18.03 Differential Equations (MIT) 18.03 Differential Equations (MIT)

Description

Differential Equations are the language in which the laws of nature are expressed. Understanding properties of solutions of differential equations is fundamental to much of contemporary science and engineering. Ordinary differential equations (ODE's) deal with functions of one variable, which can often be thought of as time. Topics include: Solution of first-order ODE's by analytical, graphical and numerical methods; Linear ODE's, especially second order with constant coefficients; Undetermined coefficients and variation of parameters; Sinusoidal and exponential signals: oscillations, damping, resonance; Complex numbers and exponentials; Fourier series, periodic solutions; Delta functions, convolution, and Laplace transform methods; Matrix and first order linear systems: eigenvalues and Differential Equations are the language in which the laws of nature are expressed.

A numbers game: counting refugees and international burden-sharing

Description

Public Seminar Series, Hilary term 2013. Seminar by dr Alice Edwards (UNHCR) recorded on 13 February 2013 at the Oxford Department of International Development, University of Oxford. The United Nations Refugee Convention recognises that the problem of refugees is inherently international and cannot be solved by a single State alone. Yet achieving international cooperation, or even achieving consensus on what this means, has had a long and chequered history. This lecture will examine the many ways in which a focus on asylum statistics has impacted on the international protection regime for refugees, and what needs to be done about it.

18.409 Behavior of Algorithms (MIT) 18.409 Behavior of Algorithms (MIT)

Description

This course is a study of Behavior of Algorithms and covers an area of current interest in theoretical computer science. The topics vary from term to term. During this term, we discuss rigorous approaches to explaining the typical performance of algorithms with a focus on the following approaches: smoothed analysis, condition numbers/parametric analysis, and subclassing inputs.

21L.458 The Bible (MIT) 21L.458 The Bible (MIT)

Description

This course is an introduction to major books from both the Hebrew Bible and the New Testament. Particular attention has been given to literary techniques, issues resulting from translation from the original Hebrew and Greek, and the different historical periods that produced and are reflected in the Bible. Investigation of the Bible as influence in later narrative, philosophic, and artistic traditions. This course is an introduction to major books from both the Hebrew Bible and the New Testament.

18.S66 The Art of Counting (MIT) 18.S66 The Art of Counting (MIT)

Description

The subject of enumerative combinatorics deals with counting the number of elements of a finite set. For instance, the number of ways to write a positive integer n as a sum of positive integers, taking order into account, is 2n-1. We will be concerned primarily with bijective proofs, i.e., showing that two sets have the same number of elements by exhibiting a bijection (one-to-one correspondence) between them. This is a subject which requires little mathematical background to reach the frontiers of current research. Students will therefore have the opportunity to do original research. It might be necessary to limit enrollment. The subject of enumerative combinatorics deals with counting the number of elements of a finite set.
