Compressive and tensile deformation in bubble raft
Bubble raft undergoing compressive and tensile deformation. At small strains, the arrangement of the bubbles does not change. This is elastic deformation of the raft. The bubbles change shape and move slightly apart in an effort to maintain the lowest energy close-packed configuration. At larger strains, plastic deformation occurs. The bubble raft rearranges by dislocation motion. From TLP: Introduction to dislocations, http://www.msm.cam.ac.uk/doitpoms/tlplib/dislocations/dislocation_motion.php

9.52-C Computational Cognitive Science (MIT)
An introduction to computational theories of human cognition. Emphasizes questions of inductive learning and inference, and the representation of knowledge. Project required for graduate credit. This class is suitable for intermediate to advanced undergraduates or graduate students specializing in cognitive science, artificial intelligence, and related fields.
TALAT Lecture 3206: The Feeding of Castings
This lecture provides an introduction to the techniques used to compensate for the solidification shrinkage of castings. The students will be able to understand the basic principles of how to design a feeder system to produce a shrinkage-free casting. Basic knowledge of castings production, basic physics and metallurgy background is assumed.
8.09 Classical Mechanics (MIT)
This class provides a formal introduction to classical mechanics, Euler-Lagrange equations, Hamilton's equations of motion used to describe central force motion, scattering, perturbation theory and Noether's theorem. The course also extends to continuous and relativistic systems and classical electrodynamics.
The Embryo Takes Shape
Genes direct the development of a growing embryo. But not all genes in a cell are active at any given time. Sometimes a cell's location in the developing embryo determines which genes get turned on and which genes stay inactive. This video segment from NOVA: "Life's Greatest Miracle" explores the developmental process of an embryo beginning just two weeks after fertilization. Closed captioning included. Run time 07:47.
Capturing design context in distributed communication of software engineers
Software engineering is a knowledge-intensive activity. It requires developers be aware of changing requirements, involvement of others, and the overall status of the project. Code, as the embodiment of developersâ intent, does not represent all knowledge required to work on the project successfully. Even in projects with the best software process practices, where requirement and design documents, bug databases, and source control software are kept up-to-date, most knowledge is still containe
Gravity Overview - Free Science Video by Brightstorm
All objects with mass attract and are attracted by all other objects with mass because of a force called gravity. The strength of gravity is proportional to the mass of the object. We are pulled to the Earth by it's gravitational forces but we also pull the earth towards us. Because we are much less massive than than the Earth, our gravitational pull is not strong enough to have any affect on it. Gravity pulls us towards Earth such that we accelerate at 9.8 m/s^2. &n
Polar Bear Moving Over Thin Ice and Swimming Between Ice Floes
This short video gives excellent real life footage of a large polar bear in its natural habitat walking and moving over thin ice and swimming between and under large ice chunks. Students will get a close up view of the polar bear swimming under water. This is a great resource to help build background knowledge and to help make real world connections between nature and the classroom. (Less Than 2 Minutes)
Assessing your skills
Welcome to Assessing Your Skills one of the series of Futures workbooks, which help students choose and prepare for their careers. Like the other workbooks in the series you can dip in and out doing the exercises which are most relevant to you. You might want to include the exercises or the output in your personal development plan or e-portfolio. The aim of this workbook is to help you to clarify or identify your skills as a first step toward choosing work that really suits you. It can also he

h-BN inclusion in a β-Si3N4 grain
The micrograph shows h-BN inclusion (precipitate) in a β-Si3N4 grain (within a silicon nitride particulate-reinforced silicon carbide composite). The occurrence of BN inclusions results from the introduction of colloidal BN into the hot isostatic pressing process. They are formed from B2O3 present as a thin surface film on the BN particles in the barrier layer. B2O3 will be molten during the pressing process and will diffuse rapidly into the powder compact and react with Si3N4 to form BN. Such
