Phase transformation from an isotropic liquid to a chiral nematic liquid crystal
Phase transformation (20x magnification, 3x speed) for an isotropic liquid to chiral nematic liquid crystal. Although nucleation begins in a similar fashion to the regular nematic, we can see the different regions merge with one another to form the final 'fingerprint structure' that is characteristic of chiral nematics with their helical axis parallel to the surface of the slide.

Growth of a two-dimensional grain structure
A Voronoi diagram is created using Surface Evolver, from a random set of (N=1000) points to represent the grain structure. The boundary length is then minimised, subject to the constraint of constant area. The video shows the growth of a two-dimensional grain structure: From TLP: Grain growth, http://www.doitpoms.ac.uk/tlplib/grainGrowth/2dcomputersimulation.php
5.61 Physical Chemistry (MIT)
This course presents an introduction to quantum mechanics. It begins with an examination of the historical development of quantum theory, properties of particles and waves, wave mechanics and applications to simple systems — the particle in a box, the harmonic oscillator, the rigid rotor and the hydrogen atom.

International Classification of Function, Disability and Health
This package was originally designed for undergraduates in Medicine at the University of Nottingham. It will also be useful to students in nursing, allied health professions and pharmacy. Practitioners in these fields, who are new to the ICF, will also find it a useful introduction. It describes the International Classification of Functioning, Disability and Health (ICF), a classification system published by the World Health Organisation to describe health status. This system is widely used in r
Carbon-carbon composite
Carbon-carbon composites are manufactured from continuous carbon fibres which are woven in a two or three dimensional pattern. The fibres are then impregnated with a polymeric resin. After the component has been shaped and cured the matrix is pyrolysed by heating in an inert atmosphere. This converts the matrix to carbon chain molecules which are densified by further heat treatments. The resulting composite consists of the original carbon fibres in a carbon matrix. Carbon-carbon composites have

As-cast wrought-grade aluminium alloy
The micrograph shows Al-Mg-Fe-Si containing < 1wt.% of each solute. No addition of grain refinement particles (e.g. TiB2). This micrograph illustrates one of the possible growth morphologies that a solidifying metal can adopt (c.f. micrograph 712). The dendritic structure is the result of instabilities in the solid-liquid interface during growth due to the rejection of solute into the liquid phase. Dendritic grains are more prevalent in alloys of high solute content and larger grain sizes.The Ba
Article :: Adobe® Flash® Catalyst™ CS5 Classroom in a Book: Preparing a Design Documen
The way you approach the design and organization of your artwork has a significant impact on the structure of the project in Flash Catalyst and the underlying code. This excerpt from Adobe® Flash® Catalyst™ CS5 Classroom in a Book will help protect the integrity of your design and minimize re-working or re-structuring assets after bringing them into Flash Catalyst.

6.912 Introduction to Copyright Law (MIT)
This course is an introduction to copyright law and American law in general. Topics covered include: structure of federal law; basics of legal research; legal citations; how to use LexisNexis®; the 1976 Copyright Act; copyright as applied to music, computers, broadcasting, and education; fair use; Napster®, Grokster®, and Peer-to-Peer file-sharing; Library Access to Music Project; The 1998 Digital Millennium Copyright Act; DVDs and encryption; software licensing; the GNU® General
21W.765J Interactive and Non-Linear Narrative: Theory and Practice (MIT)
This course covers techniques of creating narratives that take advantage of the flexibility of form offered by the computer. The course studies the structural properties of book-based narratives that experiment with digression, multiple points of view, disruptions of time and of storyline. The class analyzes the structure and evaluates the literary qualities of computer-based narratives including hypertexts, adventure games, and classic artificial intelligence programs like Eliza. With this base
11.301J Introduction to Urban Design and Development (MIT)
This course examines both the structure of cities and ways they can be changed. Its scope includes historical forces that have produced cities, models of urban analysis, contemporary theories of urban design, and implementation strategies. Core lectures are supplemented by discussion sessions focusing on student work and field trips. Guest speakers present cases involving current projects illustrating the scope and methods of urban design practice.
2.001 Mechanics & Materials I (MIT)
This course provides an introduction to the mechanics of solids with applications to science and engineering. We emphasize the three essential features of all mechanics analyses, namely: (a) the geometry of the motion and/or deformation of the structure, and conditions of geometric fit, (b) the forces on and within structures and assemblages; and (c) the physical aspects of the structural system (including material properties) which quantify relations between the forces and motions/deformation.
17.50 Introduction to Comparative Politics (MIT)
This class first offers some basic analytical frameworks - culture, social structure, and institutions - that you can use to examine a wide range of political outcomes. We then use these frameworks to understand (1) the relationship between democracy and economic development and (2) the relative centralization of political authority across countries. We will use theoretical arguments and a wide range of case studies to address several questions: Why are some countries democratic and others not?
9.93 Marathon Moral Reasoning Laboratory (MIT)
This seminar focuses on the cognitive science of moral reasoning. Philosophers debate how we decide which moral actions are permissible. Is it permissible to take one human life in order to save others? We have powerful and surprisingly rich and subtle intuitions to such questions.In this class, you will learn how intuitions can be studied using formal analytical paradigms and behavioral experiments. Thursday evening, meet to learn about recent advances in theories of moral reasoning. Overnight,
