music Reproduction

2017-11-11T17:27:15-08:00 October 6th, 2010|Computer Science, Electrical Engineering, Issue II, Lifestyle, Material Science, Volume XIII|

Advancements in technology over the last 150 years have allowed people to spread music throughout the world by recording sound into a physical form and replaying it at their convenience. Music reproduction began in the late 19th century with the advent of the vinyl album, the first invention to let the masses record audio into [...]

Soaring to New Heights: The Evolution of Pole Vaulting and Pole Materials

2017-11-11T16:49:05-08:00 September 1st, 2010|Issue II, Material Science, Physics, Sports & Recreation, Volume XII|

Pole vaulting is an incredibly dynamic and complex sport that requires high levels of athleticism, precision, and skill. The process of the vault involves the transfer of energy from the vaulter to the pole, and finally back to the vaulter as he is launched into the air. As a result, the vault relies heavily on [...]
