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.

In 1974 Stanford University doctoral graduates Harry Garland and Roger Melen established a partnership named for their former dormitory Crothers Memorial Hall. Cromemco was formally incorporated in 1976.
Description
In 1974 Stanford University doctoral graduates Harry Garland and Roger Melen established a partnership named for their former dormitory Crothers Memorial Hall. Cromemco was formally incorporated in 1976. For the life of the company Garland and Melen remained the sole shareholders and avoided outside investment. At the insistence of their accountant, the company held a bank credit line but never had to tap the full amount. Their business philosophy was to grow only within the parameters of available cash. Revenues in 1975 were $50,000 and grew to an estimated $55 million by 1987 when the owners sold the company to Dynatech.
The company’s first products were a microcomputer system digital camera, the Cyclops, and a color graphics card called the Dazzler. From these products the company moved on to making reliable, high-quality business and scientific computers and in 1982, they introduced the C-10 Personal Computer. Cromemco systems were the first commercially marketed microcomputers certified by the U.S. Navy for use aboard ships and Ohio class submarines for data logging during tests. The United States Air Force became a major customer for their Theater Air Control System (TACS) and the Mission Support System (MSS) for F-16, F-15 and other aircraft. By 1986 more than 80 percent of the major-market television stations in the U.S. used Cromemco systems to produce news and weather graphics.
According to the user manual, “The C-10’s high-quality construction, continual self-testing, and proven design assure that it will perform faithfully year after year.”
This Cromemco C-10 microcomputer was used at Monroe High School in Monroe, MI from 1982-2008. In 1980 physics teacher Darol Straub started an after school computer class which led to the development of the school’s first formal computer curriculum. To be accepted into the course, students were required to take an aptitude entrance test. Classes were two periods per day for three years. Hardware and software topics included basic circuits to microcomputer design and building, and programming in binary code and assembly language as well as higher level languages such as BASIC, FORTRAN, PASCAL, COBOL, and “C.” The third year focused on developing advanced projects using speech recognition, numeric control, fiber optic communication, graphic design, and robotics.
Many of Straub’s students went on to college to study computer science and earned jobs with companies such as Microsoft and Intel. Two brothers who completed the curriculum opened a computer company when they graduated from high school. According to Mr. Straub, the company was still in business in 2018. The brother of the donor, also a student of Straub’s, graduated from Monroe High School in 2009 and MIT in 2013. He now works for Space X.
In 1988 the Computer Engineering Program students produced a 20 minute video “Monroe High School – Current Generation” which the school used to promote and recruit new students for the course.

This spectroscope was designed to be used with a telescope to study the light of the sun. It was made in Dublin in 1877 by the famous instrument maker Howard Grubb (1844–1931).
Description
This spectroscope was designed to be used with a telescope to study the light of the sun. It was made in Dublin in 1877 by the famous instrument maker Howard Grubb (1844–1931). It was used with the 9 ½ inch Alvan Clark & Sons refractor at Princeton University.
When the College of New Jersey at Princeton hired the astronomer Charles A. Young in 1877, they also gave him funds to equip the new John C. Green student observatory. One of his first purchases was this instrument. It was custom-made, and Young helped refine the design. (Grubb's company later advertised that this was the first such spectroscope that they had sold.) The most unusual feature of this instrument is the use of a complicated system of multiple prisms to disperse the light and produce a highly detailed view of the solar spectrum.
In use, the spectroscope was mounted at the eyepiece end of the telescope and light from the sun would be directed through it. As the light passed from one prism into the next, it would be increasing dispersed, or spread out. To make the instrument more compact, the beam of light was directed first through the upper portion of the prisms and then back through the bottom part. Depending on how it was configured, the light could thus be passed through either 2, 4, 6 or 8 prisms. A particular area of the solar spectrum could be viewed by turning a small chain that moved each prism by the same amount. Because of the large number of optical surfaces involved, the light loss in this instrument was almost certainly in the 90 percent range. This was an advantage when viewing the Sun, but it reduced the usefulness of this instrument for other purposes, such as measuring the spectra of stars. The success of this instrument in making precise measurements of the solar spectrum (and thus revealing information about the composition of the sun and its atmosphere) led to its wider adoption as an important astronomical tool.

From its infancy, timekeeping has depended on astronomy. The motion of celestial bodies relative to the rotating Earth provided the most precise measure of time until the mid-twentieth century, when quartz and atomic clocks proved more constant.
Description
From its infancy, timekeeping has depended on astronomy. The motion of celestial bodies relative to the rotating Earth provided the most precise measure of time until the mid-twentieth century, when quartz and atomic clocks proved more constant. Until that time, mechanical observatory clocks were set and continuously corrected to agree with astronomical observations.
The application of electricity to observatory timepieces in the late 1840s revolutionized the way American astronomers noted the exact movement of celestial events. U.S. Coast Survey teams devised a method to telegraph clock beats, both within an observatory and over long distances, and to record both the beats and the moment of observation simultaneously. British astronomers dubbed it the "American method of astronomical observation" and promptly adopted it themselves.
Transmitting clock beats by telegraph not only provided astronomers with a means of recording the exact moment of astronomical observations but also gave surveyors a means of determining longitude. Because the Earth rotates on its axis every twenty-four hours, longitude and time are equivalent (fifteen degrees of longitude equals one hour).
In 1849 William Cranch Bond, then director of the Harvard College Observatory, devised an important improvement for clocks employed in the "American method." He constructed several versions of break-circuit devices—electrical contracts and insulators attached to the mechanical clock movement—for telegraphing clock beats once a second. The Bond regulator shown in the forground incorporates such a device. Bond's son Richard designed the accompanying drum chronograph, an instrument that touched a pen to a paper-wrapped cylinder to record both the beats of the clock and the instant of a celestial event, signaled when an observer pressed a telegraph key.

Most nineteenth century American clocks were cheaply made for the mass market and domestic use.
Description
Most nineteenth century American clocks were cheaply made for the mass market and domestic use. But a few firms made finely finished precision clocks for applications where accuracy was vital: determining the time of scientific observations, for example, or regulating other clocks and watches. One such firm was E. Howard and Company of Boston, specialists in quality clocks, watches, and scales since 1842.
Howard's 1860 catalog featured this clock. It was advertised as an "astronomical clock" available in various styles, sizes, and prices, and recommended for observatories, watchmakers' shops, and railroad depots. Such a clock is today called a regulator, a particularly accurate timepiece designed exclusively for keeping time. Nonessential complications like striking mechanisms, calendar work, and moon dials are omitted. The case is likewise unadorned. This particular clock has a sixteen-inch silvered dial that indicates hours, minutes, and seconds separately. The steel pendulum rod carries two glass jars filled with mercury. The expansion and contraction of the mercury compensates for changes in the rod's length as the room temperature rises and falls.
About 1855, E. Howard and Company sold this clock to James Allan and Company, a Charleston, South Carolina, jewelry firm whose name is engraved on the dial. The regulator stood in the same Allan family store (called Charles Kerrison Company after 1960) from 1865 until it came to the Smithsonian in 1977, except for one brief period. On August 31, 1886, the regulator fell over when an earthquake rocked Charleston, and it briefly returned to the Howard factory for repairs.

Description
Arthur J. Weed was a skilled mechanic who, as chief instrument maker of the U.S. Weather Bureau, built and maintained the seismograph that Charles Marvin had designed in 1895. Moving in 1920 to the Rouss Physical Laboratory at the University of Virginia in Charlottesville, Weed gained access to resources that allowed him to go further in this field. With the aid of engineering students, Weed built a inverted pendulum seismograph with a 750-pound weight. Photographs of Weed with this massive instrument ran as an A.P. story in several newspapers. One headline read: “Trapping earthquakes has become a popular business at the University of Virginia, where one of the most unique and sensitive seismographs in the country keeps a twenty-four hour watch for tremors.”
Weed also designed a smaller inverted pendulum seismograph that could “be used in many places where a more elaborate installation is out of the question.” One account described a cylindrical steady mass of about six pounds resting on three wires placed in the form of an equilateral triangle to which an oil damping device is attached.” This is an instrument of that sort. It came to the Smithsonian in 1963.
When Weed died in 1936, the chief seismologist of the U.S. Coast and Geodetic Survey noted that “the science of seismology has lost one who has given much thought to instrumental problems, an active worker and a true friend.” The American Geophysical Union noted the loss of “a member who has long been active in the field of instrumental seismology.”

Description
A paper label on this seismograph reads “Made from the Designs of Professor Ewing of Dundee, by the California Electric Works, 35 Market street, San Francisco; and recommended for use in California by Professor LeConte of Berkeley and by Professor Holden, Director of the Lick Observatory.”
James Alfred Ewing was a young Scottish physicist/engineer who, while teaching in Tokyo in the years between 1878 and 1883, designed several seismographs. Among these was a duplex pendulum instrument that recorded the two horizontal components of earthquakes. It was, he claimed, “comparatively cheap and simple” and was “employed by many private observers in Japan.”
The Cambridge Scientific Instrument Company in England began manufacturing Ewing’s several seismographs in 1886. The first examples in the United States were installed in the Lick Observatory on Mount Hamilton and in the University of California at Berkeley. Edward Holden was then director of the former and president of the latter, and Joseph LeConte was professor of geology at Berkeley.
Enthusiastic about the new science of seismology, Holden and LeConte convinced Paul Seiler, head of an electrical apparatus supply firm in San Francisco, to manufacture duplex pendulum seismographs that would sell for $15 apiece (rather than the $75 charged by the English firm). Over a dozen examples are known to have been distributed across the country and around the world, some recording earthquakes as early as 1889. This one came to the Smithsonian in 1964, a gift of Case Institute of Technology in Cleveland, Ohio.
