Subject - Geology; Paper - Metamorphic Petrology & Thermodynamics

5

This course is a basic to advance introduction for the post graduate students in petrology. Geology is plagued by the problem of in accessibility; they see only the tiny fraction of the rocks that composes the Earth. During the processes of uplift and the erosion on the surface, but their exact place of origin is vague. As a result, a large proportion of our information about earth is indirectly coming from analysis of subsurface materials, geophysical studies, or experiments conducted at variable temperature and pressure. Metamorphic rocks are the most common rock type on Earth, and their study allows us to put constraints on the pressure, stress and temperature conditions in the crust and mantle, and on the bulk composition in these environments. Metamorphism affects rocks in three ways; it changes their mineralogy, it changes their shape, and it can change their composition.In this course we will look at the processes behind metamorphism, the description, and classification of metamorphic rocks, and how to extract information from metamorphic rocks and minerals to determine the conditions under which they formed. Metamorphism means change in form. In geology the term is used to refer to a solid-state recrystallization of earlier igneous, sedimentary, or metamorphic rocks. Such study includes description and classification of rocks as well as interpretation of their origin. Petrology is subdivided into three major rock types: Igneous, sedimentary, and metamorphic. Igneous and metamorphic petrology are combined, due to the similarity of approach and principle involved during their formation. As per the syllabus of UGC based on CBCS, I henceforth use the term metamorphic petrology and thermodynamics is to study metamorphic rocks and their processes of formation within one single paper as basic to advance for the post graduate students.This course deals with the naturally occurring rocks in field as well as laboratory analysis data that provide sufficient information how they occur in the nature. It gives idea of modern petrological theories which are widely accepted for their origin. The course emphasis the petrology which cover the Geology & its Perspective, Career in geology, Structure and classification of the silicate minerals along with Definition of metamorphism, Factors controlling metamorphism, variables / agents and types / kinds of metamorphism – contact, regional, fault zone metamorphism, impact metamorphism. Types and classification based on metamorphic agent. Regional metamorphism and paired metamorphic belts with reference to the theory of plate tectonics. Mineralogical phase rule for closed and open systems, nature of metamorphic reactions, concept and classification of metamorphic facies and facies series, Introduction to ultrahigh temperature and ultrahigh pressure metamorphism. Metamorphic zones, isograde and reaction isograde, Concept of classification of metamorphic facies, facies-series and grade, structure and textures of metamorphic rocks; chemographic projection, graphical representation of metamorphic minerals assemblages; ACF, AKF, AFM and others diagram.Description of each facies of low, medium to high pressure and very high pressure with special reference to characteristic minerals, subdivision into zones / subfacies, mineral assemblages; Metamorphic reactions and pressure – temperature conditions of metamorphism. Regional metamorphism of pelitic, calcareous, basic, and ultra basic rocks and thermal metamorphism of calcareous and pelitic rocks. Schreinemakers rule and construction of petrogenetic grids, metamorphic differentiation, anatexis and origin of migmatites in the light of experimental studies. Laws of thermodynamics; Gibb’s free energy, entropy, ∆G of metamorphic reactions (solid-solid and dehydration reactions); Geothermobarometry and PT paths. Petrographic details of some important metamorphic rocks such as - slate, phyllite, schists, gneiss, quartzite, marble, charnockite, leptynite, khnodalite etc.The course definitely provides better understanding to students for the processes and principles involved during the origin and evolution of the metamorphic rocks. The course contains video, text, assignment; quiz, case studies, references etc and I hope it will be useful for the geology students within and outside India. Last but not least, I highly accept any comments, questions, or suggestion for the improvement of this course.

Vibrations and Waves

0

A foundational study of waves and vibrations will prepare learners for advanced courses in physics and related fields of engineering. The skills utilized in analyzing these phenomena are applicable to many different systems because vibrations and waves are so ubiquitous. For instance, learners will understand how the “resonant” modes of a tall building are analogous to simple systems of coupled oscillators. Moreover, learners will come to appreciate that the concept of “resonance” applies not only to systems of masses on springs, but to sound waves, 2D surfaces, atoms, and a wide range of other systems. This course explores many properties that are universal to all wave systems as well as many particular cases.This course will prepare learners to analyze problems that involve mechanical vibrations and waves with such topics as simple harmonic motion, superposition, damping, forced vibrations and resonance, coupled oscillations, normal modes, continuous systems, reflection and refraction, and phase and group velocities. The course also explores electromagnetic waves and various associated properties like polarization, Snell’s law, Huygens’s principle, interference and diffraction. It ends by giving learners a taste of Quantum Mechanics.

Advanced Introductory Classical Mechanics

4.5

This college-level, calculus-based Introductory Newtonian Mechanics course covers all of the topics and learning objectives specified in the College Board Course Description for Advanced Placement®Physics C (Mechanics). It covers Newton’s Laws, Kinematics, Energy, Momentum, Rigid Body Rotation, and Angular Momentum. The course covers applications of these basic principles to simple harmonic motion, orbital motion, and to problems that involve more than one basic principle. These principles also underlie the 12 online laboratory activities.Our emphasis is on helping students learn expert-like ways of solving challenging problems, many of which are similar to problems on previous Advanced Placement Examinations in Mechanics C. We stress a key insight: mechanics is about forces changing motion. We apply this concept to organizing the core knowledge in a way that helps students apply it to sophisticated multi-concept problems. We feel this is the best way to prepare students for success not only on the AP Examination but also in other college-level science, technology, engineering and math courses that emphasize problem-solving.If you are a teacher looking to learn better ways to teach your students, or are interested in using some of our MOOC materials in your own classroom—possibly as a private online course for your students—we strongly encourage you to sign up for our teacher’s discussion cohort, a “private discussion room” for teachers to share pedagogical ideas and instructional techniques.To join these discussions, verify yourself as a teacher by clicking this link, and we will enroll you in the teacher’s discussion cohort.FAQHow long is this course?The course consists of 13 weeks of required (graded) material and 2 weeks of optional (ungraded) material. You do not need to complete the optional weeks in order to receive a certificate, but we strongly encourage you to complete these units, especially if you are preparing for the College Board’s AP Physics C: Mechanics exam.Is there a required textbook?You do not need to buy a textbook. A complete eText, including worked-examples and some video lectures, is included in this edX course and is viewable online. If you would like to use a textbook with the course (for example, as a reference), most calculus-level books are suitable. Introductory physics books by Young and Freedman, Halliday, Resnick, & Walker, or Knight are all appropriate (and older editions are fine).My physics is a little rusty. How should I prepare for this course?If you would like to brush-up on basic mechanics skills before taking this course, we recommend the brief warm-up course, On-Ramp to AP Physics C: Mechanics.What if I take a vacation?The course schedule is designed with this in mind! Course content is always released at least 3 weeks ahead of the deadline, providing you with the opportunity for flexibility in scheduling.How are grades assigned?There are five parts of the course that are worth points: (1) Checkpoint problems are incorporated into the reading; (2) most weeks have an interactive lab component; (3) more involved homework problems occur at the end of each week and (4) quizzes at the end of every 1-2 weeks; (5) the course culminates in a final exam. Each category is worth a varying number of points; and you are allowed several attempts on each problem. A final grade of at least 60% is needed for certification; hence you will not have to do every problem.Note: Taking this Course Involves Using Some Experimental MaterialsThe RELATE group that authors and administers this course is a physics education research group. We are dedicated to understanding and improving education, especially online. In one of the only published studies measuring learning in a massive open online course (MOOC), we showed that a previous iteration of this course produced slightly more conceptual learning than a traditionally taught on-campus course. Currently, we are working to find just what caused this learning. In this course, the RELATE group will be comparing learning from different types of online activities that will be administered to randomly assigned sub-groups of course participants. At certain points in the course, new vs. more traditional sequences of activities will be assigned to different sub-groups. We will then use common questions to compare the amount of associated learning. Which group receives the new activities will be switched so that all groups will have some new activities and some traditional ones.Our experimental protocol has been approved by the MIT Committee on Use of Human Subjects. As part of this approval we have the obligation to inform you about these experiments and to assure you that:We will not divulge any information about you that may be identified as yours personally (e.g. a discussion post showing your user name). The grade for obtaining a certificate will be adjusted downwards (from 60%) to compensate if one group has slightly harder materials.Note: By clicking on the “Enroll Now” button, you indicate that you understand that everyone who participates in this course is randomly assigned to one of the sub-groups described above.
