EECS149.1x introduces students to the design and analysis of computational systems that are integrated with physical processes.

8.EFTx is an online version of MIT's graduate Effective Field Theory course. The course follows the MIT on-campus class 8.851 as it was given by Professor Iain Stewart in the Fall of 2013, and includes his video lectures, resource material on various effective theories, and a series of problems to facilitate learning the material. Anyone can register for the online version of the course. When the course is being taught on campus, students at MIT or Harvard may also register for 8.851 for course credit.

Effective field theory (EFT) provides a fundamental framework to describe physical systems with quantum field theory. In this course you will learn both how to construct EFTs and how to apply them in a variety of situations. We will cover the majority of the common tools that are used by different effective field theories. In particular: identifying degrees of freedom and symmetries, formulating power counting expansions (both dimensional and non-dimensional), field redefinitions, bottom-up and top-down effective theories, fine-tuned effective theories, matching and Wilson coefficients, reparameterization invariance, and various examples of advanced renormalization group techniques. Examples of effective theories we will cover are the Standard Model as an effective field theory, integrating out the massive W, Z, Higgs, and top, chiral perturbation theory, non-relativistic effective field theories including those with a large scattering length, static sources and Heavy Quark Effective Theory (HQET), and a theory for collider physics, the Soft-Collinear Effective Theory (SCET).

Course Flow

Since this is an advanced graduate physics course, you will find that self-motivation and interaction with others is essential to learning the material. The purpose of the online course is to set you up with a foundation, to teach you to speak the language of EFT, and to connect you with other students and researchers that are interested in learning or broadening their exposure to this subject. Each week you will complete automatically graded homework problems to test your understanding and to help you master the material. You are expected to discuss the homework with other people in the class, but your online responses must be done individually. To facilitate these interactions there will be a forum for student-to-student discussions, with threads to cover different topics, and moderators with experience in this field. Student learning and discussions will also be prompted by questions posed after each lecture topic.

There will be no tests or final exam, but at the end of the course each student will give a 30-minute presentation on an EFT topic of their choosing. The subject of effective field theory is rich and diverse, and far broader than we will be able to cover in a single course. The presentations will create an opportunity for you to learn about additional subjects beyond those in lecture from your fellow students. To facilitate this learning opportunity, each student will be required to watch and grade five presentations from among their fellow students.

Since this is a graduate course, we anticipate that learning the subject and having the 8.EFTx materials available as an online resource will be more valuable to most of you than obtaining a grade. Therefore anyone who registers for the course will be able to retain access to the course materials after the course has ended. Note that when the course is archival mode that the problems can be attempted and checked in the same manner as when the course was running.

In this education and teacher training course we will explore effective teaching methods for biology. We will emphasize approaches proven to be effective and show you how to implement them. We will also give you the opportunity to reflect on your own teaching experience and exchange ideas and share challenges with other learners in the course.

We will begin by looking at the most common method of teaching science, the lecture. We’ll discuss what the lecture method does well and look at data that illustrates when it is less effective. You will hear highly successful teachers talk about their experience with lecture and how they modified their lecture time to more actively engage students. We’ll investigate creating learning objectives and how they can be used to communicate your expectations to students. You will practice writing your own learning objectives and see how they can streamline exam construction. We’ll look at a variety of ways to include active learning during class time, discuss how active learning strategies support your learning objectives, and give you practice developing learning activities for biology topics you find challenging to teach. 

Lastly, we’ll look at how to use resources for student learning outside of class, and how to know that your students have successfully learned from both in-class and outside of class activities.

Our course is designed for instructors, or instructors-to-be, of undergraduate-level biology. High school instructors of AP Biology, post-doctoral fellows and graduate students looking ahead to teaching should find the course useful. The course can serve as a means of professional development. There are no pre-requisites, although prior satisfactory completion of a college biology course is highly recommended.

A wondrously romantic belief is that brilliant thinkers magically produce brilliant ideas: Einstein jostles his hair and relativity falls out. We can enjoy these fanciful visions of leaps of genius, but we should not be fooled into believing that they’re reality.

Brilliant innovators are brilliant because they practice habits of thinking that inevitably carry them step by step to works of genius. No magic and no leaps are involved.

Professor Starbird will discuss how habits of effective thinking and creativity can be taught and learned through puzzles and mathematics. Anyone who practices these habits of mind will inevitably create new insights, new ideas, and new solutions.

There are many practical applications of radiation and radioactivity in various fields, including medical, scientific, and industrial activities. In some parts of Japan, people continue to experience environmental radioactivity caused by the nuclear accident at the Fukushima Daiichi Nuclear Power Plant on a daily basis. Understanding the basic science of radiation and radioactivity will form the base of the course, with specific examples from Japan and elsewhere in the world to illustrate concepts.

This course introduces radiochemistry, radiation detection and measurement, and explores radiation’s effect on the human body. You will gain a greater understanding of radioisotopes, radioactive decay, radiations, radiation interaction with matter, and ways to assess radiation exposure. We will explore applications of radiation through various examples including nuclear power generation, diagnostic and therapeutic uses in medicine, and other scientific and industrial uses. Lastly, we will discuss the fate and transport of radioactive cesium in Fukushima in relation to chemical and physical properties of the radionuclide.

KIeHealthX will introduce students to the field of eHealth and its opportunities and challenges. During the course you will get to know the different concepts that are used in the field and learn how it developed historically. This basic knowledge will help you to understand the opportunities and challenges of the field. You will meet different stakeholders from various countries and get to know their views on the opportunities and challenges of eHealth. We will introduce you to eHealth strategies and frameworks for developing and analyzing them. You will get to know methods for eHealth service development and discuss basic requirements that are necessary to achieve sustainable eHealth applications for both clinical professionals and patients.

You will see examples of eHealth applications in different contexts and for different users. We will discuss questions such as:

• What is it that is so unique about the health sector?
• What factors are important - to avoid failures when implementing eHealth?
• What are usable tools for care professionals?
• How can patients best organize and use their own health data to improve their condition?

eHealth is a global issue but successful eHealth implementation is very dependent on the local context. At the end of the course you will have a basic understanding what eHealth is and how to set up eHealth strategies and discuss them in your specific context. You will also get to know success factors and pitfalls for the development of sustainable eHealth services and their implementation. 

This course is offered in collaboration with EIT Health.

PHYS 102.1x serves as an introduction to electricity and magnetism, following the standard second semester college physics sequence. Part 1 begins with electric charge in matter, the forces between charges, the electric field, Gauss’s Law, and the electric potential. Electric current and resistance are introduced, and then DC circuits are described, including time-dependent behavior with resistors and capacitors. PHYS 102.1x consists of 5 weekly learning sequences, each with ~1.5 hours of video lectures, conceptual lecture problems, and online homework questions. The course concludes with an online exam during the 6th week.  

What are the prerequisites?
We will assume that you are familiar with vectors, that you know how to calculate integrals, and that you have had introductory mechanics. These topics will be briefly reviewed as needed, but not in a systematic way. If you have not had classes in these topics it may be possible to complete the course with extra study.

What textbook is required?
The course will not strictly follow or make assignments from a specific textbook.  Any recent freshman physics textbook will suffice. Reading assignments will be given by topic, including links to several free online physics textbooks.

The course concludes with an online exam during the 6th week. 

EE40LX teaches the fundamentals of engineering electronic interfaces between the physical world and digital devices. Students can expect to cover the material of a traditional first circuits course with a project-based approach. We start with essential theory and develop an understanding of the building blocks of electronics as we analyze, design, and build different parts of a robot from scratch around a microcontroller. This course uses the Texas Instruments MSP430G2 LaunchPad, but you are welcome to bring whichever development board or microcontroller you like!

Useful mathematics will be discussed where appropriate, but only a working knowledge of high school algebra is required to follow along for most of the course. The philosophy of the course is to learn by doing, so every lecture features a substantial lab component. Students are invited to work together in small groups to build their own robots along with the instructors. There will also be individual circuit analysis and design exercises to reinforce the theories presented in the course. Those who successfully complete each theory assignment and earn a passing grade will get an Honor Code certificate from BerkeleyX.

Additionally, a kit of electronic components will be available from Newark element14 starting June 12. The kit is not necessary to obtain a certificate for this run of the course, but it will greatly enhance your learning experience. Some mechanical components are required to complete the robot as presented in the course. Also, the lab experience will be most effective if you have access to a digital multimeter.

Creativity is encouraged! Students who are willing to work outside the bounds of the class to develop their own inventions will get the most out of this guided learning experience.

MyDAQ Information
Those who do not have access to an oscilloscope or a digital multimeter might consider purchasing a MyDAQ to enable measurements. The video modules use the MyDAQ and the MyProtoBoard as measurement equipment to debug circuits. National Instruments has made available the MyDAQ for students in this course. If you are interested, take a look at the MyDAQ ordering page: http://www.studica.com/us/en/BerkeleyMOOC.html

Parts Kit Information
The parts included in the construction of the robot can be purchased at Newark's landing page, which can be found here: http://www.element14.com/community/community/learning-center/online-learning/moocs/edxucb-bridging

A detailed bill of materials with more information can be found here: courses.edx.org/asset-v1:BerkeleyX+EE40LX+2T2015+type@asset+block@EE40LX_PartsList_Summer15.pdf

What is the format of the class?
The class consists of eight modules. Every module consists of a combination of theory-based lectures and lab-based discussions where we apply that module’s theory to building a part of a robot. Quiz exercises are sprinkled throughout the videos to reinforce your knowledge and every module ends with a problem set that reinforces the design and analysis aspects of the class.

Is this class taught at UC Berkeley?
This class is part of the laboratory component of "EE40: Introduction to Microelectronic Systems," the first circuit analysis course at UC Berkeley. It was specifically designed for the online course format.

What will the robot do?
The bare-bones robot that we build will be capable of bouncing around, responding to light or touch inputs, and responding to a loud audio signal.

What supplies and equipment will I need to get the most out of this course?
In order to download programs to the MSP430 microcontroller, you will need access to a modern operating system (Apple, Windows, or Linux) with the Energia environment (http://energia.nu/download) installed. Additionally, access to some wire cutters and pliers would be useful. Also, the lab experience will be most effective if you have access to a digital multimeter. An oscilloscope would be useful, but not necessary.

The NI MyDAQ has been made available for students who would like to follow along with the course. The robot project as presented also requires a few wooden craft sticks and two springs which can be found at a local hardware store.

How much does the kit cost?
The parts kit will cost around $50 USD for most parts. You are welcome to purchase a kit with another student and to work together on labs to split costs. We will also demonstrate other parts not in the kit for those interested in extending their projects.

Will I need to know how to program?
Sample programs are provided in each module that will allow you to test your own circuits with an MSP430 LaunchPad controller. These programs will be explained in optional videos for interested students. If you already know how to code, you can tweak these programs to add additional functionality to your project.

Will this course cover microcontroller programming?
No. Sample programs written in Energia, a high-level language, will be provided, but programming will not be explicitly covered. Students interested in learning microcontroller programming should refer to UT Austinx’s Embedded Systems course.

What if I already have a microcontroller?
Since analog electronics are the emphasis of the course, you should feel free to use any microcontroller you feel comfortable with. However, the use of any other microcontrollers would require you to write your own programs.

Is there a required textbook?
No textbook is required for this course. Handouts are provided for the concepts presented in the class; material for some of these handouts is taken from the 2nd edition of the book Circuits by Fawwaz Ulaby and Michel Maharbiz and we recommend the book as way to delve deeper into basic circuit concepts. We also occasionally provide links to web content that we find useful or informative.

Love letters generated by a computer. An online poem two hundred trillion stanzas long. A mystery novel in the form of a wiki. The story of Inanimate Alice, told through videos and instant messages. An ocean buoy tweeting remixes of Moby Dick. Welcome to the weird world of electronic literature—digitally born poetic, narrative, and aesthetic works read on computers, tablets, and phones. Experimental, evocative, and sometimes simply puzzling, electronic literature challenges our assumptions about reading, writing, authorship, and meaning.

Yet e-lit, as it is often called, has also profoundly influenced mainstream culture. Literature, film, comics, apps, and video games have all learned lessons from electronic literature. This course will trace the rise of electronic literature and explore both historic and contemporary works of e-lit. We’ll begin with electronic literature’s roots in avant-garde art and Cold War technology, and follow e-lit through the birth of the personal computer into the era of the Web and smartphone. At every step along the way the expressive power of new media—the way digital media enables and shapes different modes of creative and cultural expression—will be of particular interest to us.

Courses offered via edX.org are not eligible for academic credit from Davidson College. A passing score in a DavidsonX course(s) will only be eligible for a verified certificate generated by edX.org.

Ce cours définit les notions de base des circuits électriques composés des trois éléments passifs (résistance, inductance et condensateur), linéaires et des sources de tension et de courant.

On traite ces circuits avec les lois élémentaires de l'électricité puis on développe une série de méthodes de combinaisons des éléments et de transformations du circuit qui mènent à leur simplification et permettent une analyse aisée des courants, tensions et puissances présents. Quelques circuits particuliers classiques sont présentés. 

Toutes ces méthodes sont premièrement développées en régime continu puis elles sont généralisées au régime alternatif, faisant intervenir le calcul complexe. L'importance du régime alternatif réside dans le fait qu'il est omniprésent au niveau de la distribution électrique domestique et industrielle.

This course is presented in French.

This course is presented in French, with English subtitles.

Ce cours traite des systèmes alternatifs triphasés, piliers de l'alimentation électrique industrielle et de certains types de machines électriques. Les charges triphasées associées, symétriques ou dissymétriques, seront étudiées ainsi que les puissances actives, réactives et apparentes qui en découlent. Des méthodes de compensation de la puissance réactive seront développées.

Ce cours traite également des régimes transitoires, induits par les enclenchements, déclenchements ou pannes de circuits sur leur source, qu'elle soit continue ou alternative. L'importance de l'étude des régimes transitoires réside dans le fait qu'ils sont la base du fonctionnement d'appareils que l'on retrouve dans de nombreuses applications modernes comme la distribution d'énergie, les entraînements électriques, la recharge de batteries, les alimentations à découpage ou encore de l'éclairage.
