A self-made man and one of America’s greatest engineers, James Buchanan Eads led a life inextricably intertwined with the nation’s most important waterway, the Mississippi River. He explored the river bottom in a diving bell of his own design; made a fortune salvaging wrecks; in the 1870s built the world's first steel bridge over the Mississippi at St. Louis; then deepened the river at its mouth, turning New Orleans into the second largest port in the nation. By the time of his death in 1887, Eads was widely acknowledged to be one of the most influential men of his day.

Welcome to the Invisible Revolution, the story of Doug Engelbart, the man who invented much of the computer environment we live in today - and still few know his name. This is his story, and the story of his fellow dreamers, thinkers, doers - revolutionaries - who changed our lives forever.

The American Museum of the Moving Image is dedicated to educating the public about the art, history, technique, and technology of film, television, and digital media and to examining their impact on culture and society.

It achieves these goals by maintaining the nation's largest permanent collection of moving image artifacts and by offering exhibitions, film screenings, lectures, seminars, and other education programs.

Imagine that you're a poor person living during hard economic times. Your government offers you free medical care. Sounds good. But what if the real reason you're approached is because you have a disease. But instead of giving you medical care, the doctors are really just watching what happens when this disease goes untreated. Suppose a miracle then happens and a treatment is found for your disease. Instead of giving you the new medicine, the doctors continue the experiment of watching the disease go untreated. Years pass, some of your friends who were also in the study die, some pass the disease to their wives and children.

Utilizing over 800 scanned documents, photographs, audio clips and video excerpts, this website narrates the breathless details of the pursuit of the discovery of the double helix structure of DNA. Scattered throughout the project are images of a number of very important and extremely rare items, all of which are held within The Valley Library's Ava Helen and Linus Pauling Papers, and many of which have not been previously displayed. Also featured are two original documents hitherto unknown to scholars interested in this period. It is expected that this website will serve as a primary reference point for individuals interested in the history of DNA -- both researchers and lay people alike.

Media Interface Design- Powerpoint Presentation

Beginning in the 1960s, evolutionary biology was significantly transformed by the incorporation of ideas and techniques from molecular biology. This led to many novel views (and as many controversies) about phylogenetic relationships, rates and mechanisms of evolutionary change, and standards of inference and hypothesis testing.
This interactive website is devoted to recounting, documenting, and analyzing the history of molecular evolutionary biology. This is not just an activity for historians and philosophers. We especially encourage contributions and reactions from biologists.

The Society provides high quality forums for discussion of drug research among all disciplines, and on this occasion we have decided to make one of our symposia available (free!) to the scientific community worldwide by featuring our program online. Visitors to the Webcast will be able to hear each speaker's voice synchronised with the complete set of slides, graphics and photographs. Viewers can access the presentations by going to the Webcast page and clicking on the audio icon.

This site is all about a very special computer. It was called the baby, and
without it we would not have the computers we use today.

The purpose of Trinity Atomic Web Site is to tell the story of nuclear weapons through historical documents, photos, and videos. In the spirit of Project Gutenberg, the intent is to create an online archive from the large body of U.S. government information about nuclear weapons. For the most part the original documents will be allowed to speak for themselves, with an occasional thread of narrative or clarification if it is helpful.
