Aztecs: Inside the hidden empire 3/5
The Pyramids are described and they explain what they were used for: they were open places used like theatres. There are images of sculptures representing Gods. The images of the Gods reflect their way of life. Blood was given to the Gods in rituals. The temple of warriors is described and what analysis of the place has shown. The most common sacrifice and ceremonies are refered to. There is a map showing how big the Empire grew. There is an explanation of how society was organised and of the re
Simple Analysis of Cost Per Job Saved from Stimulus
A simple analysis of cost per job saved from stimulus in this clip. The calculations to determine cost per job saved are shown on the screen as the narrator calculates with a calculator.
The Story of Cap & Trade
The Story of Cap & Trade is a fast-paced, fact-filled look at the leading climate solution being discussed at Copenhagen and on Capitol Hill. Host Annie Leonard introduces the energy traders and Wall Street financiers at the heart of this scheme and reveals the "devils in the details" in current cap and trade proposals: free permits to big polluters, fake offsets and distraction from what’s really required to tackle the climate crisis. (This is a professional video that is strongly against
BBC Nature: Mega Tsunami - Evidence of Destruction
Scientists uncover evidence of disastrous damage to the coastline at Lituya Bay. Analysis of tree rings from the tree trim line show evidence of an impossibly high wave - a Mega Tsunami.
Cupcake Economics 2
This is Part 2 continuing on the cupcake factory business analysis. This part shows how to fill out the spreadsheet with the investment figures.
Language and Speech: Broca's and Wernicke's Areas
The left hemisphere is dominant in this module on language and the brain. Relationships between specific brain areas and verbal processing are shown through the historic example of Dr. Paul Broca’s brain-injury patient. The patient’s preserved brain is subjected to CAT scan analysis, which shows correspondence between the damaged area and the patient’s documented d
Can We Believe Our Eyes
Why is it that students can graduate from MIT and Harvard, yet not know how to solve a simple third-grade problem in science: lighting a light bulb with a battery and wire? Beginning with this startling fact, this program systematically explores many of the assumptions that we hold about learning to show that education is based on a series of myths. Through the example o
Workshop 6: Force Against Force
Magnets stick to other magnets and to metal objects made of iron or steel. How much force is required to break the attraction between two magnets? In this workshop, fourth-grade students explore ways to balance the force of magnetism against the force of gravity. A magnet placed in a cup on one side of a pan-balance is stuck to a stationary magnet beneath the cup. When e

The global food crisis: How can we free the hungry billions?
The international community is facing the most pressing humanitarian and development challenges in global history which include the fate of an estimated one billion people who exist on less than $1.25 per day. Such challenges require all development actors to embrace a spirit of innovation and renewal and to think again about their approaches to human development. There is widespread support for overseas development assistance amongst the Australian public with some recent surveys suggesting tha

The science of climate change structures the economics: risk of major damage and a global response must be at the core of an analysis of policy. History and wealth structure the ethics. The economics of climate change must, therefore, point to effective, efficient, and ethical, as well as collaborative, policy responses. This lecture will follow this analysis and describe a possible global deal or framework and how it might be built.

John Haldon, Princeton University: History, Remote Sensing, and GIS - The Avkat Survey Project
This talk introduces briefly the Avkat Archaeological Survey, a collaborative research project in north-central Anatolia which seeks to integrate a number of different approaches to studying the past, using recent technological advances to integrate disparate datasets into a cohesive framework of analysis. From the 1980s, there has been continued development of methodologies of archaeological field survey, as well as remote sensing techniques ranging from ground-penetrating radar to airborne rad

Sam Wang: The Princeton Election Consortium - A First Draft of Electoral History - February 11, 2009
Lunch 'n Learn presentation: How we experience political races is dominated by opinion polls. Polling data can be confusing because of their sheer number. In 2008, hundreds of polls were released during the Presidential campaign. Is there a way to cut through the resulting noise?
Four years ago Dr. Wang devised a statistical approach to analyze state polls to get a single, easy-to-understand snapshot of the race, viewed from the point of view of the Electoral College. In 2008, this approach mad

Andrea LaPaugh: Foundations and Future of Information Search - March 4, 2009
Lunch 'n Learn presentation: Everyone googles - in the U.S, about 12 billion times a month (including search engines that aren’t Google). We are mostly pleased with the results we get. How can it be that we give an automated system a couple of words and it finds reasonably relevant documents among one hundred billion or so possibilities? Will our satisfaction with these tools increase or decrease as the Web and our expectations grow?
Dr. LaPaugh gives a peek “under the hood” and discuss

The Fruits of the Genome for Society - February 17, 2010
Lunch 'n Learn presentation: The sequence of the human genome, the primary goal of the Human Genome Project, was achieved just a few years ago. Because our genomes are a string of 3 billion sequences of four chemical letters in the DNA polymer, the ability to obtain genomic sequences depended on revolutionary progress not just in DNA chemistry but also on the equally revolutionary advances in speed, capacity and versatility of digital computers. By far the most prominent result of the determinat
