Last year saw two interesting events in the world of double stars, both of them connected with an astronomer's old friend in the Big Dipper. While the early history of double star astronomy had to be completely rewritten after an examination of 17th century Italian manuscripts, its future at the beginning of the next millennium was briefly unveiled by the amazing precision of a new astrometric instrument, which will soon eliminate the difference between spectroscopic and visual binaries.

This website contains material useful to people studying the history of the CA/T highway, especially the Charles River crossing part of the project. During 1998, we operated an interactive website for the purpose of collecting original material from people who were involved in planning the crossing. Some comments and articles contributed by people involved in the crossing design process are available on-line. Other material at this website includes a chronology of planning the crossing, a chronological bibliography of important transportation documents with links to some of these, and images. Hardcopy material pertaining to the crossing is available in the vertical file collection at M.I.T.'s Rotch Library.

This was the first (but is not not the latest and greatest, for most purposes) online atlas of Mars. It lets you choose a site by various means and will show the locations (as footprints) of thousands of high-resolution Viking Orbiter images.

From around 3000 BC onwards, astronomy in its most primitive form had developed. The sun, moon and changing seasons would have already been well studied. Perhaps the chief difference in thinking at that time was that the earth was flat. People genuinely believed that if you went far enough you would fall off the edge.

Nearly 10'000 links to books on philosophy, science, classics, literature, history, economics, etc. Multilingual. Several Search programs on author, title, language, words, etc.

A brief overview of this Web site that compares what we knew in 1900 to what we know today

Repertorio di risorse Internet ad accesso libero, selezionate in base sia alla loro utilità per gli studiosi, sia alla loro affidabilità dal punto di vista informatico e degli aggiornamenti. Si tratta di siti creati da enti, editori e istituzioni autorevoli, che consentono il reperimento di informazioni di interesse generale da affiancare a quelle della collezione storica della biblioteca.

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.
