'Magical Windows' Turn Science into Artistic Form
By JACK HAWKS
Kansan Staff Reporter
Apparently, the sandbox is making a comeback as an object for play. For it is in the arena in which a new art form, holography, is rapidly developing.
Holography, or three-dimensional laser photography, began in scientific experiments 10 years ago and made its debut at the University of Kansas this year. Two KU students are among the first in the country to perform holography as an artistic expression.
Paul Linden, Soux City, Iowa, senior, and Barney Wages, Leenaja minor, have built a half-ton, waist-high sandbox on the fourth floor of Hall And are using it as the base from which they are producing holograms.
SIMPLY PUT, holography is a system of making a three-dimensional image with a laser, and a hologram is the flat, rectangular glass plate containing that image.
More accurately, a bologram is a record of the interference pattern caused by two light waves.
reference beam and the other an object beam.
Wages' and Linden's set-up has a 4" x 4"
cinder block sandbox with sand nearly
filling it. On the sand is a smaller box which
contains several glass lenses and mirrors
that can be mounted to the glass film
plate is in the center, and the object to be
photographed is directly behind it.
The process of production involves aming the laser, which is adjacent to the sandbox, at a highly polished piece of glass that has exactly transparent sides. This makes it possible to observe the difference beam travels to the film plate, and the object beam travels to the object.
BOTH BEAMS are reflected by lenses and mirrors to their respective end. When the set-up of the lenses is accurate, both sides of the film plate (a glass plate covered with emulsion) and the object are illuminated.
The laser light exposes the film plate for an average of 15 seconds, Wages said, and the plate is developed similarly to that of a black and white photograph.
For a hologram to develop, two things
must occur. First, the distance of the two light beams must be equal. That is, the distance of the reference beam from the beam-splitter to the plate must equal the distance of the object beam from the beam-splitter to the object and then to the plate. Secondly, during exposure the entire area must be vacated in order to insure stability.
"STABILITY in holography is very important," Wages said. "Any movement of one-hundred-thousandth of an inch or less during exposure can ruin the
Linden got the idea from an article on lithography in Rolling Stone magazine, and he and Wages took a course last fall at the San Francisco School of Lithography. They intend to take a second course there in August.
At the Electronics World show in Kansas City, Mo., this past weekend, Linden and Wages, both fine arts majors, displayed a model and several of their hoariums.
Holography seems to have a mysterious appeal to laymen. Wages said, because the system is so difficult to use,
than any other exhibit at the show. Other exhibits included David Beauty Electronics, as well as other leading Kansas City sound systems outlets.
WHEN ASKED by the newness of the venture, Linden said he thought they were two of the first people in the United States to experiment with holography from an artistic standpoint rather than a scientific one.
"We are trying to make it a viable artistic expression," Wares said.
Both students are excited about the prospects for bibliography and both intend to be active in their studies.
Linden said that holograms were "kind of like magical windows" and that in five to ten years "we should have some sort of holographic television." He also predicted other exciting future prospects such as recording brain images.
"BRAIN WAVES are gamma waves," he said, "and perhaps within 50 years, a process can be developed to record brain waves using the laser with a gamma ray source."
Unlike regular photography, all of the
Concerts, Cultural Center Urged
Supporting city band concerts, working on the Cultural Arts Center and the Lawrence Bicentennial Committee are summer activities scheduled by the Lawrence Arts Commission, according to the criticism, secretary of the commission.
The Lawrence Arts Commission was adopted last December by the city commission, Hutchison said Saturday. The commission has not primary power, but acts as a "watchdog" over the quality of coming into the Lawrence area, she said.
"We offer suggestions and additions to projects already formulated," Hutchison said. All art brought to or on loan to the city, architecture and landscaping, as well as all
artistic events, must be approved by the commission before the city may accept
THIS SUMMER the arts commission will be working in support of the summer band concert held in South Park, Hutchison said, and the park will be home to the South Park annual for the past six years.
The commission, Hutchison said, is especially concerned because funding for the project has been cut.
In the past these concerts were supported by the local Musician's Union No. $12 she

secretary, of the local musician's
The union was allocated about $3,000 from the Music Performance Trust Fund this year, Jerome said. The city band will receive $2,700 of this.
It costs about $800 to put on a concert and with the union allotment three concerts are for, William L, Kelly, RU registrar and director of the city band, said.
THERE WILL BE CONCERTS from 8 to 19 p.m. on June 12, 19 and 26, Kelly said. That, with the exception of the July 4 concert which is free, will be all unless additional fees are charged.
Kelly said that he thought it was an obligation of the city to assist the musician.
union in putting on the concerts.
The city commission gave $500 at the beginning of the year to the summer concert event. The city commission will appear before the city commission May 7 to ask for more funds and to investigate the possible reinstitution of a city band tax which was last enforced about 1958, she said.
The city attorney was asked to investigate the law, according to Paul Gray, member of the arts commission. Gray said that no one knew why the tax was discontinued, but that it would be beneficial in continuation of the program.
Mud Creek 'Contract' Breached
Lawrence Officials Testify to Committee in Washington
Rose and several other Lawrence officials testified before the Appropriations subcommittee of the Senate Public Works Committee in Washington.
The federal government "broke a contract" with Lawrence by not completing the Mud Creek channelization project as a result of a lack of support from a Congressional subcommittee yesterday.
Progress on the Mud Creek project has been stalemated since December when the U.S. Army Corps of Engineers abandoned the Mud Creek and Creek five miles northwest of Lawrence.
The Corps abandoned the plan because, it
Percussionists' Concert Tonight
The ensemble will perform "Arts and Cadenzas" by Stanley N. Shumway, professor of music theory, Shumway wrote the piece for the KU ensemble and this will be the piece's first performance on campus. Shumway is on sabbatical in England.
The spring concert of the University of Kansas Percussion Ensemble will be at 8 tonight in the University Theatre. The concert will be directed by George Bobern.

said, channeling would be significantly more expensive than not channeling to the
Although the switch saved the federal government $2.18 million, city and drainage district costs have risen $350,000. And Douglas County officials estimate an additional $470,000 will be required to fix bridges and roads that would have been repaired in conjunction with the original plan.
The city had already purchased land rights-of-way along the portion of the creek to be channelized. However, the Corps now says the land won't be needed.
The arts commission to get the Lawrence Cultural Arts Center project in action by this fall, Marilyn Brown, vice president of the arts commission said.
The original plan would have involved clearing the Mud Creek channel of debris and timber, straightening out some of the bends in the stream, sloping the banks and constructing a high levee on the south bank of the stream.
Under the new plan, the creek channel would be left in its natural state and the levee would be constructed on a ridge that overlooks the stream up to a half mile to the south.
"We believe this would be an unwarranted exclusion," the group said in a prepared statement, "and a direct breach of contractual obligation if we were dealing with anyone other than the federal government."
Appearing before the committee were city commissioners Barkley Clark, Nancy Hambleton and John Emick; Wesley Brune, president of the Kaw Valley Drainage District; George Faler, president of the Kaw Basin Water Management

"The lake will provide much needed flood protection and recreation for this downstream area of Kansas," Docking said in a report to the subcommittee delivered in Washington by Torn Van Cleve, Docking's legislative liaison representative.
In related action, Gov. Robert B. Docking submitted testimony to a House Appropriations subcommittee in favor of continued funding for Clinton.
The project involves the renovation of the former Carnegie Library building, 9th and 10th floors.
THE CENTER would be a coordinating center for all community art activities, she said, providing space for exhibits, studios, recitals, plays, plays meetings and lectures.
The project will take about $80,000 to put into operation, Brown said. The city has committed $24,000 for renovation and can secure the commission can secure the cost of the money.
The arts commission will submit a request to the Kansas Cultural Arts Commission in Lindsborg on Friday for $21,000 for operating expense assistance, Brown said.
The arts commission is also working closely with the Lawrence Bicentennial committee, Hutchison said. Plans being considered include the building of a new park in commemoration of Lawrence's 30th birthday. A 30-minute film on Lawrence, she said.

“It’s too bad holography didn’t come along a little sooner,” Linden said, “because had the Watergate tapes been reproduced on holograms, there would not be any thought of tape erasures or altering.”
