Measuring & Mapping
Where, how far, and how much? People have invented an astonishing array of devices to answer seemingly simple questions like these. Measuring and mapping objects in the Museum's collections include the instruments of the famous—Thomas Jefferson's thermometer and a pocket compass used by Meriwether Lewis and William Clark on their expedition across the American West. A timing device was part of the pioneering motion studies of Eadweard Muybridge in the late 1800s. Time measurement is represented in clocks from simple sundials to precise chronometers for mapping, surveying, and finding longitude. Everyday objects tell part of the story, too, from tape measures and electrical meters to more than 300 scales to measure food and drink. Maps of many kinds fill out the collections, from railroad surveys to star charts.
"Measuring & Mapping - Overview" showing 1 items.
- Companies seeking to provide customers with advertisements they might consult repeatedly sometimes distributed convenient mathematical tables. This is an example of one of these. The small white plastic card has figures printed in blue. The table gives decimal equivalents of parts of an inch ranging from 1/64” to 1” by sixty-fourth inch increments.
- The other side of the card has a small drawing that shows the wooden building occupied by Brown & Sharpe Manufacturing Company of Providence, Rhode Island, in 1848. It also shows the plant at the time the table was distributed, when it occupied 33 acres.
- A mark on the back of the table reads: FORM 93 M.M.T. 7-43:100. Another mark reads: PRINTED IN U. S. A. This mark suggests that the card dates from 1943.
- This table was found in the collections of what was then the Division of Work and Industry at the National Museum of American History.
