Evolution Technology Vs Evolution Until the recent discovery of cloning, no one thought that technology was in any way related to morality. In reality isn’t technology against the morals of the natural world to begin with? But is there even such a thing as a purely selfless act? Sure there are actions that seem selfless, but the reason for doing them is consciously or unconsciously selfish. Evolution is a natural occurrence that one would think is unselfish and completely moral, however in reality the process of evolution is very selfish. It is a species genes changing so that the species will ultimately survive, this is an act that only helps that species. Technology is created to conform to how far evolution has gone. Technology is the next step in the evolution process for humans, and it is making all humans a little more immoral. A tribal shaman â€Å"ensures that the relation between human society and the larger society of beings is balanced and reciprocal, and that the village never takes more form the living land than it returns to it – not just materially but with prayers, propitiations, and praise† (Abram 5). While this seems to be natural and morally thanking the earth for what is has given, the shaman are doing this because the â€Å"scale of a harvest or the size of a hunt are always negotiated between the tribal community and the natural world† (Abram 5). This seemingly selfless act is really only to help the amount of food they can grow or catch that season. This leads to the thought that there is no such thing as a purely moral person. â€Å"If people think they are at times unselfish, so the argument goes, they must be hiding the selfish motives from themselves. In other words, all of us have two agendas: one hidden in the recesses of our minds, and one that we sell to ourse lves and others† (De Waal 662). What this is saying is that even if someone has no thought in their head that what they are about to do is unselfish; the...

Learn Chemistry - A Guide to Basic Concepts

Learn Chemistry - A Guide to Basic Concepts Chemistry is a logical science. You can master the essential concepts yourself. You can study these concepts in any order, but its probably best to start from the top and work your way down  since many concepts build on understanding units, conversion, and how atoms and molecules interact. Key Takeaways: How to Learn Chemistry Its possible to learn the basic concepts of chemistry online.Chemistry concepts should be studied in a logical order because concepts build upon each other. Jumping into the middle of the science can lead to confusion.While its fine to learn chemistry principles online, be aware that the lab component is an important part of the science. Its a good idea to supplement textbook learning with experiments using a chemistry kit. Introduction to Chemistry: Learn about what chemistry is, what chemists do, and why you would want to study this science.Units Measurements: Get a handle on the metric system and the common units used in chemistry.The Scientific Method: Scientists, including chemists, are systematic about the way they study the world. Find out how to use the scientific method to collect data and design experiments.The Elements: Elements are basic building blocks of matter. Learn what an element is and get facts for them.The Periodic Table: The periodic table is a way elements can be organized, based on their similar properties. Find out what that table is, how it was designed, and how you can use it to make your study of chemistry much easier.Atoms and Ions: Atoms are single units of an element. Ions can be made up of one or more types of elements and carry an electrical charge. Learn about the parts of an atom and how to identify the different types of ions.Molecules, Compounds, Moles: Atoms can b e joined together to make molecules and compounds. A mole is a useful way of measuring an amount of atoms or larger components of matter. Define these terms and learn how to perform calculations to express quantities. Chemical Formulas: Atoms and ions dont bond together randomly. Find out how to predict how many of one type of atom or ion will combine with others. Learn to name compounds.Chemical Reactions Equations: Just as atoms and ions combine in very specific ways, molecules and compounds react with each other in definite quantities. Learn how to tell whether or not a reaction can occur and what the products of a reaction will be. Write balanced chemical equations to describe reactions.Thermochemistry: Chemistry is the study of both matter and energy. Once you learn to balance the atoms and charge in a chemical reaction, you can examine the energy of the reaction as well.Electronic Structure: Electrons are found in regions around the nucleus of an atom. Learning about the structure of the electron shell or electron cloud is important for understanding how atoms and ions will form bonds.Chemical Bonds: The atoms in a molecule or compound are attracted and repelled with respect to each other i n ways that determine the types of bonds they can form. Molecular Structure: Once you understand the types of bonds that can be formed between components in a substance, you can begin to predict and understand how molecules are formed and the shapes they take. Valence shell electron pair repulsion (VSEPR) theory helps chemists understand molecular structure.Liquids Gases: Liquids and gases are phases of matter with properties distinctly different from the solid form. Collectively, liquids and gases are termed fluids. The study of fluids and how they interact is important for understanding the properties of matter and predicting the ways in which that matter can react.Rates of Reaction: Several factors affect how quickly and completely a reaction proceeds. Learn about these factors and how to calculate the speed at which a reaction can occur.Acids Bases: There are several ways to define acids and bases. One way is to look at hydrogen ion concentration. No matter which method you choose, these categories of chemicals participate in some v ery important reactions. Learn about acids, bases, and pH. Oxidation Reduction: Oxidation and reduction reactions go hand in hand, which is why they are also called redox reactions. Acids and bases may be thought of as reactions involving hydrogen or protons, while redox reactions tend to be concerned with electron gain and loss.Nuclear Reactions: Most chemical reactions involve exchanges of electrons or atoms. Nuclear reactions are concerned with what happens inside the nucleus of an atom. This includes radioactive decay, fission, and fusion.
