Cassette tapes from the 1983 and 1985 Hawaii Conference in High Energy Physics. Includes K. Berkelman, J. Ellis, H. Georgi, and C. Rubbia talks given in 1983; the majority of the 1985 meeting plus tapes of Dalitz, Fitch, Flugge, and Zachariasen including video of the Public Discussion session and Leon Lederman's public lecture on "Inner Space and Outer Space." The Lederman lecture is described as specifically for the non expert, high school student, house wife, and the general community at large. Briefly Inner Space deals with the small dimension of fundamental particles of nature while Outer Space deals with the large dimension of our universe and cosmology. Hence a public talk on Inner Space and Outer Space relates the very small with the very large, and thus comprises all of nature and our existence.
