Lastly, you will learn about the addition of angular momentum and an algebraic approach to the hydrogen atom spectrum.

This is the last of three courses offering a sophisticated view of quantum mechanics and its proper mathematical foundation.

• Part 1: Wave Mechanics
• Part 2: Quantum Dynamics
• Part 3: Entanglement and Angular Momentum

To follow this course you should have taken Part 1: Wave Mechanics, and Part 2: Quantum Dynamics.

Completing the 3-part Quantum Mechanics series will give you the necessary foundation to pursue advanced study or research at the graduate level in areas related to quantum mechanics

The series will follow MIT’s on campus 8.05, the second semester of the three-course sequence on undergraduate quantum mechanics, and will be equally rigorous. 8.05 is a signature course in MIT's physics program and a keystone in the education of physics majors. 

Learner Testimonials

“I’ve thought long and hard to come up with a better MOOC than this one (I’ve completed 25 of these things over the past 2 years) and can’t do it. 8.05x is #1 and I suspect will stay that way for some time to come.”

 “Being an engineering student from India trying to shift to Physics, I am often faced with the requirement to study topics on my own. Very often this has led me to feel inadequate. 8.05x was the perfect opportunity for me to both gain knowledge and evaluate my understanding on a high quality international platform. It has really exceeded my expectations. Now, at the end of fifteen weeks, I feel more confident and hopefully I am more knowledgeable.”

There are underlying fundamental principles and concepts that apply to all supply chains, which can be expressed in relatively straightforward models. However, to actually implement them across a real supply chain requires the use of technology across multiple systems. Supply chains have a long history of using technology to improve efficiency and effectiveness. The shear scale and scope of most supply chains require many distinct systems to interact with each other.

Unfortunately, technology is a moving target. It is constantly evolving and improving so that today’s technology is outdated within a few years or months. Rather than focusing on a specific software system, this business and management course will focus on three aspects: fundamental concepts, core systems, and data analysis.

We will start with the introduction of fundamental concepts that are used in all software tools. We will cover IT fundamentals, including project management and software processes, data modeling, UML, relational databases and SQL. We will also introduce Internet technologies, such as XML, web services, and service-oriented architectures. No prior programming experience required.

We will then provide an overview of the main types of supply chain software including ERP, WMS, and TMS systems. We will describe their main functionality, how they work, how they are used, their architecture, data flows, and how they are organized into modules. We will also cover the software selection process and how software upgrade and implementation projects should be organized and managed.

Finally, we will dive into data analysis that is core to all large supply chains. We will introduce visualization and big data analysis techniques that are used in practice today.

This course will explain what marketing management is all about in the simplest of terms and lay the foundation to your pathway to excellence in the wonderful world of marketing.

International Politics in the Korean Peninsula reviews several archetypes of politics and introduces contemporary issues of the inter-Korean relationship. Video lectures will be in Korean, with English subtitles. Discussions, quizzes, and other course content will be in English. This course is the first part of International Politics in the Korean Peninsula; the second part will start this Fall.

The course is introduced with two cases where politics brought tragedies: the hyper-inflation in Zimbabwe and the political idolization in North Korea. These two cases provide a good answer to why we study politics.

The central content of the course is organized into two modules. First, it will start with several chapters from Records of the Grand Historian (Chinese: 史記), Plutarch's Lives, and History of the Three Kingdoms (한국어: 삼국사기; Chinese: 三國史記) to find out four archetypes of politics: value creation/distribution in a political entity, conflict and cooperation among political entities, development and maintenance of an identity in a political entity, and leadership selection in an entity.

The second module of the course will link the four archetypes of politics with contemporary issues of inter-Korean politics and political events in North Korea. These issues will include the Korean Crisis in 2012, the arms race between the two Koreas, the power succession and the simultaneous (nuclear and economic) build-up strategy in North Korea, and upcoming political events.

Course videos are presented in Korean with English subtitles.

Vision may feel effortless: you open your eyes, and the world appears. But the process of focusing light into image on the back of the eye and translating it into meaningful nerve signals is incredibly complex. The retina and visual cortex are packed with intricate processing circuitry, and have been a mystery to neuroscientists for centuries. Now, answers are beginning to emerge.
 
Today, the visual system is often called the model system for neuroscience: its findings are relevant to all other areas and to investigating the deeper mysteries of the brain’s microstructure and function. In this course, we take you from the physics of focusing light onto the retina, to the processing of colors, form, and motion, and finally to the interpretation of visual information in the cortex. We distill the mysteries of the visual system by posing questions and investigating them in a series of thematic, animated videos. This journey through the eye, retina and brain will (quite literally) change how you see the world.

Composites are used in many industries today to enable high-performance products at economic advantage. These industries range from space to sports and include manufactured products for aircraft, transportation, energy, construction, sports, marine, and medical use. There are many material, economic and aesthetic advantages to using composites, but a solid knowledge of the physical properties, including the mechanics, tooling, design, inspection & repair, and manufacturing options is required for working in this medium as they are intrinsically linked.

This course provides an introduction to the fundamentals of composite materials for high performance structures from the point of view of Aerospace engineering design, manufacturing, and repair. It is designed to address critical areas of composite technologies that focus on materials, manufacturing, mechanics, design, inspection, and repair.  In this course students will learn how composite materials achieve properties of strength, weight ratios and durability that surpass aluminum in aircraft design.  For these high performance applications engineers typically rely on laminated structures, which are built up from many varying layers of ply-materials. Using this process the mechanical properties of the composite part can be tailored to specific applications resulting in significant weight and cost savings. Tailoring specific properties and designing innovative laminate structures highlights the multidisciplinary nature of this industry and how it touches the expertise of many disciplines including engineers, mechanics, and inspection specialists.

After successfully completing this course, students will be able to identify the unique characteristics of composites and understand how advanced composite structures are designed, manufactured and maintained.

There is no doubt that technological innovation is one of the key elements driving human progress.

However, new technologies also raise ethical questions, have serious implications for society and the environment and pose new risks, often unknown and unknowable before the new technologies reach maturity. They may even lead to radical disruptions. Just think about robots, self-driving vehicles, medical engineering and the Internet of Things.

They are strongly dependent on social acceptance and cannot escape public debates of regulation and ethics. If we want to innovate, we have to do that responsibly. We need to reflect on –and include- our societal values in this process. This course will give you a framework to do so.

The first part of the course focuses on ethical questions/framework and concerns with respect to new technologies.

The second part deals with (unknown) risks and safety of new technologies including a number of qualitative and quantitative risk assessment methods.

The last part of the course is about the new, value driven, design process which take into account our societal concerns and conflicting values.

Case studies (ethical concerns, risks) for reflection and discussions during the course include – among others- nanotechnology, self-driving vehicles, robots, AI smart meters for electricity, autonomous weapons, nuclear energy and CO2capture and coolants. Affordable (frugal) innovations for low-income groups and emerging markets are also covered in the course. You can test and discuss your viewpoint.

The course is for all engineering students who are looking for a methodical approach to judge responsible innovations from a broader – societal- perspective.

Life on our planet is diverse. While we can easily recognize this in our everyday surroundings, an even more diverse world of life can be seen when we look under a microscope. This is the world of microorganisms. Microorganisms are everywhere, and although some are notorious for their roles in human disease, many play important roles in sustaining our global environment. Among the wide variety of microorganisms, here we will explore those that thrive in the most extreme environments, the extremophiles.

In this course, we will discover how diverse life is on our planet and consider the basic principles that govern evolution. We will also learn how we can classify organisms. Following this, we will have a look at several examples of extreme environments, and introduce the microorganisms that thrive under these harsh conditions. We will lay emphasis on the thermophiles, extremophiles that grow at high temperatures and will study how proteins from thermophiles can maintain their structure and function at high temperatures.

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.

This mini-course focuses on the question of accountability in public schools.

Who is accountable for student outcomes? Should we blame the schools or hold the students themselves accountable? Who determines the standards for accountability – the federal government or the individual states?

The demand for accountability in U.S. education resulted in No Child Left Behind and has shaped the Common Core debate. Throughout this mini-course, we will trace the origins of the accountability movement, the increased role of the federal government, the design of accountability interventions, and the impact of accountability programs on student performance.

This mini-course contains five lectures, with most lectures divided into three videos. The mini-courses also include assigned readings, discussion forums, and assessments.

This is the third mini-course in a four-course sequence.

• Mini-Course 1: History and Politics of U.S. Education
• Mini-Course 2: Teacher Policies
• Mini-Course 3: Accountability and National Standards
• Mini-Course 4: School Choice

course-v1:HarvardX+1368.3x+2T2016
