This document is the response of the Harvard University Physics Department to a proposed Congressional amendment in 1950 requiring that the FBI investigate scientists’ “loyalty” before they could receive government contracts. As the Harvard scientists write, heavy-handed attempts to root out the very rare disloyal applicant would be highly damaging overall to the morale of researchers.
This document from 1948 expresses concern by members of the National Academy of Sciences (NAS) over the political persecution of Edward Condon, a physicist and director of the Bureau of Standards. Dating back to the 1860s, the NAS is a professional association tasked with giving scientific advice to the government.
This document from 1948 circulates to members of the American Academy of Arts and Sciences (AAAS) the organization’s position on the political persecution of Edward Condon, a physicist and director of the Bureau of Standards. Condon was a moderate internationalist who had a then-mainstream view that atomic bombs were too dangerous for any one country to control.
Many people in West Africa fled across colonial boundaries to avoid military conscription in the late 19th and early 20th century. For example, during World War I, tens of thousands of people left the French colony of Senegal for neighboring British Gambia and Portuguese Guinea-Bissau.

These maps show two constructed least cost pathways between Flinty Bay on Long Island just off the coast of Antigua (the right end of the line) and Jolly Beach on Antigua (the left end of the line).

Brochure for the South Carolina Inter-State and West Indian Exposition / Charleston Exposition, 1901-1902
This is the cover for a pamphlet to promote the Charleston Exposition and recruit exhibitors and attendees from along the entire U.S. Atlantic, which ran from New England to Florida to Cuba and Puerto Rico. It is an effective visual representation of how cotton growers and textile and apparel producers envisioned the U.S.
These side by side charts show the basics of how least cost pathway analysis works in action. A geographic surface, landscape or seascape, is broken into standard size squares (or cells). These cells are then given a value based on an underlying factor in the geographic area, such as the slope of a hill calculated into a cost to climb up it, or the force and direction of a sea current.
This image showcases one of the few remains of a canoe found in the Caribbean. The ‘Stargate’ canoe, found in a blue hole—a large marine cavern--on the island of South San Andros in the Bahamas, represents only the tip of the canoe.
