This health course will show you why exercise is a fundamental component of a healthy lifestyle.

Exercise is more than just an “art of converting big meals and fattening snacks into back strains and pulled muscles by lifting heavy things that don’t need to be moved, or running when no one is chasing you.” (Anonymous quote) Our bodies evolved to move over several millennia.

Did you know that physically active obese individuals live longer than inactive thin individuals? Are you interested in seeing the evidence on the benefits and risks of stretching? What is the best way to treat your ankle, knee, and/or shoulder injury? How does injury affect mood and what are the consequences?

Whether you are a competitive athlete, an aspiring musician or dancer, whether you play for fun or just want to lead an active lifestyle, this course will entertain and challenge you. You will learn the basic and advanced principles of body movement and biological, psychological and social issues related to activity, sport, injury and rehabilitation. The course will include content from leading global experts in multiple fields related to the science of exercise.

Do you love printed paper and wonder how much longer it will survive in the age of ebooks? Are you curious about how the mass-produced modern book emerged in the first place?  Come behind the scenes in Harvard’s libraries to explore the look, feel and even smell of nineteenth-century British and American books in this module of The Book: Histories Across Time and Space.

In 19th-century Britain and America, schooling expanded, paper cheapened, and new technologies allowed print to reach wider audiences than ever before.  After the rare and beautiful manuscripts and books showcased by earlier modules, the mass-produced, disposable objects that survive from the nineteenth century bear witness to the rise of the reading public.

This module investigates what scholars know about nineteenth-century reading, as well as how they know it.

This module’s six sections guide you through underlined, inscribed, defaced and repaired books in Harvard’s collections:

1. Name That Book
Find out what you can tell about a book when you’re blindfolded.

2. Handheld Books and Mobile Readers
What book did one soldier carry to Civil War battlefields in his pocket? (Hint: it’s not what you think.)

3. The Pen and the Needle
Did 19^th-century girls have to choose between sewing and reading?  The holes pricked in one book suggest they did both at once.

4. Leaving your Mark
Luckily for future historians, these children didn’t listen when people told them not to write in their books.

5. Detective Work
Try out some tools that build on what you’ve learned about books at Harvard to discover the stories hidden in your local library.

6. Over to You
Your chance to share what you have found in the books around you.

Join us, and discover how people in the first information age read, underlined, and repaired the pages that they treasured.

When we think of liturgy today, we imagine short, formal, congregational events happening periodically within the confines of churches. Medieval liturgy, however, took up many hours of every day, filled the city's largest meeting halls, and even spilled onto the streets. At the center of the medieval liturgy were the books we will study in this course.

In this module of The Book: Histories Across Time and Space, we’ll explore and explain the beautiful service books of the medieval church. No prior knowledge of liturgy or Latin is required, but there will be a lot of both, along with music.

The medieval services consisted of a complex system of cycles, and the liturgical books correspond to the various functions of the people who used them: Laypersons, nuns and monks, readers, singers, priests, and bishops.

We will explore and examine these precious objects using materials from Harvard’s collections. Close examination of various types of books will help to explain the complex and collaborative nature of medieval worship. Ultimately, we will learn how these beautifully adorned books  represent the importance of liturgy as an essential function of society in the Middle Ages.

As books “go digital,” we can appreciate what is gained in terms of convenience, accessibility and interconnectedness. However, we should also consider what is lost as texts transition to a digital sphere.

This module of The Book: Histories Across Time and Space seeks to re-introduce learners to the codex – a handwritten and hand-constructed book - as a three-dimensional object whose characteristics produce meaning in the experience of the reader.

This module is designed to walk you through the process of making a medieval manuscript. Using a wide variety of examples from the collections of Harvard’s Houghton Library, it will familiarize you with basic terms and concepts and give you a “feel” for the shapes, sizes, formats, materials and considerations of craft that went into the making of the book as we know it.

Throughout the Middle Ages there existed an intimate relationship between making and meaning. Codices were tactile as well as visual objects designed to engage multiple senses. In the illuminated manuscript, it is often impossible to distinguish neatly between text and image; rather, letters assume imagistic forms and images take the form of letters.

Bookmakers were sensitive to the interplay of materials, from the parchment of the pages to the wooden boards, designed to protect the contents. Each of these elements conditioned a reader’s interaction with the book. Bookmaking required a significant material investment. The production process was laborious and lengthy, involving many separate stages and craftsmen.

Books participated in a wide range of ritual, liturgical, devotional, educational and practical contexts, each of which in turn conditioned the presentation and reception of both their form and content.

Medieval Europe has preserved enormous quantities of books and documents—many millions of pages, in fact—written in Latin and other languages. However, only a tiny percentage of these texts have been edited and published. To gain access to the rest, you need to learn the art and science of reading medieval handwriting,

This module of The Book: Histories Across Time and Space introduces students to the world of medieval paleography, the science of reading old handwriting. This particular module focuses on notarial handwriting from the city of Marseille in the 14th and 15th centuries. The module features household inventories, which identify some of the fascinating objects found in people’s houses. Assessments and quizzes will allow you to track your progress as you move from letter-group to letter-group. In addition to learning the handwriting, we will take special care to explore some of the many abbreviations and other elements of the secular registers of the later Middle Ages.

Some knowledge of Latin or another Romance Language will be very helpful for understanding the texts you will read, but students without these language skills will still enjoy this chance to explore medieval handiwork.

Thousands upon thousands of manuscripts written in Latin and other languages remain from the 12th century, when Western Europe saw an unprecedented increase in manuscript production. Of these manuscripts from the middle ages, only a small percentage have been identified, much less edited and published. To explore these fascinating texts, you need to learn the art and science of reading medieval handwriting.

This module of The Book: Histories Across Space and Time introduces students to medieval paleography, the science of reading old handwriting, with a focus on the era of the 12th century. By studying a representative hand in depth, you will learn to read 12th century Transitional Gothic script and decipher the abbreviations that set the pattern of writing for the following centuries before print. We will work with selected manuscripts from Harvard’s Houghton library and enter into the cultural world of the 12th century monasteries and schools. Assessments and quizzes will allow you to track your progress as you move through letter forms and abbreviations to read whole blocks of text.

Some knowledge of Latin will be very helpful for understanding the texts you will read, but students without the necessary language skills will still enjoy this chance to explore 12th century hands.

Printing, or the capacity to reproduce text and image mechanically, has rightly been hailed as a technology with far-reaching impact. But the technology takes more than one form and originated in more than one historical context.

In this module of The Book: Histories Across Space and Time, you will learn how early printed books in mid-fifteenth century Europe were first modeled on medieval manuscripts, but soon developed new conventions that remain familiar to us today. This module also explores printing in East Asia, by wood block and movable type, and the late dominance of manuscript production in the Islamic world. 

In the first units of this module we compare and contrast manuscripts and printed books produced mainly in Europe from 1470-1700, looking at continuities and differences in layout, format, and the methods, materials, and economics of production. We also discuss examples of illustrated books and of handwritten annotations in books, including marginal annotations by readers and the marks of censors.

Two shorter units in this module focus on printing in East Asia, especially China, to highlight the features of woodblock printing which was common there, and on the Middle East, especially the Ottoman context, where a vibrant manuscript culture remained dominant until 1800. Taken together, this module gives an overview of three different contexts and technologies of book production before 1800.

Each unit features rare manuscripts and printed books in the Harvard Libraries, which viewers can investigate in more depth within the courseware and on their own.

This course is an introduction to the making and use of scrolls in the European Middle Ages. The codex, with its portability and instant access to any place in the text, became the dominant container for writing after the 4th century BCE, but scrolls continued to be made. Why and how did the scroll format remain popular and relevant in the age of the codex? This course proposes four main reasons, which 

account for essentially every kind of scroll that still exists today. We will see and examine in detail a number of beautiful objects, and come to understand the thinking of those who chose the scroll format for their texts.

This module features four main units, each of which is based on one of the reasons for scroll-making:

1. Scrolls of indeterminate length
2. Scrolls in long format
3. Ceremonial and archaizing scrolls
4. Portable scrolls

Scrolls in the Age of the Book also features a guided tour of an exhibition on Harvard University’s collection of medieval scrolls, held at Houghton Library, Harvard’s special collections library, in Spring 2014. Each scroll featured in the exhibit has been fully digitized by Harvard’s Preservation Services division, and participants will have the opportunity to interact with them in unprecedented fashion using Mirador, a state-of-the-art web application developed by Harvard and Stanford Universities.

This is a module in the series The Book: Histories Across Time and Space.

This module of The Book: Histories Across Time and Space focuses on the physical qualities of books, the role of books in 17th and 18th century France, and the emergence of literature as a modern form of culture.

We will focus on the importance of books as physical objects and the raw material of literature--namely, paper.  By considering the nature of paper and how it was made during the early modern period--from Gutenberg's time to the early nineteenth century--we can begin to understand the character of books and the way they worked.

This module also examines how books fit into the legal and political system of France under the Old Regime during the seventeenth and eighteenth centuries, when the French set standards imitated throughout Europe.  Before modern copyright, legal books had privileges, granted by the king, which provided a guarantee of quality as well as certification of   orthodoxy.  To qualify for a privilege, books had to be approved by censors.  Uncensored books, including most of the works of the Enlightenment, were usually produced outside France and circulated in the kingdom through a vast underground distribution system. 

In addition, this module addresses the emergence of literature as a modern form of culture, which can be studied best in eighteenth-century England.  The first copyright law (1710), a high rate of literacy, a booming consumer market, a precocious periodical industry, and entrepreneurial publishing concentrated in London led to the development of a new kind of author--the independent writer. Samuel Johnson epitomized this new phenomenon. This module will allow you to get a close look at him and everything he represented by providing access to the Hyde Collection of Johnson's books and papers in Houghton Library at Harvard.

In Medieval Europe the Book of Hours, so called because its core component consists of the Hours of the Virgin, became the prayer book of choice for worshippers prosperous enough to commission or purchase such a book.

Although its contents were of monastic origin, literate lay readers were the most likely to use books of hours, as served not only as a prayer book, but also as a way of keeping track of the calendar, often doubling as a family chronicle.

Books of hours provide insight into broad patterns of piety marking the High and later Middle Ages, and through their choice of texts, images and added materials, inform us about the interior life and aspirations of everyone from kings and queens and lords and ladies to monks and nuns and, ordinary members of the patrician class, merchants and others.

In this course, we will explore how books of hours provide the closest thing we have to a comprehensive and continuous record of the development of painting across most of western Europe from the later thirteenth through the early sixteenth century.

“The Book of Hours” is one module of a series of courses called “The Book: Histories Across Time and Space.” You may take this course on its own, or with the other courses of the series.

Mining underpins much of our technology and industries as well as modern society in general. A successful mine should be run efficiently and responsibly from exploration through to closure, with sound economic management every step of the way. In this course you’ll examine the business aspect of mining, focusing on the life cycle of a gold mine and discovering the technical and economic issues that affect the exploration, planning, operation and closure of a large-scale mining project.

The Business of Mining has recently won the Best in Class in the University category of the Interactive Media Awards in the USA. The judging criteria included design, content, feature functionality, usability, standards compliance and cross-browser compatibility.

This is a course for those who are interested in the challenge posed by massive and persistent world poverty, and are hopeful that economists might have something useful to say about this challenge. The questions we will take up include: Is extreme poverty a thing of the past? What is economic life like when living under a dollar per day? Are the poor always hungry? How do we make schools work for poor citizens? How do we deal with the disease burden? Is microfinance invaluable or overrated? Without property rights, is life destined to be "nasty, brutish and short"? Should we leave economic development to the market? Should we leave economic development to non-governmental organizations (NGOs)? Does foreign aid help or hinder? Where is the best place to intervene? And many others.

At the end of this course, you should have a good sense of the key questions asked by scholars interested in poverty today, and hopefully a few answers as well.

Chemistry and biology are traditionally taught as separate subjects at the high school level, where students memorize fundamental scientific principles that are universally accepted. However, at the university level and in industry, we learn that science is not as simple as we once thought. We are constantly confronted by questions about the unknown and required to use creative, integrated approaches to solve these problems. By bringing together knowledge from multidisciplinary fields, we are empowered with the ability to generate new ideas. The goal of this course is to develop skills for generating new ideas at the interface between chemistry and biology by analyzing pioneering studies.

Registration will be open throughout the course.

A House Divided: The Road to Civil War, 1850-1861 begins by examining how generations of historians have explained the crisis of the Union.  After discussing the institution of slavery and its central role in the southern and national economies, it turns to an account of the political and social history of the 1850s. It traces how the issue of the expansion of slavery came to dominate national politics, and how political leaders struggled, unsuccessfully, to resolve the growing crisis. We will examine the impact of key events such as Bleeding Kansas, the Dred Scott decision, the Lincoln-Douglas debates, and John Brown’s raid on Harper’s Ferry, and end with the dissolution of the Union in the winter of 1860-61.

This course is part of the X Series, Civil War and Reconstruction, which introduces students to the most pivotal era in American history. The Civil War transformed the nation by eliminating the threat of secession and destroying the institution of slavery. It raised questions that remain central to our understanding of ourselves as a people and a nation – the balance of power between local and national authority, the boundaries of citizenship, and the meanings of freedom and equality. This X Series will examine the causes of the war, the road to secession, the conduct of the Civil War, the coming of emancipation, and the struggle after the war to breathe meaning into the promise of freedom for four million emancipated slaves. One theme throughout the series is what might be called the politics of history – how the world in which a historian lives affects his or her view of the past, and how historical interpretations reinforce or challenge the social order of the present.

Politics of Freedom: The Civil War, 1861-1865 narrates the history of the American Civil War. While it examines individual engagements and the overall nature of the military conflict, the focus is less on the battlefield than on political, social, and economic change in the Union and the Confederacy. Central to the account are the road to emancipation, the role of black soldiers, the nature of Abraham Lincoln’s wartime leadership, internal dissent in both the North and South, the changing position of women in both societies, and the war’s long-term economic and intellectual impact. We end with a look at the beginnings of Reconstruction during the conflict.

This course is part of the XSeries, Civil War and Reconstruction, which introduces students to the most pivotal era in American history. The Civil War transformed the nation by eliminating the threat of secession and destroying the institution of slavery. It raised questions that remain central to our understanding of ourselves as a people and a nation – the balance of power between local and national authority, the boundaries of citizenship, and the meanings of freedom and equality. This XSeries will examine the causes of the war, the road to secession, the conduct of the Civil War, the coming of emancipation, and the struggle after the war to breathe meaning into the promise of freedom for four million emancipated slaves. One theme throughout the series is what might be called the politics of history – how the world in which a historian lives affects his or her view of the past, and how historical interpretations reinforce or challenge the social order of the present.

1865-1890: The Unfinished Revolution, examines the pivotal but misunderstood era of Reconstruction that followed the Civil War, the first effort in American history to construct an interracial democracy. Beginning with a discussion of the dramatic change in historians’ interpretations of the period in the last two generations, the course goes on to discuss how Reconstruction turned on issues of continued relevance today. Among these are: who is an American citizen and what are citizens’ rights; what is the relationship between political and economic freedom; which has the primary responsibility for protecting Americans’ rights – the federal or state governments; and how should public authorities respond to episodes of terrorism? The course explores the rewriting of the laws and Constitution to incorporate the principle of equality regardless of race; the accomplishments and failings of Reconstruction governments in the South; the reasons for violent opposition in the South and for the northern retreat from Reconstruction; and the consolidation at the end of the nineteenth century of a new system of white supremacy.

In ordinary life we barely notice the operations of our own minds. In The Conscious Mind - A Philosophical Road Trip, we will illuminate what we take for granted in perception, action, and interaction with others. We’ll explore this mindful awareness through demonstrations, illusions, brainteasers, thought experiments, riddles and jokes, all designed to shake you loose from your ordinary assumptions about the way consciousness works. 

You will explore your own mind and the minds of others in a new way, using a philosophical approach known as phenomenology. You’ll encounter some of the main ideas of the phenomenological tradition, through short readings by Edmund Husserl, Martin Heidegger, Jean-Paul Sartre, Simone de Beauvoir, and Maurice Merleau-Ponty. Their ideas are provocative and will animate the online and offline conversation as we proceed. But the main approach of the course will be experiential and experimental. You’ll learn phenomenology by doing it and journeying among the structures and elements of your own conscious experience.  

Students will question for themselves the meaning of human freedom, responsibility and identity by reading and responding to Dante Alighieri's Divine Comedy. The Comedy, which is richly steeped in the medieval culture of the 14th century, still speaks vividly to modern readers struggling with the question, “who am I?” Dante, as a Florentine, a poet, a lover, and religious believer, struggled with the same question in each facet of his life before coming to a moment of vision that wholly transformed him as a person.

As a 21st century reader, you will encounter the poem in a novel online environment that integrates knowledge from the disciplines of literature, history, psychology, philosophy, and theology with modern technology. You will be guided through the poem by means of the "MyDante" Project, an online environment developed by Professor Ambrosio in collaboration with the Georgetown University Center for New Designs in Learning and Scholarship (CNDLS), which will aid your own contemplative engagement with the poem. Alone and with the edX community, you will reflect on both Dante's interpretation of freedom and how it functions in the formation of personal identity, and the problem of finding appropriate metaphors to discuss these issues in our modern life.

You, the modern reader, will only understand the full implications of Dante's poetry if you participate with it in a way that is personal and is genuinely contemplative. You will discover that contemplative reading goes beyond the literal meaning, and even beyond the traditional allegorical and interpreted meaning, to apply every possible meaning contained in the text to your own life and identity. Through the MyDante platform, you will learn to know yourself in your own historical, personal, and spiritual contexts as you journey towards your understanding of your personal freedom and identity.
