History of mathematics and X
The History of Mathematics and X "is an initiative that aims to offer mathematical histories for various topics, x. Each topic is covered in a talk at the University of Nottingham that is available to view online, in an article for iSquared Magazine and is accompanied by a companion podcast released by the Institute of Mathematics and its Applications through the Travels in a Mathematical World podcast." Two topics are currently (May 2010) available - cryptography and gravity. These resources ha

Virtual Reality: an approach for building Makkah?s architectural identity
This paper explores a new approach in the architectural design process aiming to construct Makkah's architectural identity. Makkah, which is a city of unique sacred values, has been losing its battle to preserve it heritage buildings. Traditional districts with their heritage buildings have been cleared in order to construct skyscrapers to accommodate the increasing number of pilgrims. While some argue for preserving heritage buildings others insist in building more skyscrapers. Within these con

Elizabeth Norton, Ph.D.: Using simultaneous EEG-fMRI to characterize human face processing in space
A key feature of the human social brain is its specialized ability to process faces. EEG and fMRI brain imaging studies have yielded conflicting results about whether the brain's response to faces is qualitatively or quantitatively different in individuals with autism spectrum disorders (ASDs). Here, I present data from a study using simultaneous EEG-fMRI to relate the EEG/ERP time course of face processing to the associated fMRI activation in adults with and without ASD. This approach is novel

18.755 Introduction to Lie Groups (MIT)
This course is devoted to the theory of Lie Groups with emphasis on its connections with Differential Geometry. The text for this class is Differential Geometry, Lie Groups and Symmetric Spaces by Sigurdur Helgason (American Mathematical Society, 2001). Much of the course material is based on Chapter I (first half) and Chapter II of the text. The text however develops basic Riemannian Geometry, Complex Manifolds, as well as a detailed theory of Semisimple Lie Groups and Symmetric

1.5 Tips on character creation

  • Use a journal to build ideas for character.

  • Consider all the influences that go into the making of your character: age, gender, race, nationality, marital status, religion, profession.

  • Know about your character's inner life: what s/he wants, thinks, remembers, resents, fears, dreams, denies.

  • Know about your character's behaviour, what s/he wears, buys, eats, says, works at and plays at.

2.6 Lines

Earlier, we found the equation of a line in the (x, y)-plane in the form ax + by = c, for some real numbers a, b and c, where a and b are not both zero. We now find an equivalent equation for a line in terms of vectors.

Let P and Q be two given points with position vectors p and q, and denote by ℓ the line that passes through P and Q. How can we find the position vector

Introduction

This course will look at how pictures and diagrams can be used to represent information and ideas. In mathematics, science and technology (MST) subjects, we can often summarise how ideas or processes are connected much more neatly in a diagram than in words, or we can show how something looks and works by drawing a picture of it. This means that, as a learner, you need to be comfortable with pictures and diagrams. You need to learn how to read them – how to extract information from t
