Electric fish were again reported millennia later by ancient Greek, Roman and Arabic naturalists and physicians. Several ancient writers, such as Pliny the Elder and Scribonius Largus, attested to the numbing effect of electric shocks delivered by catfish and torpedo rays, and knew that such shocks could travel along conducting objects. Patients suffering from ailments such as gout or headache were directed to touch electric fish in the hope that the powerful jolt might cure them. Possibly the earliest and nearest approach to the discovery of the identity of lightning, and electricity from any other source, is to be attributed to the Arabs, who before the 15th century had the Arabic word for lightning (raad) applied to the electric ray. Ancient cultures around the Mediterranean knew that certain objects, such as rods of amber, could be rubbed with cats fur to attract light objects like feathers. Thales of Miletos made a series of observations on static electricity around 600 BC, from which he believed that friction rendered amber magnetic, in contrast to minerals such as magnetite, which needed no rubbing. Thales was incorrect in believing the attraction was due to a magnetic effect, but later science would prove a link between magnetism and electricity.

The problem of the modern world is that we have created far too much hazardous chemical since it does the daily chores, like that of scrubbing the floor, in a faster and easier pace, unknowing that this can harm the ozone layer.

As we all know chicken is one of the most common foods that we eat, and that is our reason of pursuing this project. We would like to help the poultry-raisers to raise chickens in a small period of time. If we succeeded with this project we can also help our economy to grow and make it more influential. This project is also against on non-organic raisers because we are not sure about the side effects of that chemical once we intake the chicken.
