Science & Mathematics

The Museum's collections hold thousands of objects related to chemistry, biology, physics, astronomy, and other sciences. Instruments range from early American telescopes to lasers. Rare glassware and other artifacts from the laboratory of Joseph Priestley, the discoverer of oxygen, are among the scientific treasures here. A Gilbert chemistry set of about 1937 and other objects testify to the pleasures of amateur science. Artifacts also help illuminate the social and political history of biology and the roles of women and minorities in science.

The mathematics collection holds artifacts from slide rules and flash cards to code-breaking equipment. More than 1,000 models demonstrate some of the problems and principles of mathematics, and 80 abstract paintings by illustrator and cartoonist Crockett Johnson show his visual interpretations of mathematical theorems.

After their widespread use during World War One, experts increasingly used psychological tests as a tool to rank and sort people in contexts including (but not limited to) education and employment.
Description
After their widespread use during World War One, experts increasingly used psychological tests as a tool to rank and sort people in contexts including (but not limited to) education and employment. The Watson-Glaser Critical Thinking Appraisal (Form AM) was written by Goodwin Watson (Professor of Education, Teachers College, Columbia University) and Edward Maynard Glaser (Consulting Psychologist, Rohrer, Hibler, and Replogle, Los Angeles). It was published by the World Book Company and copyrighted in 1949 and 1952. According to the directions, the test aims to “find out how well you are able to reason analytically and logically.” To that end, the test contains questions about inference, recognition of assumptions, deduction, interpretation, and finally evaluation of arguments. The booklet is eight pages. For further context, see the Watson-Glaser Critical Thinking Appraisal Manual (1983.0168.21) and the Watson-Glaser Critical Thinking Appraisal Answer Sheet. (1983.0168.22)

The lower blade of this 24" brass hinged parallel rule is marked: KELVIN – WHITE CO. BOSTON – NEW YORK. The instrument has one rectangular wooden handle and one rectangular black plastic handle. Both handles are attached by crude welding.
Description
The lower blade of this 24" brass hinged parallel rule is marked: KELVIN – WHITE CO. BOSTON – NEW YORK. The instrument has one rectangular wooden handle and one rectangular black plastic handle. Both handles are attached by crude welding. They may have been added by the previous owner, since Kelvin & White catalog advertisements show round knobs in 1931 and no handles in 1940. The side and top edges of the rule are divided as a rectangular protractor, numbered by tens from 180 to 10 and from 360 to 180. Unlike MA.309661, MA.309662, and MA.309663, the bottom edge is not divided for a protractor or nautical compass points.
Australian shipbuilder Wilfrid O. White (1878–1955) studied in Glasgow, Scotland, with William Thomson, Lord Kelvin (1824–1907), before settling in Boston in 1902. White served as an agent for the Glasgow instrument workshop in which Kelvin Australian shipbuilder Wilfrid O. White (1878–1955) studied in Glasgow, Scotland, with William Thomson, Lord Kelvin (1824–1907), before settling in Boston in 1902. White started as an agent for a Glasgow instrument workshop which Kelvin had helped establish, sstaying there until about 1918 (after Kelvin's death). He then established the American firm of Kelvin & Wilfrid O. White.The company was renamed Wilfrid O. White & Sons, Inc., in 1950. Throughout its existence the firm charged $28.00 for the 24" brass version of "Captain Field's improved parallel rule," model number 554. The markings in this example are like those shown in the 1940 catalog.

This compact cylindrical handheld calculating machine has gray metal sides and a black top and operating handle. There are 11 slots along the side of the cylinder with plastic red and black levers that are pulled down to set numbers.
Description
This compact cylindrical handheld calculating machine has gray metal sides and a black top and operating handle. There are 11 slots along the side of the cylinder with plastic red and black levers that are pulled down to set numbers. The digit entered appears at the top of the slot. Multipliers are indicated by numbers read through holes around the edge of the top and may be up to eight digits large. The result also is indicated around the edge of the top, and may be up to 15 digits large. The top may be rotated, as one one would move a carriage on an earlier stepped drum machine. Sliding markers indicate decimal divisions for entries, multipliers, and results.
To zero the machine, the carriage is raised and the black disc under the operating lever is rotated through one turn using a clearing lever with a ring-like handle. The operating handle is pulled up for subtraction and division. Moving a lever on the side of the cylinder causes subtraction rather than addition in the revolution counting register. Operating instructions were received with the machine and are stored with it. The machine fits in a black metal cylindrical case. The lid of the case turns clockwise to open.
The machine and case are marked: CURTA, A mark on the bottom of the object reads: Type II (/) No 517304 (/) Made in Liechtenstein (/) (Customs Union with Switzerland) (/) by Contina Ltd Mauren (/) System Curt Herstark. The machine is marked on the lid: OPEN.
The Curta calculating machine was invented the Austrian Curt Hertzstark (1902–1988). He worked on the design during World War II as a prisoner at the Nazi concentration camp of Buchenwald, and produced the machine after the war in Liechtenstein. The Curta Type II was sold from at least 1954 until early 1972, when handheld electronic calculators replaced it.

According to the instructions received with the object, as long as one knows a TV station's published power and antenna height, this slide rule "quickly shows the approximate 'Grade A,' 'Grade B' and 'Principal City' Coverage for all VHF and UHF Television Stations.
Description
According to the instructions received with the object, as long as one knows a TV station's published power and antenna height, this slide rule "quickly shows the approximate 'Grade A,' 'Grade B' and 'Principal City' Coverage for all VHF and UHF Television Stations. In addition, it readily gives the approximate field strength in microvolts-per-meter for distances up to 100 miles from the television transmitter."
This one-sided wooden instrument is painted white on the front. A plastic indicator is in a metal frame. The top of the base is marked: EPPERSON TV COVERAGE CALCULATOR. It is also marked: COPYRIGHT 1952 (/) J. B. EPPERSON. The bottom right corner of the base is marked: ADLER COMMUNICATIONS LABORATORIES (/) NEW ROCHELLE, N.Y. The back of the rule has charts for converting decibels above one microvolt-per-meter to microvolts-per-meter and for identifying FCC required field intensities. Values from these charts are used in making calculations on the front of the rule.
Adler built numerous television and radio stations, including the first commercial UHF station, located in Portland, Ore. Founded by Benjamin Adler in 1947, the company changed names to Adler Electronics, Inc., in 1955 and remained in business at least through 1964. It probably distributed this rule as a promotional item. The rule was manufactured by Engineering Instruments of Peru, Ind., the successor firm to Lawrence Engineering Service. Compare to 1983.0042.01 and 1980.0097.02.
Joseph Bolen Epperson (1910–1995), the designer of this rule, studied at the University of Tennessee from 1927 to 1929 and with the Capitol Radio Engineering Institute (now Capitol College in Washington, D.C.) in 1932. After gaining experience as a chief engineer and supervisor of building and transmitter installation at radio stations in Knoxville, Tenn., and Huntsville, Ala., he joined Scripps-Howard Radio, Inc., of Cleveland, in 1937. He remained with the company until his retirement in the 1970s, leading the construction of several television stations and rising to vice-president for engineering in 1956. Pioneer and Headley-Reed also distributed his rule, sometimes called a "signal range calculator."

After their widespread use during World War One, experts increasingly used psychological tests as a tool to rank and sort people in contexts including (but not limited to) education and employment. The Sims SCI [Social Class Identifier] occupational rating scale was a single-sheet published by the World Book Company and copyrighted in 1952. This is the Scale of Form A. It lists forty-two different occupations and asks the test-taker to describe whether the people in the occupation “generally belong” in the same, a higher, or a lower social class as the test-taker and the test-taker’s family. For further context, see Sims SCI Occupational Rating Scale: Manual of Directions (1983.0168.28).

This full-keyboard,non-printing electric adding machine has a green metal frame and plastic keys in two shades of green.
Description
This full-keyboard,non-printing electric adding machine has a green metal frame and plastic keys in two shades of green. It was manufactured by the Bell Punch Company of London, England, for use with British currency.
The rightmost column has nine light green keys, with complementary digits indicated so that the digits on any key add up to 11. The next column from the right has nine dark green keys, with complementary digits indicated so that the digits on one key add up to nine. The next column has a single dark green key, with a one and complementary 0. There are then nine columns of keys, with nine keys in each column, and the usual complementary digits indicated. The leftmost column has six keys, numbered from 1 to 6.
Presumably the rightmost columns reads pence, the next two from the left shillings, and the next up to nine pounds. The leftmost column may be function keys. There are levers on either side of the keyboard. A row of 13 number dials is above the keyboard, and another row of 13 dials is below. The leftmost of these dials indicates a function, not a digit. The windows in the case over these dials are covered with glass. Below both registers is a row of knobs. The knobs are rotated to set decimal markers. A cord at the back of the machine has a wooden two-pronged plug. Taped to the plug are wires from a rubber-covered wire that has a two-pronged plug at the end.
The machine is marked on the front and the back: SUMLOCK. It is stamped on the bottom: GUARANTEED MADE IN GREAT BRITAIN. A metal tag on the bottom reads: DESIGNED AND MANUFACTURED (/) UNDER THEIR PATENTS BY (/) BELL PUNCH COMPANY LIMITED. (/) LONDON - ENGLAND. It also reads: U.S.A. (/) 2,142,286. . . 2,569,508. These are first and last U.S. patent numbers in a list of U.K., Australian, Swiss, Swedish, Belgian, Canadian, U.S., French, and Danish patents. A small piece of tape once attached to the side of the instrument reads: #11 SUMLOCK FRAC. (/) CAL. (/) #500078. Last number of this mark may be serial number of instrument. A red Burroughs Patent Department tag reads: PATENT DEPT. (/) #312.
