New Science essays The New Science: Prosperity or Plague? As humanity approaches the new millennium, we are forced to make decisions regarding the future of our race. Our past history has shown us how far we have come and how much we have relied on technology. Will we continue to depend on the new science even with the emergence of controversial issues such We as a race must ultimately decide whether the new science is a prosperity or a plague. It is my firm belief that the increased use of science and technology will set us on road of demise that might ultimately destroy With just one command, a terrorist can detroy an entire countrys population. Just one angry terrorist can set off a World War 3. Just one. This scary thought is the culmination of our increased use of science on weapons. The craetors of biological weapons might regret their actions now, but those actions cant be changed. At that time, these craeyors believed they were creating biological weapons for the good of science, and they truly believed that this would help the world. Because of sciences lack of a limit we are forced into this tight situation in which there is no turning back. Another issue that proves how the new science will be a plague for us is cloning. At the beginning of the realization that we could create identical beings, many people were hopeful for the idea and advocated it be tested on humans. Som even proposed the idea of using clones asdonors for body organs and body parts. Many still feel the same way now. Who are we to play around with the ability to create life? That ability was meant for God and the universe to hold, not for us to play around with. And using clones for body parts? Who are we, to decide who dies? Besides the moral issues, other issues come into play when discussing cloning. One ...

List 10 Types of Solids, Liquids, and Gases

List 10 Types of Solids, Liquids, and Gases Naming examples of solids, liquids, and gases is a common homework assignment because it makes you think about phase changes and the states of matter. Examples of Solids Solids are a form of matter that has a definite shape and volume.

Liquids can flow and assume the shape of their container.

Gases expand to fill the space they are given.

Gases become liquids; liquids become solids. On the other hand, increasing temperature and decreasing pressure allows particles to move further apart. Solids become liquids; liquids become gases. Depending on the conditions, a substance may skip a phase, so a solid may become a gas or a gas may become a solid without experiencing the liquid phase.
