Con este curso aprenderás los conceptos básicos relacionados con las reacciones químicas y profundizarás en su estudio desde el punto de vista cuantitativo, es decir su estequiometría. Entenderás el comportamiento de los gases y las disoluciones y aplicarás las leyes que regulan su comportamiento en los procesos químicos en los que participan.
 
La ecuación química representa lo que sucede cuando tiene lugar un proceso en el que unas sustancias se convierten en otras mediante una “reacción química”.

En las reacciones se cumple la ley de la conservación de la masa y es posible calcular las cantidades de reactivos que reaccionan y de productos que se obtienen.
 
El estudio de las reacciones químicas y de los aspectos cuantitativos de las mismas, es decir su “estequiometría”, es competencia de la Química, una materia básica que se estudia en muchas titulaciones Universitarias.
 
Este curso va dirigido a los alumnos que acceden a la Universidad, especialmente aquellos que no han cursado Química y que requieren de los conocimientos básicos en estos aspectos.
 
Las unidades que trataremos:

• Conceptos básicos: masa, mol y fórmula química
• Gases. Ecuación de los gases ideales
• Disoluciones y formas de expresar la concentración
• Ecuaciones y reacciones químicas
• Estequiometría y cálculos en reacciones completas
• Reacciones reversibles y cálculos estequiométricos en el equilibrio

The Reading and Writing Arabic Course is intended for those who want to learn Arabic script - to read and write Arabic

Reading Fiction is designed to sharpen your skills as a critical reader. As we explore both short stories and novels focusing on the theme of "the city in literature," we will learn about the various elements that shape the way we read texts - structure, narrative voice, character development, novelistic experimentation, historical and political contexts and reader response.

This course explores the form, content, and historical context of various works of fiction specifically through the thematic lens of "dysfunctional families." We will focus primarily on questions pertaining to the structure, language, story, and characters of these fictional works.

Great works of fiction often take us to far-off places; they sometimes conduct us on journeys toward a deeper understanding of what's right next door. We'll read, discuss, and interpret a range of short and short-ish works: The reading list will be chosen from among such texts as "Gilgamesh," Homer's Odyssey (excerpts), Bunyan's The Pilgrim's Progress (excerpts), Swift's Gulliver's Travels, Mary Shelley's Frankenstein, Conrad's Heart of Darkness, Saleh's Season of Migration to the North, Woolf's To the Lighthouse, John Cheever's "The Swimmer," Coetzee's The Life and Times of Michael K, Irving's "Rip Van Winkle," Toni Morrison's Jazz, H. G. Wells' The Time Machine, Twain's The Adventures of Huckleberry Finn, Beckett's How It Is, Calvino's Invisible Cities, Forster's A Passage to India. As a CI-H class, this subject will involve substantial practice in argumentative writing and oral communication.

In this course, we will actively explore a powerful framework, Reading Apprenticeship©—described in the book, Reading for Understanding. Through video clips, readings and practice, this course provides snapshots of a proven approach to helping readers use and master a set of powerful literacy tools that will help them enjoy and understand high-quality, complex texts in and beyond school. This course is for: - Educators interested in deepening literacy with innovative, proven strategies - Teachers (K-16) supporting readers in any content area - Administrators, curriculum specialists, and teacher leaders looking for literacy professional learning that will support their schools in meeting Common Core State Standards Learn more about the Reading Apprenticeship at WestEd

"Reading Poetry" has several aims: primarily, to increase the ways you can become more engaged and curious readers of poetry; to increase your confidence as writers thinking about literary texts; and to provide you with the language for literary description. The course is not designed as a historical survey course but rather as an introductory approach to poetry from various directions – as public or private utterances; as arranged imaginative shapes; and as psychological worlds, for example. One perspective offered is that poetry offers intellectual, moral and linguistic pleasures as well as difficulties to our private lives as readers and to our public lives as writers. Expect to hear and read poems aloud and to memorize lines; the class format will be group discussion, occasional lecture.

This course will examine the origins, structure and functions of the U.S. Intelligence Community and its relationship to national security policy. It will look in some detail at the key intelligence agencies and the functions they perform, including collection, analysis, counterintelligence and covert action. It will also look at some of the key intelligence missions, such as strategic warning, counterterrorism, counterproliferation, and counterinsurgency. Finally, it will examine some of the major controversies concerning intelligence, including its successes and failures, relationship to policymakers, congressional oversight, and the need for reform.

This course examines the politics of international economic relations. We begin with a discussion of the analytical "lenses" through which we can view the global economy. We then examine the politics of trade policy, multinational corporations, and international monetary and financial relations. We will also examine third-world development, communist transition, and the debate over "globalization." Finally we will explore the fight against terrorist financing and money laundering, the proper role of international financial institutions (including the IMF), and the impact of the global economy on the ability of governments to make policy within their own borders.

This course focuses on strategic and political implications of ongoing trends in global energy markets, particularly markets for crude oil and natural gas. The course examines the world's major oil and natural gas producing regions: the Middle East, the Caspian Region, Russia, Venezuela, and the North Sea. Producer-consumer relationships are considered for China, India, Japan, and the United States. United States foreign policy implications, especially with respect to China, are discussed.

This seminar aims to develop a teaching knowledge of the field through extensive reading and discussion of major works. The reading covers a broad range of topics - political, economic, social, and cultural - and represents a variety of historical methods.

How do health professionals predict global patterns of disease? In the case of an epidemic, disaster, or armed conflict, how do experts determine what health care interventions to use? Is it possible to eradicate diseases like guinea worm and polio? How can health systems address their challenges?

In this course, learners will hear from leading experts as they engage with current issues and challenges in global health. The course will examine the global response to diseases, such as the developing Zika outbreak. The backbone of this learning experience is a set of 18 reviews, co-edited by David Hunter and Harvey Fineberg, published in The New England Journal of Medicine (NEJM). The combined reviews constitute an up-to-date survey of global health topics from authoritative leaders in the field, covering disease patterns and predictions, infectious and non-communicable diseases, and health systems and institutional responses.

Participants will read the reviews, hear from the authors through a series of interviews, and engage with the content and one another through assessments and discussion questions.

In keeping with the tradition of the last twenty-some years, the Readings in Optimization seminar will focus on an advanced topic of interest to a portion of the MIT optimization community: randomized methods for deterministic optimization. In contrast to conventional optimization algorithms whose iterates are computed and analyzed deterministically, randomized methods rely on stochastic processes and random number/vector generation as part of the algorithm and/or its analysis. In the seminar, we will study some very recent papers on this topic, many by MIT faculty, as well as some older papers from the existing literature that are only now receiving attention.

This course covers the fundamentals of mathematical analysis: convergence of sequences and series, continuity, differentiability, Riemann integral, sequences and series of functions, uniformity, and the interchange of limit operations. It shows the utility of abstract concepts and teaches an understanding and construction of proofs. MIT students may choose to take one of three versions of Real Analysis; this version offers three additional units of credit for instruction and practice in written and oral presentation.

The three options for 18.100:

• Option A (18.100A) chooses less abstract definitions and proofs, and gives applications where possible.
• Option B (18.100B) is more demanding and for students with more mathematical maturity; it places more emphasis from the beginning on point-set topology and n-space, whereas Option A is concerned primarily with analysis on the real line, saving for the last weeks work in 2-space (the plane) and its point-set topology.
• Option C (18.100C) is a 15-unit variant of Option B, with further instruction and practice in written and oral communication. This fulfills the MIT CI requirement.
