How much can we know of the physical world? Can we know everything? Or are there fundamental limits to how much we can explain? If there are limits, to what extent can we explain the nature of physical reality? RealityX investigates the limits of knowledge and what we can and cannot know of the world and ourselves.

We will trace the evolution of ideas about the nature of reality in philosophy and the natural sciences through the ages. Starting with the philosophers of Ancient Greece and ending with cutting edge theories about the universe, quantum physics, and the nature of consciousness.

Learners who complete this course will be able to:

A. Communicate with others about the latest scientific discoveries in various disciplines including cosmology, quantum physics, mathematics, machine intelligence and cognitive science.

B. Identify key points in history where scientific advances changed humanity’s philosophy and understanding of the nature of reality and our place in the Universe.

C. Reflect on and examine their own worldview and identify if any changes occurred during this course.

D. Confidently argue about scientific evidence, philosophical viewpoints, and others’ interpretations of both.

E. Demonstrate how the scientific method works, its limitations, and how scientists use it to construct knowledge about physical reality.

Join world-renowned physicist and author Marcelo Gleiser and leading experts as we explore how philosophers and physicists from Plato to Einstein and many others have attempted to explain the nature of the world and of reality.

This course will be offered in both English and Portuguese. Videos will have subtitles,discussions will be supported in both languages, as will all assignments.

In this seminar we will examine various issues related to the intersection of race and gender in Asian America, starting with the nineteenth century, but focusing on contemporary issues. Topics to be covered may include racial and gender discourse, the stereotyping of Asian American women and men in the media, Asian American masculinity, Asian American feminisms and their relation to mainstream American feminism, the debate between feminism and ethnic nationalism, gay and lesbian identity, class and labor issues, domestic violence, interracial dating and marriage, and multiracial identity.

This course explores the ways in which various American artists view race and class as performed or performable identities. Discussions will focus on some of the following questions: What does it mean to act black, white, privileged, or underprivileged? What do these artists suggest are the implications of performing (indeed playing at or with) racial identity, ethnicity, gender, and class status? How and why are race and class status often conflated in these performances?

This course examines one of the most enduring and influential forms of identity and experience in the Americas and Europe, and in particular the ways race and racism have been created, justified, or contested in scientific practice and discourse. Drawing on classical and contemporary readings from Du Bois to Gould to Gilroy, we ask whether the logic of race might be changing in the world of genomics and informatics, and with that changed logic, how we can respond today to new configurations of race, science, technology, and inequality. Considered are the rise of evolutionary racism; debates about eugenics in the early twentieth century; Nazi notions of "racial hygiene"; nation-building projects and race in Latin America; and the movement in modern biology from race to populations to genes and genomes.

This seminar looks at key issues in the historical development and current state of modern American criminal justice, with an emphasis on its relationship to citizenship, nationhood, and race/ethnicity. We begin with a range of perspectives on the rise of what is often called "mass incarceration": how did our current system of criminal punishment take shape, and what role did race play in that process? Part Two takes up a series of case studies, including racial disparities in the administration of the death penalty, enforcement of the drug laws, and the regulation of police investigations. The third and final part of the seminar looks at national security policing: the development of a constitutional law governing the intersection of ethnicity, religion, and counter-terrorism, and the impact of counter-terrorism policy on domestic police practices.

This course investigates the principles of thermal radiation and their applications to engineering heat and photon transfer problems.

Applications cover laser-material interactions, imaging, infrared instrumentation, global warming, semiconductor manufacturing, combustion, furnaces, and high temperature processing.

Have you ever wondered what it takes to get your train on the right platform at the scheduled time every day?

Understanding the complexity behind today’s sophisticated railway systems will give you a better insight into how this safe and reliable transportation system works. We will show you the many factors which are involved and how multiple people, behind the scenes, have a daily task that enables you to get from home to work. Journey with us into the world of rail - a complex system that connects people, cities and countries.

Railway systems entail much more than a train and a track. They are based on advanced technical and operational solutions, dealing with continuously changing demands for more efficient transport for both passengers and freight every day. Each system consists of many components that must be properly integrated: from trains, tracks, stations, signaling and control systems, through monitoring, maintenance and the impact on cities, landscape and people. This integration is the big challenge and the source of many train delays, inconvenient connections and other issues that impact our society.

This engineering course attempts to tackle those issues by introducing you to a holistic approach to railway systems engineering. You will learn how the system components depend on each other to create a reliable, efficient and state-of-the-art network.

We will address questions such as:

• How do railways work and how did they evolve over time?
• What factors give rise to everyday issues?
• How do different components of the railway system interact?
• What is the effect of train stations and the network from an urban, social and economic point of view?
• What can be done to improve the monitoring and maintenance of tracks?
• How are timetables designed in a way that balances passenger demand with the capacity of the railway and is adaptable to handle unexpected disturbances?
• What can be done to prevent and deal with disturbances caused by external factors and how do they affect the whole rail system?
• How does the design of railways influence their performance over time?

A new serious game has been designed for this course to guide you through the process of decision making while building a rail network and maintaining it. Cities have to be connected in an ever-changing setting, dealing with wear, capacity, developments and disturbances. What choices do you make and how do they affect the performance of the system?

For this MOOC, our very own TU Delft Measurement Train will be used to give you insights of the track and vehicle design, real-life monitoring and pantograph/catenary interaction. Together with the game this will give you the opportunity to see real-life examples and implement the knowledge you learn in a simulated environment.

This first ever MOOC on railway systems engineering is delivered by the renowned experts of TU Delft and leading professionals working in the industry. It combines theoretical knowledge with practical examples, with the main objective to maintain a high degree of reliability under predictable and unknown circumstances.

If you want to learn about the science behind the exciting world of railway systems - whether train, metro or tram - this course will set you on the right track!
