Invited Papers
ARMAND SPITZ LECTURE
REMINISCING: SELECTED PERSONAL EXPERIENCES BENEATH THE BIG AND SMALL SKIES
Prof. Richard Emmons
Abstract: The speaker recalls personal experiences selected from his multi-faceted 65-year career as an astronomy student, teacher, planetarian, and aerospace engineer. Two of his 27 slides are of letters received from Armand Spitz and Albert Einstein. Also appearing briefly in his script are such names as Heber D. Curtis, Fred Whipple, Ira Bowen, Allen Hynek, Leslie Peltier, and Orson Welles.
DRAGONS AT THE EDGE OF THE UNIVERSE!
Dr. George W. Collins II
Abstract: In which we attempt to convince the reader that the Universe is not the way it appears. The overall geometry is not that of Euclid, but is rather the geometry of space-time which has some peculiar properties. Looking out into the night sky, one looks back in time ultimately toward the origin of the Universe. That point in space-time is seen in any direction if one can look back approximately 12 to 15 billion years. Thus that point in space-time is mapped over the entire sky and clearly shows that the geometry of space-time is not that of Euclid. However, if one insists on imposing the geometry of Euclid on the Universe then he will be stuck with the concept of an “edge” just as 15th century man was with the notion of a flat earth. This leads to the unanswerable question “what lies beyond the edge?” We try here to replace that question with a more meaningful one and explore the consequences if that is not done.
METEORITES, MARTIANS, AND MICROBES: MARS UNDER THE MICROSCOPE
Dr. Ralph Harvey
Abstract: Our fascination with Mars has never been greater than it is right now, as fantastic new images and data from spacecraft galvanize public attention. The current excitement began last summer when NASA researchers announced that they had found possible traces of ancient Martian life-forms in the Antarctic meteorite ALH84001, and has continued with the robotic rovings of Pathfinder and Global Surveyor. All of these studies have revealed just how important the martian meteorites are in our understanding of the red planet, serving as the critical “ground truth” link between remote observations and the physical reality of a geologically active and alien world. This presentation will discuss what the martian meteorites tell us about Mars as well as the claims concerning the possibility of life on that planet.
ASTRONOMY UPDATE 1997
Dr. James Kaler
Abstract: From the Moon to the distant Universe, astronomers solved some mysteries, puzzled over others, and found new ones to examine. Mars revealed some of its secrets thanks to the Pathfinder mission, and the Universe became more understandable as the values of the Hubble constant and age approached consensus, we began to understand the formation of galaxies, and gamma ray bursts were seen optically. In between we delighted in a comet of the century, asteroids that act like comets and vice versa, the extension of the Solar System deeper into the Kuiper belt, new extrasolar planets, high-resolution probing of stars, an antimatter cloud near the galactic center, massive galactic black holes, and puzzlement about matter that falls into galaxies.
RETURN TO THE RED PLANET (OR, MY SUMMER ON MARS)
Dr. Geoffrey Landis
Abstract: Mars is one of the most interesting planets in the solar system, featuring enormous canyons, giant volcanoes, and signs that, early in its history, it might have had rivers and perhaps even oceans. In July, the Pathfinder mission landed on Mars, bringing with it the microwave-oven sized Sojourner rover to rove around on the surface and analyze rocks. Among the experiments on the mission was an experiment designed here at NASA Lewis to analyze dust deposition. Pathfinder is only the first of an armada of spacecraft which will examine Mars from the pole to the equator in the next decade, culminating (we hope!) with a mission to bring humans to Mars.
A FIELD TRIP TO THE MOON
Dr. Harrison Schmitt
Abstract: The last Apollo mission to the moon, Apollo 17, left Earth on December 7, 1972 to land near the southeastern edge of Mare Serenitatis in the Valley of Taurus-Littrow. For 75 hours, Gene Cernan and the author lived and worked in the valley, performing extensive geological studies of the volcanic rocks that partially fill the valley, the boulders that rolled into the valley from the surrounding mountains, and the meteor impact generated soils that cover the valley floor and walls. Successful exploration of Taurus-Littrow capped a six mission investigation of the materials and history of the moon. At the conclusion of these studies, science had gained a first order understanding of the evolution of the moon as a planet. Humankind had gained knowledge of new resources in the soils of the moon that may help solve many energy problems on Earth and help initiate the exploration and settlement of Mars.
Contributed Papers
LASER SPIROGRAPHS

AN ALIEN ODYSSEY
Robert J. Bonadurer
Abstract: In producing a new planetarium show on aliens, my curiosity grew about who believes in aliens and why? This paper will look at some personal alien odysseys, an abbreviated history of alien beliefs, and current beliefs in aliens and why.
STRASENBURGH PLANETARIUM UPDATE
Steve Fentress
Abstract: As it approaches age 30, Strasenburgh Planetarium is changing to adapt to changes in its social, political, educational and philanthropic environment. Trends include current-events star shows, 8/70 films, educational laser shows, collaboration with scientists, better school reservation services, new volunteer and intern programs, and a Challenger Center.
SAGA OF SIBERIA’S PALLAS METEORITE
Prof. Roy Gallant
Abstract: In July 1997, the author organized a six-person expedition to the remote mountain site of the fall of the world’s most famous meteorite, the Pallas Iron. The 1.5-ton meteorite fell in south-central Siberia without leaving a crater. It was discovered in 1794, and subsequently it was instrumental in the establishment of the science of meteorites in the 1800s.
HANDS-ON ASTRONOMY ACTIVITIES
Michael Gardner
Abstract: On July 1, 1994, the Longway Planetarium became part of the Flint Cultural Center Corporation. The resulting move in the change in governance and philosophy has changed the Planetarium’s role in the educational process. This coupled with the added competition of other venues for “field trip” options and the Michigan State emphasis on science goals and objectives is changing the manner in which the Longway Planetarium will offer its programs. One such aspect is in the pre and post visit materials. This talk will detail the reasons for this change, to include techniques for classroom exercises based upon the Flint Cultural Center School. A reference listing of materials and sample activities will be distributed.
BREATHE LIFE INTO LIVE SHOWS WITH SOUND EFFECTS
Geoff Holt
Abstract: With a palette of sound effects available at the click of a mouse, you can use your personal computer to accent stories and punch lines, provide game-show- like feedback, or add some auditory ambiance to a live program. Techniques will be presented for locating, recording, and playing sound files on both the Macintosh and Windows platforms. The key is making the sound effects readily available during your live planetarium show.
FOLLOW THE LEADER: IT DOES MAKE A DIFFERENCE
Dr. David Hurd
Abstract: The effectiveness of a novel setting, such as a planetarium, can be enhanced by the type of facilitator present. This paper presents evidence supporting the increased effectiveness of trained classroom teachers OVER a planetarian while presenting a lesson. This evidence comes from the results of a study conducted at the Edinboro University Planetarium during the 1996-1997 school year. Implications of this study will be discussed and recommendations given for both portable and permanent planetarium facilities.
EXPANDING ONE’S UNIVERSE WITHOUT THE HUBBLE CONSTANT

RETYING THE THREAD BETWEEN ASTRONOMY AND MYTHOLOGY
Sharon Shanks
Abstract: In the 20th century, the study of mythology seems to be drifting farther and farther away from the stars, a phenomenon caused as much by light pollution as it is by the passage of time and our increasing sophistication. We can study mythology without looking at the stars and, of course, can study the night sky without knowing mythology – but each loses something when they are studied along.
BASIC SPECIAL EFFECT DESIGN: MORE BANG FOR YOUR BUCK
Bryan Siegfried
Abstract: Many smaller planetariums have one difficulty in common – they have small budgets to match. However, seeing that special effects are for the most part just tricks of light, there are several ways that you can manufacture these gizmos with parts you probably already have.

CLYDE TOMBAUGH
Dan Francetic
Abstract: Clyde Tombaugh passed away early in 1997. He was the discoverer of the planet Pluto. His brother lived in the Cleveland area, and his sister-in-law taught chemistry for many years at Euclid High School. She gave me the articles, pictures, and a Clyde Tombaugh-autographed, annotated, and signed scale model of the solar system using the earth as a 1″ diameter object which I used in the poster display.
BIRTHDAY PLANET POSITION EXERCISE
Dan Francetic
Abstract: This exercise uses data from the Macintosh computer program, Voyager II, to enable students to plot the positions of the planets in their orbits for the students’ birthdays. They must measure angles between the Sun and each planet. They then can answer questions dealing with such things as the planets in the morning sky, nighttime sky, closest to conjunctions, oppositions and various other significant planet positions. Sky printouts from Voyager II can then be used to check student results.
EUCLID STUDENTS TALK TO DISCOVERY CREW
Dan Francetic
Abstract: In July of 1995, seven Euclid students talked to an astronaut via ham radio while she was orbiting over South Africa. She is the daughter of a Euclid second grade teacher and has talked to Euclid students on three different occasions. Such an event involves an entire school district and an entire community. Local ham radio people made this event possible. The project is called SAREX and is run through AMSAT, the Radio Amateur Satellite Corporation.

REASONS FOR THE SEASONS
Susan Reynolds
Abstract: The activities presented are meant to satisfy students’ needs for feeling accepted, significant and powerful in the academic environment. Added to that is an opportunity to have fun viewing the changing sky in an unusual environment–the planetarium as a laboratory.
FILLING THE ASTRONOMICAL VOID: A VISUAL MEDIUM FOR A VISUAL SUBJECT
Jay Ryan
Abstract: Astronomy is a fundamentally visual subject. The modern science of astronomy has at its foundation the ancient art of visually observing the sky. The visual elements of astronomy are arguably the most important to the average person. Every person in the entire world is affected by visually-observed astronomical phenomena such as the seasonal variations in daylight. However, misconceptions abound and the average person cannot recognize the simple signs in the sky that point to the direction, the hour, and the season.
TEACHING PASSIVE SOLAR HEATING IN THE PLANETARIUM
Sheldon Schafer
Abstract: Lakeview Museum recently hosted “Planet Neighborhood Day” in conjunction with the PBS series of the same name. The focus of the series was on things the individual citizen can do to improve the environment. In order to involve the planetarium with a hands-on activity that day, we developed an activity on passive solar heating. Participants built houses of “Mega Blocks” and used the planetarium to simulate the height of the winter and summer Sun. The goal was to find the best combination of window size and roof overhang, so that the windows of the house would admit the winter Sun and be shielded from the summer Sun.
ADDING MACHINE ASTRONOMY

Abstract: This paper tells how adding machine tape can be used to model different ideas involving distances in astronomy. It is cheap and you may have a supply sitting around at your school.
RARE MORNING SPECTACLE ON APRIL 23
Robert Victor
Abstract: Here’s a celestial event planetarians may want to publicize in advance to their audiences, and perhaps even schedule a couple of mornings of public viewing to see it, despite the early hour. The sight of two bright planets approaching each other in the weeks preceding April 23 will alert regular morning skywatchers to the upcoming event.
TWILIGHT ASTRONOMY 1998-1999
Robert Victor
Abstract: Twilight Astronomy is an activity individuals, classes, and families can enjoy. Regularly spending a short time outdoors in deepening twilight, watching the Moon, planets, and bright stars, is a good way for beginners to learn the basic rhythms of the sky.
CARA KIDS ON THE RED PLANET
April Whitt
Abstract: The 1997 Yerkes Summer Institute featured activities and classes about the solar system.
