The Snowmass Process is a particle physics community planning exercise sponsored by the Division of Particles and Fields of the American Physical Society. [1] During this process, scientists develop a collective vision for the next seven to ten years for particle physics research in the US. [2]
Sara Imari Walker is an American theoretical physicist and astrobiologist with research interests in the origins of life, astrobiology, physics of life, emergence, complex and dynamical systems, and artificial life.
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.
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.
In cosmology, the anthropic principle, also known as the observation selection effect, is the proposition that the range of possible observations that could be made about the universe is limited by the fact that observations are possible only in the type of universe that is capable of developing intelligent life.
Emanationism is a theory in the cosmology or cosmogony of certain religious and philosophical systems, that posits the concept of emanation.According to this theory, emanation, from the Latin emanare meaning "to flow from" or "to pour forth or out of", is the mode by which all existing things are derived from a 'first reality', or first principle.
A nitrogen generator Bottle of 4Å molecular sieves. Pressure swing adsorption provides separation of oxygen or nitrogen from air without liquefaction. The process operates around ambient temperature; a zeolite (molecular sponge) is exposed to high pressure air, then the air is released and an adsorbed film of the desired gas is released.
The Universe for Beginners, republished as Introducing the Universe, is a 1993 graphic study guide to cosmology written by Felix Pirani and illustrated by Christine Roche.The volume, according to the publisher's website, "recounts the revolutions in physics and astronomy," from "Aristotle to Newton," and, "Einstein to Quantum Mechanics," "that underlie the present-day picture of the universe."
