The Advent of the Computer Mouse

The computer mouse became a mainstream accessory for computers shortly after Steve Jobs viewed a prototype mouse from Xerox in 1979. Jobs asked his team to create a mouse which was under $15.00, would last for 2 years, and could be used upon either a particle board desk or the jeans of a persons lap. Dean Hovey ended up creating the concept of the computer mouse by visiting a drug store after Jobs made this request in a business meeting. Hovey purchased a roll on deodorant and a butter dish and began working upon the initial design. Hovey popped the spherical applicator out of the deodorant and covered it with the butter dish to make a rollable, undulating handheld device

The Evolution of the Eye

The eye has developed within the animal kingdom for one reason only; to detect the world around the observer. The first evolved eyes were simply an apparatus which had a light sensitive cell referred to as “rhodopsin”. Eventually as time progressed, eyes developed a spherical shape which allowed more light to be captured so that the difference between light and dark was more distinct. Following this, eyes evolved the ability to develop a pupil which acts as a biological aperture which can constrict and dilate letting either more or less light into the eye. This system works in theory but the real world application developed a problem in that when constricting the pupil to focus on an object being looked at, less light is let in which restricts vision. Nature eventually alleviated this issue by placing a lens behind the aperture of the pupil which allowed for precision detail, clarity, and focus. This system was so effective that evolution produced some form of it for nearly every animal and insect on Earth, some being more adept than others, but all using the same principal of light and focus to observe information around them
