You’re acquainted with your DNA, but did you know that your cells synthesize enough DNA during your lifetime to stretch a lightyear in length? How does the cellular machinery accomplish such a feat without making more mistakes than you can survive? Why isn’t the incidence of cancer even higher than it is? And, if the DNA in each and every cell is two meters long, how is this genetic material compacted to fit inside the cell nucleus without becoming a tangled mess?
 
Are you ready to go beyond the “what" of scientific information presented in textbooks and explore how scientists deduce the details of these molecular models?
 
Take a behind-the-scenes look at modern molecular genetics, from the classic experimental events that identified the proteins involved in DNA replication and repair to cutting-edge assays that apply the power of genome sequencing. Do you feel confident in your ability to design molecular biology experiments and interpret data from them? We've designed the problems in this course to build your experimental design and data analysis skills.
 
Let’s explore the limits of our current knowledge about the replication machinery and pathways that protect the fidelity of DNA synthesis. If you are up for the challenge, join us in 7.28.1x Molecular Biology: DNA Replication and Repair.

WHAT IS “HOW STUFF MOVES”?
Mechanics is the study of how things move. It was the first quantitative science to achieve wide power to predict behavior, including things never before directly observed. Newton, Leibniz, and others invented calculus to describe motion and we will find both differential and integral calculus extremely useful throughout this course.

This is the second in a 3-part series of courses that parallels the second-semester mechanics course taught at Harvey Mudd College. Part 2 expands on Part 1 by considering the rotation of objects, connecting new concepts of angular momentum and torque to the properties of linear motion. Part 1 examined linear motion, and Part 3 examines wave motion. This course is an invitation to develop your problem-solving skills and to learn how to apply mathematics to all sorts of problems of the physical world. Learning the rules that govern how stuff moves in the world around us is exciting; using those rules to predict correctly something that you haven’t observed means that you really understand something. It‘s a great feeling.

WHAT SHOULD I KNOW BEFORE WE START?
You need not have taken physics before, but we assume that you have studied mathematics, up to and including a first course in calculus. You may be taking a calculus course concurrently with this course; that should be a good strategy. We will introduce important calculus ideas and methods as the need arises and provide examples.

There is a Mathematics Diagnostic Test that you can take at the beginning of Part 1 of this series to ensure that your mathematics background will set you up for success in this course.

Hoy en día, más del 80 por ciento de la población en América Latina y el Caribe vive en zonas urbanas, y para el 2050 será casi el 90 por ciento. Esta creciente urbanización plantea desafíos importantes para los más de 15 mil municipios que existen en la región, exigiendo a los mismos hacer frente a las demandas de nuevos empleos, servicios urbanos, escuelas, transporte, viviendas y seguridad de forma consciente y planificada. Estas ciudades quieren avanzar hacia el desarrollo sostenible, buscando la manera de crecer económicamente, de forma inclusiva y respetando el medioambiente. ¿Pero cómo se avanza hacia el sueño de la sostenibilidad? ¿Cómo conseguimos crear actividad económica sin contaminar el aire y los ríos? ¿Cómo podemos crear riqueza y que los recursos lleguen a todas las personas? ¿Cómo hacer ciudades más seguras y participativas?

Para reflexionar sobre estas y otras preguntas, el BID ha creado un curso que busca fortalecer en los participantes las capacidades para gestionar el desarrollo sostenible de las ciudades, a través del dominio conceptual, procedimental y actitudinal de las principales áreas de competencia de la ciudad y de la herramienta de la Iniciativa de Ciudades Emergentes y Sostenibles del BID, permitiéndoles desarrollar habilidades y construir estrategias innovadoras y multisectoriales para dar respuesta a los desafíos de la sostenibilidad.

This course, the fourth installment of the multi-part Poetry in America series, explores the poetry of Emily Dickinson, one of America’s most distinctive and prolific poets. While Dickinson wrote nearly 2,000 poems during her lifetime, she chose never to publish, opting instead to revisit and revise her works throughout her lifetime.  Keeping this dynamic of self-revision in mind, we will consider a number of Dickinson’s poems—many seemingly in tension with one another—concerned with Nature, Art, the Self, and Darkness. We will travel to the Dickinson Collection at Harvard's Houghton Library, and to Amherst, Massachusetts, paying a visit to the house in which the poet lived and wrote until her death in 1886. Distinguished guests for this module include NBA athlete Jason Collins, dancers Damian Woetzel and Charles “Lil Buck” Riley, and President and CEO of the New America Foundation Anne Marie Slaughter, among others.
 
Led by Harvard Professor Elisa New, Poetry in America surveys nearly 400 years of American poetry. Through video lectures, archival images and texts, expeditions to historic sites, interpretive seminars with large and small groups, interviews with poets and scholars, and conversations about poems with distinguished Americans, Poetry in America embarks on a journey through the literature of a nation. Distinguished guests, including President Bill Clinton, Elena Kagan, Henry Louis Gates, Eve Ensler, John McCain, Andrea Mitchell, Michael Pollan, Drew Faust, Tony Kushner, and Nas, among others, bring fresh perspectives to the study of American Poetry.

What is religion? What is Hip Hop? Are they the same thing? Do they overlap? Over six weeks we’ll get a sense of how some individuals answer these questions, and you’ll get the tools you need to explore these questions for yourselves.

We will start our time together with some basic assumptions, the most important being a willingness to think about Hip Hop and religion as cultures that wrestle with the huge questions of our existence: Who are we? Why are we? Where are we?  on hip You will also need to be open to the possibility of Hip Hop as a language through which these complex and religious questions are presented, explored, and interpreted.

As this course unfolds, we’ll look closely into the relationship between Hip Hop culture and religion. We will explore the ways in which Hip Hop culture discusses and provides life meaning in complex ways through  (1) a discussion of the history and content of rap music; (2) an examination of religion in rap music; (3) an exploration of the religious sensibilities of rap artists; and (4) a discussion of the implications of the connection between rap and religion.

We will accomplish this through a unique mix of videos, readings, music, images, stories and behind-the scenes insider perspectives. 

All required readings are available within the courseware and complete texts are also available for purchase.

Join this course to enhance your understanding of the intersections between religion and Hip Hop culture in the United States. No prior knowledge is required. All lectures will be in English.

Our world is in a data deluge with ever increasing sizes of datasets. Linear algebra is a tool to manage and analyze such data.

This course is part 2 of a 2-part course, with this part extending smoothly from the first. Note, however, that part 1, is not a prerequisite for part 2. In this part of the course, we'll develop the linear algebra more fully than part 1. This class has a focus on data mining with some applications of computer graphics. We'll discuss, in further depth than part 1, sports ranking and ways to rate teams from thousands of games. We’ll apply the methods to March Madness. We'll also learn methods behind web search, utilized by such companies as Google.  We'll also learn to cluster data to find similar groups and also how to compress images to lower the amount of storage used to store them. The tools that we learn can be applied to applications of your interest.  For instance, clustering data to find similar movies can be applied to find similar songs or friends. So, come to this course ready to investigate your own ideas.
