This is a page by David Waite that explains relativity theory at an advanced level. It is focused on special relativity. It warns that the reader must have a good understanding of algebra and calculus. It provides a link to a general relativity page from the same author.
Air Safety: Nothing But Blue Skies?
While Arnold Barnett acknowledges addressing the same questions around flying year after year (“Does he ever change his schtick?”), he advertises some new twists this time ‘round. Barnett remains remarkably consistent, though, in his quite sunny assessment of the current state of aviation safety -- even after a recent
Composing a Career and Life
Linda Mason was originally going to make a case study of Bright Horizons, her $1.3 billion, early childhood care business, but reconsidered in light of the current economic crisis -- to the benefit of her audience. Instead, she takes up her own story as a recession-era entrepreneur who built several hugely successful, social
Transitioning from the Space Shuttle to the Constellation System
William Gerstenmaier knows the U.S. space program inside out -- both literally and figuratively. As a 30-plus year veteran of NASA, Gerstenmaier has managed the operational dimensions of the space shuttle, international space station, and other space flight missions. For this AeroAstro talk, he dissects a problem that
A New Age of Exploration: From Earth to Mars
Happily for human spaceflight, Dava Newman and her students enjoy working in such laboratories as NASA’s “Vomit Comet.” Newman’s work aims to provide a better understanding of how humans can withstand the rigors of space missions. Her decades studying human physiology and performance in extreme environments may pro
Battle of Gettysburg: change the plan or persist?
The Battle of Gettysburg offers timeless lessons to Soldiers, military leaders, corporate CEOs and others. Listen to Professor Len Fullenkamp, Army War College historian, discusses when to change the battle plan and when to persist.
From molecules to physiology, PLoS Pathogens publishes important new ideas on bacteria, fungi, parasites, prions, and viruses that contribute to our understanding of the biology of pathogens and pathogen-host interactions.
Tropical Ecology and Conservation
This seminar plus field work in Costa Rica is designed to give students with an in-depth understanding of tropical ecology and conservation biology. More specifically it provides students the opportunity to (1) read the original literature, (2) give oral presentations, (3) design and write a research proposal, and (4) gain hands-on research experience in Costa Rica. Here are what the students say are the highlights of the course: 1. Learning how to write a proposal and executing that project. 2.
This course examines contemporary theory and research on the development of intellectual processes from infancy through adolescence. It compares cognitive-developmental theories and research to psychometric,information-processing, and other approaches. The final project, the metahobby project, fosters the student's ability to think theoretically and apply good theory in professional and personal ways.
Mesoscopic physics is the area of Solid State physics that covers the transition regime between macroscopic objects and the microscopic, atomic world.The main goal of the course is to introduce the physical concepts underlying the phenomena in this field. Study Goals: Reach understanding of electronic properties of meso-size conductors, appreciate/recognize the role of classical and quantum processes, being able to explain electronic transport phenomena using simple physical concepts.Author(s):
Banco Itaaú BBA's Candido Bracher: 'The Party Will Not Be as Fancy as Before'
Economic crises around the globe have often hit Brazilian banks hard, with capital flight hammering the country's currency, the real. But Brazil's financial institutions seem better positioned to weather the current worldwide credit crunch, although lending there is just as frozen as it is elsewhere, according to Candido Bracher, president and chief executive officer of the São Paulo-based Banco Itaú BBA, one of the country's largest private banks. In an interview with Knowledge@Wharton, Brach
Leamer on Macroeconomic Patterns and Stories
Ed Leamer, of UCLA and author of Macroeconomic Patterns and Stories, talks with EconTalk host Russ Roberts about how we should use patterns in macroeconomic data and stories about those patterns to improve our understanding of the economy. Leamer argues that economics is not a science, but rather a way of thinking, and that economic models are neither true nor false, but either useful or not useful. He discusses various patterns in the recessions and recoveries in the United States since 1950. T
A Gentle Introduction to Nanotechnology and Nanoscience
While the Greek root nano just means dwarf, the nanoscale has become a giant focus of contemporary science and technology. We will examine the fundamental issues underlying the excitement involved in nanoscale research - what, why and how. Specific topics include assembly, properties, applications and societal issues.
Interview with Marcus Amerman (Choctaw)
Jennifer Complo McNutt, curator of contemporary art, interviews Marcus Amerman (Choctaw) who reveals how he creates his revolutionary beaded works. He also talks about the signature piece he is creating for the 14th Annual Eiteljorg Museum Indian Market.
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
Extraterrestrial impact in Yucatán, lava floods & Cretaceous-Tertiary extinction
Extraterrestrial impact in Yucatán, lava floods in India, and the great Cretaceous-Tertiary extinction: A New Autopsy Report on T. rex and Friends Mark Richards, Executive Dean of Letters & Science, Dean of Mathematical & Physical Sciences, and Professor of Earth & Planetary Science, presents his latest research on the extraordinary events surrounding the disappearance of dinosaurs, first introduced at Berkeley as the famous ""Alvarez hypothesis."" This lecture was given at an event recognizin
Water: A Source of Life and Culture
asks students to research and analyze the role of water in daily life and create symbols to represent their findings. The students' symbols are then arranged to create a contemporary work of art.
The Essence of a Mask, #12 (enhanced) Masks of Mexico Audio Tour (end)
For those interested in collecting masks there are many elements to consider. Masks in Mexico are created for different reasons: as folk art, as components of religious ceremonies or traditional celebrations, as talismans... The story behind the mask may be the most valuable thing about it. ASM store manager Martin Kim shares his knowledge and understanding of collecting traditional art forms.
