Chapter 1 Even though Africa had a massive time advantage America had a much greater environmental diversity‚ so the Native American’s would have a advantage over thee Africans. Because of all the islands around Australia and New Guinea the colonist would travel to a new island and would adapt and populate the island. Because of this it brought an unprecedented golden age of successful human population explosions. Because of the population explosions‚ Australia would have had a massive head start

products style and ethos. Wool Felt and Felted Synthetic Materials Felt in its many forms can be your best solution for product design challenges. Wool felt is one of the world’s oldest man-made fabrics because it does not require weaving. Instead‚ it interlocks to form a continuous useful material. Through a process of manipulating‚ hammering‚ and steaming‚ scales on the wool felt fibers engage each other to form a lasting‚ resilient bond. The natural fibers in wool felt cannot be duplicated in

A simple coffee-cup calorimeter can be constructed using two Styrofoam cups nested inside each other. The Styrofoam prevents heat loss to the surroundings‚ which makes it an ideal calorimeter.

Police patrol strategies are based upon two unproven but widely accepted hypothesis. One of the being that by seeing police around the streets it reduces the crime that is being occurred in the streets‚ and the other one is that people fear less about crimes occurring when there is police present. These strategies were made to reduce the crimes and make the public feel more safe in the street. The Kansas City Experiment started on October 1972 and continued to 1973 ‚ it was administered by the Kansas
