12.581 Phase Transitions in the Earth's Interior (MIT)
This course discusses phase transitions in Earth's interior. Phase transitions in Earth materials at high pressures and temperatures cause the seismic discontinuities and affect the convections in the Earth's interior. On the other hand, they enable us to constrain temperature and chemical compositions in the Earth's interior. However, among many known phase transitions in mineral physics, only a few have been investigated in seismology and geodynamics. This course reviews important papers about
SAGP Guide to Clinical Medical Practice
Manual originating from personal notes made over many years of semi-rural private and hospital practice in South Africa. A useful resource based on many years of semi-rural private and hospital practice in South Africa involving major trauma, surgery and obstetrics, in addition to the common problems of general practice. I have always felt it very useful to be able to confirm facts and figures at the bedside if needed and this has been the motivation that has taken me over 40 years. This meant
Letters from the Frontier: Reading and Writing Primary Documents
By immersing themselves in primary sources (George Catlin's letters), students will learn the difference between objective and subjective writing styles. They will draw facts out of the letters to create newspaper articles in Activity 1, and write their own letters as if they were members of the Catlin family in Activity 2. These activities are designed to enliven historical figures, to connect the "current events" of the past with the current events of the present, and to help students read and
The Spanish-American War in Motion Pictures
This site features films and actualities taped in the U.S., Cuba, and Philippines showing troops, ships, notable figures, and parades, as well as reenactments of battles and other wartime events. These films mark the first U.S. war in which the motion picture camera played a role.
Baseball Cards, 1887-1914
This site presents 2,100 early baseball cards. The cards show such legendary figures as Ty Cobb stealing third base, Tris Speaker batting, and pitcher Cy Young formally posing. Other notable players include Connie Mack, Walter Johnson, King Kelly, and Christy Mathematics and Statisticsewson.
WWII: The War Economy - US History: from Civil War to Present
What does it mean to be an American? Far from being a fixed concept, over the past 150 years American identity has been constructed and reconstructed through the conflicts, interchanges, and negotiations between different ethnic, cultural, and religious groups. In this course, we will pay particular attention to two major transformations in American identity: the shift from a conception of citizenship grounded on race to one grounded on shared democratic ideals; and the development of the United
Biological Soil Crusts
This USGS Canyonlands Research Station site features a series of web pages focusing on biological soil crusts. Biological soil crusts are the community of organisms living at the surface of desert soils. The site provides a menu of links to biological soil crust pages including Crusts 101: an introduction to biological soil crusts, an advanced page with a downloadable 90-page report on soil crusts, a gallery of biological soil crust images and figures, references, the Canyon Country Ecosystems R
Significant Figures Tutorial
In many of the problems in these tutorials, you will be asked to report your answer with a specific number of significant figures. This section provides a brief review of the topic. For a thorough review of significant figures, please see this web site. Here are some examples of how to count significant figures.
Earning 100 Snelfus
In this Cyberchase video segment, the CyberSquad figures out how to earn 100 snelfus in 11 days.
Film Shoot: Day 4
In this Cyberchase video segment, the CyberSquad figures out how to incorporate a new scene into their film while staying within their budget.
Look inside a battery to see how it works. Select the battery voltage and little stick figures move charges from one end of the battery to the other. A voltmeter tells you the resulting battery voltage.
Self Driven Particle Model
Learn how simple rule-driven dynamical systems can produce complex dynamical behavior, like 2nd order phase transitions, criticality and clustering. This simulation will guide you through a tutorial that introduces the model incrementally and depicts the computation of the order parameter, critical ...
We'd Like to Thank You, Herbert Hoover
Since the advent of book musicals such as "Show Boat" and "Oklahoma!", many Broadway shows have touched upon relevant social and historical issues. In this lesson, students will investigate how Broadway musicals can reflect the times in which they were created. Students will examine video clips and Web sites related to relevant productions, study song lyrics, and compare and contrast actual history with Broadway history. By becoming "historical detectives," they will determine how accurately Bro
Demonstration on How All Angles in a Triangle Add up to 180
This video demonstrate how all angles sum to 180 degrees. A student made skit is presented on a whiteboard with magnet figures of Paris Hilton and Einstein to demonstrate.
Finding Area of Complex Figures
The instructor demonstrates how to find the area of complex figures consisting of one or more rectangles. They show how to break the figure up into two different figures and then add the areas together. The first figure is in the perimeter video, so to find the missing sides you could watch that video or just go on in this video and they give you the measurements. They discuss the formula for area of a square and rectangle and use this to find the area of the two figures and then add

This program that explores the work of of famous American Authors in history. In the years just before the Civil War major literary figures Poe and Hawthorne are explored along with their literary works in this clip.
Ms. Meyer teaches about the associative property. She models an example of association with character figures. Next, she uses mathematical examples to answer these questions: What is the associative property? Why does it have the name it does? How can you recognize it when you see it?

William Jennings Bryan's Cross of Gold Speech
By the early 1890s, the Populist Party and figures within the
Democratic and Republican Parties advocated "free silver" (a
silver-standard currency at a high price for silver that would bring
inflation). The Populists represented an alliance of rural interests
and silver mining interests. Free silver advocate William Jennings
Bryan became the Democratic presidential candidate of 1896, delivering
the famous "Cross of Gold" speech denouncing the gold sta
