Science & Mathematics

Chemical Balance

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.

Educational Software for Use with the Commodore 64 Microcomputer, Typing Professor

This group of five educational computer programs was developed for the Commodore 64 during the 1980s.
Description
This group of five educational computer programs was developed for the Commodore 64 during the 1980s. Each program has its original box, the 5 ¼” software diskettes, and the user manual.
Word Shuttle
This word processing program was released in 1985 and included a 42-page user guide and two keyboard overlays. Word Shuttle was the official word processor of the Young Astronaut Program which operated between 1984 and 2004. The objective of this international educational curriculum was to promote greater interest in science, technology, engineering and mathematics (STEM) through space-themed activities, experiments, and conferences.
Sky Travel
This astronomy program, designed for persons ages 12 and up, was released in 1984 and included a 138-page manual. It provided an interactive guided tour of the universe—in the past, present, and future. The universe model could show the location of more than 1,200 stars, 88 constellations, 8 planets, deep sky objects, and the (then) future appearance (1986) of Halley’s comet. The program had four basic modes: map, set, sky, and chart. Map was used to select the location on Earth; month, day, year, and time were determined in set; optional displays were chosen in sky; and chart was used to project the sky on a celestial sphere with coordinate lines for creating, viewing, and printing your own star charts.
JUST IMAGINE…
This creative writing program, released in 1984 for individuals of all ages, included a 20-page manual. The user could create colorful animated stories by selecting up to three animated characters from the twenty-five provided, choosing one of nine backgrounds, and a few of the 48 stationary objects. The author then wrote a story to match the selected graphics. While different parts of the program loaded it displayed random trivia facts from the 300 stored on the diskette. The story could be played back and saved to diskette. The introduction in the manual states that “JUST IMAGINE… is another example of Commodore’s commitment to excellence-in-education through technology.”
Reading Professor
This reading program, released in 1984, was designed to teach reading skills to high school-age students as well as adults. Included with the two software diskettes was a 40-page user guide. The program provided a series of ten 20-minute lessons to increase reading speed and improve comprehension by presenting specific techniques for eliminating bad reading habits and developing new skills. It has a library of reading materials with three reading levels--High School, College and Adult, and Professional. Each level contains thirty-two reading selections. The program used seven types of exercises to monitor and log progress and success.
Typing Professor
This typing program, released in 1984 for individuals ages 12 and up, included a 20-page manual, two cassettes for use with a Commodore 16, and a diskette for use with either a Commodore 64 or Commodore Plus/4.
Students could learn the basics of touch typing or learn to improve their typing speed. The program had 19 exercises which increased in difficulty. Each exercise contained a score chart that calculated and recorded the number of errors, error rate, and typing speed. The exercises were timed and the student could not exceed the acceptable error rate before beginning the next exercise. The allowed error rate started at 4% for lesson 1 and decreased to 1% for lessons 16-19. The goal for lesson 19 was 35 words per minute with a less than 1% error rate.

Cromemco C-10 Microcomputer

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.

Description (Brief)
William Dougal (1822–1895) of Washington, D.C. engraved this print of “Phrynosoma regale [Girard] and Doliosaurus m’callii [Girard]”—now "Phrynosoma solare" (Regal horned lizard) and "Phrynosoma mcallii" (Flat–tail horned lizard); from one or more original illustrations by John H. Richard (c.1807–1881) of Philadelphia. The illustration was published as Plate 28 in the “Reptiles” section of the second part of volume II of the Report on the United States and Mexican Boundary Survey, written by S.F. Baird (1823–1887). The volume was printed in 1859 by Cornelius Wendell of Washington, D.C.

Astronomical Spectroscope

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.

Chronograph

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.

Binocular Telescope

Ever since the invention of the telescope around 1600, many opticians have considered the advantages of binocular telescopes, and some actually produced instruments of this sort. The form, however, did not become widely available until the latter decades of the19th century.
Description
Ever since the invention of the telescope around 1600, many opticians have considered the advantages of binocular telescopes, and some actually produced instruments of this sort. The form, however, did not become widely available until the latter decades of the19th century. This example is an aluminum instrument with aluminum sunshades. The objective lenses are about 1.6 inches diameter; the length overall, when closed, is about 11 inches. One eyepiece barrel is marked “T. W. Watson / Optician” and the other is marked “4 Pall Mall / London.” The cross frame has two knobs, one for focusing and one for adjusting the inter-ocular distance. The barrels are covered with black leather. The case is brown leather.
T. W. Watson (fl. 1868 to 1884) sold guns and optical instruments.

Inverted Pendulum Seismograph

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.
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.”
