- L01: TR2-330 – Redwine
- The existential threat posed by the existence and deployment of large numbers of nuclear weapons is understood and appreciated by some members of our society, but certainly not by all. The presenters of this subject, all of whom have considerable relevant knowledge concerning nuclear weapons, plan to discuss important issues about the history and future prospects for the deployment of nuclear weapons that will help students understand options for reducing this existential threat. We hope that the subject will be attractive to a wide range of students, both undergraduate and graduate students, from Departments across MIT. In addition to the material presented in lectures, there will be important reading and writing assignments, as well as in-class group activities. After completing this subject, students should be very knowledgeable about the history and current threats of nuclear weapons as well as about realistic ways to reduce or eliminate these threats.
