Dr. William Grant Tifft, Astronomy Professor Emeritus at the University of Arizona, has been recognized by Marquis Who’s Who Top Educators for dedication, achievements, and leadership in astronomy.

Drawn to the wonder and beauty of the nighttime sky, Dr. Tifft knew he would be a scientist since his youth. Settling on a career in astronomy, he went on to receive a Bachelor of Arts from Harvard College in 1954, graduating in the top 10 percent of his class allowing him to join Phi Beta Kappa. In 1958, he obtained a Doctor of Philosophy from the California Institute of Technology. That same year, Dr. Tifft commenced his career as a postdoctoral fellowship with the Australian National University in Canberra, Australia, lasting until 1960. The following year, he became a research associate with Vanderbilt University in Nashville, Tennessee before serving as an astronomer with Lowell Observatory in Flagstaff, Arizona from 1961 to 1964.

Pivoting to a career within the realm of education, Dr. Tifft joined the University of Arizona in 1964. For nine years, he excelled as an associate professor of astronomy before being promoted to a full professor of astronomy in 1973. After a tenure of more than 40 years at the institution, Dr. Tifft attained emeritus status in 2002. Despite his retirement, Dr. Tifft remains active as a fellow of the American Astronomical Society and a member of the International Astronomical Union and Phi Beta Kappa. A trustee of the William G. and Janet A. Tifft Revocable Trust, he became the founder of the small Heritage Fund for Arts and Sciences in 2016.

Looking back on his illustrious career, one of Dr. Tifft’s greatest achievements is his discovery of redshift quantization and correlations relating to it, including variability in quantum steps. He was the first astronomer to detect voids in the mapping of large-scale supercluster structure and he conducted investigations on three-dimensional time in cosmology and particle physics, leading him to develop a new alternate quantum temporal cosmology. Dr. Tifft recalls his apt for research dates back to his time as a National Science Foundation predoctoral and postdoctoral fellow in the 1950s. He attributes his career success to his unwavering drive from childhood to carefully observe and understand what our universe, space and time really means.

Alongside his years of research, Dr. Tifft is a contributor to more than 100 articles in professional journals. In 2014, he authored, “Redshift Key to Cosmology,” which has been received with much acclaim. In addition, he is a joint editor of “Modern Mathematical Models of Time and Their Appreciation to Physics and Cosmology” from 1997 and a joint author of, “Revised New General Catalog” from 1973. Looking ahead, he plans to continue researching in further development and understanding of Quantum Temporal Cosmology. To attest to his legacy, Dr. Tifft can also be found in numerous editions of Who’s Who in America, Who’s Who in American Education, Who’s Who in Science and Engineering and Who’s Who in the West.

For Dr. Tiftt, his work in cosmology can simply be stated as being built upon steps driven by an escapement that is centered in space, space is the escapement or contains the escapement process which is ordinary motion dynamics which is what runs the escapement and drives the cosmology in steps.
