This collection shows photographs shows the construction of CP-1, or Chicago Pile Number One, that was done under the football stadium in an abandoned squash court at the University of Chicago. The pile contained 771,000 lbs. of graphite, 80,590 lbs. of uranium oxide and 12,400 lbs. of uranium metal when it went ?critical.? It cost about $1 million to produce and build. The pile took the form of a flattened ellipsoid, which measured 25 ft. wide and 20 ft. high.

This is a collection of issues of the magazine Scientific American, vols. 2-14 (1846-1859) and new series vols. 1-21 (1859-1869). During that period, Scientific American, the oldest continuously published magazine in the United States, provided reports of items submitted to the U.S. Patent Office and articles on the latest technology and research written for the general public. The collection, consisting of scanned images of pages, is browseable by year or searchable by keywords. The issues are part of Cornell University Library's contribution to the Making of America project, a digital library of primary sources in American social history (including history of science and technology) from the antebellum period through Reconstruction.

At the end of each summer, sea ice cover in the Arctic Ocean reaches its minimum extent and what is left is what is called the perennial ice cover (mainly thick multi-year ice floes). The area of perennial ice has been steadily decreasing since the satellite record began in 1979, at a rate of about 10 percent per decade. This visualization shows the annual minimum extent of sea ice in the Arctic Ocean from 1979 to 2007. A graph is overlaid that shows the area in millions of square kilometers for each year's minimum day. The previous record minimum (2005) and the new 2007 record minimum, far below the previous record and 38 percent lower than the climatological average, are highlighted. The visualization may be streamed from the website or downloaded in several formats.

ElectroSim 2.0 is a collection of theory-based interactive simulations of simple electronic circuits, suitable for a course in elementary practical instrumentation electronics; the simulations were created for use in an "Electronics for Chemists" course at the University of Maryland. Available for free download, the software can be used on Macintosh or Windows computers (a special utility is required to run it under Windows). Over twenty common analog circuits are included in the package. For each simulation, properties such as voltage, resistance, current, and capacitance can be changed to see how particular circuits behave under different operating conditions. There are easy to follow instructions and simple controls.

In 1905 a 26-year-old patent clerk named Albert Einstein published four exceedingly strange research papers-and gave us a whole new way to think about light, matter, energy, space and time. Indeed, his ideas about atoms, quanta and relativity laid the foundations for most of modern physics, not to mention microchips, lasers and a host of modern technologies. In 2005 the National Science Foundation celebrated the centennial of that miraculous year, an event known across the globe as the World Year of Physics. Explore what Einstein actually did in 1905-and all that has come of it since...
