Molecular Vibration
A molecular vibration is a periodic motion of the atoms of a molecule relative to each other, such that the center of mass of the molecule remains unchanged. The typical vibrational frequencies range from less than 1013 Hz to approximately 1014 Hz, corresponding to wavenumbers of approximately 300 to 3000 cm−1 and wavelengths of approximately 30 to 3 µm. For a diatomic molecule A−B, the vibrational frequency in s−1 is given by \nu = \frac \sqrt , where k is the force constant in dyne/cm or erg/cm2 and μ is the reduced mass given by \frac = \frac+\frac. The vibrational wavenumber in cm−1 is \tilde \;= \frac \sqrt, where c is the speed of light in cm/s. Vibrations of polyatomic molecules are described in terms of normal modes, which are independent of each other, but each normal mode involves simultaneous vibrations of different parts of the molecule. In general, a non-linear molecule with ''N'' atoms has 3''N'' – 6 normal modes of vibration, but a ''linear'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemistry Organizations
Chemistry is the scientific study of the properties and behavior of matter. It is a natural science that covers the elements that make up matter to the compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances. Chemistry also addresses the nature of chemical bonds in chemical compounds. In the scope of its subject, chemistry occupies an intermediate position between physics and biology. It is sometimes called the central science because it provides a foundation for understanding both basic and applied scientific disciplines at a fundamental level. For example, chemistry explains aspects of plant growth (botany), the formation of igneous rocks (geology), how atmospheric ozone is formed and how environmental pollutants are degraded (ecology), the properties of the soil on the moon (cosmochemistry), how medications work ( pharmacology), and how to collect DNA evidenc ...

Research Institutes In California
Research is " creative and systematic work undertaken to increase the stock of knowledge". It involves the collection, organization and analysis of evidence to increase understanding of a topic, characterized by a particular attentiveness to controlling sources of bias and error. These activities are characterized by accounting and controlling for biases. A research project may be an expansion on past work in the field. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of basic research (as opposed to applied research) are documentation, discovery, interpretation, and the research and development (R&D) of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemologies, which vary considerably both within and between humanities and sciences. There are several forms of research: scientific, humanities, artistic, econom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Historically Black Colleges And Universities
Historically black colleges and universities (HBCUs) are institutions of higher education in the United States that were established before the Civil Rights Act of 1964 with the intention of primarily serving the African-American community. Most of these institutions were founded in the years after the American Civil War and are concentrated in the Southern United States. During the period of segregation prior to the Civil Rights Act, the majority of American institutions of higher education served predominantly white students, and disqualified or limited black American enrollment. For a century after the end of slavery in the United States in 1865, most colleges and universities in the Southern United States prohibited all African Americans from attending, while institutions in other parts of the country regularly employed quotas to limit admissions of Black people. HBCUs were established to provide more opportunities to African Americans and are largely responsible for esta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Albany State University
Albany State University is a public historically black university in Albany, Georgia. In 2017, Darton State College and Albany State University consolidated to become one university under the University System of Georgia (USG). Albany State University has two campuses in Albany (East and West Campus) and a satellite campus in Cordele (Cordele Center). History Establishment and growth Joseph Winthrop Holley, born in 1874 to former slaves in Winnsboro, South Carolina, founded the institution in 1903 as the Albany Bible and Manual Training Institute. Two educators, Reverend Samuel Lane Loomis and his wife, sent Holley to Brainerd Institute and then Revere Lay College (Massachusetts). When attending Revere Lay, Holley got to know one of the school's trustees, New England businessman Rowland Hazard. After taking a liking to Holley, Hazard arranged for him to continue his education at Phillips Academy in Andover, Massachusetts. Holley aspired to become a minister and prepared ...

Lesson Plan
A lesson plan is a teacher's detailed description of the course of instruction or "learning trajectory" for a lesson. A daily lesson plan is developed by a teacher to guide class learning. Details will vary depending on the preference of the teacher, subject being covered, and the needs of the students. There may be requirements mandated by the school system regarding the plan. A lesson plan is the teacher's guide for running a particular lesson, and it includes the goal (what the students are supposed to learn), how the goal will be reached (the method, procedure) and a way of measuring how well the goal was reached (test, worksheet, homework etc.). Main classes of symbiotic relationships While there are many formats for a lesson plan, most lesson plans contain some or all of these elements, typically in this order: * ''Title'' of the lesson * ''Time'' required to complete the lesson * List of required ''materials'' * List of ''objectives'', which may be ''behavioral objectives ...

Next Generation Science Standards
The Next Generation Science Standards is a multi-state effort in the United States to create new education standards that are "rich in content and practice, arranged in a coherent manner across disciplines and grades to provide all students an internationally benchmarked science education." The standards were developed by a consortium of 26 states and by the National Science Teachers Association, the American Association for the Advancement of Science, the National Research Council, anAchieve a nonprofit organization that was also involved in developing math and English standards. The public was also invited to review the standards, and organizations such as the California Science Teachers Association encouraged this feedback. The final draft of the standards was released in April 2013. Goal The purposes of the standards include combatting ignorance of science, creating common standards for teaching in the U.S., and developing greater interest in science among students so that more ...

Video Game
Video games, also known as computer games, are electronic games that involves interaction with a user interface or input device such as a joystick, controller, keyboard, or motion sensing device to generate visual feedback. This feedback mostly commonly is shown on a video display device, such as a TV set, monitor, touchscreen, or virtual reality headset. Some computer games do not always depend on a graphics display, for example text adventure games and computer chess can be played through teletype printers. Video games are often augmented with audio feedback delivered through speakers or headphones, and sometimes with other types of feedback, including haptic technology. Video games are defined based on their platform, which include arcade video games, console games, and personal computer (PC) games. More recently, the industry has expanded onto mobile gaming through smartphones and tablet computers, virtual and augmented reality systems, and remote c ...
