This program is the first public showing of a film (whose title is from a line in Keats's "Ode on a Grecian Urn") made by Donald H. Andrews and funded by Mrs. William Hale Harkness. Dr. Andrews hypothesizes that all matter is music since all matter in the universe vibrates, and tones and harmonies are made by vibrations. The motion of a plucked violin string and its adjacent string (sympathetic resonance) are shown in slow motion and on an oscilloscope. Dr. Andrews discusses one dimensional harmony, as described by Pythagoras. Two dimensional harmonies are indicated by the fractional overtones of a drum head membrane, which is shown in slow motion and heard electronically enhanced. Three dimensional harmonies result from the contraction and expansion of a sphere; however, differently shaped solids, such as statues, have fractional resonances that produce unique chords or harmonic patterns when vibrating. Four dimensional harmonies come from atom vibration, a wave whose harmonic pattern is displayed by a vibrating sphere. Thus, Dr. Andrews concludes that since an atom is not a particle that vibrates in space, but rather the vibration itself, all matter is in dynamic form or all matter is music. He continues by playing on a piano the chords of tones of atoms produced by different chemical compounds. He also shows and discusses the pattern of Bach's music on an oscilloscope and music composed by Rebekah West Harkness. In conclusion, Dr. Andrews discusses the dynamic form of the human body's symphony and its small chords in the larger universe
High anxiety ( Visual )
1 edition published in 1996 in English and held by 2 WorldCat member libraries worldwide
A twenty year old man died after using the over-the-counter herbal drug Ultimate X-phoria, which is made with a Chinese herb called Ma huang. Dr. Nancy Snyderman reports that it is a form of ephedrine, which is found in much higher doses in herbal drugs that are not regulated by the FDA because they are considered food supplements
Asian flu ( Visual )
2 editions published between 1990 and 2004 in English and held by 2 WorldCat member libraries worldwide
This film was originally made for television as part of a series produced by the Johns Hopkins University. The narrator, Lynn Poole, provides a brief history of the word "influenza" and the origins of the flu. Using illustrations and diagrams, Dr. Charlotte Silverman, chief of the Division of Epidemiology and Communicable Diseases, Maryland State Dept. of Health, describes the means of transmission. She gives examples of several pandemics, including the Spanish flu epidemic of 1918-1919, which caused 25 millions deaths worldwide. The film illustrates flu symptoms and duration, and traces its world-wide transmission. It shows the World Influenza Center in London. It demonstrates that antibodies built up in the blood by using a vaccine can prevent a flu outbreak. The film shows vaccine production

The master glassblower ( Visual )
1 edition published in 2004 in English and held by 1 WorldCat member library worldwide
The program opens with photos showing the versatility and expression of glass. Host Leo Geier explains that Johns Hopkins University employs full-time glassblower John Lehman because research scientists require intricate, complex glass equipment that no one has ever seen. Mr. Lehman demonstrates "pulling points" as he creates a ring seal for a trap. When Mr. Lehman first started blowing glass, there were only soft, soda, and lime glass varieties; now there are 75 different types and additional refinements are in process. A film covers the discovery of glass, from obsidian, natural glass used to carve weapons, vessels, and decorations, to the first manmade glass in 5000 BC and the Egyptians' glass jewelry and containers. Mr. Lehman demonstrates how to make a manometer from capillary tubing glass as well as the procedure in blowing a flask and a coiled glass tube. To demonstrate non-scientific aspects of the art, Mr. Lehman blows a swan, makes glass Christmas "snow," and completes a glass bird
A quintet concert ( Visual )
1 edition published in 2004 in English and held by 1 WorldCat member library worldwide
Members of the Baltimore Woodwinds, first chair or principle players with the Baltimore Symphony Orchestra, open the program playing the finale of "Quintet in E-flat major" by Anton Reicha. Lynn Poole describes the history of woodwind music and introduces the players: Britton Johnson on flute, Wayne Rapier on oboe, Robert Pierce on French horn, Stanley Petrulis on bassoon, and Ignatius Gennusa on clarinet. The quintet plays two movements of Vivaldi's "Sonata in G minor" and continues with "Pastoral," by modern composer Vincent Persichetti. Last in their repertoire are three short pieces for woodwind composed by Jacques Ibert
The geophysical patient ( Visual )
1 edition published in 2004 in English and held by 1 WorldCat member library worldwide
Lynn Poole summarizes some of the fourteen areas of activities taking place during the International Geophysical Year (IGY), 7/1/57 - 12/30/58: aurora and airglow, cosmic rays, geomagnetism, meteorology, solar activity, glaciography, gravity, ionospherics, longitude and latitude, oceanography, rocketry, satellites, seismology, and world days. IGY was timed to coincide with the high point of the eleven-year cycle of sunspot activity. A few of the highlights include Dr. William Markowitz's Moon Camera for measuring precise time, the use of the sea gravimeter to record changes in the earth's gravity, Dr. Harry Wexler's U.S. expedition to Antarctica to study atmospheric circulation and other meteorological phenomena, a recording of "whistlers" or low frequency radio signals caused by lightning flashes, John Simpson's study of primary and secondary cosmic rays, the use of the Baker-Nunn satellite tracking camera, and Dr. James Van Allen's Explorer I orbiting satellite

Where are you? ( Visual )
1 edition published in 2004 in English and held by 1 WorldCat member library worldwide
As historical background to 1959 Doppler radar navigation systems, an animated film considers the use of Ptolemy and Mercator's maps, the magnetic compass, and John Hadley's 1731 sextant. Clarence Rice, aviation products manager of the Bendix Radio Division in Baltimore, MD, points out that aviation navigation depends on knowing the ground speed and the path of the aircraft over the earth. He uses a chart to demonstrate the effects of winds on plane direction and the efforts to compensate: a homing device, which did not account for wind drift and also picked up static interference; the radio range system, which used four beams to overcome the drift problem but still received static; and the manual direction finder, which became the standard aid in the 1930s. A film describes how, in 1939, Bendix developed the automatic direction finder (ADF) with omnirange, which also eliminated static. Over the ocean, LORAN, or long range navigation, devices were used. Another animated film shows how Christian Doppler, in 1842, described the Doppler effect based on sound waves and how that principle has been applied to radar's radio waves. The film explains the "plus" Doppler effect for direct measurement of forward speeds and the "minus" for measurement of drift angle. Pitch and roll are also corrected by the radar beams since beam compensation is based on the magnitude of the Doppler shift. A plane's Doppler radar components include a transmitter, antennae, receiver, frequency tracker, and cockpit indicator. Mr. Rice explains how pilots divide their flights into shorter legs, placing the information into the navigational computer. He notes that Doppler radar will not become obsolete with faster aircraft speeds and that it does not require a land-based facility
Man going up ( Visual )
1 edition published in 2004 in English and held by 1 WorldCat member library worldwide
Lynn Poole interviews Dr. S. Fred Singer, associate professor of physics at University of Maryland, scientific consultant on U.S. Air Force's FARSIDE project, and father of the earliest practical satellite, MOUSE (Minimal Orbital Unmanned Satellite). Dr. Singer lists the primary contributors to propulsion: Newton, Tsiolkovsky, Oberth, and Goddard. He explains that the technical aspects of a rocket include propulsion, guidance, payload, and reentry. Currently chemical propulsion systems are used to launch rockets, but other propulsion systems, such as iron, photon, fusion, and fission, are being studied. Dr. Singer sketches a diagram to explain how gravitational pull and velocity make a satellite orbit and notes that a velocity greater than seven miles per second results in "escape velocity" and non-return of the satellite. The purpose of basic research, he says, is to train young people, such as the University of Maryland students who designed and built Terrapin and Oriole rockets

Heartbeat of the orchestra ( Visual )
1 edition published in 2004 in English and held by 1 WorldCat member library worldwide
Lynn Poole displays a chart of the orchestra sections: strings, woodwinds, brass, and percussion. Dr. William Hart, timpanist with the Baltimore Symphonic Orchestra and professor at the Peabody conservatory of Music, defines the elements of music: rhythm, melody, and harmony and demonstrates each of them on the piano, noting that the percussion instruments are the dispensers of rhythm. He gives a brief history of percussive music while showing instruments such as the timbro, castanets, cymbals, tambourine, and Chinese temple blocks. With the assistance of fellow timpanist Dr. William G. DeLeon, Dr. Hart demonstrates and explains the snare drum, the most common percussive instrument; the xylophone and its use in modern compositions such as the "Sabre Dance"; the cymbals and their contrasting use in Wagner's "Die Walkure" and Debussy's "Festivals"; and the kettle drums, or timpani, which can be tuned and which provide the heartbeat of the orchestra
Elephants are where you find them ( Visual )
1 edition published in 2004 in English and held by 1 WorldCat member library worldwide
Dr. George Carter, professor of geography at the Johns Hopkins University, discusses elephant drawings as the key to the controversy of whether or not the American Indian civilization was influenced by European and Asian civilizations. Examples of elephant drawings made between 1500 B.C. and 500 A.D. in such diverse places as England, Ceylon, China, and Siam are often stylized or abstract whether the animal is native to the country or not. Similarly, a Greek coin displays an elephant likeness. However, during this period in Central America, Mayan statues, carvings, and writings and Aztec art and rituals distinctly show elephants even though there were none to copy nor anyone to describe them. Thus Dr. Carter maintains that Asian peoples must have brought drawings or statues of elephants to Central America over 2,000 years ago. The proof he offers for this theory is the Thor Heyerdahl transpacific raft voyage (proving such a trip could be made in a primitive vessel), identical temples 12,000 miles apart in Mexico and Cambodia, identical Sumatran and Mexican folding bark religious books, identical fishhooks from Easter Island and California, physical attributes of Central American and Asian Indians (photos show one of each, both playing nose flutes), and plants appearing in lands too far from original sources to have blown there. In closing, Lynn Poole shows additional examples of elephant artwork found in the United States

Lynn Poole shows two children album pages of lasting gifts: the oldest hymn, "Gloria in Excelsis," inserted into Mass by Pope Telesphorus, sung by the Johns Hopkins Glee Club; the custom of Christmas cards, first designed by John Callcott Horsley at the request of his friend Henry Cole in 1843, and another card designed by W.M. Edgley; the story surrounding the composition of "Silent Night," with words by Father Joseph Mohr and music by Franz Gruber and sung by a duet; the history of the Christmas tree traced to Martin Luther; the development of Santa Claus by cartoonist Thomas Nast from Dr. Clement Moore's poem "A Visit from St. Nick"; the 1897 "Is there a Santa Claus" letter to "The New York Sun" and response from its editor Francis P. Church; the Welsh air "Deck the Halls" sung by a quartet; the Yule log custom; Johns Hopkins' President Milton S. Eisenhower's remarks on the significance of Christmas; and the composition of "Hark! The Herald Angels Sing" with words by Charles Wesley
Men who changed the world ( Visual )
1 edition published in 2004 in English and held by 1 WorldCat member library worldwide
Nicolaus Copernicus took issue with early astronomers such as Ptolemy, who wrote the "Almgest," a catalog of the motions of the planets and position of stars based on his use of an astrolabe. Costumed actors portraying Copernicus and his pupil Rheticus discuss astronomical theories and question the prevailing belief in the epicycles of planets in an earth-centered universe. However, their work was criticized by the church, including Martin Luther who considered the concept of the earth revolving and rotating to be "ludicrous." Danish astronomer Tyco Brahe combined the best findings from both Ptolemy and Copernicus, but did not accept the latter's heliocentric universe. Rheticus, however, wrote about that theory in his "First Account." Copernicus died in 1543, as his "Concerning the Revolution" was being published. Giordano Bruno defended the Copernican heliocentric theory and was tried as a heretic and burned at the stake
Red light for growth ( Visual )
1 edition published in 2004 in English and held by 1 WorldCat member library worldwide
This program opens with a film of the US Department of Agriculture's Agricultural Research Station in Beltsville, MD. In one greenhouse two groups of plants are receiving the same daytime conditions, but at night one is kept in total darkness while the other receives eight additional hours of incandescent light. Two four-year old loblolly pines show the results of this experiment. Dr. H.A. Borthwick explains that this is to study photoperiodism, or the effect of light on the plants' growth mechanism. In 1918 Wightman W. Garner and Harry A. Allard discovered that it is not the length of the day but rather of the night that is the determining factor in flower and seed production and growth of plants. Further experiments with lettuce, bean, tomato, and corn seeds test the effect of spectrum light colors and exposure on germination. A far red light creates a taller plant, and red light creates the tomato skin color. The mechanism in a plant the reacts to light is not chlorophyll but rather a two-way growth pigment, phytochrome, that acts as a switch with red and far red light. A film shows the process, using a spectrophotometer, by which this was determined. K.H. Norris demonstrates a spectrophotometer with a corn sample and explains the results with graphs. Two film clips show Sterling B. Hendricks doing further research on phytochromes to isolate their molecular structure and Soviet Prime Minister Nikita Khrushchev at Beltsville, MD listening to Dr. Borthwick discuss crop growth issues
