The Beginning
No full textBefore the creation of our Universe, information did not exist. No bits, no particles, no life, no agreements. Often people question me: "What was there before the Big Bang?" or, "Where is our Universe expanding in?".</p
Introduction
No full text"Where are we?", "where do we come from?", or better "what is It?". Fifty years ago I decided to become an astronomer, inspired by the Westerbork Synthesis Radio Telescope. The radio data would bring me into deep space and help answer big questions.</p
IT from Bit
No full textBoth in physics (in vivo) and in Information Theory (in vitro) the total amount of information in a confined system is perceived as entropy: S in physics, i in Information Technology.</p
Deep Space
No full textCERN's Large Hydron Collider (LHC) in Geneva is currently the record holder in acquiring huge amounts of experimental science data. The reason is simple: the target particles are extremely rare and are searched for in an ocean of other events. In 2019 CERN's advanced tape storage system Castor held 330 petabytes, in a very sustainable way compared to the energy-consuming spinning disks. CERN is already planning for tape systems two times bigger in 2022, and five times bigger in 2026.</p
People’s information Universe
No full textItem does not contain fulltextInformation exists when it is being copied—a rather important notion—think of bits, DNA and lottery. This concept is highlighted by Shannon’s classical paper on Information theory which describes a mathematical theory of communication, communication being equal to the copying of information. The second leading notion is that the copying process only works when agreements have been made. Actually, everything we do with computers is based on agreements among people— often in the form of standards
The ESO-LV project - Automated parameter extraction for 16000 ESO/Uppsala galaxies
No full textA program to extract photometric and morphological parameters of the galaxies in the ESO/Uppsala survey (Lauberts and Valentijn, 1982) is discussed. The completeness and accuracy of the survey are evaluated and compared with other surveys. The parameters obtained in the program are listed
Edwin Gaustad oral history interview.
No full textOral history interview with Edwin Gaustad conducted by David Marshall, originally recorded May 1, 2007, in Santa Fe, New Mexico. Accompanied by one finding aid.Dr. Gaustad, a retired history professor and renowned author of American religion, talks about his life, family, education, publications and interests
