In this engineering course, we will explore the processing and structure of cellular solids as they are created from polymers, metals, ceramics, glasses and composites. We will derive models for the mechanical properties of honeycombs and foams, and we will discover how the unique properties of these materials can be exploited in applications such as lightweight structural panels, energy absorption devices, and thermal insulation.
The Cellular Solids: Structures, Properties and Engineering Applications course provides a general understanding of cellular solids. Following this module, learners will be prepared to take one or both add-on modules to learn more about applications in medicine and to cellular materials in nature:
Taken together, these three modules provide similar content to the MIT subject 3.054: Cellular Solids: Structure, Properties, and Applications.
In this engineering course, we will explore cellular solids in medicine, including trabecular bone mechanics, the increased risk of bone fracture due to trabecular bone loss in patients with osteoporosis, the development of metal foam coatings for orthopedic implants, applying foam models to tissue engineering scaffolds and the design of a porous scaffold for tissue engineering that mimics the body's own extracellular matrix.
This course should be taken with 3.054.1x: Cellular Solids Part 1.
In this engineering course, we will explore sandwich structures and cellular solids that occur in nature, and we will consider examples of engineering design inspired by natural materials.
This course should be taken with Cellular Solids 1 for a complete survey of the structure, properties, and engineering applications of cellular solids that occur in nature.

Every day, we see concrete used all around us – to build our houses, offices, schools, bridges, and infrastructure. But few people actually understand what gives concrete its strength, resistance, and utility.
The aim of this course is to offer basic cement chemistry to practitioners, as well as new students in the fields of chemistry and engineering.
You will learn how cement is made and hydrated, as well as the environmental and economical benefits it offers. You’ll learn to test your samples in isocalorimetry in order to track the hydration and to prepare and observe samples by scanning electron microscopy. In the last two weeks of the course, you will also learn how X-ray diffraction works and how to apply it to cements.
Because the course is designed for beginning students, it’s not necessary to have a cement background, however basic concepts in chemistry and crystallography will help. This course lasts 6 weeks, during which you can take theoretical courses and tutorials to test the cement in the laboratory.
This course is set to Open-Archived mode. You may register for this course and peruse the content at your own pace, but at this time you may not pursue a certificate.
How can Iran be stopped from getting a nuclear bomb—negotiations, sanctions, or military action? As a participant in this course, you will advise the president in deciding whether, and how, the U.S. should act. Once you’ve made your assessment, you will move on to wrestle with other scenarios preoccupying policy makers. Between the Assad regime and ISIS, civilians in Syria and Iraq face unimaginable atrocities. Should the U.S. intervene? China’s rise is rattling capitalist economies and a half-century of Pacific peace. What counterbalancing actions should Washington take? Leaks are a fact of life — but why do they happen? Who gets them, and why? Should journalists publish or withhold them? Does legal accountability lie with the leaker—or the journalist?
This six-week course casts you as advisors on the hardest decisions any president has to make. We will go behind the veil to see the dynamic between the press and the U.S. government, to explore these dilemmas. We will also have to contend with the reality that government secrets rarely stay that way. Participants will learn to navigate the political landscape of an era in which private remarks become viral tweets, and mistakes by intelligence agencies become front-page stories.
Weekly assignments require strategic thinking: Analyzing dynamics of challenges and developing strategies for addressing them. Students will learn to summarize their analyses in a succinct “Strategic Options Memo,” combining careful analysis and strategic imagination with the necessity to communicate to major constituencies in order to sustain public support. They will also examine how policymaking is affected by constant, public analysis of government deliberations.

Physics 101 is the first course in the Introduction to Physics sequence. In general, the quest of physics is to develop descriptions of the natural world that correspond closely to actual observations. Given this definition, the story behind everything in the universe is one of physics. In practice, the field of physics is more often limited to the discovery and refinement of the basic laws that underlie the behavior of matter and energy. While biology is founded upon physics, in practice, the study of biology generally assumes that the present understanding of physical laws is accurate. Chemistry is more closely dependent on physics and assumes that physical laws provide accurate predictions. Engineering, for the most part, is applied physics. In this course, we will study physics from the ground up, learning the basic principles of physical laws, their application to the behavior of objects, and the use of the scientific method in driving advances in this knowledge. This first course o…
The physics of the Universe appears to be dominated by the effects of four fundamental forces: gravity, electromagnetism, and weak and strong nuclear forces. These control how matter, energy, space, and time interact to produce our physical world. All other forces, such as the force you exert in standing up, are ultimately derived from these fundamental forces. We have direct daily experience with two of these forces: gravity and electromagnetism. Consider, for example, the everyday sight of a person sitting on a chair. The force holding the person on the chair is gravitational, while that gravitational force is balanced by material forces that “push up” to keep the individual in place, and these forces are the direct result of electromagnetic forces on the nanoscale. On a larger stage, gravity holds the celestial bodies in their orbits, while we see the Universe by the electromagnetic radiation (light, for example) with which it is filled. The electromagnetic force also makes possible the a…
This course is designed to introduce you to the study of Calculus. You will learn concrete applications of how calculus is used and, more importantly, why it works. Calculus is not a new discipline; it has been around since the days of Archimedes. However, Isaac Newton and Gottfried Leibniz, two 17th-century European mathematicians concurrently working on the same intellectual discovery hundreds of miles apart, were responsible for developing the field as we know it today. This brings us to our first question, what is today's Calculus? In its simplest terms, calculus is the study of functions, rates of change, and continuity. While you may have cultivated a basic understanding of functions in previous math courses, in this course you will come to a more advanced understanding of their complexity, learning to take a closer look at their behaviors and nuances. In this course, we will address three major topics: limits, derivatives, and integrals, as well as study their respective foundations and a…
This course is the second installment of Single-Variable Calculus. In Part I (MA101) [1], we studied limits, derivatives, and basic integrals as a means to understand the behavior of functions. In this course (Part II), we will extend our differentiation and integration abilities and apply the techniques we have learned. Additional integration techniques, in particular, are a major part of the course. In Part I, we learned how to integrate by various formulas and by reversing the chain rule through the technique of substitution. In Part II, we will learn some clever uses of substitution, how to reverse the product rule for differentiation through a technique called integration by parts, and how to rewrite trigonometric and rational integrands that look impossible into simpler forms. Series, while a major topic in their own right, also serve to extend our integration reach: they culminate in an application that lets you integrate almost any function you’d like. Integration allows us to calculat…
This chemistry survey is designed to introduce students to the world of chemistry. The principles of chemistry were first identified, studied, and applied by ancient Egyptians in order to extract metal from ores, make alcoholic beverages, glaze pottery, turn fat into soap, and much more. What began as a quest to build better weapons or create potions capable of ensuring everlasting life has since become the foundation of modern science. Take a look around you: chemistry makes up almost everything you touch, see, and feel, from the shampoo you used this morning to the plastic container that holds your lunch. In this course, we will study chemistry from the ground up, learning the basics of the atom and its behavior. We will use this knowledge to understand the chemical properties of matter and the changes and reactions that take place in all types of matter.
