The Most Basic Unit of Matter The Atom

The basic unit of all matter is the atom. The atom is the smallest unit of matter that cant be divided using any chemical means and the building block that has unique properties. In other words, an atom of each element is different from an atom of any other element. However, even the atom can be broken into smaller pieces, called quarks. Structure of the Atom An atom is the smallest unit of an element. There are 3 parts of an atom: proton: positive electrical charge, found in the nucleus of an atomneutron: neutral or no electrical charge, found in the nucleus of an atomelectron: negative electrical charge, found circling the nucleus The size of the proton and neutron are similar, while the size (mass) of the electron is much, much smaller. The electrical charge of the proton and electron are exactly equal to each other, just opposite to each other. The proton and electron attract each other. Neither the proton nor the electron is attracted or repelled by the neutron. Atoms Consist of Subatomic Particles Each proton and neutron consist of even smaller particles called quarks. The quarks are held together by particles called gluons. An electron is a different type of particle, called a lepton. proton: consists of 2 up quarks and 1 down quarkneutron: consists of 2 down quarks and 1 up quarkelectron: is a lepton There are other subatomic particles, too. So, at the subatomic level, its difficult to identify a single particle that could be called the basic building block of matter. You could say quarks and leptons are the basic building blocks of the matter if you like.

Rhetorical Analysis of Cultural Baggage Essay - 599 Words

Jenny Stout Professor Bowers English 1102 5 September 2014 Rhetorical Analysis In Barbara Ehrenreich’s Cultural baggage, the topic of ethnic heritage is discussed as the author is responding to an acquaintance asking her what her ethnic background is. Ehrenreich finds her purpose for writing her essay in making readers aware that no ethnic background is in fact a background. She takes on a not so common viewpoint of herself as most people pride themselves in where they came from and the traditions of their culture, rather than feeling almost embarrassed to claim their background. Ehrenreich claims that she has no ethnic background, disregarding her Scottish, English, and Irish heritage. While others â€Å"stand up and proudly reclaim†¦show more content†¦Ehrenreich was finally able to feel a sense of pride knowing that â€Å"the race of ‘none’ marches on.† The author wrote her essay including several references to certain traditions that different cultures practice. The audience is assumed to have some g eneral knowledge of different cultures, but nothing to extensive. The author also assumes that the audience is somewhat well educated due to the higher-level word choices she makes. Ehrenreich is describing her realization of heritage to her audience in the possible hopes that the readers can either relate in some way or share some of the excitement that she does in her own ethnicity, or lack of. Ehrenreich was able to make her point that she does in fact have an ethnicity other than Scottish, English and Irish. It was intriguing to see the progression in the essay from the authors feeling of disconnect with her heritage to a sense of pride in her family that refrains from carrying on cultural activities. She recognizes where she came from and concludes that no tradition is a tradition, rather than trying toShow MoreRelated The Relationship of Photographs, History, and Memory Essay5378 Words   |  22 Pagescontrast to earlier times--has been chronicled by a visual narrative that r elies on the attraction of photographs as means of storing and disseminating information.

A nationwide study concluded that although teachers have increased computer availability in their classrooms, they are not integrating computers into the standard curricula. The present study examined â€Å"technophobia† as an explanation for low levels of computer utilization. Elementary teachers, secondary science teachers and secondary humanities teachers in 54 schools across five urban school districts completed three measures of technophobia and a measure of demographic characteristics, computer/technology experience, computer availability, and current computer use. Results indicated that: (1) computers are available at all schools, but are not being used by many teachers; (2) many teachers are technophobic, particularly elementary teachers and secondary humanities teachers; (3) teachers are most worried about dealing with the actual computer machinery in their classroom, about computer errors, and about learning to use computers. Many people do not know how, or even when computers were first made. Even before the first electronic computers were made, many people believe that computers started with the abacus, a simple counting device. The abacus is believed to have been built in Babylon in the fourth century B. C. The First Generation of computers started in the very late 1930s. These computers were grotesquely slow, colossal in size, created much heat, used hundreds of kilowatts of power, and were about as reliable as a used up match. As time went on, these computers evolved from using vacuum tubes to transistors. Transistors mark the beginning of the Second Generation of computers in 1947.
