Scientific/Historical Traveling

A website designed to gather and organize information related to scientific/historical traveling.

It was developed in connection with the 2002 Allegheny College ACCEL Study Tour entitled

 Traveling with the Atom: London and Paris
Click Here for Description, Itinerary, Participants, and Pictures

and the Alumni College 2002 course entitled

 Alumni College 2002: Traveling with the Atom
Class Titles and Reading Assignments


A major reference for both of these groups was the book Uncle Tungsten: Memories of a Chemical Boyhood
Oliver Sacks, Alfred A. Knopf, 2001. 
(Click on the image for ordering information.)
(Click here for a summary of the book pertaining to history of chemistry topics.)
 

The website is organized by personalities seminal to the development of the atomic concept.
These are presented below in approximately chronological order.
