Launch of HMS Albion at Blackwall (1898)
E.P. Prestwich's footage of the launch of the battleship HMS Albion on 21 June 1898 looks deceptively serene and gentle. What it doesn't show is that when the ship hit the water for the first time, it created a wave that swept away a jetty, drowning an estimated 39 people in the process, one of the worst peacetime disasters in the Thames's history. The film is included in the new BFI DVD 'Tales from the Shipyard', featuring over five hours of documentary film revealing the history of British
MIDWAY JOURNEY - Plastic Beach Pollution
In the Greek mythology, Sisyphus was a king who was cursed to roll a
huge boulder up a hill, only to watch it roll back down, and to repeat
this throughout eternity.
A beach cleanup on Midway Atoll made us feel just like Sisyphus.

constantly fragmenting into smaller and smaller pieces which are
scattered throughout the water column and present, in different
Congressman resigns over web scandal
Married Republican congressman resigns after sending flirty emails and photos to a woman he met on the Internet. Deborah Gembara reports.
Developing modelling skills
This unit is the third in the MSXR209 series of five units on mathematical modellng. It provides an overview of the processes involved in developing models, starting by explaining how to specify the purpose of the model. It then moves on to look at aspects involved in creating models, such as simplifying problems, choosing variables and parameters, formulating relationships and finding solutions. You will also look at interpreting results and evaluating models. This unit assumes that you have pr

This was also the first time that a child was used in a campaign ad. (1:00)
Math in Society
Math in Society is a free, open textbook. This book is a survey of mathematical topics, most non-algebraic, appropriate for a college-level topics course for liberal arts majors. The text is designed so that most chapters are independent, allowing the instructor to choose a selection of topics to be covered. Emphasis is placed on the applicability of the mathematics. Material for each topic is covered in the main text, with additional depth available through exploration exercises appropriate for
Data Tool Program
Data Tool is a data analysis tool for plotting and fitting data from laboratory experiments, simulations, video analysis, or any other data set organized into columns. A click of a checkbox in Data Tool allows the user to change the appearance of plots, see standard statistics for the data set or apply built-in linear, quadratic or cubic fits to the data set. Data Tool also includes a number of standard mathematical functions that can be applied to the data set, allowing for further analysis and
Introduction to Nanoscale Science: Surface Area to Volume Ratio Module
Many intriguing phenomena observed in the "nanoworld" can be attributed to the increase in the surface to volume ratio ( SVR ) at the nanoscale. Understanding the surface area effects to volume changes is thus crucial to the understanding of nanoscale phenomena and nanotechnology applications. As an introduction to the nanoworld, the major goals of this module are to (1) give students a feel for just how small the nanoscale is, (2) give students practice in mathematically communicating nanoscale
Algebraic thinking: a basic skill
The resources highlighted here aim to reflect students' growing mathematical capacity over the span of the middle school years. The activities and lessons, intended as supplementary materials, range from introduction to the fundamentals of algebra to work on linear functions. Uniformly, they take into consideration the preference of the middle school student for concrete models, visual representations, and interactive tasks.
Social Capital and the Distribution of Household Income in the United States: 1980, 1990, and 2000
Social capital is a person or group's sympathy or sense of obligation for another person or group. The objects of sympathetic feelings have social capital. Those holding sympathetic feelings for others provide social capital. Because social capital providers internalize the consequences of their choices, they trade with each other on different terms and at different levels that would occur in arm's length transactions, all other things equal. But changes in the terms and level of trade al
Active Participation: Using Math Templates
Using math templates during instruction keeps each student actively involved and allows the teacher to informally assess each student's proficiency with the skills and concepts addressed in the day's lesson. Many teachers regularly use whiteboards to have students record answers, write terms, draw pictures, etc. The use of templates in sheet protectors extends this practice and eliminates the time spent drawing diagrams, etc., allowing students more time to demonstrate mathematical proficiency.
Math Activities for Fall (2007)
These activities were designed to introduce or reinforce important math concepts and skills using seasonal themes. This is a natural fit for elementary classrooms where teachers and students celebrate the various holidays with literature and art projects. These activities allow teachers to also incorporate math activities that develop and support important mathematical concepts and skills.
Gingerbread Man Math
Gingerbread men and gingerbread houses enjoy special popularity around the holidays, but many of these gingerbread activities are timeless and complement literature titles that teachers use at the beginning of school or after the holidays. It's very easy to incorporate mathematics into a study of gingerbread men, and students will enjoy the data collection activities and games while learning math skills and deepening their understanding of important mathematical concepts. Look through these math
