Process and Reality is a book by Alfred North Whitehead, in which the author propounds a philosophy of organism, also called process philosophy. The book, published in 1929, is a revision of the Gifford Lectures he gave in 1927–28.
A sample of 229 nearby "thick" disk stars has been used to investigate the existence of an age-metallicity relation in the Galactic thick disk and indicates that there is an age-metallicity relation present in the thick disk. [13] [14] Stellar ages from asteroseismology confirm the lack of any strong age-metallicity relation in the Galactic ...
Evolution of a University [permanent dead link ], a series on ASU's history and future plans printed in The State Press from Nov. 4–6, 2008 50 years ago, voters endorse name change for Arizona State; Longtime employees look back at past 50 years’ ASU presidents; Crow’s vision attracts both praise, criticism
Without major changes to the Big Bang theory itself, BBN will result in mass abundances of about 75% of hydrogen-1, about 25% helium-4, about 0.01% of deuterium and helium-3, trace amounts (on the order of 10 −10) of lithium, and negligible heavier elements. That the observed abundances in the universe are generally consistent with these ...
A cosmological phase transition is an overall change in the state of matter across the whole universe. The success of the Big Bang model led researchers to conjecture possible cosmological phase transitions taking place in the very early universe, at a time when it was much hotter and denser than today.

New College is located on ASU's West Valley campus. The college resembles a traditional liberal arts and science college, but with an interdisciplinary focus, in which faculty are grouped into broad divisions rather than discipline-specific departments. [ 1 ]
Image stacking. To put all of the light in a single place, each segment image must be stacked on top of one another. In the image stacking step, the individual segment images are moved so that they fall precisely at the center of the field to produce one unified image. This process prepares the telescope for coarse phasing.
