In Search of the True Universe
This book examines how our understanding of the cosmos advanced rapidly during the twentieth century and identifies factors contributing to this progress.
Cosmic Discovery
The search -- Discoveries -- Observation -- Detection, recognition, and classification of cosmic phenomena -- The fringes of legitimacy : the need for enlightened planning.
An Exhibit Denied
None
Cosmic Messengers
Focusing on the ultimate limits of observational astronomy, Harwit explores how well we will ever understand the Universe.
An Exhibit Denied
At 8:15 A.M., August 6, 1945, the Enola Gay released her load. For forty three seconds, the world's first atomic bomb plunged through six miles of clear air to its preset detonation altitude. There it exploded, destroying Hiroshima and eighty thousand of her citizens. No war had ever seen such instant devastation. Within nine days Japan surrendered. World War II was over and a nuclear arms race had begun. Fifty years later, the National Air and Space Museum was in the final stages of preparing an exhibition on the Enola Gay's historic mission when eighty-one members of Congress angrily demanded cancellation of the planned display and the resignation or dismissal of the museum's director. The Smithsonian tnstitution, of which the National Air and Space Museum is a part, is heavily dependent on congressional funding. The Institution's chief executive, Smithsonian Secretary I. Michael Heyman, in office only four months at the time, scrapped the exhibit as requested, and promised to personally oversee a new display devoid of any historic context. In the wake of that decision I resigned as the museum's director and left the Smithsonian.
Astrophysical Concepts
My principal aim in writing this book was to present a wide range of astrophysical topics in sufficient depth to give the reader a general quantitative understanding of the subject. The book outlines cosmic events but does not portray them in detail-it provides aseries of astrophysical sketches. I think this approach befits the present uncertainties and changing views in astrophysics. The material is based on notes I prepared for a course aimed at seniors and beginning graduate students in physics and astronomy at Cornell. This course defined the level at which the book is written. For readers who are versed in physics but are unfamiliar with astronomical terminology, Appendix A is included....
Highly Ejected [J
"We present the first observations of the J = 16 to J = 15, 162.8 um transition of CO from an astronomical source. These measurements were carried out on the Kleinmann-Low Nebula"-P. 2.
