Size bir sır vermek istiyoruz: Yenilik sadece doktora öğrencileriyle dolu araştırma laboratuvarlarından çıkmıyor. Çoğunlukla yeniliği kendileri için önemli bir sorunu çözmek isteyen sıradan insanlar yaratıyor. Bunu siz de yapabilirsiniz.

Önce neye ihtiyacınız olduğunu düşünün. Sonra başkalarının da bunu isteyip istemediğini öğrenin. Eğer istiyorlarsa, önce kendiniz için geliştirdiğiniz bu yeni ürün veya hizmeti diğerlerine sunmak için kâr amaçlı veya kâr amaçlı olmayan bir girişim oluşturabilirsiniz.

Sonsuz sayıda kullanıcı yeniliği örneği var. Bir sörfçü, sörf yaparken selfie çekebilmek için GoPro'yu yarattı. Bir öğrenci flaş belleğini unuttuktan sonra Dropbox'ı buldu. İki parasız girişimci kirayı ödeyebilmek için salonlarını kiraya verince Airbnb ortaya çıktı. Girişimlerinin nasıl başarılı olduğunu bizimle paylaşacaklar.

Kullanıcı yeniliğini ortaya çıkaran profesör Eric von Hippel'ın verdiği bu derste hangi sorunları çözmeyi seçebileceğinizi ve yeniliklerinizi başkalarıyla nasıl paylaşabileceğinizi öğreneceksiniz.

Siz de yenilik yaratabilirsiniz.

We live in a time of disruptive change. How to activate our capacity to lean into the emerging future may well be the most important leadership challenge of our time. How do you cultivate curiosity, compassion and courage in the face of prejudice, anger and fear?

This course is an introduction to a method called Theory U, developed at MIT, for leading such change in business, government, and civil society contexts worldwide.

The only prerequisite for this course is u.lab 15.671.0x, an introductory overview--which you can complete in just 90 minutes. Building on the intention you set in u.lab 15.671.0x, 15.671.1x will help you to apply the Theory U method to an issue that matters to you, with fellow change makers locally and around the world. Join us as we co-pioneer new approaches to today’s most important social and environmental challenges using a method of awareness based systems change.

This course is the first course in a series of two. Both courses provide a solid foundation in the area of reliable distributed computing, including the main concepts, results, models and algorithms in the field.

Today's global IT infrastructures are distributed systems; from the Internet to the data-centers of cloud computing that fuel the current revolution of global IT services. At the core of these services you find distributed algorithms.

These algorithms run on multiple computers and communicate only by sending and receiving messages. It is crucial for the implemented services to continue to work 24/7 even if some of the computers fail or some of the messages are lost in transit. This is the subject of reliable distributed algorithms in computer science.

ID2203.1x covers models of distributed algorithms based on input/output automata; specifications of fault tolerant abstractions and failure detectors; specific distributed abstractions and fault-tolerant algorithms, including reliable broadcast and causal broadcast; key-value stores and consistency models; single-value consensus and the Paxos algorithm.

To complete the course with a full grade (100%) students are required to answer the graded quizzes provided every week, as well as the programming assignments.

Already know something about quantum mechanics, quantum bits and quantum logic gates, but want to design new quantum algorithms, and explore multi-party quantum protocols? This is the course for you!

In this history course, you will learn about the diversity and multilingualism that existed in Egypt, and how it had a bearing on the history of the country and its people.

Through the introduction of new languages, Egyptians learned to interact with scripts, cultures and peoples.

The plurality of languages and writing that Egypt witnessed along its history, gave rise to one of the most cosmopolitan melting pots in the ancient world. And although the peak of Egyptian multilingualism was in the Ptolemaic period [323-30 BCE], the country witnessed, in the pre-Ptolemaic period, the appearance of different foreign languages in official and public spheres.

This course examines and presents processes of designing and implementing land readjustment in the context of developing countries.

Land readjustment is an alternative land-assembly approach to government compulsory purchase (often referred to as eminent domain) and voluntary market transaction. In the land readjustment process, a public or private agency invites property owners to become stakeholders in a redevelopment project and to contribute their lands to the project as investment capital. In return, each property owner receives a land site of at least equal value in the vicinity of the original site upon project completion. After all properties in the district are assembled, the combined land sites are subdivided to make space for wider roads and other local infrastructure.

The conventional approaches to land assembly are often conflict-ridden. Through this course, practitioners can add another viable option to their toolbox by learning about land readjustment as an alternative approach to urbanization in developing countries.

Land readjustment has been shown to reduce the initial capital requirement for land assembly, discourage holdouts, and minimize massive relocation of existing residents. When applying land readjustment at the right time and in the right place, this approach could mediate a major hindrance of land redevelopment in countries that are facing rapid urbanization.      

The goal of this mathematics course is to provide high school students and college freshmen an introduction to basic mathematics and especially show how mathematics is applied to solve fundamental engineering problems.

Feeding nine billion people in 2050 without exhausting the planetary reserves is perhaps the greatest challenge mankind has ever faced. This environmental studies course will examine the principles of production ecology and the ‘availability pillar’ of global food security that lie at the heart of food production, which can be applied to both crops and animal production. This course will discuss why yields in some parts of the world are lagging behind and identify the agro-ecological drivers that shape the wide diversity of production systems.

Furthermore, key issues relating to the closing of yield gaps and the difference in visions of sustainability will be explored.

This online course will be of great interest to international students and those with varied educational backgrounds, both professionally and culturally, to enrich their views and action perspectives related to global food security and food systems. Professor Ken E. Giller will introduce learners to crop production and underlying bio-physical principles in order to identify constraining factors in yield formation. He will explain how to assess yield gaps at the level of fields and production systems around the world, contributing to efficient resource management. Wageningen University and Research, through its unique systems-based approach to food systems, adds the phase of primary production to the broad context of global food security.

Today, you are the law.

What does it mean to be a citizen? It means to participate in your society, to connect with others, and to decide, with them, the issues that you face.

It starts with you.

We need to learn to talk civilly with each other about the issues of consequence, but are we capable of learning how to speak together, listen together, and decide together?

In JuryX: Deliberations for Social Change, an experiment in online civic discourse, you are invited to engage with Professor Nesson and others with an understanding that each of us starts from a place of anonymity. Through a series of asynchronous and synchronous online group activities, you will explore a deliberative system by which emotionally charged issues can be discussed.

Although you will learn a bit about the history of jury and even serve as a member of a virtual jury for a mock criminal case, this experiment is about active participation in the deliberative process and how you might use that framework to facilitate dialogue within your own affinity group or community.

The program consists of six modules. Each week, you will learn and apply a new step in a system designed to foster meaningful dialogue. Starting with an introduction to the course’s deliberative framework, you will move from a traditional jury-based application to a live social issue unfolding in real time: the Massachusetts referendum for the “Legalization, Regulation, and Taxation of Marijuana.” As citizens of the Commonwealth of Massachusetts deliberate on this issue, so will you and your JuryX peers. What arguments will shape this debate, and what will the final outcome be?

Can we, civilly, discuss an issue like marijuana regulation?

Two synchronous small-group online deliberations will be held using Google Hangout. Participation is optional, but highly recommended.

JuryX: Deliberations for Social Change is, ultimately, about the most fundamental of human interactions: communication. By listening, speaking, persuading, and being persuaded, you will learn about yourself and others.

If you have faith, faith will be given to you.
